Railway fastener manufacturers take you to understand the types and characteristics of elastic fasteners

Page view

The railway fastener manufacturers tell you that there are many types of clips, such as type I clips, type II clips, type III clips, etc. Different types of clips have different characteristics and can be applied to different tracks. Therefore, when purchasing, the user needs to choose the appropriate spring bar according to the model of the turnout.

Except for the redesign of the spring bar with new materials, the other parts of the spring bar type II fastener are the same as the spring bar type I fastener, which is still a shoulder and bolt fastener. The railway fastener manufacturer tells you that the original type I fastener can be replaced with the spring type II fastener in the area where the spring type I fastener was originally used. The buckle pressure of a single elastic strip is not less than 10KN, and the elastic range (that is, the elastic deformation) is not less than 10mm, which is about 30% higher than that of the I-type fasteners. After the assembled fasteners are subjected to 2 million cycles of transverse fatigue load, each part shall not be damaged. On the basis of the optimal design of the elastic strip, the diameter of the elastic strip is determined to remain unchanged, which is the same as the type I fastener, which is still 13mm. The elastic type II fastener has the advantages of high buckle pressure, large strength safety reserve, and small residual deformation.
Type III spring clips are boltless and shoulderless fasteners. Railway fastener manufacturers tell you that boltless and shoulderless fasteners are the development trend of sleeper fasteners in various countries, especially suitable for heavy-duty, large-volume and high-density transportation conditions. The spring bar type III fastener uses the cast shoulder embedded in the concrete sleeper to maintain the gauge, bear the lateral force, withhold the rail with the spring bar, and use the nylon block as the insulating part to adjust the gauge. The type III spring clip has the advantages of high buckle pressure and good elasticity. The railway fastener manufacturer tells you that the concrete sleeper shoulder is especially cancelled, thereby avoiding the possibility of the rail base moving laterally under the action of lateral force, which may lead to the expansion of the gauge. Therefore, the ability to maintain the gauge is very strong, and the maintenance workload of the fastener is reduced due to the cancellation of the bolt connection.
