Railway Work Train Continuous Substructure Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for constructing and renovating railway lines require multiple work units and machines, leading to inefficient and costly processes, especially when installing and removing substructure layers, as they often damage the existing substructure, and do not allow for continuous operation.
Innovation Solution
A work train device that enables continuous installation and removal of substructure layers and track laying in one direction, using a separate and decoupled work carriage with conveyor belt technology and special sleeper transport wagons, allowing for simultaneous installation of multiple substructure layers and track components without damaging the substructure, and incorporating reversible conveyor belts for efficient material transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional construction equipment (excavators, rollers) is used to install substructure layers, then installation flexibility is maintained, but installation continuity is interrupted and machine complexity increases
Solution Approach 1:
The patent combines multiple functions (substructure layer installation, track laying, material conveyance) into a single integrated work train system. The ballast finisher, PSS finisher, and conveyor devices are merged into one coordinated unit that operates continuously, eliminating the need for multiple separate machines and enabling uninterrupted installation progress.
Solution Approach 2:
The work train is designed as a multi-functional system that can install both substructure layers (PSS and ballast) and track components simultaneously. The conveyor device serves multiple purposes: transporting material, positioning it precisely, and enabling continuous operation without stopping, thus reducing overall machine complexity while increasing productivity.
2Productivity
If work units operate separately for substructure layers and track, then operational flexibility is maintained, but installation time increases
Solution Approach 1:
The patent implements continuous installation by maintaining constant forward movement of the work train while simultaneously installing PSS layers, ballast layers, and track components. The conveyor device continuously feeds material from the rear to the front, ensuring that all installation operations proceed without interruption and significantly reducing total installation time.
Solution Approach 2:
The system performs preliminary installation of substructure layers (PSS and ballast) before track laying, but in a continuous integrated manner rather than separate phases. The conveyor device pre-positions materials at the exact location where they are needed, allowing the track installation to immediately follow without delays.
3Ease of operation
If vehicles drive on newly laid substructure layers for installation, then installation accessibility is improved, but substructure damage occurs
Solution Approach 1:
The patent introduces a conveyor device as an intermediary mechanism that transports installation materials without requiring vehicles to drive on the freshly laid substructure. The conveyor belt carries ballast and other materials from the rear of the work train to the front, eliminating the need for wheeled vehicles to compaction the PSS layer and preventing substructure damage.
Solution Approach 2:
The patent replaces the traditional mechanical vehicle-based material transport system with a conveyor belt system. This substitution eliminates the harmful mechanical action of vehicle wheels on the soft, newly laid substructure layers, while still providing efficient material transport and installation accessibility through the conveyor mechanism.
4Productivity
If multiple separate machines are used for continuous installation, then installation capability is maintained, but cost-effectiveness decreases
Solution Approach 1:
The patent merges the functions of multiple separate machines into a single integrated work train. The ballast finisher, PSS finisher, and conveyor devices are combined into one unit that performs continuous installation of multiple layers simultaneously, reducing the total number of machines required and improving cost-effectiveness while maintaining high productivity.
