What are the characteristics of rail fasteners?
Oct 23, 2024| 1. In terms of mechanical properties, it exhibits high strength
Because it has to withstand the huge pressure, impact force and various dynamic forces brought by the train, such as traction, braking force and vibration, it must have sufficient strength. It is generally made of high-quality steel or alloy materials, and undergoes special heat treatment and processing technology to ensure that it will not be easily deformed or damaged in harsh working environments. At the same time, good toughness is also one of its characteristics. When subjected to impact force, it can absorb part of the energy, prevent brittle fracture, and reduce damage to the track structure.
2. In terms of fastening performance, reliable buckle pressure
It can firmly fix the rails on the sleepers or track plates to prevent the rails from shifting during train operation and ensure the stability and safety of the track. Buckle pressure is usually provided by the elastic deformation of components such as spring bars and buckle plates, and the appropriate buckle pressure range is determined according to different track types and usage requirements. In addition, stable fastening force is also the key. There is no loosening phenomenon in long-term use. Anti-loosening measures such as anti-loosening nuts and spring washers and reasonable structural design are used to improve the stability of the fastening force.
3. Corrosion resistance
Rail fasteners are exposed to the natural environment for a long time and are susceptible to erosion by rain, moisture, salt, etc., so they need to have good corrosion resistance. Corrosion-resistant materials such as stainless steel, galvanized steel, etc. can be used, or surface anti-corrosion treatment such as hot-dip galvanizing, spraying, etc. can be performed. In some special environments such as near chemical plants and coastal areas, they also need to have certain chemical corrosion resistance.
4. Convenience of installation and maintenance
Rail fasteners are easy to install, using standardized design and installation methods, which is convenient for workers to operate. For example, spring clip fasteners can be quickly installed with special tools, saving construction time and cost. At the same time, it is also easy to maintain. Reasonably designed fasteners are easy to disassemble and replace, which is convenient for repair and maintenance work, and should have a long service life, reducing maintenance frequency and cost. These characteristics jointly ensure the safe, stable and reliable operation of railway tracks.
