The fishplate (the rail joint splint) is commonly known as the road splint, which is connected at the junction of the track.It is divided into light rail, heavy rail and heavy rail.Fishplate is a kind of used to track and rail connection using the connection between the fasteners, the use of fish plate butt welding technology to save work easier than rail, simple and easy to install, fish plate with fish bolts.Fish plate, which is equipped with the screw hole, along the horizontal axis of the screw holes on both sides of the upper and lower sets and rail head lower contact on the working face, and the lower face of the upper and rail bottom contact, described on the face at the back of the upward along the stretch forming a higher than on the surface of the rail transition section, the transition section along the fishplate length direction to form high, middle low on both ends of the bridge arch.The structure of the above bridge fishplate is simple, which can reduce the impact of the wheel on the rail joint, and increase the continuity of the longitudinal deformation of the rail rail, and improve the smoothness of the train.
Type of Fishplate
1. The light rail fishplate is also known as the plywood, and the heavy rail fishplate is also known as a lifting rail splice splint. The insulating fishplate is made of insulating materials. The insulating fishplate is a new type of track material made of high strength composite material. It is corrosion resistant, anti-rust, ultraviolet ray, non - conductive, non - magnetic.It belongs to thermosetting material and cannot be processed twice, so it is not afraid to steal.
2. The fishplate model can be divided into 8kg, 9kg, 12kg, 15kg, 18kg, 22kg, 24kg, 30kg, 38kg, 43kg, 50kg, 60kg and 75kg. Light rail insulation fishplate 8 kg. 9 kg. 12 kg. 15 kg. 18 kg. 22 kg. 24 kg. 30 kg. Light rail fishplate aka plywood, insulation insulation heavy rail fishplate 38 kg. 43 kg. 50 kg. 60 kg. QU70. QU80. QU100. QU120 aka crane rail oblique joint plywood.
3. Normal cast iron fishplate has four holes of fishplate and six holes of fishplate, and the insulated fishplate has BS47 and UIC series abroad, such as BS80A, BS75R, UIC60 and UIC54. There are four more.
4. The fishplate is divided according to the material: nodular cast iron, rolling, forging etc. Fishplate main use of medium carbon steel and high carbon steel as raw material, we main produce the fishplate models for 8 kg, 9 kg, 12 kg, 15 kg, 18 kg, 22 kg, 24 kg, 30 kg, 38 kg, 43 kg, 50 kg, 60 kg, 75 kg, S49, 115 re re, re 119, 115, 133 re, re 136, 136 re, BS75R, BS80A, BS90A, BS95RBH, BS100A, BS113A, UIC54, J75 UIC60, insulation, insulation J60, 43, QU70, QU80 J50 insulation insulation, QU100, QU120, all kinds of insulated fishplate, etc. In addition, it also produces machining composite fishplate and cast iron, cast steel, forging press, rolling, injection molding fishplate.
