Description
Technical field
The utility model relates to a kind of centralizer, is specifically related to a kind of well head pipe fitting Bidirectional stabilizing device.
Background technology
In China oil production process, oil well polished rod eccentric wear phenomenon is more serious, and the pipe fitting eccentric wears such as polished rod can cause crude oil leakage to cause pollution in wide area, therefore people are normal adopts various improved borehole centralizers to carry out righting to oil well pipe fitting, prevents the generation of the problems referred to above.And various improved borehole centralizer majorities are got used to from consider pipe fitting righting problem perpendicular to well head horizontal direction, the righting that well head pipe fitting is considered is in the horizontal direction less, and righting often can not get a desired effect fast, and makes righting inefficiency, waste time and energy, cause work fatigue.
Utility model content
The utility model is exactly for the problems referred to above, and a kind of centralizer that can carry out to well head pipe fitting vertical and horizontal bidirectional righting is provided, and promotes the righting effect of well head pipe fitting.
The technical scheme that the utility model adopted is for achieving the above object:
A kind of well head pipe fitting Bidirectional stabilizing device comprises that main installing plate, secondary installing plate, motor, power are flexible, righting arm, centering ring and dovetail slide, described main installing plate, motor are vertically fixed on secondary installing plate, motor is connected with main installing plate, the middle part of main installing plate connects one end of righting arm, the other end of righting arm is connected with centering ring, and secondary installing plate is connected with power is flexible.
It is parallel with motor that described main installing plate is fixedly mounted on the left side of motor.
On described main installing plate, be horizontally disposed with rotating shaft, one end of righting arm is fixed in rotating shaft.
Described motor is connected with rotating shaft, drives righting arm rotation, in the direction perpendicular to paper by pipe fitting righting.
The inside, right side of described secondary installing plate is provided with slide plate, and described slide plate can be dovetail slide or cross sliding board.
Described slide plate slides is arranged in the chute of fixed head, chute closed at both ends.
The telescopic end of described power stretching device is connected with slide plate through the blind end of chute.
One gearbox also can be set between described main installing plate and motor, and gearbox is vertically fixed on secondary installing plate, the rotating speed of the controlled rotating shaft of this gearbox, regulates the righting speed in vertical paper direction, makes righting adjustment process more careful.
When power stretching device promotes secondary installing plate and moves horizontally, pipe fitting is in the horizontal direction by righting, the rotation of driven by motor righting arm, pipe fitting in the direction perpendicular to paper by righting, thereby make pipe fitting Bidirectional stabilizing.
The utlity model has following advantage and beneficial effect:
The dovetail slide of secondary installing plate rear side is connected with the telescopic end of power stretching device, power stretching device promotes secondary install bin righting pipe fitting horizontal direction, driven by motor righting arm is righting pipe fitting vertical paper direction, make pipe fitting aim at well head from horizontal and vertical direction, than existing unidirectional righting more comprehensively, fast, operating efficiency is high in righting.
