Abstract

The invention relates to a tramcar turnout point rail heel structure capable of guaranteeing the safety, reliability and stability of a point rail heel and convenient to install and detach quickly. A platen is located on a cushion plate. A rail bottom face of a stock rail is inserted in a downward-pressing tongue-shaped opening in one side of the bottom of the platen. A bolt penetrates a bolt via hole in a boss at the upper portion on one side of the platen, a spacer block and a bolt hole of a rail body of the stock rail so that the stock rail and the platen can be connected into a whole. A rail bottom face of a point rail is inserted in a tongue-shaped groove in the inner side of a boss at the upper portion on the other side of the platen, the tongue-shaped groove clamping face is matched with the rail bottom face of the point rail, a locating pin is embedded in a locating pin embedding groove in the middle portion of the platen, the side face of the locating pin tightly leans against the side face of the rail bottom face of the point rail, a bolt penetrates the locating pin to be screwed into a bolt screwing thread hole in the platen, and therefore the locating pin and the platen are fixed. The tramcar turnout point rail heel structure has the beneficial effects that the safety, reliability and stability of the point rail heel are guaranteed, detaching can be conducted rapidly and conveniently, and the construction efficiency is high.
