Abstract

The invention discloses a portable steel rail laser rust removal device and a rust removal method. The laser rust removal device generally comprises an operating rod, a laser head assembly and a supporting structure. Compared with a conventional rust removal method, the portable steel rail laser rust removal device does not need to use any chemical agent and cleaning fluid, cleaned waste materials are basically solid powder, the size is small, storage is easy, recycling can be achieved, and the problem of environmental pollution caused by chemical cleaning can be easily solved.

Description

technical field [0001] The invention relates to the technical field of derusting rails, in particular to a portable laser derusting device for rails. Background technique [0002] At present, the commonly used derusting methods in China include mechanical grinding, flame derusting, electric spark derusting, shot blasting (sand) derusting, and chemical treatment derusting. Mechanical grinding and derusting mainly use tools such as grinding wheels to clean the rusted parts of the rail, which is labor intensive and the quality of derusting is poor. Flame derusting is to use a gas torch to burn a small amount of deep rust spots that are difficult to remove by hand, and let the high temperature change the chemical composition of the rust oxides to achieve the purpose of derusting. This method is easy to damage the rail surface and cause the rail surface to be deformed by heat. Shot blasting is to remove the rust on the surface of the rail by spraying abrasives of different part...
