Polishing device for cast iron well grate

Abstract

The invention relates to a polishing device for a cast iron well grate. The polishing device comprises a protection mechanism, a supporting mechanism, a conveying mechanism and a polishing assembly. The supporting mechanism is arranged in the middle of the protection mechanism, the conveying mechanism is arranged in the protection mechanism, and the polishing assembly is arranged on the protectionmechanism. According to the polishing device for the cast iron well grate, the conveying mechanism is used for conveying the cast iron well grate, the polishing assembly is used for polishing the cast iron well grate while the cast iron well grate is conveyed, the polishing efficiency is greatly improved, and in the polishing process, a protective cover of the protection mechanism is used for protection, so that scrap iron is prevented from flying out from the side edge, scrap iron falls to the lower portion of the protective cover along the inner wall of the protective cover under blocking of the protective cover after being brushed away by a polishing brush, workers can be prevented from being hurt by the scrap iron brushed away by the high-speed polishing brush, and therefore the safety performance of the polishing device is effectively improved; and the cast iron well grate can be more comprehensively polished through a polishing mechanism, so that the polishing quality and the polishing efficiency can be effectively improved, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention belongs to the field of casting processing, and in particular relates to a grinding device, in particular to a grinding device for a cast iron well grate. Background technique [0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into the pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, it is polished and other subsequent processing methods , the obtained objects have a certain shape, size and performance. Cast iron grate is one of the more widely used castings. Cast iron grate is also a manhole cover, which is used to cover roads or deep wells in homes to prevent people or objects from falling. It can be used for greening Belts, sidewalks, motorways, piers, alleys, etc. [0003] The cast iron well grate can be used after being processed and formed, among which grinding is a relatively important procedure. Most of the existi...
