Rail Welding Alignment System with Dual Chassis

The patent combines the clamping function and tensioning function into a single integrated system. The puller assembly simultaneously clamps both rail sections and applies tension, eliminating the need for separate heavy cylinders at each end. This merging of functions reduces the overall weight and bulk of the welding device while maintaining sufficient clamping force through the mechanical advantage of the integrated mechanism.

The patent replaces the manual straightedge alignment method with an induction-based alignment system. The induction welding unit incorporates alignment mechanisms that use electromagnetic fields and precision mechanical guides to automatically align rail sections with high precision. This substitution of mechanical alignment tools with more advanced alignment technology significantly improves measurement precision while reducing operator intervention.

The patent implements preliminary alignment actions before the welding process begins. The system includes alignment mechanisms that precisely position and align rail sections prior to induction heating and welding. This preliminary alignment ensures that the rail sections are accurately positioned before the welding operation starts, maintaining high alignment control throughout the process while preserving welding productivity.

The patent designs the welding device with universal multi-functional components that perform multiple operations. The puller assembly serves both clamping and tensioning functions, the induction heating unit integrates alignment and heating capabilities, and the control system manages multiple functions through a unified interface. This multi-functionality approach reduces the need for separate dedicated components, thereby managing device complexity while maintaining high adaptability and versatility.
