Trailing Vehicle Support Frame Displacement for Wind Turbine Blade Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trailer vehicles for transporting wind turbine rotor blades face challenges in maneuverability and agility due to fixed overhangs, which complicate cornering and increase the risk of damage during transport, especially for blades longer than 65 meters.
Innovation Solution
A trailer vehicle with a displacement device that allows the support frame to move relative to the pivot bearing along the longitudinal direction of the rotor blade, enabling adjustment of the overhang between the towing vehicle and the trailer vehicle, thereby improving maneuverability and adaptability to different transport conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the support frame is fixedly connected to the pivot bearing, then the structural stability is improved, but the maneuverability and agility deteriorate due to fixed overhang
Solution Approach 1:
The support frame is made dynamically adjustable relative to the pivot bearing through the displacement device. The frame can be positioned at different locations along the longitudinal direction of the rotor blade, allowing the overhang to be changed between shunting runs and normal transport operations. This dynamic adjustment capability enables the system to adapt to different operational requirements, improving both maneuverability during cornering and structural stability during transport.
2Device complexity
If the overhang is fixed, then the device complexity is reduced, but the adaptability to different transport conditions deteriorates
Solution Approach 1:
The displacement device enables dynamic adjustment of the support frame position along the longitudinal direction of the rotor blade. This allows the overhang to be adapted to different transport conditions - shorter overhang for shunting runs with tight cornering requirements, and longer overhang for normal transport operations. The system maintains relatively simple construction while providing the necessary adaptability through this adjustable mechanism.
3Ease of operation
If the support frame is displaceable relative to the pivot bearing, then the maneuverability is improved, but the device complexity increases
Solution Approach 1:
A displacement device is introduced as an intermediary mechanism between the support frame and the pivot bearing. This device includes a displacement platform that can move along the longitudinal direction of the rotor blade and is guided by guide elements on the pivot bearing. The intermediary mechanism enables the support frame to be displaced and repositioned, thereby improving maneuverability and agility during cornering operations without requiring complete redesign of the entire support system.
