Alpine Anchor Plug Coupling for Safe Rod Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of threaded rods in alpine anchors is challenging due to the need for manual handling and risk of accidents, especially with long rods, as existing methods require free-hand operation and can result in improper clamping or breakage during anchoring in soil or rock.
Innovation Solution
A detachable plug-in coupling system between the assembly machine and the base plate, featuring shaped receptacles for non-rotatable engagement, allows for torque-proof coupling, eliminating the need for manual force and ensuring safe and reliable installation of threaded rods up to 12 meters in length without accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a freehand drilling machine is used to drive threaded rods into the base plate, then the threaded rods can be anchored in the ground or rock, but the operator faces significant safety risks including improper clamping, rod ejection, breakage, or jamming
Solution Approach 1:
The patent introduces a coupling device as an intermediary component that connects the drilling machine to the base plate. This coupling device includes a coupling element with a reception space that securely holds the threaded rod, and a coupling body that attaches to the base plate. The intermediary coupling device transfers the driving force from the drilling machine to the threaded rod while preventing improper clamping, ejection, or breakage, thus resolving the safety issues of freehand operation without requiring manual handling
2Length of moving object
If threaded rods up to 6 meters in length are driven manually, then anchoring can be achieved, but the risk of injury increases due to improper clamping and potential rod ejection
Solution Approach 1:
The coupling device serves as an intermediary that provides a secure connection between the drilling machine and long threaded rods. The reception space in the coupling element is designed to accommodate the threaded rod with proper support, ensuring reliable clamping throughout the driving process. This eliminates the risks associated with manual clamping of long rods, allowing threaded rods up to 12 meters or more to be driven safely
3Adaptability or versatility
If the drilling machine is held freestanding during operation, then flexibility of operation is maintained, but the threaded rods cannot be properly clamped and may be ejected when the machine is turned on
Solution Approach 1:
The coupling device acts as an intermediary that connects the drilling machine to the base plate in a fixed, secure manner. The coupling body attaches to the base plate through threaded holes, providing a stable mounting foundation. This eliminates the need for freestanding operation while maintaining adaptability, as the coupling device can be installed at different locations on the base plate structure
Solution Approach 2:
The coupling device is installed on the base plate before the threaded rods are driven. This preliminary installation creates a secure mounting structure that prevents improper clamping and rod ejection when the drilling machine is activated. The reception space is prepared in advance to properly receive and secure the threaded rod
