An anchor speed limiting device for ship windlass

Abstract

The invention relates to the technical field of ship anchoring equipment, and discloses an anchoring speed limiting device for a ship anchor machine. The device comprises a base seat, wherein a left support is arranged on the top surface of the base seat; a protective shell positioned on the right side of the left support is arranged on the top surface of the base seat; a right support positionedon the right side of the protective shell is arranged on the top surface of the base seat; a transmission shaft is arranged at the top of the right support; and the left end of the transmission shaftpenetrates through the protective shell and is connected with the top of the left support. When anchoring, anchor chains rotate with anchor chain wheels to provide a centrifugal force for friction blocks, so as to enable the friction blocks to make centrifugal movement, after the friction blocks contact the inner walls of friction rings, part of the centrifugal force is converted into the pressureof the friction blocks on the friction rings, and thus the friction force between the friction blocks and the friction rings is increased, and the resistance of the anchor chain wheels to rotate is increased, so that the acceleration of the anchor chains out of the chains is decreased, and the reaction time reserved for carpenters is long, carpenters have sufficient time to operate the brake device, fatigue is not easy to occur, and the brake operation error rate is low.

Description

technical field [0001] The invention relates to the technical field of ship anchoring equipment, in particular to an anchor speed limiting device for a ship windlass. Background technique [0002] Ship windlass is a mechanical device used to retract and release anchors and anchor chains on ships. It is usually fixed on the deck of the first floor of the ship. It is mainly composed of bases, brackets, anchor chain wheels, braking systems, and power transmission systems. There are two wheels, one anchor chain wheel is equipped with a brake device on the outside to form a brake system, and the other anchor chain wheel is installed in the protective shell. When anchoring, the captain strictly controls the remaining speed of the ship, and analyzes the wind direction and sea current direction. The carpenter goes to the windlass and prepares to drop the anchor. After arriving at the scheduled anchor point, the anchor is thrown out, and the brake device is used to slow down the anch...

AI Technical Summary

Problems solved by technology

[0003] 1. In the process of anchoring, the speed of the chain out of the anchor chain increases rapidly, and the acceleration is very large. The reaction time reserved for the carpenter is short. The carpenter needs to concentrate on observing the speed of the chain out and operate the brake device accurately, which is prone to fatigue. Brake operation error rate is high

[0004] 2. If the brake operation is wrong, the anchor chain will be too long and the speed will be too fast. At this time, the brake device will be tightened, and the brake belt will bear a lot of force. The brake belt will be damaged at the slightest, and the anchor chain will lose control and cause loss. The occurrence of anchor accidents, resulting in ship collision or grounding, resulting in greater losses
