Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a multi-story parking system in the form of a multi-story safe, comprising a storage rack and an elevator equipped with a fork device.

Conventional Technology In cities, it is extremely difficult to secure parking lots in terms of both price and area, and the need for effective use of land is increasing.As a countermeasure, various types of multi-level parking systems are being developed. It has been developed and put into practical use.

In particular, many gondola-type multilevel parking systems are being constructed as a type suitable for extremely narrow parking lots. A gondola-type multilevel parking system has two sets of sprockets at the top and bottom, and two sets of conveyor chains are stretched between each sprocket at the top and bottom. It consists of a large number of so-called gondolas that carry cars, and the gondolas are circulated by rotating the sprocket at the top. When entering and exiting the warehouse, other gondolas are hoisted high upwards with cars loaded on them by conveyor chains.

Problems to be Solved by the Invention However, in such a device, since the total weight of the entire gondola and the total weight of the cars loaded on it is loaded on the conveyor chain, the chain tension acting on the conveyor chain is There was a problem that the number of cars was too large and it was difficult to accommodate a large number of cars. Furthermore, when circulating in the gondola, there are cases where cars are unevenly distributed only on the descending side or only on the descending side, so there is a problem that the output of the drive motor needs to be large.

Therefore, in view of the actual state of the prior art, an object of the present invention is to allow the elevator to enter and exit the multi-tiered vehicle storage space one by one, thereby reducing the load acting on the elevator. Since the weight is always the same as one car, the load does not limit the number of cars accommodated, and the required output of the elevator drive motor becomes extremely large as the number of cars accommodated increases. Our objective is to provide a new multi-level parking system.

Means for Solving the Problems The present invention has a fork device for loading a pallet for loading automobiles onto the center of a storage rack in which a plurality of car storage spaces are stacked in multiple stages. A storage shelf for supporting the pallets 1 to 1 is provided in each car storage space, and when the fork device extends into the car storage space and moves up and down, the fork device and the storage shelf are connected to each other. The fork device transfers the pallet loaded with cars between the car storage space and the elevator without interference, and the elevator transports the pallet between the car storage space and the home position. The gist is what we did.

Therefore, when using this configuration, first, with the pallet on the fork device, the elevator is opened to the home position, a car is placed on the pallet, and then the elevator is driven to load the car. By transporting the pallet to any car storage space and then placing the pallet on the storage shelf of that car storage space using a lifting device, the car can be stored in the car storage space. By completely reversing the procedure, the car stored in the car storage space can be transferred from the car storage space onto the elevator, transported to the home position, and then started and taken out. It is possible.

Example Examples will be described below with reference to the drawings.
