Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an elevator and an elevator-type multi-story parking facility. More specifically, the present invention relates to an elevator-type multi-story parking facility in which parking spaces for storing vehicles are arranged in a plurality of upper and lower stages along a hoistway of an elevator for transporting a vehicle, and an elevator applicable to the parking facility.

[0002]

2. Description of the Related Art FIG.
3 shows a conventional elevator-type multi-story parking facility 61. In this parking facility 61, a pallet 63 for mounting on a vehicle is disposed inside a building 62 so as to be able to be placed in a plurality of upper and lower stages. The elevator 64 moves the pallet 63 up and down between the entrance / exit floor 65 of the parking facility 61 and the designated stage to transport the vehicle M. Conventionally, in such parking facilities, a so-called traction system and a so-called winding system are known as elevator lifting mechanisms.

The traction system is shown in FIGS.
As shown in FIG. 13, an elevator frame 66 as a transport member and a counterweight 67 in the multi-story parking facility 61 (FIG. 13) are connected in a weight-balanced manner by a rope 68 such as a wire rope, and an intermediate portion of the rope 68 is connected. It is wound around a hoisting sheave (called a driving sheave) 70 of a single driving device 69 as a whole. The rope 68 is connected to the four corners of the substantially rectangular elevator frame 66.
Then, the drive sheave 70 is rotated, and the cable 68 is pulled by the frictional force of the drive sheave 70 to thereby lift the elevator frame 6.
6 is raised and lowered. The weight of the counterweight 67 makes the lifting force and the descent force of the driving device 69 uniform. An example of such an elevator is disclosed in
And Japanese Patent Application Laid-Open No. 8-86112.

[0004] On the other hand, in the winding drum type, although not shown, the four ropes connected to the four corners of the elevator frame are wound up by one winding drum (also referred to as a drum), and the elevator is raised and lowered. The cable is wound around the winding drum a plurality of times with its end fixed to the winding drum. It's like a winch drum. In many cases, a counterweight is used in order to equalize the lifting force by the driving device. An example of a winding drum type elevator is disclosed in Japanese Patent Application Laid-Open No. 7-7113.

[0005] Regardless of the traction type or the winding drum type,
Since a plurality of cables are operated by a single driving device, it is necessary to use a driving device having a large output.
As a result, the entire driving device including the motor and the speed reducer becomes large. In addition, pulleys or the like that deflect or turn the cable must be concentrated toward one driving device.
As a result, in a conventional parking facility, one floor is required as the machine room 71 to accommodate such a driving device (see FIG. 13). Therefore, the number of vehicles accommodated is limited accordingly. In addition, construction costs increase due to an increase in the overall height of parking facilities. Furthermore, the cost of auxiliary equipment such as fire extinguishing equipment and ventilation equipment increases according to the volume of the building.

[0006] In the traction type elevator disclosed in Japanese Patent Application Laid-Open No. 2-210166, the driving system is divided into two systems by using two driving devices. But,
In order to keep the elevator frame (elevator) horizontal, it is necessary to keep the level of each cable connected to the four corners the same. In addition, both driving systems need to be operated synchronously. In this case, a level detector required for control by software and complicated control software for performing synchronization during high-speed ascent / descent are required. Both maintenance and operation adjustment become complicated.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and can easily ascend and descend while maintaining a horizontal state of a transport member (elevator frame) without performing special complicated control. It aims to provide elevators. It is another object of the present invention to provide an elevator-type multi-story parking facility to which the elevator is applied.

[0008]

The elevator according to the present invention comprises:
A transport member for mounting an elevating object, and a plurality of electric motor-type driving devices for elevating the transport member,
A plurality of cords driven by each drive unit, each cord being connected to each of two connection points of the transport member, and connecting the connection points of the cords of one drive unit. The virtual straight line and the virtual straight line connecting the connection points of the cables of the other drive devices intersect within the outer frame range of the transport member in plan view.

Since the elevator drive device is separated, the degree of freedom of arrangement in the parking facility is increased by miniaturization, so that the space in the parking facility can be effectively used. Furthermore, since the virtual straight lines connecting the connecting points of the plurality of cords in the transport member intersect at the position of the center of gravity, the drive system including one drive device and the drive system including the other drive device require a mechanical Synchronize. This is because the rotation speed of the electric motor generally decreases as the load applied thereto increases, and the rotation speed increases as the load applied decreases. That is, when the lifting speed of the transport member by one drive system is going to be faster than the lifting speed of the other drive system, the weight of the one drive system increases, and the rotation speed of this motor decreases. Conversely, the rotation speeds of the motors of the other drive systems increase. As a result, a difference in the elevating speed is avoided, and the transport member can maintain a horizontal state.

According to another elevator of the present invention, there is provided a substantially rectangular transport member for mounting an object to be raised and lowered, first and second electric motor type driving devices for lifting and lowering the transport member, and A first cable connected to each of two diagonal corners of the transport member driven by the driving device, and a second cable connected to each of the other diagonal two corners of the transport member driven by the second driving device. It is equipped with a cord.

According to this elevator, the effect of the elevator according to the present invention can be obtained with a simple configuration for a generally rectangular conveying member.

In this elevator, if there is provided a single counterweight whose gravity acts in the direction in which the conveying member is lifted up through the first and second ropes, the lifting and lowering forces of the conveying member are provided. This is preferable because the movement of the transport member can be smoothly performed.

[0013] Alternatively, instead of a single counterweight in the elevator, a first counterweight whose gravity acts in a direction in which the conveying member is pulled up through the first cable, and a second counterweight through the second cable. It is preferable to provide a second counterweight on which the gravity acts in the direction in which the conveying member is lifted, since the separation of the counterweight further increases the degree of freedom in the arrangement of the drive system.

An elevator equipped with these counterweights includes a first drive sheave rotated by a first drive device and a second drive sheave rotated by a second drive device, one end of which is a transport member. Is wound around the first drive sheave, one end of which is wound around the second drive sheave connected to the transport member, and the other end of the first wire and the second wire. By connecting the other end of the strip to the above-described counterweight (single counterweight or first and second counterweights), the operation and effect of the present invention can be achieved in a traction-type elevator. The uniformization of the lifting and lowering force of the transport member is achieved by a simple configuration.

[0015] Further, there are provided a first winding drum rotated by the first driving device, a second winding drum rotated by the second driving device, a third cable, and a fourth cable. A first cable whose one end is connected to the conveying member is wound around the first winding drum after the other end is fixed to the first winding drum, and a second rope whose one end is connected to the conveying member. The other end is fixed to the second winding cylinder, and is wound around the second winding cylinder. The third cable is fixed to the first winding cylinder at one end, and the first cable is It is wound in the opposite direction to the winding direction of the strip,
The fourth cable is wound around the second winding drum in a direction opposite to the winding direction of the second cable after one end thereof is fixed, and the other end of the third cable and the fourth cable are In the elevator having the other end connected to the counterweight, the operation and effect of the present invention are exerted in the elevator of the winding drum type.

Still another elevator according to the present invention is a transport member for mounting an object to be lifted and lowered, a plurality of ropes connected to the transport member, and all the ropes are collectively moved in the lifting direction of the transport member. A biasing means for biasing, and a plurality of lifting and lowering means for raising and lowering the transporting member through each of the ropes, which is disposed at an intermediate point between the point of action of the biasing means and the transporting member in the cable. Drive units of the electric motor type and each cable is connected to each of two connection points on the transport member,
The center of an imaginary straight line connecting the connection points of the cables of one drive device and the center of the imaginary straight line connecting the connection points of the cables of the other drive device intersect approximately at the center of the transport member in plan view. It has been like that.

According to this elevator, since the drive device is separated, the size is reduced, and the degree of freedom of arrangement in the parking facility is expanded, so that the space in the parking facility can be effectively used. Further, a plurality of drive systems having drive devices are mechanically synchronized by the biasing means. That is, when the lifting speed of the transport member by one drive system is going to be faster than the lifting speed by the other drive system, the one drive system is less affected by the urging means and the burden weight is increased. The rotation speed of the motor decreases. Conversely, the rotation speeds of the motors of the other drive systems increase. As a result, a difference in the elevating speed is avoided, and the transport member can maintain a horizontal state.

Still another elevator of the present invention comprises a substantially rectangular transport member for mounting an object to be lifted, a third and a fourth electric motor type drive device for lifting and lowering the transport member, and A third cable connected to each of two adjacent corners of the conveying member driven by the driving device, and a fourth cable connected to each of the other two corners of the conveying member driven by the fourth driving device. , A single counterweight whose gravity acts in the direction in which the conveying member is pulled up via the third and fourth ropes.

According to this elevator, the effect of the elevator according to the present invention, in which the rope is attached to two adjacent corners by a simple configuration, is provided for a generally rectangular transport member.

This elevator further includes a third drive sheave rotated by a third drive and a fourth drive sheave rotated by a fourth drive, the third cable having one end connected to the transport member. The fourth wire is wound around the third drive sheave, one end of which is wound around the fourth drive sheave, and the other end of the third wire and the other end of the fourth wire are connected to the fourth drive sheave. By connecting to a single counterweight, the operation and effect of the present invention described above can be achieved in a traction-type elevator, and the ascending and descending forces of the transport member can be made uniform. This is preferable because the lifting and lowering operation becomes smooth.

Alternatively, in the above-mentioned elevator, the drive sheave is replaced with a winding drum, and a third winding drum rotated by a third driving device, a fourth winding drum rotated by a fourth driving device, and a fifth cable are provided. , A sixth cord, one end of which is fixed to the third cylinder and the other end of the third cable connected to the transport member is wound around the third cylinder, and one end thereof is connected to the transport member. The other end of the obtained fourth cable is fixed to the fourth cylinder, and then wrapped around the fourth cylinder. The fifth cable is fixed to one end of the third cylinder, and then the third cable is fixed. Winding in the direction opposite to the winding direction of the above, the sixth cable, after fixing one end thereof to the fourth winding drum, winding in the opposite direction to the winding direction of the fourth cable, the fifth cable By connecting the other end and the other end of the sixth cable to the single counterweight, the operation and effect of the present invention can be enhanced by the winding drum type elevator. So it is achieved in the preferred.

In the above elevator, at least one of the driving devices is a disk-shaped electric motor, and a drive sheave attached to the disk-shaped electric motor has a disk-shaped overall inside. An elevator in which a drum brake is concentrically arranged inside the above-mentioned disc-shaped electric motor, the drive unit and the sheave are light and compact overall. Because of this, the degree of freedom of arrangement is greatly improved. As a result, maintenance can be facilitated by attaching to a position that is easy to handle. Furthermore, it is possible to save the arrangement space.

The elevator-type multi-story parking facility according to the present invention includes any one of the above-mentioned elevators used for transporting vehicles, and a plurality of elevators for storing vehicles arranged along the hoistway of the elevator. The elevator drive device is disposed at a position where at least a part of the drive device enters a corner dead space in a specific parking space.

According to such a parking facility, the driving device is divided into a plurality of parts and arranged at a position to enter the dead space at the corner of the parking space. It can be used as

[0025]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the accompanying drawings, an elevator and an elevator-type multi-story parking facility of the present invention (hereinafter, referred to as an elevator-type multi-story parking facility) will be described.
An embodiment of the present invention will be described.

FIG. 1 (a) is a front sectional view showing an embodiment of the parking equipment of the present invention, and FIG. 1 (b) is a sectional view taken along line II of FIG. 1 (a).

A parking facility 1 shown in FIG. 1 lifts and lowers a vehicle by means of an elevator 2 to accommodate and leave the vehicle. The elevator 2 includes a substantially rectangular elevator frame 5 as a transport member that moves up and down in the center of the building 4 in plan view, a driving device (also called a hoisting device) 6 that moves up and down the elevator frame 5, and a counterweight 7. Have. The elevator 2 is connected to a counterweight 7 by a wire (or chain) 8 as a cable, and a driving device 6 rotates the motor 9 forward and reverse to move the elevator frame 5 up and down.

A plurality of upper and lower parking spaces 3 are arranged on both sides of the hoistway of the elevator 2. The parking facility 1 is configured such that a pallet 3a for mounting on a vehicle is placed in each parking space 3. However, the present invention is not limited to such a configuration, and any structure may be used as long as the vehicle can be raised and lowered by an elevator. . The elevator frame 5 moves up and down between the parking space groups 3 on both sides, moves to the designated parking space 3 floor, receives the pallet 3a, and transports it to the vehicle entry floor. In this parking facility 1, the entry floor is the lowest floor (the first floor). The elevator frame 5 is provided with a traverse device (not shown) for receiving and returning the pallet 3a.

The main difference between the parking facility 1 and the conventional parking facility is that there is no space (machine room) partitioned by a special floor for accommodating the driving device 6. Therefore, in the present parking facility 1, the top floor C which is conventionally used as a machine room is also used as the parking space 3. Such a structure is made possible by using two drive devices 6, which were conventionally one. That is, the drive system of the elevator 2 is divided into two systems.

FIG. 2 (a) is an enlarged view of a portion A in FIG. 1 (a), FIG. 2 (b) is an enlarged view of a portion B in FIG. 1 (b), and FIG. It is a top view of parking facilities.
In FIG. 2A, illustration of wires is omitted for easy understanding. By dividing the driving device 6 into two as shown in FIG. 2, each driving device 6 becomes small, and it is not necessary to concentrate necessary pulleys and sheaves in one place. Also, it is acceptable to make a corner cut inside the parking space provided that there is an appropriate gap for all the vehicles to be stored, and this portion can be said to be a dead space of the parking space. Therefore, if the drive devices are divided in this way, all or at least a part of each drive device 6 can be inserted into a corner of a specific parking space, for example, a dead space such as above or below a beam, and attached. As a result, as shown in FIG. 2, the upper part of the effective parking space 3b indicated by a two-dot chain line in the parking space 3 has a pyramid shape, but for example, even in a dead space which is a corner of the parking space on the top floor, the driving device 6 is not used. Fits well. There is no need to allow for additional output by splitting the drive 6 into two. The sum of the outputs of the two driving devices may be the output of one conventional driving device.

FIG. 3 shows an elevator 2 having two such driving devices 6. FIG. 3 is a perspective view showing the contents of FIG. In the elevator 2, the first driving device 6a operates two first wires 8a connected to two opposite corners of the elevator frame 5, and two second wires 8b connected to the other two opposite corners. This is operated by the second driving device 6b. In general, since the weight distribution of the elevator frame 5 in the radial direction from the centroid in plan view is substantially the same, a virtual straight line connecting the connection points (the two diagonal hanging points) of the first wire 8a to the elevator frame 5 is used. Substantially passes through the center of gravity of the elevator frame 5, and a virtual straight line connecting the connection points of the second wires 8 b to the elevator frame 5 also substantially passes through the center of gravity of the elevator frame 5. Also, the first wire 8
a, the center of gravity is located at the center between the suspension points
The center of gravity is located at the center between the hanging points b. Thus, the center of gravity of the elevator frame 5 is the common center point of the connection of both drive trains to the elevator frame 5. Therefore, the first drive system and the second drive system are restricted at the intersection of the virtual straight line connecting the connection points of the first wires 8a and the virtual straight line connecting the connection points of the second wires 8b in the elevator frame 5. (Mechanically synchronized).

Each of the driving devices 6a and 6b has a motor 9 and a driving sheave 10. The two first wires 8a are put together by a plurality of first turning pulleys 11a and wound around the first drive sheave 10a. The two second wires 8b are put together by a plurality of second turning pulleys 11b and wound around the second drive sheave 10b. The first wire 8a and the second wire 8b are collectively attached to the single counterweight 7 via the other first and second diverting pulleys 11a and 11b. Since the ends of both wires 8a and 8b are collectively attached to one place of the counterweight 7, the level (ground height) of the ends of both wires 8a and 8b does not differ even if the counterweight 7 is inclined. When attaching both wires 8a, 8b to the counterweight 7, the wires 8a, 8b
The tension may be adjusted so that the elevator frame 5 is horizontal.

In such an elevator 2, it is not necessary to synchronize the motors of the two driving devices 6 with a special control device.
This is because the rotation speed of the electric motor generally decreases as the load applied thereto increases, and the rotation speed increases as the load applied decreases. Therefore, in the two drive systems mechanically constrained at one point, the two drive devices 6a, 6
b, when the lifting speed (or the lowering speed) of the elevator frame is going to be different, for example, when the lifting speed of the first driving device 6a is going to be faster than the second driving device 6b, the second wire 8b bears a load. Since the weight is reduced, it tends to sag between the elevator frame 5 and the second drive sheave 10b. Then, the rotation speed of the motor (second motor) 9b of the second driving device 6b tends to increase. Conversely, since the weight of the first wire 8a increases, the tension between the elevator frame 5 and the first drive sheave 10a tends to increase. Then, the rotation speed of the motor (first motor) 9a of the first driving device 6a tends to decrease. As a result, the lifting speed (or the lowering speed) of both the driving devices 6a and 6b becomes the same. That is, both drive systems are automatically synchronized, and the elevator frame 5 maintains a horizontal state. In such an elevator, the motors 9 of the two driving devices 6a, 6b
It is not necessary to make the outputs of a and 9b the same. Both 9a, 9
It is sufficient that the total output of b is sufficient to move up and down the elevator frame 5. From the above, the degree of freedom in designing and manufacturing is greatly expanded.

When the elevator frame 5 is lowered, if the speed at which the counterweight 7 is lifted is to be different, the wire having the higher counterweight lifting speed tends to sag between the drive sheave and the elevator frame. The same mechanism automatically equalizes the speed at which the counterweight 7 is pulled up.

Although the present elevator 2 uses a single counterweight 7, the present invention is not limited to such a configuration. For example, like the elevators 12 and 22 shown in FIGS. 4 and 5, counterweights 7a and 7b may be attached to each of the driving devices 6a and 6b. Even in such an elevator, the lifting and lowering operations of the elevator frame 5 are synchronized by the same mechanism as that in the elevator 2. In this case, both counterweights 7a, 7b
The levels do not need to match. If the counterweights are separated in this manner, the driving devices 6a and 6b can be separately arranged on both sides of the elevator frame 5 as in the elevator 22 shown in FIG. Of course, it can be separately arranged at any position, and the driving device 6a,
The degree of freedom of arrangement of 6b is increased.

The elevators 2, 12, 22 shown in FIGS.
As long as the two drive systems in the elevator frame 5 are mechanically synchronized as described above, the same operation and effect can be obtained not only by the traction system (FIGS. 2 to 5) but also by employing the winding system. . That is, the elevator 32 shown in FIG.
As described above, the winding drum 13 may be used instead of the drive sheave 10 and the counterweights 7, 7a, 7b in FIGS. 6, the same members as those in FIGS. 2 to 5 are denoted by the same reference numerals, and description thereof will be omitted. The first drive unit 6a is provided with a first winding cylinder 13a, and the second drive unit 6b is provided with a second winding cylinder 13b. A first wire 8a is wound around the first winding cylinder 13a a plurality of times with its end fixed. 2nd cylinder 1
A second wire 8b is wound a plurality of times around 3b with its end fixed. The elevator frame 5 is moved up and down by rotating the winding drum 13 forward and backward. This elevator 32 is also the elevator 1 described above.
It is easy to see that the lifting and lowering operations are synchronized by the same mechanism as that of 2,22.

As shown by a two-dot chain line in FIG.
A counterweight 7a, so that a rotational force in the direction opposite to the rotational force direction due to the weight of the elevator frame 5 is applied
7b may be attached. By doing so, the lifting force and the lowering force of the elevator frame 5 are made uniform.

In the embodiment described above, the elevator frame 5 has a substantially rectangular shape, and the wires are connected to the two opposing corners. However, the present invention is not limited to such a configuration. In the one in which the constraint points of the two drive systems are present in the elevator frame, regardless of the planar view shape of the elevator frame, a virtual straight line connecting the connection points of one wire and a virtual straight line connecting the connection points of the other wires May be connected so as to intersect within the outline frame range of the elevator frame in plan view. At this time, the number of wires is not limited to two, and may be three or more.

The elevators 2, 12, 2 shown in FIGS.
Reference numerals 2 and 32 indicate that the restraining points of the two drive systems exist in the elevator frame 5, but the restraining points may be provided on the counterweight side.

FIG. 7 shows such an elevator 42. In the elevator 42, the third driving device 16a operates two third wires 15a connected to two adjacent corners of the elevator frame 5, and connects two fourth wires 15b connected to the other two opposite corners. This is operated by the fourth driving device 16b. Therefore, in each of the wires 15a and 15b, the two virtual straight lines connecting the two connection points in the elevator frame 5 do not intersect, and are not synchronized on the elevator side. Only when both wires 15a and 15b are synchronized can the elevator frame 5 be moved up and down in a horizontal state. Therefore, in this elevator 42, both wires 15a,
15b is restrained (mechanically synchronized) by a single counterweight 7. It is as follows.

Each of the driving devices 16a and 16b has a motor 19 and a driving sheave 18. Two third wires 15a
Are integrated by a plurality of third diverting pulleys 17a and are wound around a third drive sheave 18a. The two fourth wires 15b are combined by a plurality of fourth turning pulleys 17b, and are wound around the fourth drive sheave 18b. The third wire 15a and the fourth wire 15b are collectively attached to the single counterweight 7 via the other third and fourth deflecting pulleys 17a and 17b. Since the ends of both wires 15a and 15b are collectively attached to one place of the counterweight 7, even if the counterweight 7 is inclined, both wires 15a and 15b are attached.
The levels at the ends of a and 15b are not different. Also, especially if the ends of both wires do not have to be attached to one place,
It is sufficient that the levels at the ends of both wires do not differ. For example, the counterweight 7 is vertically moved up and down without tilting left and right by a vertical guide rail 7c or the like. In short, the level (height position) of both wires on the counterweight side should not be different due to the displacement of the counterweight 7. Then, both wires 15a and 15b are connected to the counterweight 7
At the time of mounting, the elevator frame 5 is adjusted to be horizontal with the wires 15a and 15b tensioned.

In the above two drive systems mechanically constrained at one point in the single counterweight 7, when there is a difference in the lifting speed of the elevator frame between the two drive devices 16a and 16b, for example, When the lifting speed of the third driving device 16a is going to be faster than that of the fourth driving device 16b, the third wire 15a tends to sag between the third driving sheave 18a and the counterweight 7. Then, the load of the third drive device 16a increases because the weight of the counterweight 7 does not help the elevator frame being lifted, so that the load increases and the rotation speed of the third motor 19a of the third drive device 16a tends to decrease. Therefore, the slack of the third wire 15a between the third drive sheave 18a and the counterweight 7 is eliminated, and the pulling speeds of both the driving devices 16a and 16b become the same.
That is, both drive systems are automatically synchronized. Also in this elevator, the motors 19 of the two driving devices 16a and 16b are used.
It is not necessary to make the outputs of a and 19b the same. Both 19
It suffices if the total output of a and 19b is sufficient to move up and down the elevator frame 5. From the above, the degree of freedom in designing and manufacturing is greatly expanded.

When the elevator frame 5 is lowered, if the speed at which the counterweight 7 is lifted is to be different, the wire with the slower lifting speed tends to sag between the drive sheave and the counterweight 7, so the same as above. The mechanism automatically raises (synchronizes) the speed at which the counterweight 7 is pulled up. As a result, the elevator frame 5 maintains a horizontal state.

As in the case of an elevator 42 shown in FIG. 7, if both drive systems are mechanically synchronized in a single counterweight 7, a traction system (FIG. 7)
However, the same operation and effect can be obtained even if the winding drum system is adopted.

That is, like the elevator 52 shown in FIG. 8, the winding drum 20 may be used instead of the drive sheave 18 in FIG. In FIG. 8, the same members as those in FIG. 7 are denoted by the same reference numerals, and description thereof will be omitted. The third driving device 16a is provided with a third winding drum 20a, and the fourth driving device 16b is provided with a fourth winding drum 20b. A third wire 15a is wound around the third winding cylinder 20a a plurality of times with its end fixed. A fourth wire 15b is wound around the fourth winding cylinder 20b a plurality of times with its end fixed.

As shown in the figure, a single counterweight 7 is attached to both winding cylinders 20a and 20b. That is, the third winding drum 20a applies a rotational force in a direction opposite to the rotational force direction due to the weight of the elevator frame 5,
The fifth weight 21 a is connected to the counterweight 7. The fourth winding cylinder 20a is also provided with the elevator frame 5
Is connected to the counterweight 7 by the sixth wire 21b so that a rotational force in a direction opposite to the rotational force direction due to the weight of the member is applied. It can be easily understood that the elevator 52 is also synchronized in the elevating operation by the same mechanism as that of the elevator 42 described above.

The elevators 42, 5 shown in FIGS.
2, the elevator frame 5 has a substantially rectangular shape, and wires are connected to two adjacent corners. However, the present invention is not limited to such a configuration. In the case where the constraint points of the two drive systems are present in a single counterweight, the wires may be connected to two locations near the sides of the elevator frame regardless of the shape of the elevator frame in plan view. The number of wires may be two or more.

Among the elevators described above, those using a single counterweight 2, 42 and 52,
It is not necessary for the two separate drives to be adjacent, in particular in the vicinity of a single counterweight. The driving devices may be suitably separated from each other so as to obtain the effect of separating and miniaturizing the driving devices. It is easy to use a diverting pulley to run a wire from a remote drive to a single counterweight.

FIG. 9 shows another parking facility 23. The parking facility 23 is an upper-entering parking facility having a vehicle accommodation space formed underground. In this parking facility 23 as well, the driving device 6 (16) is divided into a plurality of vehicles. Then, the miniaturized drive device 6 (1)
6) is attached to a corner of the parking space, that is, above or below a beam. As a result, it is not necessary to form a space (machine room) partitioned by a special floor. The space S, which has conventionally been a machine room, can be effectively used as a residence or the like.

Of the above-described embodiments, those using the drive sheaves 10 and 18 are shown in FIGS.
As described in 7), a general-purpose cylindrical drive motor having a drive sheave attached to an output shaft via a reduction gear is used. However, a thin drive device 24 shown in FIG. 10 can be used instead. This drive 24
In this embodiment, a drive sheave 26 is integrated integrally with a disk-shaped servo motor 25 adjacent thereto. The motor 25 includes a disc-shaped rotor (not shown) and a ring-shaped stator disposed concentrically with the rotor. Drive sheave 26
A groove 27 around which a wire is wound is formed in the outer periphery of the drive sheave 26, and a reduction mechanism 28 which is formed in a disk shape as a whole and utilizes, for example, a planetary gear is incorporated concentrically inside the drive sheave 26. ing. That is, the sun gear 28a attached to the output shaft of the motor 25 and the drive sheave 2
6 is composed of an internal gear 28b concentrically formed on the inner peripheral surface and an intermediate small gear 28c disposed between these gears. An encoder 29 is attached to a drive shaft of the motor 25. Motor 2
5, a drum brake (not shown) acting on the inner surface of the housing is provided. The driving device 24 is a known device, for example, a model ED1006 manufactured by Teijin Machinery Co., Ltd.
It has been known. Of course, the type of the driving device can be selected according to the use of the elevator weight, the elevator speed, and the like.

The driving device 24 has, for example, a length of about 200 mm, a maximum outer diameter of about 584 mm, and a weight of about 20 mm.
0 kg. The driving devices 6 and 16 of the same output shown in FIGS. 3 to 5 and 7 have a length of 1450 mm, a maximum outer diameter of 554 mm, and are much lighter and smaller than a weight of 500 kg. Particularly, since the weight and the axial length of the motor are small, the following advantages can be obtained.

For example, as shown in FIG.
4 can be installed on a beam of the parking facility 1 with only the drive sheave 26 projecting sideways from the beam so that the wires 8a and 8b can be wound around the beam. This is possible because the axial length of the motor is short. The driving device 24 has a length of 200 as described above.
Since it is about mm, it can be sufficiently mounted and fixed to a beam made of, for example, an H-shaped steel having a width of 200 mm without substantially protruding. For this reason, it is not necessary to particularly install the vehicle at the corner of the parking space 3 shown in FIG. As a result, the degree of freedom of the arrangement of the driving device 24 is much improved as compared with the driving devices 6 and 16 shown in FIGS. FIG.
The other configuration shown in FIG. 1 is the same as that in FIG.

Further, as shown in FIG.
It is also possible to install only the lowermost floor of the parking facility 1. For this purpose, an additional pulley 30 for deflecting the direction of the wires 8a, 8b is provided. It is difficult to install the driving devices 6 and 16 in FIGS. This is because there is no installation space in existing parking facilities due to its large volume.

By installing the driving device 24 on the floor as described above, maintenance of the driving device is facilitated.
In addition, it is easy to attach not only to the floor but also to a beam on an arbitrary floor of the parking facility so as not to interfere with the elevation of the pallet. The other configuration shown in FIG. 12 is the same as that in FIG. 3, and thus the same reference numerals are given and the description will be omitted.

[0055]

According to the present invention, since the driving device is separated, the size is reduced, and the degree of freedom of arrangement in the parking facility is increased, so that the space in the parking facility can be effectively used. Furthermore, since the drive system including one drive device and the drive system including the other drive device are mechanically synchronized, the transport member such as the elevator frame can maintain a horizontal state without using a special control device. it can.
