Coupling hoist achieving automatic cable take-up and pay-off for unmanned ship

Abstract

The invention provides a coupling hoist achieving automatic cable take-up and pay-off for an unmanned ship. The coupling hoist comprises a motor, a coil, a coil support, a reset spring, a conduction contact piece, a drum shaft, a drum, a cable arrangement wheel shaft, a cable arrangement wheel, a reciprocating wire, a first chain wheel, a second chain wheel, a screw rod base and a screw rod sliding block. The coupling hoist achieving automatic cable take-up and pay-off is mainly applied to the field of unmanned ship deck machinery, a load power supply relay contact switch module and a chain wheel driving reciprocating automatic cable arrangement wheel are designed, the problem that an existing hoist needs to lead a power supply line out of a drag cable to be supplied to electric equipment for use is solved, and meanwhile the problems that in the prior art, coiling is messy, so that the space utilization rate of the drum and a cable containing bin is low, and equipment is likely to be damaged due to cable jamming are solved; a sensor, a PLC, an expert system and the like are arranged on the hoist, automatic control can be achieved, certain intelligence is achieved, and the device has the advantages of being simple in structure, few in fault points, easy to operate, free of maintenance, capable of conducting self-diagnosis, remote monitoring and maintenance and the like.

Description

technical field [0001] The invention relates to a hoist, in particular to a coupling hoist used for automatically retracting and unwinding cables on an unmanned ship and having an automatic cable arranging function, in particular to an automatic retractable cable in the field of unmanned marine deck machinery. coupling winch. Background technique [0002] The winch, commonly known as the winch, is a light and small lifting device that uses a reel to wind a wire rope or chain to lift or pull heavy objects. The winch can lift heavy objects vertically, horizontally or obliquely. It is composed of equipment and safety protection devices. The driving device includes motors, couplings, brakes, reducers, reels and other components. The wire rope winding system includes wire ropes, reels, fixed pulleys and movable pulleys. The pick-up device has hooks and rings. , grab bucket, electromagnetic sucker, spreader hanging beam and other forms, safety protection devices include overload ...

AI Technical Summary

Problems solved by technology

[0003] In the current hoist, the messy winding of the cable is also a serious problem. The messy winding of the cable will seriously reduce the original space utilization and distribution efficiency of the drum and the cable storage compartment, and even cause the coil to overflow the storage capacity, which is harmful to the equipment. The use of the hoist will cause great inconvenience, and may cause damage to the equipment due to the inappropriate retractable position. The messy winding of the hoist will also cause another serious problem. When the cables are laid next time, the cables may be caused by mutual compression or even entanglement. It greatly hinders the pulling out of the cable, prolongs the pulling out time or even jams the cable, which greatly interferes with the work. For some applications, the difficulty of pulling the cable may cause damage to the equipment
