Blade Assembly for Narrow Trenching and Stable Cable Laying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable and pipe laying machines are inefficient in terms of cost and environmental impact, as they require wide trenches that consume more energy and cause significant damage to surfaces, leading to higher environmental disruption and difficulty in covering the trenches.
Innovation Solution
A laying machine with a blade arrangement that cuts narrow trenches, featuring a blade assembly with axially aligned blades and spacer structures to form compartments, which reduces energy consumption and environmental impact by minimizing trench width and facilitating easier covering, while also preventing trench collapse through dust collection and consolidation mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wide trench is used for laying cables or pipes, then the laying machine can accommodate various sizes of conduits, but the energy consumption increases and environmental damage is greater
Solution Approach 1:
The blade arrangement is designed to be adjustable in width and configuration, allowing the cutting width to be dynamically changed according to the specific conduit size being installed. This dynamic adaptability enables the machine to cut narrow trenches for small conduits while maintaining the capability to accommodate larger conduit sizes when needed, thereby reducing energy consumption without sacrificing versatility.
2Adaptability or versatility
If a wide trench is used, then large conduits can be laid, but the trench causes significant damage to road surfaces and requires extensive repair
Solution Approach 1:
The blade arrangement can be dynamically adjusted to match the required trench width, minimizing the cutting width to only what is necessary for the specific conduit size. This reduces the damage to road surfaces and surrounding infrastructure while maintaining the capability to lay large conduits when the blade width is increased to accommodate them.
3Use of energy by moving object
If a narrow trench is cut, then energy consumption is reduced and environmental impact is minimized, but the trench walls are more prone to collapse
Solution Approach 1:
A consolidation device is positioned behind the blade arrangement to immediately compact and stabilize the trench walls as the trench is being created. This preliminary consolidation action prevents wall collapse before it can occur, allowing the machine to cut narrow trenches with minimal energy consumption while maintaining trench wall stability throughout the laying process.
4Ease of operation
If a narrow trench is used, then the trench can be easily covered and made invisible, but the trench requires precise width control to prevent collapse
Solution Approach 1:
The blade arrangement incorporates adjustable width control mechanisms that allow precise adjustment of the cutting width to match the specific requirements of the conduit being installed. This dynamic precision control enables the creation of narrowly defined trenches that are easy to cover while preventing excessive width that could lead to collapse, adapting to different conduit sizes as needed.
