What are the advantages of the rail clip of the elastic strip fastener?

The bending deformation properties of the material are mainly used in the operation of the rail pressing plate of the shrapnel clip, the processing is relatively simple, and the cost is often low, but due to the opening of the hole for bolt tightening, the stress concentration is easy to occur in this part, and the surface bending moment is exactly the same. Section weakens. The arched shrapnel fasteners developed in my country in the early stage were found to be easily broken when the bolts were tightened, and the oscillations that occurred during the passing period of the train easily loosened the shrapnel track pressure plate, and even some nuts were withdrawn from the bolts. Other gauge baffles are easy to climb to the bottom of the rail under the action of oscillation, resulting in the expansion of the gauge. Track pressure plate

Track pressure plate

Except for DTⅠ and DTⅡ fasteners on subway lines, shrapnel-type fasteners are no longer used on other track lines. The bending deformation properties of the material and the torsional deformation properties of the material (especially the circular section spring bars) are used in the operation of the clip clip, so the elasticity is generally good, and there is basically no weakening of the section, so the utilization rate of the material is high. , On conventional lines, it is generally expected that the clip has a high clipping pressure and good elasticity, and the clip clip has obvious advantages in this regard.

At present, the main methods of rail clips in my country are the bolt-mounted ω-structured clips, such as type I, type II clips, Shilongqiao small resistance clips, J-2 clips, etc.; In addition, there are other types of clips, double-toe clip rails, and center clips. Spring clips are only our company's main products. Our company mainly supplies other types of railway accessories and railway components.
