Common Types And Differences Of Elastic Fasteners

The clips we often refer to include Type I clips and Type II clips. What's the difference between these two snap fasteners?
Type I Railway Elastic Band: Also called a fastener. The track is fixed with elastic strips, which need to maintain a certain fixed pressure and sufficient strength. For the 50kg/m track, there are two types of track baffles, intermediate baffles and joint baffles. Each type is divided into 14 and 20 numbers, except for the B-type clips for the 14 joint baffles, the rest are equipped with A-type clips. There is only one gauge baffle for 60 kg/m rails, which are divided into No. 6 and No. 10, and uniform B-type railway spring rods are installed. The I-type elastic fastener has good elasticity, low pressure loss, and can well maintain the geometric position of the track. It has become the main fastener of the concrete sleeper production line in our country.
Type II rail spring clips: Except for the rail spring clips redesigned with new materials, other parts are used with type rail spring clip fasteners, which are still used with shoulder bolt fasteners. Elastic steel is used as the material of the type railway elastic belt, its yield strength and tensile strength are respectively 42% and 36% higher than that of the type railway elastic belt, and the diameter of the elastic belt remains unchanged. This type of fastener has the advantages of large amount of fastening, large strength and safety reserve, and small residual deformation. It is suitable for 60kg/m railway and type or type concrete sleepers. The elastic strip is an important part of the 60kg/m rail type fastener. It is mainly used Lay 60kg/m railway on straight lines and curves with standard gauge railway radius R300m. Its operating conditions are: the annual gross weight of the locomotive is 60Mt.km/km, 100Mt.km/km; the axle load is not more than 250 kN; The initial buckling pressure is not greater than 10.0kN; the elastic range is 10 mm.
