Technical Field

[0001] The invention belongs to the technical field of rail transportation equipment, and particularly relates to a rail unloading, turning and shifting device. Background Art

[0002] In the maintenance of railway line rails, after a new rail is transported to a corresponding position by a carrier vehicle, the new rail is then unloaded onto the line. In the prior art, rail unloading is mainly achieved in the following way: a special vehicle with a rail unloading channel is arranged at the tail of the carrier vehicle, and the rail is unloaded inside or outside the line by controlling the special vehicle. For example, the rail receiving and unloading operation arm and the rail transport vehicle disclosed in Chinese Patent CN112832073A can unload the rail, but it needs to be customized separately, and at the same time, a complex control system needs to be equipped, resulting in high overall manufacturing and operation and maintenance costs and poor versatility. Summary of the Invention

[0004] For this reason, the technical solution adopted by the invention is as follows: a rail unloading, turning and shifting device includes a rail shifting frame arranged on a mounting seat at the tail of a carrier vehicle. A support assembly capable of sliding left and right on the rail shifting frame and for the rail to move is arranged on the rail shifting frame. An anti-tipping assembly for preventing the rail from tipping over is arranged on the support assembly. A moving cylinder for realizing the left and right movement of the support assembly is arranged at the bottom of the rail shifting frame and extends left and right. The fixed end of the moving cylinder is arranged on the mounting seat at the tail of the carrier vehicle through a fixing component. A limiting chute extending left and right is arranged on the rail shifting frame. The moving end of the moving cylinder is arranged on a connecting block, and the connecting block is arranged on the support assembly after passing through the limiting chute.
