Fish plates are also called rail joint bar, which serves as a connection at the rail joint. Many people don't know why it is called fishtail board. The fish in this term is derived from the French word â€˜ficheâ€™, meaning a peg. â€˜Ficheâ€™, in turn, is derived from the old French word â€˜fichierâ€™, which means to fasten . Thus a fish plate means a plate that fastens.
The structure of the fish plate:
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, 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.
Insulated fish plate:
The insulating fishplates are all made of insulating materials. Insulating fish plate is a new type of track material made of high-strength composite material. It is corrosion-resistant, anti-rust, anti-ultraviolet, non-conductive, and non-magnetic. It is a thermosetting material and cannot be processed twice, so it is not afraid of theft.
Insulated fish plate classification:
Insulated light rail fish plate has 8KG.9KG.12KG.15KG.18KG.22KG.24KG.30KG. Insulated heavy rail fish plate has 38KG.43KG.50KG.60KG.QU70.QU80.QU100.QU120
Fish plate classification:
The fish plate model can be divided into 8kg, 12kg, 15kg, 18kg, 22kg, 24kg, 30kg, 38kg, 43kg, 50kg, 60kg, 75kg according to the rail.
There are two types of common cast iron fishplates: four-hole fishplates and six-hole fishplates. Insulated fishplates abroad include BS47 and UIC series, such as BS80A, BS75R, UIC60, and UIC54. There are four more specifically.
According to the material, the fish plate can be divided into:
Nodular cast iron, Q235 rolling, forging, etc.
The fish plate mainly uses medium carbon steel and high carbon steel as raw materials. The fish plate models mainly produced by Kingrail Parts are 115RE, 132RE, UIC60, UIC54, BS80A, BS90A, BS100A, 90/91LB, etc. In addition, we also produce machined composite fishplates and cast iron or cast steel fishplates.
