Abstract

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.
