What are railway accessories?
railway accessories
There are many kinds of railway accessories, we can provide railway accessories with complete varieties, reliable quality, and reasonable prices according to the needs of users. Railway accessories are an integral part of railway lines, where the track includes steel rails, sleepers, rail joints, ballast beds, anti-climbing equipment, rail brackets, and turnouts. The structure and track, as a whole project, are laid on the roadbed, play a guiding role in the operation of the train, and directly bear the huge pressure of the vehicle and its load. Under the dynamic action of train operation, each component of the train must have sufficient strength and stability to ensure the safe, stable, and uninterrupted operation of the train at the specified speed.
Railway rail fasteners
Railway rail fasteners are parts used to connect rails and sleepers, also known as intermediate connecting parts. Its function is to fix the rail on the sleeper, maintain the gauge, and prevent the rail from moving vertically and horizontally relative to the sleeper. The railway rail fastener system is divided into a shrapnel fastener system, a gusset fastener system, and an elastic strip fastener system. The buckle-type fastener is composed of a buckle plate, a screw nail, a spring washer, an iron seat, and a backing plate. The threaded spikes are anchored in the reserved holes of the concrete sleeper-bearing platform with sulfur cement mortar, and then the gusset plate is fastened with bolts. The elastic fasteners are of the elastic type. The elastic strip is composed of elastic strips, screw spikes, gauge baffles, and rubber pads.
The buckling force is insufficient and the elastic range is small. The shape of the type elastic strip is the same as that of the type elastic strip, and the elastic range is not less than 10 mm. The buckling force is higher than that of the elastic strip. The elastic band is a shoulderless fastener for bulky, high-density shipping conditions. It has the advantages of large fastening force and good elasticity, especially the concrete shoulder is eliminated, and the possibility of lateral displacement of the rail bottom under the action of lateral force is eliminated.
