Supporting structure of carrier running rail for parking garage

The utility model relates to a supporting structure of a carrier running rail for a parking garage. The structure comprises a guide rail, a transversely-moving tray, a tray rail, a transversely-moving device, a running rail, connecting parts and a plurality of beams. The tray rail is fixed to the transversely-moving device. The transversely-moving tray is installed on a frame of the tray rail. The transversely-moving device and the running rail are fixed to the guide rail. The beams are fixed to the lower portion of the transversely-moving device through the connecting parts and fixed to the running rail at intervals. By means of the design, the transversely-moving tray can transversely move even though not in adjacent connection with a carrier and moves loads to an elevator before the carrier reaches, the time can be saved, and the supporting effect on the running rail is achieved; due to the fact that a running path is arranged on the upper layer of a road, the carrier can run safely, and the effect that vehicles can more easily enter and exit from the parking garage from the running-in station is achieved. Due to the structural design of the beams and the connecting parts, the length of the beams is reduced, and the rigid supporting effect of the beams is improved.
