本文介绍了SQZ-1型潜孔钻车的结构,工作原理以及管锥式锚杆锚固轨床时钻车工作稳定性的分析。该钻车设计新颖,结构紧凑,集液压、电气、机械、操纵系统在同一钻车上。钻车采用轨轮非自行式。工作时采用直角座标移换孔位和管锥式锚杆锚固轨床;钻车一次“定位”后,即能钻凿同一方位,同一倾角的平行深孔。钻车工作稳定,操作简便。运输时可进入4号罐笼,可通过设置漏斗的巷道,进出峒室无需道岔。该钻车适应于深孔分段爆破法掘进天井,溜井和下向前倾60～90°,下向左右70～90°,采幅为2400mm的采场深孔。 This paper introduces the structure of SQZ-1 DTH drilling rig, its working principle and the analysis of the stability of drilling rig when it is anchored to the rail bed. The drilling design, compact structure, hydraulic, electrical, mechanical, control system in the same drilling vehicle. Drill wheel using non-self-propelled. Work using rectangular coordinates to change hole and pipe cone anchor bolt rail bed; Drilling a “positioning”, that can drill the same azimuth, the same angle of parallel deep hole. Drilling work is stable, easy to operate. Transport into the cage No. 4 can be set through the funnel roadway, access to the 峒 room without turnouts. The drilling rig is adapted to deep well borehole blasting method to excavate the well, and the well and the downhole are inclined to the depth of 60 ~ 90 ° and to the left and right by 70 ~ 90 ° with the width of 2400mm.
