Modular Rail Trolley With Reversible Conveyor For Ballast Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing railway track construction and rehabilitation technologies are limited by the complexity and specificity of ballast cleaning machines, which are designed for a single purpose and cannot be flexibly integrated into modular work trains for universal use.
Innovation Solution
A modular work wagon with reversible conveyor belts and a processing device that can be integrated into a series of material-conveying silo wagons, allowing for flexible logistical transport and processing of ballast and substructure materials without requiring specific installation or removal units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ballast cleaning machines are designed with specific removal and reinstallation units, then cleaning functionality is achieved, but device complexity and lack of versatility increase
Solution Approach 1:
The work wagon is designed with conveyor belts that can operate in multiple directions and configurations to perform different functions. The same conveyor system can transport ballast for cleaning operations, move materials between wagons, or facilitate reinstallation tasks, eliminating the need for separate specialized units for each function.
Solution Approach 2:
The work train is divided into modular work wagons, each with independent conveyor systems. This segmentation allows each wagon to be configured for specific tasks while maintaining overall system flexibility. The conveyor belts in each wagon can be independently controlled to adapt to different operational requirements.
2Adaptability or versatility
If conveyor belts are fixed in transport direction, then structural simplicity is maintained, but adaptability and flexibility decrease
Solution Approach 1:
The conveyor belts are designed with reversible drive mechanisms that allow change in transport direction during operation. This dynamic capability enables the same conveyor system to adapt to different material flow requirements, such as transporting ballast forward for cleaning or reversing to move processed materials backward to adjacent wagons.
Solution Approach 2:
The operational parameters of the conveyor belts, particularly the direction of material transport, can be changed during operation. The drive systems are configured to allow reversal of belt movement direction, enabling flexible adaptation to various operational scenarios without requiring separate conveyors for each direction.
3Ease of operation
If work wagons are designed for specific tasks, then functional effectiveness is improved, but ease of operation and reconfiguration decrease
Solution Approach 1:
The work train consists of segmented modular wagons that can be independently configured and repositioned. Each wagon maintains its core cleaning functionality while the modular design allows easy reconfiguration of the train sequence to adapt to different track sections and operational requirements.
Solution Approach 2:
Each work wagon is designed with universal conveyor systems that can perform multiple functions depending on configuration. The same wagon can be used for ballast removal, cleaning, or reinstallation tasks by adjusting conveyor directions and connections to adjacent wagons, maintaining functional effectiveness while improving reconfiguration ease.

AI summary
The trolley (5,6) has a reprocessing unit (17) either for ballast (10), for sub-materials, for a full or partial replacement or for an evacuation. The ballast or the sub-material are removable and re-installable by the reprocessing unit. The trolley is designed in such a modular manner that it is inserted at any string sort of other trolleys of a working train. A conveyor belt of the trolley is used with the reprocessing unit in a base area or in a roof area for transportation of materials to or from a specific location of a machine area adjacent to the other trolleys of the working train.
