Multi-Angle Drill Support Structure for Stable Inclined Boring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drilling devices for geotechnical engineering investigation are limited to vertical drilling, making them unsuitable for inclined drilling situations, which restricts their application range and stability.
Innovation Solution
A drilling device with a multi-angle positioning system, featuring a rotatable outer and middle supporting ring seats connected by shaft rods, locking mechanisms, and a buffering mechanism, allowing the drill pipe to rotate at any angle and maintain stability, enabling both inclined and vertical drilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the drill pipe is limited to vertical direction, then a stable drilling state is maintained, but the application range is reduced and inclined drilling cannot be performed
Solution Approach 1:
The patent transforms the static vertical drill pipe constraint into a dynamic multi-angle positioning system. The drill pipe is connected to the drill head through a universal joint that allows rotation and inclination adjustment, enabling the drill pipe to dynamically adapt to different drilling angles while maintaining stability through locking mechanisms during operation.
Solution Approach 2:
The patent segments the drilling system into independent functional modules: the drill head assembly with universal joint, the drill pipe, and the locking mechanism. This segmentation allows the drill head to independently adjust angles while the drill pipe maintains its structural integrity, resolving the contradiction between flexibility and stability.
2Adaptability or versatility
If a multi-angle positioning system with rotatable ring seats and shaft rods is added, then drilling angle versatility is improved, but device complexity increases
Solution Approach 1:
The patent employs a nested structure where the inner supporting ring seat is positioned within the middle supporting ring seat, which is in turn positioned within the outer supporting ring seat. Each ring seat contains a shaft rod that connects to the next level, creating a compact nested arrangement that reduces overall system complexity while achieving multi-angle positioning capability.
Solution Approach 2:
The universal joint at the connection between drill pipe and drill head serves multiple functions: it allows rotation in multiple directions, provides inclination adjustment, and maintains structural support. This multi-functionality reduces the need for separate mechanisms for each function, thereby reducing overall device complexity.
