Problems solved by technology
Due to the impact force of the train on the switch rail, the tip of the switch rail is easy to wear and damage, which directly affects the service life of the switch rail and the safety of driving
In addition, when the point rail is docked with the basic rail, the tip part is also prone to friction and collision with the basic rail, which will affect its service life

Embodiment Construction
[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.
[0015] Such as figure 1 with figure 2 As shown, the present invention provides a switch rail. The switch rail 2 includes a tip part 3 and a body part, and the tip part 3 and the body part 4 are connected as a whole. One side of the tip portion 3 of the tongue rail has a chamfered surface. The sliced surface is in contact with the basic rail 1 and is used to help the train transition from the basic rail 1 to the tip rail. Described planing surface is provided with some cushioning parts 5, and some buffering parts are distributed along the length direction of described tip part, and extend from the head of described tip part to the root of described tip part, and some buffering parts The height gradually increases because the head of the tip part is closer to the basic ra...

The invention discloses a point rail which comprises a point part and a body part. A planing face is arranged on one side face of the point part, and provided with a plurality of buffer components, the buffer components are distributed in the length direction of the point part and extend from the head of the point part to the root of the point part, the height of the buffer components is increased gradually, each buffer component comprises a rod-shaped component body and a barrel-shaped component body, the lower half parts of the rod-shaped component bodies are arranged in the barrel-shaped component bodies, the upper half parts of the rod-shaped component bodies stretch out of the upper portions of the barrel-shaped component bodies, the lower end of each rod-shaped component body is connected to one end of a spring, the other ends of the springs are connected to the bottoms of the barrel-shaped component bodies, first rubber mats are fixed to the upper ends of the rod-shaped component bodies, and the barrel-shaped component bodies are fixed to the planing face. The buffer components are arranged on the point part, impacts and friction are offset through the buffer components, and abrasion to the point part is reduced.
Description
technical field [0001] The invention relates to a turnout rail piece, in particular to a switch rail. Background technique [0002] For ordinary single turnouts, it consists of a point switch, a frog, a guard rail, a connecting part and a switch sleeper, and the point switch includes two point rails, two basic rails, connecting parts and switch machinery, etc. . The switch rail is an important part of the point switch, relying on the switching of the switch rail to guide the train into the direction of the main line or the side line. Due to the impact force of the train on the switch rail, the tip of the switch rail is easy to wear and damage, which directly affects the service life of the switch rail and the safety of driving. In addition, when the tip rail is docked with the basic rail, friction and impact between the tip part and the basic rail are likely to occur, thereby affecting its service life. Contents of the invention [0003] The object of the present invent...
