How to accurately install spiral spikes

Fasteners, as the key connecting components between rails and sleepers, have the core function of firmly fixing the rails on the sleepers, thereby ensuring the stability of the track gauge and effectively preventing the rails from moving in the longitudinal and transverse directions on the sleepers.

Spiral spikes, as an important component of railway fasteners, are one of the indispensable accessories in railway track transportation.
To ensure the safe and smooth operation of trains, the railway tracks must apply appropriate buckling pressure, which is mainly achieved through the fastener system. The state of the spiral spikes, as the core component in the fastener system, directly determines whether the entire system can function efficiently.

To ensure the safe and smooth operation of trains, the spiral spikes must be in good condition. This includes ensuring the quality of the spikes and correctly installing and anchoring the spiral spikes.

The spiral spikes are directly inserted into them by pouring sulfur anchoring agent. After the anchoring agent is completely solidified, the assembly and anchoring of the spikes can be completed.

The operator's technical level is significantly affected, and a slight hand shake may cause the installation of the spikes to be crooked. If the deflection angle is too large, it will significantly increase the complexity of subsequent line maintenance. At the same time, the anchoring agent will overflow and be difficult to remove after solidification. However, by cleverly using the positioning frame, the spiral spikes can be easily installed accurately and quickly to ensure accuracy.

The design principle of the spiral spike positioning frame is closely related to the sleeper structure, and is designed to provide precise positioning for the installation of spiral spikes. Different types of sleepers need to be used with corresponding types of positioning frames to ensure the accuracy of installation height and position.
