Description
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; Therefore, the selection of walking beam position of the fulcrum, and the structure of bracket assembly awaits to improve.
Summary of the invention
The invention discloses a kind of oil pumper that improves bracket assembly, improve, realized the reduction of energy consumption through walking beam position of the fulcrum and bracket assembly.
A kind of oil pumper that improves bracket assembly; 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; Described bracket assembly comprises base; Be positioned on the base and constitute first cant beam and the column of triangular framing with base; Be provided with second cant beam that extends on tiltedly at base one end, on tiltedly, be extended with the 3rd cant beam at the peak of triangular framing, the top of the top of second cant beam and the 3rd cant beam is crossing; Wherein the peak of the intersection point of second cant beam and base and triangular framing lays respectively at the two ends of base, and described walking beam is hinged on second cant beam and the crossing position of the 3rd cant beam.
The position, termination and the fork of the contiguous horse head of described walking beam are hinged, and walking beam is hinged on second cant beam and the crossing position of the 3rd cant beam away from the termination of horse head through rotating shaft.
Described first cant beam, column, second cant beam and the 3rd cant beam are two and be symmetrically distributed in the base both sides; Wherein be connected through second crossbeam between the crossing position of second cant beam of second cant beam of a side and the 3rd cant beam position of intersecting and opposite side and the 3rd cant beam, described walking beam is hinged on second crossbeam through rotating shaft away from the termination of horse head.
Base, first cant beam and column constitute triangular framing, and second cant beam, the 3rd cant beam and first cant beam have also constituted similar triangular framing, and the double triangle framework makes and is difficult for the bracket assembly good stability rocking.
Because first cant beam, column, second cant beam and the 3rd cant beam are two and be symmetrically distributed in the base both sides, so all there is described double triangle frame the both sides of base.
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 bracket assembly has adopted two triangular frame structures, good stability is difficult for rocking.In addition 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.
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, visible crank 5 is connected with the output shaft 15 of reductor 7 among the figure, and 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, among the figure 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.
Base 8, first cant beam 10 and column 9 constitute triangular framings, and second cant beam 12, the 3rd cant beam 11 and first cant beam 10 have also constituted similar triangular framing, and the double triangle framework makes and is difficult for the bracket assembly good stability rocking.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.
