Classification and introduction of elastic fasteners

As an important part of the railway system, the spring fastener is mainly used to buckle and fix the rail on the sleeper or track slab, maintain the gauge and prevent the vertical and horizontal movement of the rail, transfer the vehicle load to the substructure, and provide a certain degree of elasticity. and deformation coordination.

In general, the elastic fastener system of the railway is composed of elastic strips, backing plates, anchor bolts, spring washers, elastic backing plates and other components. Among them, the elastic strip is the key component of the fastener system that provides elastic fastening pressure for the fastener system.

According to the fixing method of the clip, it is divided into a clip with a bolt and a clip without a bolt. The bolt clip is fixed on the iron seat by the bolt passing through the clip, while the boltless clip is through a special design, insert the clip into the socket on the iron seat, and provide pressure through its elastic deformation to fix it on the iron seat superior. Compared with the bolted clip fastener system, the bolt-free clip fastener system has a relatively simple structure and is convenient for installation and maintenance.
