Abstract
A polished rod eye slightly-adjusting device comprises a polished rod eye body. A polished rod of a sucker rod is fixed on the polished rod eye body. The polished rod eye body parts located on the two sides of the polished rod are provided with symmetric adjusting pull bars. The adjusting pulling bars are in threaded connection with the polished rod eye body. The adjusting pull bars on the lower parts of the polished rod eye are provided with nuts. Belts are fixed on the upper parts of the adjusting pull bars. The pull bars on the two sides of the polished rod are parallel to each other. The polished rod is parallel to the pull bars. The device is applied for adjusting the lengths of the belts on the two sides and reducing the length difference between the left belt and the right belt. In case the belts are different in length, the horizontal degree of the polished rod eye can be simply and conveniently adjusted by adjusting the connecting nuts on the lower parts of the adjusting pull bars. Then the verticality for the polished rod of the sucker rod to move vertically is improved. The wear extent of the polished rod and the sucker rod can be alleviated. The service lifetime of an oil well pump can be prolonged.
Description
Technical field
The utility model relates to polished rod eye, relates to a kind of micromatic setting that is applied in the polished rod eye on the oil pumper specifically.
Background technology
At present; Link together through polished rod eye and belt at the oil pumping machine oil pumping bar; The polished rod of sucker rod is fixed on the polished rod eye in the middle of two belts, owing to be to be fixedly connected between belt and polished rod eye and polished rod eye and the polished rod, two variant verticality that will have influence on the polished rod on the polished rod eye of Belt Length size; Thereby increase the wearing and tearing of polished rod and sucker rod, shorten the application life of oil well pump.
Summary of the invention
The purpose of the utility model just is to overcome above-mentioned deficiency a kind of polished rod eye micromatic setting is provided.
The purpose of the utility model can realize through following measure:
A kind of polished rod eye micromatic setting; Comprise the polished rod eye body; The polished rod of sucker rod is packed on the polished rod eye body, on the polished rod eye body of polished rod both sides, is symmetrically arranged with the adjustment pull bar, and the adjustment pull bar is to be threaded with the polished rod eye body; On the adjustment pull bar of polished rod eye body bottom, nut is set, belt is fixed on adjustment pull bar top.
Above-mentioned polished rod eye micromatic setting, the pull bar of said polished rod both sides is parallel to each other, and polished rod and pull bar are parallel to each other.
Adopt technique scheme, the utility model has following advantage: this device is used to adjust the length of bilateral belt, reduces the difference of two Belt Length sizes.Under the situation that left side belt and right side Belt Length differ, the attaching nut through adjustment pull bar lower end can adjust the levelness of polished rod eye body simply, easily, thereby improves the verticality that the polished rod of sucker rod moves up and down.Reduce the wear extent of polished rod, sucker rod, improved application life of oil well pump.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
A kind of polished rod eye micromatic setting as shown in Figure 1 comprises polished rod eye body 4, and the polished rod 6 of sucker rod is packed on the polished rod eye body 4; On the polished rod eye body 4 of polished rod 6 both sides, be symmetrically arranged with adjustment pull bar 3; Adjustment pull bar 3 is to be threaded with the polished rod eye body, on the adjustment pull bar 3 of polished rod eye body bottom, nut 5 is set, and belt is fixed on adjustment pull bar 3 tops; The pull bar 3 of said polished rod 6 both sides is parallel to each other, and polished rod 6 is parallel to each other with pull bar.
This device is used to adjust the length of bilateral belt, reduces the difference of two Belt Length sizes.Under the situation that left side belt 1 and right side belt 2 length differ, the attaching nut 5 through adjustment pull bar 3 lower ends can adjust the levelness of polished rod eye body 4 simply, easily, thereby improves the verticality that the polished rod 6 of sucker rod moves up and down.Reduce the wear extent of polished rod, sucker rod, improved application life of oil well pump.
