Scrap Loading Device with Stationary Tilting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for loading scrap into metallurgical melting vessels are inefficient and complex, requiring costly energy for hydraulic or electrical actuation and necessitating a pit for container filling and storage, which prolongs the loading cycle.
Innovation Solution
A device featuring a container with a discharge flap, a guiding system, and a pivotally mounted tilting mechanism with rigid retaining elements for secure transport and unloading, eliminating the need for electrical or hydraulic actuation and a pit, allowing for multiple filled containers to be transported and decoupled from filling and transport processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hydraulic or electrically actuated locking element is arranged on the transport carriage to secure the container, then the container can be securely fixed during transport, but the device complexity and energy consumption increase due to the need for power supply systems
Solution Approach 1:
Instead of arranging the locking mechanism on the moving transport carriage, the invention inverts the arrangement by placing the locking elements (retaining elements) on the stationary guide system. This eliminates the need for power supply to the moving carriage while maintaining secure container fixation during transport.
2Quantity of substance
If a pit is provided for receiving and filling containers with scrap, then containers can be filled and stored, but the loading cycle time increases and the guide system becomes more complex
Solution Approach 1:
The invention applies preliminary action by pre-filling containers with scrap at the scrap yard before transport to the melting plant. This eliminates the need for on-site filling operations and the associated pit infrastructure, thereby reducing loading cycle time and guide system complexity while maintaining adequate scrap supply capacity.
3Ease of operation
If the container is tilted using a movable hydraulic or electric actuator on the transport carriage, then the container can be emptied into the melting vessel, but the device complexity and energy requirements increase
Solution Approach 1:
The invention extracts the actuating mechanism from the moving transport carriage and relocates it to the stationary guide system. The tilting device remains fixed while the transport carriage moves, eliminating the need for power supply to moving components while maintaining the ability to tilt and empty containers efficiently.
4Ease of operation
If a long guide system is used to transport containers from the pit to the loading opening, then containers can be delivered to the melting vessel, but the loading time increases
Solution Approach 1:
By pre-filling containers at the scrap yard and transporting them to the melting plant before the loading operation begins, the invention eliminates the need for a long guide system extending to a pit. The guide system can be shorter since containers are already prepared and positioned closer to the loading point, reducing transport time within the loading cycle.
