Description

Technical Field

[0001] The invention belongs to the technical field of ship windlasses, and in particular relates to a ship windlass with an anti-jamming gear mechanism. Background Art

[0002] The ship's windlass is a key device used on board to lift and lower the anchor. In the marine environment, the windlass often faces various challenges. For example, foreign objects such as sand, mud, and seaweed in the sea water can easily enter the gear system, causing the gears to get stuck or damaged. In addition, long-term use and wear will also increase the risk of gear jamming. These problems will not only affect the normal operation of the windlass, but may also cause equipment failure and affect the safe navigation of the ship. Therefore, it is necessary to propose a ship windlass with an anti-jamming mechanism.

[0003] The existing ship windlass still has the following shortcomings:

[0004] 1. When the existing ship windlass is in use, due to the harsh marine use environment, the loss of the anchor chain will be greatly increased. When the existing ship windlass is winding the anchor chain, it lacks a guiding mechanism for the anchor chain, which causes the anchor chain to be excessively concentrated in the middle of the winding drum during winding. This not only makes the wear progress of the middle of the winding drum much faster than that of the two sides, but also greatly increases the pressure on the inner layer of the anchor chain on the winding drum, which seriously affects the service life of the windlass and the anchor chain.

[0005] 2. When the existing ship windlass is in use, foreign objects such as sand, mud, seaweed, etc. in the seawater are easily stuck in the anchor chain, which is easy to cause the anchor chain to deform during winding. The debris in the anchor chain will cause uneven force at different positions of the anchor chain during winding, resulting in the safety of the anchor chain being unable to be guaranteed.

[0006] 3. When the existing ship anchor winch is in use, the anchor winch lacks safe and effective braking measures. When the anchor winch encounters mechanical failure, motor power failure, anchor chain breakage, etc., the anchor chain may continue to move, causing uncontrollable situations, and also causing irreversible impact on the safety of ship driving.
