HB4——160型缓倾斜薄煤层双伸缩自移式液压支架,为松藻矿区打通—矿七号层设计的,由松藻矿区机修厂承担样机试制任务.液压支架零部件机械加工精度要求高、工艺复杂,工装准备时间短.对于人员少,设备简陋的小厂来说,任务是很重的.在毛主席革命路线的指引下,在上级党委的支持关怀和液压支架“三结合”研制领导小组的部署下,机修厂会同重庆煤炭研究所成立“三结合”试制小组,发动群众大搞试制会战,抓了产品质量,按计划完成试制任务.承各有关兄弟单位的支援、协助,给我们及时解决乳化泵站、密封件和尼龙导向件材料等,保证了支架能按期下井试验.
HB4--160 slow-inclined thin seam double telescopic self-moving hydraulic support for the Songzao mine opened up - the seventh floor of the mine designed by the Songzao mine mechanic factory prototype to undertake the task of testing hydraulic support parts machining accuracy requirements , The process is complex, tooling preparation time is short.For the small, poorly equipped small factory, the task is very heavy.In the revolutionary direction of Chairman Mao under the guidance of the superior party committee’s supportive care and hydraulic stent “triple combination” development Under the deployment of the leading group, the machine repair factory will set up a “three-in-one” trial group with the Chongqing Coal Research Institute to mobilize the masses to vigorously carry out trial battles, grasp the quality of products and complete the trial-production tasks according to plan. We promptly solve the emulsion pump station, seals and nylon guide material, to ensure that the stent can go down on schedule test.
