Intermediate Work Wagon Bidirectional Conveyor Material Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional material transport silo wagons can only supply or discharge a single building material at a time, limiting flexibility in material transfer between wagons and transfer points within a work train.
Innovation Solution
A work train configuration with an intermediate work wagon featuring opposing conveyor belts and a bridge conveyor belt allows for flexible material transfer between any two material transport silo wagons or transfer points, enabling bidirectional operation and reversible positioning of conveyor belts for universal material flow management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional material transport silo wagons are used with single-direction conveyor belts, then the structure is simple, but only a single building material can be supplied to the construction site at a time
Solution Approach 1:
The patent applies dynamics by making the conveyor belts reversible in direction. The intermediate work wagon's conveyor belts can change their conveying direction dynamically to adapt to different material transfer requirements, enabling flexible supply of multiple building materials while maintaining a relatively simple overall structure.
Solution Approach 2:
The intermediate work wagon is designed with multi-functionality, serving as a universal transfer point that can handle various material transfer operations between different work wagons. Its conveyor belts can operate in different directions and configurations to support multiple building material supply scenarios.
2Adaptability or versatility
If transfer conveyor belts are fixed at wagon ends, then the loading/unloading process is simple, but material cannot be transferred between any arbitrary wagons in the train
Solution Approach 1:
The intermediate work wagon acts as an intermediary element between two work wagons, providing a flexible transfer point with conveyor belts that can be positioned and oriented to enable material transfer between any arbitrary wagons in the train, not just adjacent ones.
Solution Approach 2:
The conveyor belts of the intermediate work wagon are designed to be reversible and adjustable in direction, allowing dynamic adaptation to different transfer scenarios. This enables material to be transferred from any wagon to any other wagon by appropriately configuring the intermediate wagon's conveyor system.
3Ease of operation
If only single-direction conveyor belts are used, then the conveying system is simple, but bidirectional material transfer between wagons is not possible
Solution Approach 1:
The patent implements bidirectional material transfer by making the conveyor belts reversible in direction. The intermediate work wagon's conveyor belts can change their conveying direction dynamically, allowing material to be moved in either direction along the train without requiring separate conveyor systems for each direction.

AI summary
The intermediate work vehicle (7) has a work train (1) for developing or reconstructing a railway line consisting of a base structure and rails. A material from a roof conveyor (6) of a work vehicle (2) is placed into the container of the same work vehicle. The material from the container of a work vehicle is superimposed on the roof conveyor of the same work vehicle and is placed from the roof conveyor of the work vehicle into the container of the other work vehicle.
