Description
Technical field
The utility model relates to a kind of locomotive whole-vehicle cleaning apparatus.
Background technology
Motor washer presses cleaning way, can be divided into Contactless car washing machine and Brush type motor washer two class.The defects such as Brush type motor washer, due to the mechanical specialities of hairbrush, creates groove and do not wash clean, hairbrush meeting worn-out surface paint.Contactless car washing machine adopts high pressure jet, or steam carwash, there is not groove and does not wash clean the problem with worn-out surface paint.From cleaning performance and operation, in-use performance is seen, Contactless car washing machine is more advanced than Brush type motor washer.
The tractor equipment that electric locomotive transports as railway traffic, stock on hand is very huge, corresponding, its maintenance, and the work capacity of maintenance is also abnormal huge.Generally before locomotive inspection and repair or maintenance, first to clean it, so that pinpoint the problems and looking up the fault, also maintain easily repairing.
For electric locomotive, because its volume is comparatively large, the amount of parts being arranged on locomotive surface is many, causes its surface irregularity, is difficult to realize mechanization, and automation is cleaned.
