fastening of rails
Elastic spacers and rail baseboards
These components are usually installed in the grooves of the sleeper and serve to support and secure the rail.
Bolts and nuts
The bolts are installed on both sides of the rail and pass through the holes of the reinforced concrete sleeper, while the nuts are pressed against the upper surface at the bottom of the rail, along with the elastic elements and pressure devices.
Pressure devices
such as wedge pressure devices, apply pressure through the eye shaped head of the bolt, whose arched surface matches the shape of the wedge surface, thus enhancing the tightening effect.
Fastening method and characteristics
Elastic fastening
Use elastic elements (such as U-clips) to clamp the bottom of the rail and provide additional pressure through fastening devices (such as bolts and nuts) to keep the rail stable. This fastening method can accommodate the small deformation of the track due to temperature changes or train passing.
Rigid fastening
Compared with elastic fastening, rigid fastening parts and connections are more robust, suitable for applications that require higher stability and accuracy. However, it may not be as flexible to accommodate small deformations of the rail as elastic fastening.
Advantages
Reliability
The reliability of fastening components and structures is essential for railway operation. If the fastening is not strong or the parts are damaged, it may cause the rail to loose or shift, which will affect the safe operation of the train.
Service life
The durability and service life of the fastening parts are also important indicators to evaluate the fastening effect. High quality fastening parts and proper fastening methods can extend service life and reduce maintenance and replacement costs.
Anti-crawling characteristics
In the case of a train running for a long time or subjected to a large lateral force, the rail may produce crawling phenomenon (that is, the rail moves slightly in the longitudinal direction). A good fastening method should be able to effectively prevent or limit the occurrence of this crawling phenomenon.
