Description

Technical Field

[0001] The utility model relates to the technical field of ship cable winder structures, in particular to a universal ship cable guide device. Background Art

In the existing cable winder structure, when the rope is retracted or released, the unfolded rope is directly guided by the roller. This makes it easy for the unfolded rope to scratch and shear the reeled rope on the roller when the angle between the unfolded rope direction and the tangent of the roller is large. At the least, the rope will be tangled and messy, and at the worst, the rope will be worn, damaged and even broken. Therefore, a cable guide structure on the cable winder that can achieve wide-range and multi-angle guidance adjustment of the rope is an important and indispensable structure to ensure the normal operation of the cable winder and protect the rope.
