Do You Understand The Fishplate Of Railway Equipment?

Railway equipment fishplate is a fastener used to connect and fix rails. Its use 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 kinds of 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. When using this kind of railway equipment, different parameters of different types of tracks at both ends should be considered. 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.
Needless to say, the function of the fishplate is to fix the rail on the sleeper or the base plate of the elastic part. The fishplate is used to connect and clamp two rails to resist the shear force of the joint and prevent the rail head from misaligning. At the same time, special attention should be paid to the operation. Whether the installation of the fishplate is correct or not will directly affect the use of the track, so we must be careful and operate according to the specifications.
Here I would like to remind everyone that before installing the fishplate, the power supply of the electrical appliance under test and the circuit should be cut off, and the relevant components should be temporarily grounded and discharged. By installing and applying the fishplate, the impact of the wheel on the rail joint can be reduced, the continuity of the longitudinal deformation of the rail at the joint can be increased, and the smoothness of the train passing through can be improved.
