目前,很多矿山的巷道、采矿场、井下调车场以及铁路隧道建设中,都广泛采用杆柱支护。杆柱安装过程中存在的主要困难是还未有机械设备代替繁重的体力劳动。所以,各矿山及铁路建设部门,迫切需要安装杆柱的机械化设备。对于安装楔缝式杆柱,最重要的工序是冲装和拧紧。目前不少单位是用大锤冲装和人力拧紧,劳动强度大、效率低、也极不安全可靠。各矿山大都使用我厂生产的01—45伸缩凿岩机,它能可靠地满足安装楔缝式杆柱的冲装工序,但不能胜任拧紧螺母工序(因其停滞扭矩太低,仅达8～10公斤-米)。
At present, pillar support is widely used in the construction of roadways, mining sites, underground yards, and railway tunnels in many mines. The main difficulty in the installation of poles is that there is no mechanical equipment to replace the heavy physical labor. Therefore, each mine and railway construction department urgently needs to install pole-mechanized equipment. The most important procedure for installing a wedge joint is punching and tightening. At present, many units are filled with sledgehammers and are manually tightened. They are labor-intensive, inefficient and extremely insecure. Most of the mines use the 01-45 telescopic rock driller produced by our factory. It can reliably meet the process of installing wedge-joint poles, but it is not capable of tightening nuts. Because its stagnation torque is too low, it can only reach 8 to 10 kilograms. -Meter).
