What are the requirements for the performance of the spring clip
2021-06-24
Because the elastic Clip of railway fastener is a relatively important railway accessory,we have certain requirements for it,so as to ensure the use effect in the future.The elastic clip works under alternating stress repeatedly,and it bears bending,torsion,fatigue,corrosion and other effects.When the vehicle passes,it also bears high instantaneous impact load,so the performance requirements of the elastic clip are very strict.Let's understand the specific requirements together. Elastic fasteners,withhold article mainly play by play of the bent and twisted,buckle pressure effect on the orbit,effectively guarantee the reliable connection between rail for a long time,as far as possible to keep the integrity of the orbit and stop the rail lateral movement relative to the sleeper,ensure the normal track,to ensure the safety of the rail vehicle.In addition,due to the contact between the train wheel and the rail is rigid contact,vibration is inevitable,and the elastic structure of the bullet bar also has the function of absorbing the impact energy generated when the vehicle passes by,and achieving the function of shock absorption. 1)Enough buckle pressure. 2)Technical disclosure before construction of concrete works in winter. 3)Raw material inspection and retest and mix ratio. The Spring Clip is mainly used to buckle the rail.It is required to maintain a certain buckle pressure and sufficient strength.0
