Drilling Drive Track Assembly Mast Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chain drive systems for drilling rigs are uneconomical due to the time-consuming and costly process of attaching the fixed chain section to the mast, requiring manual alignment and welding of L-shaped brackets.
Innovation Solution
A drilling drive system with a mast, a bar, and a plurality of rungs welded to the bar, where a drive sprocket with teeth engages the rungs and a floating chain, allowing direct coupling to the mast without additional brackets, reducing the need for manual alignment and welding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If L-shaped brackets are manually welded to attach the fixed chain section to the mast, then the chain drive system can be assembled, but the setup process becomes time-consuming and costly
Solution Approach 1:
The patent combines the bar and rungs into a single integrated track assembly component that attaches directly to the mast as one unit, eliminating the need for separate L-shaped brackets. This merging of components simplifies the attachment process and reduces setup time while maintaining structural integrity.
Solution Approach 2:
The invention extracts and eliminates the L-shaped brackets from the assembly process entirely. By designing the track assembly with a bar that has rungs extending from it, the system removes the intermediate bracket component that was previously necessary for attachment, directly addressing the time and cost inefficiencies.
2Reliability
If L-shaped brackets are manually aligned and welded to the chain and mast, then the chain section can be securely attached, but the process requires high monetary and material costs
Solution Approach 1:
The track assembly merges the attachment function directly into the bar structure itself, which attaches to the mast and has rungs extending from it. This eliminates the need for separate brackets while maintaining secure attachment, thereby reducing device complexity without compromising reliability.
Solution Approach 2:
Instead of attaching brackets to the chain and then to the mast, the invention inverts the approach by having the bar with rungs attach directly to the mast as a unified structure. This reversal of the attachment sequence simplifies the overall assembly process and reduces the number of components involved.
3Manufacturing precision
If individual brackets are aligned with each side of the chain before welding, then proper alignment is achieved, but the setup process becomes time-consuming
Solution Approach 1:
The bar with rungs is designed as a single integrated component where the rungs are pre-positioned relative to the bar. This merging eliminates the need for individual alignment of separate brackets with each side of the chain, thereby maintaining manufacturing precision while significantly improving setup efficiency.
