Track-Mounted Drill Rig Alignment Using Turning Trajectory Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in automatically controlling the alignment of a drill bit in a track-mounted drill rig with a target position, especially when drilling inclined holes, which can result in misalignment and inefficiencies.
Innovation Solution
An apparatus and method for controlling a track-mounted drill rig that determines a target position for the drill bit, calculates a turning trajectory for the aiming point of the drill bit, monitors the alignment of this trajectory with the target position, and adjusts the rig's movement to align the aiming point with the target position based on coincidence detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic control of drill rig movement is implemented, then drilling efficiency is improved, but alignment precision with target position deteriorates
Solution Approach 1:
The system continuously monitors the position of the aiming point relative to the target position during drill rig movement and automatically adjusts the movement to maintain alignment. This closed-loop feedback mechanism ensures that automated operation does not compromise precision, resolving the contradiction between improved productivity and maintained alignment precision.
2Loss of time
If the drill rig approaches the target position directly, then the approach time is reduced, but the alignment accuracy of the aiming point with the target position deteriorates
Solution Approach 1:
The system pre-calculates the turning trajectory of the aiming point before the drill rig approaches the target position. By determining the trajectory in advance and planning the approach path accordingly, the system enables the drill rig to move efficiently while ensuring the aiming point will coincide with the target position, thus reducing approach time without sacrificing alignment accuracy.
3Manufacturing precision
If the drill rig turns to align the aiming point with the target position, then alignment precision is improved, but the time required for positioning increases
Solution Approach 1:
The system dynamically adjusts the turning trajectory based on real-time monitoring of the aiming point position relative to the target. Rather than following a fixed turning path, the system adapts the trajectory during movement to optimize both the speed of positioning and the final alignment precision, thereby reducing positioning time while maintaining accuracy.

AI summary
An apparatus includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: determine a target position for a drill bit of the track-mounted drill rig; determine a turning trajectory of an aiming point of the drill bit; monitor position of the turning trajectory of the aiming point of the drill bit with respect to the target position of the drill bit during approach of the track-mounted drill rig to the target position; and cause turning of the track-mounted drill rig to align the aiming point of the drill bit with the target position of the drill bit based on determining that the turning trajectory of the aiming point of the drill bit substantially coincides with the target position of the drill bit.
