Abstract
Description
Technical Field
[0001] This utility model relates to the field of track maintenance technology, specifically a railway track maintenance and cleaning device. Background Technology
[0002] As the core infrastructure of the railway transportation system, railway tracks operate under complex environmental conditions for extended periods. Under repeated train loads and the influence of the natural environment, the surface of I-beam cross-section rails easily accumulates pollutants such as oil, rust, and ballast debris. These surface deposits not only accelerate the corrosion process of the rails but also alter wheel-rail contact characteristics, affecting train operation safety. Current industry standards require regular track surface maintenance to ensure the integrity of the track structure and the smoothness of train operation.
[0003] Traditional manual cleaning methods have significant technical limitations: relying on physical scraping with handheld wire brushes results in low cleaning efficiency and uneven effects, making it difficult to thoroughly remove stubborn contaminants from complex areas such as the rail web and rail base; at the same time, manual maintenance is inefficient. Therefore, we propose a railway track maintenance and cleaning device. Utility Model Content

[0026] The working principle of the railway track maintenance and cleaning device provided by this utility model is as follows: In use, the track gauge is first adjusted via the moving component 5: the first motor 54 drives the bidirectional screw 53 to rotate, causing the two moving blocks 52 on both sides to slide in opposite directions, so that the spacing between the moving wheels 56 on the connecting frame 55 is synchronously adjusted to match the width of the rail.

Metal grinding wire 85 is closely attached to the curved surface of the rail web, and the third motor 83 drives the rotating wheel to achieve fine cleaning of the rust layer on the rail web and sides. During the operation, the liquid injection component 9 works simultaneously: the liquid pump 93 atomizes the rust removal liquid in the storage tank 91 and sprays it evenly onto the rail surface through the spray pipe 73 to soften the oxide layer and reduce grinding resistance. When the device moves along the rail by the push frame 4, the moving wheel 56 drives the entire equipment to move forward. Each grinding unit and spraying unit work together continuously to achieve integrated cleaning and rust removal of the entire circumference of the rail. The entire system achieves multi-module linkage control through the control switch group 3 to ensure the automation and efficiency of the operation process.
