Abstract
The utility model discloses a large-tonnage casing elevator which comprises a body left hinge and a body right hinge. The rear end of the body left hinge and the rear end of the body right hinge are fixed together through a valve pin. A plunger latch is arranged at the front end of the body left hinge, and a slip is arranged in a conical hole defined by the body left hinge and the body right hinge. The slip is composed of four slip bodies, wherein the four slip bodies are arranged by being vertically and horizontally symmetric. Tooth boards are arranged in the four slip bodies respectively. The large-tonnage casing elevator is characterized in that a groove is formed in one side of the top of each slip body, and a protruding block matched with the corresponding groove is formed in the other side of the top of each slip body. The large-tonnage casing elevator has the advantages that synchronous moving of the slip bodies is achieved, a pipe pillar is stressed evenly and prevented from being clamped, the working efficiency and safety are improved, and labor intensity is reduced.
Description
Technical field
The utility model relates in a kind of petroleum gas drilling operation for holding, promote the special tool of the tubing strings such as oil pipe, drilling rod, sleeve pipe and electric submersible pump, especially be applicable to IJTBG and holding and promoting without FJL Casing, specifically, relate to a kind of large-tonnage casing elevator.
Background technology
Existing casing elevator is (while especially holding large-tonnage tubing string) when holding tubing string, and slips body often can not be synchronized with the movement, and makes the unbalance stress of tubing string, even can damage tubing string, affects follow-up use.And existing casing elevator is because the gap, rear end of main body left and right page is larger, in the process of clamping tubing string, is easy to block tubing string, affects normally carrying out of work, reduces operating efficiency.Therefore, need a kind of new technical scheme to solve above-mentioned technical problem.
Utility model content
The purpose of this utility model, is that a kind of large-tonnage casing elevator will be provided, and this casing elevator can overcome above-mentioned defect, realizes slips body and is synchronized with the movement, and guarantees that tubing string is stressed even, can prevent that tubing string from being blocked, and improves the security performance of operation.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of large-tonnage casing elevator, comprise main body verso and main body recto, the rear end of the left and right page of described main body is fixed together by valve pin, on the front end of described main body verso, be provided with lock bolt, in the conical bore that the left and right page of described main body surrounds, be provided with slips, described slips is comprised of symmetrically arranged four pages of slips bodies up and down, in every page of described slips body, dental lamina is all housed, in top one side of every page of described slips body, is provided with and on groove, opposite side, is provided with the projection matching with described groove.
On the top of two pages of slips bodies of close main body verso one side, be fixed with locating ring, described locating ring is fixed by screws on slips body.
The bottom of the left and right page of described main body is provided with guide strip.
The utility model has the advantages that: realize slips body and be synchronized with the movement, guarantee that tubing string is stressed even, can prevent that tubing string from being blocked, improved operating efficiency and safety, reduced labour intensity.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model structural representation.
Fig. 2 is that the B-B of Fig. 1 is to sectional drawing.
Fig. 3 is the structural representation of the utility model slips body.
Wherein: 1, main body verso, 2, main body recto, 3, valve pin, 4, lock bolt, 5, slips, 6, slips body, 7, dental lamina, 8, groove, 9, projection, 10, locating ring, 11, screw, 12, guide strip.
The specific embodiment
As shown in Figure 1, a kind of large-tonnage casing elevator, comprise main body verso 1 and main body recto 2, the rear end of the left and right page 1,2 of main body is fixed together by valve pin 3, on the front end of main body verso 1, be provided with lock bolt 4, in the left and right page of main body 1,2 conical bores that surround, be provided with slips 5, slips 5 is comprised of symmetrically arranged four pages of slips bodies 6 up and down, at the interior dental lamina 7 that is all equipped with of slips body 6 every page described.As shown in Figure 3, in the side of the top of slips body 6 every page described, be provided with and on groove 8, opposite side, be provided with the projection 9 matching with described groove, so when mounted, four pages of slips bodies 6 were fixed together by projection and coordinating of groove, four pages of slips bodies are synchronously fluctuated, the tubing string that guarantees clamping is stressed evenly, avoids tubing string to sustain damage.As shown in Figure 1, for fear of tubing string, be stuck in the gap of the left and right page of main body, on the top of two pages of slips bodies 6 near main body verso one side, fixed locating ring 10, locating ring 10 is fixed on slips body 6 by screw 11, in the slips body of changing different size, can change locating ring according to the size of tubing string like this, convenient to operation.As shown in Figure 2, for the ease of clamping and the lifting of tubing string, in the bottom of the left and right page 1,2 of main body, be provided with guide strip 12.
The utility model reasonable in design, flexible and convenient operation, is applicable to IJTBG, holding and promoting without tubing strings such as FJL Casing.
