KY-500 full hydraulic tunnel drilling rig

Reducing the auxiliary time of pipe delivery and increasing the pure drilling time, the deeper the drilling hole, the more obvious the economic effect. Relieve workers of physical labor. The core blockage can be extracted immediately and the core extraction rate can be improved. Reduce the wear and tear of drill pipe thread, extend the life of drill pipe and reduce pipe consumption. Reduce the bit's hole sweeping wear, unscrewing and the chance of collision with the hole wall, and extend the bit life. Reduce flushing fluid suction and hole wall pressure imbalance, thereby reducing hole accidents. Reduce mechanical wear of the drill and increase the service life of the drill. Reduce borehole curvature and improve borehole quality. It is conducive to drilling into complex strata and avoiding hole wall collapse. The inclinometer can be placed in the drill pipe by the steel cable to measure the inclinometer.
