2021-06-11

Fish Plate is a kind of railway accessories,also known as rail joint splint or plywood,it is a kind of used to track and rail connection using the connection between the fasteners,main effect is fixed on the sleeper rail or play a substrate,besides must have a certain pressure,must also be able to bear from the rail vertical force,the action of horizontal force and vertical force.

Compared with the track press plate,the fish plate has the characteristics of following the deformation of the rail,not easy to relax and better fatigue resistance.The fish plate can effectively reduce the impact of the vehicle on the rail joint,and can also increase the continuity of the longitudinal deformation of the rail,and can improve the ride comfort of the train from different aspects.

There is no screw hole in the middle of it.No matter how good the performance of the fish plate,the use of a long time,there will be cracks.We can do,is to do a good job of daily protection,reduce the probability of crack,can by reducing the friction coefficient,such as surface treatment,improve the quality of the surface,or in the material contact surface to join some form of intermediary.In order to ensure the overall safety of railway turnout,it is composed of the safety of each component part,therefore,although it is small,the role of railway turnout is not small.For the normal operation of railway turnout,necessary inspection and maintenance should be carried out.
