Railway fastener systems, also known as rail fastener systems, are an important part of railway infrastructure, used to fix rails to sleepers, maintain track gauge and prevent longitudinal and lateral movement of rails relative to sleepers.
Washers may seem ordinary, but they play an important role. They are usually placed between bolts or nuts and fasteners to increase the force area, disperse the pressure of bolt heads or nuts, prevent local indentations and damage the surface of components. In the high-vibration environment of railways, locking washers such as spring washers can also increase friction and effectively prevent bolts from loosening due to vibration.
Pads are key components that provide buffering and support for tracks. During railway operation, the huge weight and high-frequency vibration of trains will have a strong impact on the tracks. Pads can effectively disperse these forces, reduce the wear of tracks and sleepers, and extend the service life of track structures. For example, the new mesh perforated elastic pads, with unique structural design, significantly improve the damping performance and perform well in vibration reduction.
Railway spikes are used to connect rails and sleepers or pads and sleepers. Ordinary spikes, also known as hook spikes or dog spikes, are mainly used to connect rails or pads with wooden sleepers. The tip is chisel-shaped. When nailed in, the chisel is perpendicular to the wood grain to avoid splitting the wooden sleeper. The frost damage spike has a longer spike rod and is mainly used to treat track frost damage, but its thrust resistance is relatively weak. Spiral spikes are often used to connect rails and concrete sleepers and are fixed in the reserved holes of concrete sleepers by sulfur anchoring.
Plastic dowel are often used to locate and connect parts in railway systems. It can prevent the relative position of two parts from shifting and ensure the stable operation of the equipment. Plastic materials have certain insulation and corrosion resistance, and are widely used in some railway facilities that require electrical performance and corrosion resistance.
