Product Introduction
The railway fastener system is an important part of the railway track. Its function is to firmly fix the rails on the sleepers, ensure the stability of the track geometry, and ensure the safe operation of the train. The system is mainly composed of fasteners, pads, anchor parts, etc. Through different structural designs and material selections, it has derived various types such as SKL, KPO, Nabla, WJ-8 and E-type to meet the needs of different railway scenarios.
WJ-8 type fastener system: specially designed for high-speed railway ballastless tracks, it consists of spring bars, insulating gauge blocks and rail pads. The spring bars provide buckling pressure to ensure the stability of the rails; the insulating gauge blocks use insulating materials to prevent the stray current of the electrified railway from corroding the track structure; the rail pads play a buffering and vibration reduction role. The WJ-8 system has high gauge adjustment accuracy and excellent insulation performance. It is the main fastener system for high-speed railway construction, such as the Beijing-Guangzhou High-speed Railway and the Harbin-Dalian High-speed Railway.
WJ-8 type fastener structural features and advantages:
Stable structure: It is an elastic non-separable fastener with an iron pad. Concrete shoulders are set on concrete sleepers or track slab bearing grooves. The lateral load of the train is transmitted to the concrete shoulders through the iron pads and the gauge baffles, which reduces the position of the lateral load and makes the structure more stable. The spiral spikes are basically simply tensile, ensuring the long-term reliability of the connection with the nylon sleeve.
Good elasticity: An elastic cushion layer is set under the iron pad, using long-life thermosetting elastomer materials. The fastener system has good elasticity and can effectively absorb the impact and vibration energy of the train operation and reduce the wear of track components.
