Double-layer parking device based on ground access platform

The utility model relates to a double-layer parking device based on the ground as an in-out platform. The utility model belongs to the technical field of automobile mechanical engineering, and relatesto a double-layer parking lot, which takes an underground volume hollowed out in the open air as an underground parking space of the double-layer parking lot, a lifting power system is formed by stand columns and a driving motor, a lifting device is formed by two layers of vehicle carrying plates and a vehicle carrying plate support frame, and the lifting device lifts along the stand columns under the driving of the driving motor. The three-dimensional parking garage is very compact in structure, simple in mechanical principle among composition structures of all parts, easy to construct and low in manufacturing cost, and can solve the problems that parking is difficult and cars in some small parking lots are inconvenient to get in and out at present. The three-dimensional parking lot is suitable for being applied
