Product Introduction
As a stable connection component for railway tracks, the KPO guide clamp fastening system is divided into KPO3, KPO6 and KPO9 models according to specifications. The system consists of KPO type clips, embedded sleeper screws, HS high-strength bolt pairs, disc springs and composite iron pads. The clips are made of Q235 steel, and key parts such as screws are made of 35CrMo alloy steel.
It is suitable for track fixing in mountainous railways and can resist track displacement caused by complex terrain. Its advantage lies in high shear resistance. The production process includes die forging, CNC milling, quenching and tempering heat treatment and hot-dip galvanizing anti-corrosion treatment.
KPO rail clamp is a key railway part in the KPO type railway fastener system.
Function
Fix the rail: By pressing the rail tightly against the sleeper, the rail is prevented from lateral and longitudinal displacement under the action of various forces generated by the train operation, ensuring the accuracy of the rail position, maintaining the stability of the gauge, and ensuring the safe and smooth operation of the train.
Transfer load: It can evenly transfer the train load borne by the rail to the sleeper and the lower foundation structure, reduce the local stress concentration of the rail and sleeper, and extend the service life of various track components.
Structural features
Buckle plate design: It is usually made of high-strength metal materials. The shape and size of the gusset plate are designed according to different rail types and usage requirements. Its inner side is closely fitted with the side of the rail, and it is connected to the sleeper or pad through bolts and other connectors to provide reliable buckling pressure.
Connecting parts: including bolts, nuts, spring washers, etc. Bolts are used to fasten the gusset plate to the sleeper or pad, while spring washers prevent loosening, ensuring that the fastener system will not loosen under the long-term vibration of the train and maintain a good fastening state.
