Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a lifting lift for parking equipment.

Conventionally, there has been a lift that moves up and down between the parking space formed on the floor or underground and the entrance on the ground to enter and exit vehicles, but in this case, due to the arrangement of pillars of the building, the lift The location of the hoistway may be offset from the location of the entrance.

To avoid this, conventionally the position of the hoistway was shifted to match the position of the entrance, but in this case an unusable space is created between the hoistway and the wall, which is the most important space for parking equipment. Not only does the utilization rate decrease, but also when installing guide devices for lifting lifts, the distance from the wall or pillar increases, making it necessary to strengthen support brackets, etc.
Therefore, equipment costs also increase.

Furthermore, the lifting lift requires some type of locking means to prevent the vehicle-mounted pallet from falling due to movement during lifting and lowering.

In view of the above-mentioned current situation, the present invention has been developed by arranging two rotary levers that can be rotated by an appropriate power source between two rails for supporting a pallet mounted on a vehicle in an elevating lift. The provided roller engages with two groove-shaped guide rails provided on the back of the pallet to lock the pallet, and when the lifting lift reaches the entry position, the loaded pallet is rotated by the rotation of the rotating lever. The purpose of this is to move the loaded pallet horizontally by an appropriate amount onto two rails provided on the floor of the entrance, thereby correcting the deviation of the position of the pallet from the entrance. This relates to a locking and shifting device.

0 or 11), the vertical transfer paths 2 and 2' are arranged so that there is an empty space for one piece each, and the horizontal transfer motors 21 and 21 simultaneously oppose each other, and the vertical transfer motors 29 and 29 simultaneously oppose each other. The transfer is carried out alternately for one pallet, and when a vehicle is carried in or out of pallet 10 or 11, only the lateral transfer motor 21 on the side of lateral transfer path 1' is driven independently, as shown in FIG. It is arranged in a pallet arrangement as possible.

First, when transporting a vehicle, the desired empty pallet 11 is transferred onto the lift 50 as shown in FIG. situation). Next, operate the motor 60 to lift the lift 50.
is raised to the entry compartment 4, and the motor 71 is driven again to move the pallet 11 toward the stepped floor 5 as shown by the two-dot chain line in FIG. Therefore, palette 1
1 supports a traversing wheel 18 with a fork 57 that also serves as a rail and a rail 75, and the vehicle can easily enter the pallet 11 while avoiding contact with the building pillars at the entrance 6.

When the vehicle loading is completed, the pallet 11 is returned onto the lift 50 by the motor 71 in the reverse order.
The lift 50 is lowered by the motor 60 while the rollers 74 and the guide rails 48, 49 are in the engaged state. Therefore, the pallet 11 is held on the lift 50 during elevation and descent by the rollers 74.

The pallet 11 and the adjacent pallet 10 on the vertical transfer path 2 are connected to each other when the lift 50 is raised and lowered because the connecting fittings 12 and 13 on the pallet 11 side are suspended downward from above. does not cause any problem.

Next, the motor 71 is driven again to disengage the roller 74 from the guide rails 48, 49, and the motor 21 on the horizontal transfer path 1' side is rotated in the opposite direction to move the pallet 11 onto the vertical transfer path 2. Pull into.

In this state, the transverse wheel 18 provided on the left side of the pallet 11 is connected to the longitudinal cart 2 located in the left column.
It is supported on short rails 26 of 4' and 24', and then the horizontal transfer motors 21 and 21 can be driven to perform simultaneous opposite horizontal transfer, and the vertical transfer motors 29 and 29 can be driven. It is also possible to drive and perform simultaneous opposing longitudinal transport.

Vehicle removal can be carried out in exactly the same manner as described above.

In the above explanation, the horizontal circulation part of the pallets was assumed to be one layer, but if the lift length is increased and the position of the pallet connecting fittings for each layer is shifted, it can be carried out in exactly the same way as a multi-layer pallet. Furthermore, if the opening direction of the connecting fittings is reversed, a parking space can be provided on the upper floor.

As detailed above, when using the device of the present invention,
During the lifting/lowering operation of the lifting lift, the mounted pallet is restricted from moving in the left/right direction by the engagement of the two guide rails provided on the back of the pallet and the roller at the tip of the rotating lever provided on the lift side. The pallet is completely locked because it is regulated by the engagement between the flanged wheels installed on the pallet side and the rails installed on the lift side, and the entry point on the ground is out of alignment with the hoistway. Also, by moving the pallet laterally by rotating the rotary lever, the center of the pallet can be easily aligned with the center of the entrance, thereby allowing vehicles to enter and exit safely. Therefore, the hoistway can be placed close to the wall surface that is offset from the entrance, which not only makes the use of space extremely effective, but also makes it easier to install the guide device for the lift because the guide rails etc. are close to the side walls and pillars. The mounting brackets are short and easy to install.

Furthermore, the groove-shaped guide rail on the back side of the pallet used in the above-mentioned locking and shifting device is not specially provided, but is used to move the pallet horizontally by engaging with auxiliary guide rollers provided on the floor during vertical transportation in a parking space. Since it can also be used as a guide to prevent positional deviation in the direction, the structure is simple and inexpensive.
