Horizontal Drilling Rod Receiver Mandrel Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional horizontal drilling devices are limited by the short length of rod assembly sections due to the coaxial orientation of the changer motor, requiring frequent changes and increasing time consumption for drilling projects with defined bore lengths.
Innovation Solution
The rod assembly receiver is configured as a receiving mandrel to minimize its space requirements, allowing longer rod assembly sections and enabling faster attachment and release, with a pivotable design for efficient transport and attachment of sections, and integrated drilling fluid supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the changer motor is coaxially oriented with the drill rod assembly, then the device structure is compact, but the rod assembly section length is limited and requires frequent changes
Solution Approach 1:
The rod assembly receiver is designed to move between a first position (coaxial with the drill rod assembly for drilling operations) and a second position (perpendicular to the drill rod assembly for attachment operations). This spatial repositioning in a different dimension allows the receiver to accommodate longer rod assembly sections while maintaining compact device structure.
2Device complexity
If shorter rod assembly sections are used, then the device can be compact, but the frequency of section changes increases and time consumption increases
Solution Approach 1:
The rod assembly receiver is designed as a movable component that can dynamically reposition between two operational states: a first position during drilling and a second position during section attachment. This dynamic capability allows the system to use longer rod sections without compromising device compactness, thereby reducing the frequency of section changes and improving drilling efficiency.
3Length of moving object
If the rod assembly receiver is repositioned to a perpendicular position, then longer rod assembly sections can be attached, but the device requires additional movement mechanisms
Solution Approach 1:
The rod assembly receiver serves multiple functions: it holds rod assembly sections during attachment operations, positions them for connection to the drill rod assembly, and facilitates their integration into the drilling system. This multi-functionality reduces the need for separate specialized mechanisms, balancing the added complexity of repositioning with operational versatility.
