Background

The locomotive is a self-propelled vehicle which pulls or pushes a railway vehicle to run and does not load business load per se, and is commonly called a locomotive. Locomotives are land vehicles that consume the least amount of energy, as calculated by the amount of fuel consumed per ton of kilometer transported, and are typically driven directly or through a transmission by a steam engine, diesel engine, gas turbine, traction motor, or other power machine. The power machine makes the driving wheel of the locomotive generate moment, and the road gives the driving wheel with reaction force with equal magnitude and opposite direction. The sum of the individual wheel reaction forces is referred to as the locomotive tractive effort. This traction force is a tangential external force generated by the forces acting on the moving wheel rim and is also called wheel rim traction force.

The existing locomotive cable is installed in a train, and in the long-time running process, the locomotive cable can be continuously contacted with substances such as steel materials and the like, so that the locomotive cable is easy to wear, the locomotive cable is usually hidden at the position of a shielding object after the outer wall of the locomotive cable is worn, the slightly damaged position is not easy to find when a railway worker regularly checks, and the locomotive cable has serious potential safety hazard when being used again.
