Abstract
The invention discloses a horsehead polished rod eye supporting plate of an oil pumping unit, which is designed for solving the problem of disassembling the conventional horsehead polished rod eye supporting plate. The two opposite edges of the end surface of the supporting disk are linear, the other two opposite edges are minor arcs, and the supporting disk is provided with a trapezoidal central hole. The supporting disk suit is equipped with the annular gap on the dead lever on the rim plate between supporting disk centre bore and the dead lever, and the supporting disk can rotate around the dead lever. The annular gap between the central hole of the support plate and the fixed rod can prevent the support plate and the fixed rod from being adhered due to corrosion, and is convenient to disassemble. When the straight-line-shaped opposite sides of the supporting plate are parallel to the steel wire rope, the bottom surface of the supporting plate is not contacted with the steel wire rope, so that the supporting plate can be conveniently assembled and disassembled. When the support plate rotates to the state that the linear opposite side of the support plate is perpendicular to the steel wire rope, the bottom surface of the inferior arc opposite side of the support plate compresses the steel wire rope to prevent the steel wire rope from falling off. The invention has the advantages of safety, reliability and low processing and manufacturing cost, can obviously reduce the labor intensity of staff, saves the operation time, avoids unsafe factors and ensures the normal production of an oil well.
Description
Technical field
The present invention relates to a kind of pumping unit horsehead polished rod eye and prop up support plate, belong to oil recovery production gas technology
Field.
Background technology
Pumping unit horsehead polished rod eye is to connect polished rod and the flexible connecting member of caput Equi Asini, bears oil pumping
The stress alternation of well.In using at the scene, polished rod eye props up support plate without outer protection, is subject to for a long time
Wind, sand and rain erosion, produce corrosion and adhesion.Artificial unloading needs work high above the ground, stress
Difficulty, operation is wasted time and energy, and affects the production time efficiency of pumpingh well.
Summary of the invention
It is an object of the invention to provide a kind of pumping unit horsehead polished rod eye and prop up support plate, it can solve
Certainly existing mule-head hanger props up a dismounting difficult problem for support plate, it is ensured that the normal production of oil well.
The concrete technical scheme of the present invention is as follows:
It is straight that the present invention props up two opposite side of support plate end face, and another two opposite side are minor arc shape, supports
Dish is provided with trapezoidal centre bore.Prop up on the fixing bar that support plate is sleeved on wheel disc, in a support plate
Being provided with annular gap between central hole and fixing bar, a support plate can rotate around fixing bar.
The present invention supports the annular gap between center hole and fixing bar and both can be prevented because of corrosion
And adhesion, it is simple to dismounting.When the linear opposite side of a support plate is parallel to steel wire rope, support
Face of trying to get to the heart of a matter does not contacts steel wire rope, and it can be facilitated to load and unload.Spiral when support and go to its linear pair
During while be perpendicular to steel wire rope, the bottom surface of a support plate minor arc shape opposite side then compresses steel wire rope, prevents
Its abjection.The present invention is safe and reliable, and processing and fabricating cost is low, can substantially reduce the labor of employee
Fatigue resistance, saves the operating time, it is to avoid produce unsafe factor, it is ensured that oil well normally produces.
Accompanying drawing explanation
Fig. 1,2 prop up schematic diagram when support plate does not contact steel wire rope for pumping unit horsehead polished rod eye.
Fig. 3,4 for pumping unit horsehead polished rod eye prop up support plate compress steel wire rope time schematic diagram.
Detailed description of the invention
Further illustrate referring to figs. 1 through 4 pairs of embodiments of the invention:
Embodiment:
Two opposite side of this support plate 2 end face are linear, and another two opposite side are minor arc shape, support
Dish 2 is provided with trapezoidal centre bore.Prop up support plate 2 to be sleeved on the fixing bar 1 on wheel disc 3,
Propping up and be provided with annular gap between support plate 2 centre bore and fixing bar 1, a support plate 2 can be around fixing
Bar 1 rotates.
During practical operation, rotary support tray 2 is parallel to steel wire rope 4 to its linear opposite side
Direction, now, the bottom surface of a support plate 2 does not contact steel wire rope 4, and it can be facilitated to load and unload.If will
Support plate 2 half-twist is perpendicular to the direction of steel wire rope 4 to its linear opposite side, now,
The minor arc shape opposite side bottom surface propping up support plate 2 then compresses steel wire rope 4, prevents it from deviating from.
