摘要/Abstract

摘要： 液压凿岩机在凿钻过程中会产生炮孔偏斜,因此会严重阻碍其钻孔效率。工程实践表明:凿岩推进力的不均是造成凿岩炮孔偏斜的主要原因。为此,设计一种推进压力控制阀用于控制凿岩机推进机构施加的凿岩推进力。通过对该推进压力控制阀系统进行理论分析和数学建模,并进行仿真分析研究,仿真结果验证了该推进压力控制阀系统可自动调节出口工作压力,达到其预想的效果,为控制凿岩机推进机构凿岩推进力以改善凿岩钻孔效果提供了一种切实可行的技术思路。

Abstract: Hydraulic drilling machine will produce blast-hole deflection in the drilling process;it will seriously hamper the drilling efficiency.The engineering practice shows that the drilling force is mainly caused by the uneven drilling-hole deviation.Therefore,to promote the design of a pressure control valve is applied for controlling the drill propulsion mechanism of propulsion.The boost pressure control valve system by theoretical analysis and mathematical modeling and simulation analysis,the simulation results show that the boost pressure control valve system can automatically adjust the outlet pressure of work,to achieve its desired effect.In order to control the drill drilling thrust propulsion mechanism to improve the effect of rock drilling provides a feasible technical ideas.

Key words: advance pressure control valve, hydraulic drilling process, deflection, digital simulation
