Description
Technical field
The utility model relates to mine gas processing technology fields, and in particular to a kind of complete opening depth grafting floral tube.
Background technique
On to top plate drilling in the construction process, variation of lithological insufficient by deslagging, drilling rod self weight etc. many factors shadow
It rings, inclination angle can change a lot, track not instead of straight line, a similar parabolic curve.Core barrel hole sealing technology
Using pipe collar screwed connection, it is preferable to protect straight effect, but bending property is poor, it is difficult to change direction, can not accomplish that whole setting of casing is taken out
It adopts.It after working face pushes through the drilling, drills by stress rupture, single hole extraction amount is caused to reduce rapidly, action time is short, imitates
Fruit is poor.It is found after peephole, fragmented rock sleeve pipe reality tube portion in hole, forms clogging, a large amount of gas pressure relief
Without circulation passage, borehole failure is caused, to influence gas control effect, there are improvements for the prior art.
Utility model content
In order to solve the above technical problems, passing through several tube bodies the utility model proposes a kind of complete opening depth grafting floral tube
It is mating the pipeline that is consistent with drilling track is formed in hole, will drill in gas extraction, avoid generation gas explosion,
Guarantee staffs working in the mine, the safety of equipment.
In order to achieve the above objectives, the technical solution of the utility model is as follows: a kind of complete opening depth grafting floral tube, includes several
The mating tube body used, one end of the tube body are provided with tip, and the other end is provided with interface；The adjacent pipe
The mating connection by the tip and the interface of ontology；The tube body is along itself circumferentially-spaced offering presbyopia
Group, the presbyopia group are spaced apart along the length direction of the tube body.
By using above-mentioned technical proposal, in construction, drilling machine is drilled drilling in palisades, user by tube body successively
In insertion drilling, the tip of the tube body of first entrance has guiding role, avoids tube body and drilling that rigid contact occurs
And lead to occur bore inner generation local collapse in drilling；The tube body being located behind constantly pushes the pipe sheet being located in drilling
Body is that several tube bodies form complete opening depth grafting floral tube, if the tip of adjacent tube body and interface, which contact, makes main pipe sheet
Body can fit with the true form of drilling, to improve the extraction efficiency for the interior gas that drills；Pass through inserting for several tube bodies
The pipeline for cooperating and being formed in hole and being consistent with drilling track is connect, the extraction for the interior gas that will drill avoids that gas explosion occurs, guarantees
Staffs working in the mine, the safety of equipment.
The utility model is further arranged to: the internal bend of the interface towards tube body is formed with abutment ring.
By using above-mentioned technical proposal, on the one hand the abutment ring being arranged at interface can be improved when abutting with tip
Stability, the certain deformation space of another aspect abutment ring machine oil avoid excessive positioned at front tube body resistance and lead to pipe sheet
Body deformation.
The utility model is further arranged to: the tip includes that three pieces are inserted along what the tube body side was spaced apart
The angle of contact pin, the trapezoidal structure of insert-connecting plate, the insert-connecting plate and the tube body center line is that 8 °~12 ° inclinations are set
It sets.
The utility model is further arranged to: the spacing between the adjacent insert-connecting plate is 28~32mm.
The utility model is further arranged to: the length of the insert-connecting plate is 80~100mm.
The utility model is further arranged to: the presbyopia is directly 10mm.
In conclusion the utility model has the effect that
1, complete opening depth setting of casing purpose is realized, clogging of casing during extraction, holding watt are efficiently solved
This extraction channel is continuously unimpeded.
2, after using grafting floral tube complete opening mash gas extraction technology, single hole extraction combined amount is using 3.5 times of core barrel, greatly
It is big to reduce drilling hole amount, drilling efficiency is improved, drilling cost is reduced.
3, after using lower grafting floral tube technique, as long as working face pushes through the drilling, so that it may complete opening drainage holes internal channel and
Gas in wall-rock crack increases the extraction time.
4, using setting of casing technique inside drilling machine, safe operation performance is substantially increased.The single hole sealing of hole time is by original 8
Hour is reduced to 3 hours, substantially reduces the sealing of hole time, it is ensured that working face drilled during quickly propelling takes over progress.
5, core barrel in the market, is not able to satisfy the purpose of the efficient extraction of coal mine down-hole drilling, and grafting floral tube, not only completely
It is adapted on all kinds of to extraction borehole, and realizes high-efficiency and continuous extraction, it is 33.5 yuan/meter that processing cost is developed in self-control.
