Steel wire rope anti-torsion guide device

Abstract

The invention discloses a steel wire rope anti-torsion guide device, which comprises a support seat installed on a deck of a ship and a guide unit arranged on the support seat and suspended above thewater surface. The guide unit comprises a guide support frame arranged vertically and at least one first roller arranged in the guide support frame. A guide channel through which the steel wire rope of a crane passes is formed in the guide support frame. The guide channel is located on one side of the first roller and penetrates the upper and lower ends of the guide support frame. One side of theguide support frame is opened and communicated with the guide channel to form an opening for the steel wire rope to enter and exit the guide channel. The steel wire rope anti-torsion guide device is suitable for deep-water installation operations of large structure objects, effectively solves a twisting problem of an existing ship resource crane double-strand steel wire rope mode when installing deep-water large structure objects, enhances existing ship resource offshore construction capabilities, enhances competitiveness in the field of deep-water large structure object installation, and hassimple structure, low prefabrication cost and high construction efficiency.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a wire rope anti-twist guiding device. Background technique [0002] Deepwater oil and gas development is becoming the main growth point of the world petroleum industry and the frontier of scientific and technological innovation. The recoverable scale of offshore oil and gas fields increases significantly with the increase of water depth. Globally, more than half of offshore oil and gas resources are distributed in waters deeper than 300 meters. The development of deep-water offshore oil and gas is inseparable from various underwater structures, which collect the produced oil, gas, water multi-phase or single-phase fluids, and return them to nearby underwater, surface or onshore supporting facilities , to realize the development of offshore oil and gas fields. [0003] Deepwater underwater structures are an important part of the underwater production system. Accordin...

AI Technical Summary

Problems solved by technology

The "twisting" of the wire rope will not only increase the wear and tear, but also increase the safety risk of hoisting operations

In order to ensure that large underwater structures can be safely and smoothly installed in deep water, it is necessary to design an auxiliary tool to solve the twisting problem of the double-strand wire rope of the crane
