Fishtail plate (rail joint splint) is commonly known as splint, which plays a connecting role at the rail joint and is a common rail joint fitting. The traditional fish-tail plate is usually cast with all-steel material. Although it has the advantages of high strength and good rigidity, it has the advantages of high weight, anti-corrosion, poor insulation, and so on. When the temperature change is large, it is easy to break and so on, which makes the steel fishtail plate have some accident risk in the process of use.
The "Mechanical insulation joint" of the traditional steel fishplate and the insulating component, the mechanical insulation joint is a "insulating joint" made of steel fishplate, insulation pipe, rail end insulation and bolt. the track circuit is used for monitoring the occupation and departure of the train on the line of the section or the station through a track circuit, The track circuit is one of the indispensable safety base equipment on the railway operation line. However, due to the weak structure of the insulation part, the "Mechanical insulation joint" is easy to damage in the long-term operation, and the two seasonal decomposition and inspection shall be carried out every year, and the damaged insulation accessories shall be replaced, and the daily maintenance shall be carried out by inspection and "Sunroof" repair. In view of the defects of the existing steel fishtail plate, we have developed a composite fishtail plate, which is made of two-component polyurethane as raw material and glass fiber as reinforcing material. The product has high fiber content and high strength through pultrusion molding process. Fire retardant, high and low temperature resistance, low creep and other excellent properties. The fishtail plate made of fiber reinforced polyurethane composites can ensure the stability of track circuit.
The composite fishplate-characteristic:
composite fishplate has strong mechanical property and excellent insulating property, corrosion resistance, water resistance, anti-aging, high weather resistance, And a sectional reinforced steel guard plate is designed between the product main body and the fastener to improve the safety performance of the product. The composite fishplate product greatly improves the reliability of the insulation of the track circuit during the long-term use of the fishplate, greatly prolongs the maintenance period and greatly reduces the workload of the maintenance and replacement. The product can be used in the fields of high speed, high speed railway and urban rail transit.
