Problems solved by technology
However, due to the relatively weak structure of the insulating part, the "joint" is easily damaged during long-term operation. The "mechanical insulating joint" must be disassembled and inspected twice a year to replace some damaged insulating parts. Daily maintenance depends on patrol inspection and " sunroof repair

Embodiment Construction
[0026] The present invention will be described in detail below in terms of specific embodiments in conjunction with the accompanying drawings. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It is to be noted that other embodiments may be utilized or structural and functional modifications may be made to the embodiments set forth herein without departing from the scope and spirit of the invention.
[0027] Provided in the present invention such as figure 2 In the illustrated embodiment of a fishplate made of fiber reinforced polyurethane composite material, it is installed on both sides of a steel rail 205 through bolts 202 , including a main body 201 of the fishplate and a segmented steel guard plate assembly 203 . The segmented steel guard plate assembly 203 includes several separated steel guard plates, and the steel guard plates are provided with through holes corre...

The invention provides a fiber-reinforced polyurethane composite material fishplate. Fiber-reinforced polyurethane composite material fishplates are installed on the two sides of a steel rail through bolts. The fiber-reinforced polyurethane composite material fishplate is characterized by comprising a fishplate body and a sectional type steel guard plate assembly, wherein the sectional type steel guard plate assembly comprises a plurality of steel guard plates separated from one another, and through holes corresponding to fishplate body mounting holes are formed in the steel guard plates; the two fishplates are installed on the two sides of the steel rail respectively due to the fact that the bolts penetrate through the through holes and the fishplate body mounting holes; the face, close to the steel rail, of the fishplate body is correspondingly matched with a rail web of the steel rail, the bottom surface of a rail head of the steel rail and the top surface of a rail bottom of the steel rail in shape, and the other face of the fishplate body is matched with the steel guard plates; at least one hollow portion is contained in the fishplate. Insulation reliability of the fishplate relative to a rail circuit in the long-term use process is greatly improved, the examination period is greatly prolonged, and the workload of maintenance and replacement is also greatly reduced.
Description
technical field [0001] The invention relates to railway rail fittings, in particular to a fiber-reinforced polyurethane composite material fishplate. Background technique [0002] Fish plate (track joint splint), commonly known as road splint, plays a connecting role at the track joint and is a common connection accessory for railway rails. The traditional fishplate is usually made of all-steel casting. Although it has the advantages of high strength and good rigidity, its disadvantages such as heavy weight, non-corrosion resistance, poor insulation performance, and easy to break when the temperature changes greatly make the steel material Fishplates have a certain risk of accidents during use. [0003] The traditional "mechanical insulation joint" composed of steel fishplate and insulating parts, the mechanical insulation joint is an "insulation joint" composed of steel fishplate, insulation pipe, rail end insulation and bolts. On the railway line, the track circuit is us...
