Description

Technical Field

[0001] This utility model relates to the field of roller cable guides, specifically an adjustable cable guide. Background Technology

[0002] During ship berthing and mooring operations, marine roller guides are crucial equipment for guiding and restricting the direction of mooring lines, and their performance directly affects the service life of the lines and operational safety. Currently, traditional marine roller guides are mostly fixed structures, and the position and spacing of the guide rollers cannot be flexibly adjusted according to actual needs.

[0003] When the installation position or direction of the cable changes, existing cable guides, unable to adjust the guide restraint position, often require disassembly and reinstallation. This not only increases operation time and labor costs but may also affect the connection stability due to frequent disassembly. Furthermore, different ships or operating scenarios use cables of varying thicknesses, while traditional cable guides have a fixed guide roller spacing, making it difficult to adapt to various cable specifications and resulting in poor versatility. If the cable and guide roller spacing do not match, it can easily lead to cable deviation, accelerated wear, or even jamming during guidance, potentially causing cable breakage and other safety accidents. Therefore, developing a marine roller cable guide that can flexibly adjust the guide restraint position without disassembling the equipment, adapt to cables of different thicknesses, and provide stable locking is a key requirement to overcome the shortcomings of existing technologies.
