Description
Technical field
Drill pipe slip is the utility model is related to, specifically one kind is without dental impression drill pipe slip.
Background technology
Drill pipe slip is the indispensable mechanized shaftmouth instrument of oil and gas well drilling operation, and its function is that clamping is bored
Bar.Usually used SD series（SDS、SDML、SDXL）Drill pipe slip, it is by the leaf slips body of left, center, right three, dental lamina, hand handle etc.
Component composition, its conical degree of conical surface is 1：3.Slips body is filled the span of a man's arms drilling rod body during use, and drilling rod body is contacted with dental lamina, bored
In the presence of bar self gravitation, drilling rod produces pressure to dental lamina, and has descending trend, produces frictional force, while by caused by
Active force is delivered to slips body by dental lamina and is delivered to rotating disk benefit core again, and rotating disk mends core and prevents slips body from moving downward, and mends in-core cone
Face interacts with the external conical surface of slips, promotes three leaf slips bodies to mend core center to rotating disk and closes up, embraces drilling rod body, and then block
Tight drilling rod body.But there is the tooth that hardness is HRC58-62 on dental lamina surface, there is very big reaction force to drilling rod body, meeting exists
Drilling rod body surface produces deeper dental impression, big major injury drilling rod body, and serious meeting causes drilling rod to be scrapped, causes very big warp
Ji loss.
Utility model content
To solve the above problems, the utility model provide it is a kind of without dental impression drill pipe slip, while drilling rod is retained, no
Scar can be produced to the drill pipe coupling conical surface, will not more produce dental impression to drilling rod body.
The technical solution adopted in the utility model is：It is a kind of to mend core, hand handle, outside without dental impression drill pipe slip, including rotating disk
Wall is that three leaves of the conical surface positioned at left, center, right position and pass through company respectively without dental impression slips body, three leaf without dental impression slips body
Pin connects, and the rotating disk is mended core and is fitted tightly on lateral wall of three leaves without dental impression slips body, and the hand handle is separately positioned on
Top of three leaves without dental impression slips body, medial surface of three leaf without dental impression slips body are equipped with boss, connected on the boss
There is inclined-plane, the inclined-plane connects vertically arranged upper side, vertically arranged downside, the upper side are connected under the boss
With downside on same vertical plane, three leaf has cavity without dental impression slips body by connecting one inside of pin connection synthesis
Cone, the cavity that upper side of three leaves without dental impression slips body surrounds connects Gu vertical planes and coincide with boring bar, the sky that inclined-plane surrounds
Chamber coincide with the Zuan Gan Jie Gu conical surfaces, and the cavity that boss surrounds coincide with drilling rod body.
The angle on the inclined-plane and the angle of the Zuan Gan Jie Gu conical surfaces are 18 degree.
The beneficial effects of the utility model are：Because the conical surface is smooth in slips body, and the drill pipe coupling conical surface is also light
Sliding, although having active force each other and having relative motion trend, when drilling rod is retained, slips body cone will not be right
The drill pipe coupling conical surface produces scar, more will not produce dental impression to drilling rod body, can effectively eliminate wound of the slips to drilling rod body
Evil, cost is substantially reduced for oil and gas well drilling operation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is top view of the present utility model；
Wherein：1st, rotating disk mends core, and 11, rotating disk inner conical surface, 2, hand handle, 3, without dental impression slips body, 31, boss, 32, inclined-plane,
33rd, upper side, 34, downside, 35, without the external conical surface of dental impression slips, 36, without the conical surface in dental impression slips body, 4, connecting pin, 5, bore
Gan Jie Gu vertical planes, 6, the Zuan Gan Jie Gu conical surfaces, 7, drilling rod body.
Embodiment
In order to deepen to understanding of the present utility model, make below in conjunction with embodiment and accompanying drawing to of the present utility model into one
Step is described in detail, and the embodiment is only used for explaining the utility model, does not form the restriction to the scope of protection of the utility model.
As depicted in figs. 1 and 2, it is a kind of without dental impression drill pipe slip, including it is the conical surface that rotating disk, which mends core 1, hand handle 2, lateral wall,
Three leaves without dental impression slips body 3, three leaves are connected positioned at left, center, right position and by connecting pin 4 respectively without dental impression slips body 3, are turned
Disk is mended core 1 and is fitted tightly on lateral wall of three leaves without dental impression slips body 3, and hand handle 2 is separately positioned on three leaves without dental impression slips body 3
Top, medial surface of three leaves without dental impression slips body 3 be equipped with boss 31, the angled inclined-plane 32 for being 18 ° connected on boss 31,
Inclined-plane 32 connects vertically arranged upper side 33, the vertically arranged downside 34 of 31 times connections of boss, upper side 33 and downside
34 on same vertical plane, and three leaves connect one inside of synthesis without dental impression slips body 3 by connecting pin 4 has the circular cone of cavity
Body, cavity that upper side of three leaves without dental impression slips body 3 surrounds connect Gu vertical planes 5 with boring bar and coincide, the cavity that inclined-plane surrounds with
The Zuan Gan Jie Gu conical surfaces（Taper is similarly 18 °）6 coincide, and the cavity that boss surrounds coincide with drilling rod body 7.
The angle of lateral wall of three leaves without dental impression slips body is 9o27 ' 44 ".
Operation principle：Three leaves are filled the span of a man's arms the drill pipe coupling conical surface 6 without dental impression slips body 3 during use, in drilling rod self gravitation
Under effect, the drill pipe coupling conical surface 6 turns to mutually producing extruding force without the conical surface 36 in dental impression slips body and being delivered to this active force
Disk is mended on core 1, and rotating disk mends core 1 and prevents no dental impression slips body 3 from moving downward；Rotating disk inner conical surface 11 is to without the external conical surface of dental impression slips
35 interactions promote three leaves to close up without dental impression slips body 3 to center of turntable, embrace drill pipe coupling so as to clamping drill pipe coupling, by
The conical surface 36 is smooth in without dental impression slips body, and the drill pipe coupling conical surface 6 is also smooth, although having active force simultaneously each other
There is relative motion trend, but scar will not be produced to the drill pipe coupling conical surface 6 without the conical surface 36 in dental impression slips body, more will not be to drilling rod
Body 7 produces dental impression, but reaches the purpose for having retained drilling rod.
