Pipe Lining Transport Assembly Axial Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pipe lining rehabilitation methods face challenges in maintaining the central axis alignment of pipe lining apparatuses due to internal pipe imperfections and bends, leading to improper application of lining material and reinforcing filaments.
Innovation Solution
The pipe lining apparatus features a transport assembly with paired tracks connected to extension/retraction mechanisms, rotational mechanisms, and linear translation mechanisms, allowing for independent movement and adjustment to maintain axial alignment with the pipe, utilizing rocker mechanisms for shock absorption and articulating joints for angular adjustments, and sensor-controlled actuation for autonomous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple transport assembly is used, then device complexity is reduced, but the apparatus cannot maintain axial alignment with pipe bends and imperfections
Solution Approach 1:
The transport assembly incorporates dynamic elements including extension/retraction mechanisms that allow the apparatus to adapt its length, rotational mechanisms that enable angular adjustment to follow pipe bends, and linear translation mechanisms that maintain axial alignment. These dynamic components allow the system to respond to varying pipe geometries while maintaining precision alignment throughout the lining process.
2Manufacturing precision
If extension/retraction mechanisms are added to maintain alignment, then axial alignment is improved, but device complexity increases
Solution Approach 1:
The transport assembly is divided into modular functional segments: extension/retraction mechanisms for length adjustment, rotational mechanisms for angular orientation, and linear translation mechanisms for positional control. Each segment performs a specific function and can be independently controlled, allowing the complex alignment task to be broken down into manageable components that work together systematically.
3Adaptability or versatility
If rotational mechanisms are added to accommodate pipe bends, then adaptability to curved surfaces is improved, but device complexity increases
Solution Approach 1:
Rotational mechanisms are integrated into the transport assembly to provide dynamic angular adjustment capability. These mechanisms allow the apparatus to rotate and follow the curvature of pipe bends, maintaining contact with the curved surface while accommodating changes in pipe orientation. The rotational capability is coordinated with extension/retraction and linear translation mechanisms to achieve smooth navigation through bent sections.
