由挖掘机改装而成的钻机(如挖掘钻进机、切削钻机、液压凿岩钻机等)因具有单杆成孔深、工作效率高、运行成本低、操作舒适、性能可靠等优点,在市场上广受欢迎。华力重工HL315DR型切削钻机单杆钻孔深度可达5.5m,为了进一步提高该型切削钻机钻孔的导向性能、成孔质量和工作效率,我们对该钻机钻杆的限位导向装置进行了改进。1.结构和存在问题(1)结构华力重工HL315DR型切削钻机的钻臂底部设置了钻杆限位导向装置,该装置对钻杆的限位导向性能和钻孔质量
Drilling rigs modified by excavators (such as excavation drilling machines, cutting drilling rigs, hydraulic rock drilling rigs, etc.) have the advantages of single hole forming depth, high working efficiency, low running cost, comfortable operation and reliable performance. Popular on the. In order to further improve the drilling performance, hole forming quality and work efficiency of the drilling rig of HRL, HL315DR drilling rig with single rod drilling depth of up to 5.5m was carried out on the limit guide of the drilling rod Improve. 1. Structure and Existing Problems (1) Structure The drill rod limit guide is arranged on the bottom of the boom of the HL315DR cutting drill of HRL Heavy Industries. The device has the function of limiting guide performance and drilling quality
