During the construction process, it is composed of a slide device, a hydraulic motor, a planetary reducer, a driving gear, a driven gear, a power head housing, a drive sleeve, a buffer device and a pressure plate device. It uses a hydraulic motor to transmit power to the planetary reducer, and then transmits it to the driven gear through the driving gear, and finally transmits it to the drill rod of the rotary drilling rig through the drive sleeve connected to the driven gear.

[0003] Since the power head has many parts, the factory needs to frequently turn over the power head box during the welding and assembly process of the rotary drilling rig power head to weld and install the corresponding parts.
