Detailed description of the invention
This back layer stacked pull bar long stroke pumping unit comprises motor 1, support baseboard 2, gear reduction unit 3, walking beam 13, crank 4 and pylon 6.The upper surface side of support baseboard 2 is fixed with motor 1, and the upper surface opposite side of support baseboard 2 is fixed with pylon 6; Pylon 6 top is movably installed with walking beam 13 by bearing pin; The termination, front end of walking beam 13 is provided with horse head 11; The forward position circular arc portion of horse head 11 is provided with roller 10 by bearing.
The rear end of walking beam 13 is provided with beam balance balancing weight 19; The walking beam 13 of beam balance balancing weight 19 side is movably installed with go the big figure pull bar 17 and Vee formation of front triangle by bearing to go the big figure pull bar 18.Go the big figure pull bar 17 and Vee formation of front triangle goes the big figure between pull bar 18 and pylon 6 and is provided with front push rod 14 and rear push rod 15.One end of front push rod 14 and rear push rod 15 is flexibly connected with pylon 6 respectively by bearing, and the other end of front push rod 14 is flexibly connected by bearing and the front triangle pull bar 17 that goes the big figure; The other end of rear push rod 15 is flexibly connected by bearing and the Vee formation pull bar 18 that goes the big figure.Horse head 11 top is provided with front fixed pulley 12, and the go the big figure top of pull bar 17 of front triangle is provided with rear fixed pulley 16.
Support baseboard 2 between motor 1 and pylon 6 is provided with gear reduction unit 3, and motor 1 is connected with gear reduction unit 3 by driving-belt 21.The output shaft of gear reduction unit 3 is provided with crank 4, the tail end termination of walking beam 13 is provided with movable part 20, and crank 4 is connected with movable part 20 by connecting rod 5.
Vee formation pull bar 18 top that goes the big figure is fixed with wire rope 9, and one end of wire rope 9 is connected with sucker rod 7 by rope locking device 8 with horse head 11 around rear fixed pulley 16, front fixed pulley 12.
During the work of this back layer stacked pull bar long stroke pumping unit, after motor 1 is slowed down by driving-belt 21 and gear reduction unit 3, the output shaft of gear reduction unit 3 is made to obtain the rotating speed of amount, output shaft due to gear reduction unit 3 is provided with crank 4, and be connected by the movable part 20 of connecting rod with walking beam 13 rear end, simultaneously also because the middle part of walking beam 13 is movably connected by the top of bearing and pylon 6, thus crank 4, connecting rod 5, walking beam 13 and pylon 6 is made to form a four-bar mechanism.And then make front triangle go the big figure pull bar 18, walking beam 13, front push rod 14 and rear push rod 15, the pylon 6 of pull bar 17 and Vee formation that go the big figure form another independently four-bar mechanism.In the course of work, in the four-bar mechanism that crank 4, connecting rod 5, walking beam 13 and pylon 6 are formed, the walking beam 13 that rotarily drives of crank 4 pumps, thus horse head 11 is also pumped thereupon, and wire rope 9 also moves up and down along the forward position of horse head 11.
Another going the big figure that pull bar 17 and Vee formation go the big figure that pull bar 18, walking beam 13, front push rod 14 and rear push rod 15, pylon 6 form at front triangle is independently in four-bar mechanism.
Walking beam 13 pumps and drives front triangle pull bar 17, the Vee formation pull bar 18 that goes the big figure that goes the big figure to move, go the big figure pull bar 18 and horse head 11 of Vee formation synchronously pulls wire rope 9 to move, thus achieve the move distance that first time increases wire rope 9, increase oil pumper stroke thus, go the big figure pull bar 17 and Vee formation of front triangle goes the big figure the synchronous jack-up wire rope 9 of pull bar 18, thus second time increases the move distance of wire rope 9, again increase oil pumper stroke thus.
The go the big figure roller 10 of installation of front fixed pulley 12 that rear fixed pulley 16 and horse head 11 that pull bar 17 is installed are installed and horse head 11 forward position circular arc portion of the front triangle of this back layer stacked pull bar long stroke pumping unit can reduce the friction of wire rope 9; The beam balance balancing weight 19 that walking beam 13 rear end is installed can balance the moment that in down-hole load and oil pumping process, walking beam 13 deadweight produces, thus makes oil pumper even running; And then make Pumping Unit more stable.
This back layer stacked pull bar long stroke pumping unit overcomes the drawback of traditional four bar oil pumpers, reach the effect of balance horse head 11 fractional load, alleviate crank 4 moment of torsion, reduce power consumption, increase effectively stroke and reduce jig frequency, improve actual length of stroke and the coefficient of fullness of oil well pump.Make motor 1 while consuming identical electric energy, effectively can increase the oil pumping amount of oil pumper, improve the operating efficiency of oil pumper, reach the effect of energy-saving and emission-reduction.
