There are many types of railway spare parts, and fish plate is just one of them. Although the fish plate is a small spare part on the entire railway, it is also an important part of the railway line and plays an important role in the construction and maintenance of the railway.
The fish plate is provided with a screw hole in the middle. The upper and lower sides along the horizontal axis of the screw hole are provided with an upper working surface contacting the lower part of the rail head and a lower working surface contacting the upper part of the rail bottom. The rear part of the working face extends upward to form a transition section higher than the rail surface, and the transition section forms a bridge arch with a middle height and low ends along the length of the fishplate. The bridge-shaped fish plate 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.
Fishplate, also known as rail joint bar, is a connection fastener used for the connection between railway track and railway track. The main function is to fix the rail on the sleeper or rail fastening system, except that there must be a certain amount of 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, causing the train to swing large, reducing ride comfort and even affecting driving safety. The fish plate has the characteristics of following the deformation of the rail, not easy to relax, and excellent fatigue resistance.
For the normal operation of the railway line, the fish plate must be inspected and maintained as necessary. If you need to buy fishplates during the maintenance process, you can consult us.
