Description

Description: TECHNICAL FIELD The present invention relates to a hatch structure of a circulation type elevator that operates by circulating a plurality of elevator cars in a vertical direction.

[Conventional technology]

An example of a circulation type elevator that performs efficient operation by sequentially circulating a plurality of elevator cars in the vertical direction is the one proposed in Japanese Patent Laid-Open No. 62-111886.

FIG. 2 is a front view showing the entire structure of this circulation type elevator. In the figure, reference numeral 10 indicates a surrounding section so as to form a parallel section via wheels 11 axially installed on the upper and lower vehicle bodies of the building, respectively. An endless wire belt installed. This endless wire belt 10
Is driven to travel in one direction (arrow X) by the electric conduction motor 12 via the drive transmission mechanism 13. Further, 14 and 15 are fixed rails installed along both parallel portions of the endless wire belt 10, and movable rails for moving the connecting positions by moving between the both ends of the fixed rails 14 and 15 in parallel. 16 are slidably mounted on a guide shaft 17 respectively, and a transfer track of a hydraulic cylinder 18 constitutes a track for moving and connecting the movable rail 16 to the ends of both fixed rails 14 and 15. .
A traveling mechanism 20 in which an elevator car 19 is fixedly installed on one side is installed on a track formed by the fixed rails 14 and 15 and the upper and lower movable rails 16.
Is supported by fixed rails 14 and 15 or movable rail 16 so that it can travel freely, and either one of chuck mechanisms 21 and 22 fixed to both sides of elevator car 19 holds endless wire belt 10 therebetween. . In addition, the traveling mechanism 20 is provided with a braking fixing mechanism 23 which is interlocked with the chuck mechanisms 21 and 22 and which travels and fixes between the rails 14, 15 and 16 when the chuck mechanisms 21 and 22 are used. And stop at an appropriate position 24 on the track. Then, the elevator is centrally controlled by the central control unit, and the elevator car 19 controlled to keep a constant interval moves by repeatedly releasing the connection with the endless wire belt 10 by the chuck mechanisms 21 and 22. At one end, the hydraulic cylinder is supported by one fixed rail 14 or 15 while being carried on the movable rail 16.
A chuck mechanism 21, 22 that drives 18 to move to the other fixed rail 15 or 14 and at the same time clamps the endless wire belt 10.
By changing, the movement direction is changed to the opposite direction.

With such a device, it is possible to install multiple elevator cars in a limited hoistway area, and it is possible to significantly improve the economic efficiency. However, an elevator using an endless wire belt via a detachment mechanism is used. Since it is driven, the operating speed of the elevator car cannot be increased so much, and it is difficult to employ it in a skyscraper, for example, which exceeds several hundred meters.

For this reason, recently, a circulating elevator using a linear motor as shown in FIG. 3 has been proposed. That is, the primary coil 33 of the linear motor is arranged along the dedicated road wall on the dedicated path 31 for rising and the dedicated path 32 for lowering, and the secondary conductor 34 of the linear motor is provided on the elevator cars A to I.

The elevator cars A to I are designed to traverse by themselves in the upper part. And at the top, the hoist 36
After suspending the elevator cars A to H once, each dedicated road 31,3
The support base 37 is sent to 2 and the elevator car is placed on the support base 37 so that the elevator car can be moved laterally. At the bottom, the hydraulic jacks 38 provided in the pits support the elevator cars A to I. It is configured so that it can be traversed by
In addition, a waiting space for a car is provided at the bottom.

[Problems to be Solved by the Invention]

However, with the above configuration, it is possible to make multiple cars stand by by extending the waiting space of the car, but when using the waiting car for driving again, It is necessary to move in order, and it is not possible to select and use any car. Therefore, for example, when a car stored in the standby space later is a defective car, there is a problem that all the cars stored before that become unusable.

The present invention has been made in view of the above points, and it is possible to put a plurality of cars on standby, and from among them, according to the traffic demand or the traffic situation, an arbitrary car does not interfere with other cars and is free.
