Product Introduction
The railway fastener system with SKL spring clips is an elastic rail connection device with spring clips as the core fastening parts. It is widely used in railway trunk lines, urban rail transit and special engineering scenarios. Its component system achieves reliable connection between rails and sleepers through precise design, while taking into account elastic buffering, insulation protection and precise adjustment functions.
SKL Type Railroad Fasteners System Collaborative Working Principle
Load transfer path:
Train load → rail → rail pad → iron pad → elastic pad → sleeper → ballast bed, through multi-level elastic elements step by step buffering, reducing impact stress.
Dynamic balance mechanism:
The buckle pressure of the spring clip forms a dynamic balance with the stiffness of the rail pad: when the train passes, the elastic pad is compressed to increase the deformation of the spring clip, and the buckle pressure is automatically compensated; after the train leaves, the spring clip returns to its original state to maintain the stability of the track gauge.
Insulation and protection system:
The insulating gasket, casing and rail pad form a triple insulation barrier to ensure the reliability of track circuit signal transmission;
W Type Fasteners System Performance Advantages
Elastic buffering and shock absorption: The elastic pad under the rail works with the SKL spring bar to absorb more than 70% of the impact energy of the train operation, reduce the vibration acceleration of the sleeper by 30%, and reduce the bumps of the car body caused by rigid impact.
Precise geometry control: Through the gauge baffle, rail pad and height adjustment pad, high-precision adjustment of the gauge and level is achieved, and the gauge deviation of the high-speed railway is controlled within a very small range to avoid shaking caused by abnormal wheel movement.
Dynamic pressure compensation: The spring clip automatically adjusts the buckling pressure as the rail is deformed by force, strengthens the rail constraint when the wheel is rolling, and restores the rated value after leaving, maintaining the stability of the wheel-rail contact force.
Wear-resistant, damage-resistant and durable: The key components are specially treated with low wear rate, and the track geometry is maintained for a long time to avoid the change of track parameters due to component loss affecting the stability.
Elastic rail fastening plates with SKL rail clamps Fastener System Components
Ripped baseplates, "Skl" tension clamps, rail pads and under baseplate pads are used to fasten turnout parts on concrete bearers. The tension clamps ensure a permanently elastic clamping. The creep resistance and twisting resistance achieved meet the requirements placed on a continuously welded track. The baseplates are mounted on the concrete bearers by four coach screws.
Advantages of Elastic Rail Fastening System SKL Installation
Modular design, fast assembly: The components of the system (such as SKL spring bars, gauge baffles, insulating gaskets, etc.) are highly standardized and can be quickly assembled like "building blocks".
No special tool dependence: The main installation tools are conventional wrenches, sockets, etc., and no special precision equipment is required.
Adaptation to mechanical construction: The system structure is compact and stable, suitable for automated operation of track construction machinery.
