Description

A kind of caput Equi Asini bracing means used for oil extractor

Technical field

This utility model relates to a kind of oil production equipment, particularly to a kind of caput Equi Asini bracing means used for oil extractor。

Background technology

Caput Equi Asini is the significant components during oil pumper produces, and when its effect is to ensure that oil pumping, polished rod is directed at the center of well head all the time。Caput Equi Asini owing to subject bigger load in up-down stroke process, along with the junction of the prolongation of the time of operation, caput Equi Asini and walking beam inevitably produces gap, is all adopt horse head pin to fasten, but has micro gap and exist in routine work。Present production oil pumper is all eight types, ten types, and oil pumper model is more big, and underground sucker rod post and fluid column weight that caput Equi Asini bears are more big, causes that pumping unit horsehead occurs the probability shaken more big because there being gap。In the winter that particularly north is cold, because day and night temperature is relatively big, make pumping unit can produce bursting by freezing, or the phenomenon such as expand with heat and contract with cold, more can aggravate the generation of pumping unit accident。Therefore, pumping unit horsehead gap has been administered most important。

Chinese patent literature publication number is 204663501U, patent name is " the fixing device of a kind of pumping unit horsehead ", described caput Equi Asini is fixed the upper end that key seat is arranged in the middle part of caput Equi Asini medial surface in installing hole, the lower end that key seat is arranged in the middle part of caput Equi Asini medial surface in installing hole is fixed under caput Equi Asini, walking beam is fixed key seat and is arranged on the upper surface of walking beam one end, fix key seat under walking beam and be arranged on the lower surface of walking beam one end, upper steady pin from top to bottom sequentially passes through fixes key seat on caput Equi Asini, walking beam is fixed key seat, lower steady pin from top to bottom sequentially passes through and fixes key seat under walking beam, key seat is fixed under caput Equi Asini, base is fixedly mounted on the upper surface of walking beam, two fastening screws are mounted side by side on base by two fixing nuts, and each one end of fastening screw contacts with the medial surface of caput Equi Asini。But it is one-side fixing to there is the problem that oil pumper has simply been used, it is impossible to ensure that oil pumper does not result in caput Equi Asini abrasion or loosens after using for a long time。

Summary of the invention

The purpose of this utility model is aiming at the drawbacks described above that prior art exists, it is provided that a kind of caput Equi Asini bracing means used for oil extractor。Solve oil pumper use for a long time cause abrasion or loosen, the problem that fastness is poor。

Its technical scheme is: include caput Equi Asini, caput Equi Asini gim peg, walking beam gim peg, caput Equi Asini steady pin, jacking mechanism, bracing means, walking beam, the upper and lower both sides, front end of walking beam are respectively through the caput Equi Asini that is connected of caput Equi Asini steady pin with caput Equi Asini gim peg and walking beam gim peg, the middle upper end of caput Equi Asini is provided with jacking mechanism, jacking mechanism is fixed on the upper surface of walking beam, jacking mechanism be provided above with bracing means, one end of bracing means connects the upper end of caput Equi Asini, the other end connects the rear end of walking beam, described bracing means includes fastener, transverse slat, bearing, screw rod, connecting rod, sleeve pipe, fixing tailstock, steady pin, the inside of fastener and transverse slat is tightened together by latching, the upper end of transverse slat is provided with bearing, the rear end of transverse slat is provided with connecting rod, connecting rod is set with sleeve pipe, connecting rod and fixing tailstock are linked together by steady pin。

Having two screws on above-mentioned bearing, screw rod is each passed through two screws of bearing, and the head end of screw rod withstands on the rear wall of fastener, and the screw rod of bearing front and back end connects retaining nut respectively。

The beneficial effects of the utility model are: effectively avoid the expansion in gap between caput Equi Asini and walking beam, prevent caput Equi Asini vibrations or slight rocking and drawing crack caput Equi Asini, it is more firm that installation bracing means makes caput Equi Asini be connected with walking beam, both prevented and loosened and pin seat Fast Wearing because oil pumper runs the horse head pin caused under varying load effect, also eliminated because loosening the accident potential impacting the caput Equi Asini cracking caused。
