Butterfly type twist drill pulling tool and drilling pulling method thereof

Abstract

The invention provides a butterfly type twist drill pulling tool and a drilling pulling method thereof. The butterfly type twist drill pulling tool at least comprises a drilling platform, a round cake clamping groove drill rod, a direct current motor, a motor fixing device, a commutator connecting terminal, a gear, a steel handle, a clamping structure, a clamping structure control switch handle and a twist drill; the drilling platform comprises a rectangular base, an electric hydraulic jack, a steel tower structure, a cylindrical groove and steel wrapping structures; the steel wrapping structures are arranged on the front side and the rear side of the upper portion of the steel tower structure; the motor fixing device is fixed between the front steel wrapping structure and the rear steel wrapping structure; the direct current motor is connected with a gear flat key through the motor fixing device; and the upper end of the round cake clamping groove drill rod is clamped in a middle groove of the steel handle through the clamping structure. According to the butterfly type twist drill pulling tool and the drilling pulling method thereof, the electric hydraulic jack and composite transmission of the motor and the gear are combined, the functions of drilling, continuous pulling and automatic drill lifting are achieved, a large amount of manpower is saved, and the drilling efficiency and quality are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering investigation and drilling for power transmission lines, in particular to a butterfly twist drill extraction tool and a drilling and extraction method thereof. Background technique [0002] The geotechnical engineering investigation of transmission lines is an important link in the investigation of the electric power industry, especially the stability of transmission line towers is the basic condition to ensure the normal operation of overhead transmission lines. , drilling cost and other factors, at present in the geotechnical engineering investigation of transmission lines, the most widely used drilling tool is still the original hand-cranked 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 it is very difficult to pull out the drill pipe after the twist drill bi...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a butterfly-type twist drill pulling tool for the problems of dismantling and assembling the drill pipe, insufficient drilling load, difficulty in pulling out and lifting the drill during the drilling process of the existing hand-operated twist drill. And its drilling and pulling method realizes the three functions of drilling, continuous pulling and automatic drilling, saves a lot of manpower, and significantly improves the drilling efficiency and quality
