Detailed description of the invention
When considered in conjunction with the accompanying drawings, by referring to following detailed description, it can more completely more fully understand that this is practical new
Type and being easy learns many adjoint advantages, but attached drawing described herein is used to provide to the utility model into one
Step understands, constitutes a part of the utility model, and the illustrative embodiments and their description of the utility model are practical for explaining
It is novel, it does not constitute improper limits to the present invention, in which:
Fig. 1 is a kind of structural schematic diagram of high pressure pneumatics down-hole hammer specific drilling tool of the utility model.
Specific embodiment
Below in conjunction with attached drawing to the utility model, the technical scheme in the embodiment of the utility model is carried out clear, complete
Site preparation description.
Such as Fig. 1, a kind of high pressure pneumatics down-hole hammer specific drilling tool, including drill body 1, drill body 1 be equipped with pin thread and
Female thread, 3 hydrophthalmia of pin end is interior to be equipped with self seal oil union 4, and self-styled thimble 7, self-styled 7 end of thimble direction mother are equipped in self seal oil union 4
End of thread 2, self-styled thimble 7 pass through the flexible Self-enclosing for blocking or opening self seal oil union 4 of elastic mechanism.
During air compressor machine DTH drilling, put by self-styled thimble end towards oil drilling tools female thread extreme direction by self seal oil union
Enter into oil drilling tools pin end hydrophthalmia, self-styled thimble 7 carries out stretching motion by the effect of elastic construction and blocks or open certainly
The Self-enclosing of oil sealing nonyl 4, in the normal drilling process of air compressor machine down-hole hammer, high pressure compressed gas enters drilling tool water by kelly bar
Intraocularly, self-styled thimble is pushed elastic mechanism downlink by high pressure gas, Self-enclosing is opened, drilling tool smoothly supplies, and meets down-the-hole
The normal drilling of hammer.
When needing to connect drilling tool again after the single drilling of drilling tool, stopping elastic mechanism after supplying will be automatic after not having pressure
Rebound, drives self-styled thimble to close Self-enclosing, the high pressure gas in lower drilling tool hydrophthalmia just can not be sprayed onto well by Self-enclosing
Mouthful, have the function that carry out the operation that makes up a joint after seals high pressure gas, the drilling tool of the utility model just stop air compressor machine gas supply, have
The preventing from spraying outside high pressure gas of effect is hurted sb.'s feelings and the waste of high pressure gas, saves the time for normal drilling；It completely can be with alternate standard
Drilling tool check valve you, play the purpose of high pressure gas one-way trip in drilling tool water hole, this patent product can be repeated several times
It utilizes, service life is consistent with standard rig service life.
More preferably technical solution, elastic mechanism are spring 5, and self-styled thimble 7 is connected in self seal oil union 4 by spring 5, from
The needle 7 that binds pops up the Self-enclosing for blocking self seal oil union 4 under the action of spring 5, and the self-styled thimble 7 is by 1 hydrophthalmia of drill body
Interior high pressure gas pushes the Self-enclosing of compressed spring opening self seal oil union 4.
More preferably technical solution, self-styled thimble 7 are set in spring 5 from 5 one end of spring, and 5 other end of spring passes through spring
Seat 6 is set in self seal oil union 4.
More preferably technical solution, 8 welded seal of annular space between 3 hydrophthalmia inner circumferential of 4 end periphery of self seal oil union and pin end.
More preferably technical solution, drill body are 5 cun of oil drilling tools of API standard, and self seal oil union is 3 cun of self seal oil unions.
More preferably technical solution, for the pressure that can be born at 3 cun of self seal oil union Self-enclosings not less than 14MPA, sealing effect can
Obtain effective guarantee.
Embodiment 1:
Choose 5 cun of oil drilling tools of API standard (outer diameter: φ 127mm, internal diameter: φ 108.6mm, length 9.6m) and 3 cun of standard
High-pressure self-sealing oil nonyl (outer diameter φ 76.2mm, length 193.7mm, counterbore: φ 9.5mm, anti-pressure ability: 14MPa) two part structures
At.
3 cun of high-pressure self-sealing oil nonyls of standard are put into API standard towards 5 cun of oil drilling tools female thread extreme directions by self-styled thimble end
In 5 cun of oil drilling tools pin end hydrophthalmias, 3 cun of high-pressure self-sealing oil nonyls are sealed with 5 cun of oil drilling tools using electric welding, specific portion
