CABLE-DRIVEN FOLLOW-UP ROV WINCH APPLIED TO NON-POWERED POSITIONING MOTHER SHIP

摘要

A cable-driven follow-up ROV winch applied to a non-powered positioning mother ship, comprising a non-powered positioning mother ship (1), an A-type frame (2) and a winch retracting cable roller (6) disposed on the non-powered positioning mother ship (1), and an underwater robot (3), wherein the A-type frame (2) is rotatably connected to a pulley (4), the underwater robot (3) is connected to an umbilical cable (61), the umbilical cable (61) bypasses the pulley (4) to connect to the winch retracting cable roller (6), and the non-powered positioning mother ship (1) is also provided thereon with a positioning member (5) used for guiding the umbilical cable (61). The A-type frame (2) is provided with a connecting rod (21), the pulley (4) comprises a sliding portion (42) and a rotating portion (41), the sliding portion (42) is annular and slides on the connecting rod (21) along the direction of the connecting rod (21), the connecting rod (21) is opened thereon with a bar-shaped groove (22), a bump (44) protrudes from the sliding portion (42), and the rotating portion (41) is connected at an outer ring of the sliding portion (42) by means of the rotation of a bearing. By means of the pulley (4) being designed to slide freely on the A-type frame (2), the operating frequency of the underwater robot (3) due to the rotation of the ship may thus be reduced while reducing the risk of the underwater robot (3) being lost due to the umbilical cable (61) breaking.
