Description

Technical Field

[0001] The utility model relates to the technical field of anchor chains, in particular to an anchor chain capable of adding a counterweight. Background Art

[0002] Anchor chain is an important equipment connecting the anchor and the hull. It consists of a series of links and is used to fix the anchor to the seabed, maintain the ship's position at the anchorage, and prevent it from drifting or drifting away. Anchor chain plays a vital role in ship anchoring, operation and emergency situations. Its quality and performance are directly related to the safety and operating efficiency of the ship.

[0003] At present, the existing anchor chain is generally composed of an anchor end link, an intermediate link and an end link. The anchor end link is connected to the hull to transmit the gripping force of the anchor to the hull. When anchoring, the thrown anchor chain has a certain weight, which can buffer the external forces such as wind flow exerted on the ship in the water. The anchor chain lying flat on the bottom of the water keeps the force acting on the anchor horizontally, which is conducive to the reliable grip of the anchor. At the same time, this part of the anchor chain can also provide a part of the anchoring force due to the blocking effect of the soil.

[0004] In some cases, such as when the water depth exceeds a certain range or there are special environmental conditions, such as frequent typhoons, conventional anchor chains are difficult to provide sufficient restoring force when offset, which can easily lead to anchor failure. At present, large-diameter long anchor chains are generally used to increase the unit density of anchor chains, so that the length or diameter of the anchor chain suspended in the water increases, and the weight becomes heavier, thereby ensuring that sufficient restoring force can be provided when offset. However, this method requires the use of longer anchor chains, which has high manufacturing costs and more complicated construction. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide an anchor chain that can increase counterweight to solve the technical problems raised in the above background technology.

[0007] Preferably, a transfer link is provided between the end link and the middle link, and a connecting link is provided at one end of the transfer link away from the end link and the middle link.

[0008] Preferably, a buckling mechanism is provided at one end of the connecting link away from the transfer link, and the buckling mechanism consists of an outer buckling plate, an inner buckling plate, a return spring, a buckling groove, a push-pull block and a movable groove.

[0009] Preferably, one end of the external buckle plate is connected to the connecting chain link, a buckle groove is provided inside one side of the external buckle plate, a movable groove is provided inside the other side of the external buckle plate, an internal buckle plate is provided inside the movable groove, and a push-pull block is provided at one end of the internal buckle plate.

[0010] Preferably, a return spring is provided between the inner buckle plate and the movable groove, the inner buckle plate and the movable groove form an elastic structure through the return spring, and the inner buckle plate and the outer buckle plate form a locking structure through the buckle groove.

[0012] Preferably, a guide groove is provided inside the movable groove, a guide block is provided on one side of the inner buckle plate, and the inner buckle plate and the outer buckle plate form a sliding structure through the guide groove and the guide block.

[0013] In summary, the utility model mainly has the following beneficial effects:

[0014] The utility model uses a transfer chain link to form an integral structure of the middle chain link, the connecting chain link, the end chain link and the buckling mechanism, and because the inner buckle plate and the outer buckle plate are elastically connected by a reset spring, the inner buckle plate can be contracted toward the outer buckle plate by pushing the push-pull block. At this time, the outer buckle plate can be moved to the outside of the connecting ring. After the push-pull block is loosened, the inner buckle plate will be reset and engaged with the buckle groove under the action of the reset spring, thereby realizing the installation of the counterweight block on the anchor chain, making it easy to achieve balance and stability, helping to reduce the risk of vibration and overturning, and improving the stability and safety of the anchor chain.
