The invention discloses an oil pump machine which comprises a support assembly, a motor, a speed reducer, a walking beam, a horse head, a crankshaft, a balance block and a swing rod, wherein the motor and the speed reducer are installed on the support assembly and are mutually linked; the walking beam is articulated with the support assembly through a rotary shaft; the horse head is positioned on the free oscillation end of the walking beam; the crankshaft is connected to the output shaft of the speed reducer; the balance block is fixed on the crankshaft; the swing rod is articulated between the free oscillation end of the crankshaft and the walking beam; the end head part adjacent to the horse head, of the walking beam is articulated with the swing rod; the end head far away from the horse head, of the walking beam is articulated with the support assembly through a rotary shaft; the output shaft of the speed reducer is connected with the middle part of the crankshaft; one end of the crankshaft is articulated with the swing rod; and the balance block is positioned at the other end of the crankshaft. The oil pumping machine provided by the invention has the beneficial effects that as the output shaft of the speed reducer is connected with the middle part of the crankshaft, one end of the crankshaft is articulated with the swing rod, the balance block is positioned at the other end of the crankshaft, reasonably distributed couples are formed, and energy consumption is saved to a certain extent.

Description

A kind of oil pumper

Technical field

The present invention relates to a kind of pump machinery of operation of oil field that is used for, relate in particular to a kind of oil pumper.

Background technology

Oil pumper generally comprises bracket assembly, be installed on the bracket assembly interlock each other motor and reductor, with bracket assembly through the hinged walking beam of rotating shaft, at the horse head of walking beam free pendulum moved end, be connected crank, the balance weight that is connected with crank on the speed reducer output shaft, be hinged on the fork between crank free pendulum moved end and the walking beam.

Motor drives the crank rotation through reductor, drives walking beam reciprocally swinging around the shaft through fork during the crank rotation, and the horse head of walking beam free pendulum moved end is then pumped through the traction of outstanding rope.

The fork that is used to drive walking beam in the prior art has two; One end of two contiguous walking beams of fork connects through crossbeam; Walking beam is hinged away from position, termination and this crossbeam of horse head, and bracket assembly is through being supported on rotating shaft and cooperating of bearing the middle part of walking beam, i.e. its fulcrum is positioned at the walking beam middle part during walking beam swing; One end and the fork of walking beam are hinged, and the other end is a horse head.But the walking beam type of drive energy transformation ratio that so is provided with is lower; Horse head one end rises still to descend all needs motor to have bigger output could drive the walking beam swing, and speed reducer output shaft is connected an end of crank in addition, and the other end of crank and fork are hinged; Balance weight is usually located at the middle part of crank; It is unreasonable that couple is arranged, so the layout of the selection of walking beam fulcrum and crank, balance weight all has considerable influence to the motion and the energy consumption of horse head, needs further to improve.

Summary of the invention

The invention discloses a kind of oil pumper, improved the layout of walking beam fulcrum and crank, balance weight, saved motor output, realized the reduction of energy consumption.

A kind of oil pumper; Comprise bracket assembly; Be installed on the bracket assembly interlock each other motor and reductor, and bracket assembly through the hinged walking beam of rotating shaft, at the horse head of walking beam free pendulum moved end, be connected crank on the speed reducer output shaft, be fixed on balance weight on the crank, be hinged on the fork between crank free pendulum moved end and the walking beam; The position, termination and the fork of the contiguous horse head of described walking beam are hinged, and walking beam is hinged through rotating shaft and bracket assembly away from the termination of horse head, and described speed reducer output shaft is connected with the crank middle part; One end and the fork of crank are hinged, and described balance weight is positioned at the other end of crank.

Described crank and fork all have two, the both sides that are distributed in reductor of symmetry, and an end of two contiguous walking beams of fork connects through crossbeam, and the position, termination of the contiguous horse head of described walking beam is hinged on this crossbeam through rotating shaft.

The invention has the beneficial effects as follows that speed reducer output shaft is connected with the crank middle part; One end and the fork of crank are hinged, and balance weight is positioned at the other end of crank, form the couple that rationally distributes; The fulcrum of walking beam is changed into the termination of walking beam away from horse head; When horse head descends, can only depend on its gravity to drive like this, energy consumption has been saved in only acting when horse head rises of motor to a certain extent.

Description of drawings

Fig. 1 is the structural representation of oil pumper of the present invention.

Fig. 2 is the structural representation at oil pumping machine crank of the present invention and balance weight position.

The specific embodiment

Referring to accompanying drawing, oil pumper of the present invention comprises bracket assembly, and bracket assembly comprises base 8, the triangular framing of base 8 and first cant beam 10 on it and column 9 formations.

Be provided with second cant beam 12 that extends on tiltedly at base 8 one ends; Peak at triangular framing is extended with the 3rd cant beam 11 on tiltedly; Intersect on the top of the top of second cant beam 12 and the 3rd cant beam 11, and wherein the peak of the intersection point of second cant beam 12 and base 8 and triangular framing roughly lays respectively at the two ends of base 8.

The motor and the reductor 7 of interlock are installed on the base 8 each other, and motor drives reductor through the belt pulley on the reductor 76.

Crank and fork all have two, the both sides that are distributed in reductor 7 of symmetry, combine Fig. 1,2 it is thus clear that, the output shaft 15 of reductor 7 is connected crank 5 middle parts, crank 5 one ends link to each other with fork 3, balance weight 14 is positioned at the other end of crank 5.Omitted the part crank 5 and the balance weight that are in the outside among Fig. 1, in fact every crank all fixedly is equipped with balance weight, among Fig. 1 it is thus clear that be in inboard balance weight 14.

One end of two contiguous walking beams 2 of fork connects through crossbeam 18, and the position, termination of walking beam 2 contiguous horse heads 1 is hinged on this crossbeam 18 through rotating shaft 4.Walking beam 2 is hinged away from the intersection area on the top of the termination of horse head 1 top and the 3rd cant beam 11 through the rotating shaft 17 and second cant beam 12.

For the ease of ascend operation, be distributed with ladder 13 along second cant beam 12.Periphery at base 8 is provided with safety barrier 16.

During oil pumper of the present invention work, motor drives cranks 5 rotations through reductor 7, and the movement locus of the termination that crank 5 is connected with fork 3 can be referring to the circle of the B among the figure, can be round referring to the A in scheming and be in the movement locus of outer rim of the balance weight 14 of crank 5 other ends.

Crank 5 rotations drive fork 3, drive the position, termination of walking beam 2 contiguous horse heads 1 then, make walking beam 2 17 reciprocally swingings around the shaft.

Because rotating shaft 17 is positioned at the termination position of walking beam 2 away from horse head 1, horse head 1 can only depend on its gravity to drive when descending, and motor is acting when horse head 1 rises only, has saved energy consumption.
