Description
Technical field
The utility model is related to a kind of oil pipe protective equipment, and in particular to a kind of unidirectional rotating disk of oil pipe anti-eccentric wearing.
Background technology
Structure of oil well can be divided into straight well, horizontal well and inclined shaft, and wherein inclined shaft is forniciform, and straight well and horizontal well are perpendicular
It is straight downward, but because crustal stress changes or cemented the well the factor such as loosely, cause straight well not straight, sleeve pipe bending, internal oil pipe
It can bend, beam hanger moves up and down in oil pipe, direction is integrally fixed at oil pipe friction, long-term friction makes oil pipe and oil
The rubbing surface of bar is badly damaged, and causes pipeline rupture to cause leakage, also results in higher maintenance cost and material replacement cost.
The content of the invention
For defect present in above-mentioned technology, the purpose of this utility model is to provide a kind of in guarantee equipment normal work
Under the premise of, bar, pipe can be made in different directions eccentric wear manually by tubing string rotation direction, uniform state is reached, extend maintenance cycle.
To achieve the above object, the technical scheme that the utility model is taken is：
A kind of unidirectional rotating disk of oil pipe anti-eccentric wearing, including ring flange, wellhead receptacle, upper support body, rolling element, the guarantor of fixed rolling element
Frame, and lower support body are held, and upper support body outer is extended downward at lower support body, and sand and dust entrance is reduced to wrap up rolling element；Institute
It is provided with the outside of the upper support body stated on the inside of crowbar hole, lower support body and is provided with centralizer body, centralizer body external diameter is slightly less than casing inner diameter, helped
Roman internal diameter is slightly larger than oil pipe external diameter, oil pipe is maintained at the center of sleeve pipe.Centralizer body upper end is provided with
Fixed tooth row, upper support body lower end is provided with spring and teeth, and tooth row and teeth cooperate and bearing is rotated clockwise, and
It can not rotate counterclockwise.
Principle of the present utility model is to allow tens of tons of tubing string in ring flange and well head using the bearing effect of rotating disk
Occurs rolling friction between seat, without large-scale workover rig, manpower is just rotatable, and there are spring teeth to fix, and makes it can only
Rotate clockwise, it is ensured that tubing string will not thread off and cause the accident.Rotating tubing string makes oil pipe be worn and torn from different directions with beam hanger, reaches
Even wearing, extends oil pipe service life, extends maintenance cycle.
The utility model is arranged under wellhead flange disk, on wellhead receptacle, can effectively be prevented oil pipe eccentric wear, be made oil pipe
Inwall weares and teares from different directions, reaches even wearing, increases the service life；And rotating disk rotates flexible, a people just can be with complete
Into rotation work, because there is spring teeth to block tooth row, rotating disk will not rebound, and will not also rotate counterclockwise, and can be one by the several months
Cycle, 45 degree of timing rotation can extend maintenance cycle octuple in theory.The utility model is simple to operate, without well maintenance vehicle, one
Workman can complete rotation work, and with low cost, effect is obvious.

Embodiment
Embodiment of the present utility model is specifically described below in conjunction with the accompanying drawings.
Fig. 1 is the unidirectional turntable structure schematic diagram of oil pipe anti-eccentric wearing, including ring flange 1, wellhead receptacle 2, upper support body 3, rolling element
4th, retainer 5, lower support body 6, the upper outer of support body 3 are extended downward at lower support body 6, and the retainer 5 fixes rolling element 4.
The outside of upper support body 3 is provided with crowbar hole 7, and the lower inner side of support body 6 is provided with centralizer body 8.The upper end of centralizer body 8 is set
There is fixed tooth row 9, the upper support body lower end is provided with teeth 10 and spring 11.
It is concrete operation step of the present utility model below：
The first step, closes down oil pumper, holds brake, the unidirectional rotating disk of beam hanger eccentric abrasion prevention is rotated clockwise into 45 degree (to prevent
Beam hanger screw thread is fallen out when turning oil pipe).
Second step, upper liquid pipeline valve is closed, and then unscrews the upper and lower nut of Universal T-joint with pipe wrench.
3rd step, one meter of long crowbar is penetrated the crowbar hole of oil pipe rotating disk, rotates clockwise 45 degree, tighten Universal T-joint
Upper and lower nut.
4th step, opens upper liquid pipeline valve, start production.
Content of the present utility model is not only limited to cited by embodiment, and those of ordinary skill in the art are by reading this reality
Any equivalent transformation taken with new specification technical solutions of the utility model, is claim of the present utility model
Covered.
