Aluminum alloy rail with buffer protection mechanism

The utility model relates to the technical field of buffer protection mechanisms, in particular to an aluminum alloy track with a buffer protection mechanism, which comprises an elastic piece, a water chute and a rubber sleeve, and has the beneficial effects that the elastic piece and a bearing plate are arranged to drive an upper protection cover to descend and the elastic piece to be compressed, so that the impact force is reduced, and a train is ensured to pass stably; symmetrical water guiding grooves are formed in the left end and the right end of a containing groove of the lower protective cover respectively, rainwater is led out through the water guiding grooves, corrosion of the rainwater to an elastic piece is reduced, a spring is arranged in a gap between an inserting rod and an inserting groove, the spring is prevented from being corroded by the rainwater, the service life of the spring is prolonged, a rubber sleeve is connected with a rubber block in an inserted mode, and the service life of the s
