Safety clutch of anchor windlass and control method thereof

Abstract

The invention relates to a safety clutch of an anchor windlass and a control method of the safety clutch of the anchor windlass and belongs to the technical field of clutches of the anchor windlasses.The safety clutch of the anchor windlass comprises a cable lifter. The cable lifter is provided with a main shaft which is connected with the cable lifter in a sleeved manner. A plurality of shaft sleeves are arranged between the main shaft and the cable lifter. The main shaft is provided with a clutch assembly which is in contact connection with the cable lifter in a movable engagement manner. Acable lifter tiger claw is arranged between the clutch assembly and the cable lifter and is integrated with the cable lifter. An engagement and disengagement hand wheel shaft which is connected withthe main shaft in a sleeved manner is arranged in the clutch assembly. The engagement and disengagement hand wheel shaft is provided with a limiting press plate which is in bolted connected with the end face of the main shaft in a flanged manner. The engagement and disengagement hand wheel shaft is in sleeved connection with the clutch assembly in a threaded manner, and the engagement and disengagement hand wheel shaft extends out of the outer end of the clutch assembly. The safety clutch has the advantages of being stable in operation, convenient to operate and long in service life; the problem that since a clutch is engaged with the cable lifter and gets stuck, the clutch cannot achieve normal disengagement is solved; the accidents that the main shaft bends due to torque overload, a gearof a speed reducer is broken due to torque overload of the speed reducer and a coil is burned out due to current overload of the motor are prevented, and the safety clutch achieves the safety protection function.

Description

technical field [0001] The invention relates to the technical field of windlass clutches, in particular to a windlass safety clutch and a control method thereof. Background technique [0002] At present, due to the continuous development of fishery resources, the windlass has become an indispensable tool, and if the clutch is not used during the operation of the windlass, due to the heavy penetration force of the anchor during the period between the end of the anchor and the beginning of the anchor Large, the damage to the hydraulic motor or electric motor is very large, which affects the work efficiency and the service life of the entire windlass. The clutch device on the marine windlass is mainly used to cut off or transmit the power input from the power machine to the transmission, and it is an important device to ensure the normal operation of the windlass. [0003] The clutch mode of the prior art is to shake the handwheel clockwise, so that the clutch slides along the...

AI Technical Summary

Problems solved by technology

[0004] The invention mainly solves the problem in the prior art that when the anchor is stuck, the clutch and the anchor chain wheel cannot be separated normally, and provides a windlass safety clutch and its control method. The windlass safety clutch has the characteristics of stable operation, easy operation Advantages of convenience and long service life

Its control method solves the problem that the clutch cannot be disengaged normally due to the clutch and the chain wheel being stuck.
