Description

Novel walking beam type well oil pumping machine crank pin bush(ing) backing-out punch

Technical field

the utility model relates to the specific purpose tool that crankpin bush changed by a kind of oil field beam pumping unit, specifically a kind of novel walking beam type well oil pumping machine crank pin bush(ing) backing-out punch.

Background technology

at present; the beam pumping unit crank pin lining that oil field uses is fastening and protection part important in crank pins assembly; that trip fine strain of millet formula oil pumper maintains the basic guarantee run well; in field management often there is various potential safety hazard in crank pins; in order to remove a hidden danger; replacing process must be carried out in time; because equipment is in field work for a long time; there is the phenomenons such as corrosion; exist consuming time long when changing crank pins lining; the drawbacks such as worker's labour intensity is large, rate when not only having had a strong impact on oil recovery, also for reducing operating efficiency.

Summary of the invention

the purpose of this utility model is exactly the deficiency existed for prior art, and devises a kind of novel walking beam type well oil pumping machine crank pin bush(ing) backing-out punch.

the utility model is realized by following technical proposals:

novel walking beam type well oil pumping machine crank pin bush(ing) backing-out punch by: location platen, " U " type earhole, jackscrew, lining push pipe, bearing bearing; Its novel walking beam type well oil pumping machine crank pin bush(ing) backing-out punch location platen is boss-shaped T-shape structure, platen center, location is provided with screwed hole, two ends are arranged with " U " type earhole, jackscrew matches with the bearing of lining push pipe bottom through location platen screwed hole; Its lining push pipe is cylindrical-shaped structure, and lining push pipe inside is provided with stepped central through hole, and bearing is equipped with in bottom.

the beneficial effects of the utility model are: structure is simple, easy to use, safe and reliable, effectively raises operating efficiency, reduce worker's labour intensity.
