Tilting Slide Mechanism for Compact Earth Drilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing earth drilling devices face difficulties in handling and connecting drill string sections due to their compact design, which restricts the length of the drill string sections and makes handling challenging, especially in confined spaces like trenches.
Innovation Solution
The introduction of a tilting device that allows the slide to incline relative to the feed axis, enabling better access and simplifying the handling of drill string sections by allowing them to be inserted and connected from the side, thus eliminating length restrictions and improving maneuverability within small trenches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a compact frame with slide is used for advancing drill string sections, then the device structure is compact, but handling of drill string sections becomes difficult and the length of drill string sections is restricted
Solution Approach 1:
The slide is made tiltable relative to the feed axis through a tilting device, allowing it to change its orientation dynamically. This enables the slide to be inclined at an angle α (e.g., 5-15 degrees) to facilitate lateral access and handling of drill string sections, while maintaining a compact frame structure. The dynamic adjustment of slide orientation resolves the contradiction between compactness and ease of operation.
2Length of stationary object
If the frame size and slide movement path are reduced, then the device becomes more compact, but the maximum size of drill string sections is restricted
Solution Approach 1:
The tilting device introduces a new dimension of movement by allowing the slide to incline at an angle α relative to the feed axis. This lateral inclination creates additional space for inserting and handling longer drill string sections from the side, effectively increasing the usable length capacity without expanding the overall frame footprint. The dimensional change in slide orientation enables longer drill string sections to be accommodated within a compact frame.
3Stability of the object's composition
If the slide is kept stable and linearly guided in the frame, then guidance precision is maintained, but access to the slide from above is limited
Solution Approach 1:
The tilting device enables the slide to dynamically adjust its orientation by inclining at an angle α to the feed axis. This dynamic tilting action opens up lateral access paths from above and the side, allowing operators to insert and handle drill string sections more easily. The slide maintains stability during operation when needed, while gaining improved accessibility during loading and handling operations.

AI summary
An earth drilling device includes a frame and a slide which is movable forward in the feed direction and backwards away from the feed direction. The frame includes a tilting device which causes the slide to incline relative to the frame and the feed axis when the slide is moved backward to the feed direction. An additional drill section may be inserted into the slide when it is inclined, then the slide may be moved forward in the feed direction to feed the additional drill section into the soil. A method for moving a drill section includes moving a slide opposite a feed direction in a frame. A tilting device causes the slide to incline relative to the frame and the feed direction, and an additional drill section is introduced into the slide. Then the slide is moved in the feed direction, feeding the additional drill section into the soil.
