Abstract
Disclosed is a crank pin bush puller for a beam pumping unit, which comprises driving nuts, a central rod, a retainer ring, a jacket, a bearing, a support frame, ribbed slabs, a retaining nut, a spare cap, a cover board and a tension nut. The support frame is a channel steel structure; the cross section of the support frame is rectangular; a through hole is arranged at the center of the support frame; and each of the upper inner side and the lower inner side of the support frame is provided with a right-angled triangular ribbed slab. Crown driving nuts are fixed from right to left on the T-shaped central rod which is provided with male threads; and the retainer ring, the jacket, the bearing and the support frame are fixed behind the driving nuts at distance. The support frame is limited at the middle of the central rod by the retaining nut and the spare cap. The round cover board and the tension nut are installed at the left end of the central rod. The cover board can rotate on the central rod and the diameter of the cover board is between the inner diameter and the outer diameter of the bush. The crank pin bush puller is simple in structure, easy to make and convenient to operate, and is safe and reliable. When used to adjust the crank pin of the beam pumping unit, the crank pin bush puller is time-saving and energy-saving to pull the bush from a crank hole or to install the bush. The crank pin bush puller reduces oil well pause time, improves oil well production efficiency and increases crude oil yield.
Description
One, technical field
The utility model relates to a kind of oil field mechanical oil recovery aid, particularly a kind of beam type oil pumping machine crank pin bush(ing) replacer.
Two, background technology
In oil-field oil pumper recovers the oil production, the crank of oil pumper and connecting rod, walking beam connect to form quadric chain by crank-pin, Crank Pin on Pumping Units is the crucial attaching parts in the quadric chain, the easiest breaking down, crankpin bush is again an accessory of Crank Pin on Pumping Units, its effect is: utilize the tapering of lining and crank-pin to realize interference fit on the one hand, crank-pin is fixed on the crank; Protect crank hole and crank-pin on the other hand, reduce the wearing and tearing of crank hole and crank-pin.Therefore, lining is to guarantee the fastening critical component of crank-pin, when changing crankpin bush, lining and crank hole face are very tight, and frictional force is big, and lining is in the same place with the crank hole rust easily, the scene mainly is to knock lining with sledgehammer, deviate from up to lining, waste time and energy, and cause crank hole to damage easily, it is long to stop the well time, not only reduce crude output, and for the serious well that shakes out, very easily caused the sand card problems such as well of lying.
Three, utility model content
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of beam type oil pumping machine crank pin bush(ing) replacer is provided, the problem that lining is difficult to take out when adjusting to solve Crank Pin on Pumping Units.
Its technical scheme is: comprise power nut, center-pole, ring washer, sheath, bearing, bracing frame, floor, stop nut, be equipped with cap, cover plate, tightening nut; Its bracing frame is the channel-section steel structure, and its cross section is a rectangle, and the center is provided with a through hole, and inner edge respectively is provided with a right angled triangle floor up and down, to increase the intensity of bracing frame; Be provided with externally threaded "T"-shaped center-pole from right to left right-hand member be fixed with crown power nut, be fixed with ring washer, sheath, bearing, bracing frame behind the certain intervals, by stopping nut, being equipped with on the cap centre at center-pole, bracing frame is spacing, the left end of center-pole is equipped with circular cover, tightening nut, cover plate can rotate on center-pole, and the diameter of cover plate is between the inside and outside footpath of lining.
According to the beam type oil pumping machine crank pin bush(ing) replacer that such scheme is made, simple in structure, make easily, easy to operate, safe and reliable, can be applicable to various model beam-pumping units, according to the inside and outside footpath of lining, only changing cover plate gets final product, when Crank Pin on Pumping Units was adjusted, it is time saving and energy saving that lining is taken out from crank hole or installs, and reduces and stop the well time, rate when improving oil well production increases crude output.
Four, description of drawings
The utility model The field schematic diagram.
In the accompanying drawing, 1-power nut, 2-center-pole, 3-ring washer, 4-sheath, 5-bearing, 6-bracing frame, 7-floor, 8-stop nut, 9-be equipped with caps, 10-oil pumping machine crank, 11-lining, 12-cover plate, 13-tightening nut.
Five, the specific embodiment
In conjunction with the accompanying drawings the utility model is further described:
The utility model comprises: power nut 1, center-pole 2, ring washer 3, sheath 4, bearing 5, bracing frame 6, floor 7, stop nut 8, be equipped with cap 9, cover plate 12, tightening nut 13; Its bracing frame 6 is the channel-section steel structure, and its cross section is a rectangle, and the center is provided with a through hole, and inner edge respectively is provided with a right angled triangle floor 7 up and down; Be provided with externally threaded "T"-shaped center-pole 2 from right to left right-hand member be fixed with crown power nut 1, be fixed with ring washer 3, sheath 4, bearing 5, bracing frame 6 behind the certain intervals, by stopping nut 8, being equipped with on the cap 9 centre at center-pole 2, bracing frame 6 is spacing, the left end of center-pole 2 is equipped with circular cover 12, tightening nut 13, cover plate 12 can rotate on center-pole 2, and the diameter of cover plate 12 is between the inside and outside footpath of lining 11.Center-pole 2 is penetrated from the right, crankpin bush 11 holes, cover plate 12 is put from center-pole 2 left ends, tighten tightening nut 13 and urgent with wrench, with the tight power nut 1 of another wrench, can from oil pumping machine crank 10 holes, take off lining 11, otherwise, can load onto lining 11.
