为了解决较重工件在机床上的装卸问题,改善劳动条件,我厂二车间的工人师傅,自力更生,因陋就简,利用钢管制成一台气动摇臂吊(图示)。气动摇臂吊,主要由吊钩1、钢丝绳4、摇臂5、双向配气阀6、立柱7和气缸8等组成。双向配气阀是通过拉链操纵的(弹簧是使配气阀保持在中立位置的)。工作时,压缩空气经配气阀进入活塞上部,并使其向下运动,通过活塞杆端部的滑轮,则拉动钢绳向下,使吊钩升起。当压缩空气进 In order to solve the problem of loading and unloading heavier workpieces on the machine tool and improving the working conditions, the worker master of the second workshop in our factory relies on self-reliance to make a pneumatic rocker arm hoist (picture) by using steel pipe. Pneumatic rocker crane, mainly by the hook 1, 4 wire rope, rocker arm 5, two-way valve with 6, column 7 and cylinder 8 and other components. The bi-directional valve is operated by a zipper (the spring is used to hold the valve in a neutral position). In operation, the compressed air enters the upper piston through the valve and moves it downwards. Through the pulleys at the end of the piston rod, pull the rope down to raise the hook. When compressed air enters
