Railway Rail Compromise Fishplates

Compromise Fish Plates(Bridge-shaped Rail fish plate), with screw holes in the middle, upper and lower sides along the horizontal axis of the screw holes are provided with upper working surfaces that are in contact with the lower part of the rail head, and a lower part that is in contact with the upper part of the rail bottom. In the working face, the rear part of the upper working face extends upward to form a transition section higher than the rail surface, and the transition section forms a bridge arch shape with a middle height and low ends along the length direction of the fishplate. The bridge-shaped rail joint bar has a simple structure, which can reduce the impact of wheels on the rail joint, increase the continuity of the longitudinal deformation of the rail at the joint, and improve the smoothness of the train when passing through.
In order to ensure the overall safety of railway turnouts, it is composed of the safety of each component. Therefore, although the fishplate is small, it plays a large role in railway turnouts. For the normal operation of railway turnouts, it is necessary to inspect and maintenance on the railway rail fish plates.
Railway Rail Fishplate is also called track joint splint or rail splint. It is a connecting fastener used for connecting rails and rails. The main function is to fix the rail on the sleeper or elastic base plate, except that there must be a certain amount of force, in addition to the pressure, it must be able to withstand the vertical force, lateral force and longitudinal force from the rail. In order to avoid the three-way force from causing excessive deformation, resulting in large train swings, reducing ride comfort and even affecting driving safety, the commonly used types of fasteners are mostly composed of spring blades or elastic clips. Compared with the pressure plate, rail joint bar has the characteristics of following the deformation of the rail, not easy to relax, and superior in fatigue resistance.
