Abstract
The utility model discloses a supporting plate for a pumping unit horsehead beam hanger. The supporting plate for the pumping unit horsehead beam hanger is designed for solving the problem that the existing supporting plate of the horsehead beam hanger is difficult to disassemble. Two opposite sides of the end face of the supporting plate are straights, the other two opposite sides of the end face of the supporting plate are inferior arcs, and the supporting plate is provided with a trapezoidal center hole. The supporting plate is arranged on a fixed rod of a wheel disc in a cut-joint mode, an annular gap is formed between the center hole of the supporting plate and the fixed rod, and the supporting plate can rotate around the fixed rod. The annular gap formed between the center hole of the supporting plate and the fixed rod can prevent the adhesion of the center hole of the supporting plate and the fixed rod caused by corrosion, and disassembly is facilitated. When the straight opposite sides of the supporting plate are parallel to a steel wire, the bottom surface of the supporting plate does not contact with the steel wire, and the assembly and disassembly of the supporting plate are facilitated. When the supporting plate rotates to the state that the straight opposite sides of the supporting plate are perpendicular to the steel wire, the bottom surfaces of the inferior-arc shaped opposite sides of the supporting plate press the steel wire to prevent the supporting plate from dropping out. The supporting plate for the pumping unit horsehead beam hanger is safe and reliable, low in manufacture cost, and capable of remarkably reducing labor intensity of workers, saving operation time, avoiding unsafe factors and ensuring regular production of oil wells.
Description
Technical field
The utility model relates to a kind of pumping unit horsehead polished rod eye supporting disk, belongs to oil recovery production gas technology field.
Background technology
The pumping unit horsehead polished rod eye is the flexible connecting member that connects polished rod and horse head, the stress alternation of bearing pumpingh well.In using at the scene, the polished rod eye supporting disk does not have outer protection, and long-term wind-engaging, sand and rain erosion produce corrosion and adhesion.The artificial unloading needs work high above the ground, stressed difficulty, and operation is wasted time and energy, rate when influencing the production of pumpingh well.
Summary of the invention
The purpose of this utility model is to provide a kind of pumping unit horsehead polished rod eye supporting disk, and it can solve the dismounting difficult problem of existing mule-head hanger supporting disk, guarantees the ordinary production of oil well.
Concrete technical scheme of the present utility model is as follows:
Two opposite side of the utility model supporting disk end face are straight shape, and two opposite side are minor arc shape in addition, and supporting disk is provided with trapezoidal centre bore.Supporting disk is sleeved on the fixed bar on the wheel disc, is provided with the annular gap between supporting disk centre bore and the fixed bar, and supporting disk can rotate around fixed bar.
Annular gap between the utility model supporting disk centre bore and fixed bar can prevent both because of the corrosion adhesion, is convenient to dismounting.When the linear opposite side of supporting disk was parallel to wire rope, the supporting disk bottom surface did not contact wire rope, can make things convenient for its loading and unloading.When supporting disk rotation to its linear opposite side during perpendicular to wire rope, the bottom surface of supporting disk minor arc shape opposite side then compresses wire rope, prevents that it from deviating from.The utility model is safe and reliable, and the processing and fabricating cost is low, can obviously reduce personnel labor, the save operation time, avoid producing unsafe factor, and guarantee the oil well ordinary production.

The specific embodiment
Further specify referring to figs. 1 through 4 couples of embodiment of the present utility model:
Embodiment:
Two opposite side of this supporting disk 2 end faces are linear, and two opposite side are minor arc shape in addition, and supporting disk 2 is provided with trapezoidal centre bore.Supporting disk 2 is sleeved on the fixed bar 1 on the wheel disc 3, is provided with the annular gap between supporting disk 2 centre bores and the fixed bar 1, and supporting disk 2 can rotate around fixed bar 1.
During practical operation, rotation supporting disk 2 to its linear opposite side is parallel to the direction of wire rope 4, and at this moment, the bottom surface of supporting disk 2 does not contact wire rope 4, can make things convenient for its loading and unloading.If to the direction of its linear opposite side perpendicular to wire rope 4, at this moment, the minor arc shape opposite side bottom surface of supporting disk 2 then compresses wire rope 4 with supporting disk 2 half-twists, prevent that it from deviating from.
