The invention discloses a circular stereo garage with double car carrying plates capable of being exchanged simultaneously, and solves the problem of low car
storage efficiency. The circular stereo garage comprises a multi-layer frame with a cylindrical structure, an exchange device, a carrying device and a
parking space device, wherein the multi-layer frame comprises an exchange layer, a plurality of vehicle storage
layers and a roadway, the exchange device comprises a vehicle carrying plate, a lifting mechanism, an upper-layer exchange mechanism and a lower-layer exchange mechanism, the carrying device comprises a vehicle carrying plate, an
elevator, a rotating mechanism, a
lap joint mechanism, an upper-layer carrying mechanism and a lower-layer carrying mechanism, the
parking space device comprises a vehicle carrying plate, an upper-layer conveying mechanism and a lower-layer conveying mechanism, the upper-layer exchange mechanism exchanges the vehicle carrying plates with the upper-layer carrying mechanism, meanwhile, the lower-layer carrying mechanism and the lower-layer exchange mechanism exchange the vehicle carrying plates, the upper-layer carrying mechanism and the upper-layer conveying mechanism exchange vehicle carrying plates, meanwhile, the lower-layer conveying mechanism and the lower-layer carrying mechanism exchange the vehicle carrying plates, and the
lap joint mechanism is used for transmitting the vehicle carrying plate driving force of the carrying device to the exchange device or the
parking space device.
