Wire rope anti-twist guide

Abstract

The invention discloses a wire rope anti-twist guiding device, which comprises a support seat installed on the deck of a ship, a guide unit arranged on the support seat and suspended above the water surface; the guide unit includes a vertically arranged guide support frame, At least one first roller in the frame; a guide channel for the wire rope of the crane is formed in the guide support frame, the guide channel is located on the first roller side and runs through the upper and lower ends of the guide support frame; one side of the guide support frame The sides are open and communicated with the guide channel to form an opening for the steel wire rope to enter and exit the guide channel. The wire rope anti-twisting guide device of the present invention is suitable for the installation and operation of large structures in deep water, and effectively solves the problem of twisting when installing large deep water structures in the double-strand steel wire rope mode of the existing ship resource crane; it enhances the offshore construction capacity of the existing ship resources , to enhance the competitiveness in the field of deep-water large-scale structure installation; simple 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
