Rebar rust removal trolley for construction site

Abstract

The invention discloses a rebar rust removal trolley for a construction site. The rebar rust removal trolley comprises a base, a rust removal bucket and a driving gear. The rust removal bucket is internally provided with a polishing layer, a cleaning layer and a drying layer which are sequentially arranged in the rebar feeding direction. The polishing layer is of a round ring structure and is internally and symmetrically provided with four slide grooves, a connection rod is slidably installed in each slide groove, one end of each connection rod is fixedly connected with the inner wall of the polishing layer through a spring, and the other end of the connection rod is rotationally provided with a polishing ball. The cleaning layer is also of a round ring structure, and a cleaning disc is arranged in the middle of the cleaning layer. According to the rebar rust removal trolley provided by the invention, the rust removal bucket is internally provided with the polishing layer, the cleaning layer and the drying layer, the structure is simple, using is convenient, and carrying and transporting are facilitated; and moreover, rebars can be effectively polished, cleaned and dried, and the rust removal effect is excellent.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a steel bar derusting trolley for construction sites. Background technique [0002] A steel bar is a strip of steel, a type of building material. For example, in reinforced concrete, the skeleton used to support the structure. Including plain round bars, ribbed bars, twisted bars. There are many types of steel bars, usually classified by chemical composition, production process, rolled shape, supply form, diameter, and use in structures. Steel bars mainly bear tensile stress in concrete. Due to the effect of the ribs, the deformed steel bar has a greater bonding capacity with the concrete, so it can better withstand the external force. Steel bars are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures. [0003] When the steel bar is placed for a long time, a large amount of rust is likely to ...

AI Technical Summary

Problems solved by technology

[0003] When the steel bar is placed for a long time, a large amount of rust is likely to be generated on its surface, which affects the use of the steel bar; the existing steel bar rust removal is generally carried out by manual grinding or using a descaling machine. Manual grinding is not only high in labor costs, but also time-consuming and laborious. However, the existing derusting machines are generally large in size and inconvenient to transport, which is not conducive to the derusting of steel bars at the construction site.
