Abstract

The invention relates to a heel structure of a tramway turnout point rail which not only ensures the safety, reliability and stability of the heel end of the switch rail, but also is convenient for installation and quick disassembly. Inside the tongue opening on one side, the bolt passes through the bolt hole in the upper boss on one side of the table, the spacer iron and the bolt hole of the basic rail body to connect the basic rail and the table as a whole; the bottom surface of the point rail is inserted into the other side of the table The tongue groove on the inner side of the upper boss and the tongue and groove clamping surface match the bottom surface of the switch rail, the positioning pin is embedded in the positioning pin slot in the middle of the table, and the side of the positioning pin is closely adjacent to the side surface of the bottom surface of the switch rail, and the bolt passes through Fix the positioning pin and the platen through the threaded connection between the positioning pin and the screw hole of the bolt in the platen. Advantages: It not only ensures the safety, reliability and stability of the heel of the switch rail, but also facilitates quick disassembly, and the construction efficiency is high.
