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 the hole sealing device in a kind of gas discharge in mine hole.
Background technology
In tunneling process, Chang Yin cuts off gas hole and causes the fluctuation of regional area gas bearing capacity abnormal, particularly in the situation that extraction boring is slotted hole, the accident of cutting off gas hole is more frequent, within the shortest time, connect to take out and cut off gas hole, for preventing gas exceeding limit, ensure safety in production to be very crucial.
The sealing of hole in known gas discharge in mine hole is that releasing pipe is inserted in gas discharge in mine hole, then by cement mortar or Polyurethane by the shutoff of pipe surrounding, the shortcoming of this method is operation inconvenience, sealing of hole weak effect, can not realize quickly and effectively sealing of hole, releasing pipe is unfavorable for reclaiming.
On existing market, most rapid hole packers need to utilize external pressurized, inject other meson and realize sealing of hole object; The problems such as working programme is loaded down with trivial details, operating equipment is many, practical operation is inconvenient, to causing certain potential safety hazard in working region, can not, timely by gas control, very easily cause the special circumstances such as working region gas emission is large.
Summary of the invention
The object 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 packer is provided.
For achieving the above object, the technical solution used in the present invention is:
A kind of rapid hole packer, comprise inner and outer tubes, outer tube is made up of the shutoff district at front tube, rear end pipe and middle part, shutoff district comprises the tubulose nylon wire being connected with outer tube front tube and rear end pipe, and nylon wire outside cover has dress liquid bag, and dress liquid bag is made up of with the B bag that B liquid is housed the A bag that A liquid is housed, inner tube cover packs outer tube inside into, the front end of inner tube is fixed with to connect takes out flange, and inner tube end is fixed with air inlet port, and inner tube middle part outer wall is provided with the barb contacting with the dress liquid bag in shutoff district.
When use, first connecing of inner tube taken out to flange and be connected with gas drainage under suction arm, hole packer is inserted to gas extraction hole to correct position, the rear end pipe of shutoff district and outer tube is all in gas extraction hole inside.Pin outer tube front tube with hand and pull inner tube, make, between outer tube and inner tube, moving displacement mutually occurs, the barb in inner tube punctures the dress liquid bag in shutoff district, makes A liquid and B liquid, in shutoff district, chemical reaction occur and expands, thereby completing shutoff operation.
Compared with existing apparatus, rapid hole packer provided by the invention can complete sealing of hole operation without any pressurized equipment, simple, convenient, can complete rapidly sealing of hole, and control gas transfinites in time.
Accompanying drawing explanation
Fig. 1 is the structural representation of rapid hole packer of the present invention.
In figure, 1-inner tube, 2-front tube, 3-rear end pipe, 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 solutions according to the invention are described further.
A kind of rapid hole packer, comprise inner tube 1 and outer tube, outer tube is made up of the shutoff district at front tube 2, rear end pipe 3 and middle part, shutoff district comprises the tubulose nylon wire 4 being connected with outer tube front tube 2 and rear end pipe 3, nylon wire 4 outside covers have dress liquid bag 5, dress liquid bag 5 is made up of with the B bag that B liquid is housed the A bag that A liquid is housed, inner tube 1 cover packs outer tube inside into, inner tube 1 front end is fixed with to connect takes out flange 6, inner tube 1 end is fixed with air inlet port 7, and inner tube 1 middle part outer wall is provided with the barb 8 contacting with the dress liquid bag 5 in shutoff district.
Inner and outer pipe adopts bushing type project organization, and outer tube plays the effect of supporting with shutoff, and inner tube 1 connects takes out.A, B liquid are sealing material polyurethane, isocyanates and polyethers, chemical reaction post-foaming, volume expansion.In the middle of A bag and B bag, separated by one deck barrier film, in expansion fixed operation, the barb 8 in shutoff district inner tube 1 is scratched dress liquid bag, and A, B liquid mix, and chemically reactive is expanded to surrounding in shutoff and rib attaches completely, realizes shutoff.The effect of nylon wire is after polyurethane liquid mixes, some liquid from nylon wire oozes, can be after expansion gap between sealed outer pipe and inner tube.Air inlet port 7 is provided with filter bores.
Outer tube back-end pipe 3 connecting tube of end shape fixed blocks 9, fixed block 9 comprises flexible pipe, and flexible pipe surface is provided with hangnail, on the tube wall of the rear end of inner tube 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 extraction hole is larger, under the effect of pressing in extraction hole, the sawtooth of fixed block 9 outer walls is set one's teeth on edge and is contacted with extraction hole rib, produces resistance.In the time drawing outside inner tube 1, conical plug 10 moves simultaneously, and the fixed block on 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 rib CONTACT WITH FRICTION, produces resistance, fixes thereby realize expanding.
Mouth of pipe place in outer tube front tube arranges integral cast handle 11, for when the external inner tube 1, supports outer tube, while preventing from connecing inner tube 1, outer tube is taken out of.
