Abstract
The utility model provides a prevent a mao pigtail back twist polished rod eye, includes: hair pigtail, hanging wall, lower wall, jackscrew, suspending weight terminal. Characterized by: prevent a mao pigtail back twist polished rod eye is cuboid hanging wall and cuboid lower wall laminated structure, is equipped with the centre bore, and both ends are equipped with semicircular opening, and the opening installs the pubescence pigtail inside, and outside the hair pigtail, the both ends of hanging wall respectively are equipped with a pin, and the both ends lower part of lower wall is equipped with the semicircle blind hole, and just the position facing to the semicircle blind hole respectively is equipped with a screw through -hole, screw through -hole jackscrew, and the jackscrew is tight with the suspending weight terminal top of hair pigtail lower extreme. The utility model is suitable for a beam -pumping unit horse head is connected with the polished rod, prevents that mao pigtail from beating to turn round, effectively prevents the sucker rod well of lying of threading off, an extension hair pigtail life, and rate when improving the pumpingh well and recovering the oil has lightened post workman's intensity of labour, and guarantee oil pumping motor -pumped well is normally produced.
Description
Technical field
This utility model relates to beam-pumping unit caput Equi Asini and prevents mao plait from returning with light rod connecting device, specifically one
Turn round polished rod eye.
Background technology
The rod-pumped well in oil field is due to the too fast or oily reason such as thick of jig frequency, and it is the most serious that hair plait beats torsion phenomenon.Hair plait
Play torsion to not only result in pumping rod disengaging and lie well, be also easy to cause polished rod break to fall, thus blowout contamination accident occurs.Use routine
After method rectification, owing to when oil pumper is descending, load reduces and the effect of anti-twisted power, hair plait recovers again to beat torsion state, the most whole
Change rate when well not only affects oil recovery of stopping, and the service life of serious curtailment hair plait.
Summary of the invention
The purpose of this utility model is aiming at the drawbacks described above that prior art exists, and design one prevents a mao plait back twist
Polished rod eye.
This utility model is realized by following technical proposals:
Prevent a mao plait back twist polished rod eye, including: hair plait, upper dish, lower wall, jackscrew, suspending weight terminal.Described prevent a mao pigtail
Sub-back twist polished rod eye is upper dish and lower wall overlaying structure, is provided with centre bore, and two ends are provided with semicircle opening, opening built-in hairiness pigtail
Son, outside hair plait, upper dish be respectively arranged at the two ends with a pin, the bottom, two ends of lower wall is provided with semicircle blind hole, just facing to half
The position of circle blind hole is respectively provided with a tapped through hole, and tapped through hole is built with jackscrew, and jackscrew is by the suspending weight terminal of hair plait lower end
Hold out against.
The above-mentioned upper dish prevented in mao plait back twist polished rod eye is cuboid, and two ends are arc surface.
The above-mentioned lower wall prevented in mao plait back twist polished rod eye is cuboid.
The above-mentioned suspending weight terminal prevented in mao plait back twist polished rod eye is provided around annular knurl.
The beneficial effects of the utility model are: be applicable to beam-pumping unit caput Equi Asini and be connected with polished rod, prevent mao plait from playing torsion,
Effectively prevent pumping rod disengaging from lying well, extend hair plait service life.Improve rate when pumpingh well recovers the oil, alleviate post workman's
Labor intensity, ensures that rod-pumped well normally produces.
