Abstract

The utility model provides a beam -pumping unit school mechanic's utensil, includes: floor (0), cross arm (1), jack (2), title (3), gyro wheel (4), bearing (5), axle (6), characterized by: beam -pumping unit school mechanic's utensil's the upper portion of jack (2) be equipped with a title (3), the upper portion symmetry of a title (3) is equipped with bearing (5), axle (6) is fixed gyro wheel (4) in a centre of calling (3) through bearing (5), the upper portion of gyro wheel (4) is equipped with cross arm (1). The utility model is suitable for an oil field beam -pumping unit school machine only needs the operation of two people to accomplish, has reduced post workman's intensity of labour, shortens between the machine -hour of school, avoids because of stopping the chronic oil well well of lying that causes of well, and operation safety makes the polished rod placed in the middle, reduces the wearing and tearing of packing and the inclined to one side mill of pipe pole, reduces reactive loss, improvement pumpingh well system efficiency.

Description

Beam pumping unit school machine instrument
Technical field
The utility model relates to beam pumping unit well servicing school, oil field machine special tool, specifically a kind of beam pumping unit school machine instrument.
Background technology
At present, the running of oil extractor in oil field time is general longer, and sink and oil pumper can be caused to offset in basis, the skew of oil pumper can cause well head to offset, the eccentric wear of the polished rod brought thus and the wearing and tearing of packing and pipe bar both increases reactive loss, reduces system effectiveness; The simultaneously friction of horse head edge and hair plait, causes that mao plait is disconnected, light rod-broken, adds operation cost, cost of materials.General rod-pumped well 1-2 needs school machine once, complicated operation, and school machine generally divides two kinds of modes: one is, report oil pumper fitting-up gang, reports one, 25 tons of cranes, teams and groups about 7 people, first pluck pumping unit load in operating process, carry out integral hoisting oil pumper, correct to correct position, two are, note adopts school machine voluntarily of standing, need electrogas welding a set of, personnel four people coordinates and can complete, first pumping unit load is plucked in operating process, according to school machine needs, oil pumper base is slotted or places jack at pressure thick stick place, jack-up oil pumper both sides manually prize oil pumper with crowbar, fluting like this easily destroys oil pumping support stress structure, and meeting bending i iron or pressure thick stick channel-section steel, labour intensity is large simultaneously, length consuming time, oil well is caused to stop well overlong time, thus oil well sand card may be caused, easily skid when operating jack simultaneously, there is larger potential safety hazard.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of beam pumping unit school machine instrument.
Technical solutions of the utility model comprise:
Beam pumping unit school machine instrument, comprising: floor, cross-arm, jack, title, roller, bearing, axle.The top of the jack of described beam pumping unit school machine instrument is provided with a title, and a portion of being much of is arranged with bearing, and roller is fixed on a centre claimed by bearing by axle, and the top of roller is provided with cross-arm.
In the machine instrument of above-mentioned beam pumping unit school, the cross section of cross-arm is rectangular bow-shaped structural, and two ends are provided with triangle floor.
Propping up in the machine instrument of above-mentioned beam pumping unit school is called " U " type structure, and both sides, top are arranged with stairstepping through hole.
Roller cylindrical in the machine instrument of above-mentioned beam pumping unit school is provided with decorative pattern.
The front end of above-mentioned beam pumping unit school machine instrument axis is provided with square toes.
Operating principle: beam pumping unit school machine instrument make use of the principle of balancing beam; cross-arm is stuck in the inner side of the i iron of oil pumping unit base; roller above jack is placed in the middle of bottom cross-arm; after oil pumper jack-up; utilize ratchet spanner shifting roller; thus drive oil pumper to move, reach the object of school machine.
The beneficial effects of the utility model are: be applicable to beam pumping unit school, oil field machine; two people's operations are only needed to complete; reduce the labour intensity of post workman; shortening the school machine time, avoiding because stopping the well time long and cause oil well to lie well, handling safety; make polished rod placed in the middle; reduce the wearing and tearing of packing and the eccentric wear of pipe bar, reduce reactive loss, improve pumpingh well system effectiveness.
Accompanying drawing explanation
Fig. 1-the utility model scene application broken section structural representation.
In figure, 0. floor, 1. cross-arm, 2. jack, 3. a title, 4. roller, 5. bearing, 6. axle, 7. oil pumping unit base, 8. support.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in drawings,
Beam pumping unit school machine instrument is made up of floor 0, cross-arm 1, jack 2, a title 3, roller 4, bearing 5, axle 6.The top of the jack 2 of described beam pumping unit school machine instrument is provided with " U " type and props up title 3; the top of propping up title 3 is arranged with bearing 5; cylindrical establishes dapple roller 4 to be fixed on the centre of a title 3 by bearing 5 by axle 6, and it is rectangular cross-arm 1 that the top of roller 4 is provided with cross section.
Method of operating:
First, shut down and horse head is parked in close to lower dead point position, load removal;
Secondly, loosen oil pumper pressure thick stick bolt, distance reaches 3 ~ 5cm;
3rd, cross-arm 1 is stuck in the inner side of the i iron of oil pumping unit base 8, the roller 4 above jack 2 is placed in the middle of bottom cross-arm 1, if need to carry out adjusting before and after oil pumper, then the direction of roller 4 is identical with oil pumper direction, if adjusted about needing to carry out oil pumper, then the direction of roller 4 is vertical with oil pumper direction, after oil pumper jack-up, ratchet spanner is utilized to block the square toes of axle 6, shifting roller 4, drives oil pumper, reaches the object correcting oil pumper.
