Abstract
The invention discloses a swing arm for an electrically-driven excavator. The swing arm comprises a main plate and two groups of connecting components which are same in structure, wherein the two groups of connecting components are symmetrically distributed on two sides of the main plate; each connecting component comprises an auxiliary plate and a rotating shaft; each auxiliary plate is connected with the main plate by a reinforcing plate; each rotating shaft is fixedly inserted into the end part of the corresponding auxiliary plate and is vertical to the auxiliary plate; a connecting hole is formed in the lower end of each rotating shaft on the corresponding auxiliary plate; each rotating shaft is positioned on one side, close to the main plate, of the corresponding auxiliary plate; each rotating shaft is provided with a clamping slot. Compared with the prior art, the swing arm disclosed by the invention is simple in structure, low in cost and capable of satisfying the strength requirement of the excavator.
Description
Technical field
The present invention relates to engineering machinery field, be specifically related to the swing arm of a kind of driven by power excavator.
Background technology
Excavator, also known as excavation machinery (excavating machinery), is excavate higher or lower than the material holding machine side with scraper bowl, and loads haulage vehicle or unload the earth moving plant to rickyard.Material mainly soil, coal, silt and the Soil and Rock after pre-pine that excavator excavates.From the development of engineering machinery in recent years, the development of excavator is relatively very fast, and excavator has become one of topmost engineering machinery in engineering construction, but excavator swing arm structure of the prior art is complicated, cost is higher and intensity is unreliable.
