The invention discloses excavator crawler belt replacing equipment. The excavator crawler belt replacing equipment comprises a machine body; a lifting block capable of sliding front and back is arranged in the bottom wall of the machine body; a plurality of lifting lead screw cavities are formed in the lifting block; a lifting gear cavity is formed in the rear wall of the lifting block; and a lifting device is arranged in the lifting gear cavity, wherein the lifting device moves away to realize lifting of an excavator through cooperation of a worm gear and a lead screw nut and through self-locking of the lead screw nut. According to the excavator crawler belt replacing equipment, the lead screw nut is driven through the worm gear to be self-locked in a matched mode to lift the excavator toreplace a crawler belt; a gear is pushed by a conical block to change the diameter, so that the gear can mechanically feed the crawler belt into the equipment while being unable to interfere with tire replacement; and meanwhile, the crawler belt is pushed by a gear rack to be arranged on excavator wheels.
本发明公开了一种挖掘机履带更换设备,包括机身,所述机身底壁内设置有可前后滑动的升降块,所述升降块内设置有若干上举丝杠腔,所述升降块后壁内设置有上举齿轮腔,所述上举齿轮腔内设置有通过蜗轮蜗杆配合丝杠螺母同时运用其自锁远离实现将挖掘机抬起的升降装置,本发明通过蜗轮蜗杆带动丝杠螺母配合自锁举起挖掘机用以更换履带,又通过圆锥块推动齿轮直径变换致使齿轮存在不会与更换轮胎发生干涉的同时用能通过机械将履带送入设备内,同时通过齿轮齿条推动履带装置挖掘机轮上。
