Wire Stringing Angle Clamp for Messenger Wire Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of messenger wires in overhead transmission and distribution systems is costly and inefficient due to the need for multiple temporary and permanent retention devices, which increases labor costs and poses safety risks during the tensioned transfer process.
Innovation Solution
A stringing angle clamp device with a pulley wheel rotatable about an axle, connected guide arms, and wire clamping structures that allows for the direct installation and permanent retention of messenger wires on utility poles, eliminating the need for multiple devices and reducing the risk of accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple temporary and permanent retention devices are used for messenger wire installation, then the wire can be securely installed and retained, but the device complexity and labor costs increase significantly
Solution Approach 1:
The patent combines multiple separate devices (temporary stringing device and permanent retention device) into a single integrated angle clamp assembly. The angle clamp includes both the stringing function with a pulley wheel and the permanent retention function with a U-bolt clamping mechanism, eliminating the need to exchange between multiple devices during installation.
Solution Approach 2:
The angle clamp device performs multiple functions: it acts as both a temporary stringing device during installation and a permanent retention device after installation. The single device can string the messenger wire through its pulley wheel and then permanently secure it using the U-bolt clamping mechanism, serving dual purposes that previously required separate devices.
2Reliability
If multiple installation devices are used and exchanged during installation, then the messenger wire can be properly installed, but the installation time and labor costs increase
Solution Approach 1:
The patent combines multiple separate devices (temporary stringing device and permanent retention device) into a single integrated angle clamp assembly. The angle clamp includes both the stringing function with a pulley wheel and the permanent retention function with a U-bolt clamping mechanism, eliminating the need to exchange between multiple devices during installation.
Solution Approach 2:
The angle clamp is pre-configured with both the stringing mechanism (pulley wheel) and the permanent retention mechanism (U-bolt clamping structure) before installation begins. This preliminary configuration allows the installer to perform both stringing and permanent retention in sequence without needing to switch devices, significantly reducing installation time.
3Reliability
If temporary stringing devices are exchanged for permanent retention devices, then the messenger wire can be permanently secured, but safety risks increase during the tensioned transfer process
Solution Approach 1:
The patent combines multiple separate devices (temporary stringing device and permanent retention device) into a single integrated angle clamp assembly. The angle clamp includes both the stringing function with a pulley wheel and the permanent retention function with a U-bolt clamping mechanism, eliminating the need to exchange between multiple devices during installation.
4Reliability
If numerous different installation devices are used, then the messenger wire can be installed with proper tensioning and positioning, but the overall installation cost increases
