FIELD OF THE INVENTION The present invention relates to elevator equipment.

[0002]

2. Description of the Related Art An elevator apparatus attached to a building or the like comprises an elevator hoistway provided along the vertical direction of the building and a cage for accommodating a user. The cage is suspended in the elevator hoistway by a wire cable, and the wire cable is wound up and pulled up and down in the elevator hoistway to the floor where the user called. Move vertically to transport users to the desired floor.

In such an elevator system, in order to increase the amount of transportation per unit time of the user and per unit area of the building, the speed of raising and lowering the cage is increased or the number of elevator elevating passages is increased. There is a need. However, there is a limit to the raising and lowering speed of the cage, and when the number of elevator raising and lowering passages is increased, the use area of each floor of the building is reduced, so the space inside the building cannot be used effectively. There is a problem.

Further, in an ultra-high-rise building, the weight of the wire cable becomes excessively large, which causes structural restrictions and makes it impossible to install the wire cable type elevator.

For this reason, a plurality of cages are housed in an elevator hoisting passage in which the ascending passage and the descending passage are connected by a traverse passage, and the drive thereof does not depend on a wire cable,
An elevator apparatus that uses a linear motor has been proposed.

In this elevator device, since a plurality of cages can be moved up and down and traversed, it is possible to overtake the preceding cage as required, and it is possible for the user to per unit time and per unit area of the building. The amount of transportation can be increased.

However, in the transverse passage connecting the ascending passage and the descending passage, the connecting structure is complicated in order to smoothly traverse the cage. Further, since the cage retains the level state of the cage itself, it can traverse only at a right angle and can be retracted from the route, so that it takes a predetermined time to lead another cage ahead. Further, the elevator facility becomes large-scaled, the installation cost and the power consumption required linearly become enormous, the running cost is high, and the operation control system thereof is complicated.

[0008]

SUMMARY OF THE INVENTION In consideration of the above facts, the present invention has a simple structure and control, allows the cage to be quickly withdrawn from the elevator hoistway, and can effectively utilize the building space and improve transportation capacity. It is an object of the present invention to provide an elevator apparatus capable of achieving the above.

[0009]

SUMMARY OF THE INVENTION An elevator apparatus according to the present invention comprises a loop-shaped cage passage in which upper and lower ends of an ascending passage and a descending passage communicate with each other, and a chamber for the ascending passage and the descending passage. A stage that is disposed inside, in which the cage can be retracted from the ascending passage and the descending passage, a guide rail that extends along the cage passage and a rack is formed along an extending direction, and the guide. A plurality of cages that can move along rails, a guide rail for evacuation that extends from the guide rail side into the stage and that can move the cages, and a rack is formed along the extending direction; and the rack. Gears that mesh with each other, a drive device that rotates the gears, leveling means that intervenes between the drive device and the cage to swingably support the cage and maintain the horizontal posture of the cage, and A first auxiliary guide rail provided at a joint portion between the guide rail and the evacuation guide rail and connecting the guide rails to each other, and a second auxiliary guide rail connecting the guide rail to the evacuation guide rail. And a switching table that brings the first auxiliary guide rail or the second auxiliary guide rail into a connected state by being rotated.

[0010]

In the elevator apparatus according to the above-mentioned structure, the plurality of cages circulates in the loop-shaped cage passage in a certain direction, so that it is easier to control as compared with the reciprocating movement, and the transport amount of the user per unit time is reduced. The space in the building can be effectively used while being improved.

If necessary, the switching table provided at the joint between the guide rail and the retracting guide rail is rotated to rotate the switching table from the first auxiliary guide rail connecting the guide rails to the second auxiliary guide rail. Switch to the guide rail. As a result, the guide rail and the retracting guide rail are connected, and the cage can be retracted to the stage through the second auxiliary guide rail. As a result, the user can move the cage in and out of the car to the desired floor ahead of time, and reduce the number of cages that move the guide rails to save energy during late night hours. You can

The movement of the cage is realized by a rack formed on the guide rail and the evacuation guide rail along the extending direction thereof, and a gear meshing with the rack. The gear is driven by a drive device to move the cage up and down while retracting the cage to the stage while meshing with the rack of the guide rail or the guide rail for retreat. Therefore, it can be installed even in super high-rise buildings, and
Since the structure is simple, it does not require large-scale equipment like a linear motor.

Since the cage is swingably suspended by the leveling means in this drive device, the cage swings regardless of the inclination of the drive device, and the horizontal posture of the cage is always maintained. Therefore, even when the cage moves obliquely from the guide rails arranged in the vertical direction to the retracting guide rails arranged in the lateral direction, the cage does not tilt due to the principle of the pendulum, and the user can safely operate. Can be transported to the desired floor.

And are provided.

Ascending passage 14 and descending passage 2 shown in FIG.
As shown in FIG. 6, a power supply line 68 is arranged near the center of the 0 and the escape passage 26 along the passage. The cage 18 is provided with a current collecting shoe 66 corresponding to the power supply line 68 and in contact with the power supply line 68. Electric power is supplied to the cage 18 from a power supply line 68 via the current collecting shoe 66, and is used for lighting in the cage 18, opening and closing the doors 62 and 64, and operating the drive motor 44 and the like. An information cable 70 is arranged along the passage near the power supply line 68. The information cable 70 is composed of a leaky coaxial cable, which radiates a signal being transmitted as a leak magnetic flux to the surroundings and receives a signal which will be described later from the cage 18.
An antenna 72 for receiving a signal leaked from the information cable 70 is attached to the cage 18, which enables communication between the inside and outside of the cage 18 and detects the position of the cage 18.

As shown in FIG. 8, the information cable 70 is connected to the control device 80. The position information of each cage 18 detected via the information cable 70 is input to the control device 80. An operation panel 74 operated by a user is attached in the cage 18. When the destination sky lobby is designated by the user operating the operation panel 74, the destination is transmitted as a signal from the above-mentioned transmitting device and input to the control device 80 via the information cable 70.

Further, a call button 78 for allowing a user of the elevator device to call the cage 18 is attached to the boarding gate 28 of each sky lobby S. Each call button 78 is connected to the control device 80. The control device 80 detects the call of the cage 18 from the user by operating the call button 78.

The operation of the invention according to this embodiment will be described below. In this elevator apparatus, it is premised that the user gets on and off the cage 18 from the boarding port 28 of the descending passage 20 when descending, and from the boarding port 28 of the ascending passage 14 when ascending. Therefore, the control system is simplified.

Control when the cage 18 ascends to the target sky lobby S along the elevating guide rails 22 will be described with reference to the block diagram of FIG. 8 and the flow chart of FIG.

In step 100, it is determined whether or not there is an instruction to move the cage 18. The destination of the sky lobby S is designated by operating the cage 18 by the call button 78 or by operating the operation panel 74 by the user who is in the cage 18. Cage 18
If there is no instruction to move, the step 100 is repeated until the cage 18 is called.

If there is an instruction to move up, step 10
In step 2, it is determined whether or not there is a preceding cage 18 that is in a stopped state in the movement route that raises the cage 18 to the target sky lobby. Cage 1 ahead and in a stopped state
If there is eight, in step 104, the cage 18 that precedes and is in the stopped state is moved to the nearest escape passage 26 located on the upper floor.
Evacuate to. That is, the turntable 112 disposed on the lower floor of the destination sky lobby S is rotated, and the elevating guide rail 22 and the evacuation guide rail 30 are connected by the curved auxiliary guide rail 116. In this state, when the cage 18 that precedes and is in a stopped state is raised, the cage 18 passes through the auxiliary guide rail 116, and the cage 18 moves upward.
To the evacuation passage 26.

If it is determined in step 102 that there is no preceding cage 18 in a stopped state, step 1
Move to 06.

In step 106, an ascending route to the destination sky lobby S is formed. That is, the turntable 112 in the middle of the ascending path is rotated so that the upper and lower portions of the elevating guide rail 22 are linearly guided by the auxiliary guide rail 1.
I will contact you at 14. On the other hand, the evacuation guide rail 30 and the elevating guide rail 22 connected to the destination sky lobby S
And the turntable 112 are rotated, and they are connected to each other via a curved auxiliary guide rail 116.

Next, in step 108, the drive motor 44 rotates the gear 46 to raise the cage 18 while meshing with the rack L to raise and lower the guide rail 22.
To the evacuation guide rail 30 and to the target sky lobby S. When the cage 18 moves from the elevating guide rails 22 to the retracting guide rails 30, the cage 18 skews, but only the gear 18 rotates due to meshing with the rack L, and the cage 18 moves.
Maintains a horizontal posture without tilting due to the pendulum principle. Therefore, the boarding user is not anxious. Next, in step 110, the door opening / closing drive device 98 opens the right door 62 based on the rising instruction signal in step 100.

As described above, since the elevator apparatus according to this embodiment has a simple structure and movement control, the construction cost can be reduced. Further, since it is possible to continuously move from the elevating guide rail 22 to the evacuation guide rail 30, the transporting power is improved. In addition, the cage 18 includes
4, the traverse passage 16 and the descending passage 20 are circulated, so that the user can reciprocate when the flow of the user tends to be in one direction, such as when going to work, at lunch, or when leaving the office. The user can be handled efficiently as compared with an elevator apparatus that operates. Further, even if the drive motor 44 stops due to a power failure or the like, the stopper 50 stops the rotation of the gear 46, so that the safety of the user is ensured.

A linear motor may be used as the rotating means of the evacuation guide rail 122. Further, as described above, the cage 18 can be easily evacuated to the evacuation passage 26, so that it is possible to change the traveling time of the cage 18 according to the use time zone, such as limited express, express, and obscure. That is, for example, one for every 10 minutes, the cage 18 for express trains is set in advance, and the cage 18 for the express train is moved up and down from the ground to the top floor non-stop. The evacuation path 26 is evacuated. It should be noted that the display of limited express, express, and slow train is shown on the electronic bulletin board arranged in the sky lobby S, and a time table is installed in each sky lobby S, similar to the operation table of a normal train.

As described above, by providing the cages having different traveling times, it can be effectively used as a transportation device in an ultra-high-rise building which is expected to be constructed in the future.

[0036]

Since the elevator drive apparatus according to the present invention has the above-described structure, the structure and control are simple, the cage can be quickly retracted from the elevator hoistway, and the effective use of the building space and the improvement of the transportation force can be achieved. Can be achieved.
