Problems solved by technology

These accidents involve the structural design of the winch and the submarine cable laying technology. Once the structural defects of the winch and the incorrect cable storage method are ignored, the entire submarine cable may be scrapped, and the repair or replacement cost will be as high as millions of dollars.

Embodiment Construction

[0018] Each component in this embodiment is described one by one below:

[0019] Such as Figure 1 to Figure 3 A detachable deep-sea cable winding winch is shown, including a winch body 1, the hub of the winch body 1 is covered with a detachable iron sheet 2 with grooves, and the tapered flange of the winch body 1 The inner side is covered with a detachable stepped iron plate 3, the tapered flange is a shell structure, and the tapered flange and the main shaft 4 are fixed by a trapezoidal spoke plate 5.

[0020] winch body such as figure 1 Shown, including smooth cylindrical flange, tapered flange. The flange is a thin-walled structure of the shell, which is funnel-shaped, supported by the trapezoidal web 5 and fixed with the central spindle. The number of 5 spokes at the flange on each side is not less than 8 spokes, which are symmetrically distributed and welded between the flange and the main shaft. The combination of the tapered flange and the web plate 5 can enhance t...

Abstract

The invention discloses a detachable deep submarine cable rolling winch which comprises a winch body. A hub of the winch body is covered with a detachable iron sheet with grooves. The inner sides of conic flanges of the winch body are covered with detachable stepped iron plates. The conic flanges are each of a shell structure and fixed to a spindle through trapezoidal wheel disks. Steps on each layer of the iron plates are matched with the grooves in the iron sheet and provided with grooves. Compared with a traditional cable storage winch, a cable can be prevented from laterally sliding in the axial direction of the hub through small traction tension, the cable layer squashing probability is greatly reduced in the submarine cable unrolling process when the cable is in transition from the bottom layer to the upper layer, the lateral anti-deformation capacity of the flanges is improved through the support of the wheel disks, the iron sheet on the hub and the flanges can be replaced according to different sea condition requirements and design of submarine cable technical parameters, the reuse rate of the winch is increased, and the detachable deep submarine cable rolling winch can meet the requirements for long cable arrangement and hoisting.

Description

technical field [0001] The invention belongs to the technical field of seabed resource development, and in particular relates to a deep sea cable winding winch for storage, transportation and construction deployment. Background technique [0002] At present, the operation scope of marine engineering equipment has expanded from shallow water to deep water and ultra-deep water, and the products have developed from fixed platforms to floating water facilities and underwater production systems. The characteristics of deep water operations are very obvious. Deepwater operations are faced with three major challenges, namely retractable winch system, dynamic response to the marine environment, and positioning and control technology. [0003] Marine retractable winch system includes winch, coiled steel wire rope or submarine cable, heave compensation device, support frame and auxiliary equipment. As an important equipment for offshore scientific research and construction, the r...
