A single switch is a common piece of railway equipment that is mainly used to change tracks from one direction to another. It consists of two parallel rails forming a passage through which vehicles can enter the line.
Structural: The switch of the equipment has only a pair of parts such as a rut fork and a back guard;The guiding mode is mainly dominated by straight strands, and the non-dominant wheels run on the outside of the curve on one side and can achieve the purpose of reliable shunting. The relationship between its part and the basic rail is similar to the relationship between an acute angle and its hypotenuse in a right triangle, so that the optimal amount of locking can be determined to meet different needs (i.e., high accuracy) by adjusting the relevant parameters. In addition, the length of the straight line and the height of the outer rail on the curve can be designed according to the actual needs to meet the needs of specific application scenarios. The material is mainly 60SIMNA alloy tool steel, and the surface hardness can reach HRC58-62 after heat treatmentThe abrasion resistance is quite goodThere are advantages in size, especially in small numbers and U-shaped (symmetrical) turnouts, which can reflect the advantages of the future: such as good climbing performance, strong stability, etc., which are determined by its special structural design. Functional use: The single turnout has the characteristics of simple and compact structure and easy maintenance, which can not only flexibly set various train bogie types according to user needs, but also can be combined with different models to form the required form of tractor bottom (referred to as combined general splint).This greatly reduces the maintenance operation content of the public works section and greatly improves the efficiency at the same time, bringing economic and social benefits to the operating unitTo sum up, the "two-column rotating wing" + "ZD(J)-97 series single turnout" can effectively solve the on-site construction problems of the existing line speed-up.
It should be noted that in the process of use, the lubrication status of each rotating part should be checked regularly, and the mouth should not be knocked in the parking state, so as not to damage the parts and affect the use effect. This is an introductory text description paragraph about the traffic control equipment and manufacturing technology used on a common high-speed railway, I hope you find it helpful!
