Abstract
The utility model relates to a positioning anti-eccentric wear device. An upper sucker rod coupling, a righting rod, and a lower sucker-rod coupling are sequentially connected; a lower fixed sleeve is connected with the upper part of male threads at the lower part of the righting rod; an upper movable sleeve, a centering sleeve, and a lower movable sleeve are sleeved on the righting rod; rail teeth at the lower end of an upper fixed sleeve are meshed with rail teeth at the upper end of the upper movable sleeve; rail teeth at the lower end of the lower movable sleeve are meshed with rail teeth at the upper end of the lower fixed sleeve; the rail teeth at the lower end of the upper fixed sleeve and the rail teeth at the upper end of the lower fixed sleeve are installed in a staggered way; the upper movable sleeve is positioned at the upper part of the centering sleeve; the lower movable sleeve is positioned at the lower part of the centering sleeve; and the upper movable sleeve and the lower movable sleeve are made of metal material, therefore, two sets of rotating mechanisms, which include rail teeth at the lower end of the upper fixed sleeve, at the upper end of the upper movable sleeve, at the lower end of the lower movable sleeve and at the upper end of the low fixed sleeve, can operate normally for a long time, and the centering sleeve can rotate to a certain angle when moves up and down each time, so that a wear part of the centering sleeve is increased, eccentric wear can be prevented, and obvious economic benefit can be achieved.
Description
Technical field
The utility model is the device of using in the oil field pumping well, is the anti-eccentric wear device in a kind of location.
Background technology
In the oil pumping system of oil field, R a T has relative contact movement, certainly existing between sucker rod and the oil pipe and rubbing, and the wearing and tearing of sucker rod, oil pipe also just inevitably occurred.Particularly deep-well and inclined shaft, sucker rod is easy to bending in oil pipe, the problem that serious sucker rod partial wear oil pipe occurs, after producing eccentric wear oil pipe and sucker rod can not be used, cause the oil well operation, oil well repair free period is short, increase operating cost, increase rod tube consumption, the oil well off-time is many, reduces crude output.The normal problem that adopts oil pumping rod centering device to solve oil pipe and sucker rod partial wear on the oil recovery technique.But make the mechanism of supporting positive cover rotation not wear-resistant on the existing oil pumping rod centering device, frictional resistance is big, the rotation difficulty, make supporting positive cover have only a position to be worn, cause oil pumping rod centering device short application life, the frequent problem of workover rig service to oil well is not resolved, and the pumpingh well economic benefit is low.
Summary of the invention
The purpose of this utility model is the anti-eccentric wear device in a kind of location of design, and its supporting positive cover can effectively be rotated, and increases the wear-resisting position of supporting positive cover, prolongs the application life of supporting positive cover.
The purpose of this utility model is achieved in that by last rod collar, last fixed cover, go up moving cover, supporting positive cover, moving down cover, righting rod, following fixed cover, the lower sucker rod box cupling is formed, last rod collar is connected with righting rod top, the righting rod bottom is connected with the lower sucker rod box cupling, last fixed cover is connected with the bottom of righting rod top male thread, last fixed cover is under the rod collar, following fixed cover is connected with the top of righting rod bottom male thread, following fixed cover is on the lower sucker rod box cupling, go up moving cover, supporting positive cover, moving down being sleeved on the righting rod, there is the track tooth last fixed cover lower end, go up moving set upper side the track tooth is arranged, the track tooth of last fixed cover lower end is meshed with the track tooth of last moving set upper side, there is the track tooth moving down cover lower end, there is the track tooth following fixed cover upper end, the track tooth of moving down cover lower end is meshed with the track tooth of following fixed cover upper end, the track tooth of last fixed cover lower end, go up the track tooth of moving set upper side, the track tooth of moving down cover lower end, the track odontoid of fixed cover upper end and measure-alike, the track tooth arranged in dislocation of the track tooth of last fixed cover lower end and fixed cover upper end, go up the moving top that is fixed on supporting positive cover of overlapping, moving down cover is fixed on the bottom of supporting positive cover, goes up moving cover, moving down cover is metal material.
The beneficial effects of the utility model are: go up the top that moving cover is positioned at supporting positive cover, moving down cover is positioned at the bottom of supporting positive cover, go up moving cover, moving down cover is metal material, therefore, the track tooth of last fixed cover lower end, go up the track tooth of moving set upper side and the track tooth of down moving cover lower end, the two cover rotating mechanisms that the track tooth of fixed cover upper end is formed are operate as normal for a long time, the each up-downgoing of supporting positive cover can both rotate to an angle, increased supporting positive cover the abrading section, can prevent eccentric wear, can prolong the application life of supporting positive cover, thereby prolong the application life of oil pumping system, have remarkable economic efficiency.
