全方位钻机钻孔姿态调节装置研究

Research of All Directions Posture Adjustment Mechanism of Coal Mine Rig

通过对比与分析,提出了一种煤矿钻机用全方位钻孔姿态调节装置,并详细介绍了该装置的主要结构及工作原理。以某型钻机为例,对该装置的关键零部件进行了有限元分析及机构运动学分析和现场试验。试验结果表明:该装置能在液压阀的操纵下自动完成钻孔倾角、方位角及高度的调节,自动化程度高,满足现场使用要求。

Through comparison and analysis,a type of posture adjustment mechanism which can satisfy all directions drilling is presented. The main structure and working principle of the mechanism is detailed introduced. By taking a type of drilling rig as an example, the finite element analysis and kinematic analysis were conducted for the mechanism. The verification results both in the laboratory and at the site showed that the mechanism can adjust the vertical angle, horizontal angle and drilling height by using the hydraulic valves, and it has the characteristics of high automation degree, and it can satisfy the site requirements.
