Description

Technical Field

[0001] The present invention relates to the technical field of ship mooring, and in particular to a ship mooring device. Background Art

[0002] A mooring device refers to a device used to fix the position of a ship when it is moored at a dock or anchorage. Common mooring devices include mooring ropes and mooring piles. These devices can ensure that the ship will not drift or leave the designated position during mooring, and ensure that the ship is safely moored and maintains a certain distance from the dock or other ships. Mooring devices play a very important role in operations such as ship mooring, loading and unloading of cargo. When a ship arrives at a dock or port, it needs to be moored. Mooring is to use a cable to safely and firmly tie the ship to the shore, and the other end of the cable is connected to the mooring pile on the ship.

[0003] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: During ship berthing operations, the ship is safely and reliably fastened to the mooring facilities of the dock or port by cables, and the other end of the cables is connected to the ship's mooring piles. However, in actual working conditions, affected by external environmental factors such as wind, waves and currents, the hull will produce lateral movement and drifting motion, causing the cables to bear periodic dynamic loads. Specifically, the displacement movement of the hull will cause the cables to frequently bear tensile stress. When the load exceeds the static threshold, the cables are prone to being over-tightened or subjected to excessive tension, which may cause cable wear and structural damage at the least, or even lead to breakage accidents at worst, posing a direct threat to ship safety and port operations.

A rotating plate 572 is provided on one side of the driven plate 574, and a long rod 573 is provided on the outside of the middle part of the rotating plate 572. The long rod 573 is rotatably connected to the shell 51. A lifting plate 571 is provided on one side of the rotating plate 572. The lifting plate 571 is connected to the arc plate 58 to reduce the influence of tension on the cable 23.

[0035] Working principle: During use, when the cable 23 needs to be wound up, the servo motor 21 on one side of the bracket 24 in the winch assembly 2 is started, and the servo motor 21 drives the winding drum 22 at the output end to wind up the cable 23, and the winding drum 22 is connected to the bracket 24 in rotation. At the same time, as the servo motor 21 is driven, the screw 32 is driven to rotate through the transmission belt 31, and the screw 32 is threadedly connected to the outer moving block 34, and the moving block 34 is slidably connected to the inner wall of the extension shell 33, and the extension shell 33 is fixedly connected to the base 1. Since the surface of the screw 32 has reverse threads symmetrically distributed, the two groups of moving blocks 34 move in opposite directions, so that the two groups of moving blocks 34 respectively drive the top connecting piles 35 to move in opposite directions, and as the winding drum 22 rotates, the cable 23 is wound up. The cable 23 passes through the opening 52 on the surface of the shell 51 in the dynamic rope-adjusting structure 5. Therefore, the dynamic rope-adjusting structure 5 moves synchronously while the cable 23 is wound, playing a guiding role. A guide component 53 is also rotatably connected to the inner side of the opening 52, and the guide component 53 includes a rotating rod 531 rotatably connected to the inner wall of the opening 52. The rotating rod 531 drives the outer rotating plate 532 to rotate. The rotating plate 532 is inclined. Multiple groups of rotating plates 532 form a trumpet shape. Therefore, the diameter of the guide component 53 can be adjusted according to the thickness of the cable 23. Multiple groups of rotating plates 532 can also remove impurities on the surface of the cable 23, so that the cable 23 is wound in an orderly manner. The dynamic rope-adjusting structure 5 moves synchronously and accurately guides. The trumpet-shaped guide adapts to cables 23 of different thicknesses and can also Impurities are removed, the smoothness of winding and the cleanliness of the cable 23 are ensured, and the efficiency of winding operation and the service life of the cable 23 are improved. Since a self-adjusting component 56 and an arc plate 58 are also provided inside the dynamic rope adjustment structure 5, and the cable 23 is wound around the surface of multiple sets of arc plates 58 twice, the surface of the arc plate 58 is correspondingly provided with a notch 581, and the inside of the notch 581 is also connected with a number of balls 582 that are rotatably connected at equal intervals. Therefore, the cable 23 is wound around the notch 581 on the surface of the arc plate 58, and the surface of the cable 23 contacts the number of balls 582. The cable 23 contacts the balls 582 when winding, and the balls 582 roll to prevent the surface of the cable 23 from being worn. When the ship is affected by wind and waves and floats and moves, a certain amount of pulling is generated on the cable 23, and excessive pulling force may cause damage. Therefore, it is necessary to unwind the cable 23 to reduce the tension. Since the cable 23 is wound on the surface of multiple sets of arc plates 58 inside the dynamic rope adjustment structure 5, the arc plates 58 will be pressed when the cable 23 has tension, and the arc plates 58 compress the spring three 569, thereby reducing the diameter of the multiple sets of arc plates 58, and the cable 23 wound on the surface of the arc plates 58 is loosened. At the same time, when the tension is greater, one set of arc plates 58 drives the lifting plate 571 on one side to move upward, and the lifting plate 571 lifts one end of the rotating plate 572. The rotating plate 572 rotates through the long rod 573 in the middle, and the long rod 573 is rotatably connected to the inner wall of the shell 51. Then the rotating plate 572 drives the driven plate 574 at the other end to move downward, and the driven plate 574 drives the rack 575 at the top to move downward.The rack 575 drives the protrusion 576 on one side to slide in the groove opened on the surface of the side plate 577. The protrusion 576 is meshed with the gear 578, so that the gear 578 drives the rotating column 561 to rotate, and the rotating column 561 drives the outer disc 562 to rotate. The surface of the disc 562 is provided with arc-shaped notches 563 at equal intervals. The inside of the notches 563 is respectively slidably connected with a slider 564. The slider 564 drives the slide 565 at one end to slide inward on the surface of the connecting plate 566. The connecting plate 566 is connected to the inner wall of the shell 51 through the connecting column 567. As the inner plate 56 8 moves inward, causing the arc plate 58 connected to the outer side of the inner plate 568 by the spring three 569 to also move toward the rotating column 561. At this time, the arc plate 58 does not support the cable 23 inward, and the diameter between the multiple sets of arc plates 58 is reduced, thereby having the effect of loosening the cable 23 and reducing the influence of the tension on the cable 23. The contact of the ball 582 reduces the wear of the cable 23 when it is reeled in. Under the action of tension, the arc plate 58 and other structures are linked to realize automatic loosening, effectively buffering the tension of the cable 23, reducing the risk of damage to the cable 23 caused by wind and waves, and ensuring the safety and durability of the cable 23 in complex working conditions.

[0036] As the ship floats and moves, the direction of the dynamic rope adjustment structure 5 is self-adjusted through the direction adjustment structure 4 set at the top of the connecting pile 35. When the ship swings to the left, the shell 51 rotates to the left under the tension. At this time, a group of ratchet pawl components in the direction adjustment structure 4 allows left rotation and is released, and the other group limits right rotation and is locked to avoid excessive right swing. When the ship swings to the right, the other group of ratchet pawl components is released, and the original locking group limits left swing, thereby realizing two-way adjustment of the follow-up limit. Specifically, when the ship swings, the shaft 41 rotates forward, and the pawl 143 slides along the tooth surface of the ratchet 142, allowing rotation in the same direction. The pawl 143 drives the spring 145 to squeeze and retract. The pawl 143 is rotatably connected to the fixed rod 144, and the fixed rod 144 is connected to the chassis 146. The tooth surface of ratchet 1 42 clamps pawl 1 43 to lock the reverse direction. Synchronously, when the rotating column 47 rotates in the reverse direction, pawl 2 49 adapts along the reverse tooth surface of ratchet 2 48 to allow reverse rotation. Pawl 2 49 squeezes and contracts spring 2 411. Pawl 2 49 is rotationally connected to fixed rod 2 410, and fixed rod 2 410 is connected to chassis 2 412. The reverse direction is locked by ratchet 2 48. Through the release and locking coordination of two sets of reverse pawls, the device can achieve adaptive steering with the bidirectional swing of the ship, while limiting excessive deflection and stabilizing the force on the cable 23.
