Description

Technical Field

[0001] The invention relates to the technical field of marine machinery, and in particular to a positioning anchor frame anchor cable limiting device and method. Background Art

[0002] The anchor is the main component of the ship's mooring equipment. It is used to temporarily anchor the ship while sailing. It sinks to the bottom of the water and hooks onto the reefs or other obstacles on the bottom of the water to give the rope connected to the anchor a strong pulling force, so that the hull floats within a certain range and is not affected by water currents and wind currents.

[0003] The invention with publication number CN112124495A discloses an automatic sand replenishing ship anchoring device, comprising a ship deck, an anchor fixing base is fixedly provided on the left side of the upper end surface of the ship deck, an anchor shaft support plate is fixedly provided on the front and rear sides of the upper end surface of the anchor fixing base, an anchor shaft is rotatably provided between the rear end surface of the front anchor shaft support plate and the front end surface of the rear anchor shaft support plate, a chain cylinder is fixedly provided on the outer circumferential surface of the anchor shaft, an inclined sand trough cavity with an opening upward is provided in the ship deck, and a chain cavity with an opening downward is connected to the lower side of the sand trough cavity. The present invention can complete the retraction and deployment of the anchor, and by arranging the sand trough, the friction of the anchor connecting chain is reduced, the speed of retracting and deploying the anchor is accelerated, and the wear of the connecting chain is reduced. At the same time, the device can automatically replenish the sand in the sand trough when retracting and deploying the anchor, so as to avoid the failure of the sand trough due to the failure to replenish in time after the sand is reduced.

[0004] The utility model with the publication number CN209366379U discloses an oil tanker anchor that is easy to retract, including a base, a second rotating shaft, a winding wheel and a fourth telescopic rod, a frame is arranged above the base, and a first telescopic rod is arranged at the rear of the inner part of the frame, a second telescopic rod is arranged at the front of the inner part of the frame, and the inner side of the left end of the second telescopic rod and the first telescopic rod is connected through the first rotating shaft, and a roller is arranged between the first rotating shafts, the second rotating shaft is arranged at the inner side of the frame, and the second rotating shaft passes through the front side wall of the frame, a control rod is arranged in front of the second rotating shaft, and a third telescopic rod is arranged on the inner surface of the control rod, and the third telescopic rod is engaged in a slot, and the slot is opened on the front side surface of the frame. The oil tanker anchor that is easy to retract is provided with a first telescopic rod, a second telescopic rod and a roller, the first telescopic rod and the second telescopic rod can be extended out of the ship, and the rope passes through the roller to lower the anchor, and the roller can make the anchor easier to retract.

[0005] However, the above patent still has the following problems:

[0006] (1) In the prior art, when lowering the anchor, the entire anchor chain will be released due to gravity. However, the seabed is higher as it approaches the land. After the anchor is lowered, the higher the seabed is, the shorter the distance required for the anchor to contact the seabed will be. After the anchor contacts the seabed, the anchor chain will continue to be released due to gravity, resulting in the need to lower the anchor in advance when the ship is docked at the coast. Therefore, when encountering some emergencies, the ship cannot be stopped quickly even if the anchor is lowered, resulting in collision accidents.

[0007] (2) In the prior art, when the anchor is lowered to stop the ship, the drum in the recovery device will rotate due to inertia, causing the anchor chain to swing. The swinging anchor chain is likely to collide with the ship, causing the paint to fall off locally on the ship, and then rust, shortening the service life of the local part of the ship.

[0031] (1) The present invention provides a main limit mechanism and a secondary limit mechanism.

In the event of an emergency, the descending length of the anchor chain can be controlled according to the height of the seabed, thereby quickly stopping the hull and reducing the occurrence of accidents.

[0032] (2) A check assembly is provided. When the anchor chain completely slides down, it will generate rebound inertia due to gravity and rise a certain distance, thereby driving the recovery drum to rotate. The telescopic rod is retracted through the telescopic tube, and the spring drives the abutment plate to reset. The lower end of the abutment plate contacts the outer side of the connecting saw gear. When the recovery drum drives the connecting saw gear to rotate, the outer side of the connecting saw gear is pressed against the lower end of the abutment plate, so that the drum stops rotating, thereby preventing the anchor chain from swinging and colliding with the hull, causing the paint to fall off locally on the hull, and then rusting, thereby shortening the service life of the local part of the hull.
