Abstract
The utility model discloses an energy-saving oil pumping unit, which comprises a bracket assembly, a motor, a speed reducer, a walking beam, a horse head, a crank, a balance weight and a swing link, wherein the motor and the speed reducer are arranged on the bracket assembly and are linked with each other; the walking beam is hinged with the bracket assembly through a rotating shaft; the horse head is positioned at the free swing end of the walking beam; the crank is connected to an output shaft of the speed reducer; the balance weight is fixed on the crank; the swing link is hinged between the free swing end of the crank and the walking beam; the end head part of the walking beam close to the horse head is hinged with the swing link; and the end head of the walking beam away from the horse head is hinged with the bracket assembly through the rotating shaft. The oil pumping unit has the beneficial effects that: a supporting point of the walking beam is changed at the end head of the walking beam away from the horse head, so that the horse head can be only driven by the gravity of the horse head to drop; the motor only does work during lifting of the horse head; and the energy consumption is saved to a certain extent.
Description
Technical field
The utility model relates to a kind of pump machinery of operation of oil field that is used for, and relates in particular to a kind of oil pumper.
Background technology
Oil pumper generally comprises bracket assembly, be installed on the bracket assembly motor of interlock mutually and reductor, with bracket assembly by 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 by reductor, drives walking beam reciprocally swinging around the shaft by fork during the crank rotation, and the horse head of walking beam free pendulum moved end is then pumped by 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 by crossbeam, walking beam is hinged away from position, termination and this crossbeam of horse head, and bracket assembly is supported on the middle part of walking beam by rotating shaft and cooperating of bearing, its fulcrum is positioned at the walking beam middle part when being the walking beam swing, one end and the fork of walking beam are hinged, and the other end is a horse head.But so the walking beam type of drive energy transformation ratio that is provided with is lower, and horse head one end rises still to descend all needs motor to have bigger output could drive the walking beam swing.
The utility model content
The utility model discloses a kind of oil pumper that improves the walking beam type of drive, when horse head descends, only utilize himself gravity, saved the output of part motor, realized the reduction of energy consumption.
A kind of oil pumper of energy-saving type, comprise bracket assembly, be installed on the bracket assembly motor of interlock mutually and reductor, and bracket assembly by 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 by rotating shaft and bracket assembly away from the termination of horse head.
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 by crossbeam, and the position, termination of the contiguous horse head of described walking beam is hinged on this crossbeam by rotating shaft.
The beneficial effects of the utility model are that the fulcrum of walking beam is changed into the termination of walking beam away from horse head, can only depend on its gravity to drive like this when horse head descends, and 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 the oil pumper of a kind of energy-saving type of the utility model.
The specific embodiment
Referring to accompanying drawing, the oil pumper of a kind of energy-saving type of the utility model comprises bracket assembly, and bracket assembly comprises base 8, the triangular framing that base 8 and first cant beam 10 on it and column 9 constitute.
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 mutually, and motor drives reductor by the belt pulley on the reductor 76.
Crank and fork all have two, the both sides that are distributed in reductor 7 of symmetry, visible crank 5 is connected with the output shaft 15 of reductor 7 among the figure, crank 5 one ends link to each other with fork 3, the other end is equipped with balance weight, omitted the part crank 5 and the balance weight that are in the outside among the figure, in fact every crank all fixedly is equipped with balance weight, as seen is in inboard balance weight 14 among the figure.
One end of two contiguous walking beams 2 of fork connects by crossbeam 18, and the position, termination of walking beam 2 contiguous horse heads 1 is hinged on this crossbeam 18 by rotating shaft 4.Walking beam 2 is hinged away from the top and the intersection area on the top of the 3rd cant beam 11 by the rotating shaft 17 and second cant beam 12, the termination of horse head 1.
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 the work of the utility model oil pumper, motor drives crank 5 rotations by reductor 7, the movement locus of the termination that crank 5 is connected with fork 3 can be referring to the B among figure circle, can be referring to the circle of the A among the figure and be in the movement locus of outer rim of the balance weight 14 of crank 5 other ends.
Crank 5 rotating band movable pendulum bars 3 drive the position, termination that walking beam 2 is close to 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.
