Description

Rotating head sheave oil pumper

Technical field:

The utility model belongs to the oil exploration equipment technical field, relates to a kind of improvement of oil pumper.

Background technology:

At present, in the oil exploitation at home and abroad, use beam pumping unit widely, be characterized in simple in structure, arranged higher application life, but because of its design feature, determined to exist the shortcoming that is difficult to overcome, as be difficult to realize the production demand of the big discharge capacity of long stroke, its counterweight is difficult to adjust to such an extent that mate with suspending point loading, make motor-driven year of walking beam excessive, work operational system disequilibrium wastes energy; In order to improve output, strengthen jig frequency quantity, impel critical pieces such as oil pumper and pump extension system to produce fatigue failure and inefficacy prematurely, the possessor transforms the walking beam machine to the greatest extent, above-mentioned shortcoming still is difficult to overcome, DeGrain, so people think that at large the walking beam machine is the oil pumper that efficient is low, energy consumption is high.

For adapting to the development of petroleum industry, many kinds of long stroke pumping units have been developed again, as types such as chain type oil pump, orthoscopic oil pumper, long stroke pumping units, though overcome the existing shortcoming of walking beam machine preferably, but these types have brought complex structure, fault rate height again, have faced the big problem of telephone-moving when also all existing workover treatment, after the complete machine telephone-moving resets, just are being difficult to again, this can cause oil pumper unbalance loading aggravation oil pumper to damage, and causes very big loss to Petroleum Production.

Summary of the invention:

Technical problem to be solved in the utility model is:

A kind of telephone-moving on the spot, long stroke rotating head sheave oil pumper simple in structure are provided.

The technical solution of the utility model is as follows:

Motor, yielding coupling, reductor, head sheave, positive and negative driving wheel, the holder that positive and negative driven pulley is formed is moving, the transmission workpiece, all be fixed on the pivoting support, and be fixed on the frame by turning down supporting base supporting, motor connects yielding coupling, its output is connected on the brake disc end face of reductor power shaft, on the external diameter of brake disc brake is installed, speed reducer output shaft is equipped with the rotating driving wheel, reductor be fixed on the crown sheave bearing and with crown sheave in stud with the rotating driven pulley and be meshed, crown sheave is by two gardens awl roller bearings and overhead traveling crane axle bearing.

Motor can adopt frequency conversion reversing motor, switch magnetic group motor, brushless buncher, dc speed-regulating motor.

Reductor can adopt planetary reducer, cycloidal planetary gear speed reducer, garden stud wheel reductor.

Rubbing property connected body can adopt belt of wire rope, polyurethane adhesive tape, profile of tooth adhesive tape.

With external tooth engagement, external tooth engagement, outer and external tooth engagement or pin and pin wheel mesh form, its speed ratio was in 1: 30 scope in engagement between rotating driving wheel and rotating driven pulley was adopted.

Pivoting support is equipped with the moving system of reductor revolution holder of band micro machine in the telephone-moving mechanism, drive initiatively gyroscope wheel and the turning down supporting base that studs with driven gyroscope wheel composition, under the driving of the moving system of revolution holder, last revolution is bearing in rotatable moving on the turning down supporting base, and active and driven gyroscope wheel are pin and pin wheel transmission.

The beneficial effects of the utility model are:

Realized simple in structure, mechanical efficiency height (more than 55%), reliable operation, output torque is big, degree of balance configuration coefficients height (more than 98%), starting current is little, with same type machine walking beam machine ratio, economize on electricity is more than 30%, the polytype motor be can select for use, long stroke, big discharge capacity realized, because of having changed the horizontal moment direction of transfer of long stroke pumping unit, the direction of transmitting is a vertical direction, so stable working; During workover treatment, start the moving system of revolution holder, realized automatic telephone-moving, self-return, operation is simple and reliable for it, and complete machine moves hard work when having substituted the oil field well workover.
