Background technology
At present, the ground installation of oil extraction in oil field mainly is petroleum extractor, the oil pumper of using the crank balance structure accounts for about 80%, oil pressure and oil mass variation because of oil in place, for energy-conservation and raising oil yield, need to adjust crank balance according to working conditions change, drive motors ascending current and centrifugal current balanced ratio are maintained between the 80%-120%, therefore adjusting balance weight is regular work in the oil recovery management.Execute-in-place is finished by hand by three people at least; when the balanced ratio of the ascending current of the petroleum extractor motor of measuring and centrifugal current departs from when larger; shut down and adjust, first crank is adjusted at horizontal level, unclamp the nut at the set bolt place at balance weight two ends; and take off the side lock dog; at crank both sides rollings dynamic balance weight, and from the end crowbar mobile balanced block of crank, rule of thumb the adjustment position of definite balance weight; adjust and finish rear locking lock dog and nut, restart at last oil pumper.Such adjustment process needs 1-2 hour; shut down when adjusting; variation has occured in oil pressure and oil mass in the pumping pipelines; when restarting oil pumper work after adjustment finishes, approximately need 12-24 hour ability to recover steady working condition, because according to the definite adjustment distance of experience; and it is unknown in real time to adjust effect; after steady working condition, just can measure, if the deviation of still having need repeat above-mentioned adjustment process again.The method labor strength is large, and length consuming time need to operate under the state of shutting down, and affects oil well output and oil recovery efficiency, and very large sense datum is arranged in the adjustment process, is difficult to guarantee precision and the effect of adjustment.Therefore, the adjusting device of accurate adjustment has stronger application demand not shutting down in real time automatically in employing.
The utility model content
In order to overcome the prior art above shortcomings; the utility model provides the automatic regulating apparatus of a kind of petroleum extractor balance weight position; this utility model is adjusted the position of counter weight of beam unit automatically under non-stop-machine condition, save manpower and time, and it is high to adjust precision.
The technical scheme that its technical problem that solves the utility model adopts is: the automatic regulating apparatus of a kind of petroleum extractor balance weight position comprises operational order input module, position control module, servo-driven module, encoder, motor and flange.Described operational order input module on-position control module, the output signal on-position control module of encoder, position control module access servo-driven module, servo-driven module access motor, the output shaft of motor connects with the worm screw input of worm and gear speed-reduction apparatus, encoder and motor coaxle are installed in the non-input of worm screw, and the end of leading screw connects firmly by flange and balance weight.
Described worm and gear speed-reduction apparatus is fixed on an end of crank by junction plate, adopt the mode that is slidingly connected between crank and the balance weight.
The beneficial effects of the utility model are: use this device to regulate and shortened the adjustment time, improved the adjustment precision.Because adjustment process is not shut down, and has improved pumping efficiency and motor unit power consumption oil pump capacity, and the effect of energy efficiency is arranged.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is done further specific description.
Embodiment
Fig. 1 is the automatic regulating apparatus of the disclosed petroleum extractor balance weight of the utility model position, and described device comprises operational order input module 12, position control module 11, servo-driven module 10, encoder 1, motor 9 and flange 4.Operational order input module 12 on-position control modules 11, the output signal access on-position control module 11 of encoder 1, position control module 11 access servo-driven modules 10, servo-driven module 10 access motors 9, the output shaft of motor 9 connects with worm screw 13 inputs of worm and gear speed-reduction apparatus 2, encoder 1 and the motor 10 coaxial non-inputs that are installed in worm screw 13, the end of leading screw 3 connects firmly by flange 4 and balance weight 7.Described worm and gear speed-reduction apparatus 2 is fixed on an end of crank 6 by junction plate 8, adopt the mode that is slidingly connected between crank 6 and the balance weight 7.
The upper and lower end face of crank 6 has "T"-shaped groove, the end processing boss of balance weight 7, the "T"-shaped groove of crank 6 matches with the boss of balance weight 7, and with flat head screw 15 catch 14 is fixed on the boss of balance weight 7, makes between crank 6 and the balance weight 7 and can only endwisely slip.
Operating principle of the present utility model is: the average of current of electric is called up average current in the up process of beam-pumping unit sucker rod, the average of current of electric is called descending average current in the descending process, the ratio of up average current and descending average current is called balanced ratio, balanced ratio motor near 100% time operates steadily oil pump energy-saving.Balance weight 7 required amount of movement and the moving directions that calculate according to the balanced ratio of ascending current and centrifugal current, by the operation input module 12 with move input position control module 11 after, rotate through servo-driven module 10 control motors 9 again, motor 9 according to target displacement is made the actions such as forward or reverse, then, drive worm and gear speed-reduction apparatus 2 by motor 9, the screw-nut body that forms by worm gear and screw mandrel drives leading screw 3 realization push pull maneuver.Leading screw 3 is connected on the balance weight 7 by the adpting flange 4 of end again, thereby realizes balance weight 7 moving forward and backward in crank chute direction.Simultaneously, encoder 1 is converted to the positional information of balance weight 7 on crank 6 signal of telecommunication and is transferred to position control module 11 in real time, position control module 11 feeds back to servo-driven module 10 with testing result, servo-driven module 10 sends regulating command to motor 9 in real time according to balance weight 7 positional informations that obtain, motor 9 is made continuation or is stopped action after receiving regulating command, thereby realizes the accurate location of balance weight 7 on crank 6.
This adjustment process be a position servo control process, encoder 1 produces forward or negative-going pulse signal in real time, pulse signal in-position control module 11 obtains amount of motor rotation and rotation direction, by amount of motor rotation and rotation direction and the amount of movement of balance weight 7 on crank 6 and the corresponding relation of moving direction, obtain real-time amount of movement and the moving direction of balance weight, in position control module, carry out Suitable For Moving-goal Problems amount and the in real time comparison of amount of movement, difference relatively is as the input in each Position Control cycle, circulation through a plurality of position servo control, when the Suitable For Moving-goal Problems amount equates with real-time amount of movement, finish the position servo control process that balance weight 7 is adjusted.Screw-nut body has auto-lock function, can keep the position of balance weight 7 on crank 6 to maintain static, and on the screw-nut body limit switch is housed simultaneously, in order to the control limit displacement, leading screw 3 is shielded.
