Abstract
The utility model relates to a back horse head anti-fatigue device for special-shaped walking beam type oil pumping machines for oil production in oil fields. A back horse head of the utility model is also additionally provided with a suspension shaft, a guide stopper, an anti-disconnection stopper, and a safety protective pin in an original box type structure, the tail end of a walking beam is additionally provided with a spacing stopper and is installed in the back horse head, and the back horse head is connected with the walking beam in a suspending mode. The utility model has the advantages that the structure is reasonable, the self-lock is realized, fatigue sources are eliminated, the damage caused by the fatigue is avoided, and the use reliability of oil pumping machines is raised.
Description
The utility model relates to a kind of oil field and recovers the oil with horse head antifatigue device behind the special beam pumping units.
At present, recover the oil and mainly rely on oil pumper that oil is given rise to surface gathering system in domestic each oil field, and special beam pumping units (two horse head oil pumper) is a kind of energy-conservation oil pumper preferably, use comparatively extensive, but The field through several years, in back horse head and walking beam bearing pin point of attachment generation fatigue damage phenomenon, make the oil pumper machine life be subjected to very big influence.
The purpose of this utility model is exactly a horse head antifatigue device behind a kind of special beam pumping units that provides at the deficiency of original design, it has changed the connecting mode of walking beam, back horse head, solved the fatigue damage phenomenon, can guarantee effectively that oil pumper normally moves.
The purpose of this utility model is achieved in that the back horse head has increased suspended axle, guiding block, anticreep block and security protection pin again in former case structure.Increased positive stop at the walking beam afterbody.The walking beam afterbody is fit in the horse head of back, and back horse head adopts to hang with walking beam and connects.
The utility model is simple and reasonable, installation, easy to use, low cost of manufacture, change the connecting mode of back horse head and walking beam, realized self-locking, eliminated tired source, avoid fatigue damage, improved the reliability that oil pumper uses, be convenient to further promoting the use of of this energy-conservation type.
Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of horse head parts behind the utility model.
Fig. 3 is the structural representation of the utility model walking beam parts.
Referring to Fig. 1,2,3, the utility model is a horse head antifatigue device behind a kind of special beam pumping units, and it is to be made of the positive stop 7 on the suspended axle 3, anticreep block 5, guiding block 6 and the walking beam 2 that are fixed on the horse head 1 of back.The middle part of back horse head 1 is passed through back horse head 1 to connect suspended axle 3 by guiding block 6 among Fig. 2, is installed to gear block 7 places in the walking beam 2, realizes the connection (see figure 1) of walking beam 2 and back horse head 1.Anticreep block 5 plays the effect that prevents that walking beam from skidding off among Fig. 2; Positive stop 7 can prevent walking beam 2 play in the horse head 1 of back, can bear the effect of transmitting component again; The effect of the security protection pin 4 among Fig. 2 is after walking beam 2 and back horse head 1 connect, and when lifting, prevents that walking beam 2 from deviating from back horse head 1 bottom together.
