Description
One, technical field
The utility model belongs to the oil exploration equipment field, especially relates to a kind of swinging block six-bar mechanism oil extractor.
Two, background technology
At home and abroad in the petroleum production engineering of oil field, mechanical oil recovery equip ment commonly used is a beam pumping unit at present.Beam pumping unit because simple in structure, use reliable, convenient operating maintenance, characteristics such as safe operation reliably and with long-term in abominable natural environment, make it obtain using widely in oil extraction process, what still adopted more than 90% in China oil field at present is beam pumping unit.But because its torque factor is bigger than normal, cause the net torque peak value on the crank axle excessive, it is excessive to fluctuate, and it is big that energy consumption also becomes thereupon; The problem that mainly has following three aspects: 1, oil pumper energy consumption height; 2, the motor installed power is big, i.e. " low load with strong power " phenomenon; 3, the fluctuation of polished rod load is big.Particularly, just cause the installed power capacity of motor to increase, promptly caused " low load with strong power " phenomenon because the fluctuation (CLF) of load is excessive.For the energy consumption that reduces beam pumping unit, the installed power and the load fluctuation of motor, a lot of Technical Transformation Study that beam pumping unit has been carried out in recent years, two horse head oil pumpers, down eccentric barbell formula oil pumper, curved beam pumping unit or the like have been developed, obtained certain energy-saving effect, especially the most obvious with two horse head oil pump energy-saving effects, the installed power of motor is minimized, but because this oil pumper adopted flexible link, make oil pumper at work the reliability of flexible link reduce greatly; And because the oil pumper of these types all is the improvement of doing on the basis of common beam oil pumper, so they do not change technical some the intrinsic defectives of original oil pumper fully.
Three, summary of the invention
Technical problem to be solved in the utility model is the deficiency at above-mentioned existence of the prior art, and a kind of swinging block six-bar mechanism oil extractor is provided, and its compact conformation is safe and reliable during work, and balance is good, and energy-saving effect is remarkable, and installed power is low.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of swinging block six-bar mechanism oil extractor, comprise motor, the belt gear that is connected and is driven by it with described motor, be connected the reducer on the output shaft of described belt gear, be connected on the output shaft of described reducer and drive the crank that rotates by this reducer, be connected connecting rod and frame on the crank, be hinged with fork and rocking bar on the described frame, the front end of described rocking bar is provided with horse head, be connected the Rope rod connector on the described horse head and be installed in sucker rod on the described Rope rod connector by steel cable, it is characterized in that: one in described fork and the rocking bar is equipped with guide rail, in fork and the rocking bar another is equipped with the slide block that slides on this guide rail, and the slip of slide block on guide rail when swinging by fork, drive rocking bar and be fulcrum and do and swing up and down motion, drive sucker rod then and do and pump with the frame.
Described guide rail is rail plate or rolling guide.
The front end of described fork is used for installing described guide rail or slide block, and the rear end of fork is hinged on the frame or the rear end of fork is connected with connecting rod, is hinged with connecting rod between the fork front-end and back-end or is hinged on the frame.
On the described rocking bar, and between the tie point of rocking bar front end and rocking bar and frame, be used for installing described guide rail or slide block, stretch out outside frame the rear end of rocking bar, and the rear end of rocking bar is provided with the rocking bar balance weight.
The upper end of described connecting rod is connected between the tie point of the front end of fork and frame or is connected the rear end of fork, and the lower end of connecting rod is connected with crank.
The utility model compared with prior art has following advantage: 1, the mechanical transmission structure technology maturation that adopts in compact conformation, safe and reliable, the utility model, realize easily.2, owing to do not adopt any flexible piece in the utility model, the oil pumper reliability during operation is greatly improved.3, the experiment proved that, the utility model is inhaled under the operating mode at any pump, crank net torque curve all is very level and smooth, level off to straight line (Fig. 7), the fluctuation of load is very little, the CLF value only is about 1.005, conventional beam-pumping unit CLF is about 1.66 (Fig. 8), two horse head oil pumper CLF are about 1.1 (Fig. 9), the utility model is in all oil pumpers, the CLF value is minimum, does not have tangible peak value and valley, and load fluctuation is littler, the energy-saving effect of oil pumper is just good more, so the energy-saving effect highly significant, than two horse head oil pump energy-savings about 25%, and the installed power capacity of motor is very little, output power of motor is compared with conventional beam-pumping unit and has been descended 65%, with two horse head oil pumpers, down eccentric barbell formula oil pumper, energy-saving beam pumping units such as curved beam pumping unit are compared, and descend 36%, greatly reduce the cost of purchasing motor.The utility model has solved the problem of three aspects that exist in the present oil pumper technology described in the background technology fully.
