Lateral Rail Transport Device for Track Maintenance Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current track maintenance vehicles face challenges in efficiently and simply transporting long rails for maintenance operations without compromising their versatility for other maintenance tasks.
Innovation Solution
A rail transport device is integrated on the machine frame, allowing for lateral displacement along the longitudinal beam using a displacement drive, enabling the transport of up to 20-meter long rails while maintaining the vehicle's operability for other maintenance operations, and allowing for retrofitting of existing machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rail transport device is integrated on the machine frame, then rail transport capability is improved, but device complexity increases
Solution Approach 1:
The rail transport device is segmented into a carriage body, displacement drive unit, and loading/unloading mechanism that can operate independently from the main track maintenance vehicle system. This allows the transport function to be added without redesigning the entire vehicle architecture.
Solution Approach 2:
The rail transport device is designed to be universally applicable to existing track maintenance vehicles by utilizing the standard machine frame and longitudinal beam structure. The displacement drive can operate with the existing crane system, allowing one device to serve multiple functions: rail transport, loading, unloading, and compatibility with existing maintenance operations.
2Ease of operation
If the rail transport device is made displaceable in the transverse direction, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The rail transport device incorporates a displacement drive that enables dynamic adjustment of the carriage position in the transverse direction along the longitudinal beam. This allows the device to move between different operational positions (loading position, transport position, unloading position) to adapt to various operational requirements without requiring complex manual manipulation.
3Ease of manufacture
If the rail transport device is arranged laterally on the longitudinal beam, then ease of manufacture is improved, but device complexity increases
Solution Approach 1:
The rail transport device is merged with the existing longitudinal beam structure of the machine frame. The carriage is mounted on the longitudinal beam, utilizing the beam's structural elements (flanges and web) as part of the support and guidance system. This integration allows the transport device to be manufactured and installed as a single assembled unit rather than requiring separate structural components.
4Adaptability or versatility
If the vehicle maintains versatility for other maintenance operations, then adaptability is improved, but device complexity increases
Solution Approach 1:
The rail transport device is designed to be universally compatible with existing track maintenance vehicle systems. The displacement drive operates within the existing machine frame constraints, and the carriage can work with the standard crane system for loading and unloading rails. This universal design allows the vehicle to perform both rail transport and other maintenance operations without requiring separate specialized equipment.

AI summary
A longitudinal beam of a track maintenance vehicle is connected at a beam exterior side—facing away from the opposite longitudinal beam—to a rail transport device provided for receiving rails. The rail transport device is displaceable by means of a displacement drive in the transverse direction of the machine relative to a machine frame within a displacement path s delimited by a transport—and a loading position.
