[Background Art and Problems to be Solved by the Invention]
In a multi-level parking facility that can circulate a plurality of cages, each equipped with a pallet for detaching a vehicle, the vehicle entering the vehicle advances on the pallet of one cage that reaches the entry / exit floor. . A multi-story parking facility equipped with a turning device that turns the pallet 180 degrees in a horizontal plane is also known so that the vehicle can be moved forward when leaving the vehicle. The plurality of cages are attached to an endless chain. By rotating the endless chain via a sprocket by an electric motor, the entire cage is circulated up and down. An example of such a parking facility is disclosed in JP-A-6-307112.
[0003]
In this multi-story parking facility, a pit is formed on the ground, and a turning device is disposed in the pit, and a plurality of cages provided with pallets are circulated up and down. Then, when the vehicle advances and enters the pallet that reaches the pit on the entry / exit floor, the turning frame of the turning device ascends from inside the pit below the pallet, and pushes the pallet from below to release it from the cage. Thereafter, the swivel frame is swung 180 degrees in the horizontal plane with the pallet placed, and then lowered to place the pallet on the cage again. Thus, in order to pivot the pallet, it is necessary to lift it and disconnect it from the cage. Therefore, a plurality of jacks are provided in such a turning device for raising and lowering the pallet before and after the turning. This jack raises and lowers an object by a rotating / straightening mechanism such as a built-in ball screw.
[0004]
On the other hand, recent vehicles tend to increase in weight with each model change in order to improve power performance, expand vehicle interior space, and improve vehicle body strength. Therefore, the number of vehicles that cannot be parked for the reason that the allowable weight of the turning device in the existing multi-story parking facility is increased. In particular, the main reason is that the vehicle weight exceeds the lifting ability of the turning device. In order to solve this problem, it is necessary to change the rotation / straight-forward mechanism of the jack and to change the electric motor and transmission mechanism for driving the rotation / straight-forward mechanism. Therefore, the modification cost is very high. Furthermore, there is a possibility that the size of the entire swivel device needs to be changed along with the change to a large capacity lifting tool. If so, the cost of remodeling will increase further.
[0005]
The present invention has been made in order to solve such a problem, and is provided with a lifting assist device for a swing device in a multi-story parking facility that can be attached to and detached from an existing swing device and can add a pallet lifting force with a simple structure.
