Pipe Gripping Tool with Dynamic Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gripping tools for pipes are inadequate as they require continuous force to grip, are not ergonomic, and cannot easily move pipes axially or rotationally, making them difficult to handle and transport, especially for large diameter pipes in confined spaces.
Innovation Solution
A tool with a base, a first handle portion, and a second handle portion that is pivotally secured, featuring a flexible fastener with provisions for maintaining tension, allowing for secure gripping and easy handling of elongated objects without constant force application, enabling axial movement and rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional pipe gripping tools are used, then the pipe can be gripped, but continuous force must be applied to the handgrip which causes operator fatigue and makes the tool awkward to use
Solution Approach 1:
The tool employs a dynamic locking mechanism where the jaw member can be locked in position using a locking lever and locking surface. This allows the tool to maintain a secure grip on the pipe without requiring continuous force application, as the locking mechanism holds the jaw in place. The dynamic nature of the locking/unlocking action enables reliable gripping while eliminating operator fatigue from continuous force application.
Solution Approach 2:
The tool features a self-locking mechanism where the jaw member automatically locks onto the pipe through the locking surface and locking lever engagement. Once the jaw is positioned on the pipe, the locking mechanism maintains the grip without requiring continuous manual force. The tool serves itself by maintaining the gripping force through the mechanical lock rather than requiring continuous operator input.
2Reliability
If conventional pipe gripping tools are used, then the pipe can be gripped, but the tool is bulky and awkward to use in difficult to access areas
Solution Approach 1:
The tool is divided into separate functional components: a handle portion, a jaw member, and a locking mechanism. The jaw member can be detached or repositioned independently, allowing the tool to be configured for different pipe sizes and access situations. This segmentation reduces the overall bulk when not in use and allows the tool to adapt to difficult-to-access areas while maintaining gripping capability.
Solution Approach 2:
The tool incorporates a movable jaw member that can be opened and closed through the locking lever mechanism. This dynamic component allows the tool to accommodate various pipe diameters without requiring a bulky overall structure. The jaw member can be quickly positioned and locked, providing grip capability in confined spaces without the need for large, fixed结构的 conventional tools.
3Reliability
If conventional pipe gripping tools are used, then the pipe can be held, but the tool cannot easily move the pipe axially or rotationally
Solution Approach 1:
The tool is designed to perform multiple functions: gripping the pipe securely through the locked jaw, moving the pipe axially along its length, and rotating the pipe about its longitudinal axis. The handle portion provides leverage for all these operations, while the locking mechanism maintains secure holding during each function. This multi-functionality allows a single tool to replace multiple conventional tools, providing both secure gripping and versatile movement capability.
Solution Approach 2:
The movable jaw member and locking lever create a dynamic system that can adapt to different operational modes. When the locking lever is engaged, the jaw maintains a secure grip for axial movement or rotation. When disengaged, the jaw can be repositioned to facilitate different types of pipe manipulation. This dynamic design enables the tool to provide both reliable securing and versatile movement capability as needed.
4Reliability
If conventional pipe gripping tools are used, then the pipe can be gripped, but the tool requires two people to join pipes effectively
Solution Approach 1:
The tool's dynamic locking mechanism allows a single operator to secure and manipulate pipe sections independently. The locking lever and locking surface enable one person to hold the pipe firmly during coupling operations, eliminating the need for a second person to assist with holding. The ergonomic handle design further enhances ease of operation for single-person use while maintaining reliable pipe holding capability.
