BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a revolving type multi-level parking system which accommodates and parks a large number of automobiles in a small site.

[0002]

2. Description of the Related Art Conventionally, as a parking apparatus of this type, an arm for holding a plurality of cages for mounting on a vehicle is radially arranged on a rotating body having a guide frame or a circulation guide rail for defining a circulation path of a cage. Then, a cage which is hung in a swinging cage shape on the arm via a support shaft is circulated and rotated along a guide frame or a circulation guide rail (for example, Japanese Utility Model Laid-Open No. 1-142758, Japanese Patent Laid-Open No. 3-137364), A pair of rails that form an annular movement path along the vertical surface are provided with movable chains, and a mounting member for rocking the cage is attached to this chain, and the sprocket meshed with the chain is rotated by the drive means. (For example, Japanese Patent Laid-Open No. 2-147774), and in a circulating chain structure, a push link plate,
Pin link plates are arranged alternately and these are connected via cotter pins.
No. 6 publication) and the like.

[0003]

However, in such a conventional rotating body in which the arms are radially arranged, the member stress of each arm member acts in the bending direction, and the flexural strain stress acts on the arm member at the center of rotation. Therefore, the arm member itself may be cracked, broken, or the like, or the reverse torque due to the cage loading load may act on the rotation driving means itself to cause drive damage or the like. There was such a problem. In addition, since a chain is provided on each of the pair of rails so as to be movable, and the rotation drive and the load support are performed by this chain, there is a drawback that both the drive ability and the support ability for the cage-loaded load are not compensated for and deteriorate. Had. Then, in order to eliminate this drawback, it has been proposed to provide a separate chain mechanism in which the rotation drive and the load support are independent of each other, but by increasing the number of parts constituting the device and the manufacturing process, There is a problem that it becomes complicated and costly. Furthermore, most of the conventional cages are formed in the shape of a swing cage, so the cage itself will sway from side to side due to its load during cyclic movement with the vehicle installed, so that the circulation speed does not become too fast. If it is not controlled at all times, there is a risk of the vehicle falling due to the vibration. In addition, there is a problem in that cages are agitated by external vibrations of a typhoon or an earthquake, and adjacent cages in a suspended state collide with each other or the vehicle falls.

Therefore, the present invention has been made in view of the above existing circumstances, and it is possible to mount a plurality of vehicles on which a drive capacity and a support capacity for a cage loading load are not reduced as much as possible. Allows the cage to circulate smoothly from a predetermined vehicle collection / removal position in the vertical direction, and eliminates the various risks associated with cage swings to efficiently park and accommodate a large number of cars in a small site.
