掘进巷道采用锚杆支护时,临时支护是必不可少的一道工序,其可靠与否直接影响锚杆支护作业的安全,临时支护技术是发展煤矿综合机械化掘进的关键因素之一。在掘进机上配置机载临时支护装置,从根本上改变了传统临时支护的功能和形式。通过有效地给顶板施加初撑力,避免了工人在空顶区作业,增加了锚护作业时工作人员的安全性;实现了锚网的机械化铺架,降低了工人的劳动强度;机载临时支护装置用时展开,不用时折叠,液压缸驱动,减少了支护辅助时间,提高了掘进效率,操作简易、方便;与不同样式掘进机有机结合,不影响掘进机自身性能。
When using bolting support, the temporary support is an indispensable working procedure. The dependability of it or not has a direct impact on the safety of the bolting operation. The temporary support technology is one of the key factors for the development of mechanized coal heading. The provision of airborne temporary support on the roadheader has fundamentally changed the function and form of the traditional temporary support. By effectively exerting the initial support force on the roof, the workers are prevented from working in the empty top area and the safety of the staff in the anchoring operation is increased; the mechanized layout of the anchor net is realized and the labor intensity of the workers is reduced; the airborne temporary Support device with the time to start, when not folding, hydraulic cylinder drive, reducing the support time and improve the driving efficiency, easy operation, convenient; and different styles of roadheader organic combination, does not affect the performance of boring machine itself.
