钻机主要用于井下钻各类工程孔,辅助煤矿开采,以确保采矿工作中的人员安全。钻机要求布局紧凑、操纵便利。第一发展阶段,一个世纪前出现了手把给进式钻机,由人力驱动,经过蒸气机发展到由柴油机或电动机驱动阶段。其代表型号为XB-300、HQ-150等,这类钻机特点是:结构简单、易于制造、成本低廉,但是其机构笨重,机械化程度低,劳动强度大,操作分散,占用劳动力多,安全可靠性差,成为该类钻机的致命弱点。因其技术参数落后,不能精确控制,钻孔效率过低,现阶段很少使用。第二发展阶段,这个阶段钻机的特点是使
Drilling rig is mainly used for drilling all types of engineering holes underground, supporting coal mining, mining personnel in the work to ensure safety. Rig requirements compact layout, easy handling. In the first stage of development, a hand-fed feed rig appeared a century ago and was manpower-driven and developed by a steam engine into a diesel or electric motor-driven stage. Its representative model is XB-300, HQ-150 and so on. Such drilling rigs are characterized by simple structure, easy manufacture and low cost, but the mechanism is heavy and heavy, the mechanization degree is low, the labor intensity is large, the operation is scattered, the labor force is occupied, the safety and reliability Poor sex, a fatal weakness of such drilling rig. Because of its backward technical parameters, can not be precisely controlled, drilling efficiency is too low, rarely used at this stage. The second stage of development, this stage rig is characterized by
