Retractable towing winch of submarine cable embedding machine

Abstract

The invention belongs to the field of supporting device for submarine cable embedding of a cable laying ship, and particularly relates to a retractable towing winch of a submarine cable embedding machine. The retractable towing winch comprises a cable storage winch and a cable dragging winch, wherein the cable dragging winch drives a cable dragging reel to rotate through a cable dragging winch; the cable storage winch comprises a roper guider and a cable storage mechanism; the rope guider comprises a guide wheel, a guide wheel supporting bracket, a guide wheel supporting base and a guide wheel motor; a wire rope deflection detecting device and a wire rope length counting device are arranged on the guide wheel supporting bracket, wherein the wire rope deflection detecting device sends a signal to control the rotation of the rope guider motor, and further control the movement of the guide wheel supporting bracket so as to remove the deflection of the wire rope; the cable storage mechanism drives the cable storage reel to rotate through the cable storage winch; one end of the wire rope enters the rope guider after being coiled by the cable dragging reel, and then coils on the cable storage reel after being folded at 90 degrees by the guide wheel, and the cable storage winch performs the constant tension control on the wire rope. The retractable towing winch satisfies the demand of high load, big loading change and big rope capacity of the retractable towing winch of the submarine cable embedding machine.

Description

technical field [0001] The invention belongs to the field of supporting equipment for laying submarine cables of a cable laying ship, in particular to a retractable and unwinding towing winch of a submarine cable laying machine. Background technique [0002] The retractable towing winch of the laying machine is an important equipment for the cable laying ship to carry out the submarine cable laying operation. The general laying machine retractable towing winch adopts the traditional single-drum winch structure with multi-layer winding of steel wire rope. Its advantages are relatively simple structure and function, mature technology, easy application, and high reliability. However, the towing winch of the buried machine has its particularity in actual use. First of all, the working conditions of the winch are various, and the winch needs to be operated in combination with different working conditions to meet the corresponding operation requirements, which requires the winch ...

AI Technical Summary

Problems solved by technology

Due to the single working mode of the traditional single-drum winch, more manual participation is required when working with the mast, which not only easily causes the tension of the wire rope to relax, affects the winding, but also reduces the working efficiency

At the same time, for multi-layer winding winches, due to the large change in the load at the end of the wire rope, it is very difficult to ensure that the wire ropes are arranged neatly on the drum. , and cause friction and extrusion between the wire ropes, even biting the rope will shorten the service life of the wire rope
