Drill Cable Stinger Guidance to Prevent Chip Ingress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In blast hole drilling, the drill trail cable often drags across chip piles, causing chips to fall back into the drill holes, leading to interruptions and increased costs due to manual repositioning and potential cable damage.
Innovation Solution
A drill trail cable management system featuring a stinger with a beam extending from a platform to guide the cable away from chip piles, combined with a cable reel and propulsion system to automate cable positioning and tension control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the drill trail cable is allowed to drag across chip piles, then cable tension and drag are reduced, but chips fall back into drill holes causing interruptions and manual repositioning is required
Solution Approach 1:
A stinger is introduced as an intermediary component between the cable reel and the drill trail cable. The stinger actively guides and positions the cable away from chip piles, preventing chips from falling into the drill hole while maintaining cable tension and avoiding the need for manual repositioning.
2Object-affected harmful factors
If manual repositioning of the cable is performed, then chip ingress is prevented, but operational time is lost and productivity decreases
Solution Approach 1:
The stinger is equipped with actuators that enable it to automatically adjust and reposition the cable without human intervention. The system self-regulates cable position to prevent chip ingress, eliminating the need for manual repositioning operations and associated time losses.
3Device complexity
If the cable reel is removed completely, then device complexity is reduced, but cable management capability is lost
Solution Approach 1:
The cable management system is segmented into distinct functional components: the cable reel for cable storage and deployment, and the stinger with actuators for active cable positioning and guidance. This segmentation allows each component to perform its specialized function efficiently while working together as an integrated system.

AI summary
A device including a platform and a drill connected to the platform. The device also includes a power source for powering the drill. The device also includes a cable connected to a cable reel and to the drill. The device also includes a stinger having a first end connected to the platform and a second end opposite the first end. The stinger includes a beam extending outwardly from the platform. The second end of the stinger connects to the cable. The stinger is configured to guide a position of the cable, relative to the platform, as the cable moves relative to the platform and relative to the stinger.
