Abstract
The utility model discloses a diverging combined connecting rod applied to a reciprocating drilling pump in a petroleum well drilling equipment. The big end connecting rod body and the small end connecting rod body are connected by a detachable connecting mechanism. The detachable connecting mechanism comprises a big end flange arranged at the end part of the big end connecting rod body, a small end flange arranged at the end part of the small end connecting rod body, and the big end flange and the small end flange are fixedly connected by a connecting bolt. The diverging combined connecting rod can better avoid the insufficiency of a reciprocating drilling pump and effectively overcome the disadvantages of the reciprocating drilling pump, the structure of the drilling pump is improved, and the disadvantages of over-large volume and weight in drilling pump design are overcome.
Description
Technical field
The utility model belongs to oil, rock gas probing well equipment manufacturing field, the linkage mechanism of crank-connecting rod reciprocating drilling pump specifically.
Background technique
At present, the connecting rod shank in the connecting rod that reciprocating drilling pump adopted is integrated type (or integral type) structure, and all-in-one-piece advantage is that connecting rod shank self is made simple, easy for installation; But deficiency is because connecting rod integral formula physical dimension is relatively large, install to send into or dismantle at connecting rod (first-class) and break away from the drilling pump frame process with bent axle, pump cross, because the influence in mounting point and space, can cause the volume and weight of whole drilling pump to increase, especially for multi-cylinder (five cylinders or more than), high-power, long stroke drilling pump, it is more outstanding that this problem shows, not only increased the whole manufacture cost of drilling pump, because product is subjected to the influence of weight, external dimension, many difficulties have been brought simultaneously to packing of product transportation.
Summary of the invention
The utility model purpose is a kind of reciprocating drilling pump of design separate assembling connecting rod, to overcome the existing relatively large defective of connecting rod integral formula physical dimension.
Specifically, a kind of reciprocating drilling pump separate assembling connecting rod adopts detachable bindiny mechanism to connect between its big end link body and the small end connecting rod shank.
The utility model main feature is to adopt detachable bindiny mechanism to connect between the big end link body of connecting rod and the small end connecting rod shank, and detachable bindiny mechanism connects and can adopt multiple mode to realize based on existing technological means.The detachable bindiny mechanism that the utility model is recommended adopts the flange bolt Placement, it comprises the big end flange that is positioned at big end link end of body, the little end flange that is positioned at small end connecting rod shank end, and is fixedly connected with connecting bolt between big end flange and the little end flange.The bolt quantity of adpting flange can be 2,4,6 and many.Certainly, flange also can adopt other Placement to connect.
The utility model separate assembling connecting rod can be good this not foot phenomenon that exists of solution reciprocating drilling pump, its mounting type can adopt the small end connecting rod shank to be connected with crosshead to put earlier in people's Rack Body, to be assembled into big end link body on the bent axle then lifts the inboard relevant position of frame and carries out with the mode of small end connecting rod shank connection, effectively overcome the deficiency that reciprocating drilling pump exists, improve the drilling pump structure, reduced deficiencys such as the volume, the weight that exist in the drilling pump design is bigger than normal.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the plan view of Fig. 1.
Figure number explanation: 1, big end link body; 2, big end flange; 3, little end flange; 4, small end connecting rod shank; 5, connecting bolt.
Embodiment
Accompanying drawing 1,2 has provided the utility model embodiment.Be exactly with drilling pump connecting rod tip and small end split design specifically, the drilling pump connecting rod of a kind of new structure form that recombinant connects in the drilling pump assembling process, as shown in the figure, the separate assembling drilling pump is made up of main parts size such as big end link body 1, big end flange 2, small end flange 3, small end connecting rod shank 4 and connecting bolts 5 with connecting rod.Fixedly connected between big end flange 2 and the small end flange 3 with connecting bolt 5.
The working procedure of this model utility is: earlier small end connecting rod shank 4 and crosshead are connected, put it into Rack Body inside, then big end link body 1 is lifted the inboard relevant position of frame and align with small end connecting rod shank 4, with connecting bolt 5 big end flange 2 is connected with small end flange 3 gets final product together again; In like manner, when in processes such as maintenance, needing, earlier connecting bolt is removed, respectively the lifting in the drilling pump frame of large and small two ends is taken out then and get final product from drilling pump frame dismounting connecting rod.
Claims (3)
1, a kind of reciprocating drilling pump separate assembling connecting rod is characterized in that adopting between big end link body (1) and the small end connecting rod shank (4) detachable bindiny mechanism to connect.
2, reciprocating drilling pump according to claim 1 separate assembling connecting rod, it is characterized in that detachable bindiny mechanism comprises the big end flange (2) that is positioned at big end link body (1) end, the little end flange (3) that is positioned at small end connecting rod shank (4) end, fixedly connected between big end flange (2) and the little end flange (3) with connecting bolt (5).
3, reciprocating drilling pump according to claim 2 separate assembling connecting rod, the bolt quantity of its feature adpting flange can be 2,4,6 and many.
