Abstract
The utility model relates to an adjustable deviation prevention polished rod eye of an oil extractor, which is provided with a bottom beam. The bottom beam is provided with a clamping seat for a testing instrument; a polished rod of the oil extractor penetrates through the bottom beam and a central through hole in the clamping seat for the testing instrument to be fixedly connected with a polished rod clamp piece; and two end positions of the bottom beam are provided with suspension rope deviation prevention adjusting components. The polished rod eye has the functions of automatically adjusting the deviation of the polished rod eye and manually adjusting the levelness of the polished rod eye, so that the polished rod eye stays in good normal working state all the time, and simultaneously two suspension ropes have uniform stress and can prevent the polished rod from being abraded by the polished rod eye, thereby prolonging the service lives of the suspension ropes and the polished rod, reliably realizing the normal running of the oil extractor, improving the production efficiency and reducing the labor intensity.
Description
Technical field
The utility model belongs to pumping unit attachment technique field, oil field, is a kind of oil pumper inclined to one side polished rod eye of can relieving a garrison.
Background technology
In known oil pumper production technology, normally the polished rod eye with pumping unit horsehead connects polished rod, blocks polished rod with the polished rod clamp, and seat drives polished rod by oil pumper and pumps, the production of realization oil well on polished rod eye.In service at oil pumper often because the variation of polished rod stressing conditions, outstanding rope and the disconnected of polished rod occur and take off, its main cause is because of the horizontal tilt of polished rod eye and radially reverses and cause, because polished rod eye is not just, on polished rod, grind groove, cause polished rod to concentrate and disconnected taking off at fray stress; Secondly,, cause two outstanding rope unbalance stress, cause disconnected taking off because of a relatively short outstanding rope is stressed greatly when horizontal tilt appears in polished rod eye.When finding the polished rod eye horizontal tilt, generally need stop well and regulate, influence the time rate of oil well production, labour intensity is also bigger, and polished rod eye can only carry out horizontal tuningout, then can't adjust for the problem of polished rod eye front and back deflection.
The utility model content
It is easy to adjust quick that the purpose of this utility model provides a kind of outstanding rope length, and can realize the automatic adjustment of outstanding rope mechanism deflection, guarantees oil pumper that oil pumper normally the moves inclined to one side polished rod eye of can relieving a garrison.
Realize that the technical scheme that the purpose of this utility model is taked is: this polished rod eye has a bottom girder, be equipped with the tester deck on it, the polished rod of oil pumper passes the central through hole that is provided with on bottom girder and the tester deck fixedlys connected with the polished rod fastener, and the two-end part of bottom girder is equipped with the anti-offset joint of outstanding rope assembly.
The anti-offset joint of described outstanding rope assembly is made up of suspension rod, outstanding rope regulating sleeve, outstanding rope and wire clips head, wherein, the bottom of suspension rod is installed on the bottom girder, and locate by locking nut, top is connected with outstanding rope regulating sleeve by screw thread, outstanding rope regulating sleeve is a flower basket structure, and its top is provided with the T shape step through hole that cooperates with the wire clips head, and all sides have the open slot that is used to clamp the wire clips head.
The oil pumper of making according to the such scheme inclined to one side polished rod eye of can relieving a garrison, have deflection of automatic adjustment polished rod eye and the manual function of adjusting the polished rod eye level, make polished rod eye be in good normal operating conditions all the time, two outstanding ropes are stressed evenly simultaneously, can prevent that polished rod from being worn and torn by polished rod eye, prolong the application life of outstanding rope and polished rod, realize the normal operation of oil pumper reliably, and can enhance productivity, reduce labor intensity, and project organization is reasonable, and is easy to install.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, the oil pumper of the present utility model inclined to one side polished rod eye of can relieving a garrison, comprise bottom girder 1, tester deck 2, polished rod fastener 3 and the anti-offset joint of outstanding rope assembly composition, wherein, tester deck 2 is sat and is put on bottom girder 1, and the polished rod 4 of oil pumper passes the central through hole that is provided with on bottom girder 1 and the tester deck 2 fixedlys connected with polished rod fastener 3.The two-end part of bottom girder 1 is equipped with the anti-offset joint of outstanding rope assembly, and this assembly is made up of suspension rod 8, outstanding rope regulating sleeve 6, outstanding rope 5 and wire clips head 7, and wherein, the bottom of suspension rod 8 is installed on the bottom girder 1, and by locking nut 9 location.The top of suspension rod 8 is connected with outstanding rope regulating sleeve 6 by screw thread, and outstanding rope regulating sleeve 6 is a flower basket structure, and its top is provided with the T shape step through hole that cooperates with wire clips head 7, and all sides have and are used to clamp wire clips head open slot.
Operating principle: this can relieve a garrison inclined to one side polished rod eye in use, because polished rod 4 activities of oil pumper are installed in the central through hole of bottom girder 1 and tester deck 2, bear moment of torsion when excessive at polished rod 4, can and respectively install connector in central through hole relatively rotates, can avoid reversing of bottom girder 1 automatically thus, and prevent reversing relatively of two outstanding ropes 5.When two outstanding rope 5 different in size causing occurring, when bottom girder 1 occurred level tilts, only need to rotate the outstanding rope regulating sleeve 6 that is positioned at bottom girder 1 one ends, make suspension rod 8 flexible, can adjust the length unanimity of two outstanding ropes 5, guarantee the level of bottom girder 1, realized the stressed even of two outstanding ropes 5 and the purposes that polished rod 4 is not is not worn and torn by polished rod eye between two parties, prolonged the application life of outstanding rope 5 and polished rod 4 greatly.
