The invention discloses a lifting transverse moving type three-dimensional parking garage. The lifting transverse moving type three-dimensional parking garage comprises a vehicle frame and supportingplates, wherein two rows of parking spaces are arranged in the middle of the vehicle frame in the vertical direction, each row of parking spaces comprises a plurality of bottom plates, the corresponding supporting plate is arranged above each bottom plate, and when each lifting table moves upwards, the top face of each locking rod is in contact with a corresponding rectangular frame. Due to the existence of inclined protection plates, each baffle moves towards the interior of a corresponding fixed box, a corresponding first spring is compressed, and the corresponding rectangular frame is inserted between a corresponding stop block and the corresponding fixed box; when each locking rod moves to the middle position of the corresponding rectangular frame, the corresponding locking rod moves to the middle of the corresponding rectangular frame due to the elastic force of the corresponding first spring; besides, the bottom surface of each locking rod is parallel to the inner wall of the corresponding rectangular frame, movement of the corresponding lifting table is limited, positioning work of the lifting tables and the bottom plates is achieved, a sensor is not needed for achieving positioning, cost is saved, and the problem that the sensor is prone to signal faults is avoided; and besides, mechanical positioning is adopted, so that the service life is prolonged, positioning is more accurate, and use is convenient.
