Abstract

A connecting disc is formed by connecting a left disc and a right disc, inner rings of the left disc and the right disc are connected with a contact plate through springs, and the contact plate is provided with an anti-skid pad; the surfaces of the left disc and the right disc are symmetrically provided with sliding chutes; the left disc and the right disc are connected through bolts; the left and right discs of the connecting disc penetrate through the sliding groove through bolts to be connected with a well mouth or a pipe orifice, the size of the inner diameter of the connecting disc is adjusted through the formation of the sliding groove according to the size of the oil rod until the contact plate is attached to the surface of the oil rod, the positions of the left and right discs are fixed through the bolts, the size is fixed, and the oil rod is always pushed towards the center under the action of a spring in the pumping of the oil rod, so that the position of the oil rod is adjusted; the utility model can effectively center the oil rod, is suitable for centering the oil rods with different pipe orifices, can adjust the inner diameter size, does not deviate the oil rod and prolongs the service life of the polish rod.

Description

Centering adjusting disc for oil rod

Technical Field

The utility model belongs to the technical field of crude oil exploitation, and particularly relates to a centering adjusting disc for an oil rod.

Background

When the cement foundation is installed to the pumping unit, the foundation is tamped and is handled nonstandard, and the rainwater invasion easily causes the foundation to sink in production, and the pumping unit installation is just, and eccentric wear phenomenon is serious, and the beam-rod and seal box friction deformation, well head sealing device are promptly: the sealing ring is easy to wear, so that the sealing performance is poor, the oil leakage at the wellhead is caused, the environment is polluted, and the resources are wasted. And the sealing ring, the sealing box and the first oil rod are required to be frequently replaced, so that the oil extraction cost is increased. The oil engine mounting base is not standard, so that the phenomena of foundation sinking, improper oil pumping machine and eccentric wear of an oil rod are easily caused; the installation design of a well head is unreasonable, the oil rod centering regulator is not provided, the eccentric wear of the oil rod is serious, the oil rod and the sealing box are easy to wear, the service life is naturally shortened, and the oil extraction production cost is high for a long time; the oil extraction worker has high labor intensity, the oil rod is eccentric-worn, the sealing ring is easy to wear and has poor sealing performance, the oil rod needs to be frequently replaced, the workload is large, the labor intensity is high, and therefore, the design defects of the wellhead device of the oil pumping machine can be seen, the oil rod is eccentric-worn due to the oil rod-free centering device, the oil production cost is high, the sealing performance is poor, the oil leakage of the wellhead is caused, the environment is polluted, and resources are wasted. The sealing washer is frequently changed to the oil production worker, and work load is big, and intensity of labour is high, relies on manual the going on during the change, and unsettled operation potential safety hazard is many.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model aims to provide a centering adjusting disc for an oil rod, so that the adjusting oil rod and a wellhead are in a central position, and the adjusting oil rod and the wellhead are in a central position; the up-and-down reciprocating motion of the horse head is always in the same line with the well mouth, so that the pipe column does not return, runs stably and can be applied to different pipe orifices. The ideal effect is achieved, and the service life of the polish rod is prolonged; energy conservation and consumption reduction.

In order to overcome the defects of the prior art, the utility model adopts the technical scheme that:

the utility model provides a pole adjusting plate placed in middle, includes the connection pad, its characterized in that, and the connection pad is connected by left side dish, right side dish and is constituteed, and left side dish, right side dish inner circle pass through spring coupling contact plate, are equipped with the slipmat on the contact plate.

The surfaces of the left disc and the right disc are symmetrically provided with sliding chutes.

The left disc and the right disc are connected through bolts.

The utility model has the beneficial effects that:

the utility model can effectively center the oil rod, is suitable for centering the oil rods with different pipe orifices, can adjust the inner diameter size, does not deviate the oil rod and prolongs the service life of the polished rod.

Drawings

FIG. 1 is a schematic structural diagram of the present invention.

Wherein, 1 is a connecting disc; 2 is a left disc; 3 is a right disc; 4 is a spring; 5 is a contact plate; 6 is an anti-skid pad; 7 is a chute; and 8 is a bolt.

Detailed Description

The utility model is further described below with reference to the accompanying drawings.

As shown in figure 1, the centering adjusting plate for the oil rod comprises a connecting plate 1 and is characterized in that the connecting plate 1 is formed by connecting a left plate 2 and a right plate 3, inner rings of the left plate 2 and the right plate 3 are connected with a contact plate 5 through springs 4, and an anti-skid pad 6 is arranged on the contact plate 5.

The surfaces of the left disc 2 and the right disc 3 are symmetrically provided with sliding chutes 7.

The left disc 2 and the right disc 3 are connected through a bolt 8.

The working principle of the utility model is as follows:

the left and right discs of the connecting disc penetrate through the sliding groove through the bolts to be connected with a wellhead or a pipe orifice, the positions of the left disc and the right disc are adjusted through the stroke of the sliding groove according to the size of the oil rod, the purpose of adjusting the inner diameter size of the connecting disc is achieved, the contact plate is attached to the surface of the oil rod until the contact plate is attached to the surface of the oil rod, the positions of the left and right discs are fixed through the bolts, the size is fixed, the oil rod is pushed towards the center all the time under the action of the spring in the pumping of the oil rod, and the position of the oil rod is adjusted.
