DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator system.

[0002]

2. Description of the Related Art An elevator apparatus mounted on a building or the like is composed of an elevator elevating passage provided along a vertical direction of the building and a cage for accommodating a user. The cage is suspended in the elevator passage by wire cables, and is lifted and lowered in the elevator passage by winding and pulling out of the wire cable, to the floor where the call was made by the user. Move vertically to transport the user to the desired floor.

In such an elevator apparatus, in order to increase the amount of transportation per unit time and per unit area of the building, the elevator speed is increased or the number of elevator elevator passages is increased. There is a need. However, there is a limit to the speed at which the cage can be raised and lowered, and when the number of elevator elevator passages is increased, the space used in each floor of the building decreases, so that the space in the building cannot be used effectively. There is a problem.

[0004] Furthermore, 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 a wire cable type elevator.

For this reason, a plurality of cages are accommodated in an elevator elevating passage in which an ascending passage and a descending passage are connected by a traversing passage.
2. Description of the Related Art Elevator devices using a linear motor have been proposed.

[0006] In this elevator device, a plurality of cages can be moved up and down and traverse, so that it is possible to pass ahead of the preceding cage if necessary. The transport amount can be increased.

[0007] However, in the traversing passage connecting the ascending passage and the descending passage, the connecting structure is complicated in order to smoothly traverse the cage. In addition, since the car does not evacuate from the line because it only crosses at a right angle in order to maintain the level state of the car itself, it takes a predetermined time to move another car ahead. Further, the elevator equipment is large, the installation cost and the power consumption required for linear operation are enormous, the running cost is increased, and the operation control system is complicated.

[0008]

SUMMARY OF THE INVENTION In consideration of the above facts, the present invention has a simple structure and control, allows a cage to be quickly evacuated from an elevator elevating passage, and effectively uses a building space and improves a transportation capacity. It is an object of the present invention to provide an elevator apparatus capable of achieving the following.

[0009]

According to the present invention, there is provided a loop-shaped cage passage in which upper and lower ends of an ascending passage and a descending passage communicate with each other, and an indoor side between the ascending passage and the descending passage. A stage in which the cage can retreat from the ascending passage and the descending passage, a pair of guide rails continuously laid along the cage passage, and a plurality of cages movable along the guide rails And an evacuation guide rail continuously extending from the guide rail side into the stage and allowing the cage to move, and guiding the cage to be movable between the guide rail and the evacuation guide rail. A switching means, formed along the extending direction of the guide rail and the evacuation guide rail, facing each other;
And a rack that extends in the direction in which the cage is stretched.
A pair of gears meshing with a gear, a driving device for rotating the gears, and a leveling means interposed between the driving device and the cage so as to swingably support the cage and maintain a horizontal posture of the cage, And a restricting means provided along the circumferential direction on both surfaces of the gear to restrict contact of the gear in the axial direction by contacting the guide rail and the retreating guide rail.

[0010]

[0011]

[0012]

[0013]

In the elevator apparatus according to the above configuration, since a plurality of cages circulate and move in a loop-shaped cage passage in a fixed direction, the control is easier than the reciprocating movement, and the amount of transport of the user per unit time is reduced. The space in the building can be effectively used and the space in the building can be effectively used.

Further, if necessary, the switching means can be driven to guide the cage from the guide rail to the evacuation guide rail, and the cage can be retracted to the stage. As a result, it is possible to move the cage on which the user gets on and off to the target floor in advance, and to reduce energy consumption by reducing the number of cages that move the guide rails at midnight, etc. Can be.

The cage is moved by a pair of guide rails and evacuation guide rails, the racks being formed along the extending direction thereof and facing each other, and a cage extending direction.
This is realized by a pair of gears that mesh with the overhang rack . In this way, a pair of overhanging cages
The gears mesh with the rack, thereby
Regardless of the gear, the gear does not come off the rack. Also,
The gears are driven by a driving device to move the cage up and down while retracting the cage on the stage while meshing with a rack of guide rails or evacuation guide rails.
Therefore, it can be installed even in an ultra-high-rise building, and the structure is simple, so that large-scale equipment such as a linear motor is not required.

In this drive device, the cage is suspended swingably by the leveling means, so that the cage swings irrespective 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 vertically arranged guide rails to the evacuation guide rails arranged horizontally, the cage does not tilt due to the principle of the pendulum, and the user can safely move. Can be transported to the desired floor.

[0017]

Further, since the run-out of the gear in the axial direction is restricted by the restricting means, the user does not feel discomfort due to the lateral run-out of the cage.

Further, a call button 78 for a user of the elevator apparatus 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. When the call button 78 is operated, the control device 80 detects a call of the cage 18 from the user.

Hereinafter, the operation of the elevator apparatus according to the present embodiment will be described. 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.

Here, control when the cage 18 moves up 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 flowchart of FIG.

In step 100, it is determined whether an instruction to move the cage 18 has been given. The cage 18 is operated by the call button 78 or the user who has entered the cage 18 operates the operation panel 74 to specify the destination sky lobby S. Cage 18
If there is no movement instruction, step 100 is repeated until the cage 18 is called.

If there is an ascending instruction, step 10
At 2, it is determined whether or not there is a preceding and stopped cage 18 in the moving route for raising the cage 18 to the target sky lobby. Cage 1 that is ahead and stopped
If there is, at step 104, the cage 18 which is in the preceding stopped state is moved to the nearest evacuation passage 26 located on the upper floor.
Evacuate to That is, the electromagnet 34 disposed on the lower floor from the destination sky lobby S is turned on and the electromagnet 36 is turned off, and the elevating guide rail 22 is shut off by the switching plate 32 below the evacuation guide rail 30. In this state, when the cage 18 in the stopped state is moved up,
The cage 18 is guided by the switching plate 32 and retracts from the ascending passage 14 to the evacuation passage 26.

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

In this step 106, an ascending route to the destination sky lobby S is formed. That is, the evacuation guide rail 30 in the middle of the ascending path is cut off by the switching plate 32 by turning off the electromagnet 34 and turning on the electromagnet 36. On the other hand, the switching plate 3 below the evacuation guide rail connected to the destination sky lobby S
The guide rail 22 for raising and lowering is shut off at 2.

Next, in step 108, the gear 46 is rotated by the drive motor 44, and the cage 18 is raised while being engaged with the rack L.
To the evacuation guide rail 30 and to the target sky lobby S. When the cage 18 moves from the elevating guide rail 22 to the evacuation guide rail 30, the cage 18 is skewed, but only the gear 18 is rotated by engagement with the rack L, and the cage 18 is rotated.
Maintains a horizontal posture without tilting due to the principle of the pendulum. For this reason, there is no fear of giving the boarding user. Next, in step 110, the right door 62 is opened by the door opening / closing drive device 98 based on the rising instruction signal in step 100.

As described above, since the structure and movement control of the elevator apparatus according to the present embodiment are simple, the construction cost can be reduced. In addition, since it is possible to continuously move from the elevating guide rail 22 to the evacuation guide rail 30, the transporting power is improved. Further, the cage 18 is provided with the ascending passage 1.
4. Since it circulates in the traversing passage 16 and the descending passage 20, when the flow of the user tends to be in one direction, such as when going to work, lunch, or leaving the office, the reciprocating movement The user can be handled more efficiently as compared with the elevator device that performs the operation. In addition, 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.

Although the electromagnets 34 and 36 are used as the rotating means of the switching plate 32, the present invention is not limited to this. A motor is provided at the center of rotation of the switching plate 32 and is rotated. You may do so.

Further, as described above, since the cage 18 can be easily retreated to the retreat passage 26, the cage 1 can be easily operated according to the use time period, such as limited express, express, and slow.
8 can also change the moving time. That is, for example, one cage for the express train in advance, such as one train every 10 minutes.
8 is set, the elevator is raised and lowered from the ground to the top floor in a non-stop manner, and the other cages 18 are evacuated to the evacuation passage 26 until the express cage 18 passes. In addition, the display of an express, an express, and a slow train is shown on the electric bulletin board arranged in the sky lobby S, and a time table is installed in each sky lobby S in the same manner as a normal train operation table.

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

[0043]

Since the elevator 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 elevating passage, and the effective use of the building space and the improvement of the transportation capacity are achieved. Can be planned.
