Abstract
The utility model relates to a sucker rod straightening apparatus, in particular to a deformation preventing device of a sucker rod for oil extraction. The technical scheme includes that a sleeve is fixed onto a sucker rod which is arranged in an oil pipe, an upper nylon washer and a lower nylon washer are fixed to the upper end and the lower end of the sleeve respectively, and retaining rings are arranged at the ends of the upper nylon washer and the lower nylon washer respectively. The deformation preventing device of the sucker rod for oil extraction has the advantages that deformation of the sucker rod is avoided, and accordingly oil extraction efficiency of oil wells is improved; friction between the oil pipe and the sucker rod in movement is weakened by mounting the sleeve on the sucker rod, the sleeve is capable of effectively preventing deformation of the sucker rod, and the upper nylon washer and the lower nylon washer arranged on the upper end and the lower end of the sleeve have functions of fixing the sleeve and protecting the sucker rod; two semicircular sleeve bodies are convenient to demount, pressure buffering to the sucker rod can be reduced to effectively protect the sucker rod by the aid of an rubber sleeve in the sleeve bodies, and a sleeve hinge can be effectively fixed by a locking piece.
Description
Technical field
The utility model relates to a kind of sucker rod orthotics, particularly a kind of sucker rod oil production anti-deformation device.
Background technology
In oil field pumping well manufacturing process, sucker rod is up and down in oil pipe, due to the elastic deformation of sucker rod, bar and tubing wall easily produce friction, sucker rod is easily disconnected de-, sucker rod rubs with oil pipe in the process of moving up and down, and easily causes sucker rod distortion, thereby reduces the oil recovery efficiency of oil well.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of sucker rod oil production anti-deformation device is provided.
Its technical scheme is: comprise sucker rod, upper nylon cushion cover, lower nylon cushion cover, oil pipe, baffle ring, sleeve, oil pipe inside is provided with sucker rod, fixed muffle on described sucker rod, the two ends up and down of described sleeve are fixing upper nylon cushion cover and lower nylon cushion cover respectively, and described upper nylon cushion cover and the end of lower nylon cushion cover are respectively equipped with baffle ring; Described sleeve comprises two halves circular cylinder body, and the inside of described cylindrical shell is provided with rubber sleeve, and two halves circular cylinder body is by sleeve gemel connection, and described sleeve hinge is provided with lock dog.
The end of above-mentioned cylindrical shell is provided with dovetail groove, dovetail groove coordinate with upper nylon cushion cover, lower nylon cushion cover prevent sleeve rotate.
Above-mentioned nylon cushion puts and is provided with helical groove.
The beneficial effects of the utility model are: avoid sucker rod distortion; from improving the oil recovery efficiency of oil well; ensure that by installing sleeve on sucker rod sucker rod reduces the friction to oil pipe in motion process; sleeve can effectively prevent sucker rod distortion; upper nylon cushion cover, lower nylon cushion cover that sleeve is setting up and down; can play the object of fixed muffle and protection sucker rod; two halves circular cylinder body is for convenience detach; the rubber sleeve of inner barrel reduces the pressure buffer to sucker rod; effectively protection sucker rod, lock dog can effectively be realized the fixing of sleeve hinge.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structural representations of sleeve;
