Abstract
The utility model relates to a pumping unit, in particular to a non-beam pumping unit, which comprises a base, a drive motor, a support, a reduction gearbox, a crank, a balance block and a polish rod hanger, wherein the 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 a balance block, the crank is mounted with a planet gear, the top of the support is respectively arranged with a polish rod drive wheel and a hinge mount, the hinge mount is provided with a fixing point for a planet wheel drive belt, the plant wheel drive belt bypasses a planet wheel and the polished drive wheel in turn, of which the suspended is connected with the polished rod hanger. The pumping unit can attain longer stroke of a pumping rod via the planet wheel drive belt, thus is beneficial for reducing the dynamic load of the pumping rod, prolonging the service life of the pumping rod and improving the working efficiency of the oil pump. The revolution radius of the planet wheel can be changed by adjusting the position of a crank pin on the crank, thereby adjusting the stroke of the polished rod hanger of the pumping unit.
Description
Technical field:
The utility model relates to a kind of oil pumper, especially a kind of no walking beam type oil pumper.
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 load, its volume and steel consumption are big, and 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 the no beam type oil pumper of long stroke, big burden requirement.
The technical scheme that solves its technical problem employing is:
A kind of no walking beam type oil pumper, comprise: base, drive motors, support, reduction box, crank, balance weight, 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 support top is respectively arranged with polished rod driving wheel and hinge seat, hinge seat is provided with planetary gear rotating band fixed point, described planetary gear rotating band is walked around planetary gear, polished rod driving wheel successively, 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.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, hinge seat 8, planetary gear rotating band 9, end wall bracket 10, crank 11, reduction box 12, belt 13, drive motors 14, base 15, wheel shaft 16, crank-pin 17.
The specific embodiment:
The utility model is described in further detail below in conjunction with drawings and Examples:
A kind of no walking beam 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, hinge seat 8, planetary gear rotating band 9, end wall bracket 10, crank 11, reduction box 12, belt 13, drive motors 14, base 15, wheel shaft 16, crank-pin 17 constitutes, support 4 and reduction box bearing 7 are separately fixed on the base 15, crank 11 is equipped with at reduction box 12 output shaft two ends respectively, and balance weight 5 is equipped with in crank 11 ends, on the described crank 11 planetary gear 6 is housed, described support 4 tops are provided with polished rod driving wheel 1 and hinge seat 8, hinge seat 8 is provided with planetary gear rotating band 9 fixed points, and described planetary gear rotating band 9 is walked around planetary gear 6 successively, polished rod driving wheel 1, its end that dangles is connected with polished rod hanger 3.
The utility model operating principle is summarized as follows:
During blue elephant work, drive motors 14 drives reduction box 12 by belt 13, the output shaft of reduction box 12 drives crank 11 and rotates, and crank 11 drives two planetary gears 6 and revolves round the sun around the axle center of crank 11, and planetary gear 6 therefore pulling moves reciprocatingly around the flexible actuator on its excircle.Because an end of two flexible actuators maintains static, thereby after the other end walks around the fixed wheel commutation, can spur the polished rod hanger 3 that is connected its underpart and do vertically and pump.Polished rod hanger 3 links to each other with sucker rod in the production wellhead, realizes reciprocal reciprocating oil pumping thereby drive oil well pump.
