目前,普通进口全液压凿岩台车在地下工程掘进作业中得到了广泛应用,但该类设备存在钻孔深度控制不精准,配套使用钻杆长度不可变,围岩石质和钻具磨损情况实时难掌握等弊端。为解决这些问题,以某型液压凿岩台车为例,在对液压凿岩台车钻孔作业存在的客观问题进行分析的基础上,详细介绍一种钻进控制系统的改进方法、工作过程及应用效果。实践证明,改进后的钻进控制系统成本低,安装方便,操作简单,效益可观。
At present, common imported full hydraulic drilling rigs have been widely used in underground engineering tunneling operations. However, the drilling depth control of such equipments is not accurate, and the length of drill pipe used is invariable. The surrounding rock quality and the wear of drilling tools Real-time difficult to master the drawbacks. In order to solve these problems, taking a hydraulic drilling rig as an example, based on the analysis of the objective problems existing in the drilling operation of the hydraulic drilling rig, this paper introduces in detail an improved method and working process of the drilling control system And the application effect. Practice has proved that the improved drilling control system has the advantages of low cost, convenient installation, simple operation and considerable benefits.
