Description
Technical field
The utility model relates to a kind of oil pumper, specifically a kind of beam pumping unit.
Background technology
Being continuously increased recently as domestic each elephant load, China's majority oil field comes into midlife, and in the even senescence phase, allowable exploitation drastically declines, and in order to alleviate current severe situation, secondary oil recovery, even tertiary oil recovery are progressively implemented in most oil fields；And commonly used approach is exactly water flooding recovery, thus strengthen the dependence for oil pumper；Beam pumping unit refers to, containing walking beam, be commutated by linkage, the oil pumper of crank weight balance, is commonly called as the machine of kowtowing；In walking beam one end of beam pumping unit, horse head is installed, hanging steel rope on horse head；Regulating driving stroke for convenience, steel wire rope uses one and two strands be folded to form, and the doubling end hanging horse head upper end of steel wire rope is hung with the stake of outstanding rope, and two free ends of steel wire rope are sagging to be connected with sucker rod by polished rod eye；In use, the horse head bottom, sucker rod transferred by steel wire rope；Put on horse head, steel wire rope carries sucker rod；During carrying on sucker rod, two strand steel wire ropes can be looped around on the curved outline face of horse head, and and horse head between produce contact stress, contact stress can make between the steel wire of steel wire rope and steel wire produce abrasion；If things go on like this, that section of steel wire rope contacted with horse head easily ruptures；And one fracture any in steel wire rope, in operation oil pumper all can therefore moment lose polished rod load, break balance, swung back by balance weight potential energy effect walking beam, destroy walking beam rack shaft holder, and decelerator is swept away motor and electric cabinet etc. by cutting-off by the waist and walking beam tail balance weight and causes a series of heavy losses.
Utility model content
The purpose of this utility model is to provide a kind of beam pumping unit, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of the utility model offer:
A kind of beam pumping unit, including support, motor fixing frame, wheel bracket, derrick, horse head and solid rope device, described support upper left is provided with motor fixing frame, is bolted and is provided with motor above motor fixing frame, and on the output shaft of motor, drive connection has the first belt pulley；Described support upper center is provided with wheel bracket, and wheel bracket is rotatably connected to wheel disc by wheel disc axle, and wheel disc side is installed with the second belt pulley, and the first belt pulley connects the second belt pulley by belt drives；Described support upper right is provided with derrick, and being connected by link above derrick has walking beam, walking beam side to be provided with lead, and lead is tangent with the track groove on wheel disc, and track groove is oval；Described walking beam right-hand member connects horse head, is installed with the solid rope device that can be each attached on horse head by two strand steel wire ropes on the upside of the arc wheel profile surface of horse head front end；Described solid rope device includes steel wire rope fixation clip and hold-down bolt；It is provided with steel wire rope fixation clip in the upside of the arc wheel profile surface of horse head front end, steel wire rope fixation clip is provided with at least two and connects through hole, the horse head corresponding with connecting through hole is provided with screwed hole, being provided with, within connecting through hole, the hold-down bolt that can be pressed abd fixed on horse head by steel wire rope, the rear end of hold-down bolt is threadably secured respectively and is arranged in screwed hole.
Further, described connection through hole is provided with three.
Further, described steel wire rope fixation clip rear end is provided with that twice are respectively the most corresponding with two strand steel wire ropes respectively and cross section is longitudinal indent of circular arc.
Compared with prior art, the utility model is not in the case of affecting beam pumping unit operation, Gu two strand steel wire ropes in the arc wheel profile surface being looped around horse head front end can be fixed on the upside of the front end of horse head by rope device；Once arbitrarily one fracture, the upper end of another strand steel wire rope still can be suspended on horse head by solid rope device, effectively prevents oil pumper moment from losing and carries, reserve the accident treatment time to field personnel, it is to avoid bigger accident, reduces loss, reduces to lose carrying risk；Simple in construction, applied widely, moving component is few, and energy consumption is low, and the life-span is long, improves oil recovery efficiency, uses track to guide the motion of walking beam, and the operation making oil pumper is more stable, reliable.
