Abstract
The utility model provides an excavator large-arm cover plate which comprises two straight plates and an arc-shaped plate. The two straight plates are welded at the two ends of the arc-shaped plate respectively, and the welding parts of the two straight plates and the arc-shaped plate are in smooth transition. The excavator large-arm cover plate has the advantages that the technology for manufacturing large-arm cover plates is simplified and manufacturing cost is lowered.
Description
Technical field
The utility model belongs to the plant equipment field, especially relates to a kind of big arm of digger cover plate.
Background technology
The big arm of digger cover plate is all integrated structure in existing technology, and the large arm cover plate of this structure need to be processed with large hydraulic press, has that difficulty of processing is large, processing cost high-technology problem.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of big arm of digger cover plate, especially is fit to monthly output lower middle-size and small-size plant equipment processing enterprise.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of big arm of digger cover plate, it is characterized in that: comprise two straight plates and an arc, two described straight plates are welded in respectively the two ends of described arc, and the position of two described straight plates and the welding of described arc seamlessly transits.
The radius R of described arc circular arc is 2500mm.
On two described straight plates is not or not L is 4m with the air line distance of the end of described arc welding.
The length summation of the arc length of described arc and two described straight plates is 6m.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, simplified the processing technology of large arm cover plate, reduced processing cost, improved the mechanical strength of large arm cover plate, can save material during maintenance.
