A butterfly twist drill extraction tool and its drilling and extraction method, the butterfly twist drill extraction tool at least includes a drilling platform, a round cake slotted drill pipe, a DC motor, a motor fixing device, a commutator connection terminal, and a gear , steel handle, clamping structure, clamping structure control switch handle and twist drill; the drilling platform includes five parts: rectangular base, electro-hydraulic jack, steel tower structure, cylindrical groove, steel outsourcing structure; steel outsourcing structure Set on the front and rear sides above the steel tower structure, the motor fixing device is fixed between the front and rear two-layer steel outsourcing structure, the DC motor is connected with the gear flat key through the motor fixing device; the upper end of the round cake slotted drill pipe is clamped The structural clamp is set in the middle groove of the steel handle. The invention combines the electro-hydraulic jack and the compound transmission of the motor gear, and has three functions of drilling, continuous lifting and automatic drilling, saves a lot of manpower, and significantly improves the drilling efficiency and quality.
Description
technical field [0001] The invention relates to the technical field of geotechnical engineering investigation and drilling of power transmission lines, in particular to a butterfly twist drill pulling tool and a drilling pulling method thereof. Background technique [0002] The geotechnical engineering survey of transmission lines is an important part of the survey in the power industry, especially the stability of the transmission line tower is the basic condition to ensure the normal operation of the overhead transmission line. , drilling costs and other factors, currently in the geotechnical investigation of transmission lines, the most widely used drilling tool is still the original hand twist drill. [0003] In the actual drilling operation, with the increase of the drilling depth and the change of the strength of the underground soil layer, sometimes after the twist drill bit carries the soil, it is very difficult to pull out the drill pipe, and sometimes even 3 to 4 p...
