摘　　要：综采放顶煤工作面,传统拉后部输送机的千斤顶采用倒拉方式,存在着千斤顶力量不能完全发挥,拉移力不够大、加大拉移千斤顶后布置空间受限、放顶煤时拉移千斤顶活塞杆一直裸露在外容易损坏电镀层等问题;现设计一种新的移后部输送机的结构型式,彻底解决倒拉存在的一些问题。Fully mechanized caving coal face, pull transport adopts the jack at the back of the traditional way, the existence of moving power jack can′t play to pull force is not big enough, increase the pull move jack after decorate a space constrained, pull when coal moving jack piston rod has been exposed easily damaged plating, etc.; Now design a new move back conveyor′ s structure completely solve some problems.
