煤矿坑道钻机用多功能手动夹持器的研制

Development of Multifunctional Manual Clamper for Coal Mine Tunnel Drilling Rig

结合ZDY750L型分体履带式全液压坑道钻机结构特点及现有钻机夹持器存在的问题,研制了一种集手动夹持装置、钻杆扶正机构及集尘装置为一体的新型钻机用多功能手动夹持器。介绍了夹持器的结构组成与工作原理,并利用有限元分析软件验证了关键部件卡板的强度。工业性试验表明,夹持器结构设计合理、操作方便、开合灵活,有效保证了钻孔效率,满足安全生产需要。

Combined with the structural characteristics of the ZDY750L split crawler hydraulic tunnel drilling rig and the problems existing in the clamper of the drilling rig,a new type of multifunctional manual gripper with manual clamping device,drill pipe rig device and dust collecting device was developed.The structure and working principle of the clamper were introduced,and the strength of snap-board was verified by the finite element analysis software,which was the key component of the clamper.The industrial test shows that the clamping is reasonable in design,convenient in operation and flexible in opening and closing,which can guarantee the drilling efficiency and meet the needs of safety production.
