Abstract
The utility model relates to an eccentric double U-shaped sucker rod oil stripper for stripping the crude oil off the outer wall of a sucker rod when lifting the sucker rod from an oil well. The sucker oil stripper comprises an upper cover, a double U-shaped oil-stripping rubber layer, a tension spring and other parts. Before lifting the sucker rod from the oil well, the regulating screws at both ends are adjusted to the maximum positions; the polished rod passes through the center of the eccentric double U-shaped sucker oil stripper to allow the small U-shaped part of the U-shaped rubber layer to be closely attached to the outer wall of the sucker rod; and then the regulating screws at both ends are tightened to mount the connecting short piece to the oil pipe coupler or the well-head oil pipe suspender. When lifting the sucker rod, the eccentric double U-shaped sucker rod oil stripper can clean the crude oil off the outer wall of the sucker rod to allow the crude oil to flow out through oil drainage holes. Therefore, the eccentric double U-shaped sucker rod oil stripper has the advantages of mechanized and automatic oil-cleaning function, less pollution of the crude oil to the well site during the lifting of the sucker rod and reduced labor intensity of the worker.
Description
Technical field
The utility model purpose provides when playing sucker rod in a kind of workover treatment, removes the sucker rod oil wiper that its outer wall adheres to crude oil.
Background technology
In the oil well operation process, rise when taking out bar, crude oil pollution well head, well site that the sucker rod appearance adheres to often occur, operating personnel have also been caused potential safety hazard; Meet when blowing weather, stick to the crude oil of sucker rod appearance, got everywhere by wind and be scattered, that gives the well site has caused very big pollution on every side, to realizing green well site, has also increased very big difficulty.Therefore, use the sucker rod oil wiper to become a kind of indispensable frizing instrument.
At present, mainly there are following three problems in the sucker rod oil wiper that uses on the scene:
The first, two frizing rubber horizontal positioned, after the wearing and tearing of frizing rubber internal diameter, internal diameter enlarges, and can't contact with the sucker rod body, can not continue frizing;
The second, after the wearing and tearing of frizing rubber internal diameter, there is not automatic regulatory function;
Three, owing to do not have automatic regulatory function after the wearing and tearing of frizing rubber, it is frequent therefore to change rubber, big to frizing rubber quantitative requirement;
Summary of the invention
The eccentric double-U-shaped sucker rod oil wiper of the utility model, technical problem to be solved is: after frizing rubber is worn, compensate this problem automatically.Clamping cylinder is equipped with in both sides at this utility model body, and an end of clamping cylinder is equipped with the adjusting plug, regulates elastic force size the regulating action of the spinning in and out of plug to spring; Holddown spring in the clamping cylinder contacts with double-U-shaped frizing rubber.Two blocks of double-U-shaped frizing rubber of off-centre, adopt and to intersect displacement structure up and down, place this structure owing to adopted frizing rubber to intersect up and down, after frizing rubber is worn, because the effect of holddown spring elastic force, the frizing rubber after the wearing and tearing can contact with sucker rod all the time, and the elastic force by holddown spring reaches the compensation frizing rubber purpose of wearing and tearing, simultaneously, utilized frizing rubber to greatest extent.
The use of this instrument realized mechanical automatic edible vegetable oil, and crude oil is to the pollution in well site when having significantly reduced sucker rod.This product is small and exquisite, simple, dismounting, easy for installation.Frizing rubber has adopted the rubber wear-resisting, that elasticity is big, long service life.
Description of drawings
Accompanying drawing is a sectional view of the present utility model.
1-loam cake among the figure, the 2-body, the eccentric double-U-shaped frizing rubber of 3-, the 4-clamping cylinder, 5-regulates plug, the 6-holddown spring, 7-connects pipe nipple, 8-lower cover, 9-draining hole.
The specific embodiment
The utility model is made up of loam cake 1, body 2, eccentric double-U-shaped frizing rubber 3 etc., two blocks of double-U-shaped frizing rubber 3 of off-centre are housed in the body 2, the both sides of body 2 are welded with clamping cylinder 4 respectively, holddown spring 6 is housed in the clamping cylinder 4, one end of holddown spring 6 acts on regulates on the plug 5, and the other end acts on the eccentric double-U-shaped frizing rubber 3.
Eccentric double-U-shaped frizing rubber 3 has adopted double-H groove weld eccentric type structure, the size bottom circularity of its little U type, and corresponding with sucker rod body diameter, the extended distance of large U type is corresponding with the rod collar diameter.
The large U type of eccentric double-U-shaped frizing rubber 3 and the center of circle that little U type all departs from rubber, when having guaranteed that box cupling is by rubber when playing sucker rod, two blocks of rubber still can keep chi structure up and down.
The double-U-shaped frizing rubber 3 of intrinsic two off-centre takes to be staggeredly placed up and down structure, can guarantee in the process that plays sucker rod, even there are wearing and tearing at the little U type place of eccentric double-U-shaped frizing rubber 3, under the effect of holddown spring 6, the little U type place that also can realize eccentric double-U-shaped frizing rubber 3 contacts with the outer wall of sucker rod all the time, does not influence the frizing effect.
Clamping cylinder 4 is equipped with in the both sides of body 2, and an end of clamping cylinder 4 is equipped with regulates plug 5, regulates elastic force size the regulating action of the spinning in and out of plug 5 to spring.
The other end of holddown spring 6 acts on the eccentric double-U-shaped frizing rubber 3, owing to the effect of spring force, can make the little U type place of eccentric double-U-shaped frizing rubber 3, is close to all the time on the outer wall of sucker rod body.
During the oil well operation, before playing polished rod, earlier the adjusting plug at two ends is adjusted to maximum position, polished rod is passed from the centre of the double-U-shaped sucker rod oil wiper of off-centre, make the little U type place of U type rubber be close to the sucker rod outer wall, tighten the adjusting plug at two ends then, will connect pipe nipple and be installed on tubing coupling or the well head tubing hanger.
When playing sucker rod, frizing rubber just can be removed the crude oil that the sucker rod outer wall adheres to, and crude oil goes out from the draining orifice flow, reaches the frizing purpose.
