Portable Bucking Frame With Adapter Plate For Power Tongs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bucking units for making and breaking tubular connections in oil and gas wells are heavy, large, and difficult to transport, and are often specific to certain power tongs, limiting their versatility and causing issues with tubular joint integrity due to the need for precise fit and positioning.
Innovation Solution
A portable bucking frame with adjustable backup jaws and feet for aligning pipes, and an adapter plate that allows for the mounting of various commercially available power tongs, enabling versatile and efficient pipe connection operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional bucking unit is used, then tubular connections can be made and broken, but the unit is heavy, large, and difficult to transport
Solution Approach 1:
The bucking unit is divided into separate components: a portable bucking frame and a power tong assembly. The frame can be easily transported and assembled at the work site, while the power tong is separately mounted on the frame during operation. This segmentation allows the frame to be lightweight and portable while still providing the necessary functional capabilities.
Solution Approach 2:
The heavy components of the traditional bucking unit (drive unit and backup unit) are extracted and replaced with a simplified frame structure that can be easily transported. The essential function of holding and positioning the tubular member is retained in the backup jaw assembly, while the driving function is provided by a separately mounted power tong.
2Adaptability or versatility
If a bucking frame is configured for a specific power tong, then the power tong can be securely mounted, but the frame cannot accommodate different power tong types from various manufacturers
Solution Approach 1:
The bucking frame is designed with a universal mounting structure that can accommodate different types of power tongs from various manufacturers. The frame includes multiple mounting points and adjustable components that can be configured to fit different power tong specifications, making the frame multi-functional and adaptable to various tools without requiring custom configurations.
3Reliability
If power tongs with specific mounting points are used, then the power tong can be properly attached, but different manufacturers have different mounting points that do not align
Solution Approach 1:
An adapter plate is introduced as an intermediary component between the bucking frame and the power tong. The adapter plate features multiple mounting hole configurations that can accommodate different power tong mounting patterns. This intermediary allows reliable attachment of power tongs from various manufacturers to the universal frame structure without requiring the frame itself to be customized for each power tong type.
4Manufacturing precision
If adjustable backup jaws are used, then pipes can be properly aligned and positioned, but the device becomes more complex
Solution Approach 1:
The backup jaws are designed to be adjustable and movable along the bucking frame, allowing dynamic positioning to accommodate different pipe sizes and alignment requirements. The jaws can be moved to the appropriate position and secured, providing precise control over pipe alignment without requiring a completely complex redesign of the entire frame structure.
