Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an entrance and exit for a vehicle to enter and exit, and an external communication section communicating with the entrance and exit.
A plurality of storage shelves for accommodating vehicle-mounted pallets arranged in the vertical direction, a lifting platform that can be raised and lowered along a vertical traveling path extending between the plurality of storage shelves and the external communication portion, and this lifting platform And a transfer device provided on the elevating table for transferring the pallets between the storage shelves and the storage shelves.

[0002]

2. Description of the Related Art Generally, in such a multi-storey parking lot, the elevating table is suspended by a plurality of cords such as wires and chains, and the elevator is lifted by winding or unwinding the cords. Is configured. Then, the elevating table is positioned at a predetermined storage shelf portion by winding or unwinding the cord-like body, and by the transfer device provided on the elevating table,
The pallet is transferred between the elevator and the storage rack, but in the past, the pallet was transferred by holding the elevator at a predetermined position only by suspending the cord.

[0003]

However, in a cord-like body such as a wire or a chain, expansion and contraction due to temperature change and elongation due to aging occur, so that it is possible to reliably hold the lifting platform at a predetermined position. It was difficult. Even if a sensor for detecting the vertical position of the elevator is provided and the vertical position of the elevator is corrected based on the detection result of this sensor, when the pallet is transferred by the transfer device, When a vehicle is mounted on this pallet, an eccentric load acts on the lifting platform due to the weight of the vehicle, and there is a difference in extension between the multiple cords, and there is a tendency for the lifting platform to tilt. However, it is difficult to maintain the lift table horizontally at a predetermined position, and in an extreme case, there is a possibility that transfer of the pallet may be hindered.

The present invention focuses on such conventional drawbacks, and the purpose thereof is to be able to securely hold the lifting platform at a predetermined position with a relatively simple structure, and to transfer the pallet by the transfer device. The purpose is to provide a multi-storey parking lot that can be placed without any problems.

[0005]

In order to achieve this object, according to the invention described in claim 1, a mounting member which can be mounted on the upper surface of the storage rack is provided on the lift table, and the mounting member is installed. It is configured such that it can be switched between a projecting posture that can be placed on a storage shelf and a storing posture that is stored on the lift table side, and in that projecting posture, the mounting member can be held on the lift table. Therefore, by placing this mounting member on the upper surface of the desired storage rack, by applying a part or all of the total load of the lifting platform including the vehicle to the storage rack via this mounting member, It is possible to securely hold the lifting platform at a predetermined vertical position. As a result, the lift table can be held at a predetermined position regardless of the elongation of the cords such as wires and chains, and also the tilt of the lift table can be prevented when the pallet is transferred by the transfer device. Transfer of pallets can be performed smoothly.

According to the second aspect of the invention, a plurality of storage shelves are arranged on both sides of the elevator path of the elevator table, and
When the mounting members are provided on both sides of the lifting table and the mounting members are switched to the projecting posture, these mounting members can be mounted on the upper surfaces of the storage shelves arranged on both sides of the lifting path. Therefore, when the pallet is transferred by the transfer device, the lift table can be held at a predetermined position more reliably.

According to the third aspect of the invention, the mounting members are provided at the four corners of the elevating table, and all the mounting members are switched in association with the projecting posture and the storing posture in which they can be mounted on the storage rack. As described above, since the mounting members are connected to each other in an interlocking manner, it is possible to more reliably hold the position of the lift table, and it is possible to change the postures of the mounting members at once.

According to the fourth aspect of the present invention, a carriage that can be raised and lowered along the raising and lowering path is provided, and the carriage is moved up and down through a cord-like body, and the raising and lowering table is mounted on the carriage. Since the carriage is configured to be placed and the elevator is raised and lowered by this carriage, after holding the elevator at a predetermined position by the mounting member as described above, the carriage is slightly lowered to remove the entire elevator. The load can be applied to the storage rack via the mounting member, and the lifting table can be reliably held at a predetermined position. At that time, since the cords do not loosen while the carriage is suspended, there is no fear that the cords come into contact with other objects or come off the pulley due to the looseness of the cords.

According to a fifth aspect of the present invention, the transfer device comprises a chain and an engaging member connected to the chain, and the engaging member is engaged with an engaged portion of the pallet. Since the pallet can be transferred between the transfer device and the storage rack by driving the chain, for example, a so-called fork type of transferring the pallet by an extendable fork is used. Compared to the transfer device, the transfer device itself, the storage rack, etc. can be made compact in the vertical direction. In other words, if it is a fork type, it is necessary to perform an operation of lifting and lowering when transferring the pallet, which increases the vertical height of the transfer device,
Also, since a fork is inserted under the pallet, a space is required under the pallet, but this is not necessary in the case of a chain drive, and compared to the fork type, the transfer device and storage rack can be moved up and down. It can be made compact in the direction.

According to the invention described in claim 6, since the mounting surface of the mounting member can be mounted on the upper surface of the bracket provided on the storage shelf side, the bracket is mounted on the mounting member. Can be designed in any shape and size suitable for placement on the board, have the required strength, and can be freely designed.
The brat can be arranged at a desired position by utilizing the extra space, which is extremely convenient in actual practice.
