Five, the specific embodiment
The present invention is not subjected to the restriction of following embodiment, can determine concrete embodiment according to technical scheme of the present invention and actual conditions.
Below in conjunction with embodiment and accompanying drawing the present invention is further described:
As shown in Figure 1, this automatic torque-changing pumping unit comprises motor 1, reducer 3, crank 4, connecting rod 6, support 7, balance weight device 9, walking beam 13, horse head 14, flexible piece 15, polished rod 16 and base 17, motor 1, reducer 3 and support 7 are fixedly mounted on the base 17, walking beam 13 middle parts are hinged on the top of support 7, walking beam 13 front ends are fixed with horse head 14, the middle part of variable torque balance beam 10 is hinged on the rear end of walking beam 13, the rear end of variable torque balance beam 10 is equipped with balance weight device 9, the upper end of flexible piece 15 is fixedly mounted on the front end of variable torque balance beam 10, the lower end of flexible piece 15 is fixedly mounted on the polished rod 16, and the middle part of flexible piece 15 rides on the horse head 14 and can slide on horse head 14.
Can according to actual needs last the present invention be made further optimization and/or improvements:
As shown in Figure 1, flexible piece 15 adopts flexible strand or flexible band or flexible chain; Balance weight device 9 can adopt fixed, and it can be fixed counterweight gauge block or fixed counterweight post; In order to increase compliance, balance weight device 9 preferably adopts movable, and this balance weight device 9 can comprise balance weight body and balance weight, is useful on the cavity of placing balance weight on balance weight body; The middle part of variable torque balance beam 10 is hinged on the rear end of walking beam 13 by hinged-support 11.
Above technical characterictic has constituted most preferred embodiment of the present invention, and it has stronger compliance and best implementation result, can increase and decrease non-essential technical characterictic according to actual needs, satisfies the demand of different situations.
The course of work of most preferred embodiment of the present invention is as follows: as shown in Figure 1, motor 1 rotates by the crank 4 that V belt 2 drives on the reducer 3, and by crank-pin 5, connecting rod 6 and crossbeam bearing support 8 traction walking beams 13 and horse head 14 swings, drive polished rod 16 and sucker rod work rectilinear motion up and down reciprocatingly by horse head 14 again, drive the oil well pump oil pumping.
In automatic torque-changing pumping unit operation process of the present invention, when the load on the polished rod 16 increases, the power that flexible piece 15 is added on the variable torque balance beam 10 will increase, will break variable torque balance beam 10 original equilibrium states like this, make variable torque balance beam 10 angle that turns clockwise, balance weight device 9 becomes big to the distance at axis of centres bearing 12 centers, it is big that thereby the balance arm of force becomes, make oil pumper reach a new equilibrium state, simultaneously, because variable torque balance beam 10 angle that turns clockwise, flexible piece 15 along the cambered surface of horse head 14 to distance of lower slider, with pushing the speed and amplitude of buffering polished rod 16 load.
When the load on the polished rod 16 reduces, the power that flexible piece 15 is added on the variable torque balance beam 10 will reduce, so also can break variable torque balance beam 10 original equilibrium states, make variable torque balance beam 10 be rotated counterclockwise an angle, balance weight device 9 diminishes to the distance at axis of centres bearing 12 centers, thereby the balance arm of force diminishes, make oil pumper reach a new equilibrium state, simultaneously, because variable torque balance beam 10 is rotated counterclockwise an angle, flexible piece 15 is in the cambered surface of horse head 14 distance of upwards sliding, and reduces speed and amplitude with the buffering PRL.
Zong the above, when automatic torque-changing pumping unit Yun Zhuan of the present invention, the Zeng of polished rod 16 Zai lotuses the little bending moment that just can make that adds deduct is flat 10 rich hinged-support 11 rotations of weighing apparatus beam, the position of change balance weight device 9, it is little that balance arm of force Zeng is added deduct, and it is flat to reach change The effect of weighing apparatus moment, maximum limit degree ground balance polished rod 16 Zai lotuses. Simultaneously, the Zhuan of You Yu variable torque balance beam 10 is moving, so that the present invention Automatic torque-changing pumping unit has certain software feature, can You the buffering automatic torque-changing pumping unit of the present invention of effect when starting and Yun Zhuan mistake The pump rapid variation of airborne lotus of journey Zhong reducing the oil pumper starting current and to reduce the stressed of parts, thereby realizes energy-conservation and prolongs The effect of long life.
