Description

TECHNICAL FIELD

[0001] The utility model relates to the paint removal technical field of locomotive accessories, in particular to a laser paint removal system of locomotive accessories. BACKGROUND

[0002] In the process of locomotive maintenance, the locomotive bogie is usually disassembled first, and then the locomotive accessories are detected. The detected locomotive accessories include traction seat parts, triangular plates, triangular struts, gear box mounting seats, traction rods and motor hangers. The detection method generally adopts flaw detection on the welds and connections of the locomotive accessories to detect the surface and internal defects of the locomotive accessories.

[0003] However, the paint coating on the surface of the locomotive accessories often affects the accuracy of the flaw detection, so it is necessary to perform paint removal on the outer paint film of the locomotive accessories before detection to prepare for subsequent flaw detection.

[0004] Currently, most of the paint removal methods for locomotive parts at home and abroad adopt the following two methods: 1. Chemical paint removal method. The chemical paint removal method needs to apply paint removal agent to the surface of the locomotive accessories, wait for the chemical reaction between the paint removal agent and the paint film, and then clean the paint film with a high-pressure water gun. This paint removal method not only consumes a large amount of water, but also pollutes the health of the workers and the environment because the paint removal agent is a chemical reagent. 2. Sand blasting paint removal method. The sand blasting paint removal method uses compressed air as power to form a high-speed jet to spray sand onto the surface of the locomotive accessories to remove the paint film and other attachments on the surface of the locomotive accessories. This method has problems such as noise pollution and air pollution. In addition, due to the lack of standard process control for sand blasting treatment on the surface of the locomotive accessories, it is impossible to adjust the sand blasting parameters according to the characteristics of the surface of the locomotive accessories, resulting in excessive sand blasting problems, which is a huge waste of energy and materials.
