Self-advancing transition device of gangue filling machine

A self-advancing transition device of gangue filling machine comprises height adjusting oil cylinders 1, traction oil cylinders 2, a guide rail 3 and pulleys 4, a transition frame, a carrying roller, a control valve and the like. The bottom ends of the height adjusting oil cylinders 1 which are vertically arranged on two sides of the transition frame are movably connected with a movable support 9 which is provided with the pulleys 4 on the bottom. The traction oil cylinders 2 on two sides of the transition frame are hinged between the transition frame and a cradle 14 of the guide rail 3. Paired pulleys 4 are inserted on two sides of the I-shaped steel guide rail 3. When a gangue filling machine needs moving backwards, the device utilizes the power of a hydraulic system of the gangue filling machine to enable the transition frame to lift and fall through the height adjusting oil cylinders 1, the transition frame is moved backwards through the traction oil cylinders 2, and the integral self-advancing can be rea
