タイトルまたは説明

The mechanical automatic unscrewing of drilling tools makes it easy to take out the gripper slip, expand its through-hole diameter, facilitate the lifting and lowering of coarse diameter drilling tools, reduce the labor intensity of workers, and improve the work efficiency. c. The single oil cylinder directly feeds and pulls the drilling tools, which is simple in structure, safe and reliable, and has large feeding and pulling capacity, improving the ability of the drilling rig to deal with accidents. d. The double pump system is adopted, and the rotary parameters and feed process parameters are adjusted independently. Variable oil pump and variable motor are combined for stepless speed regulation. The speed and torque can be adjusted in a large range, which improves the adaptability of the drill to different drilling processes.
