Embodiment Construction
[0054] The laser processing equipment involved in the present invention consists of two parts: a laser processing vehicle and a power system container. The laser processing vehicle is small in size and light in weight. There are many ways to realize it. It can complete various strengthening and toughening treatment tasks on the surface of the rail without dismantling the rail. The relatively large volume and weight of equipment such as generators, refrigerators, air compressors, cold dryers, and laser high-voltage power supplies are integrated to form a power system. In order to ensure the high mobility of the laser processing vehicle and meet the processing needs of rails in different environments, the power system is installed in the container body to form a power system container. The container is installed on a truck to form a power engineering vehicle, which can meet the requirements of online laser processing of railroad rails in the field; it can also be installed on a ...

Abstract
The invention discloses an on-line laser processing equipment used for strengthening and toughening of the surface of a steel rail, comprising a laser processing lathe and a power system container. The laser processing lathe comprises a motion actuating mechanism, a laser processing head and / or a control system and a powder feeder which are arranged on a moving cart; and the power system container comprises a power generator, a refrigerator, an air compressor, a cool drying machine and a high-voltage power supply of a laser which are arranged in the container. The laser processing head can be arranged on the motion actuating mechanism and is directly connected with the laser or connected with the laser by a light-guiding system. The invention can complete the laser surface quenching, fused quenching, alloying and cladding treatment of various steel rails which comprises a stock rail, a curve, a guide rail, a switch and the like under the premise that the steel rail is not dismounted and the normal running of trains, thus leading the wear resistance of the processed steel rail to be improved greatly and having the characteristics of simple assembly and disassembly, high processing precision and simple operation and control.
Description
technical field [0001] The invention belongs to the technology of surface strengthening and repairing, and relates to an online laser processing equipment for strengthening and repairing the surface of rails, and is especially suitable for the strengthening and toughening of rails on railways, subways and light rails. Background technique [0002] With the increase of train speed, capacity and axle load, the rate of rail failure due to wear is getting faster and faster, and train derailment accidents caused by rail damage occur from time to time. The direct cost of replacing and repairing damaged steel rails in our country amounts to billions of yuan every year. [0003] High-speed and heavy-duty trains have higher requirements for train running stability and safety, and better wear resistance and longer service life of steel rails are one of the key factors. For ordinary railway lines, rail damage mainly manifests as hole cracks, vertical and horizontal cracks on the rail ...
