The maintenance and maintenance of track fasteners is an important link to ensure the safe and stable operation of the railway system. The following are some detailed maintenance and maintenance suggestions:

1. Check and tighten regularly

track fasteners need to be checked regularly for their condition, including for loosening, wear or corrosion. The loosening of fasteners may lead to the instability of the track structure, which in turn affects the safety of train operation. For example, newly installed rails should be inspected for bolts at least once a week for the first month, after which they can be inspected monthly. In addition, for areas with large vibrations, it is recommended to use lock nuts or vibration resistant rivets.

2. Lubrication and anti-corrosion treatment

For moving parts, appropriate lubricant should be applied regularly to reduce friction and wear. At the same time, for fasteners exposed to harsh environments, anti-corrosion measures should be taken, such as coating protective coatings.

3. Replace the aging or damaged fasteners

Over time, fasteners may fail due to wear, corrosion, or other reasons. Timely replacement of damaged fasteners is a key measure to ensure track safety. For example, in the maintenance of bridge rail ties, fastener replacement intervals are specified and daily concerns are emphasized.

4. Maintenance adapted to environmental conditions

In hot or cold environments, the condition of the track fasteners may be affected. For example, when the temperature is below -10°C, the rubber pad on the tie can be removed to replace the fastener. In addition, it should be ensured that fasteners can maintain performance under high temperature conditions.

5. Combined with the overall maintenance of the track

Fastener maintenance should be combined with the overall maintenance of the track. For example, immediately after a tamping operation, rigid fixtures that may become loose should be tightened and the gauge and level checked.

6. Select the appropriate fastener material and design

The material and design of a fastener are critical to its performance. High quality fasteners can be used in harsh environments for a long time without failure, thereby reducing maintenance costs and improving reliability.

7. Professional training and standard operation

Professional training for operators to understand the correct installation and maintenance methods of fasteners is an important measure to ensure the normal operation of the rail system.

8. Preventive maintenance program

Develop a preventive maintenance schedule that includes steps such as regular inspections, cleaning, lubrication, and fastener replacement. For example, the railway department recommends a comprehensive inspection of the tracks every two years and adjusting the frequency of maintenance according to the traffic load.

9. Additional measures under special circumstances

In special environments (such as lifting molten metal or in dangerous areas), the maintenance period should be shortened. In addition, the replenishment work is completed before the rainy season to prevent water damage.

10. Technological upgrading and innovation

With the development of technology, new fasteners are designed to be lighter, stronger and more durable. Using these innovative designs can further improve the stability and safety of the rail system.

The maintenance and maintenance of track fasteners need to develop a reasonable maintenance plan based on factors such as actual use environment, traffic load and seasonal changes. Through regular inspection, timely replacement of damaged parts, reasonable selection of materials and design and professional training and other measures, the service life of fasteners can be effectively extended to ensure the safe operation of the railway system.
