Problems solved by technology

The cement mortar sealing method is labor-intensive, low in efficiency, and the sealing effect is poor. After the water injection steel pipe is buried, it cannot be retrieved, leaving hidden dangers for coal mining operations; the polyurethane sealing method has low sealing strength and short sealing distance. Air leakage: The inner tube of the hole sealer used in the ordinary hole sealing method is also made of steel pipe, and the two ends of the outer casing are fixed on the water-injected steel pipe. When the pressure is sealed, the outer casing expands longitudinally and contracts axially, which is easy Break the connection between the outer casing and the water injection steel pipe, damage the hole sealing device, and fail to achieve the sealing effect

Embodiment 1

[0027] Embodiment one: see figure 1 and figure 2 , The clip-type hole sealer includes a closed support tube 1a. The annular tube wall of the closed support tube 1a is evenly distributed with drug intestinal cavities 11 , and the adjacent parts of each drug intestinal cavity 11 and the inner and outer surfaces of each drug intestinal cavity and the support tube are film layers 10 . Each medicine intestine cavity 11 is equipped with a medicine intestine, and the adjacent medicine intestines are respectively equipped with an expansion compound A and an expansion compound B, and the expansion compound A and the expansion compound B can rapidly expand and fix after being mixed. In the prior art, there are many materials that expand rapidly after the two solutions are mixed, and will not be described in detail.

[0028] In this embodiment, end caps 21 and 22 are respectively installed on the inner end and the outer end of the closed support tube 1a. A combination cutter is provi...

Embodiment 2

[0030] Embodiment two: see figure 1 and image 3 , the content is basically the same as that of Embodiment 1, and the same parts will not be repeated. The difference is that the combined tool includes an annular blade 65, and radially divergent blades 62 are fixed on the annular blade 65, and each blade 62 is respectively Corresponding to the film layer 10 of the intestinal cavity of the medicine.

Embodiment 3

[0031] Embodiment three: see figure 1 and Figure 4 , the content is basically the same as that of Embodiment 1, and the same parts will not be repeated. The difference is that the combined tool includes an annular blade 65, and radially divergent blades 62 are fixed on the annular blade 65, and each blade 62 is respectively Corresponding to the film layer 10 of the intestinal cavity of the medicine. A stay cord 4 is fixed on the annular blade 65 , and the stay cord 4 protrudes from the closed medicinal intestine cavity 11 .

Abstract

The invention relates to a magazine clip type hole packer, which comprises a closed or combined supporting pipe; annular powder gut cavities are uniformly distributed on the pipe wall of the supporting pipe; a powder gut is filled in each powder gut cavity; expansion powder A and expansion powder B are filled in the adjacent powder guts respectively, and the expansion powder A and the expansion powder B can be quickly expanded and fixed after being mixed; and a combined cutter is arranged at one end of the closed supporting pipe, the edges of blades of the combined cutter correspond to the powder guts respectively, meanwhile, a puller is fixed on the combined cutter, the puller passes through the pipe cavity or the powder gut cavities, and the other end of the puller extends out of the closed supporting pipe. The expansion powder A and the expansion powder B are delivered to the deep position of a drilled hole by using the supporting pipe, and the powder guts of the two kinds of powder are lacerated by using the cutter, so that the two kinds of powder are quickly reacted and expanded to pack the hole. The hole packer has a simple structure, and is practical, convenient and good in using effect.

Description

Technical field: [0001] The invention relates to a gas hole sealing device in the field of coal mines, in particular to a clip-type hole sealing device. Background technique: [0002] In the process of coal mining, gas drainage in advance is an effective method to solve coal and gas outburst, and both coal seam water injection and gas drainage need to be sealed. The currently used sealing methods mainly include cement mortar sealing method, polyurethane sealing method and hole sealing device sealing method. The cement mortar sealing method is labor-intensive, low in efficiency, and the sealing effect is poor. After the water injection steel pipe is buried, it cannot be retrieved, leaving hidden dangers for coal mining operations; the polyurethane sealing method has low sealing strength and short sealing distance. Air leakage: The inner pipe of the hole sealer used in the ordinary hole sealing method is also made of steel pipe, and the two ends of the outer casing are fixed ...
