Three-dimensional track for storage system

The invention relates to the technical field of sorting, and discloses a three-dimensional track for a storage system. The three-dimensional track for the storage system comprises a base, an entrancetrack and a mobile track, wherein the entrance track is used for clamping and positioning a shuttle vehicle; and the mobile track is connected with the entrance track and comprises horizontal tracks,vertical tracks and reversing tracks, the horizontal tracks and the vertical tracks are connected to form intersections, the reversing tracks are installed on the intersections, and the reversing tracks selectively communicate with the horizontal tracks. The shuttle vehicle enters from the entrance track and moves along the horizontal tracks, the reversing tracks are adjusted not to communicate with the horizontal tracks, and thus the shuttle vehicle can enter the vertical tracks from the horizontal tracks. On the contrary, the shuttle vehicle continues moving along the horizontal tracks, because of the reversing track
