Abstract

The utility model relates to a ground balancing device of a pumping unit, which consists of a fixing bolt, a pumping unit crank and a pumping unit balancing block. The pumping unit balancing block is fixed on the output shaft of a pumping unit gearbox by the fixing bolt; the pumping unit balancing block is arranged at the side with the pumping unit crank; the fixing bolt penetrates through a lower hole at the left end of a bracket to fix the bracket on the pumping unit crank; the wheel positioning hook of a sprocket is hanged on the bracket; and the driving wheel of the sprocket is used for hanging the pumping unit balancing block. Because of the force-reducing function of the sprocket, the operating worker can easily pull the sprocket while standing on the ground, so that the pumping unit balancing block can move downwards under the effect of the gravity thereof. Therefore, the utility model can achieve the design purpose, has the advantages of time and labor saving performance, low labor intensity for operating workers, no requirement for high-altitude operation and no danger, can conveniently and rapidly move the pumping unit balancing block to the desired position, and has no influence on the working process. The downtime of the pumping unit is short; the delay time on the production is short; and the economic benefits are high.

Description

Oil pumper ground balancing device

One, technical field

The utility model is that oil-field oil pumper is adjusted equipment, is a kind of oil pumper ground balancing device.

Two, background technology

The balance weight of oil pumper needs often to adjust the position; could satisfy on the oil pumper; balance requirement during down stroke; adjusting balance is exactly the position of adjusting balance weight; the position of adjusting balance weight need move to the balance weight of several tons of weights the another one position; the method of present on-the-spot balancing is; unload loose balance weight fixed screw earlier, prize balance weight with crowbar again, because balance weight has several tons of weights; therefore; prize very slow; effort, owing to be work high above the ground, the operator is dangerous big; cause personal injury easily; the shutdown of pumping machine time is long, delays production, influences oil well output.

Three, summary of the invention

The purpose of this utility model is a kind of oil pumper of design ground balancing device, can easily and efficiently the balance of well pumping unit piece be moved to the position that needs.

The purpose of this utility model is achieved in that by set bolt, oil pumping machine crank, balance of well pumping unit piece to be formed, and set bolt is fixed on the oil pumping unit reduction gearbox output shaft balance of well pumping unit piece, and the balance of well pumping unit piece is installed in the oil pumping machine crank side.Set bolt is through in the support left end bottom hole, and support is fixed on the oil pumping machine crank, and the fixed wheel hook of sprocket wheel is suspended on the support, and the driving wheel of sprocket wheel hangs the balance of well pumping unit piece.

The beneficial effects of the utility model are: because sprocket wheel has laborsaving effect; the operator stands in ground and easily spurs sprocket wheel the balance of well pumping unit piece is moved down under the self gravitation effect, and therefore, the utility model can reach purpose of design; time saving and energy saving; operator's labour intensity is low, and not work high above the ground is safe from danger; can easily and efficiently the balance of well pumping unit piece be moved to the position that needs; do not influence job schedule, the shutdown of pumping machine time is short, and it is short good in economic efficiency to delay the production time.

Four, description of drawings

Accompanying drawing is the assembling drawing of the utility model embodiment.

Five, the specific embodiment

Below in conjunction with accompanying drawing the utility model embodiment is described.

Form by support 1, set bolt 2, oil pumping machine crank 3, sprocket wheel 4, balance of well pumping unit piece 5, set bolt 2 is fixed on the oil pumping unit reduction gearbox output shaft balance of well pumping unit piece 5, balance of well pumping unit piece 5 is adjusted to as shown in the figure position, make it be in oil pumping machine crank 3 sides, the weight of balance of well pumping unit piece 5 does not act on the oil pumping machine crank 3, can utilize own wt to move down.Set bolt 2 is through in the support 1 left end bottom hole, and support 1 is fixed on the oil pumping machine crank 3, and the fixed wheel hook of sprocket wheel 4 is suspended on the support 1, and the driving wheel of sprocket wheel 4 hangs balance of well pumping unit piece 5, does not allow balance of well pumping unit piece 5 arbitrarily drop downwards.During use, unclamp the fixedly screw of balance of well pumping unit piece 5, the operator stands in ground and easily spurs sprocket wheel balance of well pumping unit piece 5 is moved down under the self gravitation effect, and it is moved to the position that needs.
