Railway fastening plates are an important part of the railway track system.
I. Functions
- Fixing rails
Railway fastening plates, in cooperation with accessories such as elastic clips and bolts, firmly fix the rails on the sleepers to prevent displacement of the rails during train operation and ensure the smoothness and safety of train travel.
- Providing elasticity
Railway fastening plates are usually made of materials with certain elasticity and can provide a certain elastic buffer when trains pass, reducing the impact force on rails and sleepers and prolonging the service life of the track.
II. Characteristics
- High strength
Due to the need to bear the huge weight and impact force of trains, railway fastening plates generally have high strength and can ensure that there will be no deformation or damage during long-term use.
- Wear resistance
Components on railway tracks are constantly subject to friction and wear. Railway fastening plates are made of wear-resistant materials or undergo special surface treatment to improve their wear resistance and ensure long-term stable performance.
- Corrosion resistance
Railway tracks are usually exposed to the natural environment and are easily eroded by rain, moisture, etc. Railway fastening plates need to have good corrosion resistance to prevent rust and damage.
III. Types
- Different material types
Cast iron fastening plates: Have relatively high strength and hardness, and the cost is relatively low, but they are heavier.
Rubber fastening plates: Have good elasticity and shock absorption performance and can reduce noise and vibration during train operation.
Composite material fastening plates: Combine the advantages of multiple materials, such as high strength, light weight, and corrosion resistance.
- Different usage scenario types
High-speed railway fastening plates: Designed for the operating characteristics of high-speed trains and have higher precision and stability.
Ordinary railway fastening plates: Applicable to railway lines with conventional speeds.
Heavy-load railway fastening plates: Can withstand the huge pressure of heavy-load trains and have higher strength and durability.
