Description
Technical field
The utility model relates to a kind of oil pumping machine crank and connecting rod repair structure.
Background technique
Crank, connecting rod are the vitals of beam pumping unit, are also easily damaged partss.In pumping unit working procedure, fastening nuts is not in place due to the nut loosening on crank and link connector pin axle or when installing, attachment hole in easy generation crank body or on con-rod only is ground large or is worn into oval situation, this not only makes pumping unit work, and causes very large loss to field produces.If process the crank that more renews and connecting rod, need ironcasting 500 ~ 1000 kilograms, and need milling, Bao, insert, the multiple working procedure such as boring, the process-cycle is long, and cost is high.
Model utility content
Goal of the invention of the present utility model is to provide a kind of oil pumping machine crank and connecting rod repair structure, convenient to crank, connecting rod reparation, effectively reduces costs low, the reduction of erection time.
Based on same inventive concept, the utility model has two independently technological schemes:
1, a kind of oil pumping machine crank repair structure, crank body is provided with the attachment hole for being connected with connecting rod, pin tapered sleeve is provided with in attachment hole, it is characterized in that: in attachment hole, be also provided with rigidized cover, rigidized cover is positioned at the outside of pin tapered sleeve, rigidized cover and pin tapered sleeve, attachment hole inwall drive fit, rigidized cover and crank body are bolted.
Rigidized cover is steel bushing, and rigidized cover two ends are fixed by bolt and crank body, and rigidized cover is often held and fixed by 3-4 bolt and crank body, and bolt position is along the circumferential direction uniformly distributed.
2, a kind of pumping unit connecting bar repair structure, con-rod only is provided with the attachment hole for being connected with crank, pin tapered sleeve is provided with in attachment hole, it is characterized in that: in attachment hole, be also provided with rigidized cover, rigidized cover is positioned at the outside of pin tapered sleeve, rigidized cover and pin tapered sleeve, attachment hole inwall drive fit, rigidized cover and con-rod only are bolted.
Rigidized cover is steel bushing, and rigidized cover two ends are fixed by bolt and con-rod only, and rigidized cover is often held and fixed by 3-4 bolt and con-rod only, and bolt position is along the circumferential direction uniformly distributed.
The beneficial effect that the utility model has:
The utility model only need carry out reaming to the attachment hole in crank body or con-rod only, inlays into rigidized cover, can realize the reparation of crank or connecting rod, significantly reduce rehabilitation cost, shortens and repairs the duration.The utility model rigidized cover is steel bushing, and rigidized cover two ends are fixed by bolt and crank body or con-rod only, efficiently solves two kinds of problems that unlike materials welding is difficult or weld strength is not enough, ensures repairing effect further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1.
Embodiment
Embodiment 1: oil pumping machine crank repair structure
As shown in Figure 1, crank body 1 is provided with the attachment hole for being connected with connecting rod, is provided with pin tapered sleeve 4 in attachment hole, and this is prior art.Also be provided with rigidized cover 2 in attachment hole, rigidized cover 2 is positioned at the outside of pin tapered sleeve 4, rigidized cover 2 and pin tapered sleeve 4, attachment hole inwall drive fit, and as shown in Figure 1, rigidized cover 2 is fixed by bolt 3 with crank body 1.During enforcement, rigidized cover 2 is steel bushing, and as shown in Figure 1 and Figure 2, rigidized cover 2 two ends are fixed by bolt 3 and crank body, and in the present embodiment, rigidized cover is often held and fixed by 4 bolts and crank body, and 4 bolt positions are along the circumferential direction uniformly distributed.
Add man-hour, first the attachment hole of crank body 1 is carried out reaming, one side reaming 3mm ~ 6mm, according to the external diameter of the attachment hole internal diameter determination rigidized cover 2 after reaming, according to the internal diameter of the external diameter determination rigidized cover 2 of pin tapered sleeve 4, be bumped in attachment hole by the rigidized cover 2 processed, rigidized cover 2 and crank body 1 between pin tapered sleeve 4 and attachment hole inwall, then are fixed by bolt 3 by rigidized cover 2.
Embodiment 2: pumping unit connecting bar repair structure
By in embodiment 1 crank body replace become con-rod only, remaining structure and working principle identical with embodiment 1.
