Abstract
The utility model discloses a kind of unidirectional rotating disk of beam hanger eccentric abrasion prevention, including horsehead rope, polished rod eye, polished rod, Fang Ka, upper support body, rolling element, lower support body.The horsehead rope lower end is provided with polished rod eye, is provided with support body between the polished rod eye and Fang Ka, is rolling element below the upper support body, arranges lower support body below the rolling element, and the polished rod is through in the middle part of polished rod eye, CUSTOM HOUSE HOTEL；Be provided with crowbar hole on the outside of the upper support body, between several rolling elements by retainer fix between distance, be provided with fixing tooth row on the inside of the lower support body, with upper support body on the inside of spring, teeth coordinate, be provided with spring in the teeth.The utility model is made simply, with low cost, can effectively prevent beam hanger eccentric wear.
Description
Technical field
The utility model is related to a kind of beam hanger protective equipment, and in particular to a kind of unidirectional rotating disk of beam hanger eccentric abrasion prevention.
Background technology
Oil well can be divided into straight well, horizontal well and inclined shaft from structure, and wherein inclined shaft is bending, and straight well and horizontal well are
Straight down, but as crustal stress changes or the well cementation factor such as loosely, sleeve pipe is caused to sink bending, straight well and horizontal well also become
Straight, sleeve pipe bends, and internal oil pipe can also bend, and beam hanger is moved up and down in oil pipe for a long time, is frictionally secured with oil pipe
In a direction, because being connected by box cupling between beam hanger, and beam hanger box cupling external diameter is more than beam hanger external diameter, so typically beam hanger connects
Hoop is first frayed, and long-term friction can make the rubbing surface of beam hanger box cupling be badly damaged, cause screw thread worn out occur disconnected de-, maintenance cost and
Nearly ten thousand yuan of fee of material.
Content of the invention
For defect present in above-mentioned technology, the purpose of this utility model is to provide one kind to ensure equipment normal work
On 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 week
Phase.
Prior art is solved the problems, such as, the technical scheme that takes is：A kind of unidirectional rotating disk of beam hanger eccentric abrasion prevention, including donkey
String for binding a plait, polished rod eye, polished rod, Fang Ka, upper support body, rolling element, lower support body.The horsehead rope lower end is provided with polished rod eye, described outstanding
Support body is provided between rope device and Fang Ka, is rolling element below the upper support body, lower support body, institute are set below the rolling element
Polished rod is stated through polished rod eye, side card middle part；Crowbar hole is provided with the outside of the upper support body, by keeping between several rolling elements
Frame fix between distance, be provided with fixing tooth row on the inside of the lower support body, with upper support body on the inside of spring, teeth coordinate, described
Spring is provided with teeth.
Operating principle of the present utility model is：First oil pumper is closed down, brake is held, then crowbar is penetrated driving hole,
Support body is rotated clockwise, upper support body drive side card, square cassette tape move polished rod and rotate, can be that cycle timing turns by a few days or several months
Dynamic, make the rubbing surface between OIH bar and oil pipe reach uniform state, effectively prevent all the time wear and tear one and, the silk for causing
Button is worn out to cause disconnected taking off.
The beneficial effects of the utility model are：Beam hanger eccentric wear can be effectively prevented, so that beam hanger surface is worn and torn from different directions,
Even wearing is reached, increases service life, extend maintenance cycle, and rotating disk flexibility is very good, a people can just complete
Rotation work, because there is spring teeth to block tooth row, rotating disk will not rebound, and will not also rotate counterclockwise, regularly to beam hanger up time
Pin is rotated, and is also prevented from beam hanger and is threaded off.The utility model is simple to operate, with low cost, and effect is obvious.

Specific embodiment
Fig. 1 is overall structure diagram of the present utility model, including horsehead rope 1, polished rod eye 2, polished rod 3, side's card 4, upper support
Body 6, rolling element 7, lower support body 9.1 lower end of the horsehead rope is provided with polished rod eye 2, is provided between the polished rod eye 2 and Fang Ka 4
Upper support body 6,6 lower section of the upper support body is rolling element 7, and 7 lower section of the rolling element arranges lower support body 9, and the polished rod 3 passes through outstanding
Rope device 2,4 middle part of side's card；It is characterized in that the outside of the upper support body 6 is provided with crowbar hole 13, by protecting between several rolling elements 7
Distance between the fixation of frame 8 is held, 9 inner side of the lower support body is provided with fixing tooth row 10, the spring 12, teeth with 6 inner side of upper support body
11 coordinate, and are provided with spring 12 in the teeth 11.
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 that technical solutions of the utility model is taken with new specification, is claim of the present utility model
Covered.
