Abstract
The utility model provides a bucket lug plate structure of an excvavtor. The bucket lug plate structure comprises a lug plate, a top plate and an arc plate, wherein the lug plate extends to the arc plate from the top plate. The bucket lug plate structure has the beneficial effects that the stress condition is improved through the lengthened lug plate, the intensity of the lug plate and the arc plate is further enhanced through a pad plate and plug welding seams, the cracking rate of the lug plate is reduced, and the service life of the bucket is prolonged.
Description
Technical field
The utility model relates to a kind of power shovel otic placode structure, belongs to the power shovel field.
Background technology
Scraper bowl is the parts that directly contact with material on the excavator, has born very large impact force, and the afterbody of otic placode is easy to take place cracking and waits destruction.As shown in Figure 1, the otic placode structure of scraper bowl in the prior art, otic placode integral body is positioned on the top board, and otic placode and top board only depend on fillet weld to link.The bond sites of otic placode and top board is stressed very big, but only depends on fillet weld to link between them, so otic placode very easily takes place by destructions such as cracking.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of power shovel otic placode structure, has improved the force-bearing situation of otic placode, has reduced the cracking rate of otic placode, has prolonged the application life of scraper bowl integral body.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of power shovel otic placode structure, comprise otic placode, top board and arc plate, and otic placode extends to the arc plate from top board.
Preferably, the junction of otic placode and arc plate is provided with backing plate.
Preferably, otic placode, arc plate and backing plate are linked by plug weld and fillet weld.
The beneficial effect of the utility model is: the otic placode of prolongation has improved force-bearing situation, and backing plate and plug weld have further strengthened otic placode and arc plate intensity, has reduced the cracking rate of otic placode, has prolonged the application life of scraper bowl.
Description of drawings
Fig. 1 is a prior art scraper bowl otic placode structural representation;
Fig. 2 is the structural representation of the utility model.
Among the figure: 1, otic placode, 2, top board, 3, the arc plate, 4, backing plate, 5, plug weld and fillet weld.
The specific embodiment
To combine accompanying drawing that the utility model is described further below.
As shown in Figure 2, a kind of power shovel otic placode structure comprises otic placode 1, top board 2 and arc plate 3, and otic placode 1 extends to arc plate 3 from top board 2; The junction of otic placode 1 and arc plate 3 is designed with backing plate 4; Otic placode 1, arc plate 3 and backing plate 4 are linked by plug weld and fillet weld 5.
The structure of the utility model during splicing, is positioned over otic placode 1 on top board 2 and the arc plate 3, and backing plate 4 is positioned on the arc plate 3, forms uniform plug weld between backing plate 4 and the otic placode 1; During welding, full the plug weld weldering earlier between backing plate 4 and the otic placode 1, on the basis of plug weld, weld fillet weld again, all the other each bond sites welding fillet welds.
Adopt this structure; Otic placode 1 stressing conditions that prolongs is relatively good; Backing plate 4, plug weld and fillet weld 5 have further strengthened otic placode 1 and arc plate 3 intensity again, even scraper bowl receives very big impact force like this, otic placode 1 still has good stressing conditions; Reduce the cracking rate of otic placode 1, prolonged the application life of scraper bowl integral body.
