The relationship between the rail pressure plate and the rail fastener
Sep 04, 2022| Gauge Baffle
Rail fastener is a generic name, which includes spring bars, baffles, and gussets. The function is to fix the rail, the rail pressure plate is also called the track pressure plate, and the function is also to fix the rail including the rail pressure device. Although the names and shapes are different, the functions and purposes are the same. The rail clamps and rail clamps are mainly used for short-distance tracks such as driving or workshops. The rail fasteners are generally used on the line, and the use environment is different. The rail pressure plate should also belong to the series of rail fasteners.

The rail fasteners are described in detail below. The choice of fastener type should match the type of sleeper, rail and rubber pad under the rail. The specification and quantity of fasteners should be selected according to the model of the track. Laying a 60kg/m rail track, the concrete sleeper fastener clips use type II fasteners and clip type III fasteners, and the type I clips will be gradually replaced by type II clips. In the section where 50 kg/m rails are laid, the concrete sleeper fasteners are made of elastic strip I type fasteners; and the 70 type rail buckle plate type fasteners will be replaced with elastic strip fasteners. Shrapnel clamps are no longer adopted and phased out.

In order to meet the requirements of large height adjustment for local lines, type I height adjustment fasteners can be used. In order to meet the design requirements of the seamless line on the bridge, the small resistance fastener is used on the long bridge. In order to improve the anti-rust performance of fasteners, the relevant standards are revised, and the requirements for the anti-rust performance of metal parts of fasteners are added, and the anti-rust performance indicators are similar to those of high-speed railway fasteners. In order to improve the technical performance and service life of the rubber backing plate, the revised fastener standard increases the fatigue performance test requirements for the rubber backing plate.
