At present, the rail change of the railway still relies on manual operation. The obvious shortage is that manual rail change is a heavy manual labor and requires a lot of people, but it takes a long time, is low in efficiency, and has poor safety.A railway track changer includes a cross beam and a movable lifting device. It is mounted on two supports through a guide sleeve and a flange. The upper part of the support is provided with lifting holes, the guide sleeve is provided with positioning holes, and the guide sleeve is inserted through a pin. It is fixed on the lifting hole of the bracket, the bottom of the guide sleeve is fixed with the flange, and the beam is clamped and fixed by the flange.
