Technical field
The utility model relates to a kind of well head fast fixture that oil, gas drilling, completion and well workover played, descended drilling rod, drill collar and transfer sleeve pipe, oil pipe, special design is a kind of to be power with compressed air, can realize the air operated slips that clamps by quick replacing slips body to the tubing string of different size.
Background technology
The gripping mechanism that uses during oil, gas drilling and completion practice at present mostly is two elevators or single elevator adds portable slips, manually-operated, and labour intensity is big, inefficiency, and have potential safety hazard.The air operated slips that Chinese patent: 200320100403.X " multi-functional full-automatic drilling rod air operated slips ", 03221040.X " oil drill string air operated slips ", 200520068260.X " air operated slips " and 200520105076.X " combined type oil well operation air operated slips " five equilibrium have supplied wellbore construction to use indescribably, make that drilling rod rises, drill down operator is simple, improved automaticity, reduced working strength of workers, similar products like has abroad also been arranged.But above-mentioned several air operated slips all is that to promote supporting disk by cylinder up when pulling out of hole, and supporting disk pulling connecting rod drives that the slips body of hinge with it is up realizes getting out of the way the drill string room for promotion.Because the deadweight problem of slips body and connecting rod is subjected to downward gravity effect when up, be difficult to the maximization of implementation space, the collide with phenomenon of slip dog of drill string also inevitably takes place; Above-mentioned several air operated slips supporting disk all is directly to be connected with cylinder piston rod with guide peg by bolt, like this when clamping different size drill string need be changed different size slips body, need the bolt of dismounting many, and go up bolt contraposition trouble after changing the slips body, operation is mistaken, and is unfavorable for realizing quick replacing; Above-mentioned air operated slips with slip spider structure that big quadrel cooperates on be solid, weight is heavier, heaviness during operation is unfavorable for realizing Fast Installation.Based on the problems referred to above, these several air operated slips are not used widely.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of new multi-purpose tubing string air operated slips is provided.In order to achieve the above object, the utility model adopts following technical scheme:
A kind of multipurpose tubing string air operated slips, comprise slip spider, cylinder, the gas circuit seat, the slips body, scraper, connecting rod, supporting disk, guide peg, centering ring, dental lamina, two slip spiders are by connecting as a whole by hinge and bolt, cylinder is built in slip spider inside, gas circuit seat and supporting snap joint are fixed on the slip spider, the built-in gas channels that is integrated with links to each other with cylinder, the piston rod of cylinder and guide peg all are fixed on the supporting disk, centering ring is installed in the slip spider bottom, it is characterized in that, four groups of torsion springs have been set up between slips body and the connecting rod, torsion spring one end inserts in the slips body, the other end is fixed on the connecting rod, has set up the structure that supporting disk adds junction plate on the supporting disk.
Wherein, the structure that supporting disk adds junction plate is that guide peg links to each other with supporting disk by soket head cap screw, and junction plate links to each other with supporting disk by four bolts, and the slips body links to each other with junction plate by connecting rod, and the scraper hinge is on junction plate.Connected mode is hinge and is connected between connecting rod and junction plate and the slips body, and slip spider cylindrical middle part is the hollow body structure that adds reinforcing rib.
The beneficial effects of the utility model are: structure is light and handy, easy for installation, simple to operate, labor strength is low, can significantly improve, running speed.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the partial enlarged drawing of Fig. 1;
Fig. 3 is the sectional drawing of Fig. 1.
The specific embodiment
For the easier quilt of the utility model is understood, the utility model is done being described in more detail below in conjunction with the drawings and specific embodiments.
Consult Fig. 1, Fig. 2, Fig. 3, a kind of multipurpose tubing string air operated slips, comprise slip spider 1, cylinder 2, gas circuit seat 3, slips body 4, scraper 6, connecting rod 7, supporting disk 9, guide peg 10, centering ring 11, dental lamina 12, two slip spiders 1 are by connecting as a whole by hinge and bolt, cylinder 2 is built in slip spider 1 inside, gas circuit seat 3 and supporting snap joint are fixed on the slip spider 1, the built-in gas channels that is integrated with links to each other with cylinder 2, the piston rod of cylinder 2 and guide peg 10 all are fixed on the supporting disk 9, and centering ring 11 is installed in slip spider 1 bottom.
In addition, set up four groups of torsion springs 5 between slips body 4 and the connecting rod 7, torsion spring 5 one ends insert in the slips body 4, the other end is fixed on the connecting rod 7, have set up the structure that supporting disk 9 adds junction plate 8 on the supporting disk 9.Its structure is that guide peg 10 links to each other with supporting disk 9 by soket head cap screw, and junction plate 8 links to each other with supporting disk 9 by four bolts, and slips body 4 links to each other with junction plate 8 by connecting rod 7, on scraper 6 hinges and the junction plate 8.Connected mode is hinge and is connected between connecting rod 7 and junction plate 8 and the slips body 4.
