A double-drum friction winch for retractable and towed submarine cable embedding machine

Abstract

The invention belongs to the field of cable laying ship submarine cable burying equipment and particularly relates to a take-up, pay-off and towing double-drum friction winch for a cable laying machine. The take-up, pay-off and towing double-drum friction winch for the cable laying machine comprises two cable towing drums, a mounting support base, a hydraulic motor, speed reducers, a rope guide sheave and a hydraulic control unit. A side plate is arranged on both sides of the mounting support base respectively. The cable towing drums are arranged in parallel and both ends of each of the cable towing drums are perpendicularly mounted on the side plates on both sides of the mounting support base and connected to the hydraulic motor through the speed reducers respectively. The cable towing speed reducers arranged on the same side of the mounting support base are connected through a connecting plate. The hydraulic control unit is mounted on the connecting plate. The rope guide sheave is mounted on the side edge close to a cable winch, of the side plates of the mounting support base. One end of a steel wire rope is connected to the cable laying machine and the other end is wound on the two cable towing drums and extends to be connected to the cable winch. The take-up, pay-off and towing double-drum friction winch for the cable laying machine provides traction and reduces the tension of the steel wire rope, thereby meeting the requirements of high load bearing and load variation.

Description

technical field [0001] The invention belongs to the field of auxiliary equipment for laying submarine cables for cable-laying ships, in particular to a double-drum friction winch for a retractable and towed submarine cable laying machine. Background technique [0002] When the cable laying ship carries out the submarine cable burying operation, the retraction and towing construction of the burying machine is usually completed by the winch. This kind of winch has its particularity in actual use. On the one hand, the working conditions of the winch are various, and it is necessary to operate the winch in combination with different working conditions to meet the corresponding operation requirements, which requires the winch itself to have multiple working modes; on the other hand On the one hand, the load at the end of the wire rope on the winch varies greatly, and the maximum load value is high, especially when pulling the embedding machine for trenching operations. The tradi...

Problems solved by technology

The traditional single-drum winch generally requires multi-layer winding. Due to the large change in the load at the end of the wire rope, it is very difficult to ensure that the wire rope is neatly arranged on the drum. It reduces the work efficiency, and causes friction and extrusion between the wire ropes, and even rope biting will shorten the service life of the wire ropes
