[0002] Rotary drilling rigs have been rapidly promoted and applied in construction projects due to their advantages of high efficiency, speed, environmental friendliness, and high-quality hole formation. Rotary drilling rigs, when used with different drilling tools, can adapt to construction in most soil layers and both soft and hard strata. The drilling methods of rotary drilling rigs generally employ wet rotary drilling with static mud wall support and dry rotary drilling without stabilizing fluid. For soft soil, marine silt layers, and some special strata, full-casing rotary drilling is required, and the power head on the rotary drilling rig is an important component of this method.
[0003] In the prior art, patent document with publication number (CN211397429U) mentions a power head for a rotary drilling rig, including a fixed frame and a disassembly and installation mechanism. The disassembly and installation mechanism is located on the fixed frame and includes a mounting hole located in the middle of the fixed frame. The power head body passes through the interior of the mounting hole, and a reserved groove is provided on the side of the mounting hole. The lower end of a first rotating shaft is installed at the bottom of the reserved groove, and the upper end of the first rotating shaft passes through the top of the fixed frame and is connected to a handle. A first hammer-shaped gear is fixed to the outer wall of the first rotating shaft, and a second movable ring is located inside the movable groove. This prior art allows eight lead screws and eight limiting grooves to be simultaneously separated or engaged by rotating the handle, thereby facilitating the disassembly and installation of the power head body.
