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, and horse head one end rises still to descend all needs motor to have bigger output could drive the walking beam swing.
In addition, higher axle, the bearing portion in some positions often needs the oiling maintenance in oil pumper, and oiling is very inconvenient but the operator ascends a height.
Summary of the invention
The invention discloses a kind of oil pumper that adopts centralized lubrication, the higher position that needs oil injecting lubricating utilizes oil fuel tube can operate the oiling that hoists from ground in the position.
A kind of oil pumper that adopts centralized lubrication; 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; Be provided with oil fuel tube; One end of oil fuel tube extends near the ground, and the other end is divided into two branch roads, extends to hinged position of walking beam and bracket assembly and walking beam and the hinged position of fork respectively.
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.
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.
Described walking beam is equipped with the corresponding rotating shaft of loading ability of bearing with hinged position and the walking beam of bracket assembly with the hinged position of crossbeam, has oil filler point at the sidewall of bearing, and the termination and the oil filler point of described oil fuel tube are tightly connected.
The invention has the beneficial effects as follows through oil fuel tube and just can operate that the bearing higher to the position carries out oiling, when the higher bearing in position has when a plurality of in surface location; Oil fuel tube can be provided with corresponding branch road, guarantees that each bearing all can oiling, 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.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.
The intersection area, top of the top of second cant beam 12 and the 3rd cant beam 11 is provided with bearing, is used to carry rotating shaft 17, and walking beam 2 also is provided with bearing with the connecting portion of crossbeam 18; Be used to carry rotating shaft 4; The sidewall of these two bearings has oil filler point, is connected to oil fuel tube 19 at the oil filler point place, and oil fuel tube 19 extends downward near the ground; Be convenient to the oiling operation, during oiling oil pump inserted the bearing that oil fuel tube termination 20 can be higher with the lubrication oil injection phase.
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.
