Science populaire du collier de serrage pour rails, le “Gardien des rails” dans les trains

In the railway system where trains run, rail clamp may seem inconspicuous, but it is a key component to ensure the stability of the rails and the safe running of trains. The following will popularize it from the aspects of working principle, type and structure, function and significance.

Working Principle

The working principle of Rail Clamp is based on mechanical fixation and force transmission. After the rails are laid, the two adjacent rails need to be tightly connected to form a continuous and stable track structure. The Rail Clamp is installed at the connection between the two rails and is tightly fixed to the rails by bolts. When the train is running, the rails are subjected to huge pressure, tension and vibration. Rail Clamp can evenly distribute these external forces to the adjacent rail sections to avoid deformation, fracture or displacement of the rails due to excessive local force. En même temps, Rail Clamp can also limit the displacement of the rails in the horizontal and vertical directions, ensuring that the rails always remain in the correct position, providing a smooth and safe running track for the train.

Type and structure

Type
Ordinary rail clamp: This is the most common type, suitable for general lines, and can meet the needs of daily train operation.
Insulated rail clamp: Used in electrified railways or lines with special insulation requirements, it can prevent current from conducting between rails and ensure the normal operation of signal systems and electrical equipment.
Telescopic adjuster rail clamp: Used at the telescopic adjuster of the railway, it can adapt to the expansion and contraction of the rails due to temperature changes, ensuring the continuity and stability of the track.
Structure
Rail clamps are usually made of high-strength steel, in the shape of long strips, with slots on both sides that match the waist of the rails, which can clamp the rails tightly. There are multiple bolt holes on the rail clamp, and the rail clamp is fixed to the rail by bolts, nuts and washers. The number and specifications of the bolts will be designed according to factors such as the type of rail, train speed and load.

Function and significance

Ensure driving safety
Rail clamps can ensure that the rails are firmly connected, prevent the rails from loosening, shifting or breaking during the operation of the train, thereby avoiding serious safety accidents such as train derailment, and provide reliable protection for the safe transportation of passengers and goods.

Maintain track geometry
It helps to maintain the stability of the geometric dimensions of the rails such as straightness, horizontality and track gauge, so that the train can run on a stable track, reduce the shaking and bumping of the train, and improve the comfort of passengers.

Easy to repair and replace
When the rails are damaged or need to be replaced, the rail clamps can be easily disassembled and installed, which is convenient for railway maintenance personnel to carry out rapid repairs and repairs, reducing the impact on railway transportation.

Adapt to different line conditions
Different types of rail clamps can meet the needs of different line conditions, such as electrified railways, heavy-load railways, etc., which improves the adaptability and flexibility of the railway system.

As an important part of the railway track system, the rail clamp is not large in size, but it plays a vital role. It silently guards the safety and stability of the rails and provides a solid guarantee for the high-speed and safe operation of the train.
