Vacuum Circuit Breaker Lift Hook Storage for Easier Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vacuum circuit breakers face difficulties in securely mounting and demounting lift hooks, necessitating manual handling and causing inconvenience during maintenance operations.
Innovation Solution
A vacuum circuit breaker design featuring a storage-type lift hook with movable fixing bolts that allow the lift hook to be mounted on the circuit breaker main body, enabling easy upward and downward movement without additional attachments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lift hooks are fixedly mounted on the vacuum circuit breaker using assembly holes and bolts, then the lift hooks can be securely attached for crane operations, but the user must manually mount and demount the lift hooks, causing inconvenience and time loss
Solution Approach 1:
The lift hook is designed with movable characteristics, allowing it to be easily attached to and detached from the vacuum circuit breaker body. The hook can slide along the breaker body and be quickly positioned, transforming the static fixed-mounting approach into a dynamic easily-adjustable system that maintains security while improving operational convenience
Solution Approach 2:
The vacuum circuit breaker body is designed with integrated mounting structures (such as grooves or rails) that enable the lift hook to self-align and attach without requiring separate assembly tools or complex procedures. The breaker body itself provides the mounting function, eliminating the need for external assembly operations
2Ease of operation
If additional assembly holes and bolts are provided for lift hooks, then the lift hooks can be mounted, but the device structure becomes more complex and requires additional components
Solution Approach 1:
The vacuum circuit breaker body is designed with multi-functional characteristics, where the same structural features serve both as mounting elements for lift hooks and as integral parts of the breaker housing. This eliminates the need for separate dedicated mounting components, reducing overall device complexity while maintaining the ability to securely attach lift hooks
Solution Approach 2:
The mounting structures for lift hooks are merged with the vacuum circuit breaker body structure itself. Rather than being separate add-on components, the mounting features are integrated into the breaker housing, combining multiple functions into a unified structure that reduces the total number of parts
