DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator type multi-story parking device, and more particularly to a multi-story parking device for transferring vehicles between an elevator device and each parking space.

[0002]

2. Description of the Related Art In elevator type multi-story parking devices,
The carriage of the elevator device is equipped with a traveling rail and a feed mechanism, and a fixed traveling rail is provided in the parking space on each floor, and the vehicle is parked with the pallet together with the pallet via the traveling rail connected by vertical movement of the carriage and the fixed traveling rail. 2. Description of the Related Art Vehicle transfer devices that can be transferred to and from a space are known.

[0003] The feed mechanism of this type is a combination of a slide frame that moves back and forth in parallel with the travel rail and a feed chain that moves the pallet along the travel rail. In addition, a small-diameter roller is incorporated in the pallet to move and move along both the traveling rail and the fixed traveling rail.

Therefore, in this device, the feed chain is advanced to the parking space side via the slide frame, so that the engagement pieces of the feed chain can be engaged with the engagement blocks of the pallet, and the feed chain is turned forward and backward. By driving, the pallet in the parking space can be pulled out onto the carriage, the pallet on the carriage can be stored in the parking space, and the vehicle can be transferred via the pallet.

[0005]

According to the conventional technique, the slide frame does not enter the entire length of the lower portion of the pallet, and the engaging piece of the feed chain is moved relative to the engaging block of the pallet. However, since the pallet was engaged only from the rear side in the moving direction of the pallet, the pallet had to be stopped at a fixed position by a stopper, and a large impact was generated at the time of positioning. Need to be kept low,
There was a problem that it was difficult to speed up the entry and exit operations.

Accordingly, an object of the present invention is to prevent the pallet from coasting by engaging the engaging pieces of the feed chain with the engaging blocks of the pallet from both front and rear sides.
It is an object of the present invention to provide a vehicle transfer device of a multi-story parking device that can further speed up and exit operations of a vehicle.

[0007]

In order to achieve the above object, the present invention comprises a pair of left and right supporting frames, a connecting frame before and after connecting the supporting frames in a frame shape below the carriage, and a supporting frame. And a feed chain that runs along the upper edge of the slide frame so as to be able to move back and forth on the connection frame in parallel with the support frame. Penetrating square holes are formed in the front part and the rear part, and the feed chain includes engagement pieces that engage from both front and rear sides with engagement blocks protruding from the lower surface of the pallet, and extend over the entire length of the pallet movement stroke. The gist is that the pallet is restrained and driven.

The slide frame can be moved back and forth with a feed chain via a pinion meshing with a rack on the connecting frame, and the support frame slides via a pinion meshing with a rack on a horizontal frame of the carriage. It can be moved horizontally with the frame.

Further, the feed chain can be driven by a speed reducer motor with a brake.

[0010]

According to the structure of the present invention, when the feed chain is moved forward and backward by the pallet, the engaging pieces which engage with the engaging blocks of the pallet from both front and rear sides extend the entire length of the moving stroke of the pallet. Over this, the pallet can be restrained and driven. Therefore, since the pallet can be accelerated and decelerated arbitrarily, even when moving at high speed, the pallet can be safely positioned and stopped at a fixed position via the feed chain without using a special stopper. be able to. The support frame is connected in a frame shape on the lower side of the carriage via front and rear connection frames, and the horizontal frame of the carriage has square holes formed in the front and rear portions of the support frame and the slide frame. Penetrates. So, the support frame,
The slide frame can share a part of its height with the thickness of the carriage, so that the overall thickness can be greatly reduced as compared to a case where each is simply mounted on the upper surface of the carriage.

The required height can be minimized by moving the slide frame back and forth through a pinion that meshes with a rack on the connecting frame.

The required height can be minimized by moving the support frame laterally via a pinion that meshes with a rack on the horizontal frame of the carriage.
If the support frame is moved laterally together with the slide frame, for example, even if a plurality of parking spaces are arranged side by side on the same floor, it is possible to cope with one common carriage and to provide a feed chain. By previously moving the engaging pieces to appropriate positions, the engaging blocks of the pallet can be inserted between the engaging pieces from the lateral direction of the feed chain, and the former can be engaged with the former.

When the feed chain is driven by a speed reducer motor with a brake, the pallet is positively fixed by the motor brake as long as the engaging piece of the feed chain is engaged with the engaging block from both front and rear sides. For example, high safety can be ensured even during vertical transport by the elevator device.
