The invention discloses a changeable track and belongs to the field of conveying devices. The changeable track comprises a driving device, a connecting frame, a control unit and a track body. The track body comprises a rotary track body and a fixed track body, and the fixed track body and the driving device are disposed on the connecting frame. The control unit is connected with the driving deviceso as to control the driving device to run. The driving device is connected with the rotary track body, so that the rotary track body is driven to rotate along the plane where the fixed track body islocated till the rotary track body is connected with the fixed track body. The connecting frame is disposed in the connecting position of the track body. Direction switching is performed through therotary track body on the connecting frame, thus a universal cloud deck can rotate on the track body in a large angle range, the problem that a traditional circular-arc transition track is prone to being limited by the space is solved, the changeable track can be used for simultaneous running of a plurality of universal cloud decks, and the flexibility and the utilization ratio of the traditional track are improved.
