Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator-type multi-level parking device including a storage rack and an elevator on which a fork device is mounted.

2. Description of the Related Art An elevator-type multi-level parking device is known in which a plurality of vehicle housing spaces are stacked in a plurality of housing racks and an elevator that vertically transports vehicles via a pallet is combined (JP-A-49-126080). ).

Unlike a gondola-type multi-level parking device, this one vertically transports one car at a time regardless of the number of parked cars, so there is no fear that the required equipment will become extremely large depending on the number of parked cars. There is a great advantage that the system is easy to build.

Problems to be Solved by the Invention According to such a conventional technique, since the vehicle direction changing means is not incorporated in the accommodation rack, the vehicle that has entered in the forward direction must be unloaded in the backward direction.
There has been a problem that the loading and unloading operation of the automobile is complicated and that an unfamiliar driver is likely to have a contact accident. Also,
Even if a turntable for changing direction is installed in front of the doorway, extra land is required to install the turntable, which reduces the utilization of the land and increases the number of vehicles between the storage rack and the turntable. There is no change in being forced to drive backwards.

SUMMARY OF THE INVENTION Therefore, in view of the circumstances of the prior art, an object of the present invention is to provide a swivel device with a lifter on the ground floor of a storage rack, so that the driving operation of an automobile required for loading and unloading can be significantly improved. An object of the present invention is to provide an elevator-type multi-level parking device that can be simplified and improved in safety.

Configuration of the Invention The configuration of the present invention for achieving the above object is a storage rack configured by stacking a plurality of vehicle storage spaces in a multi-tiered manner, an elevator that is built into the storage rack and vertically transports a vehicle through a pallet, and a storage rack. On the ground floor of the, equipped with a turning device disposed in the pit immediately below the elevator, the elevator is equipped with a fork device that can be expanded and contracted toward the vehicle accommodation space, and a platform that is attached to the fork device, while The swivel device includes a pantograph-type lifter and a swivel base mounted on the lifter, and when the elevator descends into the pit, horizontally swings a pallet to be loaded on the elevator through a fork device, so that the elevator is parallel to the elevator. A loading / unloading position that is orthogonal to the transport position and both ends are in contact with the floor surface on both sides of the pit. The main idea is to change the direction of the pallet between and.

Operation With the structure of the invention, the turning device turns the pallet loaded on the elevator horizontally through the fork device, thereby turning the vehicle loaded on the pallet between the transport position and the loading / unloading position. Therefore, it is possible to store the vehicle in the forward direction and leave the vehicle in the same direction.

Since both ends of the pallet are in contact with the floor surfaces on both sides of the pit at the loading / unloading position, there is no possibility of inadvertently leaning when the vehicle enters the pallet and exits from the pallet. In addition, the platform can be used as a safe scaffold when the driver gets on and off the car on the elevator.

An empty pallet 14 can be placed in the home position 15 by extending inward and lowering the elevator 20 to the bottom.

Subsequently, when carrying the automobile C, the above procedure may be repeated. Eventually all car accommodation space 1
If car C is housed in 1, 11, ..., there is no more empty pallet 14 to put in home position 15,
The elevator 20 at that time may stand by at any height.

When the vehicle C housed in the multi-level parking device is unloaded, if there is a pallet 14 at the home position 15, first, it is returned to the original vehicle housing space 11. The procedure for returning the pallet 14 at this time is exactly the same as the procedure for carrying in the automobile C. Further, the car C can be carried out by the same procedure as when the empty pallet 14 is carried to the home position 15, and the car C housed in the car housing space 11 is carried together with the pallet 14 to the home position 15. After that, the vehicle C may be driven in the backward direction to exit from the entrance E of the multilevel parking system.

When subsequently carrying out another car C, it is sufficient to repeat the above procedure, and when carrying in another car C, the pallet 14 at the home position 15 is used as it is, in the order of carrying and carrying. You can follow.

Since the turntable 18 is provided in front of the entrance E of the multi-level parking device, the car C after exiting can change its direction by stopping on the turntable 18.
