Background technology
At the existing mechanical oil production model of China, or there to be bar to recover the oil as main, account for more than 80% of all machine-pumped oil wells.The widely used oil pumping machinery in China oil field is mainly beam pumping unit.It has simple in structure, reliable, long-lived advantage.But due to its operating principle and structural problem, exist that efficient is low, up-down stroke acting imbalance causes that machine operation is unstable, to impact the phenomenons such as short, the large heaviness of volume of large life-span serious, development long stroke, low jig frequency, the variable frequency control development is very difficult.The chain type reversing pumping unit of development had played certain effect in long stroke, low jig frequency oil pumping in recent years.But because of sprocket wheel, the chain drive of using, exist quick abrasion, application life short, exist in chain and sprocket engagement and impact, the shortcomings such as lubricated difficulty, maintenance inconvenience.Also the motor positive and inverse oil pumper of development transfers ginseng easily in recent years, but the shortcomings such as moment of torsion is inadequate that commutate.Especially two oil wells are a lot of apart from very near situation, must two oil pumpers of frame, extremely waste.
Summary of the invention
The utility model overcomes the deficiencies in the prior art part, and a kind of novel double tower belt type pumping unit is provided, and this oil pumper rationally utilizes the symmetrical balance sucker rod of double tower self gravitation, energy requirement is little, energy consumption is low, and stable working is convenient to automation and telemanagement.
In order to solve the problems of the technologies described above, double tower belt-type self-balancing pumping unit of the present utility model is by base, A tower frame, B tower frame, A cylinder, B cylinder, A crown sheave, B crown sheave, A rolling stand, B rolling stand, belt, polished rod eye, motor, cylinder, speed reducer for idle-work reversing intelligent oil pumping machine, positioning track.A tower frame and B tower frame are fixed on base two ends, the positioning track is fixed on base, A tower frame and B tower frame transverse shifting are connected in the positioning track, A rolling stand and B rolling stand are connected in respectively the lower end of A tower frame and B tower frame by turning cylinder, A crown sheave and B crown sheave are connected in A tower frame and B tower frame tower top top by turning cylinder respectively, A cylinder and B cylinder are connected on A rolling stand and B rolling stand by turning cylinder respectively, cylinder is to be connected with speed reducer for idle-work reversing intelligent oil pumping machine by belt, motor is connected with speed reducer for idle-work reversing intelligent oil pumping machine, the two ends of belt are polished rod eye and polished rod eye fixedly, belt is by mode and the A crown sheave of socket, the A cylinder, cylinder, the B cylinder is connected with the B crown sheave.
On described polished rod eye, sensor is arranged, gather sucker rod displacement and up-downgoing speed data, be transferred to control terminal, regulate stroke and jig frequency, and Payload Monitoring And Control.
Sliding bearing that described crown sheave, cylinder are connected with frame adopts the magnetic suspension lubricating system, and has sensor Real-time Collection axle that andfrictional conditions between bearing shell is arranged.
Described motor is by its startup of electric control system controls, stop, rotating.
Described positioning track is used for regulating the distance of A tower frame and B tower frame, can be used in the oil producing operation of two mouthfuls of oil wells in the certain distance scope.

In figure: 1 is the A crown sheave, and 2 is belt, and 3 is polished rod eye, 4 is A tower frame, and 5 is motor, and 6 is base, 7 is the A cylinder, and 8 is the A rolling stand, and 9 is cylinder, 10 is speed reducer for idle-work reversing intelligent oil pumping machine, and 11 are the positioning track, and 12 is the B rolling stand, 13 is the B cylinder, and 14 is polished rod eye, and 15 is belt, 16 is B tower frame, and 17 is the B crown sheave.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model double tower belt-type self-balancing pumping unit is described in further detail.
As shown in the figure, double tower belt-type self-balancing pumping unit of the present utility model comprises base 6, A tower frame 4, B tower frame 16, A cylinder 7, B cylinder 13, A crown sheave 1, B crown sheave 17, A rolling stand 8, B rolling stand 12, belt 2, polished rod eye 3, motor 5, cylinder 9, speed reducer for idle-work reversing intelligent oil pumping machine 10, positioning track 11.A tower frame 4, B tower frame 16 are assemblied on base 6; Positioning track 11 is fixed on base 6, and A tower frame 4, B tower frame 16 can be crossed along the distance between positioning track 11 slidable adjustment two towers; A rolling stand 8, B rolling stand 12 are separately fixed at the lower end of A tower frame 4, B tower frame 16; A crown sheave 1, B crown sheave 17 are separately positioned on A tower frame 4, B tower frame 16 tower tops; A cylinder 7, B cylinder 13 are assemblied in respectively on A rolling stand 8, B rolling stand 12; Cylinder 9 is to be connected with speed reducer for idle-work reversing intelligent oil pumping machine 10 by belt; Motor 3 is connected with speed reducer for idle-work reversing intelligent oil pumping machine 10; The two ends of belt 2 are polished rod eye 3 and polished rod eye 14 fixedly, strides across A crown sheave 1, A cylinder 7, cylinder 9, B cylinder 13, B crown sheave 17.
During work, motor 5 clockwise rotates, and clockwise rotates through driving cylinder 9 after speed reducer for idle-work reversing intelligent oil pumping machine 10 speed changes, does upstroke by the transmission drive A tower sucker rod of belt 2, and B tower sucker rod is done down stroke; After moving to given stroke, 5 counter-rotatings of electric control system controls motor, thus A tower sucker rod is done down stroke, and B tower sucker rod is done upstroke.In oil pumping process because two sucker rods are connected by belt tension, therefore can balance himself gravity, motor only need provide the merit of lifting oil and the merit of drawing sucker rod need not be provided, and has greatly saved energy.Be arranged on displacement, operating rate and load condition that sensor on polished rod eye can collect sucker rod, and the information that collects is fed back to control system, conduction time and the switching frequency of control system regulating electric machine, thus the purpose of stroke and jig frequency is regulated in realization.
