Cable self-adapting adjusting device of winch for ship

Abstract

The invention relates to an auxiliary device of a winch for a ship, in particular to a cable self-adapting adjusting device of the winch for the ship, which comprises a rocker arm provided with a pulley on a pulley shaft at one end. The other end of the rocker arm is rotationally connected with and fixed on a rocker arm shaft on a bracket, the upper end of an extension spring is fixed in the middle of the rocker arm, the other end of the extension spring is fixed on the bracket at the lower part of a lower limit stop dog, the bracket is fixed on a ship deck which is 1-2m away from the winch for the ship, the pulley on the rocker arm is across connected to the cable between a winch guide wheel and a door-type rack pulley, the bracket for limiting the running interval of the rocker arm is respectively provided with an upper limit stop dog and a lower limit stop dog, and the distance between the upper limit stop dog and the lower limit stop dog is in the range of 1.5-2m. Obviously, the invention and the winch for the ship are used together to adapt to the automatic adjustment along with the degree of the tightness of the wire cable, so that a winch cable discharger normally discharges the cables and the continuity of oceanographic surveying data is ensured effectively.

Description

technical field [0001] The invention relates to an auxiliary device of a marine winch, in particular to a self-adaptive adjustment device for a marine winch cable. Background technique [0002] During marine surveys, the water depth often exceeds 1,000 meters, and the sea state reaches level 4 or above. In this sea area, when measuring, sampling or observing, the winch cable is sometimes tight and sometimes loose, and it is easy to cause the winch cable unloading device to lose its function and cannot normally unwind the cable. Or the steel cable is discounted or broken. At this time, the work can only be stopped, and the method of manually pulling the steel cable on the spot is used to remove hidden dangers. Obviously, it is not safe and reliable, and affects the smooth progress of marine surveys. Contents of the invention [0003] The purpose of the present invention is to provide a kind of self-adaptive adjustment device of the ship winch cable, to overcome the deficien...

Or the steel cable is discounted or broken. At this time, the work can only be stopped, and the method of manually pulling the steel cable on site to eliminate hidden dangers is obviously not safe and reliable, and it will also affect the smooth progress of marine surveys.
