Abstract
The utility model relates to a novel adjustable balancing type walking-beam oil pumping unit. The technical scheme includes that a supporting frame is fixed on one side of a base, an inclined support is mounted on the other side of the base, a 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 and connected with the middle of a walking beam through a walking beam support, a horse head is fixed at the front end of the walking beam, the rear end of the walking beam is connected with an adjustable balancing block, sand is filled in the adjustable balancing block, the horse head is connected with a beam hanger through a lifting rope, a connecting rod is mounted between a 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 adjustable balancing type walking-beam oil pumping unit has the advantages that a crank connecting rod mechanism formed by a connecting rod support, the walking beam and the inclined support converts rotating motion into up-down swinging of the walking beam, and the sand is filled inside the adjustable balancing block, so that accurate matching can be realized; 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 adjustable balanced type beam pumping unit.
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, and every all very heavy, is still difficult in use reach accurate coupling.
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 adjustable balanced type beam pumping unit 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 the middle part of walking beam bearing connection walking beam, the front end of walking beam is horse head fixedly, the rear end of walking beam connects adjustable balancing block, sand is housed in adjustable balancing block, 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.
The top of above-mentioned adjustable balancing block is provided with upper cover, and upper cover is provided with switch.
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; And the adjustable balancing piece adopting, sand is equipped with in inside, can realize accurate coupling, and its novel structure, and 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, adjustable balancing block 16, switch 17.
The specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
