Wellbore Track Synchronization for Stable Wire Rope Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wellbore inspection methods in mining are inefficient, costly, and prone to misjudgment due to the difficulty in detecting subtle changes and achieving synchronization of wire rope movement along the circumferential direction of the wellbore wall, leading to potential accidents like fracture and water inrush.
Innovation Solution
A synchronous movement apparatus comprising upper and lower moving tracks with wire rope moving devices and a control system that uses position detection devices to ensure synchronized movement by adjusting the drive motors, preventing wire rope deflection and ensuring continuous inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If wire rope moving devices move along the circumferential direction of a wellbore wall, then inspection coverage is improved, but wire ropes deflect due to different moving speeds
Solution Approach 1:
The patent employs position detection devices that detect the positions of moving rollers on upper and lower moving tracks, feeding back position information to a control device. The control device adjusts the drive motors based on this feedback to ensure both wire rope moving devices move at the same speed, preventing wire rope deflection while maintaining inspection coverage.
Solution Approach 2:
The control device dynamically adjusts the operating parameters (speed) of the drive motors based on real-time position feedback. By changing the speed parameter of the motors, the system ensures synchronized movement of wire rope moving devices, preventing wire rope deflection during circumferential movement along the wellbore wall.
2Ease of manufacture
If manual inspection methods are used, then implementation simplicity is maintained, but inspection efficiency is low and misjudgment rates are high
Solution Approach 1:
The inspection system performs self-inspection through automated wire rope moving devices that carry inspection equipment along the wellbore. The system autonomously detects wellbore conditions, eliminates manual intervention, and provides continuous monitoring, thereby dramatically improving inspection efficiency while maintaining operational simplicity through automated control.
Solution Approach 2:
The patent replaces manual mechanical inspection with an automated system using wire rope moving devices equipped with sensors and detection equipment. This substitution of manual mechanical operations with automated mechanical-electrical systems improves inspection efficiency and reduces misjudgment rates while keeping the overall system relatively simple to implement.
3Duration of action of moving object
If wire rope moving devices are used for circumferential inspection, then inspection continuity is improved, but synchronization control becomes complex
Solution Approach 1:
The control system continuously receives position feedback from detection devices monitoring the moving rollers on both upper and lower tracks. This real-time feedback enables the control device to maintain synchronization of the wire rope moving devices throughout the circumferential inspection process, ensuring inspection continuity without excessive control complexity.
Solution Approach 2:
The system maintains synchronized movement of wire rope moving devices by keeping them at equivalent operational states through position feedback and motor adjustment. This equipotential approach ensures both devices remain in corresponding positions during circumferential movement, maintaining inspection continuity while simplifying synchronization control through standardized position matching.
