How to install fish plate in railway

Rail joint, also known as the fish plate in railway, is a common accessory on railway tracks. As a major railway country, China uses different types of rails and different models. Therefore, for the fixed parts such as road splints, the specifications are also different. Fishplate is a common fastener on rails. In addition to testing the quality of the fishplate, it should also be installed to prevent improper installation and affect its normal use. Let’s follow the splint manufacturer to see how to install the fish plate on the railway.

1. When screwing on the bolt, pay attention to make the opening of the spring washer downward;
2. The order of the bolts, such as using a four-hole fish plate, first tighten the middle two, then the two sides, after tightening the two sides, and then tighten the middle once;
3. When screwing the bolts, one person shall use a 55cm screw wrench as the criterion, and a too long screw wrench or two people shall not be used for screwing;
4. When the bolts cannot be worn, use a hammer to hit both ends of the fishplate, align the eyes, and do not drive the screws in with a hammer;
5. The contact part between the fish plate and the rail and the bolts should be oiled;
6. When threading the fishplate bolts, the positions of the bolt caps must be staggered from inside and outside.

Through the above understanding, we also know more about the installation method of the fish plate in the railway and have a deeper understanding of the fish plate. After all, the fish plate is an accessory used on the rails.
According to the material, there are: Q235: Chemical composition (melting analysis) of plywood steel is less than or equal to 15kg/m and greater than 15kg/m by model
It should meet the requirements of Q235-A (or No. 3 B steel) and Q255-A (or No. 4 B steel) steel in GB 700 respectively.

Ductile iron: QT400-18 is placed in the field with the rails all year round. If the maintenance work of the fishplate is not done well, it will be damaged by the extrusion and friction of the train and the rail for a long time. . Therefore, the maintenance personnel should regularly repair the rails, and if the fish plate is found to be faulty, it should be replaced in time.

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...

There are six major steel mills in China producing rails with an annual output of millions of tons. G...

What are seamless rails? seamless rails Continuous seamless rails, also known as a welded long rail line, is a line that welds ordinary rails without leaving rail seams. meters or longer. The long rails are laid and fixed on the sleepers within the specified temperature range. There are rail slits at the end of the long rail, and the middle part cannot expand or contract with the temperature rise and fall. Therefore, the middle section of the steel rail will generate a large temperature pressure in summer and a large temperature tension in winter. The large pressure and tensile force in the rail can be calculated according to the annual high and low temperature of the place where the rail is laid. The large pressure on the rail should not cause the rail to buckle, and the large tensile force should not cause the rail to break. The seamless rails line greatly reduces the rail joints , reduces the impact on the rails when the wheels pass through the joints, is conducive to s...
