BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting device for a multi-story parking facility.

[0002]

2. Description of the Related Art As an example of a multi-story parking facility, Japanese Patent Laid-Open No.
There is an elevator type as described in Japanese Patent No. 85472. This is provided with a lifting platform that supports and lifts a pallet on which a vehicle is mounted, and a plurality of parking shelves for accommodating the vehicle together with the pallet are arranged on both sides of the lifting platform along the hoistway. In this device, the lowermost portion of the hoistway is an entrance where a vehicle enters for parking, and the elevator is moved up and down between the entrance and the parking unit where the parking shelf is provided. Has become.

The elevator is generally formed in a rectangular shape, and is suspended from above the elevator by wire ropes connected to four corners thereof. In this case, each wire rope is wound around a winding drum of a hoist via a sheave provided above the hoistway, and a wire rope extending from the winding drum is provided on the side of the hoistway via the sheave. It is usually connected to a balance weight.

[0004]

However, in the elevating device as described above, when one of the wire ropes connected to the four corners of the elevating platform is cut, the elevating platform is inclined.
Therefore, even in such a case, it is necessary to take safety measures separately so that the vehicle on the lifting platform does not fall, but it is difficult to prevent the vehicle from falling from the inclined lifting platform, and a means for that is provided. As a result, the structure of the lift platform is complicated and the weight is increased.

[0005]

SUMMARY OF THE INVENTION In order to solve such a problem, the present invention reduces the number of wire ropes connected to each part of a lift table to two, and one of them is used as a winding drum of a hoist. By winding and connecting the other one to the balance weight, even if one of the two wire ropes connected to each part of the elevator may be cut, the elevator is inclined. It is something that does not happen.

[0006] That is, a first means for solving the above-mentioned problem (the invention according to claim 1) comprises a loading portion into which a vehicle is loaded for parking and a vehicle provided above or below the loading portion. What is claimed is: 1. A lift device of a multi-story parking facility for raising and lowering a vehicle with respect to a stored parking unit, comprising: a lift platform on which the vehicle is mounted; and a plurality of first wires respectively connected to a plurality of locations around the lift platform. A rope, a plurality of second wire ropes respectively connected to a plurality of locations around the lift platform in proximity to a connection point of the first wire rope, and a plurality of second wire ropes arranged above the lift path of the lift platform; A winding drum of a hoist around which each of a plurality of first wire ropes is wound via a sheave; and a side of the hoistway, wherein each of the plurality of second wire ropes is connected via a sheave. Balance weight The features.

A second invention for solving the above-mentioned problem is obtained by developing the above-mentioned first means, wherein the plurality of second wire ropes are grouped into one or more sets, and The two-wire rope is connected to one balance weight.

[0008]

In each of the above means, of the first wire rope and the second wire rope connected to each part of the elevator,
Even if the first wire rope wound around the winding drum is cut, since the load of the balance wit is acting on the second wire rope, the connecting position of the cut first wire rope on the elevator is lowered. Nothing. In addition, even when the second wire rope is cut, only the load on the hoist increases, and the tilt of the elevator does not occur.

When both the first and second wire ropes are wound around the winding drum, an excessive load acts on one short wire rope due to the difference in elongation of the two wire ropes, and the other wire rope is overloaded. It is not preferable because a load is not applied to the rope.

Further, in the second means, several second
Since the wire ropes are bundled and connected to one balance weight, even if one first wire rope is cut, the corresponding second wire rope can receive all of the weight of the heavy balance weight. And the inclination of the elevator can be prevented more reliably.

[0011]

Therefore, according to the above-mentioned means, two wire ropes are connected to each wire rope connecting point of the elevator, one of which is wound around the winding drum of the hoist, and the other is connected to the balance weight. Because of the connection, even if one wire rope is cut, the elevator is prevented from tilting.

Further, according to the second means, several second wire ropes are put together and connected to one balance weight having a large weight, so that the lifting platform when one wire rope is cut is provided. Is more reliably prevented.
