Cable Laying Apparatus Axial Direction Change
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable laying methods using radial direction cable drums occupy excessive road space, limiting the ability to transport large-scale and long-span ultra-high-voltage cables due to height restrictions when trying to maintain road width.
Innovation Solution
A cable laying apparatus that changes the cable direction from radial to axial, utilizing a frame unit with adjustable width and height to accommodate larger cable drums, featuring a traverse part to alter the cable withdrawal direction and a curvature guide for smooth cable laying, minimizing road occupancy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the cable drum width is increased to transport large-scale and long-span cables, then the cable capacity is improved, but the road occupancy space increases causing traffic problems
Solution Approach 1:
The patent changes the cable laying direction from radial (width-wise) to axial (length-wise) of the cable drum. This dimensional change allows the cable drum to be oriented longitudinally on the transport vehicle, reducing the width occupied on the road while maintaining the ability to lay large-capacity cables. The traverse part of the frame unit enables the cable to be redirected from radial withdrawal to axial laying direction.
2Quantity of substance
If the cable drum height is increased to achieve large-scale cables, then the cable capacity is improved, but the height is limited to 4-5 meters due to bridge and overpass restrictions
Solution Approach 1:
Instead of increasing cable drum height vertically (which is constrained by bridges and overpasses to 4-5 meters), the patent utilizes the axial dimension of the cable drum. By laying cables in the axial direction rather than radial direction, the system can accommodate larger cable capacities without increasing the height beyond road clearance limits.
3Quantity of substance
If the cable drum width is increased to satisfy user demand for large-scale cables, then the cable capacity is improved, but many road lanes are occupied during laying causing traffic restrictions
Solution Approach 1:
The patent resolves the traffic flow problem by changing the cable laying orientation from radial to axial direction. This allows the cable drum to be positioned with its length along the road direction rather than across it, minimizing the number of road lanes occupied during the laying operation and reducing traffic restrictions.

AI summary
Provided is a cable laying method using a cable laying apparatus capable of changing a direction of a cable, the cable laying method including: (A) installing a frame unit; (B) arranging a trailer bogie loaded with a cable drum inside the frame unit without additional loading work; (C) rotating the cable drum, which is loaded in the trailer bogie, by an under roller part; (D) changing a withdrawal direction of a cable unwound from the cable drum by a traverse part of the frame unit; (E) supplying the cable, the withdrawal direction of which is changed by the traverse part, to a cable unwinding part located at the rear of the traverse part; and (F) supplying the cable passing through the cable unwinding part to a required place through a curvature guide part located at the rear of the cable unwinding part, wherein the traverse part is configured to change a direction of the cable withdrawn in a radial direction of the cable drum to an axial direction of the cable drum.
