Description

Technical Field

[0002] Rock burst is a phenomenon in which the elastic deformation energy accumulated in the rock mass is suddenly and violently released under certain conditions, causing the rock to burst and eject. Rock burst can also cause a large amount of rock to collapse and produce loud noises and air wave impacts, which can not only destroy mines, but also endanger ground buildings with shock waves. Among the monitoring methods for rock burst danger, the drill cuttings method judges the stress concentration in the rock mass based on the amount of drill cuttings discharged when drilling at different depths and their changing patterns, and identifies the tendency and location of rock burst. When the rock burst danger is monitored, a pressure relief drill hole is constructed by drilling pressure relief. The pressure relief drill hole is drilled and pressure relieved by a small handheld drill.

[0024] Compared with the prior art, the invention has the following beneficial effects: the anti-collision drilling machine for underground coal mine pressure relief is

[0025] (1) A fixing device is provided. When the punching and drilling machine body is manually installed on the upper side of the force-bearing plate through the installation groove group, the through block on one side of the installation plate is manually inserted through the installation plate to fix the punching and drilling machine body. After the punching and drilling machine body and the force-bearing plate are fixed, the punching and drilling machine body can be driven to work during the force contact process of the punching and drilling machine body switch by driving the cylinder. When the punching and drilling machine body is installed on the upper side of the fixing device, it is avoided that the hand strength is needed to support and straighten the hole.

At the same time, the above-mentioned situations are avoided in sequence through the above-mentioned structural parts;

[0027] (3) An adjustment locking device is provided. When the through frame is subjected to force movement, the double-hole connecting plate group drives the connecting roller and the inverted teeth to move relative to each other, and the through frame is subjected to force movement, the installation plate group is driven to move in the same direction. At the same time, the plate installation frame moves in the same direction during the force movement of the installation plate group. When the installation frame is subjected to force adjustment at a corresponding position distance, the telescopic cylinder drives the double-hole connecting plate group to move relative to each other, and the double-hole connecting plate group is subjected to force relative movement, and the connecting roller and the inverted teeth are driven to make limited contact. The above device can play an adjustment limit locking effect on the adjusted punching and drilling machine body, thereby avoiding the problem that the drill bit is easily broken due to the operator's inadvertent control of the multi-stage telescopic cylinder driving process;

[0029] (5) A movable wheel, a first hydraulic telescopic rod and a ground spike are provided, and the movable wheel is used to drive the entire device to move during the force movement, so that the entire device can be conveniently driven to move and adjust during the force movement. At the same time, the first hydraulic telescopic rod is used to drive the ground spike to move during operation.
