Top Drive Power Swivel Stabilization via Multi-Point Frame Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drilling technologies face challenges in efficiently and securely drilling through consolidated surfaces with existing power swivels, which are often unstable and disrupt the drilling site, necessitating a more secure and stable top drive power swivel assembly.
Innovation Solution
A top drive power swivel assembly is integrated with a travelling frame using multiple connectors, such as solid steel pins, to provide mechanical stabilization through upper and lower attachment points, allowing secure engagement and improved stability during drilling operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional power swivels are used without mating to the travelling frame, then the drilling operation can proceed, but the power swivel becomes unstable and causes disruption at the field site
Solution Approach 1:
The power swivel is merged with the travelling frame by providing attachment means on both components that mate together. The attachment means on the power swivel engages with corresponding attachment means on the travelling frame, creating a unified assembly that eliminates instability and field site disruption while maintaining drilling functionality.
2Reliability
If multiple connectors are used to attach the power swivel to the travelling frame, then secure engagement and stability are achieved, but the device complexity increases
Solution Approach 1:
The attachment system is segmented into discrete attachment means located at specific positions on both the power swivel and travelling frame. This segmentation allows for secure engagement through multiple connection points while maintaining modularity and avoiding excessive complexity by using standardized, repeatable attachment components rather than a monolithic complex structure.

AI summary
A top drive power swivel assembly for well drilling rigs having a travelling frame for moving along a drilling tower. The travelling frame has at least two lower and two upper travelling frame extensions. A housing has at least two upper and two lower housing extensions each with an opening. A first connector penetrates openings of upper travelling frame extensions and openings of an upper housing extensions engaging the travelling frame to the housing. A second connector penetrates openings of lower travelling frame extensions and openings of lower housing extensions to securely engage the travelling frame to the housing. A top drive power swivel mounts to the housing and the top drive power swivel receives power from hydraulic motors. Various sheave assemblies mounted to the travelling frame engage a hoisting means. Guide wheel assemblies disposed on the travelling frame engage the tubulars.
