Rail Welding Shearing Device with Pivotable Side Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing welding units for rail tracks face challenges in efficiently welding rails above sleepers due to limitations in their design, particularly in removing weld beads and maintaining stability during the process.
Innovation Solution
The welding unit incorporates a tooth system in the rail base sections for a form-locking connection in the longitudinal direction, allowing for improved stability and ease of weld bead removal, with a shearing device featuring pivotable side parts and a head part with a shearing edge, enabling welding above sleepers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the rail base sections are designed with a tooth system for form-locking connection, then welding above sleepers becomes possible and stability is improved, but the device complexity increases
Solution Approach 1:
The rail base sections are divided into modular components with integrated tooth systems. Each rail base section is a self-contained unit with form-locking teeth that can be independently manufactured and assembled, reducing overall system complexity while maintaining stability during welding operations above sleepers.
Solution Approach 2:
The tooth system extends the form-locking connection into the longitudinal dimension of the rail. By adding teeth that engage in the longitudinal direction, the connection gains additional stability without requiring increased height or complexity in the vertical dimension, enabling welding above sleepers while controlling device complexity.
2Adaptability or versatility
If the side parts are made pivotable towards one another, then the shearing device can adapt to different positions, but the device complexity increases
Solution Approach 1:
The side parts are designed with pivotable joints that allow dynamic adjustment of the shearing device configuration. This enables the device to adapt to different rail positions and welding scenarios while maintaining a relatively simple mechanical structure through the use of standardized pivot connections rather than complex adjustment mechanisms.

AI summary
A welding unit for welding rails of a track includes a shearing device for removing a weld bead. The shearing device includes a head part having a shearing edge and two side parts which are pivotable towards one another and have a shearing edge. A rail base section to be applied to a rail base is associated with each side part. The rail base sections each include an end region facing towards each another having a tooth system for a form-locking connection which is effective in a longitudinal direction of the rail after the two side parts have been applied to the rail.
