Innovation Solution
A novel multi-purpose adjustable hanging beam with two parallel main beams, displacement hangers, screw rods, motors, reduction gearboxes, and a power supply control system that allows dynamic adjustment of hanging points to maintain balance and extend hoisting amplitude, enabling simultaneous hoisting and unloading of multiple objects and single-crane aerial turning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the hanging beam uses a fixed structure with nested balance beams and hanging appliances, then the structure remains simple, but the adaptability and versatility are poor, limiting the use range and functions
Solution Approach 1:
The patent transforms the fixed hanging beam structure into a dynamic, adjustable system. The lower hanging point is made movable along the main beam through a guide groove and sliding mechanism, allowing the hanging position to be adjusted according to different lifting requirements. This dynamic adjustment capability resolves the contradiction by enabling adaptability without requiring complete structural redesign.
Solution Approach 2:
The hanging beam is divided into functional segments: the main beam providing structural support, the adjustable lower hanging point mechanism, and the nested balance beams. This segmentation allows each component to perform its specific function independently, enabling the system to achieve versatility through modular adjustment while maintaining overall structural simplicity.
2Reliability
If the hanging beam uses fixed upper and lower hanging points, then the structure is simple, but the balance performance is poor, requiring accurate manual finding of gravity center positions and load distribution
Solution Approach 1:
The patent incorporates a balance adjustment mechanism that provides feedback on the hanging beam's balance status. The movable lower hanging point allows real-time adjustment of the center of gravity position, enabling the system to self-correct balance issues without requiring precise manual calculation of gravity centers. This feedback mechanism improves reliability while keeping the structure relatively simple.
Solution Approach 2:
The guide groove and sliding mechanism are pre-configured to allow smooth adjustment of the lower hanging point position. This preliminary design enables operators to quickly adjust the balance without complex calculations or procedures, improving balance performance while maintaining operational simplicity.
3Adaptability or versatility
If the hanging beam has fixed hanging points, then the structure is simple, but it cannot meet the requirements of adjustable lifting and hanging weight and amplitude, particularly for extreme amplitude extension and multi-machine operations
Solution Approach 1:
The lower hanging point is designed to move dynamically along the main beam's guide groove, enabling adjustment of both the hanging position and the effective amplitude. This dynamic capability allows the system to meet extreme amplitude extension requirements and supports multi-machine operations by providing flexible positioning, thereby improving adjustability while maintaining ease of operation.
Solution Approach 2:
The adjustable hanging beam is designed as a universal device that can accommodate various lifting scenarios including single-machine and multi-machine operations, extreme amplitude extensions, and different weight distributions. The movable lower hanging point and nested balance beam structure provide multi-functionality, enabling the same device to perform diverse operations without compromising operational flexibility.
