Chain-Install Apparatus for Conveyor Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of chains in industrial conveyor systems, such as cathode stripping machines, is labor-intensive and poses safety hazards due to the difficulty in handling long, heavy metal chains, and existing solutions often do not comply with safety standards for lifting systems, leading to unsafe and inefficient installation processes.
Innovation Solution
A chain-install apparatus comprising a support structure, hub assembly, brake assembly, and attachment arrangement that allows for controlled and balanced lifting and feeding of chains into conveyor systems, complying with ASME standards for below-the-hook lifting devices, and enabling safe and efficient installation of chains without the need for manual labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If chains are installed using manual labor from ground level, then safety standards for lifting systems are avoided, but the installation process becomes labor-intensive and time-consuming
Solution Approach 1:
The patent introduces a chain-install apparatus as an intermediary device between the operator and the chain. This apparatus includes a support structure with a hub assembly that can be lifted by a crane, allowing the chain to be fed from an elevated position. The brake assembly acts as a mediator to control the chain feed rate, enabling safe and efficient installation without direct manual handling of heavy chains.
Solution Approach 2:
The patent replaces manual mechanical handling with a mechanical lifting and feeding system. The hub assembly with brake mechanism substitutes for manual labor in controlling chain movement, while the crane provides mechanical lifting capability. This substitution eliminates the need for workers to manually handle heavy chains at ground level, improving both safety and efficiency.
2Productivity
If chains are handled manually, then equipment complexity is minimized, but the heavy metal chains become difficult to handle and require significant time and personnel
Solution Approach 1:
The patent segments the chain-installation process into distinct functional components: a support structure for positioning, a hub assembly for chain winding and feeding, a brake assembly for rate control, and an attachment arrangement for crane coupling. This segmentation allows each component to perform its specific function efficiently, achieving high installation speed while keeping individual component complexity manageable.
Solution Approach 2:
The hub assembly serves multiple functions: it acts as a support for the chain, a feeding mechanism through controlled unwinding, and a braking system for rate control. The attachment arrangement provides both structural support and crane coupling capability. This multi-functionality reduces the need for separate devices, improving productivity without proportionally increasing overall system complexity.
3Ease of operation
If chains are lifted and installed from above, then installation control and safety are improved, but compliance with safety standards for lifting systems becomes required
Solution Approach 1:
The brake assembly serves as a critical intermediary safety mechanism between the lifted hub assembly and the chain. It provides controlled braking force to manage the chain feed rate, preventing uncontrolled descent or excessive tension. This intermediary control system enables safe lifting operations while maintaining compliance with safety standards through deliberate, controlled mechanical braking rather than uncontrolled gravity-driven installation.
