A coupling hoist for unmanned ships that automatically retracts and retracts cables

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 present invention relates to a winch, in particular to a shaft-coupling winch used on an unmanned ship for automatically retracting cables and having an automatic cable discharge function, and in particular to an automatic retracting cable in the field of deck machinery for unmanned ships coupling hoist. Background technique [0002] The hoist, commonly known as the winch, is a light and small lifting device that uses a drum to wind a wire rope or chain to lift or pull heavy objects. The hoist can lift the weight vertically, horizontally or obliquely. device and safety protection device, etc., the driving device includes motor, coupling, brake, reducer, reel and other components, the wire rope winding system includes wire rope, reel, fixed pulley and movable pulley, and the pick-up device includes hook and ring , grab, electromagnetic sucker, spreader hanging beam and other forms, safety protection devices include overload limiter, lifting height ...

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

[0004] In addition, in high-end technical fields such as unmanned ships, it is often necessary to draw power from the dragged cable for use by electrical equipment, such as lamps or sonar, etc. In many applications, it is necessary to control the power on and off of the dragged and dropped device at any time In some applications, it is necessary to limit the on-off of the power supply of the load in different dragging and dropping sections, or lock it to prohibit power-on work during the retraction process, and the hoist commonly seen on the market must pass a hole on the roller shaft or disk. Lead wires are connected to the outside of the equipment, resulting in a large installation workload for users and complex structure of system equipment, which brings inconvenience to use and maintenance management. At the same time, it increases the occupied space and affects the aesthetics of the design.
