Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting and guiding devices for wind turbine tower sections often cause scratches and damage during installation due to direct contact between segments, which complicates handling and increases the risk of surface damage.
Innovation Solution
A lifting and guiding device with a support part and a rotatable part that maintains a secure distance between tower segments, featuring through holes for secure attachment, a curvature matching the tower section, and rotatable parts to prevent collision and facilitate axial movement, along with attachments for crane equipment and securing lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If crane equipment is connected directly to tower sections for lifting, then lifting operation is simplified, but the treated surface of the sections is scratched and damaged
Solution Approach 1:
The patent introduces a lifting device as an intermediary between the crane equipment and the tower section. This lifting device includes a support part that contacts the tower section and a rotatable part that interfaces with the crane, preventing direct contact between the crane and the tower section surface, thereby avoiding scratches while enabling lifting operations
2Productivity
If tower sections are handled directly during installation, then handling process is simplified, but segments collide and cause scratches on the treated surface
Solution Approach 1:
The lifting device serves as a mediator during the installation process, with the rotatable part maintaining a secure distance between segments. This prevents direct collision between segments while allowing efficient handling and axial movement during installation
3Productivity
If segments are allowed to approach each other freely during installation, then installation speed is increased, but precise alignment and connection cannot be ensured
Solution Approach 1:
The rotatable part of the lifting device changes the spatial parameter by maintaining a predetermined secure distance between segments. This controlled distance parameter enables both fast installation and precise alignment, as the segments are guided into correct axial position during the installation process
