Mineral deep hole drilling carriage unit

Abstract

The invention relates to a mineral deep hole drilling carriage unit, which comprises a main engine and a pump station. The main engine comprises a stand (1), crawler devices (2) and a work mechanism (3), wherein the crawler devices (2) are arranged at the two sides of the stand (1); the work mechanism (3) is arranged on the stand (1). The work mechanism comprises a rotary chassis (3.1), an upright post (3.2), an upper support post (3.3) and a sliding assembly (3.11). The mineral deep hole drilling carriage unit is characterized in that a first oil cylinder (3.4) is arranged in the upright post (3.2); an outer sleeve of the upright post (3.2) is provided with a middle sleeve (3.5); a piston rod of the first oil cylinder (3.4) is connected with the top end of the middle sleeve (3.5); the middle sleeve (3.5) and the outer sleeve of the upper support post (3.3) are provided with outer sleeves (3.8); one end of a second oil cylinder (3.9) is connected with the bottom of a side wall of the middle sleeve (3.5) through a connecting piece while the other end is connected with the top of a side wall of the outer sleeve (3.8) through the connecting piece; and a compensating oil cylinder (3.12) is aslant arranged between the sliding assembly (3.11) and the outer sleeve (3.8). The invention has the advantages of low height of the machine body, narrow width, large adjustable range of drilling angles, running flexibility and strong applicability.

Description

technical field [0001] The invention relates to a mine deep hole drilling rig unit, in particular to a coal mine drilling equipment for water exploration, gas exploration, fault detection, roof caving, water injection and the like traveling on hydraulic crawlers. It belongs to the technical field of high gas outburst drilling in coal mines. Background technique [0002] In the coal mining face of Gaotu coal mine, due to the existence of a large amount of gas in the coal seam, in order to ensure safe production and improve production efficiency, during the coal mining process, drilling rigs are often used to release gas gas to reduce gas hazards. [0003] The downhole operation site needs to be constantly changed. Even in the same place underground, the angle and height of drilling are different. When drilling, the upper support device needs to be used to support up and down, and then the carriage assembly needs to be lifted by the first oil cylinder. Positioning is followed...

AI Technical Summary

Problems solved by technology

In the existing deep-hole drilling rigs for mines, the carriage assembly only uses one first oil cylinder to lift, so that the overall height of the machine body is higher; secondly, because the adjustable height of the first oil cylinder is limited, the adjustable angle of the drilling angle is small, The maximum angle can only reach 45 degrees; in addition, the current mining deep hole drilling rig occupies a large space and has a wide body width, which is not flexible in operation in narrow and low roadways, and has poor applicability
