Description

Ship chain making device with good braking effect

Technical Field

The invention relates to the technical field of ship equipment, in particular to a ship chain making device with a good braking effect.

Background

The chain maker is an anchor chain fixing device which is arranged between an anchor machine and an anchor chain cylinder on a ship and used for fixing an anchor chain and preventing the anchor chain from sliding out, and during anchoring, the chain maker transmits tensile forces in various directions generated by the anchor and the anchor chain to a ship body so as to reduce the load of the anchor machine and protect the anchor machine; the working principle of the anchor machine is that a clamping plate arranged in front of a chain wheel clamps and fixes a single chain link in an anchor chain.

However, the existing chain making device has the following problems in the actual working process: firstly, because the anchor chain is formed by splicing chain links which are arranged in a staggered manner horizontally and vertically, when the existing chain maker clamping plate is used for pressing and fastening a single chain link, once the clamping position of the clamping plate is positioned in the anchor chain in a relatively vertical state, the anchor chain is very easy to turn over under the action of the tension of an anchor and an anchor machine, so that the anchor chain is easy to slip; and when the position of the anchor chain clamped by the clamping plate is at the front end in a relatively parallel state, the anchor chain can slide to a certain extent due to the tensile force of the anchor, so that the existing chain maker can cause the phenomenon that the fixed anchor chain slips and loosens under various acting forces when being clamped, and various acting forces on the anchor and the anchor chain can be directly transmitted to the anchor machine and damage the anchor machine, so that the chain maker cannot play a role in fixing the anchor chain and protecting the anchor machine, and secondly, because the weight of the anchor chain and the anchor chain at the bent angle of the chain maker is completely borne by the chain link at the bent angle, the friction force (pressure) borne by the chain link at the bent angle is maximum, thereby not only intensifying the abrasion of the anchor chain, but also influencing the speed of the anchor machine for receiving the anchor chain.
