Mining drilling machine

Abstract

The invention relates to the field of mining machinery, in particular to a mining drilling machine. The mining drilling machine comprises a drilling machine platform and a drilling machine body arranged on the drilling machine platform, a power head and a guide rail used for guiding the power head to move linearly are arranged on the drilling machine body, and a clamping seat used for clamping a drilling rod is arranged on the guide rail. The mining drilling machine is characterized in that an automatic rod replacing device and an aerial fog mechanism are arranged on the guide rail of the drilling machine body, an adjusting mechanism used for controlling the drilling machine body to execute corresponding actions is installed on the drilling machine platform, and the end, away from the drilling machine platform, of the adjusting mechanism is connected with the guide rail. The provided drilling machine has the functions of automatically changing rods, cooling and dedusting, the position of the drilling machine is adjusted more conveniently, and adaptability is higher.

Description

technical field [0001] The invention relates to the field of mining machinery, in particular to a mining drilling rig. Background technique [0002] In coal production engineering, a large number of roadways need to be excavated. In order to reduce the cost of roadway excavation and improve the stability of surrounding rock, it is necessary to reinforce the rocks around the roadway. With the mining of coal in mines year by year, the mining depth is gradually increasing. In recent years, with the increase of mining depth, there have been more and more roadway floor heaves. After the roadway floor heave is deformed, the cross section is reduced, which affects transportation, ventilation and personnel walking. Conducive to mine safety production. The floor drum is a technical problem that needs to be solved in coal mining. The commonly used method of controlling the deformation of the floor drum is mainly to implement floor grouting reinforcement. Reinforcement and reconstruc...

Problems solved by technology

With the mining of coal in mines year by year, the mining depth is gradually increasing. In recent years, with the increase of mining depth, there have been more and more roadway floor heaving phenomena. After the roadway floor heaving is deformed, the cross section is reduced, which affects transportation, ventilation and personnel walking. Conducive to mine safety production

The bottom drum is a technical problem that needs to be solved in coal mining. The commonly used bottom drum deformation control method is mainly to implement floor grouting reinforcement. Reinforcement and reconstruction generally use mining drilling rigs to drill holes in roadways with large cross-sections. However, the existing mining drilling rigs still have the following shortcomings during construction. The required manual workload is large, the work intensity is high, the efficiency is low, and there are great safety hazards; 2. The existing mining drilling rigs are in harsh environments such as the fuselage cannot be rotated in the narrow mine tunnel, obstacles are blocked, and ditches are restricted. Work normally under working conditions; 3. It is impossible to cool the drill pipe that heats up during work in time
