Reconfigurable Roller Table for Converter Lining Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing lining machines for steel converters face challenges in efficiently transporting and positioning refractory materials due to limited directional movement and long travel paths, leading to increased wear and replacement frequency of the converter lining.
Innovation Solution
A transport apparatus with a dual-position roller table system and multiple removal tables allows for flexible movement in two directions, reducing travel paths and enabling efficient loading and unloading of materials onto working platforms, combined with a modular lining machine design for quick assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single-direction roller table is used for transporting refractory material, then the transport path is simple, but the travel path becomes long and material delivery efficiency decreases
Solution Approach 1:
The roller table is designed with movable roller frames that can be positioned in different configurations. The first roller frame and second roller frame can be arranged in a first configuration for unidirectional transport or a second configuration for bidirectional transport, allowing the system to adapt its complexity based on operational needs
Solution Approach 2:
The roller table is divided into separate roller frames (first roller frame, second roller frame) with independent roller arrangements. This segmentation allows each frame to be positioned independently to create different transport paths, enabling both simple and complex transport modes as needed
2Adaptability or versatility
If a fixed roller table configuration is used, then the device structure is simple, but the adaptability to different working platforms is limited
Solution Approach 1:
The roller frames are designed to be movable and reconfigurable rather than fixed. The first and second roller frames can be repositioned to accommodate different working platform positions and orientations, providing adaptability without requiring multiple dedicated roller tables for each platform
Solution Approach 2:
The single roller table system with reconfigurable roller frames serves multiple working platforms (first working platform, second working platform) that are offset from each other. This universal design eliminates the need for separate dedicated transport systems for each platform
3Loss of time
If long travel paths are used for material transport, then the transport apparatus structure is simple, but the lining renewal time increases
Solution Approach 1:
The movable roller frames enable dynamic adjustment of transport paths to optimize material delivery routes. By repositioning the roller frames, the system can create shorter, more direct paths to different working platforms, reducing the time required for material transport during lining renewal operations
Solution Approach 2:
The system utilizes three-dimensional space by positioning roller frames at different heights and orientations. The first and second roller frames can be arranged in vertical and horizontal configurations, creating multiple transport dimensions that shorten the effective path length compared to single-plane transport systems
