Abstract
The utility model discloses a hole sealing device with an annular air bag, which is applicable to gas extraction from a drilled hole in a coal layer and hole sealing by slurry injection under a coal mine. The hole sealing device comprises an inflation device consisting of an inflation joint, a pressure pipe, a ball valve, a pressure meter and an inflation pump and also comprises a hole sealing plug, wherein the hole sealing plug comprises the annular air bag; a supporting ring is arranged at the front end of the annular air bag; two buckled semi-supporting rings are arranged at the rear end of the annular air bag; a gap is formed between the two buckled semi-supporting rings; and an air nozzle matched with the inflation joint is arranged at the gap. According to the hole sealing device, the problems that the existing plug cannot be sent to a right position and plugs a hole loosely are solved; and before inflation, the outer diameter of the plug of the air bag is greater than a diameter clearance of the drilled hole, so that the plug can be smoothly sent to an appointed position.
Description
Technical field
The utility model relates to a kind of hole sealing device, is particularly useful under a kind of coal mine coal bed drilling drawn out methane and annular air-pocket hole sealing device that injection hole sealing uses.
Background technology
In colliery mash gas extraction and injection hole sealing, the existing normal plug that uses is by simple cotton or plank, and steel plate is formed, and shutoff all exists poorly sealed close when holing, be prone to spillage, runs into defectives such as can not delivering to assigned address when collapsing hole and other drilling accident.The consumption calculating that has seriously influenced the sealing of hole slurry like this is inconsistent with the practice of construction consumption, and the sealing of hole effect is undesirable, and extraction is not up to standard.Shutoff is not tight, and sealing of hole is unsuccessful, causes the waste of material, and the sealing of hole cost is higher, does not reach instructions for use.Bring bigger economic pressures to enterprise production.
Summary of the invention
The purpose of the utility model is the weak point that overcomes in the prior art, provides a kind of simple to operate, easy to use, the annular air-pocket hole sealing device that sealing of hole is effective.
For realizing above-mentioned purpose, the utility model annular air-pocket hole sealing device comprises the aerating device that is made up of gas-charging connection, force pipe, ball valve, pressure meter and inflator; Also comprise the sealing of hole plug; The sealing of hole plug comprises annular air-pocket, and the front end of annular air-pocket is provided with support ring, and the rear end of annular air-pocket is provided with half support ring of two fastenings; Be provided with gap between half support ring of two fastenings, opening position is provided with the valve that matches with gas-charging connection; Two-layer rubber layer inside and outside described annular air-pocket has; Described valve is provided with external screw thread.
Beneficial effect: use annular air-pocket inflation carrying out shutoff boring; Only needing an aerating device is that inflator or manual pump can be accomplished shutoff boring; Solved existing plug, send not in place, the problem that shutoff is poorly sealed; Air bag plug external diameter and bore diameter gap are very big before the inflation, can smooth and easyly deliver to assigned address; After the inflation, plug annular expands and forms two O type circles that vary in size, and tightly sturdyly on drill hole wall and extraction pipe outer wall, can not leak, and accomplishes shutoff, fills closely knitly during slip casting, do not have waste, and the drilling orifice plug can reclaim repeatedly utilization.
Description of drawings
Fig. 1 is a kind of annular air-pocket hole sealing device structural front view of the utility model.
Among the figure: 1-support ring, 2-annular air-pocket, 3-half support ring, 4-valve, 5-gas-charging connection, 6-force pipe, 7-ball valve, 8-pressure meter, 9-inflator.
The specific embodiment
Below in conjunction with the embodiment in the accompanying drawing the utility model is done further to describe:
As shown in the figure, the annular air-pocket hole sealing device of the utility model comprises by gas-charging connection 5; The aerating device that force pipe 6, ball valve 7, pressure meter 8 and inflator 9 constitute also comprises the sealing of hole plug, and the sealing of hole plug comprises annular air-pocket 2; Two-layer rubber layer inside and outside described annular air-pocket 2 has; The front end of annular air-pocket 2 is provided with support ring 1, and the rear end of annular air-pocket 2 is provided with between half support ring 3 of 3, two fastenings of half support ring of two fastenings and is provided with gap; Opening position is provided with the valve 4 that matches with gas-charging connection 5, and valve 4 is provided with external screw thread.
The course of work: the gas that inflator 9 provides certain pressure gets in the annular air-pockets 2 through pressure meter 8 and ball valve 7 successively, and can read the pressure the annular air-pocket 2 this moment from pressure meter 8, make annular air-pocket 2 take place at short notice inside and outside two-layer expansion; Annular expands and forms two O type circles that vary in size; Tightly sturdyly on drill hole wall and extraction pipe outer wall, can not leak, accomplish shutoff, fill closely knit during slip casting; Do not have waste, and the drilling orifice plug can reclaim repeatedly utilization.
