Description

Technical Field

[0001] This utility model relates to the technical field of anti-slip and friction-reducing devices for cables, specifically to a dock mooring friction-reducing device. Background Technology

[0002] When a ship needs to berth at a dock, it will experience a certain degree of swaying due to natural factors such as waves and wind. When a ship needs to berth near the shore, the mooring lines need to be manually wound around bollards on the shore. Due to the influence of waves and wind, the ship continuously sways and shifts relative to the shore. Because the angle between the ship and the dock is different, the mooring lines between the ship and the shore will bear significant swaying and tensile forces, leading to severe wear and tear on the lines and posing a potential safety hazard for the ship. Currently, most ships use wooden blocks to lay the mooring lines to reduce friction between the lines and the deck. However, the lines experience significant friction with the blocks during swaying, and the blocks are prone to rapid damage and unusable.

[0003] Chinese patent CN213800073U discloses a spliced ​​dock mooring friction reduction device that utilizes self-lubricating pads to reduce friction and ensure mooring safety. Its splicable design allows for continuous splicing, temporary installation, or permanent installation using expansion bolts. The pads are made of self-lubricating polymer materials, significantly improving the mooring friction reduction effect.

[0004] However, in actual use, when the ship and the mooring line tilt and sway significantly due to natural wind factors, the above structure can easily cause the mooring line and the pad to detach from each other. This makes it difficult to limit and buffer the swaying and deviating mooring line, which indirectly reduces the service life of the mooring line. Utility Model Content

Detailed Implementation

[0029] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] To achieve fully automated grinding of kettle welds, and to solve the following technical problems, such as... Figure 1 , 3 As shown in Figures 4, 5, and 6,

[0031] A friction-reducing device for dock mooring lines includes a mounting plate 1, a movable block 2, rounded corner plates 3, and a circular rod 4. The mounting plate 1 is a cuboid with rounded corners on all four sides. The movable block 2 is installed on the upper part of the mounting plate 1. The rounded corner plates 3 are evenly distributed around the mounting plate 1. The circular rod 4 is installed on the upper part of the mounting plate 1. The friction-reducing device also includes an anti-slip block 5, a travel groove, and a locking screw 7. The travel groove is formed inside the mounting plate 1, and the movable block 2 can slide left and right along both sides of the travel groove. The anti-slip block 5 is installed at the bottom of the mounting plate 1 to prevent the mounting plate 1 from moving freely on the deck. The locking screw 7 is installed inside the rounded corner plate 3 and is threadedly connected to the rounded corner plate 3. The locking screw 7 is used to quickly install the mounting plate 1 onto the deck.

[0032] The friction reduction device also includes a placement block 2a1, a torsion spring 2a2, a guide wheel 2a3, and a semi-circular clamping block 2a4. The placement block 2a1 is installed on the upper part of the mounting plate 1 and is shaped like a lower semi-circle. The torsion spring 2a2 is installed on one side of the placement block 2a1, and a movable cavity for the torsion spring 2a2 to move is opened on one side of the placement block 2a1. The guide wheel 2a3 is located on one side of the moving block 2 and is used to abut against the moving block 2 and to make the two sets of moving blocks 2 move closer to each other. The semi-circular clamping block 2a4 is installed on the upper part of the mounting plate 1 and can place the cable into the upper part of the semi-circular clamping block 2a4.

[0033] The telescopic spring 2a2 drives the two sets of moving blocks 2 and the semi-circular clamping block 2a4 to move closer to each other. Similarly, when the moving block 2 moves and comes into contact with the side wall of the semi-circular clamping block 2a4, the guide wheel 2a3 can come into contact with the semi-circular clamping block 2a4 and rotate, thereby reducing the friction of the guide wheel 2a3 on the semi-circular clamping block 2a4.

[0034] like Figure 4 , 5 As shown, preferably, the movable block 2 further includes an arc-shaped mounting plate 2a5, ball bearings 2a6, a first mounting plate 2a7, and a second mounting plate 2a8; the arc-shaped mounting plate 2a5 is disposed on one side of the semi-circular clamping block 2a4, and the inner diameter of the arc-shaped mounting plate 2a5 matches that of the semi-circular clamping block 2a4; the ball bearings 2a6 are circumferentially and detachably mounted between the semi-circular clamping block 2a4 and the arc-shaped mounting plate 2a5, and the ball bearings 2a6 can contact the swaying cable, reducing the coefficient of friction between the ball bearings and the cable, and reducing the swaying amplitude of the cable; the first mounting plate 2a7 is mounted on the upper part of the arc-shaped mounting plate 2a5, and the arc-shaped mounting plate 2a5 and the first mounting plate 2a7 are arranged in the same direction; the second mounting plate 2a8 is mounted on the upper part of the semi-circular clamping block 2a4.

[0035] Two sets of semi-circular clamping blocks 2a4 abut against each other to clamp and fix the cable, which can limit the range of motion of the cable and self-reset the swaying and deviating cable. At the same time, the self-lubricating pad 2a7 can lubricate the swaying cable, reduce the friction range of the cable, and indirectly improve the service life of the cable.

[0036] like Figure 5 , 6 As shown, it also includes a first hook 4a1, a flexible baffle 4a2, a tension spring 4a3, and a second hook 4a4; the first hook 4a1 is installed on the outside of the circular rod 4, and there are two first hooks 4a1 arranged horizontally; the flexible baffle 4a2 is arranged on one side of the first hook 4a1, and the flexible baffle 4a2 is arranged horizontally with the moving block 2; there are two second hooks 4a4, and multiple second hooks 4a4 are arranged facing each other on the other side of the moving block 2, and the second hooks 4a4 are installed on the other side of the moving block 2.

[0037] While the moving block 2 moves, a flexible baffle 4a2 is provided at its rear to shield and cover the upper part of the travel groove, avoiding corrosion from humid air and seawater, improving the service life of the guide rod 2a1 and the telescopic spring 2a2, and the flexible baffle 4a2 can be disassembled and cleaned and replaced by the first hook 4a1 and the second hook 4a4.

[0038] like Figure 7As shown, the locking screw 7 also includes a cover plate 7a, a first rubber sleeve 7b, and a second rubber sleeve 7c; the cover plate 7a is rotatably mounted on one side of the mounting plate 1, and the cover plate 7a is rotatably located on the upper part of the locking screw 7, and the cover plate 7a and the locking screw 7 are vertically arranged; the first rubber sleeve 7b is installed on the outer wall of the locking screw 7, and the first rubber sleeve 7b is clearance-fitted with the locking screw 7; the second rubber sleeve 7c is located on the lower part of the rounded corner plate 3, and the second rubber sleeve 7c is clearance-fitted with the locking screw 7.

[0039] Use tools to rotate the locking screw 7 to fix the device onto the deck. In the initial stage of installing the locking screw 7, first pull the cover plate 7a upwards, and then put the first rubber sleeve 7b and the second rubber sleeve 7c onto the outer wall of the locking screw 7 and onto the upper and lower parts of the rounded corner plate 3, so that the locking screw 7 can be externally wrapped after installation.

[0040] like Figure 7 As shown, it also includes a reset spring 7d; the reset spring 7d is installed on the outside of the mounting plate 1, and the lower part of the cover plate 7a is fixedly connected to the reset spring 7d.

[0041] The return spring 7d pulls the cover plate 7a until the cover plate 7a covers the upper part of the locking screw 7, thus avoiding the locking screw 7 from being unable to be disassembled smoothly due to corrosion problems during disassembly.

[0042] The working principle of this utility model:

[0043] First, by grasping the handle on the upper part of the semi-circular clamping block 2a4, the moving block 2 is pulled outward, while the semi-circular clamping block 2a4 unfolds. Then, the cable is passed through the upper part of the placement block 2a1. When the moving block 2 is released, the telescopic spring 2a93 drives the two sets of moving blocks 2 and the semi-circular clamping blocks 2a4 to move closer together. Similarly, when the moving block 2 moves and contacts the side wall of the semi-circular clamping block 2a4, the guide wheel 2a3 contacts and rotates with the semi-circular clamping block 2a4, thereby reducing the friction between the guide wheel 2a3 and the semi-circular clamping block 2a4 until the two sets of semi-circular clamping blocks 2a4 are pressed together, completing the clamping and fixing action of the cable. This limits the range of motion of the cable. The system controls and self-resets swaying and deviating cables. The lubricating pad 2a91 lubricates the swaying cable, reducing friction and indirectly improving its lifespan. The ball bearing 2a6 can be removed from the semi-circular clamping block 2a4 by rotating the bolt 2a9, facilitating its replacement. As the moving block 2 moves, a flexible baffle 4a2 at its rear covers and shields the upper part of the travel groove, preventing corrosion from humid air and seawater, thus extending the lifespan of the guide rod 2a1 and the telescopic spring 2a2. The flexible baffle 4a2 can be disassembled for cleaning and replacement via the first hook 4a1 and the second hook 4a4.

[0044] When quickly installing the device, use a tool to rotate the locking screw 7 to fix the device onto the deck. In the initial stage of installing the locking screw 7, first pull the cover plate 7a upwards, and then put the first rubber sleeve 7b and the second rubber sleeve 7c onto the outer wall of the locking screw 7 and onto the upper and lower parts of the rounded corner plate 3, respectively. This can wrap the locked screw 7 externally after installation to avoid corrosion from the humid air and seawater. After installation, when you release the pull of the cover plate 7a, the return spring 7d pulls the cover plate 7a until the cover plate 7a covers the upper part of the locking screw 7. This avoids the locking screw 7 from being unable to be disassembled smoothly due to corrosion problems.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
