In this embodiment, one hoistway 7 is provided with, for example, three cars 1a, 1b, 1c.

A high-rise main rope 2a for pulling the high-rise cage 1a, a high-rise balance weight 6a connected to the main rope 2a to balance the high-rise cage 1a, and a high-rise hoist 3a. A reverse U-shaped rope drive system is configured with a sheave 4a for high floors which is driven by the above and the main rope 2a for high floors is wound around, and the car 1a for high floors is moved up and down in the hoistway 7. High floor basket 1
The ascending / descending of a is controlled by driving the high floor hoisting machine 3a by a control device (not shown). The same applies to the middle and lower floors. In addition, the rope drive system for the lower floors is formed so as to overlap with the rope drive system for the middle floor so as to cover the rope drive system for the middle floor in the ascending / descending direction. Furthermore, a rope drive system for high floors is stacked on top of it so as to cover it in the vertical direction without contact. For this reason, the inverted U-shaped bulge expands as the rope drive system is located above the overlap of the overlapped rope drive systems.

When this elevator apparatus is installed, the car 1 is moved up and down in the Z direction, and in a plane vacant with the car 1, the main ropes 2, and the counterweight 6, a direction orthogonal to the Z direction, for example, a direction in and out of the car 1. Is the Y direction, the direction orthogonal to Y and Z is the X direction, and the plane formed by the inverted U-shape of the rope drive system is the moving plane. Furthermore, the one with the door of the car 1 is the front,
The side with the counterweight 6 is the rear surface, the YZ plane is the side surface, the upper part of the car in the Z direction is the upper surface, and the lower part is the lower surface. Also, FIG.
FI is the boarding floor, FH, which is the standard for people and cargo to board.
Indicates a high floor, FM indicates a middle floor, and FL indicates a low floor.
In this embodiment, for example, the movement planes of the rope drive systems on the upper floors, middle floors, and lower floors are substantially the same plane. A schematic top view of this elevator device is shown in FIG. The size of the car is such that, when the lower car is configured to be larger than the upper car, and the plurality of cars 1a, 1b, 1c arranged in the hoistway are projected on the XY plane, at least the main car of the lower car is projected. The part that connects the cords projects more than the car above.

When the locus of movement of the balance weights of the rope drive system is taken as the movement line, all the movement lines of the plurality of balance weights 6a, 6b, 6c of the rope drive system form a substantially flat surface, and in particular, this embodiment In the example, a plane parallel to the Z axis is formed. Further, at least one of the plurality of rope drive systems, for example, the folding position of the main rope 2a for high floors is arranged at a position where the entire hoisting stroke (FL, FM, FH) of the hoistway 7 can be moved. The folding position of the rope drive system, for example, the main ropes 2b for the middle floor is arranged at a position where a part (FL, FM) of the entire lifting process can be moved. Further, for example, the folding position of the main rope 2c for the lower floors is arranged at a position where a part (FL) of the entire ascending / descending stroke can be moved.

Each of the rope drive systems for the lower floors, the middle floors and the higher floors has almost the same structure as the conventional one, and its operation will be described below. Each sheave 4a,
4b, 4c are rotated by respective hoisting machines 3a, 3b, 3c, and power is transmitted by traction with the main ropes 2a, 2b, 2c wound around the sheaves 4a, 4b, 4c. Baskets 1a, 1b, 1c and counterweights 6a, 6b, 6
c is each cage 1a, 1b, 1c and counterweight 6a,
The cages 1a, 1b, 1c are vertically moved along the guide rails 8 by being guided by the guide rails 8 via guide shoes (not shown) provided on the guide rails 6b, 6c. As for the raising and lowering of each car, the drive of the hoisting machines 3a, 3b, 3c is controlled by each control device (not shown) to operate.

When a plurality of rope drive systems are arranged in one hoistway 7 as in this embodiment, the hoist 3a,
This arrangement will be described because the arrangement of 3b and 3c and the roping of the main ropes 2a, 2b and 2c become complicated. In the configuration as shown in FIG. 1, the rope drive system for the uppermost upper layer does not pose a problem, but for the middle layer and the lower layer, the main rope 2 is passed through the hoistway 8 so as not to contact the upper car 1. Must be placed. Therefore, in this embodiment, when the size of the car 1 is changed and projected on the XY plane as shown in FIG. It is configured by shifting. For this reason,
The car 1 or a part of the car is protruding, and the main floor main ropes 2b and the low floor main ropes 2c are configured to pass through the rear surface of the high floor main ropes 2a.

The operation system of the elevator apparatus of this embodiment will be described below. In this example, three rope drive systems consist of a high floor (FH), a middle floor (FM),
It is configured to service each zone of the lower floors (FL). FIG. 3 is an explanatory diagram showing an example of an operation system when the zoning service according to this embodiment is performed.
In this example, it is assumed that there are the most elevator users at work, and there are no passengers going down. The operation procedure is shown below. The car 1a for higher floors operates in the order of boarding (t1) → going express operation (t2) → services on each floor (t3, t4) → return express operation (t5). Mid-floor basket 1b
Will operate in the order of car 1a departure waiting (t1) → boarding (t2) → express operation (t3) → service (t4) on each floor → return express operation (t5). Lower floor car 1c is car 1
a, 1b waiting for departure (t1, t2) → boarding (t3) →
Service on each floor (t4) → return express operation (t5).

In this embodiment, a plurality of inverted U-shaped rope drive systems are stacked in one hoistway so as to cover each other in a non-contact manner, and a plurality of cars are provided in one hoistway. Each one can drive safely and stably independently,
Since the transport amount per hoistway area can also be increased, the total plane space of the hoistway can be reduced. In particular, in order to construct a plurality of inverted U-shaped rope drive systems in a single hoistway so that they can be raised and lowered without contacting each other, as shown in FIG.
The positions of a, 5b, 5c are shifted to the rear part so that the main ropes 2a, 2b, 2c do not come into contact with each other. In addition, by changing the size of the car, the connecting portion between the main ropes for middle floor 2b and the car for middle floor 1b is shifted to the rear of the joint portion between the main ropes for high floor 2a and the car for high floor 1a, and The connecting portion between the main ropes 2c for the lower floors and the car 1c for the lower floors is shifted to the rear of the connecting portion for the middle floors. Therefore, the main rope 2 can be smoothly moved up and down, and the size of the lower car is made larger than the size of the upper car. Therefore, the capacity (capacity) of the lower car 1 can be increased.
There is also an effect that more people can be transported to lower floors, which is considered to be actually used by many people.

Further, since the moving planes of the plurality of rope drive systems are substantially one plane in the YZ plane, the moving lines of the three counterweights 6a, 6b, 6c are substantially one plane in the Y direction at the rear of the car. Can be configured to line up. Therefore, the counterweights 6a, 6b. The guide of 6c can be used also and can be made compact, and the device can be made small. Further, the entire ascending / descending stroke of the hoistway 7 is divided into a plurality of zones, which are assigned to the zones in order from above the car, and the cars are simultaneously operated in each zone. Therefore, a large number of passengers can be lifted and lowered in one hoistway 7, and the zone service, which was conventionally performed in a plurality of hoistways, can be performed in one hoistway.
For example, when going to work in the morning as shown in FIG.
About twice as many people can be transported.

5A is a top view and FIG. 5B is a side view. In one hoistway, a plurality of inverted U-shaped rope drive systems are stacked so as to cover each other in a non-contact manner, and in this embodiment, the moving planes formed by the inverted U-shapes of the three rope drive systems are substantially parallel to each other. Configured in parallel. Since the moving planes are parallel to each other, even if the inverted U-shaped bulges of the rope drive system for the lower floors and the rope drive system for the middle floors are the same, 2
The two rope drive systems do not touch. The inverted U-shaped bulge of the rope drive system for higher floors is larger than the lower two.

In the figure, 15a is a notch part provided at the rear two corners of the car 1a and 15b is for the middle floor. It is a cutout portion provided at one corner of the rear portion of the car 1b. When the plurality of cars 1a, 1b, 1c arranged in the hoistway are projected on the XY plane by this cutout portion, at least a portion of the lower car, which is connected to the main ropes, projects more than the upper car. Therefore, the cutout portions 15a, 1
The main ropes connected to the car below it can pass through 5b without contacting the car above.

Also in this embodiment, as in the case of the first embodiment, a plurality of inverted U-shaped rope drive systems are stacked in one hoistway so as to cover each other in a non-contact manner.
Since multiple cars can be independently and safely operated in one hoistway and the amount of transportation per hoistway area can be increased, the total plane space of the hoistway can be reduced. Further, since the moving planes of the plurality of rope drive systems are set to be substantially parallel to each other, the moving lines of the three counterweights 6a, 6b, 6c are arranged in the rear part of the car on a substantially flat plane in the X direction. The counterweight 6a,
6b. The guide of 6c can be used also and can be made compact, and the device can be made small. Furthermore, in a limited space, the intervals between the rope drive systems can be widened, and the risk of contact between the main ropes 2 can be reduced. Also,
By arranging a plurality of rope drive systems in this way, it is easy to arrange the hoisting machine and the sheaves 4a, 4b, 4c.

Example 3. Hereinafter, an elevator apparatus according to a third embodiment of the present invention will be described with reference to the drawings. FIG. 7A is a top view schematically showing the elevator apparatus according to the third embodiment,
FIG. 7B is a side view. In a hoistway, a plurality of inverted U-shaped rope drive systems are stacked so as to cover each other in a non-contact manner. Z
It was configured to be substantially parallel to the axis and for each of the planes of movement to intersect each other. Moreover, since it comprised in this way, even if the reverse U-shaped bulge of the rope drive system for lower floors and the rope drive system for middle floors is the same, two rope drive systems will not contact. The inverted U-shaped bulge of the rope drive system for higher floors is larger than the lower two. Further, in the second embodiment, a notch is provided at the rear of the lower car so that the main ropes connected to the lower car can pass without coming into contact with the upper car.
Is the same as.

Also in this embodiment, as in the case of the first embodiment, a plurality of inverted U-shaped rope drive systems are stacked in one hoistway so as to cover each other in a non-contact manner.
Since multiple cars can be independently and safely operated in one hoistway and the amount of transportation per hoistway area can be increased, the total plane space of the hoistway can be reduced. Further, since the moving planes of the plurality of rope drive systems are made to intersect with each other, the moving lines of the three balancing weights 6a, 6b, 6c are arranged on the rear part of the car on substantially one plane in the X direction. The balance weights 6a, 6b.
The guide of 6c can be used also and can be made compact, and the device can be made small. Further, by disposing a plurality of rope drive systems in this way, the hoisting machine and the sheaves 4a, 4b, 4c are separated from each other and are easy to dispose.

Example 4. Hereinafter, an elevator apparatus according to a fourth embodiment of the present invention will be described with reference to the drawings. FIG. 8A is a perspective view schematically showing the elevator apparatus according to the fourth embodiment,
8B is a top view and FIG. 8C is a side view. In a hoistway, a plurality of inverted U-shaped rope drive systems are stacked so as to cover each other in a non-contact manner. In this embodiment, each of the moving planes formed by the inverted U-shapes of the three rope drive systems is It is configured to be substantially parallel to the Z axis and orthogonal to at least one of the moving planes. For example, in this embodiment, the moving plane of the rope drive system for the upper floors is the YZ plane, and the moving planes of the rope drive system for the middle floor and the lower floors are the XZ planes orthogonal to the YZ plane. Along with this, the place where the high-rise floor counterweight 6a moves is defined as the rear portion, and the middle-tier floor counterweight 6b and the low-rise floor counterweight 6c are arranged so that they move to the side. in this way,
By arranging the balancing weights separately on the rear surface and the side surface of the car 1, the main rope 2 can be arranged with a large margin, the rope drive system can be easily constructed, and the depth direction of the elevator apparatus can be made thin. In this embodiment, the moving plane of the rope drive system for the high floors is the YZ plane and the counterweight 6a for the high floors is arranged on the rear surface of the car 1. However, the present invention is not limited to this.
The moving plane of another rope drive system may be the YZ plane, and its counterweight 6 may be arranged on the rear surface of the car 1.

In the second and third embodiments, a cutout is provided at the rear of the lower car 1 so that the main ropes 2 connected to the lower car 1 can pass without coming into contact with the upper car 1. However, in this embodiment, as shown in FIG.
The two cars 1 have the same shape, and the connecting parts 16b and 16c are provided so that the connecting parts of the main ropes 2 of the middle floor car 1b and the lower floor car 1c project. For this reason, the main ropes 2 coupled to the lower car 1 can pass without contacting the upper car 1.

Also in this embodiment, as in the case of the first embodiment, a plurality of inverted U-shaped rope drive systems are constructed in one hoistway such that they are not in contact with each other. Each car can operate independently and safely and stably, and the amount of transportation per hoistway area can be increased, so that the total plane space of the hoistway can be reduced. Also, by arranging multiple rope drive systems like this,
The hoisting machine and the sheaves 4a, 4b, 4c are separated from each other and are easy to arrange.

Example 5. 9 is an enlarged perspective view showing a rear surface of a car 1 of an elevator apparatus according to a fifth embodiment of the present invention. In this embodiment, the connecting portion 1 is formed so that the connecting portion between the main rope 2 of the car 1b for the middle floor and the car 1c for the lower floor projects.
6b and 16c are provided. Further, the connecting portions 16b, 16
Since both c are provided on the rear surface of the car, the main ropes 2b, 2c
Are shifted in the X direction so that they do not touch. For this reason,
The main ropes 2 connected to the lower car 1 can pass without contacting the upper car 1.

Further, in the structure shown in FIG. 1, the lower car is displaced after the upper car in order to prevent the main ropes from contacting each other, but it may be displaced to the left and right. In addition, Example 2,
As shown in 3, at least a part of the upper car may be cut out, and when a plurality of cars arranged in the hoistway are projected on the XY plane, a part that connects at least the main ropes of the lower car. If it is configured so as to project from the car above, the same effect is obtained. Furthermore, a structure may be used in which a through passage is provided in the car so that the main ropes can pass near the center of the car.

Example 6. An elevator apparatus according to Embodiment 6 of the present invention will be described below with reference to the drawings. FIG. 10 is a configuration diagram showing an elevator apparatus according to the sixth embodiment. In the figure, 20 is a counterweight that also serves as a component of the linear motor, and 21 is a counterweight guide that also serves as a component of the linear motor. The counterweight 20 and the counterweight guide 21 constitute a motor, and the counterweight 20 is connected to the main rope 2. The other components are the same as those in FIG. 1, and in particular, in this embodiment, for example, the rope drive system for the middle floor and the rope drive system for the lower floor are composed of counterweights 20b, 20c and counterweight guides 21b, 21c. A linear motor is used.

Also in this embodiment, as in the case of the first embodiment, a plurality of inverted U-shaped rope drive systems are stacked in one hoistway so as to cover each other in a non-contact manner.
Since multiple cars can be independently and safely operated in one hoistway and the amount of transportation per hoistway area can be increased, the total plane space of the hoistway can be reduced. Further, in the first embodiment, when the hoisting machines 3a, 3b, 3c are arranged in the upper part, the size of the hoisting machine is large, and therefore, the machine room portion on the hoistway 7 in which the hoisting machine is placed becomes large. I will end up. On the other hand, if the linear motor is used, the parts that used the hoisting machines 3b and 3c and the sheaves 4b and 4c in the first embodiment can be changed to the deflecting wheels 5b and 5c, so that the size of the machine room can be reduced and the hoisting and lowering can be performed. The path 7 can be made smaller. In particular, it is effective in a configuration in which a plurality of rope drive systems are stacked.

Example 7. Hereinafter, an elevator apparatus according to a seventh embodiment of the present invention will be described with reference to the drawings. 11 and 1
2 is an explanatory view showing a part of one car in an enlarged manner. Since the main rope 2 in the conventional elevator apparatus can be arranged at the center of gravity of the car 1, even if the car 1 is pulled up by the main rope 2, no moment is generated. However, in the middle-layer and low-layer main ropes 2b and 2c of Examples 1 to 6, it may be necessary to eccentrically attach them to the car 1 in order to avoid the upper car 1a. When the main rope 2 is eccentrically attached to the car 1, a moment in the −θX direction as shown by an arrow A in FIG. Therefore, in this embodiment, a car inclination suppressing mechanism is provided to correct the moment due to eccentricity. For example, in FIG.
As shown in, a balance weight 22 for correcting the weight of the car 1 with respect to the position of the main rope 2 is provided.

When the car 1 is pulled up and down by pulling the main ropes 2, a moment in the -.theta.X direction as shown by an arrow A is generated, and the car 1 tends to incline. However, since the balance weight 22 is provided on the rear surface of the car 1, a moment corresponding to the weight of the balance weight 22 is generated in the direction B that cancels the moment A. Therefore, it is possible to suppress the inclination of the car 1.

Example 8. An elevator apparatus according to Embodiment 8 of the present invention will be described below with reference to the drawings. This embodiment is a modification of the car inclination suppressing mechanism, and FIG. 13 is an explanatory view showing an enlarged part of one car. Reference numeral 23 is a reinforced guide shoe that guides the car along the guide rail 8.
The guide rails 8 are arranged so as to intersect each other.
The guide shoes 23 are usually provided between the car 1 and the guide rails 8.
Is arranged at a position opposite to the moment generated when towing, and is strengthened to support the moment. That is, when the car 1 is moved up and down by the main ropes 2, -θX
Since a directional moment A is generated, reinforced guide shoes 23 are provided at the upper left and lower right so as to support the moment A. Therefore, the guide shoe 23 can support the moment A due to the eccentricity and suppress the inclination of the car 1.
Moreover, the existing guide shoe may be provided as it is, if necessary.

Example 9. An elevator apparatus according to Embodiment 9 of the present invention will be described below with reference to the drawings. This embodiment is a modification of the car inclination suppressing mechanism, and FIG. 14 is an explanatory view showing an enlarged part of one car. 25 is a moment compensation link, for example, a parallel link. That is, parallel 4
It uses a combination of four-section links using edges. In this method, 25a to 25g form a two-stage four-joint link, and the left pin portions 26a and 26b are joined together with a cage, and the right pin portions are fitted with guide shoes 23a and 23b. And is in contact with the guide rail 8 which is a fixed part. A guide shoe 23c coupled to the car 1 is provided on the opposite side of the parallel link 25 with the guide rail 8 interposed therebetween. This guide shoe 23
Similarly to the eighth embodiment, a, 23b, and 23c are also arranged at positions facing the moment generated when the vehicle is pulled, and are strengthened to support the moment.

With this configuration, the moment force A
Therefore, even if the car 1 is inclined, the parallel link 25 maintains the parallelism. Therefore, the tilting force is converted into the pressing force to the guide rail 8 via the guide shoes 23a and 23b. Therefore, if this is the case, the car 1 is -Y
The guide shoe 2
It is supported not to move at 3c. Thus, the parallel link 25 constitutes a car inclination preventing mechanism, and the main rope 2 and the car 1
Even if the joint part of is eccentric with respect to the center of gravity of the car 1, the car 1 can be stably moved up and down without inclining.
Further, since the moment compensation link 24 can be realized with a light weight, it is suitable for practical use.

Further, the guide shoe 23 as in the eighth embodiment.
The guide rail 8
Then, the moment force A is applied to the building, and the force is further applied to the building fixing it through the guide rail 8. However, with the configuration of this embodiment, since the pressing force of the guide shoes 23a and 23b against the guide rail 8 is supported by the guide shoe 23c arranged therebetween, the twisting force acts on the guide rail 8. Without doing so, the influence on the building supporting the guide rail 8 can be reduced. In addition, traveling is stable. Moreover, in the eighth embodiment, since the inclination of the car 1 is determined by the positional accuracy of the guide shoes 23 that sandwich the guide rail 8, a high positional accuracy is required for mounting the guide shoes 23, but according to this embodiment, ,
The link mechanism is capable of contracting in the parallel direction (Y direction) and is supported by the guide shoes 25c, which does not require high mechanical precision and can reduce costs.

Example 10. Hereinafter, Example 10 of the present invention
The elevator apparatus according to FIG. This embodiment is a modification of the car inclination suppressing mechanism, and FIG. 15 is an explanatory view showing an enlarged part of one car. Reference numeral 25 is a moment compensation link, for example, an X link. That is, the two rod portions 25a and 25b form an X-link, the pin 26a is coupled to the car 1, and the pin 26b is fixed in the Y direction by the long hole 27 provided in the car 1, and the Z direction. It is fixed so that it can move freely. Guide shoes 23a and 23b are attached to the pin portion on the right side and are in contact with the guide rail 8. A guide shoe 23c coupled to the car 1 is provided on the opposite side of the guide rail 8.

With this structure, as in the ninth embodiment, even if the car 1 is inclined by the moment force A, X
The link 25 keeps the parallelism, and the tilting force is converted into a pressing force to the guide rail 8 via the guide shoes 23a and 23b. Therefore, if this is the case 1
Tries to move in parallel in the -Y direction, but supports it by the guide shoe 23c so as not to move.

With this structure, as in the ninth embodiment, X
The link 25 constitutes a car inclination preventing mechanism, and even if the connecting portion between the main rope 2 and the car 1 is eccentric with respect to the center of gravity of the car 1, the car 1 can be stably moved up and down without inclining. Further, since the guide rail 8 is not subjected to a twisting force, the influence on the building supporting the guide rail 8 can be reduced, and the machine accuracy can be reduced. Further, since the number of parts of the link mechanism is smaller than that of the ninth embodiment, the cost can be reduced.

The car 1b and the counterweight 6b are guide shoes (not shown) provided on the car 1b and the counterweight 6b, respectively.
The car 1b is vertically guided along the guide rail 8 by being guided to the guide rail 8 via the guide rail 8. At this time, the two main ropes 2b are joined on both side surfaces of the car 1b, and the two hoisting machines 3b are driven by a control device (not shown) so as to move up and down in a balanced manner in the X direction. Control. The same applies to the car 1c for lower floors. Since the car 1 is towed by the two main ropes 2 as described above, the moment due to the eccentricity can be minimized as compared with the case where the car 1 is towed by the single main rope 2.

In the above embodiment, the hoisting machine 3 is used as the main rope 2
However, the present invention is not limited to this, and it is also possible to configure one hoisting machine for the main ropes 2b for middle floors on both sides. The same applies to hoisting machines for lower floors. Further, the car 1 may be towed not only by the two main ropes 2 but also by, for example, four. Also in this embodiment, as in the first embodiment, a plurality of inverted U-shaped rope drive systems are stacked in one hoistway so that they can be lifted up and down without contacting each other. Since each car can operate independently and safely and stably, and the transportation amount per hoistway area can be increased, the total plane space of the hoistway can be reduced.

Example 12. FIG. 18 is an enlarged perspective view showing portions of the cars 1b and 1c according to the twelfth embodiment. In the eleventh embodiment, the main ropes for middle floor 2b and the main ropes for lower floor 2c are displaced in the Y direction so as not to interfere with each other during the ascending / descending movement, so that the center of gravity cannot be completely raised. On the other hand, in this embodiment, as shown in the figure, the connecting portion of the main ropes 2c for lower floors and the car 1c is made wider in the X direction than the connecting portion of the main ropes 2b for middle floors and the car 1b. is doing.
And the main ropes 2b and 2c are on both sides of the cars 1b and 1c,
In the X direction, they are connected on a line passing through the centers of gravity Gb and Gc of the cars 1b and 1c. The configurations of the other parts are the same as in the eleventh embodiment. As described above, by disposing the two pulling points so as to pass through the center of gravity of the car 1, the center of gravity can be raised more than in the eleventh embodiment.

Example 13 FIG. 19 is an enlarged perspective view showing portions of the cars 1b and 1c according to the thirteenth embodiment. In this embodiment, as shown in the drawing, the main ropes 2b for the middle floor are joined at two diagonal positions in the Y direction on both sides of the car 1b, and the joining position is the center of gravity Gb of the car 1b. It is on the line passing through. Similarly, the main ropes for lower floors 2c are joined on both sides of the car 1c at diagonal positions in the Y direction, and the joining position is on a line passing through the center of gravity Gb of the car 1c. Furthermore, the connecting parts for the middle floor and the connecting parts for the lower floor are offset from each other. The configurations of the other parts are the same as in the eleventh embodiment. According to this structure, as in the twelfth embodiment, the two hoisting points are arranged so as to pass through the center of gravity of the car 1, the center of gravity can be hoisted, and an elevator apparatus that can stably raise and lower the car can be obtained.

Example 14 FIG. 20 shows the first embodiment of the present invention.
It is a side view which shows the elevator apparatus concerning 4th typically.
In the figure, the rope drive system for high floors has the same structure as that in the first embodiment. The rope drive system for the middle floor constitutes a 2: 1 roping in which the main ropes 2b are turned under the car 1b and the car 1b is supported from below by the deflecting wheels 5b from both sides. A rope drive system is not configured for the lower-floor car 1c, and a hydraulic elevator 28 that hydraulically lifts the car 1c from below is used.

The rope drive system for the middle floor in this embodiment shows another embodiment in which the main ropes 2 are supported on both sides of the car 1. In this way, if the main rope 2b is turned below the car 1b and supported from below on both sides of the car 1b, it can be driven without generating a moment.
Furthermore, since the lower-level floor car 1c is configured by using a hydraulic elevator that is hydraulically lifted, the higher-level car 1c
There is no interference between the car 1b for the middle floor and the rope drive system for the lower floors, and the structure is simple. Further, the center of gravity of the cars 1a and 1b on the upper floors and the middle floors can be raised more easily than in the eleventh embodiment.

Also in this embodiment, the inverted U-shaped rope drive system for the upper floors and the U for the middle floors are provided in one hoistway.
The V-shaped rope drive system and the hydraulic drive system for lower floors are configured so that they can be raised and lowered without contacting each other, and multiple cars can be independently and safely stabilized in one hoistway. Since it can be operated and the roving is simple, the hoistway can be made small, and the transport amount per hoistway area can be increased, so that the total plane space of the hoistway can be reduced.

In the above embodiment, the inverted U-shaped rope drive system, the U-shaped rope dive system and the hydraulic type are used, but the present invention is not limited to this, and other types such as linear motor drive system are also used. You may comprise in combination.

Example 15 In the first embodiment, in operation, on the first floor or the standard boarding floor, the lower car waits underneath until the loading of the cars above the plurality of cars is completed. Then, as soon as the loading of the upper car is completed, the car immediately below it operates to move to the boarding floor. FIG. 21 shows that when the elevator apparatus according to the fifteenth embodiment is in operation,

This is the floor for boarding the lower floor car 1c.

As shown in the figure, a plurality of boarding floors are provided on the first floor or the standard boarding floor, and they are connected to each other by, for example, stairs. Passengers can board the car from the car loading floor that corresponds to the desired floor. In this case 3
You can start boarding one car at the same time, and when you finish boarding the three cars, you can start operating three cars at the same time. Therefore, as in the case of the operation in the first embodiment shown in FIG. 3, at t2, waiting for the passenger to board the middle floor car 1b, or t
In 3, it is not necessary to wait for getting on the lower floor car 1c, and the multi-transport efficiency can be further improved. In this embodiment, a plurality of floors are connected to each other by stairs on the first floor and the standard boarding floor. However, the present invention is not limited to this, and it is possible to board a plurality of cars at the same time. do it.

Example 16 Hereinafter, Example 16 of the present invention
The elevator apparatus according to FIG. The present invention includes a plurality of cars in one hoistway, and the cars can be independently moved. When operating a car with such a configuration, it is necessary to take safety measures that were not necessary in the past. This embodiment is for safe operation. FIG. 22 is a flowchart showing an example of control at the start of moving the car according to the sixteenth embodiment. This control can be executed by, for example, a control device that controls the hoisting machine 3.

First, in step ST1, it is determined whether or not there is another car 1 in the moving direction of the car to be controlled. If there is no other car 1, the movement of the car to be controlled is started in step ST4. If there is another car in the moving direction in the determination in step ST1, it is determined in step ST2 whether the distance between the car and the car to be controlled is within a certain distance. The distance between the cars can be known from the operating states of the hoisting machine controlled by the controller and the hoisting machines of other cars. In addition, the constant distance is a safe distance even if the car to be controlled starts moving, and various cases can be considered depending on the moving speed. It is set to about the braking distance.

If the distance between the cars is larger than a certain distance in step ST2, it is considered safe to start the movement, and the movement of the car to be controlled is started in step ST4. When the distance between the cars is within a certain distance in step ST2, the time is waited in step ST3, and the determination is repeated in step ST2. In this way, it is determined whether or not the car may be moved before the car starts moving, and control is performed so that the car does not start moving when the distance between other cars in the car moving direction is less than a certain distance. Therefore, even if a plurality of cars are provided in one hoistway, the elevator can be operated safely and an elevator device with high transportation efficiency can be obtained.

Example 17 Hereinafter, Example 17 of the present invention
The elevator apparatus according to FIG. Similar to the sixteenth embodiment, this embodiment is for avoiding collision between cars and for operating safely. FIG. 23 is a car 1a for the upper floors and a car 1b for the middle floors of the elevator apparatus according to the seventeenth embodiment.
It is a perspective view which expands and shows. In the figure, reference numeral 30 is a distance measuring device that measures the distance between the cars without contact with, for example, a laser.

The distance measuring device 30 is provided on the car 1b for the middle floor, emits the laser beam upward, receives the laser beam reflected by the car 1a for the upper floor above, and detects the time difference between them. It measures distance. In the sixteenth embodiment, the distance between the cars is obtained by calculating the information from the hoisting machine by the control device, and the safe operation is controlled based on this value.
In this embodiment, the distance between the cars is further measured by the distance measuring device 30.
To measure. Using both of these values, the safety at the start of moving the car is monitored based on the flowchart of FIG. Since the distance measuring device 30 is provided to actually measure the distance between the cars, reliability is enhanced rather than relying only on the value calculated by the control device. In the above embodiment, the distance measuring device 30 uses a laser, but the distance measuring device 30 is not limited to this. For example, a device that measures a distance using ultrasonic waves or magnetism may be used. Further, instead of the non-contact distance measuring device, a direct distance measuring means for connecting the cars with a wire may be used. Further, the guide rail 8 or the hoistway 7 may be provided with a linear scale.

Example 18. Hereinafter, Example 18 of the present invention
The control method of the elevator apparatus according to FIG. In this embodiment, in order to safely operate an elevator apparatus provided with a plurality of cars in one hoistway, the moving speed of the corresponding car 1 is controlled according to the distance between adjacent cars 1 or the relative speed. is there. As shown in the sixteenth embodiment, the distance between the cars 1 and the relative speed can be calculated and obtained by the control device from the information of the hoisting machine or can be obtained and measured by the distance measuring device 30 provided in the car.

FIG. 24 is a flow chart showing an example of control at this time. In normal operation, a speed pattern of acceleration / constant speed / deceleration is set in advance as the rated traveling speed of the car 1. Arbor 1 starts moving, step ST11
Start rated driving with. Hoisting machine 4 in step ST12
Calculate the car distance between adjacent cars from the hoisted state.
Further, in step ST13, the relative speed between the adjacent cars is calculated from the hoisting state of the hoisting machine 4. Based on this relative speed between cars, a safe distance between cars is calculated even at that relative speed (step ST14).

Next, in step ST15, the actual inter-car distance obtained in step ST12 and step ST14
The safety distances from the relative speeds obtained in step 1 are compared, and if the actual distance between the cars is large, the rated travel is commanded in step ST16. The safety distance from the relative speed obtained in step ST14 is compared, and if the actual inter-car distance is small or equal, it is determined to be dangerous, and the car is decelerated so that the relative speed becomes small in step ST17.

In the above embodiment, the distance between the cars and the relative speed between the cars are calculated from the hoisting condition of the hoist, but the present invention is not limited to this.
The same effect can be obtained by using a sensor such as a speedometer. In this embodiment, the moving speed of the car is controlled according to both the distance between the adjacent cars and the relative speed thereof, but the movement of the car according to either of the distance between the adjacent cars and the relative speed thereof. It may be configured to control the speed. As described above, since the moving speed of the corresponding car 1 is controlled according to the distance between the adjacent cars 1 and the relative speed,
Even if a plurality of cars are provided in one hoistway, the elevator device can be operated safely. In particular, although the vehicle runs at the rated speed in the normal operation, even if the distance between the adjacent cars is shortened or the speed of the car becomes abnormal due to some cause during the operation, according to this embodiment, By controlling the moving speed, it is possible to operate safely and efficiently.

Example 19 Hereinafter, Example 19 of the present invention
A control method for the elevator apparatus according to the above will be described. As shown in the sixteenth embodiment, the distance between the cages can be calculated and obtained by the control device from the information of the hoisting machine, or can be obtained by measuring with the distance measuring device 30. Using this inter-car distance, the safety at the start of car movement is monitored based on the flowchart of FIG. In this embodiment, not only at the time of starting the movement of the car, but for example, when the distance between the cars approaches a distance that is dangerous considering the braking force of the car during operation, for example, the mode is switched to the emergency operation mode for control. .

FIG. 25 is a flow chart showing an example of the control at this time. In step ST31, for example, the distance of the upper car is detected by the control device or the distance measuring device 30. In step ST32, it is determined whether the car distance is within a certain distance. The constant distance at this time is a distance in which the distance between the cars is dangerous considering the braking force of the cars, and for example, the height of the cars is set. If it is determined that the distance is equal to or more than the predetermined distance, it is within the safe range, and the operation is continued in step ST33.

If the distance is within a certain distance in the judgment of step ST32, it is regarded as a dangerous range, and the operation mode is switched to the emergency operation mode. That is, in step ST34, both cars are urgently decelerated,
If there is a shelter nearby, shelter it (step ST3).
5, 36). If there is no shelter nearby, step ST
At 37, since the danger cannot be avoided and it is an emergency, the operation of all the cars is stopped. It is also possible to resume normal operation when the danger is avoided in the case of evacuation.

According to this embodiment, in a vehicle having a plurality of cars in one hoistway, even if the distance between the cars approaches a dangerous distance for some reason, the danger can be avoided and the safety can be improved. There is an effect that an elevator device with high property can be obtained.

The control method of the elevator apparatus according to FIG. 26: is a perspective view which expands and shows the car 1a for high floors and the car 1b for middle floors of the elevator apparatus by Example 20. As shown in FIG.
In the figure, reference numeral 32 denotes a car proximity detector having a sensor at the tip, for example, a rod of several meters, and mechanically detects that another car is approaching. The car proximity detector may be a system in which one car is provided with a sensor, the other car is provided with a fin extending a few meters above or below, and the fin enters the sensor to perform detection. Alternatively, a method of operating a limit switch as in the conventional pit section may be used. The distance between the cars can be known from the operating states of the hoisting machine controlled by the control device and the hoisting machines of other cars, but for further safety, distance measurement is performed in this embodiment. A container 30 and a car proximity detector 32 are provided.

Since the distance measuring device 30 has been described in the seventeenth embodiment, the car proximity detector 32 will be described here. The safety is monitored by controlling the distance between the cars. In this embodiment, the control by the control device becomes abnormal and the control cannot be performed. Distance measuring device 3
When the output of 0 becomes unreliable, the car proximity detector 3

In the figure, 33 is a disc brake that operates on the hoisting machine 4, and 34 is an emergency stop provided between the car 1 and the guide rail 8.

In this embodiment, two emergency stop mechanisms, a disc brake 33 and an emergency stop 34, are provided. When mechanically detecting that the other car 1 is approaching, the disc brake 33 interlocks with this and forcibly stops the rotation of the hoisting machine 4, and stops the car 1. Further, the emergency stop 34 fixed to the car 1 is connected to the guide rail 8 by grasping the guide rail 8 and stops the movement of the car 1.

According to this embodiment, in a car having a plurality of cars in one hoistway, even if the distance between the cars approaches a dangerous distance for some reason, the cars are stopped to avoid the danger. It is possible to obtain an elevator device with high safety. In this embodiment, two emergency stop mechanisms of the disc brake 33 and the emergency stop 34 are provided, but either one may be provided.

In the first to the twentieth embodiments, the operation system has been described in which the entire ascending / descending process of the hoistway is divided into a plurality of zones and the cars are assigned and serviced. However, the present invention is not limited to this. It may be an operation method such as a lobby method, or may be an operation method that operates according to a call without specifying a service method. In addition, although examples 16 to 20 have been described for improving safety reliability, these safety devices may be any of the above, may be provided in combination, or may be omitted.

Example 21. Hereinafter, Example 21 of the present invention
The elevator apparatus according to FIG. 28,
FIG. 29 is a side view schematically showing an elevator apparatus according to Example 21. In the first embodiment, the rope drive system for the upper floors has the folding position of the main rope 2a arranged at a position where the hoistway can be moved in the entire hoisting stroke, and the other rope drive systems can move a part of the whole hoisting stroke. Main rope 2 in position
Although the folding positions of b and 2c are arranged, in this embodiment, the folding positions of the main ropes 2a, 2b and 2c are arranged at positions where all rope drive systems can move in the entire ascending and descending strokes of the hoistway. There is.

In the zone service operation system as in the first embodiment, the moving range of the car 1 is fixed, and the car 1 must be selected according to the desired floor. On the other hand, according to the configuration of this embodiment, when a passenger gets on the car, he / she can independently move in a range where all of the plurality of cars 1 do not come into contact with the upper and lower cars 1 in response to the passenger's request. You can In the first embodiment, the hoisting machine 3, the sheave 4, the deflector 5
There must be a machine room to store the
With this configuration, all can be stored in one machine room.

In FIG. 28, when the inverted U-shaped rope drive system is projected onto the YZ plane, the inverted U-shaped rope drive system is constructed so as to overlap with each other in the ascending / descending direction in a non-contact manner. When the plane composed of the drive system is a moving plane, an example is shown in which the moving planes of the plurality of rope drive systems are configured to be substantially the same plane. Further, FIG. 29 shows an example of a configuration in which each of the moving planes of the plurality of rope drive systems is substantially parallel to the Z axis and each of the moving planes is substantially orthogonal to at least one of the other moving planes. . In this way, in both configurations, the folding positions of the main ropes 2a, 2b, 2c are arranged so that all rope drive systems can move in the entire ascending / descending stroke of the hoistway.

Example 22. Hereinafter, Example 22 of the present invention
The elevator apparatus according to FIG. FIG. 30 is a side view schematically showing an elevator apparatus according to Example 22. In this embodiment, the entire hoisting stroke of one hoistway 7 is performed in a plurality of zones, for example, a high floor (FH) and a middle floor (FH).
M) and lower floors (FL) are divided into three zones, and the moving ranges of the plurality of cars housed in the hoistway are assigned from the top of the zone in order from the one located at the top. That is, the high floor car 1a moves in the high floor zone (FH), the middle floor car 1b moves in the middle floor zone (FM), and the low floor car 1c moves in the low floor zone (FL).

As described above, in the zone service operation system in which only a part of the entire ascending / descending stroke is stopped when requested, and the other floors are not stopped, the plurality of cars 1 accommodated in one hoistway are not stopped. The upper floor of the zone divided from the car 1 located above is served. Also,
As shown in the figure, two hoistways 7 are provided to connect the high-rise floor cars 1a, the mid-rise floor cars 1b, and the low-rise floor cars 1c, and use one of the cars as a counterweight for the other car. is doing. In addition, the hoisting machine 3, the sheave 4, the deflector 5
Is shared for each zone. Of course, as in the conventional case, a system having one hoistway and a counterweight may be provided.

When the service areas of the cars 1 are completely divided in this way, there is an effect that an elevator device that is safe and has a simple structure can be obtained without the risk of cars coming close to each other abnormally.

Example 23. Hereinafter, Example 23 of the present invention
The elevator apparatus according to FIG. FIG. 31 is an explanatory diagram for explaining a floor call button in operation of the elevator apparatus according to the twenty-third embodiment. In this operation system, as shown in FIG. 28, the configuration of each car 1 is configured so as to be able to go up and down in the entire stroke of the hoistway, and all the hoisting machines 3, sheaves 4 and deflecting wheels 5 are provided in one machine room. Stored in M. The operation system uses the zone service system, and the upper floor car 1a covers the upper floors (FH) of 21F to 30F, and the middle floor car 1b covers the upper floors (FH) of 11F to 20F. In the low-rise floor car 1c, the low-rise floor (FL) range of 1F to 10F is targeted. The standard boarding floor (FI) is 1F. In addition, in the figure, (a) shows a configuration example of floor call buttons of 21F to 30F, (b) shows a configuration example of floor call buttons of 11F to 20F, and (c) shows a configuration example of floor call buttons of 2F to 10F. The number corresponding to the floor is written in □.
For example, on the floor call button of 25F, 26F is written in □ of Δ for instructing to go up, and 24F is written in □ of ▽ for instructing to go down.

In many cases, the call buttons on each floor of the conventional elevator apparatus have only buttons indicating up and down. However, as in the present invention, when a plurality of cars are operated in one hoistway and, for example, the zone service system is used, it is difficult to allocate cars without knowing which zone above or below the car is desired. Therefore, it is efficient to arrange call buttons for each zone on the call buttons on each floor as shown in a, b, and c in FIG. 31 so that passengers can press the button for their own target zone. You can operate the basket.

Further, if a call button for the first floor (FI), which is considered to be used particularly frequently, is provided on this call button, the operation can be more efficiently performed. This button may be able to press all floors. Further, the service zones of each car 1 may be configured to overlap at least one floor so that the passengers can transfer to each zone. For example, 21F
May allow both mid-level and high-level cars to be stopped. In addition, as a service when people on the upper floors want to go to the lower floors and vice versa, it is possible to stop at least part of the lower floors while the high car is descending, You may be able to rise.

In the above elevator apparatus, a space for storing the car 1 may be provided below the first floor or the standard boarding floor. If this space is provided below the hoistway 7,
Easy to configure. Also, if a plurality of hoistways 7 are provided, they can be used as an emergency shelter during operation. Further, the plurality of cars 1 provided in one hoistway 7 is not limited to three, and may be two or three or more. Further, although the hoisting machine 3 and the counterweight 6 are provided on each car 1, any one of them may be combined. Further, although the structure in which the hoisting machine 3, the sheave 4, and the main measure 2 constitute the driving means has been mainly described, a system using a linear motor as shown in FIG. The method may be used. Further, the main measure 2 may be a chain instead of the wire rope, or other transmission means. Also, basket 1
Can be sheltered from the hoistway 7, and the lower car 1 can be the upper car 1
By providing a mechanism that can overtake passengers, the operating efficiency can be further improved. Furthermore, in Examples 1 to 23, only one car 1 is provided at a place where one operation is performed, but two cars may be connected in series like a double deck. That is, in FIG. 1, it can be constituted by three places × 2 = 6 cars, which further increases the transportation amount. Of course, two or more may be used, or only a part may be a double deck.

The elevator apparatus constructed as in Examples 1 to 23 can be constructed with almost no change in the components of the conventional elevator apparatus, and a large number of personnel can be transported in a narrow elevator installation area. Also, since different floors can be serviced by multiple cars, it is possible to provide almost the same service as before even when transporting a large quantity. Therefore, in a building requiring a large amount of transportation capacity such as a high-rise building, the elevator installation area can be reduced without lowering the transportation service, and the floor area of the building can be effectively used.

Example 24. Hereinafter, Example 24 of the present invention
The elevator apparatus according to FIG. 32,
33 is a side view schematically showing an elevator apparatus according to Example 24. FIG. The elevator apparatus according to Examples 1 to 23 is called 1: 1 roping, and is a roping method in which the balance weight moves 1 time when the car moves 1 time. In this embodiment, as another roping method, an embodiment relating to an elevator apparatus using 2: 1 roping in which one side of a main rope is connected to a fixed end as shown in FIG. 47 will be described. In this system, the car moves 1/2 of the movement of the main rope 1.

FIG. 32 shows a state in which a car is loaded,
FIG. 33 shows a state in which the car stops at the upper floor. In the figure, FI is the boarding floor, and FS1 and FS2 are F
Floors higher than I, for example, lower floors and middle floors. One end 2a of the main rope 2 is connected to the fixed portion, and the other end 2b is connected to the counterweight 6 via the sheave 4. First basket 1a
Are directly connected to the main rope 2. Further, the second car 1b is indirectly hung down to the main rope 2 via the deflecting wheel 5.

As shown in the figure, from the state where the first car 1a is fixed to the boarding floor FI, the sheave 4 is driven by the hoisting machine 3.
When is rotated, power is transmitted to the main rope 2 by traction, and the cars 1a and 1b rise. For example, as shown by arrow A in FIG. 33, when the second car 1b is moved from the boarding floor FI to the lower floor FS1, the first car 1a is moved to the arrow B.
Move from the boarding floor FI to the middle floor FS2 as shown in FIG. That is, while the second car 1b moves by 1, the first car 1a moves by 2. In this way, if one end of the main rope 2 is fixed and the second car 1b is connected to the main rope 2 via the wheel 5, the first car 1a and the first cage 1a directly connected to the main rope 2 are connected. Hoisting machine 3 with 2 baskets 1b
The ascending / descending distance is different.

As described above, in this embodiment, two cars 1a and 1b can be simultaneously driven by one hoistway, and the two cars 1a and 1b are driven by one drive motor. Can serve different floors. For this reason,
A single hoistway can carry a large number of passengers and lower floors FS1,
The middle floor FS2 can be used as a sky lobby floor of a high-rise building or the like, and can be used as a shuttle elevator that makes a direct round trip to the sky lobby floor. Further, the conventional elevator apparatus can be constructed with almost no change in its components, and a large number of personnel can be transported in a small elevator installation area. Also, since one hoist can service multiple floors with different baskets, it can be serviced more efficiently than conventional double-deck elevators. In addition, if you use multiple hoisting machines, the degree of freedom of each car will increase and service will be further improved. Therefore, in a building that requires a large amount of transportation capacity such as a high-rise building, the elevator installation area can be reduced without lowering the transportation service, and the floor area of the building can be effectively used.

In this embodiment, a system using 2: 1 roping is used and three cars are provided. The second car 1b and the fixed portion are connected to each other by the second main rope 2c, and the third car 1c is indirectly suspended from the second main rope 2c via the deflecting wheel 5. Other configurations are similar to those in FIG.

Similar to the twenty-fourth embodiment, when the sheave 4 is rotated by the hoisting machine 3 from the state where the first car 1a is fixed to the boarding floor FI, power is transmitted to the main ropes 2 by traction, and the car 1a, 1b, 1c rise. For example, when the second car 1b is moved from the boarding floor FI to the lower floor FS1, the first car 1a moves from the boarding floor FI to the higher floor FS.
Moving to 3, the third car 1c moves from the boarding floor FI to the lower floor FS0. This lower floor FS0 is a boarding floor FI
To the lower floor FS1 are the central floors. That is, when the first car 1a moves 1 time, the second car 1b moves 1/2, and the third car 1c moves 1/4. In this way, one end of the main rope 2 is fixed, the second cage 1b is joined to the main rope 2 via the deflecting wheel 5, and the second cage 1b is further connected.
If the third car 1c is connected through the baffle wheel 5, the first car 1a and the second car 1 directly connected to the main ropes 2 will be described.
The hoisting distance by the hoisting machine 3 is different between b and the third car 1c.

According to this embodiment, the same effect as that of the twenty-fourth embodiment is obtained, and further three cars are provided as compared with the two cars, so that the transportation amount can be further improved. It is also possible to combine more cars in the same way.

The elevator apparatus according to FIG. 35: is a side view which shows the elevator apparatus by Example 26 typically. In the figure, 3b is a hoisting machine, which is arranged at a portion which is the fixed end 2a of FIG. Boarding floor FI
When the sheave 4a is rotated by the hoisting machine 3a from the state where the first car 1a is fixed, the power is transmitted to the main rope 2 by the traction, and the cars 1a and 1b rise. For example, when the second car 1b is moved from the boarding floor FI to the lower floor FS1, the first car 1a moves from the boarding floor FI to the middle floor FS2. When the sheave 4b is further rotated, the second car 1b can be moved to any position between the lower floor FS1 and the middle floor FS2.

In this way, the hoisting machine 3a,
If 3b is provided and the second car 1b is coupled to the main rope 2 via the deflecting wheel 5, the hoisting is performed by the first cage 1a and the second cage 1b directly coupled to the main rope 2. The ascending / descending distances of the machines 3a and 3b are different. In the case shown in FIG. 32, the moving distance of the car 1a is determined by the hoisting machine 4 and the car 1b can move only half the stroke, but in this embodiment, the car 1a
b can also be moved separately. In this way, although the number of drive motors is increased, the degree of freedom of the car 1b is increased.

Example 27. Hereinafter, Example 27 of the present invention

The operation of the cars 1a and 1b thus constructed will be described. The second car 1b moves by the same distance as the first car 1a moves up and down by the hoisting machine 3a. Further, the second car 1b can be independently moved up and down by the hoist 3b. In this way, the first car 1a and the second car 1b, which are directly connected to the main ropes 2, can obtain different lifting distances. Therefore, the same effect as that of Example 26 is obtained.

Note that in Examples 24 to 27, only one car is provided in a place where one operation is performed, but two cars are connected like a double deck, that is, in FIG. 32, 2 cars × 2 = 4. It may be a system composed of individual baskets. Further, two or more cars may be provided at the place where one operation is performed.

Example 29. Hereinafter, Example 29 of the present invention
The elevator apparatus according to FIG. 38 is a side view schematically showing an elevator apparatus according to Example 29. As shown in FIG. In the configuration of the elevator apparatus described in the above Examples 1 to 28, the car moves up and down in the hoistway, and the main rope was reciprocating, but in this embodiment, the ring-shaped main rope is rotated. It is configured to let the basket circulate. In the figure, 1a to 1h are circulating cars, for example, 8 cages, 2a is a main rope that goes around the high-rise section, 2b is a main rope that goes around the middle-rise section, 2c is a main rope that goes around the low-rise section, and 3a is a high-rise section main A hoisting machine for ropes, 3b is a hoisting machine for middle-layer main ropes, 3c is a hoisting machine for low-rise main ropes, 4a is a sheave for high-rise main ropes, 4

5a is a deflector wheel for high-rise main ropes, 5b is a deflector wheel for mid-rise main ropes, 5c is a deflector wheel for low-rise main ropes, 7A is an ascending path for raising the car 1, and 7B is for descending the car 1. Downhill, 10
a, 10b, 10c are provided on the lower deflecting wheels of the main ropes 2a, 2b, 2c, and 11a to 11h are provided on the cages 1a to 1h, respectively. It is a gripping mechanism. Further, 12a is an upper car lateral movement mechanism, 12b is a lower car lateral movement mechanism, and
Are loops A and LB formed by the rope drive system on the upper floors
Is loop B, LC formed by the rope drive system on the middle floor
Is a loop C formed by the rope drive system on the lower floor. The arrow U indicates the ascending direction of the car, and the arrow D indicates the descending direction of the car.

The structure of the elevator apparatus according to this embodiment will be described below with reference to the drawings. In loop A (LA), the cages 1g and 1e are the main rope 2a and the rope gripping change mechanism 11g,
They are connected and balanced through 11e. Also, loop B
In (LB), the cars 1h and 1d are connected and balanced with the main rope 2b via the rope grip change mechanisms 11h and 11d. Further, in the loop C (LC), the cars 1a and 1c are connected to the main rope 2c via the rope grip change mechanisms 11a and 11c and are in balance with each other. Further, the cars 1b and 1f are connected to the moving ropes of the lateral movement mechanisms 12a and 12b via the rope grip change mechanisms 11b and 11f, respectively.

Next, the operation of this embodiment will be described. In the loop C (LC), the car 1a is lifted in the U direction by the sheave 4c by the driving force of the hoist 3c, and at the same time,
The car 1c balanced with the car 1a descends in the D direction. Almost in synchronization with this movement, the car 1h and the car 1d move in the loop B (LB), and the car 1g and the car 1e move in the loop A (LA). During this vertical movement, the car 1b is laterally moved from the descending direction to the ascending direction by the lateral moving mechanism 12b. Along with this, the car 1f is moved laterally 12
By a, it moves laterally from the ascending direction to the descending direction. That is,
Each of the cars 1b and 1f laterally moves in the direction opposite to the direction in which the cars have been moved so far.

When the car 1a reaches the stop floor (FS1), the car 1a stops and the passengers get on and off. During this time, the rope gripping change mechanism 11a of the car 1a operates and grips the rope from the low-layer main rope 2c to the middle-layer main rope 2b. Similarly, basket 1
h, 1e, and 1d stop at the stop floor, and at the same time, the rope is grabbed and changed to the next main rope 2. At this time, basket 1c, basket 1g
Arrive at the getting-off floor (FI) and the top floor (FS3) respectively, and at the same time when the passengers get off, the rope gripping mechanism 11
c and 11g operate to grab the main rope 2c and the main rope 2a and move them to the moving ropes of the car lateral movement mechanisms 12b and 12a. Next, the cars 1b and 1f that have completed the lateral movement grip the main ropes 2c and 2a from the rope for lateral movement and change the grip.

In this way, a plurality of ring-shaped main ropes that circulate a part of the ascending / descending stroke are provided, a part of these are crossed, and one pair of cars is connected to one main rope in a balanced manner. The car moves up and down while grasping the main rope by repeatedly attaching and detaching it. Therefore, many cars can be operated under a load similar to the conventional load, a large amount of transportation can be obtained with a small installation area, low cost can be configured, and safe operation can be achieved. In particular,
Compared with the conventional ring-shaped elevator device shown in FIG.
Since the number of cars 1 connected to one main rope 2 can be reduced,
It is possible to prevent a large load from being applied to the main rope and the hoisting machine.

Further, in this embodiment, in one rope drive system, the cages of substantially balanced weights are attached to and detached from the main ropes thereof substantially in synchronization, so that a counterweight is not necessary and the structure becomes complicated. And a safe elevator device can be obtained. In addition, since all the cars 1 are attached to and detached from the main ropes 2 almost at the same time, it is possible to prevent the balance from being lost, keep the distance between the cars 1 constant, and obtain a safe elevator device. Also, in this example,
Eight cages 1 are provided, and the number of cages is not limited to this, but if at least twice the number of main ropes 2 is provided, one pair of cages 1 can be provided by one ring-shaped rope drive system. Can be combined. For example, when the number of passengers during the daytime is small, the number of cars may be the minimum number (the number of main ropes × 2), and when the number of passengers is high in the morning and evening, more cars may be combined. Further, in this embodiment, three ring-shaped rope drive systems are provided, but the number is not limited to this, and any number may be configured.

The operation system of the elevator apparatus of this embodiment will be described below. In this embodiment, three ring-shaped rope drive systems consist of a high floor (FH) and a middle floor (FH).
M) and lower floors (FL) are divided into each zone to be serviced. FIG. 39 is an explanatory diagram showing an example of an operation system when the zoning service according to this embodiment is performed.

The operation procedure is shown below. t1 (mode 1 to mode 2): car A is in the express operation,
Stop at FS1, open the door and let the passenger get off on the way,
Grab the rope from the main ropes 2c to 2b and close the door. : The car B moves laterally, opens the door to allow the user to get in, grabs the rope from the lateral movement rope to the main rope 2c, and closes the door. t2 (mode 2 to mode 3): car A is in express operation,
Stop at FS2, open the door and let the passenger get off on the way,
Grip the rope from the main rope 2b to 2a and close the door. : Car B operates in an express mode, stops at FS1, opens the door, disengages a user on the way, grabs the rope from main rope 2c to 2b, and closes the door. : The car C moves laterally, opens the door and allows the user to get in, grabs the rope from the lateral movement rope to the main rope 2c, and closes the door. t3 (mode 3, mode 4 to mode 1): car A, car B, and car C provide low, middle, and high floor services. : Car D moves laterally, opens the door and lets the user get in,
Grab the rope from the lateral movement rope to the main rope 2c and close the door.

By operating as described above, many passengers can be serviced smoothly. In addition, because cars come one after another, transportation capacity is greatly improved, and in buildings that require a large amount of transportation capacity, such as high-rise buildings, it is possible to reduce the elevator installation area without compromising transportation services and to reduce the floor space of the building. Effective use of area is possible. Although the operation method according to this embodiment shows an example of the zone service method, it may be used as a shuttle elevator that stops only on a stop floor provided in the middle of a building.

Further, unlike the circulating type elevator, many cars are not connected to one main rope, but in the above embodiment, each main rope has only two cars. Therefore, the load is the same as when driving with a car + counterweight, and the components such as hoisting machine and rope can drive the same load as before, and no new high-load components are required, resulting in low cost. You can

At the stop floor FS2, the car 1 is stopped and the clutch mechanism 13B grips the main rope 2a while the clutch mechanism 13A grips the next main rope 2b. After that, the clutch mechanism 13B releases the main rope 2a that has been coupled so far, and the car 1 moves the main rope 2b.
Combine with.

In this embodiment as well, as in the case of the twenty-ninth embodiment, a plurality of cars are lifted up and down while gripping the main rope by repeatedly attaching and detaching the main rope, so that a large amount of transportation can be obtained with a small installation area. Further, as in this embodiment, two coupling mechanisms 13 are used.

In this embodiment, one hoistway 7 is provided with, for example, three cars 1a, 1b, 1c.

A high-rise main rope 2a for pulling the high-rise cage 1a, a high-rise balance weight 6a connected to the main rope 2a to balance the high-rise cage 1a, and a high-rise hoist 3a. A reverse U-shaped rope drive system is configured with a sheave 4a for high floors which is driven by the above and the main rope 2a for high floors is wound around, and the car 1a for high floors is moved up and down in the hoistway 7. High floor basket 1
The ascending / descending of a is controlled by driving the high floor hoisting machine 3a by a control device (not shown). The same applies to the middle and lower floors. In addition, the rope drive system for the lower floors is formed so as to overlap with the rope drive system for the middle floor so as to cover the rope drive system for the middle floor in the ascending / descending direction. Furthermore, a rope drive system for high floors is stacked on top of it so as to cover it in the vertical direction without contact. For this reason, the inverted U-shaped bulge expands as the rope drive system is located above the overlap of the overlapped rope drive systems.

When this elevator apparatus is installed, the car 1 is moved up and down in the Z direction, and in a plane vacant with the car 1, the main ropes 2, and the counterweight 6, a direction orthogonal to the Z direction, for example, a direction in and out of the car 1. Is the Y direction, the direction orthogonal to Y and Z is the X direction, and the plane formed by the inverted U-shape of the rope drive system is the moving plane. Furthermore, the one with the door of the car 1 is the front,
The side with the counterweight 6 is the rear surface, the YZ plane is the side surface, the upper part of the car in the Z direction is the upper surface, and the lower part is the lower surface. Also, FIG.
FI is the boarding floor, FH, which is the standard for people and cargo to board.
Indicates a high floor, FM indicates a middle floor, and FL indicates a low floor.
In this embodiment, for example, the movement planes of the rope drive systems on the upper floors, middle floors, and lower floors are substantially the same plane. A schematic top view of this elevator device is shown in FIG. The size of the car is such that, when the lower car is configured to be larger than the upper car, and the plurality of cars 1a, 1b, 1c arranged in the hoistway are projected on the XY plane, at least the main car of the lower car is projected. The part that connects the cords projects more than the car above.

When the locus of movement of the balance weights of the rope drive system is taken as the movement line, all the movement lines of the plurality of balance weights 6a, 6b, 6c of the rope drive system form a substantially flat surface, and in particular, this embodiment In the example, a plane parallel to the Z axis is formed. Further, at least one of the plurality of rope drive systems, for example, the folding position of the main rope 2a for high floors is arranged at a position where the entire hoisting stroke (FL, FM, FH) of the hoistway 7 can be moved. The folding position of the rope drive system, for example, the main ropes 2b for the middle floor is arranged at a position where a part (FL, FM) of the entire lifting process can be moved. Further, for example, the folding position of the main rope 2c for the lower floors is arranged at a position where a part (FL) of the entire ascending / descending stroke can be moved.

Each of the rope drive systems for the lower floors, the middle floors and the higher floors has almost the same structure as the conventional one, and its operation will be described below. Each sheave 4a,
4b, 4c are rotated by respective hoisting machines 3a, 3b, 3c, and power is transmitted by traction with the main ropes 2a, 2b, 2c wound around the sheaves 4a, 4b, 4c. Baskets 1a, 1b, 1c and counterweights 6a, 6b, 6
c is each cage 1a, 1b, 1c and counterweight 6a,
The cages 1a, 1b, 1c are vertically moved along the guide rails 8 by being guided by the guide rails 8 via guide shoes (not shown) provided on the guide rails 6b, 6c. As for the raising and lowering of each car, the drive of the hoisting machines 3a, 3b, 3c is controlled by each control device (not shown) to operate.

When a plurality of rope drive systems are arranged in one hoistway 7 as in this embodiment, the hoist 3a,
This arrangement will be described because the arrangement of 3b and 3c and the roping of the main ropes 2a, 2b and 2c become complicated. In the configuration as shown in FIG. 1, the rope drive system for the uppermost upper layer does not pose a problem, but for the middle layer and the lower layer, the main rope 2 is passed through the hoistway 8 so as not to contact the upper car 1. Must be placed. Therefore, in this embodiment, when the size of the car 1 is changed and projected on the XY plane as shown in FIG. It is configured by shifting. For this reason,
The car 1 or a part of the car is protruding, and the main floor main ropes 2b and the low floor main ropes 2c are configured to pass through the rear surface of the high floor main ropes 2a.

The operation system of the elevator apparatus of this embodiment will be described below. In this example, three rope drive systems consist of a high floor (FH), a middle floor (FM),
It is configured to service each zone of the lower floors (FL). FIG. 3 is an explanatory diagram showing an example of an operation system when the zoning service according to this embodiment is performed.
In this example, it is assumed that there are the most elevator users at work, and there are no passengers going down. The operation procedure is shown below. The car 1a for higher floors operates in the order of boarding (t1) → going express operation (t2) → services on each floor (t3, t4) → return express operation (t5). Mid-floor basket 1b
Will operate in the order of car 1a departure waiting (t1) → boarding (t2) → express operation (t3) → service (t4) on each floor → return express operation (t5). Lower floor car 1c is car 1
a, 1b waiting for departure (t1, t2) → boarding (t3) →
Service on each floor (t4) → return express operation (t5).

In this embodiment, a plurality of inverted U-shaped rope drive systems are stacked in one hoistway so as to cover each other in a non-contact manner, and a plurality of cars are provided in one hoistway. Each one can drive safely and stably independently,
Since the transport amount per hoistway area can also be increased, the total plane space of the hoistway can be reduced. In particular, in order to construct a plurality of inverted U-shaped rope drive systems in a single hoistway so that they can be raised and lowered without contacting each other, as shown in FIG.
The positions of a, 5b, 5c are shifted to the rear part so that the main ropes 2a, 2b, 2c do not come into contact with each other. In addition, by changing the size of the car, the connecting portion between the main ropes for middle floor 2b and the car for middle floor 1b is shifted to the rear of the joint portion between the main ropes for high floor 2a and the car for high floor 1a, and The connecting portion between the main ropes 2c for the lower floors and the car 1c for the lower floors is shifted to the rear of the connecting portion for the middle floors. Therefore, the main rope 2 can be smoothly moved up and down, and the size of the lower car is made larger than the size of the upper car. Therefore, the capacity (capacity) of the lower car 1 can be increased.
There is also an effect that more people can be transported to lower floors, which is considered to be actually used by many people.

Further, since the moving planes of the plurality of rope drive systems are substantially one plane in the YZ plane, the moving lines of the three counterweights 6a, 6b, 6c are substantially one plane in the Y direction at the rear of the car. Can be configured to line up. Therefore, the counterweights 6a, 6b. The guide of 6c can be used also and can be made compact, and the device can be made small. Further, the entire ascending / descending stroke of the hoistway 7 is divided into a plurality of zones, which are assigned to the zones in order from above the car, and the cars are simultaneously operated in each zone. Therefore, a large number of passengers can be lifted and lowered in one hoistway 7, and the zone service, which was conventionally performed in a plurality of hoistways, can be performed in one hoistway.
For example, when going to work in the morning as shown in FIG.
About twice as many people can be transported.

Example 2. An elevator apparatus according to a second embodiment of the present invention will be described below with reference to the drawings. FIG. 4 is a perspective view schematically showing the elevator apparatus according to the second embodiment, and FIG.
5A is a top view and FIG. 5B is a side view. In one hoistway, a plurality of inverted U-shaped rope drive systems are stacked so as to cover each other in a non-contact manner, and in this embodiment, the moving planes formed by the inverted U-shapes of the three rope drive systems are substantially parallel to each other. Configured in parallel. Since the moving planes are parallel to each other, even if the inverted U-shaped bulges of the rope drive system for the lower floors and the rope drive system for the middle floors are the same, 2
The two rope drive systems do not touch. The inverted U-shaped bulge of the rope drive system for higher floors is larger than the lower two.

FIG. 6 is an enlarged perspective view showing the rear parts of the cars 1a, 1b and 1c. In the figure, 15a is a notch part provided at the rear two corners of the car 1a and 15b is for the middle floor. It is a cutout portion provided at one corner of the rear portion of the car 1b. When the plurality of cars 1a, 1b, 1c arranged in the hoistway are projected on the XY plane by this cutout portion, at least a portion of the lower car, which is connected to the main ropes, projects more than the upper car. Therefore, the cutout portions 15a, 1
The main ropes connected to the car below it can pass through 5b without contacting the car above.

Also in this embodiment, as in the case of the first embodiment, a plurality of inverted U-shaped rope drive systems are stacked in one hoistway so as to cover each other in a non-contact manner.
Since multiple cars can be independently and safely operated in one hoistway and the amount of transportation per hoistway area can be increased, the total plane space of the hoistway can be reduced. Further, since the moving planes of the plurality of rope drive systems are set to be substantially parallel to each other, the moving lines of the three counterweights 6a, 6b, 6c are arranged in the rear part of the car on a substantially flat plane in the X direction. The counterweight 6a,
6b. The guide of 6c can be used also and can be made compact, and the device can be made small. Furthermore, in a limited space, the intervals between the rope drive systems can be widened, and the risk of contact between the main ropes 2 can be reduced. Also,
By arranging a plurality of rope drive systems in this way, it is easy to arrange the hoisting machine and the sheaves 4a, 4b, 4c.

Example 3. Hereinafter, an elevator apparatus according to a third embodiment of the present invention will be described with reference to the drawings. FIG. 7A is a top view schematically showing the elevator apparatus according to the third embodiment,
FIG. 7B is a side view. In a hoistway, a plurality of inverted U-shaped rope drive systems are stacked so as to cover each other in a non-contact manner. Z
It was configured to be substantially parallel to the axis and for each of the planes of movement to intersect each other. Moreover, since it comprised in this way, even if the reverse U-shaped bulge of the rope drive system for lower floors and the rope drive system for middle floors is the same, two rope drive systems will not contact. The inverted U-shaped bulge of the rope drive system for higher floors is larger than the lower two. Further, in the second embodiment, a notch is provided at the rear of the lower car so that the main ropes connected to the lower car can pass without coming into contact with the upper car.
Is the same as.

Also in this embodiment, as in the case of the first embodiment, a plurality of inverted U-shaped rope drive systems are stacked in one hoistway so as to cover each other in a non-contact manner.
Since multiple cars can be independently and safely operated in one hoistway and the amount of transportation per hoistway area can be increased, the total plane space of the hoistway can be reduced. Further, since the moving planes of the plurality of rope drive systems are made to intersect with each other, the moving lines of the three balancing weights 6a, 6b, 6c are arranged on the rear part of the car on substantially one plane in the X direction. The balance weights 6a, 6b.
The guide of 6c can be used also and can be made compact, and the device can be made small. Further, by disposing a plurality of rope drive systems in this way, the hoisting machine and the sheaves 4a, 4b, 4c are separated from each other and are easy to dispose.

Example 4. Hereinafter, an elevator apparatus according to a fourth embodiment of the present invention will be described with reference to the drawings. FIG. 8A is a perspective view schematically showing the elevator apparatus according to the fourth embodiment,
8B is a top view and FIG. 8C is a side view. In a hoistway, a plurality of inverted U-shaped rope drive systems are stacked so as to cover each other in a non-contact manner. In this embodiment, each of the moving planes formed by the inverted U-shapes of the three rope drive systems is It is configured to be substantially parallel to the Z axis and orthogonal to at least one of the moving planes. For example, in this embodiment, the moving plane of the rope drive system for the upper floors is the YZ plane, and the moving planes of the rope drive system for the middle floor and the lower floors are the XZ planes orthogonal to the YZ plane. Along with this, the place where the high-rise floor counterweight 6a moves is defined as the rear portion, and the middle-tier floor counterweight 6b and the low-rise floor counterweight 6c are arranged so that they move to the side. in this way,
By arranging the balancing weights separately on the rear surface and the side surface of the car 1, the main rope 2 can be arranged with a large margin, the rope drive system can be easily constructed, and the depth direction of the elevator apparatus can be made thin. In this embodiment, the moving plane of the rope drive system for the high floors is the YZ plane and the counterweight 6a for the high floors is arranged on the rear surface of the car 1. However, the present invention is not limited to this.
The moving plane of another rope drive system may be the YZ plane, and its counterweight 6 may be arranged on the rear surface of the car 1.

In the second and third embodiments, a cutout is provided at the rear of the lower car 1 so that the main ropes 2 connected to the lower car 1 can pass without coming into contact with the upper car 1. However, in this embodiment, as shown in FIG.
The two cars 1 have the same shape, and the connecting parts 16b and 16c are provided so that the connecting parts of the main ropes 2 of the middle floor car 1b and the lower floor car 1c project. For this reason, the main ropes 2 coupled to the lower car 1 can pass without contacting the upper car 1.

Also in this embodiment, as in the case of the first embodiment, a plurality of inverted U-shaped rope drive systems are constructed in one hoistway such that they are not in contact with each other. Each car can operate independently and safely and stably, and the amount of transportation per hoistway area can be increased, so that the total plane space of the hoistway can be reduced. Also, by arranging multiple rope drive systems like this,
The hoisting machine and the sheaves 4a, 4b, 4c are separated from each other and are easy to arrange.

Example 5. 9 is an enlarged perspective view showing a rear surface of a car 1 of an elevator apparatus according to a fifth embodiment of the present invention. In this embodiment, the connecting portion 1 is formed so that the connecting portion between the main rope 2 of the car 1b for the middle floor and the car 1c for the lower floor projects.
6b and 16c are provided. Further, the connecting portions 16b, 16
Since both c are provided on the rear surface of the car, the main ropes 2b, 2c
Are shifted in the X direction so that they do not touch. For this reason,
The main ropes 2 connected to the lower car 1 can pass without contacting the upper car 1.

Further, in the structure shown in FIG. 1, the lower car is displaced after the upper car in order to prevent the main ropes from contacting each other, but it may be displaced to the left and right. In addition, Example 2,
As shown in 3, at least a part of the upper car may be cut out, and when a plurality of cars arranged in the hoistway are projected on the XY plane, a part that connects at least the main ropes of the lower car. If it is configured so as to project from the car above, the same effect is obtained. Furthermore, a structure may be used in which a through passage is provided in the car so that the main ropes can pass near the center of the car.

Example 6. An elevator apparatus according to Embodiment 6 of the present invention will be described below with reference to the drawings. FIG. 10 is a configuration diagram showing an elevator apparatus according to the sixth embodiment. In the figure, 20 is a counterweight that also serves as a component of the linear motor, and 21 is a counterweight guide that also serves as a component of the linear motor. The counterweight 20 and the counterweight guide 21 constitute a motor, and the counterweight 20 is connected to the main rope 2. The other components are the same as those in FIG. 1, and in particular, in this embodiment, for example, the rope drive system for the middle floor and the rope drive system for the lower floor are composed of counterweights 20b, 20c and counterweight guides 21b, 21c. A linear motor is used.

Also in this embodiment, as in the case of the first embodiment, a plurality of inverted U-shaped rope drive systems are stacked in one hoistway so as to cover each other in a non-contact manner.
Since multiple cars can be independently and safely operated in one hoistway and the amount of transportation per hoistway area can be increased, the total plane space of the hoistway can be reduced. Further, in the first embodiment, when the hoisting machines 3a, 3b, 3c are arranged in the upper part, the size of the hoisting machine is large, and therefore, the machine room portion on the hoistway 7 in which the hoisting machine is placed becomes large. I will end up. On the other hand, if the linear motor is used, the parts that used the hoisting machines 3b and 3c and the sheaves 4b and 4c in the first embodiment can be changed to the deflecting wheels 5b and 5c, so that the size of the machine room can be reduced and the hoisting and lowering can be performed. The path 7 can be made smaller. In particular, it is effective in a configuration in which a plurality of rope drive systems are stacked.

Example 7. Hereinafter, an elevator apparatus according to a seventh embodiment of the present invention will be described with reference to the drawings. 11 and 1
2 is an explanatory view showing a part of one car in an enlarged manner. Since the main rope 2 in the conventional elevator apparatus can be arranged at the center of gravity of the car 1, even if the car 1 is pulled up by the main rope 2, no moment is generated. However, in the middle-layer and low-layer main ropes 2b and 2c of Examples 1 to 6, it may be necessary to eccentrically attach them to the car 1 in order to avoid the upper car 1a. When the main rope 2 is eccentrically attached to the car 1, a moment in the −θX direction as shown by an arrow A in FIG. Therefore, in this embodiment, a car inclination suppressing mechanism is provided to correct the moment due to eccentricity. For example, in FIG.
As shown in, a balance weight 22 for correcting the weight of the car 1 with respect to the position of the main rope 2 is provided.

When the car 1 is pulled up and down by pulling the main ropes 2, a moment in the -.theta.X direction as shown by an arrow A is generated, and the car 1 tends to incline. However, since the balance weight 22 is provided on the rear surface of the car 1, a moment corresponding to the weight of the balance weight 22 is generated in the direction B that cancels the moment A. Therefore, it is possible to suppress the inclination of the car 1.

Example 8. An elevator apparatus according to Embodiment 8 of the present invention will be described below with reference to the drawings. This embodiment is a modification of the car inclination suppressing mechanism, and FIG. 13 is an explanatory view showing an enlarged part of one car. Reference numeral 23 is a reinforced guide shoe that guides the car along the guide rail 8.
The guide rails 8 are arranged so as to intersect each other.
The guide shoes 23 are usually provided between the car 1 and the guide rails 8.
Is arranged at a position opposite to the moment generated when towing, and is strengthened to support the moment. That is, when the car 1 is moved up and down by the main ropes 2, -θX
Since a directional moment A is generated, reinforced guide shoes 23 are provided at the upper left and lower right so as to support the moment A. Therefore, the guide shoe 23 can support the moment A due to the eccentricity and suppress the inclination of the car 1.
Moreover, the existing guide shoe may be provided as it is, if necessary.

Example 9. An elevator apparatus according to Embodiment 9 of the present invention will be described below with reference to the drawings. This embodiment is a modification of the car inclination suppressing mechanism, and FIG. 14 is an explanatory view showing an enlarged part of one car. 25 is a moment compensation link, for example, a parallel link. That is, parallel 4
It uses a combination of four-section links using edges. In this method, 25a to 25g form a two-stage four-joint link, and the left pin portions 26a and 26b are joined together with a cage, and the right pin portions are fitted with guide shoes 23a and 23b. And is in contact with the guide rail 8 which is a fixed part. A guide shoe 23c coupled to the car 1 is provided on the opposite side of the parallel link 25 with the guide rail 8 interposed therebetween. This guide shoe 23
Similarly to the eighth embodiment, a, 23b, and 23c are also arranged at positions facing the moment generated when the vehicle is pulled, and are strengthened to support the moment.

With this configuration, the moment force A
Therefore, even if the car 1 is inclined, the parallel link 25 maintains the parallelism. Therefore, the tilting force is converted into the pressing force to the guide rail 8 via the guide shoes 23a and 23b. Therefore, if this is the case, the car 1 is -Y
The guide shoe 2
It is supported not to move at 3c. Thus, the parallel link 25 constitutes a car inclination preventing mechanism, and the main rope 2 and the car 1
Even if the joint part of is eccentric with respect to the center of gravity of the car 1, the car 1 can be stably moved up and down without inclining.
Further, since the moment compensation link 24 can be realized with a light weight, it is suitable for practical use.

Further, the guide shoe 23 as in the eighth embodiment.
The guide rail 8
Then, the moment force A is applied to the building, and the force is further applied to the building fixing it through the guide rail 8. However, with the configuration of this embodiment, since the pressing force of the guide shoes 23a and 23b against the guide rail 8 is supported by the guide shoe 23c arranged therebetween, the twisting force acts on the guide rail 8. Without doing so, the influence on the building supporting the guide rail 8 can be reduced. In addition, traveling is stable. Moreover, in the eighth embodiment, since the inclination of the car 1 is determined by the positional accuracy of the guide shoes 23 that sandwich the guide rail 8, a high positional accuracy is required for mounting the guide shoes 23, but according to this embodiment, ,
The link mechanism is capable of contracting in the parallel direction (Y direction) and is supported by the guide shoes 25c, which does not require high mechanical precision and can reduce costs.

Example 10. Hereinafter, Example 10 of the present invention
The elevator apparatus according to FIG. This embodiment is a modification of the car inclination suppressing mechanism, and FIG. 15 is an explanatory view showing an enlarged part of one car. Reference numeral 25 is a moment compensation link, for example, an X link. That is, the two rod portions 25a and 25b form an X-link, the pin 26a is coupled to the car 1, and the pin 26b is fixed in the Y direction by the long hole 27 provided in the car 1, and the Z direction. It is fixed so that it can move freely. Guide shoes 23a and 23b are attached to the pin portion on the right side and are in contact with the guide rail 8. A guide shoe 23c coupled to the car 1 is provided on the opposite side of the guide rail 8.

With this structure, as in the ninth embodiment, even if the car 1 is inclined by the moment force A, X
The link 25 keeps the parallelism, and the tilting force is converted into a pressing force to the guide rail 8 via the guide shoes 23a and 23b. Therefore, if this is the case 1
Tries to move in parallel in the -Y direction, but supports it by the guide shoe 23c so as not to move.

With this structure, as in the ninth embodiment, X
The link 25 constitutes a car inclination preventing mechanism, and even if the connecting portion between the main rope 2 and the car 1 is eccentric with respect to the center of gravity of the car 1, the car 1 can be stably moved up and down without inclining. Further, since the guide rail 8 is not subjected to a twisting force, the influence on the building supporting the guide rail 8 can be reduced, and the machine accuracy can be reduced. Further, since the number of parts of the link mechanism is smaller than that of the ninth embodiment, the cost can be reduced.

The car 1b and the counterweight 6b are guide shoes (not shown) provided on the car 1b and the counterweight 6b, respectively.
The car 1b is vertically guided along the guide rail 8 by being guided to the guide rail 8 via the guide rail 8. At this time, the two main ropes 2b are joined on both side surfaces of the car 1b, and the two hoisting machines 3b are driven by a control device (not shown) so as to move up and down in a balanced manner in the X direction. Control. The same applies to the car 1c for lower floors. Since the car 1 is towed by the two main ropes 2 as described above, the moment due to the eccentricity can be minimized as compared with the case where the car 1 is towed by the single main rope 2.

In the above embodiment, the hoisting machine 3 is used as the main rope 2
However, the present invention is not limited to this, and it is also possible to configure one hoisting machine for the main ropes 2b for middle floors on both sides. The same applies to hoisting machines for lower floors. Further, the car 1 may be towed not only by the two main ropes 2 but also by, for example, four. Also in this embodiment, as in the first embodiment, a plurality of inverted U-shaped rope drive systems are stacked in one hoistway so that they can be lifted up and down without contacting each other. Since each car can operate independently and safely and stably, and the transportation amount per hoistway area can be increased, the total plane space of the hoistway can be reduced.

Example 12. FIG. 18 is an enlarged perspective view showing portions of the cars 1b and 1c according to the twelfth embodiment. In the eleventh embodiment, the main ropes for middle floor 2b and the main ropes for lower floor 2c are displaced in the Y direction so as not to interfere with each other during the ascending / descending movement, so that the center of gravity cannot be completely raised. On the other hand, in this embodiment, as shown in the figure, the connecting portion of the main ropes 2c for lower floors and the car 1c is made wider in the X direction than the connecting portion of the main ropes 2b for middle floors and the car 1b. is doing.
And the main ropes 2b and 2c are on both sides of the cars 1b and 1c,
In the X direction, they are connected on a line passing through the centers of gravity Gb and Gc of the cars 1b and 1c. The configurations of the other parts are the same as in the eleventh embodiment. As described above, by disposing the two pulling points so as to pass through the center of gravity of the car 1, the center of gravity can be raised more than in the eleventh embodiment.

Example 13 FIG. 19 is an enlarged perspective view showing portions of the cars 1b and 1c according to the thirteenth embodiment. In this embodiment, as shown in the drawing, the main ropes 2b for the middle floor are joined at two diagonal positions in the Y direction on both sides of the car 1b, and the joining position is the center of gravity Gb of the car 1b. It is on the line passing through. Similarly, the main ropes for lower floors 2c are joined on both sides of the car 1c at diagonal positions in the Y direction, and the joining position is on a line passing through the center of gravity Gb of the car 1c. Furthermore, the connecting parts for the middle floor and the connecting parts for the lower floor are offset from each other. The configurations of the other parts are the same as in the eleventh embodiment. According to this structure, as in the twelfth embodiment, the two hoisting points are arranged so as to pass through the center of gravity of the car 1, the center of gravity can be hoisted, and an elevator apparatus that can stably raise and lower the car can be obtained.

Example 14 FIG. 20 shows the first embodiment of the present invention.
It is a side view which shows the elevator apparatus concerning 4th typically.
In the figure, the rope drive system for high floors has the same structure as that in the first embodiment. The rope drive system for the middle floor constitutes a 2: 1 roping in which the main ropes 2b are turned under the car 1b and the car 1b is supported from below by the deflecting wheels 5b from both sides. A rope drive system is not configured for the lower-floor car 1c, and a hydraulic elevator 28 that hydraulically lifts the car 1c from below is used.

The rope drive system for the middle floor in this embodiment shows another embodiment in which the main ropes 2 are supported on both sides of the car 1. In this way, if the main rope 2b is turned below the car 1b and supported from below on both sides of the car 1b, it can be driven without generating a moment.
Furthermore, since the lower-level floor car 1c is configured by using a hydraulic elevator that is hydraulically lifted, the higher-level car 1c
There is no interference between the car 1b for the middle floor and the rope drive system for the lower floors, and the structure is simple. Further, the center of gravity of the cars 1a and 1b on the upper floors and the middle floors can be raised more easily than in the eleventh embodiment.

This is the floor for boarding the lower floor car 1c.

As shown in the figure, a plurality of boarding floors are provided on the first floor or the standard boarding floor, and they are connected to each other by, for example, stairs. Passengers can board the car from the car loading floor that corresponds to the desired floor. In this case 3
You can start boarding one car at the same time, and when you finish boarding the three cars, you can start operating three cars at the same time. Therefore, as in the case of the operation in the first embodiment shown in FIG. 3, at t2, waiting for the passenger to board the middle floor car 1b, or t
In 3, it is not necessary to wait for getting on the lower floor car 1c, and the multi-transport efficiency can be further improved. In this embodiment, a plurality of floors are connected to each other by stairs on the first floor and the standard boarding floor.

Example 16 Hereinafter, Example 16 of the present invention
The elevator apparatus according to FIG. The present invention includes a plurality of cars in one hoistway, and the cars can be independently moved. When operating a car with such a configuration, it is necessary to take safety measures that were not necessary in the past. This embodiment is for safe operation. FIG. 22 is a flowchart showing an example of control at the start of moving the car according to the sixteenth embodiment. This control can be executed by, for example, a control device that controls the hoisting machine 3.

First, in step ST1, it is determined whether or not there is another car 1 in the moving direction of the car to be controlled. If there is no other car 1, the movement of the car to be controlled is started in step ST4. If there is another car in the moving direction in the determination in step ST1, it is determined in step ST2 whether the distance between the car and the car to be controlled is within a certain distance. The distance between the cars can be known from the operating states of the hoisting machine controlled by the controller and the hoisting machines of other cars. In addition, the constant distance is a safe distance even if the car to be controlled starts moving, and various cases can be considered depending on the moving speed. It is set to about the braking distance.

If the distance between the cars is larger than a certain distance in step ST2, it is considered safe to start the movement, and the movement of the car to be controlled is started in step ST4. When the distance between the cars is within a certain distance in step ST2, the time is waited in step ST3, and the determination is repeated in step ST2. In this way, it is determined whether or not the car may be moved before the car starts moving, and control is performed so that the car does not start moving when the distance between other cars in the car moving direction is less than a certain distance. Therefore, even if a plurality of cars are provided in one hoistway, the elevator can be operated safely and an elevator device with high transportation efficiency can be obtained.

Example 17 Hereinafter, Example 17 of the present invention
The elevator apparatus according to FIG. Similar to the sixteenth embodiment, this embodiment is for avoiding collision between cars and for operating safely. FIG. 23 is a car 1a for the upper floors and a car 1b for the middle floors of the elevator apparatus according to the seventeenth embodiment.
It is a perspective view which expands and shows. In the figure, reference numeral 30 is a distance measuring device that measures the distance between the cars without contact with, for example, a laser.

The distance measuring device 30 is provided on the car 1b for the middle floor, emits the laser beam upward, receives the laser beam reflected by the car 1a for the upper floor above, and detects the time difference between them. It measures distance. In the sixteenth embodiment, the distance between the cars is obtained by calculating the information from the hoisting machine by the control device, and the safe operation is controlled based on this value.
In this embodiment, the distance between the cars is further measured by the distance measuring device 30.
To measure. Using both of these values, the safety at the start of moving the car is monitored based on the flowchart of FIG. Since the distance measuring device 30 is provided to actually measure the distance between the cars, reliability is enhanced rather than relying only on the value calculated by the control device. In the above embodiment, the distance measuring device 30 uses a laser, but the distance measuring device 30 is not limited to this. For example, a device that measures a distance using ultrasonic waves or magnetism may be used. Further, instead of the non-contact distance measuring device, a direct distance measuring means for connecting the cars with a wire may be used. Further, the guide rail 8 or the hoistway 7 may be provided with a linear scale.

Example 18. Hereinafter, Example 18 of the present invention
The control method of the elevator apparatus according to FIG. In this embodiment, in order to safely operate an elevator apparatus provided with a plurality of cars in one hoistway, the moving speed of the corresponding car 1 is controlled according to the distance between adjacent cars 1 or the relative speed. is there. As shown in the sixteenth embodiment, the distance between the cars 1 and the relative speed can be calculated and obtained by the control device from the information of the hoisting machine or can be obtained and measured by the distance measuring device 30 provided in the car.

FIG. 24 is a flow chart showing an example of control at this time. In normal operation, a speed pattern of acceleration / constant speed / deceleration is set in advance as the rated traveling speed of the car 1. Arbor 1 starts moving, step ST11
Start rated driving with. Hoisting machine 4 in step ST12
Calculate the car distance between adjacent cars from the hoisted state.
Further, in step ST13, the relative speed between the adjacent cars is calculated from the hoisting state of the hoisting machine 4. Based on this relative speed between cars, a safe distance between cars is calculated even at that relative speed (step ST14).

Next, in step ST15, the actual inter-car distance obtained in step ST12 and step ST14
The safety distances from the relative speeds obtained in step 1 are compared, and if the actual distance between the cars is large, the rated travel is commanded in step ST16. The safety distance from the relative speed obtained in step ST14 is compared, and if the actual inter-car distance is small or equal, it is determined to be dangerous, and the car is decelerated so that the relative speed becomes small in step ST17.

In the above embodiment, the distance between the cars and the relative speed between the cars are calculated from the hoisting condition of the hoist, but the present invention is not limited to this.
The same effect can be obtained by using a sensor such as a speedometer. In this embodiment, the moving speed of the car is controlled according to both the distance between the adjacent cars and the relative speed thereof, but the movement of the car according to either of the distance between the adjacent cars and the relative speed thereof. It may be configured to control the speed. As described above, since the moving speed of the corresponding car 1 is controlled according to the distance between the adjacent cars 1 and the relative speed,
Even if a plurality of cars are provided in one hoistway, the elevator device can be operated safely. In particular, although the vehicle runs at the rated speed in the normal operation, even if the distance between the adjacent cars is shortened or the speed of the car becomes abnormal due to some cause during the operation, according to this embodiment, By controlling the moving speed, it is possible to operate safely and efficiently.

Example 19 Hereinafter, Example 19 of the present invention
A control method for the elevator apparatus according to the above will be described. As shown in the sixteenth embodiment, the distance between the cages can be calculated and obtained by the control device from the information of the hoisting machine, or can be obtained by measuring with the distance measuring device 30. Using this inter-car distance, the safety at the start of car movement is monitored based on the flowchart of FIG. In this embodiment, not only at the time of starting the movement of the car, but for example, when the distance between the cars approaches a distance that is dangerous considering the braking force of the car during operation, for example, the mode is switched to the emergency operation mode for control. .

FIG. 25 is a flow chart showing an example of the control at this time. In step ST31, for example, the distance of the upper car is detected by the control device or the distance measuring device 30. In step ST32, it is determined whether the car distance is within a certain distance. The constant distance at this time is a distance in which the distance between the cars is dangerous considering the braking force of the cars, and for example, the height of the cars is set. If it is determined that the distance is equal to or more than the predetermined distance, it is within the safe range, and the operation is continued in step ST33.

If the distance is within a certain distance in the judgment of step ST32, it is regarded as a dangerous range, and the operation mode is switched to the emergency operation mode. That is, in step ST34, both cars are urgently decelerated,
If there is a shelter nearby, shelter it (step ST3).
5, 36). If there is no shelter nearby, step ST
At 37, since the danger cannot be avoided and it is an emergency, the operation of all the cars is stopped. It is also possible to resume normal operation when the danger is avoided in the case of evacuation.

According to this embodiment, in a vehicle having a plurality of cars in one hoistway, even if the distance between the cars approaches a dangerous distance for some reason, the danger can be avoided and the safety can be improved. There is an effect that an elevator device with high property can be obtained.

In the figure, reference numeral 32 denotes a car proximity detector having a sensor at the tip, for example, a rod of several meters, and mechanically detects that another car is approaching. The car proximity detector may be a system in which one car is provided with a sensor, the other car is provided with a fin extending a few meters above or below, and the fin enters the sensor to perform detection. Alternatively, a method of operating a limit switch as in the conventional pit section may be used. The distance between the cars can be known from the operating states of the hoisting machine controlled by the control device and the hoisting machines of other cars, but for further safety, distance measurement is performed in this embodiment. A container 30 and a car proximity detector 32 are provided.

Since the distance measuring device 30 has been described in the seventeenth embodiment, the car proximity detector 32 will be described here. The safety is monitored by controlling the distance between the cars. In this embodiment, the control by the control device becomes abnormal and the control cannot be performed. Distance measuring device 3

In the figure, 33 is a disc brake that operates on the hoisting machine 4, and 34 is an emergency stop provided between the car 1 and the guide rail 8.

In this embodiment, two emergency stop mechanisms, a disc brake 33 and an emergency stop 34, are provided. When mechanically detecting that the other car 1 is approaching, the disc brake 33 interlocks with this and forcibly stops the rotation of the hoisting machine 4, and stops the car 1. Further, the emergency stop 34 fixed to the car 1 is connected to the guide rail 8 by grasping the guide rail 8 and stops the movement of the car 1.

According to this embodiment, in a car having a plurality of cars in one hoistway, even if the distance between the cars approaches a dangerous distance for some reason, the cars are stopped to avoid the danger. It is possible to obtain an elevator device with high safety. In this embodiment, two emergency stop mechanisms of the disc brake 33 and the emergency stop 34 are provided, but either one may be provided.

In the first to the twentieth embodiments, the operation system has been described in which the entire ascending / descending process of the hoistway is divided into a plurality of zones and the cars are assigned and serviced. However, the present invention is not limited to this. It may be an operation method such as a lobby method, or may be an operation method that operates according to a call without specifying a service method. In addition, although examples 16 to 20 have been described for improving safety reliability, these safety devices may be any of the above, may be provided in combination, or may be omitted.

Example 21. Hereinafter, Example 21 of the present invention
The elevator apparatus according to FIG. 28,
FIG. 29 is a side view schematically showing an elevator apparatus according to Example 21. In the first embodiment, the rope drive system for the upper floors has the folding position of the main rope 2a arranged at a position where the hoistway can be moved in the entire hoisting stroke, and the other rope drive systems can move a part of the whole hoisting stroke. Main rope 2 in position
Although the folding positions of b and 2c are arranged, in this embodiment, the folding positions of the main ropes 2a, 2b and 2c are arranged at positions where all rope drive systems can move in the entire ascending and descending strokes of the hoistway. There is.

In the zone service operation system as in the first embodiment, the moving range of the car 1 is fixed, and the car 1 must be selected according to the desired floor. On the other hand, according to the configuration of this embodiment, when a passenger gets on the car, he / she can independently move in a range where all of the plurality of cars 1 do not come into contact with the upper and lower cars 1 in response to the passenger's request. You can In the first embodiment, the hoisting machine 3, the sheave 4, the deflector 5
There must be a machine room to store the
With this configuration, all can be stored in one machine room.

In FIG. 28, when the inverted U-shaped rope drive system is projected onto the YZ plane, the inverted U-shaped rope drive system is constructed so as to overlap with each other in the ascending / descending direction in a non-contact manner. When the plane composed of the drive system is a moving plane, an example is shown in which the moving planes of the plurality of rope drive systems are configured to be substantially the same plane. Further, FIG. 29 shows an example of a configuration in which each of the moving planes of the plurality of rope drive systems is substantially parallel to the Z axis and each of the moving planes is substantially orthogonal to at least one of the other moving planes. . In this way, in both configurations, the folding positions of the main ropes 2a, 2b, 2c are arranged so that all rope drive systems can move in the entire ascending / descending stroke of the hoistway.

Example 22. Hereinafter, Example 22 of the present invention
The elevator apparatus according to FIG. FIG. 30 is a side view schematically showing an elevator apparatus according to Example 22. In this embodiment, the entire hoisting stroke of one hoistway 7 is performed in a plurality of zones, for example, a high floor (FH) and a middle floor (FH).
M) and lower floors (FL) are divided into three zones, and the moving ranges of the plurality of cars housed in the hoistway are assigned from the top of the zone in order from the one located at the top. That is, the high floor car 1a moves in the high floor zone (FH), the middle floor car 1b moves in the middle floor zone (FM), and the low floor car 1c moves in the low floor zone (FL).

As described above, in the zone service operation system in which only a part of the entire ascending / descending stroke is stopped when requested, and the other floors are not stopped, the plurality of cars 1 accommodated in one hoistway are not stopped. The upper floor of the zone divided from the car 1 located above is served. Also,
As shown in the figure, two hoistways 7 are provided to connect the high-rise floor cars 1a, the mid-rise floor cars 1b, and the low-rise floor cars 1c, and use one of the cars as a counterweight for the other car. is doing. In addition, the hoisting machine 3, the sheave 4, the deflector 5
Is shared for each zone. Of course, as in the conventional case, a system having one hoistway and a counterweight may be provided.

When the service areas of the cars 1 are completely divided in this way, there is an effect that an elevator device that is safe and has a simple structure can be obtained without the risk of cars coming close to each other abnormally.

Example 23. Hereinafter, Example 23 of the present invention
The elevator apparatus according to FIG. FIG. 31 is an explanatory diagram for explaining a floor call button in operation of the elevator apparatus according to the twenty-third embodiment. In this operation system, as shown in FIG. 28, the configuration of each car 1 is configured so as to be able to go up and down in the entire stroke of the hoistway, and all the hoisting machines 3, sheaves 4 and deflecting wheels 5 are provided in one machine room. Stored in M. The operation system uses the zone service system, and the upper floor car 1a covers the upper floors (FH) of 21F to 30F, and the middle floor car 1b covers the upper floors (FH) of 11F to 20F. In the low-rise floor car 1c, the low-rise floor (FL) range of 1F to 10F is targeted. The standard boarding floor (FI) is 1F. In addition, in the figure, (a) shows a configuration example of floor call buttons of 21F to 30F, (b) shows a configuration example of floor call buttons of 11F to 20F, and (c) shows a configuration example of floor call buttons of 2F to 10F. The number corresponding to the floor is written in □.
For example, on the floor call button of 25F, 26F is written in □ of Δ for instructing to go up, and 24F is written in □ of ▽ for instructing to go down.

In many cases, the call buttons on each floor of the conventional elevator apparatus have only buttons indicating up and down. However, as in the present invention, when a plurality of cars are operated in one hoistway and, for example, the zone service system is used, it is difficult to allocate cars without knowing which zone above or below the car is desired. Therefore, it is efficient to arrange call buttons for each zone on the call buttons on each floor as shown in a, b, and c in FIG. 31 so that passengers can press the button for their own target zone. You can operate the basket.

Further, if a call button for the first floor (FI), which is considered to be used particularly frequently, is provided on this call button, the operation can be more efficiently performed. This button may be able to press all floors. Further, the service zones of each car 1 may be configured to overlap at least one floor so that the passengers can transfer to each zone. For example, 21F
May allow both mid-level and high-level cars to be stopped. In addition, as a service when people on the upper floors want to go to the lower floors and vice versa, it is possible to stop at least part of the lower floors while the high car is descending, You may be able to rise.

In the above elevator apparatus, a space for storing the car 1 may be provided below the first floor or the standard boarding floor. If this space is provided below the hoistway 7,
Easy to configure. Also, if a plurality of hoistways 7 are provided, they can be used as an emergency shelter during operation. Further, the plurality of cars 1 provided in one hoistway 7 is not limited to three, and may be two or three or more. Further, although the hoisting machine 3 and the counterweight 6 are provided on each car 1, any one of them may be combined. Further, although the structure in which the hoisting machine 3, the sheave 4, and the main measure 2 constitute the driving means has been mainly described, a system using a linear motor as shown in FIG. The method may be used. Further, the main measure 2 may be a chain instead of the wire rope, or other transmission means. Also, basket 1
Can be sheltered from the hoistway 7, and the lower car 1 can be the upper car 1
By providing a mechanism that can overtake passengers, the operating efficiency can be further improved. Furthermore, in Examples 1 to 23, only one car 1 is provided at a place where one operation is performed, but two cars may be connected in series like a double deck. That is, in FIG. 1, it can be constituted by three places × 2 = 6 cars, which further increases the transportation amount. Of course, two or more may be used, or only a part may be a double deck.

The elevator apparatus constructed as in Examples 1 to 23 can be constructed with almost no change in the components of the conventional elevator apparatus, and a large number of personnel can be transported in a narrow elevator installation area. Also, since different floors can be serviced by multiple cars, it is possible to provide almost the same service as before even when transporting a large quantity. Therefore, in a building requiring a large amount of transportation capacity such as a high-rise building, the elevator installation area can be reduced without lowering the transportation service, and the floor area of the building can be effectively used.

Example 24. Hereinafter, Example 24 of the present invention
The elevator apparatus according to FIG. 32,
33 is a side view schematically showing an elevator apparatus according to Example 24. FIG. The elevator apparatus according to Examples 1 to 23 is called 1: 1 roping, and is a roping method in which the balance weight moves 1 time when the car moves 1 time. In this embodiment, as another roping method, an embodiment relating to an elevator apparatus using 2: 1 roping in which one side of a main rope is connected to a fixed end as shown in FIG. 47 will be described. In this system, the car moves 1/2 of the movement of the main rope 1.

FIG. 32 shows a state in which a car is loaded,
FIG. 33 shows a state in which the car stops at the upper floor. In the figure, FI is the boarding floor, and FS1 and FS2 are F
Floors higher than I, for example, lower floors and middle floors. One end 2a of the main rope 2 is connected to the fixed portion, and the other end 2b is connected to the counterweight 6 via the sheave 4. First basket 1a
Are directly connected to the main rope 2. Further, the second car 1b is indirectly hung down to the main rope 2 via the deflecting wheel 5.

As shown in the figure, from the state where the first car 1a is fixed to the boarding floor FI, the sheave 4 is driven by the hoisting machine 3.
When is rotated, power is transmitted to the main rope 2 by traction, and the cars 1a and 1b rise. For example, as shown by arrow A in FIG. 33, when the second car 1b is moved from the boarding floor FI to the lower floor FS1, the first car 1a is moved to the arrow B.
Move from the boarding floor FI to the middle floor FS2 as shown in FIG. That is, while the second car 1b moves by 1, the first car 1a moves by 2. In this way, if one end of the main rope 2 is fixed and the second car 1b is connected to the main rope 2 via the wheel 5, the first car 1a and the first cage 1a directly connected to the main rope 2 are connected. Hoisting machine 3 with 2 baskets 1b
The ascending / descending distance is different.

As described above, in this embodiment, two cars 1a and 1b can be simultaneously driven by one hoistway, and the two cars 1a and 1b are driven by one drive motor. Can serve different floors. For this reason,
A single hoistway can carry a large number of passengers and lower floors FS1,
The middle floor FS2 can be used as a sky lobby floor of a high-rise building or the like, and can be used as a shuttle elevator that makes a direct round trip to the sky lobby floor. Further, the conventional elevator apparatus can be constructed with almost no change in its components, and a large number of personnel can be transported in a small elevator installation area. Also, since one hoist can service multiple floors with different baskets, it can be serviced more efficiently than conventional double-deck elevators. In addition, if you use multiple hoisting machines, the degree of freedom of each car will increase and service will be further improved. Therefore, in a building that requires a large amount of transportation capacity such as a high-rise building, the elevator installation area can be reduced without lowering the transportation service, and the floor area of the building can be effectively used.

Example 25. Hereinafter, Example 25 of the present invention
The elevator apparatus according to FIG. FIG. 34 is a side view schematically showing an elevator apparatus according to Example 25. In this embodiment, a system using 2: 1 roping is used and three cars are provided. The second car 1b and the fixed portion are connected to each other by the second main rope 2c, and the third car 1c is indirectly suspended from the second main rope 2c via the deflecting wheel 5. Other configurations are similar to those in FIG.

Similar to the twenty-fourth embodiment, when the sheave 4 is rotated by the hoisting machine 3 from the state where the first car 1a is fixed to the boarding floor FI, power is transmitted to the main ropes 2 by traction, and the car 1a, 1b, 1c rise. For example, when the second car 1b is moved from the boarding floor FI to the lower floor FS1, the first car 1a moves from the boarding floor FI to the higher floor FS.
Moving to 3, the third car 1c moves from the boarding floor FI to the lower floor FS0. This lower floor FS0 is a boarding floor FI
To the lower floor FS1 are the central floors. That is, when the first car 1a moves 1 time, the second car 1b moves 1/2, and the third car 1c moves 1/4. In this way, one end of the main rope 2 is fixed, the second cage 1b is joined to the main rope 2 via the deflecting wheel 5, and the second cage 1b is further connected.
If the third car 1c is connected through the baffle wheel 5, the first car 1a and the second car 1 directly connected to the main ropes 2 will be described.
The hoisting distance by the hoisting machine 3 is different between b and the third car 1c.

According to this embodiment, the same effect as that of the twenty-fourth embodiment is obtained, and further three cars are provided as compared with the two cars, so that the transportation amount can be further improved. It is also possible to combine more cars in the same way.

Example 26. Hereinafter, Example 26 of the present invention
The elevator apparatus according to FIG. 35: is a side view which shows the elevator apparatus by Example 26 typically. In the figure, 3b is a hoisting machine, which is arranged at a portion which is the fixed end 2a of FIG. Boarding floor FI
When the sheave 4a is rotated by the hoisting machine 3a from the state where the first car 1a is fixed, the power is transmitted to the main rope 2 by the traction, and the cars 1a and 1b rise. For example, when the second car 1b is moved from the boarding floor FI to the lower floor FS1, the first car 1a moves from the boarding floor FI to the middle floor FS2. When the sheave 4b is further rotated, the second car 1b can be moved to any position between the lower floor FS1 and the middle floor FS2.

In this way, the hoisting machine 3a,
If 3b is provided and the second car 1b is coupled to the main rope 2 via the deflecting wheel 5, the hoisting is performed by the first cage 1a and the second cage 1b directly coupled to the main rope 2. The ascending / descending distances of the machines 3a and 3b are different. In the case shown in FIG. 32, the moving distance of the car 1a is determined by the hoisting machine 4 and the car 1b can move only half the stroke, but in this embodiment, the car 1a
b can also be moved separately. In this way, although the number of drive motors is increased, the degree of freedom of the car 1b is increased.

Example 27. Hereinafter, Example 27 of the present invention
The elevator apparatus according to FIG. 36: is a side view which shows the elevator apparatus by Example 27 typically. In the figure, 3b and 4b are hoisting machines and sheaves, and the second car 1b is the first car 1a via the sheave 4b.
Is bound to. That is, the first car 1a is directly connected to the main ropes 2, and the second car 1b is indirectly connected to the main ropes 2 via the sheave 4b.

The operation of the cars 1a and 1b thus constructed will be described. The second car 1b moves by the same distance as the first car 1a moves up and down by the hoisting machine 3a. Further, the second car 1b can be independently moved up and down by the hoist 3b. In this way, the first car 1a and the second car 1b, which are directly connected to the main ropes 2, can obtain different lifting distances. Therefore, the same effect as that of Example 26 is obtained.

Note that in Examples 24 to 27, only one car is provided in a place where one operation is performed, but two cars are connected like a double deck, that is, in FIG. 32, 2 cars × 2 = 4. It may be a system composed of individual baskets. Further, two or more cars may be provided at the place where one operation is performed.

Example 29. Hereinafter, Example 29 of the present invention
The elevator apparatus according to FIG. 38 is a side view schematically showing an elevator apparatus according to Example 29. As shown in FIG. In the configuration of the elevator apparatus described in the above Examples 1 to 28, the car moves up and down in the hoistway, and the main rope was reciprocating, but in this embodiment, the ring-shaped main rope is rotated. It is configured to let the basket circulate. In the figure, 1a to 1h are circulating cars, for example, 8 cages, 2a is a main rope that goes around the high-rise section, 2b is a main rope that goes around the middle-rise section, 2c is a main rope that goes around the low-rise section, and 3a is a high-rise section main A hoisting machine for ropes, 3b is a hoisting machine for middle-layer main ropes, 3c is a hoisting machine for low-rise main ropes, 4a is a sheave for high-rise main ropes, 4
b is a sheave for the middle-layer main rope, 4c is a sheave for the low-rise main rope,
5a is a deflector wheel for high-rise main ropes, 5b is a deflector wheel for mid-rise main ropes, 5c is a deflector wheel for low-rise main ropes, 7A is an ascending path for raising the car 1, and 7B is for descending the car 1. Downhill, 10
a, 10b, 10c are provided on the lower deflecting wheels of the main ropes 2a, 2b, 2c, and 11a to 11h are provided on the cages 1a to 1h, respectively. It is a gripping mechanism. Further, 12a is an upper car lateral movement mechanism, 12b is a lower car lateral movement mechanism, and
Are loops A and LB formed by the rope drive system on the upper floors
Is loop B, LC formed by the rope drive system on the middle floor
Is a loop C formed by the rope drive system on the lower floor. The arrow U indicates the ascending direction of the car, and the arrow D indicates the descending direction of the car.

The structure of the elevator apparatus according to this embodiment will be described below with reference to the drawings. In loop A (LA), the cages 1g and 1e are the main rope 2a and the rope gripping change mechanism 11g,
They are connected and balanced through 11e. Also, loop B
In (LB), the cars 1h and 1d are connected and balanced with the main rope 2b via the rope grip change mechanisms 11h and 11d. Further, in the loop C (LC), the cars 1a and 1c are connected to the main rope 2c via the rope grip change mechanisms 11a and 11c and are in balance with each other. Further, the cars 1b and 1f are connected to the moving ropes of the lateral movement mechanisms 12a and 12b via the rope grip change mechanisms 11b and 11f, respectively.

Next, the operation of this embodiment will be described. In the loop C (LC), the car 1a is lifted in the U direction by the sheave 4c by the driving force of the hoist 3c, and at the same time,
The car 1c balanced with the car 1a descends in the D direction. Almost in synchronization with this movement, the car 1h and the car 1d move in the loop B (LB), and the car 1g and the car 1e move in the loop A (LA). During this vertical movement, the car 1b is laterally moved from the descending direction to the ascending direction by the lateral moving mechanism 12b. Along with this, the car 1f is moved laterally 12
By a, it moves laterally from the ascending direction to the descending direction. That is,
Each of the cars 1b and 1f laterally moves in the direction opposite to the direction in which the cars have been moved so far.

When the car 1a reaches the stop floor (FS1), the car 1a stops and the passengers get on and off. During this time, the rope gripping change mechanism 11a of the car 1a operates and grips the rope from the low-layer main rope 2c to the middle-layer main rope 2b. Similarly, basket 1
h, 1e, and 1d stop at the stop floor, and at the same time, the rope is grabbed and changed to the next main rope 2. At this time, basket 1c, basket 1g
Arrive at the getting-off floor (FI) and the top floor (FS3) respectively, and at the same time when the passengers get off, the rope gripping mechanism 11
c and 11g operate to grab the main rope 2c and the main rope 2a and move them to the moving ropes of the car lateral movement mechanisms 12b and 12a. Next, the cars 1b and 1f that have completed the lateral movement grip the main ropes 2c and 2a from the rope for lateral movement and change the grip.

In this way, a plurality of ring-shaped main ropes that circulate a part of the ascending / descending stroke are provided, a part of these are crossed, and one pair of cars is connected to one main rope in a balanced manner. The car moves up and down while grasping the main rope by repeatedly attaching and detaching it. Therefore, many cars can be operated under a load similar to the conventional load, a large amount of transportation can be obtained with a small installation area, low cost can be configured, and safe operation can be achieved. In particular,
Compared with the conventional ring-shaped elevator device shown in FIG.
Since the number of cars 1 connected to one main rope 2 can be reduced,
It is possible to prevent a large load from being applied to the main rope and the hoisting machine.

Further, in this embodiment, in one rope drive system, the cages of substantially balanced weights are attached to and detached from the main ropes thereof substantially in synchronization, so that a counterweight is not necessary and the structure becomes complicated. And a safe elevator device can be obtained. In addition, since all the cars 1 are attached to and detached from the main ropes 2 almost at the same time, it is possible to prevent the balance from being lost, keep the distance between the cars 1 constant, and obtain a safe elevator device. Also, in this example,
Eight cages 1 are provided, and the number of cages is not limited to this, but if at least twice the number of main ropes 2 is provided, one pair of cages 1 can be provided by one ring-shaped rope drive system. Can be combined. For example, when the number of passengers during the daytime is small, the number of cars may be the minimum number (the number of main ropes × 2), and when the number of passengers is high in the morning and evening, more cars may be combined. Further, in this embodiment, three ring-shaped rope drive systems are provided, but the number is not limited to this, and any number may be configured.

The operation system of the elevator apparatus of this embodiment will be described below. In this embodiment, three ring-shaped rope drive systems consist of a high floor (FH) and a middle floor (FH).
M) and lower floors (FL) are divided into each zone to be serviced. FIG. 39 is an explanatory diagram showing an example of an operation system when the zoning service according to this embodiment is performed.

The operation procedure is shown below. t1 (mode 1 to mode 2): car A is in the express operation,
Stop at FS1, open the door and let the passenger get off on the way,
Grab the rope from the main ropes 2c to 2b and close the door. : The car B moves laterally, opens the door to allow the user to get in, grabs the rope from the lateral movement rope to the main rope 2c, and closes the door. t2 (mode 2 to mode 3): car A is in express operation,
Stop at FS2, open the door and let the passenger get off on the way,
Grip the rope from the main rope 2b to 2a and close the door. : Car B operates in an express mode, stops at FS1, opens the door, disengages a user on the way, grabs the rope from main rope 2c to 2b, and closes the door. : The car C moves laterally, opens the door and allows the user to get in, grabs the rope from the lateral movement rope to the main rope 2c, and closes the door. t3 (mode 3, mode 4 to mode 1): car A, car B, and car C provide low, middle, and high floor services. : Car D moves laterally, opens the door and lets the user get in,
Grab the rope from the lateral movement rope to the main rope 2c and close the door.

By operating as described above, many passengers can be serviced smoothly. In addition, because cars come one after another, transportation capacity is greatly improved, and in buildings that require a large amount of transportation capacity, such as high-rise buildings, it is possible to reduce the elevator installation area without compromising transportation services and to reduce the floor space of the building.
