Axially Adjustable Pipe Bunker for Deep Drilling Pillars
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drilling implements face limitations in usability and universality, particularly in varying the axial spacing of the pipe hopper relative to the carriage, which restricts deep drilling capabilities and efficient filling of drill holes with fill material.
Innovation Solution
The pipe hopper is axially adjustably mounted on the carriage, allowing for variable positioning and torque-proof coupling with the drill pipe, enabling increased axial travel and easy fill material access, with options for rotary and linear drive mechanisms and torque support systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pipe bunker is fixed on the carriage, then the structure is simple, but the axial spacing cannot be varied and axial travel is restricted
Solution Approach 1:
The pipe bunker is made axially adjustable relative to the carriage through a mounting structure that allows movement along the axial direction. The drive mechanism enables the pipe bunker to be positioned at different axial locations, transforming a static fixed mounting into a dynamic adjustable system that provides versatility while maintaining operational simplicity.
2Ease of operation
If the pipe bunker is positioned far from the carriage, then fill material accessibility is improved, but the axial travel during drilling is reduced
Solution Approach 1:
The axially adjustable mounting allows the pipe bunker to be dynamically repositioned. During drilling operations, the pipe bunker can be positioned closer to the carriage to maximize axial travel distance. During filling operations, it can be moved to a position that optimizes accessibility for fill material delivery, thus resolving the contradiction between accessibility and travel distance through temporal separation of optimization.
Solution Approach 2:
The pipe bunker can be pre-positioned to optimal locations before specific operations. Before drilling begins, the pipe bunker is positioned to allow maximum axial travel. Before filling operations, it is repositioned to optimize accessibility, ensuring that each operation starts with the most favorable configuration.
3Adaptability or versatility
If the pipe bunker is fixed relative to the drill pipe, then torque transmission is simple, but the pipe bunker cannot be independently positioned
Solution Approach 1:
The coupling system is segmented into two independent functional parts: a torque-proof coupling between the drill pipe and carriage that ensures reliable torque transmission, and a separate axial adjustment mechanism that allows independent positioning of the pipe bunker relative to the carriage. This segmentation allows each function to be optimized independently without compromising the other.
