The use of different types of railway fastener systems
Type and use
1. Shrapnel fastening system
Purpose: The shrapnel fastener system through its unique shrapnel design, the rail is firmly fixed on the rail pillow, while maintaining the stability of the gauge, to prevent the rail from moving in the process of the train. The system has the advantages of simple structure, convenient installation and relatively low cost.
Application scenario: It is suitable for various types of railway lines, especially in medium and low speed railways and urban rail transit.
2. Fastener system
Usage: The fastener system uses the fastener plate to press the rail onto the rail pillow and fix it by bolts or other fasteners. The system has high stability and load capacity, and can resist various forces and vibrations during train operation.
Application scenario: It is suitable for high-speed railway, heavy-haul railway and other occasions that require high track stability.
3. Clip fastening system
Use: The elastic deformation of the elastic bar is used to fix the rail. By adjusting the tension of the elastic bar, it can adapt to different gauge and line conditions. The system has the advantages of easy installation and adjustment, stable buckle pressure and long service life.
Application scenario: Widely used in a variety of railway lines, especially in the need to frequently adjust the gauge and line conditions.
4. Spike fastening system
Uses: Spike fasteners system mainly through the spike to fix the rail on the rail pillow, although the structure is relatively simple, but in some specific conditions still has a good fixing effect.
Application scenario: It is mainly used in some occasions where the requirement for track stability is not particularly high, or as a temporary fixing measure.
5. High strength bolt connection system
Use: In the structure of railway vehicles, such as bogies, brake cylinders, water tanks and other heavy equipment, often use high-strength bolts to connect. These bolts can withstand huge operating loads and impact forces, ensuring a solid connection of vehicle components.
Application scenario: Suitable for all railway vehicle components requiring high strength connections, especially in high-speed trains and heavy trains.
