2. correcting gripping mechanism under oil pipe according to claim 1, it is characterised in that: the left jaw (3) and right jaw (4) the opposite place in inside is respectively equipped with concave-convex card slot (7).

3. correcting gripping mechanism under oil pipe according to claim 1 or 2, it is characterised in that: the left hydraulic cylinder (5) and the right side Hydraulic cylinder (6) passes through synchronously control.

Technical field

The present invention relates to correcting gripping mechanisms under a kind of oil pipe, belong to petroleum well workover machinery technical field.

Background technique

When lower oil pipe, oil pipe by manipulator when being grabbed to well head top position, due to the rigidity and environment of oil pipe itself Etc. factors, cause crawl oil pipe cannot be effectively aligned with well mouth oil pipe, so oil pipe below need a guide device, correcting Device plays the role of correcting deviation in workover treatment.

Summary of the invention

The technical problem to be solved by the present invention is in view of the defects existing in the prior art, provide one kind.

In order to solve this technical problem, the present invention provides correcting gripping mechanisms under a kind of oil pipe, including left support, right branch Frame, left jaw, right jaw, left hydraulic cylinder and right hydraulic cylinder, the left jaw and right jaw are logical with left support and right support respectively Cross stud connection；It is opposite on the inside of the left jaw and right jaw, hinged with left hydraulic cylinder and right hydraulic cylinder respectively, the left liquid in outside Cylinder pressure and the right hydraulic cylinder other end are separately fixed on left support and right support；Left hydraulic cylinder and right hydraulic cylinder respectively drive left pincers Mouth, right jaw are opposite to be swung, realizes the movement for clamping oil pipe.

Opposite place is respectively equipped with concave-convex card slot on the inside of the left jaw and right jaw.

The left hydraulic cylinder and right hydraulic cylinder pass through synchronously control.

The utility model has the advantages that the present invention is to cooperate the pipe wrench platform of brand new and design, the mobile model of new pipe wrench platform pipe wrench It is trapped among in front of oil pipe, such guide device is located between well head and large arm, in order to which rail concedes mobile space, guide device It is designed to split type mechanism, influences the movement of manipulator and pipe wrench cooperation by correcting clamp.

Specific embodiment

The present invention will now be described in detail with reference to the accompanying drawings and examples.

Fig. 1 show the structural schematic diagram of opening state of the present invention.

Fig. 1 a show the structural representation front view of opening state of the present invention.

Fig. 2 show the structural schematic diagram of clamped condition of the present invention.

Fig. 2 a show the structural representation front view of clamped condition of the present invention.

The present invention provides correcting gripping mechanisms under a kind of oil pipe, including left support 1, right support 2, left jaw 3, right jaw 4.Left hydraulic cylinder 5 and right hydraulic cylinder 6, the left jaw 3 and right jaw 4 are connected with left support 1 and right support 2 by hinged shaft respectively It connects；The left jaw 3 and 4 inside of right jaw are opposite, and outside is hinged with left hydraulic cylinder 5 and right hydraulic cylinder 6 respectively, left hydraulic cylinder 5 and 6 other end of right hydraulic cylinder be separately fixed on left support 1 and right support 2；Left hydraulic cylinder 5 and right hydraulic cylinder 6 respectively drive a left side Jaw 3, right jaw 4 are opposite to be swung, realizes the movement for clamping oil pipe.

The opposite place of the left jaw 3 and 4 inside of right jaw is respectively equipped with concave-convex card slot 6.

The left hydraulic cylinder 5 and right hydraulic cylinder 6 pass through synchronously control.

The course of work of the invention:

Lower oil pipe: correcting clamp separated position simultaneously rises, and manipulator crawl oil pipe is moved to pithead position, correcting clamp folder Tightly, correcting clamp falls to oil pipe and docks with well head box cupling, and correcting clamp unclamps, and detains on pipe wrench, repeats the above movement.

Play oil pipe: correcting clamp separated position simultaneously declines, and pipe wrench shackle finishes, and correcting clamp clamps top oil pipe and develops simultaneously It rises, manipulator grabs oil pipe, and correcting clamp unclamps, and repeats the above movement.

Compared with prior art, the present invention can be realized Quick-clamped, and firm grip, clamp with conveying function more Add convenient and efficient, reduce the deviation of oil pipe, hydraulic pipe wrench and well head point-blank, improves oil pipe to the essence of its well head Degree, reduces the shock to oil pipe, improves the service life of oil pipe, improve work efficiency.The present invention have structure it is simple, Open it is high-efficient, save labour, the advantages that stability is high.

The embodiment above of the present invention, is merely illustrative, be not it is only, it is all within the scope of the present invention or it is equivalent this Change in the range of invention is surrounded by the present invention.
