Generator Enclosure Lift Hook Assembly With Rotating Pin Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting solutions for generator enclosures are inefficient as they require multiple lifting points on the sides, which can complicate operations like shipment, installation, and maintenance, and do not effectively consolidate lifting points near the top for improved accessibility and stability.
Innovation Solution
A lifting assembly comprising lifting pins with integrated lift hooks and shafts, and locking assemblies with keyholes, where the pins are rotated to lock within the assemblies, allowing for consolidated lifting points near the top of the generator enclosure, enabling secure lifting and reduced complexity in operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple lifting points on the sides are used, then the generator enclosure can be lifted during shipment and installation, but the operations become complicated and less accessible
Solution Approach 1:
The patent consolidates multiple lifting points into a single integrated lifting assembly located at the top of the generator enclosure. This merging of分散ed lifting points into one centralized structure simplifies the lifting operation and improves accessibility while maintaining the ability to lift the enclosure during shipment and installation.
Solution Approach 2:
The lifting assembly is designed to perform multiple functions: it serves as both a lifting mechanism and a structural component of the generator enclosure. The assembly can be used for various operations including shipment, installation, and maintenance, making it a universal solution that eliminates the need for separate lifting points throughout the structure.
2Reliability
If lifting points are consolidated near the top, then operational ease and safety are enhanced, but the structural design becomes more complex
Solution Approach 1:
The lifting assembly is pre-integrated into the generator enclosure structure during manufacturing, with lifting pins and locking mechanisms already in place. This preliminary integration ensures that the lifting points are structurally sound and safely positioned at the top of the enclosure before actual lifting operations begin, enhancing reliability while managing structural complexity through advance planning.
Solution Approach 2:
The lifting assembly incorporates movable components such as rotatable lifting pins and locking mechanisms that can dynamically adjust between locked and unlocked positions. This dynamic design allows the structure to transition from a compact enclosed state to an open lifting state, providing safety during transport while enabling easy access during maintenance operations.
3Strength
If lifting pins are rotated to lock position, then secure lifting is achieved, but the mechanism requires more steps to operate
Solution Approach 1:
The lifting pin mechanism is designed to be self-locking through its own rotational motion. When the lifting pin is rotated into the locked position, its geometry automatically engages with the locking assembly without requiring separate locking actions or additional steps. This self-service mechanism maintains strong locking security while minimizing the number of operational steps required.
