Three drum hydraulic cable winch

Abstract

The invention relates to a three-winding-drum hydraulic cable winch which comprises a base, a rotary pedestal mounted on the base, a hydraulic motor, a manual rotary device and winding drums. The two sides of the rotary base are separately provided with a left bracket and a right bracket. The winding drums are mounted between the left bracket and the right bracket through a spindle and mounted on the spindle. The hydraulic motor is mounted on the outer side of the left bracket and connected with the spindle. The manual rotary device is mounted on the outer side of the right bracket and connected with the rotary pedestal to drive the winding drums to rotate around the base. The rotary pedestal is provided with a three-way hydraulic rotary central connector. A hydraulic pipeline is connected with an oil port of the three-way hydraulic rotary central connector through the base, and the other oil port of the three-way hydraulic rotary central connector is connected with the hydraulic motor through a hydraulic pipeline. The hydraulic motor drives the winding drums to rotate so as to wind and unwind cables. The three-winding-drum hydraulic cable can save the ship space, adapt to simultaneous connection of different cables and be freely rotated to change the angle.

Description

Technical field [0001] The invention relates to a marine winch, in particular to a three-drum hydraulic cable winch for the shore power system of a ship and for the ship to supply power to other special ships. It belongs to the technical field of ship parts manufacturing. Background technique [0002] As a device that provides power, control cables and communication optical cables for large-scale mobile equipment, cable reels are widely used in port portal cranes, container cranes, ship loader, and tower crane equipment. The shore power system emerging nowadays requires the use of cable reels for power transmission from the shore grid to ships, and the use of cable reels for power supply from the ship to other special ships, but the existing cable reels are used for shore power The system and the power supply system for other special ships have the following problems: 1. The space of the ship is limited; 2. The structure that uses a large number of marine winches cannot be fully...

AI Technical Summary

Problems solved by technology

The shore power system emerging today, that is, the power transmission from the shore power grid to the ship requires the use of a cable reel, and the power supply from the ship to other special ships also requires the use of a cable reel, but the existing cable reel is applied to the shore power The system and other special ship power supply systems have the following problems: 1. The space of the ship is limited; 2. The structure that uses a large number of marine winches cannot be fully applied to various occasions of cable connection; 3. It requires many people to cooperate with the operation, which is laborious , cannot use the shore power system quickly and efficiently
