Abstract: Aiming at the problems of incomplete space utilization of the existing doublelayer vertical parking device in the old urban area and interference between the parking and taking of the upper and lower twolayer vehicles, a doublelayer vertical parking device with the functions of lifting and moving horizontally was designed, in which the semiground and semirail structure was adopted by the frame and the download plate lateral moving systems, and the chain drive and ropewheel structure was adopted by the upload plate system. The key components of the parking device, such as the loading plate, the frame guide rail seat and the lifting long axis were analyzed by ANSYS Workbench. The stability of the parking device under the wind load was studied. The prototype of the parking device with a reduced ratio of 1∶10 was made and its function was tested. The results indicate that the strength and rigidity of the key components of the parking device and the stability under the wind load can meet the safety requirements. The designed parking device has a compact structure, and can easily realize the noninterference parking and taking of the upper and lower vehicles.
