Product Introduction
The SKL14 spring rail fastening system is a key connection device for fixing rails in railway track construction. It consists of high-strength alloy steel spring bars, cast iron base plates, engineering plastic insulation parts and anti-loosening bolts.
The system forms a stable and reliable mechanical connection between the rails and concrete sleepers through the unique elastic deformation characteristics of the spring bars. It can generate a continuous buckle pressure of 8-12kN under standard working conditions. The system adopts a modular design, including three functional units: gauge adjustment, insulation buffer and mechanical locking. It can effectively control the vertical and lateral displacement of the rails, while allowing the rails to produce ±5mm longitudinal expansion and contraction when the temperature changes.
The fastening device has good fatigue resistance and can still maintain more than 85% of the initial buckle pressure after 2 million cycles of load testing. Its insulation components can ensure a track circuit impedance of more than 1.5kΩ·m. It is particularly suitable for passenger and freight railways with an axle weight of less than 25 tons and a speed of less than 200 kilometers per hour. It can maintain stable working performance in the ambient temperature range of -40℃ to +60℃. Daily maintenance only requires regular inspection of the bolt torque and spring bar deformation status. It has the characteristics of convenient construction and simple maintenance.
