fish plate and fish bolt are connection fasteners mainly used to connect tracks. However, after a long time of use, we will find that the fish plate and fish bolt will fail. There are many reasons why fish plates and fish bolts fail, some are related to their own service life, some are related to the weather. The crack formation of fish plate and fish bolt is closely related to the interaction between fish plate and fish bolt and the rail surface. Under actual working conditions, the connection of the fish plate and fish bolt with the railway connection bolt is not strictly integral. There is a gap between the influence of the wheel and the railway, especially the tension between the railway and the fish plate and fish bolt due to wear can cause the surface deformation between the fish plate and fish bolt and the railway, or between the two, and the surface deformation between the two. The deformed fish board provides a good opportunity. Next, railway parts manufacturers will introduce you to the reasons for the installation and failure of fish plate and fish bolt.

In general, railway fish plates and fish bolts are thermosetting materials, corrosion resistant, rust resistant, UV resistant, non-conductive and non-magnetic. When using fish plate and fish bolt, compared with rail welding technology, the installation is simple and quick, and the use of fish plate and fish bolt and fish tail bolt is provided with a screw hole in the middle of the fish plate and fish bolt. Along the horizontal axis of the screw hole, the lower two sides are provided with an upper working surface in contact with the lower half of the guide rail head and a lower working surface in contact with the upper half of the bottom of the guide rail.

When installing the fish plate and fish bolt, the fish plate and fish bolt should be firmly fixed on the inside of the guide rail, and the guide bolt should pass through. Butter the fish plate and fish bolt, add it to the washing machine, and tighten the nut. The nuts on the insulated fish plate and fish bolt should be tightened against each other on both sides of the railing. The two nuts in the middle of the four-hole fish plate and fish bolt are installed inside the guide rail, and the two nuts at both ends are installed outside the guide rail.
