Frame foundation type emulsion drilling machine for coal mine

Abstract

The invention discloses a frame foundation type emulsion drilling machine for coal mine in the field of underground coal mines. The frame foundation type emulsion drilling machine comprises a drillingstand, a propulsion cylinder and a reversing valve, wherein the drilling stand consists of two groups of symmetrical sliding rods, two ends of each of the two groups of sliding rods are fixedly connected through a connecting plate, a supporting mechanism is fixedly connected to the lower end of the connecting plate, and a fixing plate and a reinforcing mechanism are symmetrically mounted at the front and rear ends of the drilling stand; the fixing plate and the reinforcing mechanism are fixedly connected with a sliding rod through bolts, a mounting base allowing a propelling cylinder to be mounted is fixedly connected to the upper end of the fixing plate, the propelling mechanism is movably arranged on the drilling frame, an emulsion motor is mounted at the upper end of the propelling mechanism, and the power end of the emulsion motor is fixedly connected with a drilling rod; and the emulsion motor and the propelling cylinder are connected with a reversing valve through a high-pressure rubber pipe. During assembly, a matched air compressor or power supply facility is not needed, assembly is easy, stability is good, deflection is not liable to happen, the drilling angle can be adjusted, operation can be conducted by another two persons, labor is saved, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the field of underground coal mines, which can be used for pre-splitting blast holes, water injection holes, gas release holes in outburst coal seams, etc. in coal wall construction of fully mechanized mining working faces in coal mines, and specifically relates to a frame-type emulsion drilling rig for coal mines. Background technique [0002] Coal mines are areas where human beings exploit coal resources in coal-rich mining areas, and are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far away from the surface, it is generally selected to excavate the coal by digging the roadway underground, which is an underground coal mine. Underground coal mines have a complete production process, coal transportation system, power supply system, communication dispatching system, ventilation system, production management, and living service facilities. According to the natural conditions of the...

AI Technical Summary

Problems solved by technology

In the above situations, it is necessary to drill holes in the coal wall of the coal mining face. However, the traditional construction process using pneumatic drilling rigs is not only cumbersome (need to prepare long-distance compressed air pipelines), but also requires separate installation of air compressors, resulting in a large number of construction workers. , low construction efficiency, poor safety and other shortcomings
