Description
Technical field
The utility model relates to the technical fields of boring keeping straight device, more particularly, to a kind of stile.
Background technique
Currently, in drilling process, it is desirable that keep drilling track to construct in place according to design requirement, however, due to
The influence of the factors such as drilling device, construction technology, stratigraphic structure causes drilling to will appear different degrees of deflection, often occurs
Situations such as drilling is scrapped brings security risk for mining construction, influences construction efficiency.
Histogram method is protected in existing drilling to be realized by stile, and centralizer main body is fixed on drilling rod, with
Drilling rod coaxial rotating, when deflection occurs in drilling rod, centralizer main body is contacted with the wall of a borehole, is carried out by opposition to drilling rod
Righting.
Prior art among the above have the following deficiencies: the gap between the outer wall and the wall of a borehole of centralizer main body compared with
It is small, friction is easy to produce when drilling between the outer wall and the wall of a borehole of centralizer main body, and the mud generated that drills also be difficult to from
Gap location flows away, so as to cause drilling efficiency reduction.
Utility model content
In view of the deficienciess of the prior art, having the utility model lies in that providing a kind of stile and improving drilling
The effect of efficiency.
To achieve the above object, the utility model provides following technical solution: a kind of stile, including centralizer
Main body and the axial limitation ring for limiting the centralizer main body moving range, the centralizer main body includes for being set in drilling rod
On inner sleeve, housing, several braced wings between the inner sleeve and housing for contradicting for the wall of a borehole, the support
The both ends of the wing are fixedly connected with the inner sleeve and housing respectively.
By using above-mentioned technical proposal, inner sleeve is set on drilling rod by worker, then by axial limitation ring to righting
The position of device main body is defined；When skew does not occur for drilling rod, even if housing contacts generation friction with drilling, inner sleeve is also not easy
Hinder the drilling of drilling rod；When skew occurs when drilling rod is in drilling, drilling rod drives centralizer main body to move, centralizer main body
After movement, housing and drill hole inner wall are contradicted, to make centralizer main body be difficult to happen movement, to carry out by inner sleeve to drilling rod
Righting, while the space between braced wing enables mud to be discharged in time, to improve drilling efficiency.
The utility model is further arranged to: the axial direction limitation ring includes ring bodies, is threaded in the ring bodies
On positioning screw for being abutted with drilling rod.
By using above-mentioned technical proposal, ring bodies is set on drilling rod by worker, then screws positioning screw, makes to position
Screw rod is pushed against on drilling rod, so that the position to ring bodies is fixed, limits ring bodies to the position of centralizer main body
It is fixed.
The utility model is further arranged to: the outer diameter of the ring bodies is less than the internal diameter of the housing, the ring bodies
Internal diameter it is equal with the internal diameter of the inner sleeve.
By using above-mentioned technical proposal, ring bodies is not easy to be in contact with the wall of a borehole, while being also not easy to stop mud
Discharge, so that ring bodies is not easy to influence the normal work of drilling rod.
The utility model is further arranged to: width of the braced wing close to described inner sleeve one end is greater than the braced wing
Width close to housing one end.
By using above-mentioned technical proposal, braced wing more firm can be fixed between inner sleeve and housing, can be right
Housing is preferably supported, and housing is made to be not susceptible to deformation, and braced wing is made to be not easy to be detached from from interior set.
The utility model is further arranged to: the inner wall smooth setting of the inner sleeve.
By using above-mentioned technical proposal, smooth inner wall greatly reduces the frictional force between inner sleeve and drilling rod, In
When drilling rod is drilled, inner sleeve is not easy to hinder the rotation of drilling rod, so that drilling efficiency is not easily susceptible to influence.
The utility model is further arranged to: the outer diameter of the housing is less than the diameter of drilling.
By using above-mentioned technical proposal, housing and drilling between have certain gap so that housing be not easy with
It is in contact between drill hole inner wall, so that housing be made to be not easy to influence the drilling of drilling rod.
In conclusion the utility model has the following beneficial effects:
By setting centralizer main body and axial limitation ring, centralizer main body can be while not influencing rod boring
Righting is carried out when drilling rod deflection, axial limitation ring shows the moving range of centralizer main body, to carry out to drilling rod
Drilling efficiency is improved while timely righting.

Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
It referring to Figures 1 and 2, is a kind of stile disclosed by the utility model, including centralizer main body 1 and axial limit
Ring 2 processed.Centralizer main body 1 includes inner sleeve 11, housing 12 and several braced wings 13, and inner sleeve 11 and housing 12 are coaxially disposed, interior
The diameter of set 11 is less than the diameter of housing 12, and the outer diameter of housing 12 is less than the diameter of drilling, the inner wall smooth setting of inner sleeve 11.Branch
The both ends of the support wing 13 are fixedly connected with the inner wall of the outer wall of inner sleeve 11 and housing 12 respectively, and braced wing 13 is in along the axle center of inner sleeve 11
Circle distribution, braced wing 13 close to 12 one end of housing width be less than braced wing 13 close to 11 one end of inner sleeve width, adjacent two
Slurry channel 14 is formed between a braced wing 13.
Referring to Figure 1 and Figure 3, axial limitation ring 2 includes ring bodies 21 and positioning screw 22, and the outer diameter of ring bodies 21 is less than outer
The internal diameter of set 12, the internal diameter of ring bodies 21 is equal with the internal diameter of inner sleeve 11, offers several on the side outer wall of ring bodies 21
Threaded hole, threaded hole are circumferentially distributed along the axle center of ring bodies 21, and positioning screw 22 is threadedly coupled with threaded hole.
The implementation principle of the present embodiment are as follows: when being drilled, an axial limitation ring 2 is first set in brill by worker
On bar, then worker screws positioning screw 22 so that positioning screw 22 is pushed against on drilling rod, thus to the position of ring bodies 21 into
Row is fixed.Then centralizer main body 1 is set on drilling rod by worker, is bonded the inner wall of inner sleeve 11 with the outer wall of drilling rod.Then
An axial limitation ring 2 is arranged on drilling rod again, so that centralizer main body 1 is located between two axial limitation rings 2, is then screwed
The position of ring bodies 21 is fixed in positioning screw 22, so that the installation to stile is completed, two axial limitation rings 2
The moving range of centralizer main body 1 is defined at this time.When drilling rod is drilled, housing 12 is not easy to support with the wall of a borehole
Touching, even if housing 12 is contradicted with the wall of a borehole, since the contact surface between inner sleeve 11 and drilling rod is relatively smooth, inner sleeve 11 is not yet
The rotation of drilling rod is easily hindered, while the mud for the generation that drills is discharged from slurry channel 14.When drilling rod glances off, housing 12 with
The wall of a borehole is in contact, and housing 12, braced wing 13 and inner sleeve 11 hinder drilling rod to glance off, to carry out righting to drilling rod.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
