| Abstract: | Aiming at the problems that pre-tightening of large diameter drill pipe for directional drilling rig depends on manual operation with high labor intensity and high safety risk, a design scheme of auxiliary loading drill pipe mechanism for directional drilling rig was presented, and the main points of its structural design were described in detail. The transmission sketch of drill pipe mechanism on friction wheel was obtained by force analysis, and its transmission parameters were calculated and checked. The auxiliary loading drill pipe mechanism has simple structure, small size and can slip and protect drill pipe screw when overloading. It provides a solution to the problem of loading large diameter drill pipe for directional drilling rig. |
