Broken Pipe Extractor With Hook Needle for Pipe Joint Reuse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Broken pipes within pipe joints are difficult to extract, leading to the scrapping of entire joints due to aging, especially when the broken pipe is embedded within the joint and hard to access.
Innovation Solution
A broken pipe extractor comprising a pipe body, blocking blocks, and a hook needle assembly that inserts through a blocking block to hook and remove the broken pipe from the joint, allowing for adjustable positioning and force application to facilitate extraction from joints of varying diameters and lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional extraction methods are used for broken pipes in pipe joints, then the extraction process becomes extremely difficult or impossible, but the entire pipe joint must be scrapped
Solution Approach 1:
The extraction tool is divided into multiple functional segments: a pushing component for initial engagement, a hook component for securing the broken pipe, and a pulling component for extraction. This segmentation allows each component to perform its specific function efficiently, enabling the recovery of broken pipes without scrapping the entire pipe joint.
Solution Approach 2:
The invention directly addresses the extraction of broken pipes from pipe joints by providing a specialized tool that can reach into the joint, engage the broken pipe, and pull it out. This extraction principle transforms the previously impossible task of removing embedded broken pipes into a feasible operation, thereby preventing joint scrapping.
2Adaptability or versatility
If a fixed-size extraction tool is used, then it can only handle pipe joints of specific dimensions, but it cannot accommodate joints of varying diameters and lengths
Solution Approach 1:
The extraction tool incorporates dynamic, adjustable components including an extendable pushing rod with adjustable length, and a hook component with adjustable arm length. These dynamic features allow the tool to adapt to pipe joints of various diameters and lengths without requiring multiple specialized tools, while maintaining reasonable structural complexity through straightforward adjustment mechanisms.
Solution Approach 2:
The extraction tool is designed as a universal device that can handle multiple sizes and types of pipe joints through its adjustable components. The pushing rod can be extended or retracted, and the hook arm length can be adjusted, allowing a single tool to perform extraction operations across a range of joint dimensions, thereby achieving multi-functionality.
3Ease of operation
If the broken pipe is deeply embedded in the joint, then it becomes inaccessible to traditional tools, but advanced extraction tools can reach and retrieve it
Solution Approach 1:
The extraction tool addresses deep embedding by extending the pushing rod in the axial dimension to reach broken pipes that are deeply embedded within the joint. This dimensional extension allows the tool to access previously unreachable locations without requiring complex lateral or rotational mechanisms, maintaining operational simplicity while achieving deep access.

AI summary
A broken pipe extractor for removing a broken pipe from a pipe joint includes a hollow pipe body, a first blocking block, a second blocking block, and a hook needle assembly. The first blocking block is located in the pipe body for fixing one end of the pipe joint. The first blocking block defines a through hole. A diameter of the through hole is greater than or equal to an inner diameter of the pipe joint. The second blocking block is movably fixed to one end of the pipe body for fixing another end of the pipe joint. The hook needle assembly is configured to be inserted through the through hole of the first blocking block and extend to the broken pipe to remove the broken pipe.
