Description

Technical Field

[0001] This utility model relates to the field of ship mooring guides, specifically a ship mooring guide to prevent mooring lines from jumping off. Background Technology

[0002] Ship mooring lines are the core load-bearing components in ship mooring operations. They are used to secure the ship to berths such as docks and buoys, transmit the mooring force to resist external forces such as wind, waves, and currents, and thus ensure the stability and safety of the ship during berthing. In order to achieve orderly guidance of the mooring lines and ease of operation, a guide line is required in the ship mooring system. As a mooring line guiding mechanism, the guide line is usually installed on the ship's deck. During the release of the mooring lines, it can guide the mooring lines to be released smoothly along a preset path, avoiding tangling, deviation, or hard friction with the hull structure. During the retrieval of the mooring lines, it can effectively limit and guide the mooring lines, ensuring that the mooring lines are neatly retrieved, reducing operational resistance and equipment wear, and ensuring the efficiency and safety of mooring operations.

[0003] During mooring and retrieval, the mooring line sways with the waves and the ship's movement, causing the contact point between the line and the guide to shake and jump. This could lead to the line completely detaching from the guide, thus affecting the mooring and retrieval operations. Therefore, a guide for preventing mooring line detachment is proposed to solve the aforementioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mooring guide to prevent mooring lines from jumping off. This solves the problem mentioned in the background art, where the mooring line sways due to waves and the floating of the ship, causing the contact point between the mooring line and the guide to sway and jump. This could lead to the mooring line completely detaching from the guide, thus affecting the mooring line deployment and retrieval operations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mooring guide for preventing mooring line slippage, comprising a base, on which a mooring guide assembly is provided, the mooring guide assembly including a turntable, the turntable being rotatably mounted on the base, the turntable having an installation groove, two connecting blocks connected within the installation groove of the turntable, a rotating rod rotatably connected between the two connecting blocks, a cable hook connected to the end of the rotating rod away from the connecting blocks, and an anti-slip buckle hinged to the cable hook.

[0006] Preferably, a coil spring is connected to the bottom inner wall of the turntable, and the end of the coil spring away from the turntable is connected to the base. The coil spring can use its elastic force to drive the rotated turntable to return to its original position.

[0007] Preferably, the anti-disengagement buckle can close the opening of the cable hook, and the end of the anti-disengagement buckle away from its hinge point is provided with a magnetic block, which can be magnetically attracted to the cable hook.

[0008] Preferably, two springs are connected in the mounting slot of the turntable, and the ends of the two springs away from the mounting slot are connected to the rotating rod.

[0009] Preferably, two sets of rollers are rotatably mounted on the cable hook, and the two sets of rollers are respectively located at two edges on the inner side of the cable hook.

[0010] Preferably, the system further includes a lubrication assembly comprising two liquid reservoirs, both of which are located on a turntable and on opposite sides of a mounting groove. Two air cylinders are connected to the outer wall of the turntable, and air pipes are connected to the air cylinders. The two air pipes are respectively connected to the two liquid reservoirs. Two pairs of contact rods are connected to the outer wall of the base, and the air cylinders are located between the pair of contact rods. Liquid pipes are installed inside each liquid reservoir. Inner tubes are installed inside the rotating rod and the cable hook, and both liquid pipes are connected to the inner tubes. Multiple extrusion tubes are installed inside the cable hook, and all of the multiple extrusion tubes are connected to the inner tubes. The end of each extrusion tube furthest from the inner tube protrudes from the inner side of the cable hook.

[0011] Preferably, the liquid tube is made of a flexible material, and the air cylinder can contact one of the abutment rods when it rotates with the turntable.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figures 1-3As shown, a mooring guide for preventing mooring line slippage includes a base 1, on which a mooring guide assembly 2 is mounted. The mooring guide assembly 2 includes a turntable 21, which is rotatably mounted on the base 1. The turntable 21 has a mounting groove, and two connecting blocks 23 are connected within the mounting groove. A rotating rod 24 is rotatably connected between the two connecting blocks 23. A hook 25 is connected to the end of the rotating rod 24 away from the connecting blocks 23, and an anti-disengagement buckle 27 is hinged to the hook 25. A coil spring 22 is connected to the inner bottom wall of the turntable 21, and the end of the coil spring 22 away from the turntable 21 is connected to the base 1. The coil spring 22 can use its elastic force to reset the rotated turntable 21. The anti-disengagement buckle 27 can close the opening of the hook 25. A magnet 28 is provided at the end of the anti-disengagement buckle 27 away from its hinge point, and the magnet 28 can magnetically attract the hook 25. Two springs 29 are connected within the mounting groove of the turntable 21, and the ends of the two springs 29 away from the mounting groove are both connected to the turntable 21. The rod 24 is connected; two sets of rollers 26 are rotatably mounted on the hook 25, and the two sets of rollers 26 are located at two edges on the inner side of the hook 25 respectively; the anti-disengagement buckle 27 is manually lifted upward to separate the magnetic block 28 from the hook 25, the cable is put into the hook 25, and then the anti-disengagement buckle 27 is released. The anti-disengagement buckle 27 falls naturally, and the magnetic block 28 is attracted to the hook 25 again, using magnetic force to lock the anti-disengagement buckle 27, so that the anti-disengagement buckle 27 is not easily opened by external force. When the cable is swaying due to the ship and waves, when the cable swings horizontally, the hook 25 swings horizontally with the cable. The hook 25 drives the turntable 21 to rotate horizontally through the rotating rod 24. When the cable no longer applies horizontal force, the turntable 21 can rotate and reset itself by the elastic force of the coil spring 22, and the hook 25 also resets. When the cable swings vertically, since the rotating rod 24 can rotate up and down between the two connecting blocks 23, the hook 25 can swing up and down with the cable.

[0025] In this embodiment, the cable guide assembly 2 is designed so that the anti-disengagement buckle 27 forms an annular space with the cable hook 25 after it is closed. This effectively prevents the cable from jumping off when it shakes. The inner roller 26 of the cable hook 25 can greatly reduce the wear on the cable during cable winding and unwinding operations, thereby extending the service life of the cable. Furthermore, the cable hook 25 can flexibly swing horizontally and vertically with the cable, so that the cable hook 25 always adapts to the movement angle of the cable, reducing the hard friction and pulling damage of the cable, and also reducing the impact force on the cable hook 25 when the cable shakes and jumps.

[0026] Example 2

[0027] Please see Figures 2-5As shown, it also includes a lubrication assembly 3, which includes two liquid tanks 31, both of which are located on the turntable 21. The two liquid tanks 31 are located on both sides of the mounting groove. Two air cylinders 32 are connected to the outer wall of the turntable 21, and air pipes 33 are connected to the air cylinders 32. The two air pipes 33 are respectively connected to the two liquid tanks 31. Two pairs of abutment rods 34 are connected to the outer wall of the base 1. The air cylinders 32 are located between a pair of abutment rods 34. Liquid pipes 35 are installed inside the liquid tanks 31. Inner tubes 36 are installed inside the rotating rod 24 and the cable hook 25. Both liquid pipes 35 are connected to the inner tubes 36. Multiple extrusion tubes 37 are installed inside the cable hook 25. The multiple extrusion tubes 37 are all connected to the inner tubes 36. The end of the extrusion tube 37 away from the inner tube 36 protrudes from the inside of the cable hook 25. The liquid pipes 35 are made of flexible material. The air cylinders 32 follow the turntable 21. When rotating, the cylinder 32 can contact one of the abutment rods 34. The cylinder 32 is provided with a telescopic end, which is arc-shaped. When the telescopic end of the cylinder 32 contacts the abutment rod 34, it is compressed by the counter-push force of the abutment rod 34. The two liquid chambers 31 are filled with lubricant. When the turntable 21 swings horizontally, the turntable 21 drives the two cylinders 32 on the outer wall to rotate synchronously. Taking one of the cylinders 32 as an example, when the cylinder 32 swings, its telescopic end contacts one of the abutment rods 34, so that the telescopic end is squeezed by the abutment rod 34. Then the cylinder 32 injects air into the liquid chamber 31 through the air pipe 33, so that the two liquid chambers 31 can use positive pressure to inject the lubricant inside them into the inner tube 36 through the two liquid pipes 35. The lubricant in the inner tube 36 is squeezed out to the inside of the cable hook 25 through multiple extrusion pipes 37.

[0028] In this embodiment, the lubrication component 3 enables multiple extrusion tubes 37 to extrude grease to the inside of the cable hook 25 when the turntable 21 swings. This allows a layer of grease to adhere to the roller 26 and cable inside the cable hook 25, improving the lubrication between the cable and the roller 26, further reducing cable wear, and thus protecting the cable.

[0029] This utility model discloses a mooring guide for preventing mooring line slippage. In use, the anti-slip buckle 27 is manually lifted upwards, separating the magnetic block 28 from the hook 25. The mooring line is then looped onto the hook 25. The anti-slip buckle 27 is then released, allowing it to fall naturally. The magnetic block 28 re-attaches to the hook 25, locking the anti-slip buckle 27 with magnetic force. This prevents the anti-slip buckle 27 from opening due to external forces. When closed, the anti-slip buckle 27 forms an annular space with the hook 25, effectively preventing the mooring line from slipping during vibrations. This keeps the mooring line stably within the hook 25. Workers use the hook 25 to traction and guide the mooring line. The mooring line inside the hook 25 directly contacts the two sets of rollers 26 on the hook 25. The rollers 26 roll with the mooring line, greatly reducing wear on the mooring line during retrieval and release operations, thus extending the mooring line's service life. When the cable moves due to the ship and waves, when the cable swings horizontally, the hook 25 swings horizontally with the cable. The hook 25 drives the turntable 21 to rotate horizontally through the rotating rod 24. When the cable no longer applies horizontal force, the turntable 21 can rotate back to its original position using the elastic force of the coil spring 22, and the hook 25 also returns to its original position. When the cable swings longitudinally, the rotating rod 24 can rotate up and down between the two connecting blocks 23, so the hook 25 can swing up and down with the cable. When the cable no longer applies longitudinal force, the rotating rod 24 uses the elastic force of the two springs 29 to drive the hook 25 to its original position, so that the hook 25 can flexibly swing horizontally and longitudinally with the cable, so that the hook 25 always adapts to the movement angle of the cable, reducing the hard friction and pulling damage of the cable, and also reducing the impact force on the hook 25 when the cable swings and jumps.

[0030] The two liquid tanks 31 are filled with lubricant. When the turntable 21 swings horizontally, the turntable 21 drives the two air cylinders 32 on the outer wall to rotate synchronously. Taking one of the air cylinders 32 as an example, when the air cylinder 32 swings, its telescopic end contacts one of the abutment rods 34, so that the telescopic end is squeezed by the abutment rod 34. Then the air cylinder 32 injects air into the liquid tank 31 through the air pipe 33, so that the two liquid tanks 31 can use positive pressure to inject the lubricant inside into the inner tube 36 through the two liquid pipes 35. The lubricant in the inner tube 36 is squeezed out to the inside of the cable hook 25 through multiple extrusion pipes 37, so that the roller 26 and the cable on the inside of the cable hook 25 can be coated with a layer of lubricant, which improves the lubrication between the cable and the roller 26, further reduces the wear of the cable, and plays a role in maintaining the cable.

[0031] The above embodiments are only used to illustrate the present utility model, and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
