Description

A kind of horizontal oil pumper of crank connecting link double-steel wire rope

Technical field

This utility model belongs to oil exploitation field of mechanical technique, is specifically related to that a kind of crank connecting link double-steel wire rope is horizontal takes out Oil machine.

Background technology

In oil exploitation use oil pumper be mainly beam pumping unit, it mainly by base, motor, reductor, Crank, connecting rod, walking beam, caput Equi Asini, belt form, its belt slides on cylinder thus drives pumping rod under on movement take out Oil, its good stability, but stroke is short, energy consumption big, and owing to belt is big with cylinder contact area, thus frictional force is big, and energy consumption is high, When working in the environment of sweltering heat, the easy aging deformation of belt, when working in the environment of cold, belt easily ossifys, at dust storm ratio When working in the environment of relatively big, can join and have sand, belt slip to be obstructed between belt and cylinder, in general, belt uses the longevity Ordering short, the scope of application is little.Some oil pumpers use roller structure, work, often break down in the environment of dust storm is bigger, Roller needs the most oily, and operation bothers very much.And design angle is unreasonable so that speed reducer output shaft is held The torque ratio being subject to is relatively big, increases motor power consumption.

Speed reducer base on existing oil pumper is connected by welding manner with base, due to the existence of welding stress, Making the yielding tilting in base two ends, floor installation is insecure, and during the work of such oil pumper, base easily rocks and causes safety hidden Suffer from.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of horizontal oil pumper of crank connecting link double-steel wire rope, and it is adopted Lift with double steel wire tractions, stress equalization, and crank is reasonable in design, effectively reduce the maximum torsion that speed reducer output shaft is born Square.

For achieving the above object, the technical scheme that this utility model is taked is:

A kind of horizontal oil pumper of crank connecting link double-steel wire rope, the group of motors, the reductor that including base, are arranged on base prop up Seat, the reductor installed on reductor bearing and the support being hinged on base, group of motors is with reductor by belt transmission even Connect, reductor both sides output shaft is symmetrically installed with crank body, crank body is fixed with balancing weight, the company of being hinged with on crank body Bar, is fixed with crossbeam between two interlinking lever ends, and crossbeam connects sucker rod, and described support is by two stands foreleg and two stands Back leg is constituted, and two stands foreleg bottom is hinged on base the end away from group of motors, and two stands foreleg top is fixed with installation Plate, is rotatably equipped with rotating shaft by bearing between two installing plates, rotating shaft is interval with two pulleys, at the bottom of described two stands back leg End is all hinged on reductor bearing, and two stands back leg top is hinged on the installing plate of homonymy respectively, fixing on described crossbeam Having two steel wire ropes corresponding with two pulleys, two steel wire rope one end to be fixed on crossbeam, the two steel wire rope other ends walk around phase respectively Being fixedly connected with drag link after corresponding pulley, described sucker rod is fixed in the middle part of drag link, described crank body by weight arm and Bias arm is constituted, and described balancing weight is arranged on the top of weight arm, and described connecting rod is hinged at bias arm end, weight arm and biasing Angle between arm is 69 °.

Described group of motors is made up of two motors side by side, and connecting between the output shaft of two motors has drive shaft, two motors Output shaft be all in transmission connection with drive shaft by electromagnetic clutch, the belt for assembling belt is installed in the middle part of drive shaft Wheel.

The output of described every motor is 22kw.

Described reductor bearing is connected with base by bolt, equipped with cushion in the middle of reductor bearing and base, slows down Machine is bolted on reductor bearing.

This utility model is interval with two pulleys in rotating shaft, and crossbeam is fixed with two steel wires corresponding with two pulleys Rope so that tension equalizer, stabilized structure, owing to steel wire rope is little with pulley contact area, its frictional force is little, and energy consumption is low, and steel Cord applied elongation rate is the least, and oscillating quantity is little, is not affected by environmental change, operates steadily, applied widely, weight arm and Angle between bias arm is set to 69 °, inertial load when this angle can effectively reduce machine startup and acceleration, effectively Reduce the peak torque that speed reducer output shaft is born, reduce energy consumption, cost-effective.
