Description

Technical Field

[0001] The utility model relates to the technical field of rail clamps, and more specifically to a high-strength rail clamp. Background Art

[0002] The rail clamp is also called a welded rail clamp, a welded rail fixing device, a steel beam rail clamp, and a welded pressure plate. Its function is to clamp and fix the rails. Since the upper cover pressure plate of the rail clamp needs to withstand the huge force generated by the passing of the train, it is often made of ductile iron or cast steel. It has the advantages of high strength and good compressive resistance. However, in actual use, due to the passing of a vehicle above the track, the vibration force is relatively large, which can easily damage the pressure plate.
