Abstract
Aiming to solve the problems that the conventional hole sealing device is inconvenient to operate and cannot seal a hole quickly, the invention discloses an instant hole sealing device, which includes an inner pipe and an outer pipe, wherein the outer pipe includes a front end pipe, a rear end pipe and a middle plugging area; the plugging area includes a pipy nylon net connected with the front end pipe and the rear end pipe of the outer pipe; a liquid bag is sleeved on the outer side of the nylon net and consists of an A bag filled with A liquid and a B bag filled with B liquid; the inner pipe is mounted inside the outer pipe in a sleeving manner; a suction flange is fixed with the front end of the inner pipe; an air inlet is fixed at the tail end of the inner pipe; and a barb contacted with the liquid bag at the plugging area is arranged on the outer wall at the middle part of the inner pipe. According to the invention, relative displacement occurs between the outer pipe and the inner pipe; the barb on the inner pipe punctures the liquid bag in the plugging area, so that A liquid and B liquid perform chemical reaction and expand, and plugging is realized; the device can be used for plugging without any pressurizing equipment, is simple and convenient to operate, can seal a hole instantly, and controls the methane gas overrun timely.
Description
Technical field
The present invention relates to a kind of mine gas tapping equipment, specifically is the hole sealing device in a kind of gas discharge in mine hole.
Background technology
Chang Yin cuts off the gas hole and causes the fluctuation of regional area gas bearing capacity unusual in the tunneling process; Be under the situation of slotted hole particularly in extraction boring; The accident of cutting off the gas hole is more frequent; In the shortest time, connect to take out and cut off the gas hole, for preventing gas exceeding limit, it is very crucial ensuring safety in production.
The sealing of hole in known gas discharge in mine hole is that releasing pipe is inserted in the gas discharge in mine hole; Then with cement mortar or Polyurethane with shutoff around the pipe, the shortcoming of this method is operation inconvenience, the sealing of hole weak effect; Can not realize quickly and effectively that sealing of hole, releasing pipe are unfavorable for reclaiming.
Most rapid hole sealing devices need utilize external pressurized, inject other meson realization sealing of hole purpose on the existing market; Problems such as working programme is loaded down with trivial details, operating equipment is many, practical operation inconvenience to causing certain potential safety hazard in the working region, can not very easily cause special circumstances such as the working region gas emission is big timely with gas control.
Summary of the invention
The objective of the invention is to solve operation inconvenience that existing hole sealing device exists, the problem of sealing of hole rapidly, a kind of rapid hole sealing device is provided.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:
A kind of rapid hole sealing device, pipe and outer tube in comprising, outer tube is made up of the shutoff district at front tube, rear end pipe and middle part; The shutoff district comprises the tubulose nylon wire that is connected with outer tube front tube and rear end pipe, and the nylon wire outside is with dress liquid bag, and dress liquid bag is made up of A bag that A liquid is housed and the B bag that B liquid is housed; The interior pipe box outer tube inside of packing into; In the front end of pipe be fixed with to connect and take out flange, interior pipe end is fixed with air inlet port, interior pipe middle part outer wall be provided with the shutoff district on the barb that contacts of dress liquid bag.
During use, at first connecing of interior pipe taken out flange and be connected with the gas drainage under suction arm, hole packer is inserted gas extraction hole to correct position, the rear end pipe of shutoff district and outer tube is all inner at gas extraction hole.Pin pipe in the outer tube front tube pulling with hand, make between outer tube and the interior pipe moving mutually displacement takes place, the barb on the interior pipe punctures the dress liquid bag in the shutoff district, and make A liquid and B liquid in the shutoff district, chemical reaction take place and expand, thus completion shutoff operation.
Compare with existing apparatus, rapid hole sealing device provided by the invention need not any pressurized equipment can accomplish the sealing of hole operation, simple, convenient, can accomplish sealing of hole rapidly, in time controls gas exceeding limit.
Description of drawings
Fig. 1 is the structural representation of rapid hole sealing device of the present invention.
Among the figure, pipe in the 1-, the 2-front tube, the 3-rear end pipe, the 4-nylon wire, 5-dress liquid bag, 6-connects and takes out flange, 7-air inlet port, 8-barb, 9-fixed block, 10-conical plug, 11-integral cast handle.
The specific embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is further specified.
A kind of rapid hole sealing device; Pipe 1 and outer tube in comprising, outer tube is made up of the shutoff district at front tube 2, rear end pipe 3 and middle part, and the shutoff district comprises the tubulose nylon wire 4 that is connected with outer tube front tube 2 and rear end pipe 3; Nylon wire 4 outsides are with dress liquid bag 5; Dress liquid bag 5 is made up of A bag that A liquid is housed and the B bag that B liquid is housed, and interior pipe 1 overlaps the outer tube inside of packing into, and interior pipe 1 front end is fixed with to connect takes out flange 6; In pipe 1 end be fixed with air inlet port 7, interior pipe 1 middle part outer wall be provided with the shutoff district on the barb 8 that contacts of dress liquid bag 5.
Inner and outer pipe adopts the bushing type project organization, and outer tube plays the effect of supporting with shutoff, and interior pipe 1 connects to be taken out.A, B liquid are sealing material polyurethane, isocyanates and polyethers, chemical reaction post-foaming, volume expansion.Separated by one deck barrier film in the middle of A bag and the B bag, in the expansion fixed operation, the barb 8 in the shutoff district on the pipe 1 will be adorned the liquid bag and scratch, and A, B liquid mix, and chemically reactive attaches with rib around in shutoff, being expanded to fully, realizes shutoff.The effect of nylon wire is after the polyurethane soup mixes, and some soup oozes down from nylon wire, can be in the gap between sealed outer pipe after the expansion and content.Air inlet port 7 is provided with filtering holes.
Outer tube back-end pipe 3 connecting tube of end shape fixed blocks 9, fixed block 9 comprises flexible pipe, and the flexible pipe surface is provided with hangnail, on the tube wall of the rear end of interior pipe 1, is provided with conical plug 10, and the small end face of conical plug 10 contacts with fixed block, and large end face and water inlet are fixed.
Because the pressure in the extraction hole is bigger, under the effect of in the extraction hole, pressing, the sawtooth of fixed block 9 outer walls is set one's teeth on edge and is contacted with extraction hole rib, produces resistance.When drawing outside the interior pipe 1, conical plug 10 moves simultaneously, and the fixed block on the outer tube back-end pipe 9 is strutted, and the sawtooth of fixed block 9 outer walls is set one's teeth on edge and the rib CONTACT WITH FRICTION, produces resistance, thereby it is fixing to realize expanding.
Mouth of pipe place in the outer tube front tube is provided with integral cast handle 11, is used in external, managing 1 o'clock, supports outer tube, and pipe was taken outer tube out of in 1 o'clock in preventing to connect.
