Unloading track for port transportation

The invention relates to an unloading rail for port transportation, in particular to the technical field of cargo transportation. The unloading track provided by the invention comprises the first transportation assembly, the second transportation assembly and the like, meanwhile, the shock absorbers are additionally arranged below the first transportation assembly and the second transportation assembly, and by arranging the shock absorber parts, the shock force borne by the first transportation assembly and the second transportation assembly above is reduced, and the bumping influence caused when a floating bridge is impacted by sea waves is reduced. A first auxiliary wheel, a push rod assembly and other parts are further arranged on the second conveying assembly, the first auxiliary wheel is not prone to deviation when affected by the impact effect of water flow, it is ensured that the first auxiliary wheel can be always attached to the conveying belt through the push rod assembly, and then it is ensured tha
