Abstract
An oil pumping unit with a toothless transmission relates to an oil field machine, which comprises an electric control cabinet, a frame, and an electric machine as well as a brake, a balance weight, and a pumping rod. The frame is provided with a bracket platform, and a guide rope is arranged between the frame seat and the bracket platform; and the balance weight is provided with a guide wheel, while the electric machine output shaft is connected with a driving shaft through a belt in the driving way, wherein the driving shaft is provided with a driving wheel and a counting disc and is connected to the bracket platform; while a relatively small clearance between the bracket platform and the counting disc is emptied out to provide with a switch, and the balance weight is connected with a driving rope, wherein the other end of the driving rope is connected with a suspension rope by winding through the driving wheel; and the suspension rope is connected with an oil rod, and the driving wheel is provided with a winding rope, and the other end of the winding rope is tightly fixed on the balance weight after winding through the driving wheel. The utility model is simple in structure, thus greatly reducing the manufacture cost; and the noise is low, and the oil leakage never happens; the operation is stable and smooth as well as reliable, and the maintenance is convenient, thus quite easy to adjust various technical parameters and save 40 percent to 60 percent of electricity, belonging to an environmental protection device.
Description
Technical field:
The utility model relates to oilfield machinery, especially relates to a kind of oil production equipment.
Background technique:
Number of patent application is its complex structure of oil pumping workover rig of 200410011020.5, the manufacture cost height, and in production and using process, find, the noise level of unit and the accuracy of manufacturing of reduction gears mechanism are closely related, and find the frequent leakage of oil of reducing gear, reduce the operational efficiency of unit, also caused the huge waste of the energy simultaneously.
The model utility content:
Technical problem to be solved in the utility model provides a kind of simple in structure, the gearless transmission oil pumping machine of low cost of manufacture, and this pumping unit greatly reduces operating noise, effected a radical cure oil leakage phenomenon, thereby improved operational efficiency, energy saving has reached environmental protection simultaneously.
The technical solution of the utility model is: comprise electric control cubicle, framework, motor and break thereof, counterweight, sucker rod, be provided with rack platform above the framework, between frame base and the rack platform guide rope is set, counterweight is provided with upper saw pulley, guide rope is clipped between upper saw pulley, it is characterized in that: motor output shaft is provided with small belt pulley, small belt pulley is in transmission connection by belt and big belt pulley, big belt pulley is fixed on the live axle, also be fixed with driving wheel on the live axle, counting scale, live axle is by on the rack platform of bearing fixing on framework, on the rack platform and and counting scale between leave being provided with of less gap near switch, connect on the counterweight and drive rope, the other end that drives rope is walked around driving wheel connection rope hanger, rope hanger connects sucker rod, is fixed with lift rope on the driving wheel, and the other end of lift rope is fastened on the counterweight after walking around driving wheel.
In order to make the pumping unit base of frame parallel, be provided with 4 adjustable jackscrews in base of frame with horizontal plane.
Step down to well repairing machine during for well workover and pumping unit is removed, be provided with 4 rollers in base of frame.
The utility model does not have gear drive, and is simple in structure, thereby reduces manufacture cost greatly, and noise is very low simultaneously, do not have oil leakage phenomenon, running steadily, is reliably maintained simple, convenient, and regulate various technical parameters and be very easy to, economize on electricity 40%-60% belongs to environment protection type equipment.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment:
With reference to Fig. 1,2, the utility model comprises electric control cubicle 1, framework 7, motor 8 and break 10 thereof, counterweight 4, sucker rod 13, be provided with rack platform 17 above the framework, guide rope 6 is set between frame base and the rack platform, counterweight is provided with upper saw pulley 5, guide rope is clipped between upper saw pulley, motor output shaft is provided with small belt pulley 9, small belt pulley is in transmission connection by belt 11 and big belt pulley 12, big belt pulley is fixed on the live axle 18, also be fixed with driving wheel 19 on the live axle, counting scale 22, live axle is fixed on the rack platform above the framework by bearing 21, on the rack platform and and counting scale between leave being provided with of less gap near switch 20, connect on the counterweight and drive rope 16, the other end that drives rope is walked around driving wheel and is connected rope hanger 14, rope hanger connects sucker rod 13, be fixed with lift rope 15 on the driving wheel, the other end of lift rope is fastened on the counterweight after walking around driving wheel, and base of frame is provided with 4 adjustable jackscrews 3 and 4 rollers 2.
During oil pumping machine oil pumping, motor in electric control cubicle with near the control of switch under positive and negative regularly rotation, at this moment, small belt pulley fixing on the motor output shaft drives the positive and negative rotation of big belt pulley by belt, thereby the also positive and negative rotation of live axle and driving wheel, counterweight by driving rope band on the driving wheel and sucker rod pumps, and therefore, sucker rod drives oil well pump and extracts fluid.And counterweight pumps along guide rope under the cooperation of guide rope and upper saw pulley.Thereby lift rope has the effect that counterweight makes rope hanger be connected with sucker rod that promotes when pumping unit is installed, and when sucker rod disconnects, counterweight makes driving wheel rotate under the effect of lift rope, motor produces the overload phenomenon, at this moment under the effect of electric control cubicle, brake, thus counterweight can not freely be fallen, avoid producing the bump accident.When pumping unit was not pumped, lift rope was taken off from counterweight, can do the space telpher and use.
Small belt pulley in the utility model, big belt pulley, belt can use minor sprocket, hinge wheel, chain to replace respectively, so that drive bigger load.
