Abstract
The invention discloses a drill pipe air operated slip capable of clearing impurities. The air operated slip comprises a great square slip with a V-shaped slot in the middle, a slip body of which the bottom is adhered and inserted into the V-shaped slot of the great square slip, and a mud-scraping disk. The slip body is hollow; a slip tooth is installed on the inner chamber of the slip body; guide rods are respectively in the vertical direction at the two sides of the slip body; a strengthening ring is arranged at the bottom of the V-shaped slot of the great square slip; the adhesion part of the top of the great square slip and the slip body is provided with a cylinder; the top of the great square slip is provided with a gas circuit mechanism which is adjacent to the cylinder; the mud-scraping disk is arranged at the top of the slip body and installed on a base; and the two ends of the base are fixed on the corresponding slip body by a bolt. By adopting the above principles, the slip improves the assembly structure of the slip body and the slip tooth, and improves the bearing ability of the slip body; mud and the like are prevented from falling in the slip; and the slip can work well.
Description
Technical field
The present invention relates to field of oil drilling, be specifically related to the drill pipe pneumatic slip can clearing up foreign material.
Background technology
Drilling slip is used for drilling rod or sleeve pipe to clamp the rig tool be held on rotating disk in oil drilling construction.The instrument holding drilling rod in existing oil, natural gas operations mainly contains manual drill pipe slip, multiple-piece structure, and volume is large, and weight is large, and labour intensity is large, inefficiency and safety is not high; Air spider can realize the automatic lifting of slips body, but this device volume is huge, and is arranged on above rotating disk, makes complete machine height distance plane of rotor disc higher, and using to hydraulic tongs makes troubles.Drilling slip comprises drill pipe slip, drill collar slips and casing slip three kinds, can be divided into portable slips, semi-automatic slips and full-automatic slips according to the difference of mode of operation.Full-automatic drill pipe pneumatic slip, as the one of automatic power slips, has the application of small lot at situ of drilling well, have that labour intensity is little, the operating efficiency that makes a trip is high, the feature of well head safe good operation performance.But because current product seriation and standardization level are inadequate, there is following defect in air operated slips of today: slips insufficient strength, the supporting capacity of slips is poor, easy damage drilling rod and when working out of doors, exterior earth is easily fallen in slips, affects normal operating.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, there is provided the drill pipe pneumatic slip can clearing up foreign material, this slips improves the assembly structure of slips body and slip insert, improves the supporting capacity of slips body, and avoid earth etc. to fall in slips, ensure that slips can better work.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: the drill pipe pneumatic slip can clearing up foreign material, comprise that centre has the large quadrel of V-type groove, slips body in large quadrel V-type groove is inserted in bottom laminating and mud scraping disc, described slips body hollow, the inner chamber of slips body is provided with slip insert, the vertical direction of slips body both sides all arranges guide peg; On described large quadrel, the bottom of V-type groove arranges centering ring, and also arrange cylinder in the joint place of large quadrel top and slips body, also arrange gas circuit mechanism at large quadrel top, gas circuit mechanism is adjacent with cylinder; The top of described slips body also arranges mud scraping disc, and mud scraping disc is arranged on base, and the two ends of base are bolted on corresponding slips body.
Slips body is set to insert in the V-type groove of large quadrel, after in the cavity that drilling rod inserts large quadrel and the formation of slips body, increases the contact area of slip insert and drilling rod, improves the supporting capacity of slips, also do not damage drilling rod.Slips body wherein and slip insert are structure as a whole, and guide peg extends in the large quadrel of insertion, thus improve the supporting capacity of slips.Carry out in outdoor because drill-well operation is many, outside silt etc. is easily blocked in the head of slips, make drilling rod cannot enter the cavity of slips body and the formation of large quadrel, and mud scraping disc is also set at the top of slips body, unnecessary earth can be wiped off, avoid earth to fall into, ensure the normal work of slips.
Further, described mud scraping disc can cover the top of whole slips body and be provided with the through hole mated with drilling rod in the centre of mud scraping disc.When mud scraping disc breaks down, adopt this kind of connected mode, replacing mud scraping disc for convenience detach.
Further, insert in large quadrel bottom described guide peg.It is firm that the large quadrel of further guarantee is connected with slips body.
Further, above described large quadrel V-type groove inwall, also horizontal supporting plate is set.
Further, the thickness of described large quadrel is the twice of slips body thickness.Increase the supporting capacity bottom slips.
Further, each slip insert is sawtooth trapezoidal shape.While enlarge active surface, the damage to drilling rod can be reduced.
Compared with prior art, the invention has the beneficial effects as follows:
1, the present invention is optimized slips body structure, respectively from thickening thickness, stressed on slips body of dispersion slip insert of slips body bottom and adopting the centering means such as the slip insert of special thickening to improve the stressed shape of slips body, the stress reducing slips body bottom is concentrated, dispersive stress is to the different parts of slips body, improve the weight capacity of slips body, also can not cause damage to drilling rod simultaneously.
2, carry out in outdoor because drill-well operation is many, outside silt etc. is easily blocked in the head of slips, make drilling rod cannot enter the cavity of slips body and the formation of large quadrel, at the top of slips body, also mud scraping disc is set, unnecessary earth can be wiped off, avoid earth to fall into, ensure the normal work of slips.

Fig. 1 is sectional view of the present invention.
In figure, Reference numeral is expressed as:
1, large quadrel; 2, slips body; 3, cylinder; 4, gas circuit mechanism; 5, slip insert; 6, mud scraping disc; 7, guide peg; 8, centering ring.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further elaborated, and embodiments of the invention are not limited thereto.
Embodiment 1:
As shown in Figure 1, for drilling rod has inserted in the cavity that large quadrel and slips body formed, the present invention includes that centre has the large quadrel 1 of V-type groove, slips body 2 in large quadrel 1V type groove is inserted in bottom laminating and mud scraping disc 6, described slips body 2 hollow, the inner chamber of slips body 2 is provided with slip insert 3, the vertical direction of slips body 2 both sides all arranges guide peg 6; On described large quadrel 1, the bottom of V-type groove arranges centering ring 7, also arranges cylinder 3 in the joint place of large quadrel (1) top and slips body 2, and also arrange gas circuit mechanism 4 at large quadrel 1 top, gas circuit mechanism 4 is adjacent with cylinder 3; The top of described slips body 2 also arranges mud scraping disc 6, and mud scraping disc 6 is arranged on base, and the two ends of base are bolted on corresponding slips body 2.
