Abstract
The utility model belongs to the field of oil-extraction mechanical equipment of an oil field, and in particular relates to an equalizing-beam mobile counter weight type energy-saving oil pumping unit. The equalizing-beam mobile counter weight type energy-saving oil pumping unit comprises a support, a walking beam, a horse head and an oil pumping rod, wherein the walking beam is mounted at the top of the support through a support shaft; the horse head is fixed to the front end of the front arm of the walking beam; the horse head is connected to a beam hanger through a lifting rope; a front counter weight and a rear counter weight both capable of sliding along the walking beam synchronously are mounted on the front beam and the rear arm of the walking beam, respectively; the front counter weight and the rear counter weight are connected to a traction device; and the front arm of the walking arm is shorter than the rear arm. The oil pumping unit is simple in structure because a high power motor, a reducer, a link, a crankshaft and the like of the traditional walking beam type oil pumping unit are saved; the front and rear counter weights are driven by the low power traction device to move in the same direction at a short distance synchronously; the level principle is fully utilized; and simultaneous movement of the front and rear counter weights upsets the balance quickly and provides power for the up-and-down movement of the oil pumping unit; therefore, the energy is saved and the consumption is reduced, and the operation is steady; and stop intermittent oil pumping can be realized.
Description
Technical field
The utility model relates to a kind of equalizer bar mobile counterweight formula energy-saving pumping unit, belongs to oil field oil recovery machiner apparatus field.
Background technology
Traditional beam pumping unit drives balancing weight by the motor deceleration device and does rotation and move back and forth, and the pulling walking beam makes horse head constantly move up and down (being up-down stroke); When upstroke, motor and balancing weight need overcome the acting of oil pumping load, when down stroke; Horse head and oil rig descend rapidly, and at this moment, the motor actual speed can surpass synchronous rotational speed; Motor is in generating state, and because balance weight is done the motion of round mark, when the balance weight phase angle hour; The merit that motor is done is an idle work basically, and energy consumption is big.Oil pumper running is uneven, and not only needing provide big power with big motor, and influence electric efficiency, makes the power factor reduction of motor, and the expanded motor power attenuation reduces life-span of motor.
The utility model content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: provide that a kind of drive disk assembly is few, running steadily, energy-saving and cost-reducing and can shut down the equalizer bar mobile counterweight formula energy-saving pumping unit that is interrupted oil pumping.
The utility model solves the technical scheme that its technical problem adopted: described equalizer bar mobile counterweight formula energy-saving pumping unit; Comprise support, walking beam, horse head and sucker rod; Walking beam is installed in the top of support through back shaft; Horse head is fixed on the front end of walking beam forearm, and horse head links to each other with polished rod eye through lifting rope, it is characterized in that: the front-end weight block and back balancing weight that slide synchronously along walking beam are installed respectively on the forearm of walking beam and the postbrachium; Front-end weight block is connected draw-gear with the back balancing weight, and the forearm length of walking beam is less than the back arm lengths.
Be fixed with limited block on the described walking beam, limited block is distributed in the both sides of front-end weight block and back balancing weight.
Drive forward and backward balancing weight through draw-gear and make synchronous equidirectional small distance movement, thus the front and back weight of adjustment walking beam, and the control walking beam moves up and down, and then pulling sucker rod, oil well pump move up and down, and realizes maximized pumping efficiency with minimum power.Utilize lever balance theory, forward and backward balancing weight slides synchronously, can not only disequilibrate fast, and forward and backward balancing weight increases one at one of walking beam two arm top offsets and subtracts and can power be provided for moving up and down of oil pumper.
Wherein, described draw-gear can be hoist engine, hydraulic motor or hydraulic jack, and the draw-gear startup is frequency conversion soft start.When balancing weight is subjected to displacement, draw-gear operation work done, the balancing weight stroke stops then stopping acting; Therefore draw-gear is when accomplishing a complete oil pumping jig frequency; Half the time is in operation acting state, and second half time is in stopped status, can realize shutting down and be interrupted oil pumping; Be frequency conversion soft start because draw-gear starts, the oil pumping jig frequency can be set arbitrarily, adjust; The speed of up-down stroke can be set, adjust through the displacement of adjustment balancing weight.
The beneficial effect that the utility model had is:
This oil pumper is simple in structure; Heavy-duty motor, reductor and connecting rod, bent axle of traditional beam pumping unit etc. have been saved; Drive the synchronous equidirectional small distance movement of forward and backward balancing weight through the small-power draw-gear, made full use of lever balance theory, and can disequilibrate fast through forward and backward counterweight simultaneous displacement; And power is provided for moving up and down of oil pumper, energy-saving and cost-reducing and operate steadily; Draw-gear is when accomplishing a complete oil pumping jig frequency, and half the time is in operation acting state, and second half time is in stopped status, can realize shutting down and be interrupted oil pumping.

Among the figure: 1, back balancing weight; 2, limited block; 3, walking beam; 4, draw-gear; 5, back shaft; 6, front-end weight block; 7, horse head; 8, lifting rope; 9, polished rod eye; 10, support.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1, equalizer bar mobile counterweight formula energy-saving pumping unit comprises support 10, walking beam 3, horse head 7 and sucker rod; Walking beam 3 is installed in the top of support 10 through back shaft 5; Horse head 7 is fixed on the front end of walking beam 3 forearms, and horse head 7 links to each other with polished rod eye 9 through lifting rope 8, and the front-end weight block 6 and back balancing weight 1 that slide synchronously along walking beam 3 are installed respectively on the forearm of walking beam 3 and the postbrachium; Front-end weight block 6 is connected draw-gear 4 with back balancing weight 1; The forearm length of walking beam 3 also is fixed with limited block 2 less than the back arm lengths on the walking beam 3, limited block 2 is distributed in the both sides of front-end weight block 6 and back balancing weight 1.
Drive forward and backward balancing weight 1 through draw-gear 4 and make synchronous equidirectional small distance movement; Thereby the front and back weight of adjustment walking beam 3; Control walking beam 3 moves up and down, and then pulling sucker rod, oil well pump move up and down, and realizes maximized pumping efficiency with minimum power.Draw-gear 4 can be hoist engine, hydraulic motor or hydraulic jack, and draw-gear 4 startups are frequency conversion soft start.When balancing weight is subjected to displacement, draw-gear 4 operation works done, the balancing weight stroke stops then stopping acting; Therefore draw-gear 4 is when accomplishing a complete oil pumping jig frequency; Half the time is in operation acting state, and second half time is in stopped status, can realize shutting down and be interrupted oil pumping; Be frequency conversion soft start because draw-gear 4 starts, the oil pumping jig frequency can be set arbitrarily, adjust; The speed of up-down stroke can be set, adjust through the displacement of adjustment balancing weight.
