Because the coil springs can replace balancing weights during energy storage to regulate the load balance of the upward stroke and the downward stroke of the oil pumping unit, the oil pumping unit is more stable in the whole running process, the motor is more stable in running, the energy consumption of the motor is reduced, the electrical energy is saved, and a derrick is saved. Compared with the prior art, the derrick-free mechanical energy-storage oil pumping unit has the advantages that the structure is simple, the use is convenient, the cost is low, and the efficiency is high.

Description

Without derrick mechanical accumulated energy oil pumper
Technical field
The present invention relates to the petroleum production engineering mechanical field, specifically a kind of without derrick mechanical accumulated energy oil pumper in the oil pumper.
Background technology
The reciprocating beam-pumping unit of at present oil extraction in oil field use has two classes, and a class is the formula of kowtowing or claims beam pumping unit, mainly is comprised of derrick, walking beam, balancing weight, pull rope, reduction box, motor, electric machine controller and braking mechanism etc.; Another kind of is vertical oil-pumping machine, and vertical oil-pumping machine mainly is comprised of vertical derrick, wide belt, belt pulley, balancing weight, reduction box, changement, motor, electric machine controller and braking mechanism etc. especially take belt type pumping unit as main.Reciprocating beam-pumping unit carries in up (carrying oil) process greatly, releasing bearing when descending, and this just need to be equipped with weight block to oil pumper and solve the unbalanced problem of load.Because the balancing weight own wt can not be adjusted, and the load of oil pumper up-down stroke is continuous variation, this just causes, and motor load is unstable, loss serious and do not utilize energy-conservation.Other two kinds of oil pumpers all need to be provided with special derrick and larger base, and its complex structure and floor space are large.
Summary of the invention
Purpose of the present invention is exactly the defective that exists for prior art, provide a kind of simple in structure, stable, energy conservation without derrick mechanical accumulated energy oil pumper.
Its technical scheme is: comprise motor 3, electric machine controller 1, be fixedly connected with bracing frame 9 at the two ends of horizontal fixed axis 8, be provided with bearing 13 at the horizontal fixed axis 8 near bracing frame 9 inboards, bearing 13 outsides connect respectively driving wheel 7 and braked wheel 14, driving wheel 7 and braked wheel 14 inboards are fixedly connected with roller 5, be provided with rigidity wind spring 15 in the roller 5, rigidity wind spring 15 the inners are connected with horizontal fixed axis 8, rigidity wind spring 15 outer ends and roller 5 inwalls are connected, pull rope 12 is connected to the outer wall of roller 5, and motor output wheel 2 is connected with driving wheel 7; Described motor 3 is the bidirectional speed governing motor.
Such scheme also comprises: equipped braking mechanism on the braked wheel 14.Horizontal fixed axis 8 is fixedly connected with by pin key 16 with bracing frame 9; Adopt bolt 17 to be connected and fixed between driving wheel 7, braked wheel 14 and the roller 5.
The present invention has been owing to adopted the wind spring accumulation of energy to replace balancing weight to adjust the counterweight balance of oil pumper up-down stroke, makes oil pumper whole service process with more stable, and the motor operation is more steady, has both reduced the loss of motor, has saved electric energy, has saved again derrick; Wind spring holds and more is conducive to adjust the oil pumper up-down stroke simultaneously; Cooperate the bidirectional speed governing motor, reduction box and changement in the middle of having saved.Compared with prior art, has advantage simple in structure, easy to use, with low cost, that efficient is high.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the present invention;
Fig. 2 be among Fig. 1 A-A to the structural representation of sectional view.
The specific embodiment
Such as Fig. 1, shown in 2, a kind of without derrick mechanical accumulated energy oil pumper, two ends at horizontal fixed axis 8 are fixedly connected with bracing frame 9 by pin key 16, be provided with bearing 13 at the horizontal fixed axis 8 near bracing frame 9 inboards, bearing 13 outsides connect respectively driving wheel 7 and braked wheel 14, driving wheel 7 and braked wheel 14 inboards are fixedly connected with roller 5, be provided with rigidity wind spring 15 in the roller 5, rigidity wind spring 15 the inners are connected with horizontal fixed axis 8, rigidity wind spring 15 outer ends and roller 5 inwalls are connected, pull rope 12 is connected to the outer wall of roller 5, and the outer end of pull rope 12 connects polished rod eye 11, and the drive 2 of motor 3 and the driving wheel of roller 7 are connected by belt.Motor 3 adopts the bidirectional speed governing motor, by electric machine controller 1 control.
Also comprise in above-described embodiment: equipped braking mechanism on the braked wheel 14.Adopt bolt 17 to be connected and fixed between driving wheel 7, braked wheel 14 and the roller 5.Adopt bolt 17 fixing between driving wheel and the roller, can adjust the rigidity wind spring winding number of turns in the roller, reach the effect of adjusting balance torsional with this.Set up pull rope back-up ring 6 in roller 5 neighborings, play restriction pull rope trend.
Operating principle of the present invention is: when clockwise rotating (being down stroke) at the driven by motor driving wheel, roller rotates synchronously around solid center dead axle, and the rigidity volume transverse slat of roller inside tightens thereupon gradually, and energy stores by rigidity volume transverse slat.When down stroke reached lower dead center, motor is backward rotation under the control of electric machine controller, and oil pumper begins upstroke.When upstroke begins, when down-hole load also is maximum, this moment, rigidity volume transverse slat also was the position of accumulation of energy maximum, motor and the cooperation of rigidity volume transverse slat lift down-hole load jointly, raising along with upstroke, down-hole load progressively reduces, and rigidity volume transverse slat also is that accumulation of energy is also gradually reducing, and motor remains on relatively stable load condition substantially like this.When upstroke reached top dead centre, the accumulation of energy of rigidity volume transverse slat discharged complete substantially, got back to the starting point of down stroke, and motor begins again to be stored in gradually rigidity volume transverse slat together with the energy of down-hole load.
