QD—0.6型长绳悬吊大抓斗是目前我国竖井建井期间抓岩出碴使用比较普遍的设备,是徐州煤矿机械厂的产品。它的工作原理是人工操作操纵阀(二位五通阀),控制配气阀,使抓斗汽缸内活塞上下移动,从而带动抓片开闭,达到抓岩的目的;而抓斗的上下移动是通过井下遥控地面悬吊稳车的正反转来实现的。 QD-0.6 long rope suspension big grab is the equipment used in our country’s shaft during the construction of rock ballast more common, is Xuzhou Coal Mine Machinery Factory products. Its working principle is to manually operate the control valve (two five-way valve), control the valve, the piston in the grab cylinder moves up and down, which led to the opening and closing gripper to achieve the purpose of grasping rock; and grab the up and down movement It is achieved through the down-and-down ground control of the steady suspension of the ground.
