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
The present invention relates to oil mining field, colliery, particularly relate to a kind of auger stem, specifically provide the strong destructive power jackrod structure in a kind of large aperture.
Background technology
At present, single pole bed hydraulic drill rig is a kind of colliery common equipment, the work such as spy water, firedamp drainage and geology pressure release are carried out by the probing of single group drilling rod, but the hole that the drilling rod of this equipment use bores, aperture is little, need repeatedly to carry out repeated work, and this drilling rod ventilates and water flowing can not take into account, and drilling efficiency is low, and result of use is poor, the inapplicable work of exploitation probing efficiently now, cannot meet the requirements of the times of large yield.
Summary of the invention
The drilling rod aperture that the object of the invention is to solve above-mentioned existence is little, and fully, personnel labor intensity is large, and the technical problems such as production efficiency is low, spy provides the strong destructive power jackrod structure in a kind of large aperture in work.
The invention provides the strong destructive power jackrod structure in a kind of large aperture, it is characterized in that: the strong destructive power jackrod structure in described large aperture comprises rear thread connector (1), spiral section (2), outer steel pipe (3), interior steel pipe (4), preceding thread connector (5), cushion pad (6), drill bit (7);
Wherein: the front end of outer steel pipe (3) is fixedly connected with preceding thread connector (5), the rear end of outer steel pipe (3) is fixedly connected with rear thread connector (1), interior steel pipe (4) is fixedly connected with between preceding thread connector (5) and rear thread connector (1), it is inner that interior steel pipe (4) is positioned at outer steel pipe (3), the periphery of outer steel pipe (3) is fixedly connected with spiral section (2), preceding thread connector (5) is designed with loop buffer pad (6), preceding thread connector (5) is provided with interchangeable bit (7).
The spiral that described spiral section (2) is T-shaped structure for section is cut into slices.
In described rear thread connector (1), annular snap block structure is installed.
Advantage of the present invention:
The strong destructive power jackrod structure in large aperture of the present invention, has simple and reasonable, and be applicable to large aperture probing, destructive power is strong, and result of use is good, improves the conveying capacity of coal, the advantages such as drill bit can be changed in real time, easy for installation.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the present invention is further detailed explanation:
Fig. 1 is theory structure schematic diagram of the present invention.
Detailed description of the invention
