[0022] like Figure 1 As shown, a ship cable taking-up and releasing device is characterized in that: it includes a workbench 1 and a taking-up and releasing device 2, a first fastening device 3, a second fastening device 4, a height adjustment device 5 and a fairlead 6 arranged on the workbench 1, the taking-up and releasing device 2 is installed between the first fastening device 3 and the second fastening device 4 and the first fastening device 3 and the second fastening device 4 are arranged opposite to each other; the taking-up and releasing device 2 includes a taking-up and releasing mounting disk 21, a column 22 and a gear 26; the column 22 is fixed to the mounting disk 21, the top end of the column 22 is detachably connected to the cover body 24, the bottom of the mounting disk 21 is fixed to a rotating shaft 25, the rotating shaft 25 is fixed to a gear 26, the driving motor is engaged with the gear 26 through the meshing gear, so that the driving motor can rotate the taking-up and releasing device 2.
[0023] like Figure 2 As shown, the cable retraction and deployment device also includes a widening column 27, which is mounted on the mounting plate 21. The widening column 27 increases the overall width of the cable retraction and deployment device 2, thereby improving its stability. Especially when the ship is rocking or encountering harsh sea conditions, the widening column can effectively prevent capsizing or instability during cable retraction and deployment. The design of the widening column 27 allows the cable retraction and deployment device to accommodate cables of varying diameters, increasing the device's versatility and flexibility.
[0024] The cable also includes a cable drum 23, which is mounted on the upright post 22 and slidably connected to the upright post 22. The cable drum 23 is heavy. After the cable is stowed, the cover 24 is opened and the cable drum 23 is installed. The heavy weight of the cable drum 23 effectively holds down the stowed cable, preventing it from becoming loose or tangled due to the ship's swaying or external environmental influences, and keeping the cable neat and orderly. When the cable is needed, the cover 24 is simply opened and the cable drum 23 is removed.
[0025] like Figure 3 As shown, the first fastening device 3 includes a fastening cylinder 32, a first fastening arm 33 and a second fastening arm 34; the cylinder body of the fastening cylinder 32 is mounted on the fastening mounting plate 31, and the free end of its piston rod is connected to the first fastening arm 33 through a connecting block; the first fastening arm 33 and the second fastening arm 34 are both rotatably connected to the fastening mounting plate 31, the first fastening arm 33 is provided with a first gear ring 331, and the second fastening arm 34 is provided with a second gear ring 341, the first gear ring 331 is engaged with the second gear ring 341, and the first fastening arm 33 and the second fastening arm 34 are both provided with a fastening head 35. Figure 3 The middle figure shows an open position. When the cable needs to be tightened, the free end of the piston rod of the tightening cylinder 32 extends, driving the first tightening arm 33 to rotate clockwise. Because the first gear ring 331 is engaged with the second gear ring 341, the second tightening arm 34 rotates counterclockwise, and the two tightening arms approach each other. The first tightening device 3 and the second tightening device 4 are closed to fix the cable. The closing action of the tightening arm is controlled by the cylinder, which ensures the stability of the cable in a fixed state and reduces the risk of accidental loosening due to human factors. Especially in offshore working environments. The first tightening device 3 and the second tightening device 4 have the same structure. The two tightening devices tighten the cable from both sides, which can more evenly distribute the force on the cable and reduce damage caused by excessive local force. This helps to extend the service life of the cable and reduce maintenance costs.
[0026] like Figure 4 As shown, the height adjustment device 5 includes a height adjustment mounting base 51, a height adjustment motor 52, and an adjustment plate 54. The height adjustment motor 52 is mounted on the height adjustment mounting base 51, with its output end connected to a screw 53 via a speed reducer. The adjustment plate 54 is threadedly connected to the screw 53, and a hook 55 is fixed to the adjustment plate 54. The hook 55 can be a D-shaped hook with a hinged opening for passing a cable. A reinforcement rod 56 is provided on the mounting base 51 and is slidably connected to the adjustment plate 54.
[0027] When the adjustment motor 52 is working, it drives the screw rod 53 to rotate, thereby moving the adjustment plate 54 up or down, and driving the hook 55 to move up and down. During installation, a screw rod 53 with the same winding height as the retracting device 2 should be used. Through the height adjustment device 5, it can be ensured that the cable is evenly wound on the retracting device 2 during the retracting process. The up and down movement of the adjustment plate 54 can arrange the cables layer by layer, avoid too many knots at the same height, and keep the cables neat and orderly. The evenly wound cable is more stable on the retracting device, reducing the safety hazards caused by loosening or falling off of the cable. Especially when the ship is shaking or encountering severe sea conditions, it can effectively prevent the cable from loosening or falling off due to inappropriate height, thereby improving the safety of operation.
[0028] like Figure 5 As shown, the fairlead 6 includes a fairlead mounting plate 61 and a guide wheel 62; the fairlead mounting plate 61 is slidingly connected to a first roller group 63 and a second roller group 64, the first roller group 63 includes a bracket and a first roller 631, the first roller 631 is rollingly connected to the bracket, the second roller group 64 includes a bracket and a second roller 641, the second roller 641 is rollingly connected to the bracket, and the guide wheel 62 is also rollingly connected to the fairlead mounting plate 61.
[0029] The fairlead mounting plate 61 is provided with a slide rail 611, and sliders are provided at the bottom of the first roller group 63 and the second roller group 64. The sliders are slidably connected to the slide rail 611. The first roller group 63 and the second roller group 64 are also provided with a limiting mechanism. The limiting mechanism enables the first roller group 63 and the second roller group 64 to be fixed to the fairlead mounting plate 61 after being moved.
[0030] The fairlead 6 guides the cable through the guide wheel 62 and the roller group, ensuring that the cable moves along the predetermined path during the retraction and deployment process, preventing the cable from deviating or going off track. The first roller group 63 and the second roller group 64 can slide on the slide rail, and the position of the rollers can be adjusted according to actual needs to adapt to cables of different lengths and diameters. Through the guidance of the fairlead, the operator can more easily control the cable, reducing manpower requirements. The various components of the fairlead, such as the rollers and guide wheels, are independent modules, which are easy to replace and repair. If a component is damaged, it can be quickly replaced, reducing downtime and maintenance costs.
[0031] The device is also equipped with a control device for controlling the drive of each component. During use, when the cable needs to be released, the cable is wrapped around the column 22, and the end of the cable is fixed to the column 22 of the retracting and unfolding device 2. The cable can be wrapped in an "8" shape or tied to the column 22 to prevent the cable from falling off during the release process. The end of the cable passes through the hook 55 and is guided by the roller group of the fairlead 6. The guide wheel 62 ensures that the cable moves along the predetermined path. The drive motor is controlled to rotate the retracting and unfolding device 2, and the cable is released. When the cable needs to be retracted, the drive motor is controlled to reverse. When the cable begins to wrap around the retracting and unfolding device 2, the height adjustment motor 52 is activated. The height adjustment motor drives the screw rod 53 to rotate through the reducer, causing the adjustment plate 54 to move up and down. The hook 55 on the adjustment plate 54 moves up and down accordingly, ensuring that the cables are evenly arranged layer by layer on the retracting and unfolding device 2, avoiding excessive winding or knotting at the same height. When retraction is completed, the retracted cable end is at the same height as the fastening device. When the cable needs to be fixed, the tightening cylinder 32 is started, the two tightening arms approach each other, the first tightening device 3 and the second tightening device 4 are closed, and the cable is fixed. The operator checks whether the cable is firmly fixed and ensures that the tightening head 35 has tightly clamped the cable. When the cable is completely retracted, the cover 24 is opened and the rope pressure drum 23 is installed on the column 22. The rope pressure drum 23 has a certain weight and can effectively press down the retracted cable to prevent the cable from becoming loose or tangled due to the shaking of the hull or the influence of the external environment. When the cable needs to be used, the cover 24 is opened and the rope pressure drum 23 is removed. Operate the tightening cylinder 32 to retract the free end of its piston rod, drive the first tightening arm 33 to rotate counterclockwise, the second tightening arm 34 to rotate clockwise, the two tightening arms open, and then release the cable.
[0032] It should be noted that the hook 55 and the limiting mechanism in this embodiment are universal standard parts or components known to those skilled in the art, and the motor and cylinder in this embodiment meet certain waterproof standards. Their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.
[0033] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments. Any changes or modifications based on the present invention fall within the scope of protection claimed by the present invention.
