Abstract

The invention discloses an improved special-shaped joint of a grooved rail and a processing method of the special-shaped joint, and relates to the field of rails. The improved special-shaped joint comprises a grooved rail section, a transition section and an I-rail connection section, wherein the grooved rail section, the transition section and the I-rail connection section are equal in thicknessof rail lips; the shape and height of a rail head of the grooved rail section are the same as that of the grooved rail; the width of a rail groove of the I-rail connection section is greater than thatof the grooved rail section; a rail groove of the transition section smoothly transitions to connect the rail groove of the I-rail connection section with a rail groove of the grooved rail section; and the I-rail connection section is in welded connection with an I-rail. The improved special-shaped joint of the grooved rail can guide wheels to smoothly enter and move along a working side of the grooved rail, thereby improving the stability and safety of vehicle running during the wheel-rail transition and maintaining the protection function of the rail lips.

Description

technical field

[0001] The invention relates to the field of rails, in particular to an improved grooved rail special-shaped joint and a processing method thereof. Background technique

[0002] Prioritizing the development of public transportation is an important transportation development strategy in my country. As a middle-level public transportation system, modern trams have become an inevitable trend in the development of public transportation with its humanized, large-capacity, environmental protection, energy-saving, and modern features.

[0003] In the track system of modern trams, the main line mainly adopts grooved steel rails. Under the condition that modern trams adopt different pavement forms such as green pavement and hardened pavement, the grooved rail can effectively isolate the pavement from the wheel rail to protect the pavement structure, and its rail lip can also serve as a guard rail The effect is to improve the reliability of tram operation. Considerin...
