Drilling and Bolting Device Feed Frame Guide System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drilling and bolting rigs face challenges in efficiently and accurately inserting drill elements into rock surfaces due to limitations in guide systems and fluid power actuation, which can result in reduced precision and increased operational complexity.
Innovation Solution
The drill device incorporates a base frame with fluid cylinders, a feed frame supported for movement along a feed axis, and a feed device with guide members and a flexible transmission system, allowing for precise movement and adjustment of a drill element into a rock surface using a combination of guide bars and fluid actuation, enabling efficient and accurate drilling and bolting operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional guide systems are used in drilling and bolting rigs, then the structure is simpler, but the precision of drill element insertion is reduced
Solution Approach 1:
The guide system is divided into multiple guide bars (first guide bar, second guide bar, third guide bar, fourth guide bar) that work together to provide precise guidance for the drill element. Each guide bar is positioned at specific locations and orientations to collectively achieve high precision insertion while maintaining manageable structural complexity
Solution Approach 2:
Guide members are introduced as intermediary elements between the feed device and the drill element. These guide members engage with both the feed device and the drill element, providing a mediating mechanism that ensures precise alignment and controlled movement during insertion
2Power
If fluid power actuation is used, then the power delivery is stronger, but the operational complexity increases
Solution Approach 1:
The feed device combines multiple functions into a single integrated unit: it incorporates the feed mechanism, the guide members, and the connection to the drill element. This merging reduces operational complexity by eliminating the need for separate control systems for each function while maintaining strong power delivery through fluid power actuation
Solution Approach 2:
The feed device is designed as a multi-functional unit that performs feeding, guiding, and positioning operations simultaneously. The guide bars serve multiple purposes: providing structural support, guiding the drill element, and defining the insertion path. This multi-functionality reduces overall system complexity

AI summary
A drill device includes a base frame, a feed frame supported for movement relative to the base frame, and a feed device for inserting a drill element into a rock surface. The base frame includes a pair of fluid cylinders. The feed frame extends along a feed axis and includes a plurality of guide bars aligned parallel to the feed axis. The feed device is supported for movement relative to the feed frame in a direction parallel to the feed axis. The feed device includes a first guide member and a second guide member. The first guide member engages a surface of at least one of the guide bars, and the second guide member engages another surface of at least one of the guide bars.
