Solution Overview
Problem
Current rock drilling rigs require complex measuring and positioning systems to accurately position the drilling unit, making the process cumbersome and operator-dependent, especially when shifting between drilling positions in mines and other worksites.
Innovation Solution
A rock drilling rig equipped with a detection device aligned in the direction of gravity to detect reference lines, allowing for simplified positioning by determining the current direction and horizontal distance of the drilling unit relative to the reference line, eliminating the need for external measuring devices and reducing the complexity of the positioning process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex measuring and positioning systems are used to accurately position the rock drilling unit, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The patent extracts the essential positioning function from complex external measuring systems and implements it through a simple detection device aligned with gravity direction. The detection device only needs to detect the reference line formed by pre-drilled holes, eliminating the need for complex external measuring equipment while maintaining positioning accuracy.
Solution Approach 2:
The system uses the pre-drilled holes themselves as the reference for positioning subsequent holes. The detection device on the rig detects the reference line formed by previously drilled holes, allowing the rig to self-position without external measuring equipment. This self-referencing approach simplifies the positioning system while maintaining precision.
2Measurement precision
If external measuring devices are used to determine position and direction of reference line, then measurement accuracy is improved, but device complexity increases
Solution Approach 1:
The patent removes external measuring devices from the system and replaces them with a detection device integrated into the rig that aligns with gravity. This detection device directly detects the reference line formed by pre-drilled holes, achieving accurate reference line detection without complex external equipment.
Solution Approach 2:
The detection device acts as an intermediary between the reference line (pre-drilled holes) and the positioning system. By aligning the detection device with gravity direction, it directly detects the reference line's position and orientation, serving as a simple yet effective mediator that eliminates the need for complex external measuring devices.
3Measurement precision
If separate reference markings are made to the worksite, then positioning accuracy is improved, but loss of time increases
Solution Approach 1:
The patent uses pre-drilled holes as reference points before the positioning operation begins. The reference line is already formed by previously drilled holes, eliminating the need for separate reference marking operations. This preliminary action of creating reference holes during normal drilling operations saves time while maintaining positioning accuracy.
Solution Approach 2:
The pre-drilled holes serve dual purposes: they are both the actual drilling results (production function) and the reference markers for positioning (measurement function). This multi-functionality eliminates the need for separate reference markings, as the drilling holes themselves provide the reference information needed for accurate positioning of subsequent holes.

AI summary
The invention relates to a rock drilling rig and a method of positioning a rock drilling unit. The rock drilling rig (5) is provided with a detection device (4) for detecting a reference line (RL), such as a previously drilled drill hole fan (1). The detection device is positioned in the direction of gravity (G). The position and direction of the detected reference line are utilized when positioning a drilling unit to a new drilling position at a predetermined horizontal reference distance (RD) from the reference line.
