Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a so-called one-shaft / multi-cage type lifting device having a plurality of cages in one hoistway, and a method of operating the same.

[0002]

2. Description of the Related Art Conventionally, as this type of lifting device, there is a linear synchronous motor type device as shown in FIG. In FIG. 6, 1 is an ascending / descending hoistway, 2 is a descending hoistway, and lateral moving paths 3a, 3b for communication are formed between the upper ends and the lower ends thereof. A ring-shaped coil group 4 is vertically stacked in both hoistways 1 and 2, and a superconducting magnetic field generator 6 is attached to a cage 5. Thus, the cage 5 is moved up and down to achieve the intended purpose, for example, between the A floor and the Z floor of the building frame. Also, semi-annular coils 7 are attached to the left and right ends of the lateral movement paths 3a and 3b so that the cage 5 can be moved up and down by a linear synchronous motor which is also composed of the magnetic field generator 6 of the cage 5. Is becoming A horizontal moving carriage 8 is installed on the upper and lower horizontal moving paths 3a and 3b, and a cage 5 is mounted on the moving vehicle 8 so as to move between the hoistways 1 and 2.

Hereinafter, the cage 5 is moved from the hoistway 1 side to the hoistway 2
The procedure for moving to the side will be described. First, the cage 5 is moved laterally 3a by the linear synchronous motor described above.
Up to. At this time, the laterally moving carriage 8 moves along the laterally moving path 3a.
Waiting in the middle of the. Then, when the cage 5 is completely lifted, the lateral movement carriage 8 travels directly below the cage 5. After that, the cage 5 is lowered and the lateral movement carriage 8 is used.
Then, the cage 5 is transported to the hoistway 2 side. Next, the cage 5 is driven by the linear synchronous motor on the hoistway 2 side.
Is temporarily lifted, the lateral movement carriage 8 is made to stand by at the center of the lateral movement path 3a, and then the cage 5 is lowered into the hoistway 2.

[0004]

However, in the conventional circulation type lifting device as described above, since a lateral moving path and a lateral moving device such as a carriage are required, the space required and the cost are increased. However, there is a problem in that the driving operation becomes complicated and the operation becomes complicated.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an elevating device and a method of operating the same which can save space and simplify the operation.

[0006]

In order to achieve the above object, an elevator according to the present invention is provided with a plurality of cages in one hoistway, and the cages are provided above and below the hoistway. The evacuation area is provided. In addition, the operation method according to the present invention is such that one set of the elevating and lowering device 2 sets as one set and one of them goes up and the other goes down, and when each cage has reached the upper part and the lower part, the reverse operation is performed. One of them is going down, and the other is going up, respectively, and the lifting device 3
With the above formulas as one set, one goes up and the other goes down sequentially, and when all these cages arrive at the upper and lower parts, this time reversely go down, respectively It is characterized by the fact that the rest of the train operates only upward or downward while operating.

[0007]

According to the lifting device, a plurality of cages can be operated in a normal straight hoistway, and space can be saved. According to the operation method, the same service is provided for both going up and going down.

[0008]

An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a lifting device in which a plurality of (two in the figure) cages 11a and 11b are installed in one hoistway 10. An upper evacuation area 12 is provided above the Z floor, which is the uppermost floor of the building structure, at the upper part of the hoistway 10, and when the lower cage 11b is at the Z floor entry / exit service position, the upper evacuation area is provided. The cage 11a can be evacuated to the upper evacuation area 12. Further, at the bottom of the hoistway 10, a lower evacuation area 13 is provided below the A floor, which is the lowest floor of the building frame, and when the upper cage 11a is at the A floor entry / exit service position, Lower cage 11
b can be evacuated to the lower evacuation area 13.

Due to the above structure, the operation is performed as follows. First, starting from the state of being on the upper part of the hoistway 10, the car 11b is operated downward after getting on and off the cage 11b. After that, the cage 11a is moved to the position of the Z floor, and after getting on, the car is operated downward. At this time, in general, the train is operated at a predetermined service interval. After the cage 11b arrives at the A floor and the customer gets off, it is evacuated to the lower evacuation area 13. Then, the cage 11a arrives and the customer gets off. And this time, it will be operated as an uphill, but it will be operated sequentially by the same method as described above.

FIG. 2 shows an example in which the two lifting devices of FIG. 1 are installed as one set. According to this, one hoistway 10
From the state where the cages 11a and 11b are located above the a and the cages 11a and 11b are located below the other hoistway 10b,
One hoistway 10a runs downwards, and the other hoistway 10b runs upwards. After all the cages 11a and 11b arrive at the upper and lower parts, they run in opposite directions to go up and down. Both can receive services at the same service intervals.

FIG. 3 shows an example in which three sets (or more than three sets) of the lifting devices of FIG. 1 are installed as one set. This is suitable when there is a large number of upward and downward transportation needs. For example, in the case where there are more upward transportation needs than downward transportation needs, one hoistway 10a goes upwards,
The other hoistway 10b operates alternately downwards, while the other hoistway 10c operates only upwards. That is, the two cages 11a and 11b of the hoistway 10c
Are sequentially operated as an upward movement, and after arriving at the upper portion (including the evacuation area 12), they are forwarded to the lower portion and are again sequentially operated as an upward movement. In this way, it is possible to provide a fair service even if there is a large number of upward and downward needs.

Although the simplest operation method is shown in FIGS. 2 and 3, the actual transportation needs (for example, by the call button signal information on each floor) are incorporated into the control computer, and the operation is performed on the spot. Needless to say, there is a case where the car is analyzed and calculated every moment, and the upward and downward movements of a plurality of cages in each hoistway may be flexibly performed.

FIG. 4 shows an example in which a rope type is used for the lifting mechanism of the lifting device. The upper and lower cages 11a and 11b are suspended by two ropes 15 from the upper ends of both ends thereof. The other ends of these ropes 15 are connected to a counterweight (not shown) via a pulley at the upper part of the hoistway 10,
It is designed to be driven by a motor. Further, the ear portion 16 is projected from the lower cage 11b and the rope 15 is fixed to the ear portion 16 so that the rope 15 of the lower cage 11b does not interfere with the upper cage 11a.

FIG. 5 shows an example in which a linear synchronous motor type is used for the lifting mechanism of the lifting device. A magnetic field generator 18 acting as a mover is attached to each of the upper and lower cages 11a and 11b, and an armature coil group 19 constituting a linear synchronous motor together with the magnetic field generator 18 is vertically installed in the hoistway 10. They are stacked on top of each other and perform a known operation. Of course, since it is a low press, the cages 11a, 11a
There is no interference between b.

[0015]

As described above, according to the lifting device of the present invention, a plurality of cages can be operated by a simple operation in a normal linear hoistway, and space saving can be achieved, so that structural design and layout design of a building frame can be performed. As the degree of freedom in the above is increased, both rope type and low press type can be adopted, so it is highly versatile. Further, according to the operation method of the present invention, it is possible to provide the same service for both going up and going down, and it is possible to sufficiently meet transportation needs.
