摘    要：通过综合分析潜孔钻机接卸钻杆装置,提出了全液压接卸钻杆装置的结构方案及液压控制系统,研究了夹杆缸的结构及夹杆爪与夹杆缸的联接方式,研制了夹杆缸双行程及夹杆缸活套联接结构的夹杆器,分析了夹杆缸结构参数与工作参数的相互关系.针对现有接卸钻杆装置钻杆的夹持力过大,降低钻杆使用寿命问题,根据材料的接触强度理论与变形理论,对钻杆合理夹持力进行了研究,并提出了夹杆爪的设计方法.实践结果表明,所研制的全液压接卸钻杆装置操作快捷方便,具有良好的接卸钻杆、接卸钻头和钻机开孔导向控制功能.

Abstract: Based on the analysis of the current rod breakers of down-hole drill, the structural program and hydraulic system of the fully hydraulic rod breaker are proposed. The clamping cylinder structure and the attaching way between the clamping cylinder and the jaw are studied,the correlation between the structural parameters of the clamping cylinder and its working parameters and the rod-clamping with novel style are put forward. In view of the service life of the current rod breaker affected by the clamping force, the design way of the jaw and the study method of reasonable clamping are studied. The experiment results show that the rod breaker can be easily operated, and that it has fine functions of jointingbreaking rods, jointing-breaking drill bit and guiding on opening hole.
