Connecting structure of first rail and second rail

LIU HAO / ZHU HONGZHI

The invention provides a connecting structure of a first steel rail and a second steel rail. The connecting structure comprises the following components: a first steel rail which is a 50kg/m steel rail; a second steel rail which is an 80R steel rail; and a special-shaped joint. One end of the special-shaped joint is connected with the 50kg/m steel rail, and the other end of the special-shaped joint is connected with the 80R steel rail; the 50kg/m steel rail is fixedly connected with the 80R steel rail through the special-shaped joint; the top surface of the 50kg/m steel rail is flush with thetop surface of the 80R steel rail; the end surface, facing a working edge, of the rail head of the 50kg/m steel rail is flush with the end surface, facing the working edge, of the rail head of the 80Rsteel rail. According to the connecting structure provided by the invention, the 50kg/m steel rail and the 80R steel rail are connected by arranging the special-shaped joint, and the stability and the safety during the passage of a train can be guaranteed by reasonably arranging the relative positions of a first connecting section, a transition section and a second connecting section.

本发明供了一种第一钢轨与第二钢轨的连接结构，包括：第一钢轨，为50kg/m钢轨；第二钢轨，为80R钢轨；异型接头，异型接头的一端与50kg/m钢轨相连，异型接头的另一端与80R钢轨相连，50kg/m钢轨与80R钢轨通过异型接头固定连接；其中，50kg/m钢轨的顶面和80R钢轨的顶面齐平，50kg/m钢轨的轨头朝向工作边的端面和80R钢轨的轨头朝向工作边的端面齐平。本发明所提供的连接结构，通过设置异型接头，实现了50kg/m钢轨与80R钢轨的连接，并通过合理设置第一连接段、过渡段和第二连接段的相对位置，能够保障列车通过时的稳定性与安全性。
