Large-aperture pressure relief drilling machine

Abstract

The invention discloses a large-aperture pressure relief drilling machine, which comprises a movement foundation bed and a track unit, wherein the track unit is provided with a mechanical movement part; the mechanical movement part comprises a working end, wherein the track unit on the same side of the working end is laterally fixedly provided with a front vise of a hollow beam shape; the workingend is provided with an annular ring beam; two sides of the front vise are independently provided with a disassembling device; the track unit is provided with a rear vise for disassembling a drill rod, and a bracket used for supporting the drill rod; and the center of the bracket is positioned on an axial line from the working end to the front vise. The large-aperture pressure relief drilling machine has the beneficial effects that the pushing and the drilling of the drill rod can be realized through the front vise, the bracket and the rear vise of the same structure, automatic disassembling can be realized, manpower is saved, and working efficiency is improved. By use of a mechanical operation, a large-diameter drill rod which exceeds a manpower bearing range can be used, and the efficiency of the pressure relief drilling machine is improved by one level.

Description

technical field [0001] The invention relates to the field of mining machinery, in particular to a large-aperture pressure relief drilling rig. Background technique [0002] With the increase of depth and strength of coal mining, rock bursts become more and more frequent, and the resulting losses are also increasing. At present, one of the main measures for coal mine erosion prevention is to drill holes in the coal seam to release the pressure of the coal seam. Use a pressure relief drill for pressure relief work. Most of the currently known pressure relief drilling rigs only include the working part of linear push, the power part of torque output, and the drill pipe drilled into the rock formation. Since the position required for pressure relief is deep in the ground, general drilling rigs use multiple Drill holes for pressure relief by assembling the joint at the first place, and use the helical blades on the drill pipe to drill holes in the rock formation. [0003] But b...
