Anti-derailing sliding rail device

The utility model discloses an anti-derailment slide rail device, which relates to the technical field of ore transportation, and comprises a slide rail base and a branch slide rail, the inside of the slide rail base is fixedly connected with a rail, the branch slide rail is in sliding connection with the outer wall of the rail, the outer wall of a threaded block is in threaded connection with an ore transfer car, and the threaded block is in threaded connection with the ore transfer car. Damping assemblies used for damping are arranged in the branch sliding rails, and damping springs are connected to the outer walls of the storage grooves. According to the anti-derailment sliding rail device, the sub sliding rails move to drive the mine car to move, the connecting stability between the sliding rail base and the mine car can be improved through the multiple sets of rails and the sub sliding rails, the sub sliding rails are prevented from derailing when the outer walls of the sub sliding rails are blocked by t
