Solution Overview
Problem
Current methods for installing Stockbridge dampers on power lines and guy wires require human workers to operate in dangerous environments, necessitating safer and more efficient installation solutions.
Innovation Solution
A robotic Stockbridge damper installer equipped with a frame, motorized wheels, lifting mechanism, and swingarm mechanism is used to traverse along wires, installing dampers using breakaway bolts that shear off at a predetermined torque, allowing for automated and safe damper installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual installation methods are used with human workers, then installation can be performed with simple equipment, but worker safety is compromised due to dangerous working conditions at height
Solution Approach 1:
The robotic installer autonomously performs the complete installation process without human intervention. The system self-navigates along the wire using motorized wheels, self-positions using the swingarm mechanism, self-installs dampers using the breaking bolt mechanism, and self-manages its own movement along the power line, thereby eliminating the need for human workers in hazardous environments
Solution Approach 2:
The patent replaces the manual mechanical installation system with an automated robotic system. The robotic installer uses motorized wheels instead of human climbing, electronic control instead of manual operation, and automated positioning mechanisms instead of human judgment and manual placement, thereby substituting human labor with an automated mechanical-electronic system
2Productivity
If manual installation methods are used, then equipment complexity is low, but installation efficiency and productivity are reduced
Solution Approach 1:
The robotic installer enables continuous installation operations without the interruptions inherent in manual methods. The system can continuously traverse along the power line, continuously position and install dampers at required intervals, and operate without fatigue or breaks, thereby significantly improving installation productivity compared to manual methods
Solution Approach 2:
The robotic installer is designed as a multi-functional system that can perform multiple tasks: traversal along the wire, damper positioning, damper installation, and self-repositioning. This universal system replaces multiple separate operations (climbing, positioning, installing) that would require different equipment or personnel in manual methods, thereby improving overall installation efficiency
3Manufacturing precision
If breakaway bolts are used for damper attachment, then installation precision and security are improved, but the complexity of the attachment mechanism increases
Solution Approach 1:
The breakaway bolt mechanism utilizes a critical parameter change - the bolt is designed with a specific torque threshold that causes it to break at a predetermined force. This parameter-based design ensures precise attachment (the bolt holds firmly during installation) and automatic release (breaks at exact torque specification), providing manufacturing precision through controlled material properties rather than complex mechanical adjustments
