Abstract

A large-diameter drilling rod structure with strong destructive power is characterized in that the large-diameter drilling rod structure with strong destructive power comprises a rear threaded connector, a spiral slice, an outer steel pipe, an inner steel pipe, a front threaded connector, a bumper pad and a drill bit; the front end of the outer steel pipe is fixedly connected with the front threaded connector; the rear end of the outer steel pipe is fixedly connected with the rear threaded connector; the inner steel pipe is fixedly connected between the front threaded connector and the rear threaded connector; the inner steel pipe is positioned in the outer steel pipe; the periphery of the outer steel pipe is fixedly connected with the spiral slice; the front threaded connector is designed with the annular bumper pad; the front threaded connector is equipped with the interchangeable drill bit; an annular fixture block type structure is installed in the rear threaded connector; and the profile of the spiral slice is of a T-shaped structure. The large-diameter drilling rod structure with strong destructive power has the advantages that the large-diameter drilling rod structure with strong destructive power is simple and reasonable, and is suitable for large-size hole drilling, the destructive power is strong, the using effect is good, coal transmission capacity is improved, the drill bit can be changed in real time, and installation is convenient.

Description

technical field [0001] The invention relates to the field of coal mine oil well exploitation, in particular to an auger drill rod, and in particular provides a drill rod structure with a large aperture and strong destructive force. Background technique [0002] At present, the single-rod bed hydraulic drilling rig is a commonly used equipment in coal mines. It uses a single set of drill pipes to perform work such as water exploration, gas discharge, and geological pressure relief. Repeated work is required for many times, and the ventilation and water passage of this drill pipe can not be considered at the same time, the drilling efficiency is low, and the use effect is poor. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned technical problems such as small drill pipe diameter, sufficient work, high labor intensity and low mining efficiency, and specially provides a large diameter and strong destructive force drill pipe...
