Abstract

The utility model discloses a beam hanger and relates to the technical field of a pumping unit. The beam hanger is characterized by comprising a ball (4) and a beam (5); a center through hole is formed in the beam (5), and the upper end of the center through hole is connected with a ball socket (8); a center through hole is formed in the ball (4); the ball (4) is arranged in the ball socket (8), and the ball (4) and the ball socket (8) form a sphere kinematic pair; and when the ball (4) and the beam (5) are aligned, axis lines of the center through hole of the beam (5) and the center through hole of the ball (4) are coincided. In the operation process, when a polished rod deviates, automatic centering of the polished rod is realized by coadjusting the sphere kinematic pair of the ball and the ball socket of the beam; and an adjustment range of the sphere kinematic pair is large, so that the phenomenon of blind of the ball and the beam cannot appear.

Description

A kind of polished rod eye
Technical field
The utility model relates to the oil pumper technical field, is specifically related to a kind of polished rod eye of oil pumper.
Background technology
In the oil extraction in oil field mechanism, adopted has rod recovering system more.Oil pumper is converted into rotatablely moving of power the rectilinear motion of polished rod, and the flexible piece on oil pumper (as wire rope, belt etc.) will be connected with polished rod by polished rod eye.Due to the error of installing or the error of oil pumper manufacturing process, can cause suspension point and well head to misalign in the installation process of oil pumper; Will make like this lifting rope partially draw polished rod, thereby cause polished rod crooked; The bending of polished rod not only can make the polished rod life-span reduce, also can the eccentric wear well head packing, cause the packing of changing more frequently the wellhead sealing box.
provide following solution about deviation adjusting beam hanger in prior art: be the Chinese patent application of ZL201020293240.2 as the patent No., a kind of deviation adjusting beam hanger of pumping unit is disclosed, polished rod eye is specifically arranged, polished rod, adjustment plate forms, adjustment plate is arranged on polished rod eye, the hemispherical adjustment plate is combined with polished rod eye episphere connected in star, have the advance and retreat groove on adjustment plate, the center of circle that circular hole in polished rod eye is departed from the center of circle of advance and retreat circular arc side, groove end, when adjustment plate is rotated on polished rod eye, driving the advance and retreat groove rotates, realization is in the situation that polished rod is motionless by adjusting adjustment plate, polished rod eye and polished rod are not produced suppress strength, and then the vertical state of maintenance polished rod, prevent that sealer from crossing quick-wearing.But the adjustment plate in hemispherical cross section and polished rod eye adjusting range are limited, even can cause adjustment plate and polished rod eye stuck under extremity, thereby can not well play the effect of adjusting polished rod.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention technical problem to be solved is to provide a kind of polished rod eye of adjusting on a large scale flexibly the polished rod state.
The invention is that the technical scheme that its technical problem of solution adopts is:
A kind of polished rod eye comprises bulb, crossbeam, and described crossbeam is provided with central through hole, and central through hole upper end connection ball-and-socket; Described bulb is provided with central through hole, and bulb is arranged in ball-and-socket, and both form the spheric motion pair; Bulb and crossbeam be to timing, crossbeam central through hole and the dead in line of bulb central through hole.
Further, described ball-and-socket spherical diameter is greater than the bulb spherical diameter.
Further, described crossbeam two ends are provided with the prong of being convenient to the lifting rope turnover, and the prong bottom is provided with for the circular trough of placing the lifting rope fag end.
Further, also comprise block, described block is fixed by screws in the prong place, is used for stopping that the lifting rope that is in place withdraws from.
Further, described crossbeam upper length direction two ends are provided with stepped recesses.
In operation process, when polished rod departed from, the mutual adjusting of the spheric motion pair by bulb and crossbeam ball-and-socket realized the automatic centering of polished rod; And the adjusting range of spheric motion pair is large, the stuck phenomenon of bulb and crossbeam can not occur.
Description of drawings
Accompanying drawing described herein is used to provide the further understanding to the invention, consists of the application's a part.Illustrative examples and explanation thereof are used for explaining the invention, do not consist of the improper restriction to the invention.Give in accompanying drawing:
Fig. 1 is the schematic diagram that nest ball formula polished rod eye uses state;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the structural representation of nest ball formula polished rod eye crossbeam;
Fig. 4 is the upward view of Fig. 3;
Fig. 5 is the top view of Fig. 3;
The specific embodiment
Below with reference to the drawings and specific embodiments, further illustrate the invention.
In conjunction with Fig. 1, Fig. 2, the polished rod eye of the present embodiment comprises bulb 4, crossbeam 5, and bulb 4, crossbeam 5 are equipped with central through hole, and crossbeam 5 central through hole upper end connection ball-and-sockets 8; Bulb 4 is arranged in ball-and-socket 8, and both form the spheric motion pair; Ball-and-socket 8 spherical diameters are greater than bulb 4 spherical diameters.5 pairs of timings of bulb 4 and crossbeam, crossbeam 5 central through holes and bulb 4 central through hole deads in line.
In conjunction with Fig. 3-Fig. 5, crossbeam 5 upper length direction two ends are provided with stepped recesses 11; Crossbeam 5 two ends are provided with the prong 9 of being convenient to lifting rope 1 turnover, and the prong bottom is provided with for the circular trough 10 of placing lifting rope 1 fag end.
During application, polished rod 2 passes from crossbeam and bulb centre bore, and optical-rod clamp 3 tightly blocks polished rod, and lifting rope 1 is positioned at prong 9 places by screw 7 and block 6, is used for stopping that the lifting rope that is in place withdraws from; Optical-rod clamp 3 is due to down-hole load effect, drops on bulb 4 upper ends.The mutual adjusting of the spheric motion pair by bulb and crossbeam ball-and-socket realizes the automatic centering of polished rod.
