Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of excavators, in particular to a reinforced excavator boom. Background Art
[0002] The boom of an excavator is an important component that connects the bucket and the body of the excavator. It is usually made up of multiple steel arms and can be flexibly extended and rotated. It undertakes the important tasks of excavation, grabbing and handling operations, and the angle and length can be adjusted according to work needs. The boom is equipped with hydraulic cylinders and hydraulic pipelines, which are driven by the hydraulic system to provide powerful power and precise control. In the fields of engineering construction, mining, etc., the boom of an excavator is widely used. It is a core component of heavy machinery and carries important operating functions and efficiency requirements.
[0003] Most of the existing excavator booms are solid. Solid excavator booms are heavy and have poor performance. Hollow excavator booms have low overall strength. When the excavator boom is hit by external force, the excavator boom is prone to dents, causing damage to the excavator boom. The service life of the excavator boom is average. Therefore, we propose a reinforced excavator boom. Utility Model Content
[0004] The purpose of the utility model is to provide a reinforced excavator boom to solve the problems raised in the above background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A reinforced boom for an excavator comprises an excavator boom body, wherein an upper transverse reinforcing rib and a lower transverse reinforcing rib are respectively welded to the top and bottom ends of an inner cavity of the excavator boom body, a reinforcing filling layer is filled between the upper transverse reinforcing rib and the lower transverse reinforcing rib, and a plurality of groups of vertical reinforcing ribs are vertically connected inside the upper transverse reinforcing rib and the lower transverse reinforcing rib.
[0007] Furthermore: each group of vertical reinforcement ribs is connected with the upper transverse reinforcement ribs and the lower transverse reinforcement ribs with anchor nails.
[0008] Furthermore, the outer wall of the excavator boom body is also equipped with a boom cylinder ear plate and a dipper rod cylinder ear plate.
[0009] Furthermore: mounting seats are provided at both ends of the excavator boom body, and connecting holes are opened in the mounting seats.
[0010] Furthermore: the two ends of each group of vertical reinforcing ribs are respectively welded to the top wall and the bottom wall of the inner cavity of the excavator boom body.
[0011] Further: the outer surface of the excavator boom body is coated with an anti-corrosion layer and a wear-resistant coating.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The utility model improves the overall strength of the excavator boom through upper transverse reinforcement ribs, lower transverse reinforcement ribs and a reinforcement filling layer, reinforces the connection between the upper transverse reinforcement ribs, lower transverse reinforcement ribs and the reinforcement filling layer through multiple groups of vertical reinforcement ribs, and reinforces the connection between the vertical reinforcement ribs and the upper transverse reinforcement ribs and lower transverse reinforcement ribs through anchor nails, thereby improving the strength of the excavator boom from multiple directions, making the excavator boom less prone to damage and extending its service life. While improving the strength of the excavator boom, the weight of the excavator boom is reduced, and the practicality of the excavator boom is improved. BRIEF DESCRIPTION OF THE DRAWINGS
