Description

[Detailed explanation of the invention] [Industrial application field] This invention relates to a pallet-type multi-story parking lot that uses pallets to store cars together with the pallets.
More specifically, the present invention relates to a pallet-type multi-story parking lot that eliminates the needless transportation of empty pallets and enables quick entry and exit of automobiles.

[Conventional technology]

2. Description of the Related Art Mechanical multi-level parking lots are known in which when a driver drives a car to an entrance within the main body of the garage, the car is automatically stored in a parking shelf within the main body of the garage. The special parking device certification standards certify nine types of mechanical multi-storey parking lots with automatic storage methods.
Among these, the elevator slide method employs the dolly method, comb method, puzzle tower method, and pallet method as methods for storing cars from the elevator into the parking rack.

However, with the dolly type, there are practical problems with the method of lifting and towing one of the front or rear wheels of the car with a trolley due to the increase in the number of front-wheel drive cars. The puzzle tower type has problems such as the shelving cost being relatively high and the rainwater on the cars staining the cars on the lower shelf during rainy days. There are also problems such as higher costs, and because pallets with wheels travel from each shelf, there are many moving parts, increasing the probability of failure.

[Problem that the invention attempts to solve]

On the other hand, the pallet type does not have the above problem because the automobile placed on the pallet is transferred by a transfer device from the elevator to the parking shelf and stored.

However, in the pallet type, the car is stored in its entirety on a parking shelf, so when the car is parked, the empty pallet has to be carried from the shelf to the entrance inside the garage body and taken out. When leaving the garage, the car must be taken out at the entrance of the garage itself and the empty pallet must be transported to an empty shelf and returned.

For this reason, it takes time to enter and exit a car, and the biggest drawback is the access time, which is considered most important in mechanical multi-level parking lots. especially,
In mechanical multi-level parking lots, vehicles enter the parking lot continuously during the parking period, and vehicles exit the parking lot continuously during the exit period, which poses a major problem.

In view of the above-mentioned current situation, the purpose of this invention was to transport empty pallets from the parking shelf to the entrance and vice versa when entering and exiting the garage by storing and taking out each pallet to and from the parking shelf inside the garage. Eliminates the need to transport empty pallets from the parking lot to the parking shelf.
To provide a pallet type multi-level parking lot in which cars can be quickly entered and exited.
