Abstract
The utility model provides a coal mine drilling blowout preventer, which includes an orifice sleeve, wherein a blowout preventing gate plate is fixedly connected with the top end of the orifice sleeve through a flange; and wheel discs are connected with the two ends of the blowout preventing gate plate through screw rods. The coal mine drilling blowout preventer has reasonable structure, small size, high intensity and strong safety and reliability; the two blowout preventing devices have better leak tightness and blowout preventing effect, can be used for preventing accidental blowout of water, methane gas or coal slacks; and the flange is used for connection, so that the operation is simple, the disassembly, assembly and maintenance are convenient, and the upper and the lower blowout preventing devices can be dismantled for individual use.
Description
Technical field
The utility model relates to the coal mining technical field, is specifically related to the device that a kind of coal mine down-hole drilling prevents water in the coal seam or gas ejection.
Background technology
In the process of coal mining,, influenced the normal exploitation in colliery, so elder generation's needs boring is carried out extraction to gas or water is discharged before coal mining because complicated geology contains a large amount of gas or water in the coal seam that has.When rig creeps under coal mine, when running into coal seam gassy, then invar this be inflammable and explosive gas, can to Safety of Coal Mine Production great threat be arranged from boring China and foreign countries spray; And when running into the big coal seam of water content, then have a large amount of water or coal slurry to spray from the aperture, worsened operating environment, and constructor's personal safety has also been had certain threat; When serious, when the water yield that sprays is big, limited by drainability, then can flood the tunnel, produce to the colliery and cause heavy economic losses.Water logging tunnel or work plane and the boring gas burst explosion accident that occurs now and then has had a strong impact on the safety problem of the normal exploitation in colliery.For fear of the generation of this type of accident, mostly blowout hookup is installed, outward so that under the situation of burst, spray through gases at high pressure or liquid in the blowout hookup control hole in aperture at drilling orifice.But the blowout hookup function of using at present is too simple, only around drilling rod, wraps up a circle rubber ring, and it is external to prevent that a part of water is sprayed onto the hole, in case but hydraulic pressure is excessive, the sealing of the rubber ring that then can conflict, and its blowout prevention effect is undesirable.
The utility model content
The utility model will solve above-mentioned deficiency exactly, and the blowout hookup that boring water outlet and gas ickings were gushed out when a kind of effective down-hole drilling construction was provided for the drilling construction personnel provide the operating environment of a safety, is guaranteed constructor's in the drilling operation safety.
In order to reach above-mentioned effect, the utility model provides a kind of colliery boring blowout hookup, comprises orifice sleeve, and said orifice sleeve top is connected with the blowout prevention flashboard through flange, and the two ends of said blowout prevention flashboard are connected with wheel disc through screw mandrel.
Said blowout prevention flashboard periphery is provided with sealing ring.
Said blowout prevention flashboard upper end is provided with the blowout prevention pad, and said blowout prevention pad top is provided with the gland of fastening blowout prevention pad.
In order further to strengthen the effect of blowout prevention, prevent a spot of gas or liquid through the flashboard ejection, the utility model also can be provided with weep pipe in said blowout prevention flashboard upper end, and said weep pipe and said blowout prevention flashboard are affixed through flange.
Said weep pipe upper end is provided with the blowout prevention pad, and said blowout prevention pad top is provided with the gland of fastening blowout prevention pad.
Said weep pipe be two symmetrically arranged, weep pipe is provided with valve.
The utility model boring blowout hookup is provided with twice blowout prevention facility up and down, first road be flashboard to the cassette blowout prevention, second road is the release blocking type.Geology characteristic according to the boring place is selected this twice blowout prevention facility for use, when fewer, can use one blowout prevention facility to get final product like water content in the coal seam or gas amount separately; If measure when bigger, then twice blowout prevention facility will use simultaneously, and the effect of blowout prevention is better.
When using, earlier the first road flashboard is fixed on through flange on the orifice sleeve of drilling orifice cassette blowout prevention facility, connect the last second road release blocking type blowout prevention facility through flange again.And when hole water outlet or gas are emerged; Through two ends wheel disc rotary screw, screw mandrel drives flashboard radially to central motion, makes the flashboard fluid sealant clamp drilling rod; Thereby annular space is realized sealing, the water yield of boring or an outstanding watt fusain bits amount are reduced to more than 99%.Have a spot of water or ickings to gush out, then got into the second road release and stopped in the blowout prevention facility, spray a spot of water or ickings and just flow away, and that the blowout prevention on its top is lined with gland is fastening, avoided air-flow etc. to release from here from weep pipe from flashboard and drilling rod gap.Basically can realize the blowout prevention technology requirement of holing through the twice blowout preventions, thereby guarantee bore operation environment and staff's safety.
The utility model compared with prior art has following benefit:
1, the utility model is rational in infrastructure, volume is little, intensity is high, security reliability is strong;
2, because of it connects through flange, it is simple to operate, dismounting is easy to maintenance, and the removable independent use of two cover blowout prevention facilities up and down;
3, two cover blowout prevention facilities, its sealing performance and blowout prevention are effective, the prominent spray of waterproof or gas ickings;
4, anticorrosive, oil resistivity, resistance to acids and bases are strong, long service life.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is embodiment one cross-sectional view;
Fig. 2 is embodiment two cross-sectional view;
Fig. 3 is embodiment three cross-sectional view;
Among the figure: 1-orifice sleeve, 2,2 '-flange, 3-screw mandrel, 4-wheel disc, 5-blowout prevention flashboard, 6-blowout prevention pad, 7-gland, 8-sealing ring, 9-weep pipe, 10 valves.
The specific embodiment
Embodiment one:
