What Should I Do If The Fishplate Cracks?

Fishplate, as a fastener used to connect and fix rails, is less troublesome and labor-saving than rail butt welding, and its installation is simple and quick. Usually used on railway tracks or industrial and mining tracks, guide rails should be connected with fishplates during laying and maintenance. Generally, fishplates can be divided into two categories: railway and mine. The difference between these two railway fishplates is mainly based on different track parameters. This is mainly due to the influence of the space and length of the mine track, which makes the mine track narrower and the track type smaller.
Ordinary fishplate is the combined product of mine track and railway track. This kind of railway fittings is called track-changing fishplate in the application process. When using this kind of railway equipment, the different types of tracks at both ends should be considered same parameters. In addition, in addition to the corresponding pressure, it also needs to be able to bear the vertical force, lateral force and longitudinal force from the rail. Compared with the rail pressure plate, it has the characteristics of following the deformation of the rail, not easy to relax and fatigue resistance. . As one of the important railway equipment, the track fishplate is very troublesome once it cracks, so what should be done?
It is suggested that the occurrence of cracks in the fish plate can be reduced by reducing the friction coefficient. On the one hand, the cracks in the fish plate can be reduced by reducing the slip amplitude, that is, the magnitude of the relative interaction between the rail and the fish plate can be reduced. At the same time, the sliding amplitude can also be reduced according to the adjustment of the fastening force between the rail and the fishplate, and the impact can be reduced to reduce the sliding amplitude according to the condition of the improved joint. In addition, the cracks of the fishplate can also be reduced by reducing the contact pressure. There are many factors that affect the contact pressure. Reducing the contact pressure will reduce the strength of the interaction force between the rail and the fishplate.
