Railway fastener factory talks about fishtail bolts

Everyone knows that there are many types of railway fasteners, and each fastener is indispensable. Only these rail fasteners together can ensure the safety of railway operation. Just like high fishtail bolts is a very important railway fastener. Everyone knows more about railway fasteners, let's introduce the knowledge of fishtail bolts below.

Fish tail bolts and railway fishplates (rail joint bar) are connected at the rail joint. Steel rails are divided into light rail, heavy rail and overweight rail. Rail fish plates are a kind of connection fasteners used for the connection between the rail and the rail. The use of rail fishplates is more labor-saving than the steel rail butt welding technology, and the installation is simple and quick. Fish tail bolts are used in conjunction with railway fish plates. The middle part of the railway fish plate is provided with a screw hole. 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 surface 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 rail fishplate has a simple structure and can reduce the impact of wheels on the steel rail joint. The fishtail bolt increases the continuity of longitudinal deformation of the steel rail at the joint and improves the smoothness of the train when passing through.

The above is the introduction of fishtail bolts. I hope that the above introduction can help you. Only by understanding the functions of these railway fastners can you better apply them in your future work.
