Welche Arten von Eisenpolstern werden für Eisenbahnbefestigungen verwendet??

The iron base plates in railway fasteners are important components of the railway track system. They are responsible for supporting the rails, distributing the track load, and ensuring the stability and safety of the track system.

The types and models of railway fastener iron base plates are diverse to meet the needs of different railway lines.

1. Ordinary fasteners and iron base plates:

This combination is commonly used in wooden sleeper tracks and is the traditional fastening method. It mainly fixes the iron base plates to the wooden sleepers through fasteners.

2. Concrete sleeper fasteners:

There are various types, such as plate-type, arched-plate type, and spring-type. Darunter, spring-type fasteners are the most commonly used. Specific models include spring type I, e-type, ω-type, and w-type. These fasteners consist of threaded fasteners, nuts, flat washers, Federn, gauge plates, guard plates, and rubber pads etc.

3.There are two main applications:

3.1 For high-speed railways: High-speed railways have extremely high requirements for the stability and smoothness of the track. daher, they often adopt high-performance fastener systems such as WJ-7 and WJ-8. These fasteners are specifically designed for high-speed railways and have higher strength, Haltbarkeit, excellent insulation performance, and noise reduction and vibration-damping capabilities.

3.2 For urban rail transit: Metro and other urban rail transit systems have high environmental protection requirements for vibration and noise reduction. daher, the steel rail fasteners must have good vibration reduction performance to attenuate track vibrations and reduce noise transmission, Verbesserung des Fahrgastkomforts.

4.Main features of railway fastener iron base plates:

Hohe Festigkeit und Haltbarkeit: Due to the long operating time, high traffic density, and poor maintenance conditions of railway operations, the fasteners and iron base plates must have sufficient strength and durability to ensure safe operation.

4.1.Good insulation performance: In railway systems, the running rails are often used as return rails. The fasteners must have good insulation performance to prevent current leakage through the fasteners, which could cause corrosion of structural steel bars and municipal pipelines.

4.2.Excellent vibration reduction and noise reduction performance: The fasteners and iron base plates use elastic elements (such as rubber pads) to buffer the vibration impact between the wheels and the rails, reducing noise transmission and improving passenger comfort.

4.3.Easy adjustment and maintenance: Modern railway fastener systems usually have track gauge and level adjustment capabilities, which are convenient for solving problems such as wear of curved rails and uneven settlement of the structure. Gleichzeitig, the fastener structure should be simple, with few components, and easy for construction and maintenance.

4.4.General interchangeability: To improve construction and maintenance efficiency, the fastener system should have certain general interchangeability, das heißt, different models and specifications of fasteners and iron base plates can be interchanged for use.

Abschließend, railway fastener iron base plates, as key components of the railway track system, their types, models, Anwendungsszenarien, and characteristics all play a crucial role in the safety, Stabilität, and efficient operation of railways. With the continuous development of railway transportation technology, the technical level of railway fastener iron base plates will also continue to improve to better meet the needs of modern railway transportation.
