摘　　要：目前分体式潜孔钻车仍占据国内大多数露天矿山中小孔径爆破孔的钻凿市场,其中双齿轮泵驱动的潜孔钻车因性价比高、易维护保养而大量使用,但该类型钻车钻孔作业时存在液压系统效率低,回路压力及流量稳定性差等问题。本文以双齿轮泵驱动的潜孔钻车为研究对象,在分析现有产品的设计方案的基础上提出一种新型液压系统设计方案,并通过Amesim软件将该方案同市场常见方案做了对比分析。Today,split DTH drilling rigs still dominate the market segment of drilling small-diameter blastholes in the majority of domestic open-pit mines.DTH drilling rigs with double gear pump–driving hydraulic systems have seen extensive applications duo to their high cost performance and easy to maintenance.However,these drilling rigs show some problems like low efficiency of hydraulic systems,unreliable pressure and flow in returning circuits.Targeting at DTH drilling rigs with double gear pump–driving hydraulic system,the paper puts forward a new design plan for the hydraulic system and makes a comparison with the common design plans in market using Amesim software,on the basis of analyzing the design plan of existing product.
