兖州矿业(集团)公司北宿煤矿通过对车场道岔扳道器改造加装风动管路系统,解决了多年来车场道岔扳道器操作一直靠人工手动完成的问题,取得了良好的安全技术效果。由于无需油液作为工作介质,更不需要压力泵,制造成本低廉,具有普遍的推广价值。新研制的车场道岔风动操作装置是由气缸、控制阀、道岔、连杆和高压管5个部分组成,采用井下压缩空气作为动力。其工作原理如下:打开控制阀,压缩空气通过高压管从气缸活塞的上端进入,推动活塞向前运动,活塞带动连杆将道岔拉起合实,即可以
The North Lake Coal Mine of Yanzhou Mining (Group) Co., Ltd. has installed the pneumatic piping system for the turnout switchgear in the yard to solve the problem that the turn-off switchman has been manually and manually completed for many years and achieved good safety and technical effects. As no oil as a working medium, but do not need the pressure pump, low manufacturing costs, with a general promotion value. The newly developed turnout pneumatic operating device is composed of cylinder, control valve, turnout, connecting rod and high pressure pipe 5 parts, the use of underground compressed air as a driving force. Its working principle is as follows: Open the control valve, compressed air through the high-pressure pipe from the cylinder piston into the upper end, to promote the piston forward movement, the piston rod will pull the switch pull together, you can
