Auxiliary net lifting device for fishing boat net lifting machine

Abstract

The invention relates to the technical field of net lifting machines for fishing boats, and discloses an auxiliary net lifting device for the net lifting machine for fishing boats. One end of the wheel facing the frame is fixedly equipped with a rotating shaft, and the end of the rotating shaft is fixedly equipped with a bearing, and the outer wall of the bearing is fixedly installed with a fixed column, and the fixed column is fixedly installed at the edge of the outer wall of the turntable. When there is no debris on the line rope, the pressure wheel presses against the working rubber wheel to clamp the line rope. At this time, the pressure wheel rotates on the bearing through the rotating shaft, which not only increases the friction between the line rope and the working rubber wheel, but also It can assist the line rope to be retracted without idling and slipping of the working rubber wheel, which effectively reduces the loss of the line rope and saves the use cost. The utility model has the advantages of being suitable for wire ropes of different diameters and convenient for adjusting the position of the wire rope on the working rubber wheel.

Description

technical field [0001] The invention relates to the technical field of net hoisting machines for fishing boats, in particular to an auxiliary net hoisting device for net hoisting machines for fishing boats. Background technique [0002] The net lifting machine is a collective name for the machinery that lifts the net from the water to the ship, shore or ice by means of the friction between the power component and the net. It is widely used on various fishing boats, which can reduce the labor intensity of workers and speed up the lifting of the net. speed. In order to increase the frictional force between fishing gear such as outline ropes and the rubber wheel of the net lifting machine, people usually set pressure wheels around the working rubber wheel, as the Chinese patent announcement number is: the patent of CN201165321Y, which just discloses a fishing boat lifting The auxiliary net lifting device of the net machine solves the problems of high labor intensity, low work ...

AI Technical Summary

Problems solved by technology

[0004] 1. The structure of the above-mentioned pressure wheel is relatively complicated, and it is troublesome to maintain. The high pressure generated will easily cause the deformation of the line rope, accelerate the wear of the line rope, and shorten the service life. At the same time, when there are sundries on the line rope, the above pressure The wheel must be manually adjusted to allow debris to pass through, otherwise the pressure wheel will be damaged by a large impact, and the safety of manual operation is not ideal;

[0005] 2. The structure of the above pressure wheel is inconvenient to adjust the distance between the pressure wheel and the working rubber wheel, and cannot be applied to different diameters of the wire rope. If the pressure wheel and the working rubber wheel squeeze the wire rope too tightly, it will easily lead to deformation of the wire rope or frayed ropes;

[0006] 3. When the working rubber wheels of the above-mentioned net lifting machine are in use, the wear of the working rubber wheels by the rope is often concentrated in one area (if the rope wears out a dent on the working rubber wheels, then in the subsequent lifting of the net The rope will still easily follow the dent), so the working rubber wheel will be severely worn in a specific area after long-term use. Although other parts of the rubber wheel are still intact, they can no longer be used. Greatly shorten the service life of the rubber wheel
