Abstract

The invention provides a brush frame assembly. The brush frame assembly comprises a lower bottom plate assembly, wherein the lower bottom plate assembly comprises a lower bottom plate and a pluralityof first brush frame assemblies; the plurality of first brush frame assemblies are welded on the bottom plate; the lower bottom plate comprises a plurality of concave plates and a plurality of archedbosses, wherein the plurality of concave plates and a plurality of convex plates are connected together in a staggered mode, and the plurality of bosses are located on the same side of the concave plates; and the first brush frame assemblies are welded to the arc top parts of the bosses. According to the brush frame assembly, the first brush frame assemblies are welded to the arc top parts of thebosses, and after being pressured, the bosses are deformed to relieve pressure, and high compression strength is achieved, so that damage to the first brush frame assemblies and brush boxes for covering the first brush frame assemblies caused by compression can be avoided.
