Overhead Conveying Vehicle Suspension for Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing overhead conveying vehicles with a configuration where the main body part holding the conveyed object is suspended and supported by the traveling part cannot effectively suppress vibration propagation from the traveling part to the conveyed object.
Innovation Solution
The overhead conveying vehicle incorporates a base unit suspended by the traveling part, with a horizontal shaft integrally provided and supported by a rubber bush, and optionally paired with dampers, to absorb and damp vibrations, maintaining the relative positional relationship between the traveling part and the main body part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the main body part is suspended and supported by the traveling part in an overhead conveying vehicle, then the structure can be simplified and the conveyed object can be easily transported, but vibration from the traveling part propagates to the conveyed object causing instability
Solution Approach 1:
A rubber bush is introduced as an intermediary component between the traveling part and the main body part. The rubber bush absorbs vibrations from the traveling part before they can propagate to the conveyed object, while still allowing the suspended support structure to function. This mediator resolves the contradiction by blocking harmful vibrations without requiring a completely different structural configuration.
2Object-affected harmful factors
If a rubber bush is added to connect the traveling part and main body part, then vibration propagation is suppressed, but the device complexity increases
Solution Approach 1:
Instead of redesigning the entire suspension structure, the rubber bush is applied locally at the specific connection point between the traveling part and main body part. This localized application of vibration isolation material effectively suppresses vibration propagation while adding minimal complexity to the overall system.
3Stability of the object's composition
If the horizontal shaft is disposed to extend in a direction orthogonal to both traveling direction and vertical direction, then angular change is restricted to traveling direction only, but the device complexity increases
Solution Approach 1:
The horizontal shaft is configured to extend in a specific asymmetric direction (orthogonal to both traveling direction and vertical direction) rather than allowing rotation in all directions. This asymmetric orientation restricts angular changes to only the traveling direction, preventing tilting that would affect lateral transfer stability while maintaining a relatively simple shaft structure.

Function Achieved in This Case
This configuration effectively suppresses vibration propagation to the conveyed object, minimizes tilting, and stabilizes the positional relationship between the traveling and main body parts, enhancing the stability and vibration damping capabilities of the vehicle.
Implementation Method 1
vibration transmitted from the traveling part to the base unit is absorbed by the rubber bush
