Wherein, be respectively arranged with two front suspender belt cannelures and two back strap cannelures on reel 21 peripheries, before each, the suspender belt cannelure all is fixedly connected with an end of a front suspender belt 9, and each back strap cannelure all is fixedly connected with an end of a back strap 5; Rear guide wheel 6 is the two-wheel groove, is complementary with two back straps 5 respectively, and the pulley 31 on front jocket wheel 7, the pulley 37 on semi girder 8 is the two-wheel groove, is complementary with two front suspender belts 9 respectively.Two front suspender belts 9 are left-handed to be wrapped in the front suspender belt cannelure 51 of two inboards, and two back strap 5 dextrorotation are wrapped in the back strap cannelure 50 in two outsides, and front suspender belt 9 and back strap 11 reverse-windings are on reel 21.
During work, motor 13 starts, and band movable reel 21 rolls, and then drives the oil pumper motion.The commutation of oil pumper is that the conversion by motor 13 electric currents reaches.When the needs oil pumper was stepped down, front suspender belt 9 broke away from from polished rod eye 10, and the crawl oil pumper makes the front suspender belt head on front suspender belt 9 slowly up, and semi girder is overturn around bearing, reached the oil pumper operation requirement of stepping down.
At first, the required starting torque of the invention oil pumper is little.Required starting torque size during startup determines required consumed power size.The oil pumper motion process is that the upstroke bottom dead centre starts, and------the upstroke top dead-centre slows down, and---the down stroke top dead-centre accelerates---middle uniform motion---down stroke bottom dead centre and slows down middle uniform motion.Upper bottom dead centre is all given long acceleration time.
When upstroke starts, the frequency temporal evolution of control circuit and at the uniform velocity strengthening, the rotating speed of motor is also accelerated with power frequency, and quilt is at this moment dragged primer also in even acceleration.Power frequency is just can reach the required stabilized frequency of oil pumper after after a while, and this section period is also dragged the even accelerating sections of primer.This moment is single from the motor aspect, has eliminated part and has been dragged the required energy consumption of primer momentum conversion.If allow motor locate at the uniform velocity under state always, being dragged the required power of primer momentum change will be very large, and electric current must also can be very large, and the motor in-fighting must increase; Must lengthen the acceleration time in order to reduce this in-fighting, must slow down in a segment distance of before top dead center, otherwise, can not make oil pumper drag primer when upper dead center position and stop moving upward.Therefore, dragged primer arrive upper dead center position distance the last period must even deceleration, also just need the frequency step-down gradually of the electric current of institute's power supply machine, motor movement is negative acceleration, so that speed is zero when being dragged primer to upper dead center position.During down stroke, after oil pumper, counterweight part is heavy.The upstroke operating mode of oil pumper be polished rod load subtract the counterweight gravity value on the occasion of, during down stroke, to subtract the counterweight gravity value be negative value to polished rod load, it is elimination power value difference that oil pumper power does work.That is to say motor in the action that repeats the oil pumper upstroke, required electric current reduces, so it is energy-conservation on the one hand for this.
Another energy-conservation reason is: reel 21 is realized reducing by being wound around suspender belt.As Fig. 5-Fig. 8, during upstroke, twining on the race of winding back strap 5 has expired suspender belt, and on the race of the front suspender belt 9 of winding, suspender belt is all emitted; Cause the wheel footpath of suspender belt wheel before and after being wound around this moment not waited, rear counterweight is large to the arm of force of bottom main shaft effect, and the front end PRL is less to the arm of force of bottom main shaft effect, has therefore dwindled the difference in torque that front end PRL and rear counterweight produce main shaft; Also just reduced the moment of torsion that reducer need to be exported, reduced current of electric and changed the in-fighting that produces.During down stroke, twining on the race of suspender belt before being wound around has expired suspender belt, and on the race of winding back strap, suspender belt is all emitted; Cause the wheel footpath of suspender belt wheel before and after being wound around this moment not waited, rear counterweight is little to the arm of force of bottom main shaft effect, and the front end PRL is larger to the arm of force of bottom main shaft effect; At this moment, also dwindled front end PRL and rear counterweight to the difference in torque that main shaft produces, also just reduced the moment of torsion that reducer need to be exported, reduced current of electric and changed the in-fighting that produces.Repeated conversely the operating mode of top dead-centre.Upper bottom dead centre has all reduced the required electric current of motor, so be energy-conservation.
The above, it is only the preferred embodiment of the invention, be not that any pro forma restriction is done in the invention, any those skilled in the art, within not breaking away from the invention technical scheme scope, according to the technical spirit of the invention to any simple modification made for any of the above embodiments, equivalent variations and modification, as being only the common variation of the concrete structure of dynamical system, guiding lubricating box, reel, directive wheel, all still belong in the scope of the invention technical scheme.
