Title:
NOVEL UMBILICAL CABLE ANCHORING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2016/062122
Kind Code:
A1
Abstract:
An umbilical cable anchoring structure, comprising a base (1) fixed to a working platform. The base comprises a bearing platform and an inverted conical guide channel for an umbilical cable (6), the guide channel being welded to the bottom of the base. Pore passages (2) are arranged on the bearing platform in a surrounding mode, and the number of the pore passages (2) is identical to that of armored steel wires. The armored steel wires (3) stripped from the outer layer of the umbilical cable penetrate through the pore passages. Each pore passage has an embracing and fixing ring (4) and a puller bolt (5) connected thereto in a matching mode. The inner diameter of each embracing and fixing ring is of a horn-shaped structure from top to bottom, and a petal-shaped slot is formed in one end of each embracing and fixing ring. Compared with a slab or conical dual-bearing-platform anchoring structure used for a traditional undersea cable, the umbilical cable anchoring structure does not have fastening and bearing cover plates, and materials are saved; all the armored steel wires of the umbilical cable can play a role in the using process, the bearing capacity of the anchoring structure is increased, and reliability is improved; the armored steel wires are easy to operate and convenient to construct in the anchoring process.
