Spring Suspension Clip for Threaded Rod Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for positioning threaded rods during overhead rock grouting are inefficient, as they often require manual placement or use costly expandable heads that restrict grout flow and fail when holes are oversized.
Innovation Solution
A spring suspension clip with a helical body that clips over the threaded rod, allowing flexible suspension and adjustable positioning within a rock section, facilitating grout placement and setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual positioning methods are used to position threaded rods, then positioning can be achieved, but the process is time-consuming and labor-intensive
Solution Approach 1:
The spring suspension clip is designed to automatically grip and hold the threaded rod in position without requiring manual adjustment or additional fastening steps. The spring mechanism self-adjusts to secure the rod, eliminating the need for continuous human intervention and significantly reducing positioning time while maintaining secure holding.
2Reliability
If expandable heads are used to position threaded rods, then positioning is achieved, but the cost increases and grout flow is restricted
Solution Approach 1:
The spring suspension clip employs a flexible helical spring design that can deform and adapt to the threaded rod while maintaining a compact profile. This flexible structure provides reliable positioning without creating the bulky obstruction that expandable heads generate, allowing grout to flow freely past the positioning mechanism.
3Reliability
If expandable heads are used for positioning, then positioning is achieved, but the method fails when holes are oversized
Solution Approach 1:
The spring suspension clip utilizes a dynamic spring mechanism that can compress and expand to accommodate varying hole sizes and threaded rod positions. Unlike rigid expandable heads that fail when oversized, the spring clip adapts its grip strength and position dynamically, maintaining reliable positioning across a range of hole diameters and installation conditions.
4Reliability
If conventional positioning methods are used, then threaded rods can be positioned, but the device complexity and cost increase
Solution Approach 1:
The invention extracts only the essential positioning function from complex conventional systems. The spring suspension clip uses a simple helical spring mechanism combined with a clipping structure, eliminating unnecessary components found in expandable heads or manual positioning systems. This minimalistic design achieves reliable positioning with significantly reduced device complexity and lower cost.

AI summary
A spring suspension clip configured to suspend a threaded rod member comprises a helical body with an upper end and a lower end, and a clipping section defined as the helical body. Then the clipping section is configured to conform to a threaded section of the threaded rod member to flexibly suspend the by two outward extensions into a space which is drilled and positioned within a section of rock which is to be grouted.
