How Are Elastic Fasteners Specifically Classified?
There are many types of railway accessories, and different railway accessories play different roles. It is precisely because railway accessories can be divided into many types, so everyone's understanding of railway accessories is generally one-sided. Clip fasteners are a common railway accessory. In order to let everyone know about clip fasteners, we will introduce you to the specific classification of clip fasteners to help you better understand clip fasteners.
Railway rail fasteners are parts used to combine rails and sleepers (or other types of under-rail foundations) on the track, also known as intermediate joint parts. Its function is to fix the rail on the sleeper, maintain the gauge and prevent the vertical and horizontal movement of the rail relative to the sleeper.
The railway rail fastener system is divided into a shrapnel fastener system, a gusset fastener system, and a spring fastener system. The gusset type fastener is composed of a gusset plate, threaded spikes, spring washers, iron seats and buffer pads. The threaded spikes are anchored in the reserved holes of the concrete sleeper bearing platform with sulfur cement mortar, and then bolts are used to fix the gusset plate buckle up. Ellipse fasteners have elastic elements I, II, and III. Spring bar type I is composed of ω spring bar, spiral spike, gauge baffle and rubber pad. Its buckle pressure is lacking and the spring range is too small. The shape of the elastic type II is opposite to that of the elastic type I, and the elastic distance is not less than 10mm. The buckle pressure is improved compared with the elastic type I. Ellipse type III is a shoulderless fastener, which is suitable for heavy traffic and high-density transportation conditions. It has the advantages of large buckle pressure and good elasticity. Possibility of lower lateral displacement.
