一种适合缓倾斜矿体穿孔作业的露天潜孔钻机——KQX-150型潜孔钻机近日在江西萍乡通过技术鉴定。KQX—150型潜孔钻机自带空压机,除具有潜孔钻机的共性外,该机自重28t,具有较低的整机重心和较好的整机附着性能,能稳定在纵向26°、横向14°斜坡上钻孔作业;钻时的部分辅助工作机构采用液压技术,如双液压缸举升钻架,液压卡盘钻架定位,采用液压送杆和卡杆,使接卸杆自动化。样机在攀钢石灰石矿进行工业试验。1987年因用户需要该厂又试产一台
One kind of open-hole and down-hole drilling machine suitable for perforation work of gently inclined ore body - KQX-150 DTH drilling rig recently passed technical appraisal in Pingxiang of Jiangxi Province. KQX-150 DTH drilling machine comes with air compressor, in addition to the commonality with the DTH drilling rig, the weight of the machine 28t, with a lower center of gravity and better overall machine adhesion performance, stable in the longitudinal 26 °, Horizontal 14 ° slope on the drilling operation; part of the drilling work auxiliary mechanism using hydraulic technology, such as double hydraulic cylinder lifting drill frame, hydraulic chuck drill positioning, the use of hydraulic delivery rod and the rod, so that the rod automatic. Prototype industrial test in Pangang limestone mine. In 1987 due to user needs the plant and trial production of a
