Abstract
The utility model relates to a pumping unit, in particular to an energy-saving pumping unit, which comprises a base, a support, a crank, a balance block, a polished rod hanger and a drive motor, wherein a drive motor, the support and a reduction gearbox support are respectively fixed on the base, two ends of an output shaft of the reduction gearbox are respectively mounted with a crank, the end of the crank is mounted with the balance block, the crank is mounted with a planet wheel, the top of the support is mounted with a hinge mount, a polished rod drive wheel and a variable-diameter wheel, the polished rod drive wheel is fixedly connected with the variable-diameter wheel via a wheel shaft, the hinge mount is provided with a fixing point for a planet wheel drive belt which bypasses the planet wheel to coil the variable-diameter wheel, the polished rod drive belt has a circled joint with the polished rod drive wheel, of which the suspended end is connected with the polished rod hanger. The planet wheel drive belt is beneficial for reducing the dynamic load, prolonging the service life and improving the working efficiency of a pumping rod. The variable-diameter wheel can effectively reduce the maximum torque of the reduction gearbox and a motor, thereby saving energy and prolonging the service life of a speed reducer. The stroke of the polished rod hanger of the pumping unit can be adjusted by adjusting the position of a crank pin.
Description
Technical field:
The utility model relates to a kind of oil pumper, especially a kind of energy-saving beam pumping unit.
Background technology:
Worldwide generally adopt beam pumping unit to carry out underground oil extraction at present.But the shortcoming of beam pumping unit is: for the type of long stroke, big suspending point loading, its volume and steel consumption are big, and its cost performance is relatively poor.
Summary of the invention:
The technical problems to be solved in the utility model: provide that a kind of reliability height, volume are little, the steel consumption is low, save and take up an area of, satisfy long stroke, big burden requirement, economize on electricity considerable energy saving type oil pumper.
Solve the technical scheme that its technical problem adopts:
A kind of energy-saving beam pumping unit, comprise: base, drive motors, support, reduction box, crank, balance weight, the polished rod hanger, drive motors, support and reduction box bearing are separately fixed on the base, crank is equipped with at the reduction gearbox output shaft two ends respectively, crank end is equipped with balance weight, on the described crank planetary gear is housed, described top of the trellis is equipped with hinge seat, polished rod driving wheel and diameter-changing wheel, the polished rod driving wheel is fixedlyed connected by wheel shaft with diameter-changing wheel, hinge seat is provided with planetary gear rotating band fixed point, described planetary gear rotating band is walked around planetary gear and diameter-changing wheel solderless wrapped connection, polished rod rotating band and the solderless wrapped connection of polished rod driving wheel, and its end that dangles is connected with the polished rod hanger.
Compared with prior art, the beneficial effects of the utility model are:
Can obtain than long rod stroke by the planetary gear rotating band, effectively in the operating efficiency that reduces the sucker rod dynamic loading, prolongs sucker rod application life and raising oil well pump.The load inhomogeneities that set diameter-changing wheel can adapt to sucker rod when up and down reciprocatingly transporting shape effectively reduces the peak torque of reduction box and motor, reaches saves energy and prolongs the reducer effect in application life.By regulating the position of crank-pin on crank, can change the revolution radius of planetary gear, thereby realize adjusting oil-extractor polish-rod hanger stroke.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.

Among the figure: polished rod driving wheel 1, polished rod rotating band 2, polished rod hanger 3, support 4, balance weight 5, planetary gear 6, reduction box bearing 7, diameter-changing wheel 8, hinge seat 9, planetary gear rotating band 10, end wall bracket 11, crank 12, reduction box 13, belt 14, drive motors 15, base 16, wheel shaft 17, crank-pin 18.
The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples:
A kind of fuel-saving type oil pumper, by polished rod driving wheel 1, polished rod rotating band 2, polished rod hanger 3, support 4, balance weight 5, planetary gear 6, reduction box bearing 7, diameter-changing wheel 8, hinge seat 9, planetary gear rotating band 10, end wall bracket 11, crank 12, reduction box 13, belt 14, drive motors 15, base 16, wheel shaft 17, crank-pin 18 constitutes, support 4 and reduction box bearing 7 are separately fixed on the base 16, crank 12 is equipped with at reduction box 13 output shaft two ends respectively, balance weight 5 is equipped with in crank 12 ends, planetary gear 6 is housed on the crank 12, hinge seat 9 is equipped with at described support 4 tops, polished rod driving wheel 1 and diameter-changing wheel 8, polished rod driving wheel 1 is fixedlyed connected by wheel shaft 17 with diameter-changing wheel 8, hinge seat 9 is provided with planetary gear rotating band 10 fixed points, described planetary gear drives 10 bands and walks around planetary gear 6 and diameter-changing wheel 8 solderless wrapped connections successively, polished rod rotating band 2 and 1 solderless wrapped connection of polished rod driving wheel, its end that dangles is connected with polished rod hanger 3.
The utility model operating principle is summarized as follows:
During the work of this oil pumper, drive motors 15 drives reduction box 13 by belt 14, the output shaft of reduction box 13 drives crank 12 and rotates, and crank 12 drives two planetary gears 6 and revolves round the sun around the axle center of crank 12, and planetary gear 6 therefore pulling moves reciprocatingly around the planetary gear rotating band 10 on its excircle.Planetary gear rotating band 10 is on diameter-changing wheel 8, and pulling diameter-changing wheel 8 rotates around wheel shaft, also rotates around wheel shaft 17 thereby drive polished rod driving wheel 1.Polished rod driving wheel 1 so pulling are done around the polished rod rotating band 2 on its outer circumference surface and are pumped, polished rod rotating band 2 spurs the polished rod hanger 3 that is connected its underpart again and does vertically and pump, polished rod hanger 3 links to each other with sucker rod in the well head, realizes reciprocal reciprocating oil pumping thereby drive oil well pump.
