Slide Hammer Guide Frame for Driving and Pulling Rebar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing post driving and pulling devices lack a mechanism to efficiently apply both continuous and intermittent forces for driving and pulling elongated building elements like solid rods and rebar, with prior art failing to provide a secure and efficient means to lock and engage such elements during these processes.
Innovation Solution
A building element driving and pulling device featuring an elongated guide frame with a drive stop and pull stop, a locking assembly, and a slide hammer that allows for manual sliding along a guide channel to apply both pressing and striking forces for driving and pulling building elements into and out of materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single tool is used to both drive and pull building elements, then device versatility is improved, but device complexity increases
Solution Approach 1:
The device integrates both driving and pulling functions into a single tool. The guide frame with guide channel accommodates building elements for both operations, the locking assembly can secure elements for driving or pulling, and the slide hammer can be positioned to deliver striking forces in either direction, making one device capable of performing multiple functions.
Solution Approach 2:
The device is divided into distinct functional modules: the guide frame structure, the locking assembly, and the slide hammer mechanism. Each module can independently perform its specific function while contributing to the overall versatility, allowing the device to handle both driving and pulling operations through coordinated action of these segmented components.
2Reliability
If a locking assembly is added to secure building elements, then reliability of operation is improved, but device complexity increases
Solution Approach 1:
The locking assembly acts as an intermediary mechanism between the guide frame and the building element. It provides a secure connection that enables reliable transfer of forces during both driving and pulling operations, ensuring that the building element remains properly positioned and secured throughout the operation without requiring overly complex integration methods.
3Ease of operation
If the slide hammer is made manually slidable along the guide channel, then ease of operation is improved, but force application efficiency decreases
Solution Approach 1:
The manual sliding motion of the slide hammer along the guide channel creates periodic action through the locking mechanism. As the slide hammer is moved back and forth, the locking assembly engages and disengages in a controlled manner, converting the manual sliding motion into effective periodic striking forces that maintain both ease of operation and force application efficiency.
Solution Approach 2:
The guide channel provides a continuous path for the slide hammer to move along, ensuring that the useful action of force application continues without interruption. The locking assembly maintains continuous engagement with the building element during the sliding motion, ensuring that every movement of the slide hammer contributes to effective force application throughout the entire operation.
