types of fishplates

The fish plate is commonly known as the rail joint bar, which plays a connecting role at the track joint. Divided into light rail, heavy rail, and crane rails. The fishplate is a connecting fastener used for the connection between the track and the track. Compared with the rail butt welding technology, the use of the fishplate saves time and labor, and the installation is simple and quick. The fishplate is used in conjunction with the fishtail bolt. The fish plate is provided with screw holes in the middle, and the upper and lower sides along the horizontal axis of the screw holes are provided with an upper working surface in contact with the lower part of the railhead, and a lower working surface in contact with the upper part of the rail bottom. The rear 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 high middle, and low ends along the length of the fishplate. Most types of fishplate have a simple structure, that can reduce the impact of the wheel on the rail joint, increase the continuity of the longitudinal deformation of the rail at the joint, and improve the smoothness of the train passing through.

  1. The types of fishplates are 8kg, 9kg, 12kg, 15kg, 18kg, 22kg, 24kg, 30kg, 38kg, 43kg, 50kg, 60kg, 75kg according to the rail.
  2. There are two kinds of ordinary cast iron fishplates: four-hole fishplate and six-hole fishplate, and there are BS47 and UIC series of insulating fishplates abroad, such as BS80A, BS75R, UIC60, and UIC54. Specifically, there are four kinds.

What are railway rail fasteners？

What are railway rail fasteners？ Railway rail fasteners Railway rail fasteners are a kind of railway accessories. The parts used to combine rails and sleepers (or other types of under-rail foundations) on the track are also called central joint parts. Its function is to fix the steel rail on the sleeper, maintain the gauge and prevent the longitudinal and lateral movement of the rail relative to the sleeper. The railway rail fastener system is divided into the shrapnel fastener system, gusset fastener system, and elastic strip fastener system. The gusset-type fastener is composed of a gusset plate, a threaded spike, a spring washer, an iron seat, and a buffer pad. The threaded spike is anchored in the reserved hole of the concrete sleeper bearing platform with sulfur cement mortar, and then bolts are used to fasten the buckle. Plate fastened. There are elastic strips I, II, and III types of clip fasteners. Type I elastic strip is composed of ω elastic strip,  screw spike , gauge b...
