摘　　要：介绍了无钻杆钻具的工作原理、基本组成、导向撑压板的运动规律和受力特点以及导向撑压器实现自锁功能的方法.钻孔试验和仿真结果表明,导向撑压器通过自动调整,能够实现导向和自锁功能,钻具工作稳定.The rodless drilling rig was introduced in terms of its operational principle, basic structure, the motions of the guiding and supporting board and the forces acting on it, and the method to realize self-locking for the guiding and supporting device. Trial drilling test and simulation results illustrate that the guiding and supporting device provides excellent guidance and support to the drilling rig, and the drilling rig works effectively.

关 键 词：无钻杆钻孔机 导向撑压器 自锁
