Slope Compensation for Rotary Drill Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rotary drill machines face challenges in positioning on sloped surfaces, leading to significant movement of the drill bit away from its desired location, especially when operating autonomously, making repositioning difficult and impractical.
Innovation Solution
A system comprising a leveling system, position sensor, inclination sensor, and controller that determines dynamic offset compensation to align the rotary drill mechanism with the desired drill hole location by accessing machine characteristics, position signals, and slope signals, generating drive and leveling commands to adjust the machine's position and orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the leveling system is actuated to position the platform at the desired orientation, then the platform and drill bit achieve the correct orientation for drilling, but the drill bit location shifts away from the desired position on sloped surfaces
Solution Approach 1:
The system calculates and applies a dynamic offset compensation to the autonomous positioning before actuating the leveling system. This preliminary adjustment ensures that when the platform is leveled, the drill bit will be positioned at the correct location on sloped surfaces, eliminating the need for repositioning after leveling.
Solution Approach 2:
The system uses sensors to detect the actual position of the drill bit and the slope of the work surface, then feeds this information back to the controller. The controller continuously adjusts the dynamic offset compensation based on this feedback, maintaining accurate drill bit positioning even as conditions change during operation.
2Productivity
If the rotary drill machine is moved autonomously to the desired location, then positioning efficiency is improved, but repositioning becomes difficult when the drill bit location shifts after leveling
Solution Approach 1:
The system calculates the dynamic offset compensation in advance based on the detected slope and machine characteristics, and applies this compensation to the autonomous positioning target location before the machine arrives. This ensures that when the machine positions autonomously and then levels, the drill bit is already at the correct location, eliminating the need for difficult repositioning operations on sloped surfaces.
3Manufacturing precision
If the drill bit is repositioned after leveling to compensate for location shift, then location accuracy is improved, but operation time and complexity increase
Solution Approach 1:
The system performs the offset compensation in advance by adjusting the autonomous positioning target location based on detected slope conditions and machine characteristics. This eliminates the need for time-consuming repositioning operations after leveling, as the drill bit is already positioned correctly when the platform is leveled.
Solution Approach 2:
The system uses the machine's own sensors and control systems to automatically detect slope conditions, calculate the required offset compensation, and adjust the positioning target. This self-service capability eliminates the need for manual repositioning operations, saving time and reducing operational complexity.

AI summary
A system for compensating for a slope of a work surface while drilling holes in the work surface includes a leveling system, a rotary drill mechanism, a position sensor, an inclination sensor, and controller. The controller is configured to access coordinates of a desired map drill hole, determine current coordinates of a machine reference, and determine a current slope of the machine. A dynamic offset compensation is determined to compensate for movement of the rotary drill mechanism by the leveling system from a first position offset from the desired map drill hole to a second position aligned with the desired map drill hole, with the dynamic offset compensation being based upon the characteristics and the current slope of the machine. Upon the rotary drill mechanism being aligned with the first position, generating a leveling command to move the machine so that the rotary drill mechanism is aligned with the desired map drill hole.
