Rotating Cable Cutting Unit for Continuous Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cable recovery machines for overhead lines face inefficiencies and interruptions due to the need to handle multiple conductors and joints, requiring complex and cumbersome cutting processes, which hinder continuous and rapid cable replacement and disposal.
Innovation Solution
A cable recovery machine equipped with a traction module and a cutting module featuring a rotating cutting unit with a cutting blade, capable of continuous and uninterrupted cutting of cables regardless of composition or diameter, using a system of synchronized traction and idle wheels and conveyor belts for efficient cable alignment and discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional cutting module with translating cutters is used, then the cable can be cut into sections, but the cutting process becomes complex, cumbersome and inefficient, causing interruptions
Solution Approach 1:
Instead of moving the cutters horizontally to cut the cable (traditional approach), the patent inverts the approach by rotating a cutting unit vertically around the cable. The cutting unit with blade(s) rotates around the cable's longitudinal axis, cutting through the cable in its stationary position, thereby simplifying the mechanism and eliminating the need for complex translating cutter systems
Solution Approach 2:
The cutting unit is designed to rotate dynamically around the cable rather than using static translating cutters. This dynamic rotation allows the cutting blade to continuously engage the cable at different positions, enabling efficient cutting without the need for complex mechanical translation systems, thus improving productivity while reducing device complexity
2Ease of operation
If the winch machine stops to handle joints, then the cutting process can be completed, but countless interruptions occur during the reconductoring operation
Solution Approach 1:
The rotating cutting unit operates continuously as the cable passes through, cutting joints and cable sections without requiring the winch machine to stop. The continuous rotation of the cutting unit ensures that joints are cut and removed seamlessly during the reconductoring operation, eliminating countless interruptions and maintaining continuous productive action
3Adaptability or versatility
If multiple reel-holding trestles are used to house individual reels, then each conductor can be managed separately, but the size of the winch and brake stations increases proportionally
Solution Approach 1:
The rotating cutting unit serves multiple functions: it cuts all types of cables and joints regardless of diameter or material composition, and it operates continuously for all conductors. This universal cutting mechanism eliminates the need for multiple specialized cutting systems for different conductor types, thereby reducing the overall station size while maintaining adaptability for handling multiple conductors

AI summary
A cable recovery machine, having at least one traction module configured to hold and draw at least one cable, in particular of a cable laying plant, and at least one cutting module located downstream of the traction module and able to receive the cable that is introduced into the cutting module in a direction of feed (X1); the cutting module having at least one cutting unit provided with at least one cutting blade and integral with a shaft made to rotate by corresponding drive means, so that by rotating the shaft, the cutting unit is made to rotate and cuts the cable when the latter enters the cutting module in the direction of feed (X1).
