| 摘 要： | 根据对液压凿岩卡钎机理的分析,针对3种不同的卡钎现象,在采用 "绝对变化量"控制条件的基础上,应用计算机技术,提出推进力、回转扭矩的"变化率"控制条件,更准确地对可能出现的卡钎种类进行判定,实现"二路反馈三级防卡"的"主动预防"和"被动防卡"的设想.提出"开关式"和"无级调节式"两种处理方案,防卡钎的同时兼顾钻孔效率.

| Abstract: | Based on the analysis of blockage mechanism of hydraulic rock drill and aimed at three different blockage phenomena,the control condition of variation rate of propulsive force and rotational torque was presented on the basis of control condition of absolute variation and computer technology,so that the kind of drill blockage that would possibly take place would be more accurately identified and the tentative ideas of active prevention and passive blockage prevention were well implemented with two-path feedb... |
