[0002] Reinforcement plates are also called Stiffeners, reinforcement plates, reinforcement plates, support plates, reinforcement plates, and reinforcement ribs. Reinforcement plates are mainly used in construction, oil pipelines, mechanical equipment, electronic products, etc. They are widely used in FPC flexible circuit boards in electronic products. Reinforcement plates mainly solve the flexibility of flexible circuit boards, improve the strength of the plug-in parts, and facilitate the overall assembly of products. In excavator equipment, reinforcement plates are usually used to strengthen the excavator boom to avoid damage to the boom caused by stress concentration.

[0003] The prior art has the following shortcomings: Application No. 202022571780.9 in the prior art proposes a reinforced structure for a new energy-saving hydraulic excavator boom, including a reinforced structure body, the reinforced structure body includes left and right side plates, upper and lower cover plates, a boom cylinder support and a reinforcement plate, the upper and lower cover plates include an upper cover plate and a lower cover plate, the upper cover plate and the lower cover plate are respectively arranged at the upper and lower ends of the left and right side plates, a reinforcement plate is welded on the lower cover plate, and the boom cylinder support is installed on the integrated frame-type closed structure composed of the left and right side plates and the upper and lower cover plates. The reinforcement plate is welded to the lower cover plate, which can strengthen the frame-type closed structure. It has a very strong bearing capacity when working under special harsh working conditions, and has small elastic deformation, which can prevent the excavator boom from stress concentration after being subjected to a large impact load. The overall structure has high rigidity, which can avoid fatigue cracking of the structure and adapt to various working conditions.

At the same time, the reinforcing effect provided by the reinforcing plate is single, and it only strengthens the corresponding position through its own strength. The overall strengthening effect of the upper arm can be further improved. Utility Model Content
