Rotary untwisting rack with double cable reels

Abstract

The invention relates to a rotary untwisting rack with double cable reels. The rotary untwisting rack comprises a rotating mechanism, a cable bracket, an untwisting rack upright column and a rotary untwisting rack crossbeam. The rotary untwisting rack crossbeam is connected to the upper surface of the untwisting rack upright column by the rotating mechanism, the cable bracket is disposed on the rotary untwisting rack crossbeam, and the cable bracket at the front end of the rotary untwisting rack crossbeam rotates along a preset track via the rotating mechanism, can be fixed to upper sides of two cable storage rings respectively, collects cables from the two cable reels and guides the cables into an untwisting rack, so that continuous untwisting and laying construction can be carried out. Uninterrupted untwisting operation for stacking a single cable behind two cable carrying areas can be realized by rotation of the untwisting rack crossbeam, so that the single ultra-long submarine cable can be stored by the two cable reels, and can be subjected to normal untwisting and laying construction, and a series of problems that a cable is required to be cut into sections, and then cut sections of the cable are abutted, sealed and then are laid due to limitation of the traditional untwisting equipment are avoided.

Description

technical field [0001] The invention relates to a double-drum rotating untwisting device used for submarine light and cable laying. Background technique [0002] At present, with the increasing market demand and the improvement of submarine cable manufacturing technology, the length and weight of a single submarine cable continue to increase; limited by the maximum allowable lateral pressure of the submarine cable itself, a single cable storage ring will not be able to store all the submarine cables used in construction . Expansion of the cable coil or cable storage area has the disadvantage of high reconstruction cost on most submarine cable construction ships with a single cable coil layout, and there is basically no room for expansion if the hull structure is not changed; while the construction ship with a double cable coil layout adopts two In the case of storing a single cable at the same time, the existing facilities cannot be used to complete the loading and untwisti...

Problems solved by technology

[0002] At present, with the increasing market demand and the improvement of submarine cable manufacturing technology, the length and weight of a single submarine cable continue to increase; limited by the maximum allowable lateral pressure of the submarine cable itself, a single cable storage ring will not be able to store all the submarine cables used in construction

Expansion of the cable coil or cable storage area has the disadvantage of high reconstruction cost on most submarine cable construction ships with a single cable coil layout, and there is basically no room for expansion if the hull structure is not changed; while the construction ship with a double cable coil layout adopts two In the case of storing a single cable at the same time, using the existing facilities, it is impossible to complete the loading and untwisting operations of the cable, so that normal construction cannot be carried out.
