Abstract
The utility model relates to a novel crank balancing walking-beam oil pumping unit. The technical scheme includes that the novel crank balancing walking-beam oil pumping unit comprises a connecting rod, a connecting rod support, an inclined support, a crankshaft and a middle supporting rod, a supporting frame is fixed on one side of a base, the inclined support is mounted on the other side of the base, the middle supporting rod is mounted between the supporting frame and the inclined support, both the supporting frame and the inclined support are fixed together with the top of the middle supporting rod connected with one end of a walking beam through a walking beam support, a horse head is fixed at the other end of the walking beam and connected with a beam hanger through a lifting rope, the connecting rod is mounted between the crank balancing block and the walking beam, and the upper end of the connecting rod is connected with the walking beam while the lower end of the same is connected to a crankshaft of the crank balancing block. The novel crank balancing walking-beam oil pumping unit has the advantages that a motor transmits high-speed rotating motion to a speed reducing box through a belt, a crank connecting rod mechanism formed by the connecting rod support, the walking beam and the inclined support converts rotating motion into up-down swinging of the walking beam, and the beam hanger hung on the horse head drives an oil pumping rod below to realize oil pumping; the oil pumping unit is novel in structure and low in energy consumption, so that oil extraction cost is lowered.
Description
Technical field
The utility model relates to a kind of oil pumper, particularly a kind of novel crank balance beam type oil pump.
Background technology
At present, in mechanical oil recovery lifting means, widely used is conventional beam-pumping unit, and its quantity accounts for the more than 80% of oil recovery lifting means.It has advantages of that reliability is high and the life-span is long, but also has the shortcoming that power consumption is large and consumptive material is many.Beam pumping unit is comprised of motor, reduction box, crank-link mechanism, walking beam, support, horse head, steel cable and polished rod eye.The balance of beam pumping unit is mainly that the balancing weight by being arranged on crank and walking beam is realized, and motor, for reductor provides power, drives crank-link mechanism operation, and the balancing weight on crank also rotates thereupon.Balance weight weight is large, not only increases manufacturing cost, in running energy consumption large, improved oil recovery cost of production.Balance weight is cylinder iron made, and every machine will be joined four.In the oil pumper course of work, down-hole load change is very large, and load change is frequent, causes walking beam two ends moment unbalance, and motor load is inhomogeneous, and mesh power is large, thereby energy consumption is high.The movement parts of oil pumper is as also very large in consumed in the motion processes such as horse head, walking beam.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of novel crank balance beam type oil pump is provided.
Its technical scheme is: comprise polished rod eye, lifting rope, horse head, walking beam, walking beam bearing, bracing frame, motor, crankshaft balance weight and base, also comprise connecting rod, connecting rod support, tilted supporter, crank axle and middle support rod, described bracing frame is fixed on a side of base, the opposite side of base is installed tilted supporter, between bracing frame and tilted supporter, install middle support rod, the top of bracing frame and tilted supporter and middle support rod is fixed together, and by one end of walking beam bearing connection walking beam, the other end of walking beam is horse head fixedly, and horse head connects polished rod eye by lifting rope; Installing connecting rods between crankshaft balance weight and walking beam, the upper end of connecting rod connects walking beam, and lower end is connected to the crank axle of crankshaft balance weight.
Between above-mentioned tilted supporter and middle support rod, fixed bar is installed.
The front end of above-mentioned crankshaft balance weight is provided with balance weight, and rear end is by connecting rod connecting crank axle, and middle part connects reduction box, and reduction box is connected with the output shaft of motor.
The beneficial effects of the utility model are: motor passes to reduction box by belt by rotatablely moving of high speed, the crank-link mechanism being comprised of connecting rod support, walking beam, tilted supporter is again converted into swinging up and down of walking beam by rotatablely moving, the polished rod eye hanging on horse head drives sucker rod below to realize oil pumping; Its novel structure, energy consumption is low, has reduced cost for oil production.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: polished rod eye 1, lifting rope 2, connecting rod 3, horse head 4, connecting rod support 5, walking beam 6, tilted supporter 7, walking beam bearing 8, bracing frame 9, motor 10, crankshaft balance weight 11, base 12, crank axle 13, middle support rod 14, fixed bar 15.
The specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises polished rod eye 1, lifting rope 2, horse head 4, walking beam 6, walking beam bearing 8, bracing frame 9, motor 10, crankshaft balance weight 11 and base 12, in addition, also comprise connecting rod 3, connecting rod support 5, tilted supporter 7, crank axle 13 and middle support rod 14, described bracing frame 9 is fixed on a side of base 12, the opposite side of base 12 is installed tilted supporter 7, between bracing frame 9 and tilted supporter 7, install middle support rod 14, the top of bracing frame 9 and tilted supporter 7 and middle support rod 14 is fixed together, and by one end of walking beam bearing 8 connection walking beams 6, the other end of walking beam 6 is horse head 4 fixedly, horse head connects polished rod eye 1 by lifting rope 2, installing connecting rods 3 between crankshaft balance weight 11 and walking beam 6, the upper end of connecting rod 3 connects walking beam 6, and lower end is connected to the crank axle 13 of crankshaft balance weight 11.
Wherein, between tilted supporter 7 and middle support rod 14, fixed bar 15 is installed, the front end of above-mentioned crankshaft balance weight 11 is provided with balance weight, rear end is by connecting rod connecting crank axle 13, middle part connects reduction box, and reduction box is connected with the output shaft of motor 10, because motor, reduction box and crankshaft balance weight are positioned at the center of base, its vibration is little, noise is low, long service life.
During work, motor 10 passes to reduction box by belt by rotatablely moving of high speed, the crank-link mechanism being comprised of connecting rod support 5, walking beam 6, tilted supporter 7 is again converted into swinging up and down of walking beam by rotatablely moving, the polished rod eye hanging on horse head drives sucker rod below to realize oil pumping.
