Measures to prevent tie plate slip derailment
Improving Friction Performance
Surface Treatment: Increase the surface roughness of the tie plate through sandblasting, embossing, or coating.
Material Optimization: Select high-hardness, high-wear-resistant steel materials.
Enhancing Bolt Fastening
Regular Inspection: Ensure that the bolt tightening force meets design requirements.
Anti-Loose Devices: Use spring washers or lock nuts to prevent loosening.
Design Optimization
Increase Contact Area: Design a larger contact surface for the tie plate to improve friction.
Upgrade Fastening Systems: Use elastic fastening systems to reduce rail creep.
Environmental Adaptability
Anti-Contamination Measures: Regularly clean contaminants from the surface of the tie plate.
Temperature Compensation: Implement additional anti-slip measures in high or low-temperature environments.
