Chain stopper

Abstract

The invention provides a chain stopper, and belongs to the field of deck machinery. The chain stopper comprises a bracket, a cable lifter, a chain stopping knife switch and adjusting gaskets, and thesupport comprises a first supporting plate and a second supporting plate. A first mounting groove is formed in the first supporting plate; a second mounting groove is formed in the second supporting plate; one end of the chain stopping knife switch is positioned in the first mounting groove; a plurality of the adjusting gaskets are clamped between the side wall, close to the cable lifter, of the first mounting groove and the chain stopping knife switch; the other end of the chain stopping knife switch is positioned in the second mounting groove; a plurality of the adjusting gaskets are clampedbetween the side wall, close to the cable lifter, of the second mounting groove and the chain stopping knife switch; and a pit is formed in the chain stopping knife switch after the pit is collided by an anchor chain, part or all of the adjusting gaskets in the first mounting groove and the second mounting groove can be taken out, and then the taken-out adjusting gaskets are mounted between the side walls, away from the anchor chain wheel, of the first mounting groove and the second mounting groove and the chain stopping knife switch, so that the distance between the chain stopping knife switch and the anchor chain wheel is reduced, and the chain stopping knife switch can still lock the anchor chain.

Description

technical field [0001] The present disclosure relates to the field of deck machinery, in particular to a chain stopper. Background technique [0002] On a ship, the anchor chain is usually retracted through the windlass, and the windlass is controlled to rotate forward and reverse, so as to realize the retraction and release of the anchor chain. After the windlass is braked, the anchor chain can be stopped. . Due to the sea wind and waves, after the windlass stops retracting, a huge pulling force will be generated on the anchor chain. The huge pressure directly acts on the windlass and may damage the windlass. Therefore, in order to avoid damage to the windlass, there is usually a There is a chain stopper to lock the chain after the windlass has stopped retracting the chain. [0003] The chain stopper generally includes a frame, an anchor wheel and a chain stop knife. The frame includes two support plates arranged oppositely. One end of the chain stop knife is hinged on a ...

AI Technical Summary

Problems solved by technology

[0004] In the actual use process, due to the influence of wind and waves, the anchor chain and the chain stop knife will collide repeatedly, and the chain stop switch knife will be subject to greater impact

After a period of time, the chain stop knife will be bumped out of the pit, causing the distance between the chain stop knife and the anchor chain wheel to become larger, so that the chain stop knife cannot lock the anchor chain
