Train wheel set laser cleaning machine and train wheel set cleaning method

Abstract

The invention provides a train wheel set laser cleaning machine. A train wheel set laser cleaning device is arranged in a cleaning room; the cleaning room is provided with a left lifting door and a right lifting door for achieving the effects of safety protection and smoke closing; and the cleaning device comprises a truss, a wheel set limiting driving unit, a waste discharge unit and a wheel set cleaning unit slidingly connected with the truss. The train wheel set laser cleaning machine adopts laser cleaning as a main cleaning mode to achieve high cleaning efficiency; through no grinding and no contact in the laser cleaning, the surfaces of wheel sets cannot be damaged, and the secondary pollution cannot be generated; the laser cleaning is matched with a manipulator to achieve high automation degree and to reduce the labor cost; any chemical reagent and cleaning liquid have no need to use; wastes generated by cleaning are powder; and the powder is small in size and capable of recovering, so that the environmental pollution problem cannot be generated.

Description

technical field [0001] The invention relates to the technical field of train wheel set cleaning equipment, in particular to a train wheel set laser cleaning machine and a train wheel set cleaning method. Background technique [0002] With the rapid development of railway train technology, the speed of trains has been increased in recent years, so the performance requirements of each part of the train have been correspondingly increased. The vehicle wheel set is an important part of the train operation. It consists of two left and right wheels firmly pressed on the same axle. The role of the wheel set is to ensure the running and turning of the train on the rails, bear all the static and dynamic loads from the train, transfer it to the rails, and transfer the load caused by uneven lines to one of the parts of the train. It is one of the most critical control points to determine the safety of train running. Therefore, in the maintenance process of the train, the requirements...

AI Technical Summary

Problems solved by technology

Due to the long-term operation of the wheel set, except for the treads and rims that are in contact with the rails, the rest of the parts exposed to the air will be corroded to varying degrees. the accuracy of

[0004] At present, the derusting methods for wheel sets are mainly mechanical derusting method, liquid and solid strong impact cleaning and chemical corrosion cleaning. On the wheel, the wheel is driven by the wheel to roll axially in situ. At the same time, the cantilever wire brush protruded from the descaling machine is pressed against the wheel shaft to rotate at high speed and move laterally. Friction will brush off the rust attached to the axle to achieve the purpose of rust removal. This method is contact cleaning, which has mechanical force on the cleaning surface and damages the axle surface; or the cleaning medium is attached to the axle surface, which is prone to secondary secondary pollution

Patent No. 201210165880.9 discloses a method of derusting and cleaning the wheels of railway locomotives. The derusting and cleaning of the wheels can be realized by using the sand-containing water sprayed by the high-pressure water sandblasting gun. The derusting effect is good, but this method A large amount of sand will be generated, which is difficult to clean; and the high-pressure water sandblasting gun will damage the train wheels during the cleaning process

Chemical corrosion cleaning uses chemicals and cleaning fluids to clean, which produces a large amount of cleaning waste and causes environmental pollution.
