The invention provides a spherical wheel two-way moving parking space mechanism, which includes a transport trolley, longitudinal guide rails, transverse guide rails, parking frames and lifting mechanisms. The transport trolley includes a trolley plate, spherical wheels, an axle control system and a driving system, the spherical wheels and the axle control system are all arranged on the bottom side of the trolley plate, the driving system controls rotation of the spherical wheels through the axle control system, and concave comb teeth are arranged on the opposite side edges of the trolley plate; the one or more pairs of parallel longitudinal guide rails and the one or more pairs of parallel transverse guide rails are arranged perpendicular to each other, and the trolley plate moves along the longitudinal guide rails and the transverse guide rails through the spherical wheels; the parking frames are of a square frame structure, the sides, provided with openings, of the parking frames are inlet ends, the parking frames are orderly arranged on the outer sides of the transverse guide rails in pairs in the length direction of the transverse guide rails, and the inlet ends directly facethe transverse guide rails; the size of the trolley plate is matched with the sizes of inner frames of the parking frames, and convex comb teeth interlaced with the concave comb teeth are arranged onthe inner sides of the parking frames; and the parking frames are provided with at least three lifting mechanisms.
