AI Technical Summary

Technical Problem

Existing railway track renewal and construction processes face challenges in efficiently moving stacks of sleepers between wagons, particularly due to the complexity of gantry systems which complicate stability and safety, especially during curved trajectories and high-speed movements.

Method used

A mechanism for moving stacks of sleepers that includes guide and drive means to facilitate the back-and-forth movement of carriages between two positions, interconnected carriages to form a transport structure, and a lifting mechanism to adjust support planes, ensuring stability and safety without the need for complex gantry systems.

Benefits of technology

This solution allows for stable and efficient movement of sleepers between wagons, improving safety and reducing the complexity of operations, especially during curved paths and high-speed movements, by eliminating the need for gantries and enhancing the overall stability of the railway vehicle.

Abstract

The invention relates to a mechanism for moving stacks (21', 22') of sleepers (21, 22) intended to equip a railway track, the moving mechanism (130) being intended to equip at least two successive work wagons (100, 200, 300) of a railway vehicle (1), the moving mechanism (130) comprising guiding means (140) configured to guide, along a longitudinal direction (X) of each of the wagons, a plurality of trolleys (131) adjacent in pairs, the moving mechanism (130) comprising drive means (150) for moving the trolleys (131) jointly back and forth between a first and a second moving position such that each trolley (131) carries a stack (21', 22') of sleepers (21, 22) along a path (W1) from the first to the second displacement position, and configured to traverse a return path (W2), from the second to the first displacement position,by being discharged.
