Description
The utility model relates to the oil field oil recovery machiner, is a kind of no beam type sucker rod pumping machine, and it can drive the pump barrel and the pump rod relative motion of oil well pump, finishes the oil pumping function.
In the existing oil recovery machiner of China, the sucker rod pumping machine has the chain type oil pumper of beam pumping unit and no walking beam.They all are made up of dynamical system, exchange system, balance sysmte, suspension and frame.Beam pumping unit is realized commutation by rocking arm and walking beam, realizes balance with counterweight; The chain type oil pumper of no walking beam is realized commutation with sprocket wheel and chain, realizes balance with compensating cylinder, gas storage bag, oil pump.Therefore two kinds of oil pumpers all exist from heavy, power consumption height, short, the low shortcoming of efficient of stroke.Chain type oil pumper stroke has raising, has reached six meters strokes, also exists the shortcoming of poor reliability.
The purpose of this utility model provides a kind of long stroke pumping unit, it not only improves length of stroke, reach eight to 16 meters, and can make full use of the deadweight of oil pumper movement parts itself and oil pipe again and heavily realize intrasystem self standing balance, reach and promptly alleviate deadweight, simplified structure, cut down the consumption of energy, have again that cost is low, easy to maintenance, the advantage of good reliability.
The purpose of this utility model is achieved in that oil pumper relies on the chassis to be fixed on the oil well basis on every side, and pit shaft is fixed on the bottom, chassis; On top, chassis frame is installed, platform moving up and down is installed in the middle of frame, platform top is equipped with power drive mechanism and a small amount of counterweight, and the bottom is connecting oil pipe; The power drive mechanism of being made up of motor (motor) and reductor or motor (motor), oil pump, oil cylinder, control valve is installed on the mobile platform, can drive platform and move up and down; The movable and fixed pulley that is fixed on mobile platform, frame, the chassis is formed two cover assembly pulleys, wherein a cover is by being fixed on the movable pulley on the platform and being fixed on that fixed pulley on the frame forms, one end of wire rope is fixed on the platform, the other end is walked around the fixed pulley of central rack and the movable pulley on the platform, and the fixed pulley of walking around upper rack again is fixed on the sucker rod suspender; Wherein another set ofly form by being fixed on movable pulley on the platform and the fixed pulley that is fixed on the chassis, an end of wire rope is fixed on the chassis, and the other end is walked around the movable pulley on the platform, the fixed pulley on the chassis, is fixed on the sucker rod suspender.When power drive mechanism driving platform moved up and down, the spacings between the moving fixed pulley of the moving fixed pulley group of two covers will extend and shorten, and move up and down thereby drive sucker rod.Sucker rod is by connecting the oil well pump pump rod in the middle of the oil pipe; Oil pipe connects the oil well pump pump barrel.When platform moved up and down, the pump rod of oil well pump and pump barrel relatively moved, and finished an oil pumping circulation.Two cover assembly pulleys have solved the effect of increase oil pumper stroke.Solved simultaneously that sucker rod is heavy, oil column is heavy and oil pipe is heavy, platform heavily reaches the static(al) optimum balance between a little counterweight, reached and both reduce the machine dead weight, realized the movement parts of machine self dynamic equilibrium own again by assembly pulley.
The structure of the utility model oil pumper and operating principle will and further specify in conjunction with the accompanying drawings by embodiment.
Fig. 1 is the overall construction drawing of oil pumper, and in Fig. 1, fixed pulley 1,20 is fixed on the frame 21, and fixed pulley 9 is fixed on the chassis 10, and movable pulley 19 and 7 is fixed on the mobile platform 18, and platform relies on guide pillar 17 guiding; Bottom in the middle of the platform is connecting takes over 11, and connects the pump barrel of oil pipe 13 and oil well pump 14 with joint; Chassis 10 is connecting pit shaft 12; Polished rod 3 is connected on the sucker rod suspender, and its polished rod bottom connects the plunger of sucker rod and oil well pump 14; One end of steel cable 2 is fixed on the sucker rod suspender, and the other end is fixed on the mobile platform after walking around pulley 1,19,20; One end of steel wire 4 is fixed on the bottom of sucker rod suspender; The other end is fixed on the chassis 10 after walking around pulley 7,9; Pipeline road is fixed on the frame; Counterweight 15 is placed on the platform, can increase and decrease at any time in well site work operating mode according to oil pumper.
Except that said structure, power drive mechanism of the present utility model has two kinds of designs, its a kind of project organization is: form machine driven system by motor (motor) 8, speed change reversing machine mechanism 26 and ball screw transmission mechanism 6, drive platform 18 and move up and down, finish the oil pumping function; The hydraulic system that its second kind of project organization is made up of motor (motor), hydraulic pump, control valve etc. drives the oil cylinder 22 that is fixed on frame and the platform, and implementation platform moves up and down, and finishes oil pumping function (imaginary positions oil cylinder 22 among the figure).
Operating principle of the present utility model is: no matter the power drive mechanism of oil pumper adopts above-mentioned first kind or second kind of design type, and mobile platform is moved up and down, thereby drives the elongation of movable and fixed pulley spacing or the shortening of two cover assembly pulleys.When the moving fixed pulley spacing of assembly pulley 1-20-19 was extended, assembly pulley 7-9 followed shortening; Steel cable 2 will drive polished rod 3 up strokes, and platform 18 will drive oil pipe 13 downward strokes.When the movable and fixed pulley spacing of assembly pulley 7-9 was extended, assembly pulley 1-20-19 followed shortening, and steel cable 4 will drive the polished rod downward stroke, and platform 18 will drive oil pipe 13 up strokes.The relatively move plunger that can make oil well pump and pump barrel of the moving fixed pulley of assembly pulley relatively moves and finishes the oil pumping function, and this structure has four advantages:
One, can the extend length of stroke of oil pumper.
Two, the multiplying power of assembly pulley can design 3 or 4, basically can realize utilizing beam hanger weight and oil pipe heavily to realize self standing balance, do oil pumper practical application optimum condition dynamic equilibrium adjustment with counterweight again, can guarantee that oil pumper is in the minimum operating mode of power consumption when finishing the oil pumping function.
Three, owing to adopt self standing balance, complete machine weight reduction, conveniently moving.
Four, because the pump barrel motion can prevent that sand is deposited in plunger and the pump barrel gap with oily flow disturbance.
Accompanying drawing 2 is the drive mechanism schematic diagrames that move up and down with the mechanical transmission mechanism implementation platform.In Fig. 2, motor (or motor) 8 drives in-line gears 23, through idle pulley 31 driven wheels 30,32,28,27,33,34,29, realizes slowing down and drives the ball screw transmission and pay 6 work, drives platform and moves up and down.When the some directional runs that move when platform reach terminal point, stroke directions control lever 26 rotates, make idle pulley 31 break away from gear 23,30, idle pulley 24,25 is engaged with gear 23,30, counter-rotation is paid in the ball screw transmission, drive platform and move in the other direction, realization driving platform moves up and down and commutates.Brake 35 is mounted in gear 30 coaxial check mechanism, during left alone without help machine, can guarantee that platform can not fall automatically.
Above-mentioned two kinds of transmission schemes are done one relatively, and the machine driving pattern has that usage range is extensive, the less demanding characteristics of maintenance technique, but structure is complicated; The hydraulic drive pattern has characteristic of simple structure, but usage range is narrower, and maintenance technique is had relatively high expectations.
