Description

Technical Field

[0001] This utility model relates to auxiliary tools for railway locomotive maintenance operations, specifically a track crossing plate used for crossing railway inspection pits and locomotive end coupler maintenance operations. Background Technology

[0002] Track crossings are the most frequently used auxiliary tools in railway locomotive maintenance operations. Since most of the crossings currently in use are made of iron, they have several defects: they are prone to rusting and deformation over time, and they corrode and age during outdoor use.

[0003] Moving the work site is inconvenient. The existing crossbeams are designed to match the track gauge and dimensions. When changing work sites, they cannot be moved due to the influence of the rail fasteners. Even if the dimensions are modified in the design to allow for movement, the crossbeams are prone to shifting when stepped on, posing a safety hazard to workers. Metal products are conductive and may emit a red glow. In winter, they may freeze during snowfall, posing a safety hazard to workers traveling to and from the site. Utility Model Content
