Problems solved by technology

Considering that the wheel rim will move up and down on the track due to the wear of the wheel in actual use, since the special-shaped joint is in the transition area between the ordinary steel rail and the grooved rail, there will be a wheel-rail transition at the joint position. When the wheel rim moves down, The rail lip part of the grooved rail may collide with the wheel flange, so the stability and safety of train operation will be greatly reduced at the connecting part

Embodiment Construction

[0032] The specific embodiments of the present invention will be further described in detail by describing the embodiments below with reference to the accompanying drawings, so as to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

[0033] Such as Figure 1-Figure 3 As shown, the present invention provides an improved grooved rail special-shaped joint, which includes a grooved rail section 15 , a transition section 14 and an I-shaped rail connecting section 13 connected as one. The shape of the end face of the grooved track section 15 is the same as the end surface of the grooved rail to be connected, so the end of the grooved track section 15 can be easily welded to the end of the grooved rail, and has better connection strength without stress concentration. The special-shaped joint is cut and processed by the grooved rail, and the overall structure is similar ...

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...
