Safety measures for spring fasteners of rail fastening system
First, use of high strength, high quality materials
High-strength bolts: The use of high-strength bolts as connectors can ensure that the fastener is not easy to loose or damage when it is subjected to the huge impact force brought by the train.
High quality spring materials: Select spring materials with high elasticity and corrosion resistance, which can extend the service life of the fastener, while ensuring that it can maintain good working condition under various environmental conditions.
Second, increase the pre-loading force and anti-loosening measures
Appropriately increase the preloading force: When installing fasteners, by appropriately increasing the preloading force of bolts, the friction between bolts and nuts can be increased, thereby improving the fasteners' tightness and reducing the possibility of loosening. However, it should be noted that the pre-tightening force should not be too large, otherwise it may lead to bolt breakage or fastener deformation.
Installing anti-lock gaskets: Installing anti-lock gaskets between bolts and nuts can increase the coefficient of friction and reduce relative motion, thereby improving the stability of fasteners.
Apply thread locking adhesive: Thread locking adhesive can fill the gap between the bolt and nut, increase the adhesive force between them, and prevent the fastener from loosening. At the same time, the thread locking adhesive also has the function of anti-rust and anti-corrosion, which can extend the service life of the fastener.
Third, regular maintenance and inspection
Regularly check the status of fasteners: check the spring fasteners of the track fastening system regularly, including checking the fastening state, whether there is damage or deformation of the fasteners.
Timely replacement of damaged fasteners: Once the fasteners are found to be damaged or deformed, they should be replaced immediately to ensure the stability and safety of the track.
Cleaning and lubrication: Regular cleaning and lubrication of the fastener can reduce friction and corrosion and extend the service life of the fastener.
