[0002] During operation, railway locomotives experience gradual wear, corrosion, and damage to their components. To ensure locomotives are always in good condition, guarantee safe operation, and extend their service life, various inspections and repairs are essential. Implementing assembly line operations helps reduce repair costs and improve maintenance quality and labor productivity. In the current railway locomotive maintenance system, most maintenance is performed after the locomotive is parked at a fixed location. However, if anti-slippage measures are inadequate when maintenance is needed, locomotives are prone to slippage accidents, threatening the lives of personnel.
[0003] In the prior art, application number 202321404054.5 discloses a railway locomotive maintenance anti-slippage device, including an anti-slipper. The inner walls on both sides of the anti-slipper are movably connected to the two ends of the outer wall of the connecting rod, and the middle part of the outer wall of the connecting rod is movably connected to the inner wall of the buffer block. The anti-slipper of the above device is set on the rail, and the bottom side of the inner wall of the anti-slipper is higher than the upper surface of the rail. When the locomotive wheel enters the interior of the anti-slipper, a drop will occur, causing the locomotive wheel to be dragged.
