Description

Technical Field

[0001] The utility model relates to the technical field of gas extraction, in particular to an extraction device for gas disaster management. Background Art

[0002] Mine gas is a general term for various harmful gases, mainly methane, that emerge from coal and rock during coal production. It is the main natural factor that seriously threatens coal mine safety production. The casualties and property losses caused by gas disasters are huge. Therefore, preventing gas disasters is of great significance to the healthy and sustainable development of the coal industry.

[0003] At present, gas extraction is an important means of controlling gas in mine operations, and the basic process of gas extraction is to first drill a hole in the coal seam with a drilling rig, and then insert a gas extraction pipe into the borehole after withdrawing the drill rod and drill bit. The gas extraction pipe must be exposed to a certain distance from the borehole, and then a sealer or filling material is used to seal the gap between the gas extraction pipe and the inner wall of the borehole at the hole mouth. Finally, the gas extraction equipment is connected to the end of the gas extraction pipe, and the equipment is started to extract the gas. Therefore, the extraction pipe needs to be effectively installed before gas extraction.

[0004] After searching, it is proposed in a stable gas extraction pipe support with patent publication number CN202321126716.7 that "the utility model provides a stable and reliable gas pipe support, which does not require other parts for fixing, is easy to load and unload, and has good stability of the gas pipe, thus solving the problems of the prior art in which loading and unloading is troublesome, and the gas pipe is easy to sink, causing deformation and damage of the roof and the two sides".

[0005] However, the above scheme still has certain shortcomings in actual use. When using this scheme, it is necessary to install foot nails in advance to achieve the effect of auxiliary support for the bracket. This installation method will make the installation and disassembly process of the extraction tube more cumbersome. At the same time, it is also impossible to insert the extraction tube into boreholes at different heights, which greatly reduces the extraction efficiency. Utility Model Content

The bottom of the base 101; the extraction tube clamping device 2 includes two lifting rods 201, and two mounting frames 202 are fixedly installed between the ends of the two lifting rods 201. The bottom ends of the mounting frames 202 are movably connected to the top of the mobile device 1 through a support seat 204.

A movable sleeve 303 is sleeved on the surface of the rotating shaft 302. An arc groove connected end to end is opened on the surface of the rotating shaft 302. A plug rod is fixedly installed on the inner wall of the movable sleeve 303. The plug rod overlaps the inner wall of the arc groove. A slip ring 305 is fixedly installed on the top of the movable sleeve 303. A hinge rod 306 is hinged on the top of the slip ring 305. A lifting platform 307 is hinged on the other end of the hinge rod 306. A lifting rod 308 is fixedly installed on the top of the lifting platform 307. The top of the lifting rod 308 extends to the top of the driving box 301 and is connected to the lifting box 307. The bottom end of the descending rod 201 is fixedly connected; by arranging the extraction tube clamping device 2 and the height adjustment device 3, the placement clamp 203 and the lifting clamp 206 included in the extraction tube clamping device 2 can be used to quickly clamp extraction tubes of different specifications, and the rotating shaft 302 included in the height adjustment device 3 can drive the lifting rod 308 above the hinged rod 306 through the movable sleeve 303 to adjust the height of the placement clamp 203 and the lifting clamp 206 as a whole, so that the device can insert extraction tubes of different sizes into boreholes of different heights, thereby significantly improving the practicability of the device.

[0023] Specifically, positioning holes are provided inside the bending rod 205 and inside the mounting frame 202 , and a positioning pin 207 is movably inserted between the positioning holes of the bending rod 205 and the mounting frame 202 .

[0024] In this embodiment, the positioning pin 207 can be used to perform positioning processing at different heights between the bending rod 205 and the mounting frame 202.

[0025] Specifically, a slide bar 304 is fixedly mounted on the inner wall of the driving box 301 , and the inner ring of the slip ring 305 is slidably connected to the surface of the slide bar 304 .

[0026] In this embodiment, the sliding ring 305 can slide along the surface of the sliding rod 304 along with the movable sleeve 303 , thereby improving the movement stability of the movable sleeve 303 .

[0027] When in use, the transmission crawler structure 102 is first started, so that the transmission crawler structure 102 drives the mobile base 101 to gradually move to the bottom of the drill hole, and then the transmission crawler structure 102 is stopped;

[0028] Next, the extraction tube is inserted into the extraction tube clamping device 2, so that the bottom end of the extraction tube overlaps with the inner sides of the two placement clamps 203, and then the bending rod 205 is pulled down, so that the bending rod 205 drives the lifting clamp 206 to descend synchronously, so that the inner side of the lifting clamp 206 contacts the top of the extraction tube, and then the positioning pin 207 is inserted into the inner side of the mounting frame 202, so that the mounting frame 202 and the bending rod 205 are mutually clamped by the positioning pin 207, so that the extraction tube is fixed between the placement clamp 203 and the lifting clamp 206;

[0029] Then, the height adjustment device 3 is started, so that the built-in motor inside the driving box 301 starts to drive the rotating shaft 302 to rotate, so that the arc grooves connected end to end on the surface of the rotating shaft 302 move, so that the openings of the arc grooves start to move synchronously. Since the movable sleeve 303 is fixedly connected to the inside with a follower rod, and the follower rod is located inside the arc groove, the movement of the arc groove drives the movable sleeve 303 to move along the surface of the rotating shaft 302 through the follower rod.

[0030] The displacement of the movable sleeve 303 will drive the articulated rod 306 to shift and deflect at an angle through the slip ring 305, so that the top of the articulated rod 306 can drive the lifting platform 307 to gradually lift up, prompting the lifting platform 307 to drive the two lifting rods 201 to move synchronously through the lifting rod 308, and the synchronous lifting of the two lifting rods 201 will jointly lift the extraction tube upward, so that the height of the clamped extraction tube can be adjusted.

[0031] To sum up, the extraction device for gas disaster management, by providing an extraction pipe clamping device 2 and a height adjustment device 3, can quickly clamp extraction pipes of different specifications by utilizing the placement clamp 203 and the lifting clamp 206 included in the extraction pipe clamping device 2, and the rotating shaft 302 included in the height adjustment device 3 can drive the lifting rod 308 above the hinged rod 306 through the movable sleeve 303 to adjust the height of the placement clamp 203 and the lifting clamp 206 as a whole, so that the device can insert extraction pipes of different sizes into boreholes of different heights, thereby significantly improving the practicability of the device.
