Roll-off Transport Device Pivot Joint Maneuverability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roll-off transport devices have limited maneuverability due to restrictive mounting brackets and uncontrolled movement of the loading arm hook, which restricts their application, especially in situations requiring extensive maneuvering between the swap body vehicle and the transport device.
Innovation Solution
The introduction of a pivot joint in the loading arm connection, allowing rotational movement relative to the connecting and bottom structures, along with ground rollers and slide rails, enhances maneuverability and stability, enabling more controlled and extensive movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a support bracket is used for the loading arm connection, then the structure is simple and stable, but the maneuverability is extremely limited (less than 60°) and the loading arm hook moves uncontrolled
Solution Approach 1:
The loading arm connection is transformed from a static support bracket to a dynamic pivot joint that enables controlled rotational movement. The pivot joint allows the loading arm connection to rotate relative to the connecting structure, providing maneuverability while maintaining structural integrity through defined rotational constraints.
2Adaptability or versatility
If the loading arm connection is made rigid for stability, then the structure is stable, but the maneuvering range is restricted to less than 60°
Solution Approach 1:
The pivot joint introduces controlled dynamics to the loading arm connection, allowing it to adapt its position through rotation while maintaining stability through the defined pivot mechanism. This enables maneuvering ranges exceeding 60° without compromising the structural stability during operation.
Solution Approach 2:
The rotational parameter of the loading arm connection is changed from fixed (less than 60°) to variable (greater than 60°) through the pivot joint mechanism. This parameter change allows the connection to achieve broader maneuvering ranges while maintaining operational stability through the constrained rotational movement.
3Ease of operation
If the loading arm hook is allowed to move freely during maneuvering, then the maneuverability is improved, but the roll-off transport device becomes unstable in extreme situations
Solution Approach 1:
The pivot joint acts as an intermediary between the loading arm connection and the connecting structure, mediating the movement and forces during maneuvering. It allows controlled rotation while constraining uncontrolled movement, thereby maintaining stability in extreme situations while enabling improved maneuverability.
Solution Approach 2:
The degrees of freedom parameter of the loading arm connection is changed from fully constrained (fixed position) to partially constrained (controlled rotation) through the pivot joint. This parameter modification enables maneuverability while preventing uncontrolled movement that would compromise stability.
