Description
Technical field
The invention belongs to pneumatic down-hole hammer drilling applications, more particularly to a kind of pneumatic down-hole hammer drilling well is sealed with well mouth drill
Device.
Background technology
At present, ground rapid drilling has become a new technology of mine rescue, is got through for mine rescue
One " life channel ", the perfect rescue of especially Chilean mine disaster and the mine disaster of China Pingyi, it was demonstrated that the technology is quick, effect
Significantly.But the step for getting through simply mine rescue key of " life channel ", to rescue trapped personnel, it is also necessary to
" passway for escaping " is major diameter well（Hole diameter is not less than φ 650mm）Foundation.At present, the main technique of " passway for escaping " is just to follow
Ring pneumatic down-hole hammer drilling technology and reacting cycle pneumatic down-hole hammer drilling technology.
Both technologies is required for injecting pressure-air from ground by air compressor machine, so as to discharge well by shaft bottom landwaste is counter
Outside, air speed is needed to be at least up to 15m/s when being arranged because landwaste is counter, thus in drilling process, the anti-gas velocity that empties of well head is fast, mesh
Preceding wellhead sealing can't reach good sealing effectiveness and body and execution conditions to well head driller have severe shadow
Ring.
The content of the invention
The present invention seeks to propose a kind of pneumatic down-hole hammer drilling well to solve above-mentioned problems of the prior art
With well mouth drill sealer, adopted the technical scheme that to reach above-mentioned purpose：
A kind of pneumatic down-hole hammer drilling well well mouth drill sealer, including the left seal member of equal semicircular in shape housing and right sealing
One end of part, left seal member and right seal member is hinged, and the other end is bolted to connection and forms a circular knot
Structure；Left seal member is identical with right seal member structure, and the left seal member is by upper half plectane, lower half plectane, curved side
The semicircular shell with opening surface that plate encloses, semicircular latex sealing block, institute are embedded with left seal member
The shape and semicircular shell shape for stating latex sealing block match, and semicircular indentations are provided with the circle centre position of latex sealing block,
The rectangular indentation circumscribed with semicircular indentations is equipped with upper half plectane and lower half plectane, the semicircular indentations diameter is equal to
The long edge lengths of rectangular indentation；The rectangular indentation of left seal member and the rectangular indentation of right seal member surround one and are used for fixation side
The square breach of shape drilling rod.
Preferably, the planar section of latex sealing block protrudes the opening surface of left seal member.
Preferably, multiple perforation are provided with upper half plectane and lower half plectane, are furnished with perforation close for fixing latex
Seal the screw of block.
The advantageous effect of present invention is that：（1）Need constantly to add new sleeve pipe during drilling well, this is just
It is required that drilling rod sealer can be rapidly assembled and disassembled without influenceing drilling progress, reached using left seal member and right seal member
To the above-mentioned requirement being rapidly assembled and disassembled；（2）Latex sealing block inside left seal member and right seal member is to drilling rod
Further sealing is served, has reached better seal effect；Latex sealing block is reaching seal request using circumferential notch
Meanwhile also reduce cost of manufacture；（3）The planar section of latex sealing block protrudes the opening surface of left seal member, so as on a left side
Two latex sealing blocks are close to force together when seal member and right seal member close, and serve on the contact surface preferably close
Seal effect；（4）The screw being provided with upper half plectane and lower half plectane prevents latex sealing block close in left seal member and the right side
Seal in part and the generation of mobile inconsistent phenomenon occur.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of left seal member；
Fig. 3 is Fig. 2 right view.
Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of pneumatic down-hole hammer drilling well well mouth drill sealer, including equal semicircular in shape housing are left close
Part 10 and right seal member 5 are sealed, one end of left seal member 10 and right seal member 5 is hinged, as in left seal member 10
One end is welded with the first articulated elements 8, and the second articulated elements 6, the first articulated elements 8 and second are welded with one end of right seal member 5
Articulated elements 6 is be hinged by bearing pin 7, and the other end is fixedly connected by bolt 2 to form a circular configuration, in left seal member 10
With the nut 1 for fixing bolt 2 is welded with right seal member 5；Left seal member 10 is identical with the right structure of seal member 5.
As shown in Figures 2 and 3, now it is described by taking left seal member 10 as an example：The left seal member 10 be by upper half plectane 14, under
The semicircular shell with opening surface that semi-circular plate 15, arc side plate 13 enclose, embedded with half in left seal member 10
Circular latex sealing block 4, shape and the semicircular shell shape of the latex sealing block 4 match, in latex sealing block 4
Circle centre position is provided with semicircular indentations 3, and the rectangle circumscribed with semicircular indentations 3 is equipped with upper half plectane 14 and lower half plectane 15
Breach 9, the diameter of semicircular indentations 3 are equal to 9 long edge lengths of rectangular indentation；The rectangular indentation 9 of left seal member 10 and the right side are close
The rectangular indentation of envelope part 9 surrounds the square breach for being used to fix square kelly.
After left seal member 10 and right seal member 5 close, in order to prevent from producing larger gap at contact surface
Sealing effectiveness is influenceed, the planar section 12 of latex sealing block 4 protrudes the opening surface of left seal member 10.
In use, in order to prevent latex sealing block 4 from being moved in left seal member 10 and right seal member 5
Dislocation, is provided with multiple perforation on upper half plectane 14 and lower half plectane 15, is furnished with perforation and is used to fix latex sealing block 4
Screw 11.
In the use of the present invention, power kelly bar is connected on the drilling rod of pneumatic down-hole hammer, left sealing is then opened
Part 10 and right seal member 5 are enclosed on kelly bar, tighten bolt 2 and this sealer is tightly placed on kelly bar, now kelly bar position
In in square breach, under the elasticity tension effect of latex sealing block 4, latex sealing block 4 is tightly placed on drilling rod close so as to play
The effect of envelope, latex sealing block 4 why using circumferential notch mainly consider from seal request and cost of manufacture and
Selection, then this sealer influences worker and applied as kelly bar rotates so as to prevent landwaste from being sprayed close to kelly bar together
Work.
Finally it should be noted that：The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
The present invention is described in detail with reference to the foregoing embodiments, it will be understood by those within the art that：It still may be used
To be modified to the technical scheme described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic,
But these modification or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and
Scope.
