在钻探施工中,打吊锤处理卡钻等事故是常用的一种方法.但是,打吊锤往往要花费很多人力和时间.有时因人力不够,工具不齐,拖延了时间,造成事故恶化.远离队部单机生产的机台打吊锤更为困难.此外,打吊锤是在地表进行,冲击功靠钻杆柱传递,在钻孔比较深的情况下,传到事故钻具处的冲击功是很小的,不但事倍功半,而且容易发生人身和机械事故. In drill construction, it is a commonly used method to deal with accidents such as stuck-drills, etc. However, it often takes a lot of manpower and time to do heavy lifting, sometimes due to lack of manpower, lack of tools, and delay of time, resulting in deterioration of the accident. Far from the team unit production of single machine crane hammer more difficult.In addition, playing hammer is carried out on the surface, the impact of work by the drill string transmission, in the case of deeper drilling, reached the accident at the impact of the drill Work is very small, not only more effective, but also prone to personal and mechanical accidents.
