Description

Technical Field

[0001] This invention relates to the field of mooring bollard technology, specifically a marine mooring bollard. Background Technology

[0002] Marine mooring bollards are typically made of cast iron or cast steel. While a layer of paint is applied during manufacturing to prevent rust and improve surface smoothness, in coastal environments, if damaged paint isn't promptly repainted to maintain a smooth surface, seawater and humid air can corrode the bollards. The presence of oxides causes the surface to become rough and develop sharp scale. During mooring, the ship's movement causes friction and slippage between the rope and the bollard. This friction, like a file, can easily abrade the rope, cutting fibers and reducing its tensile strength, shortening its lifespan and making it more prone to breakage. Furthermore, conventional mooring bollards are often cast as a single piece, making surface repair difficult once rust develops, and replacing an entire bollard is prohibitively expensive. Summary of the Invention

[0003] The purpose of this invention is to provide a marine mooring bollard to solve the problem that when mooring bollards are used in coastal environments, surface oxidation of the mooring bollard can easily cause surface abrasion and fiber cutting of the rope, resulting in a decrease in the tensile strength of the rope. At the same time, it also solves the problem that mooring bollards made of integral casting are difficult to maintain and have high replacement costs.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A marine mooring bollard includes a base, a first bollard and a second bollard, and two bollard caps. The first and second bollards are symmetrically arranged on the base and are both vertically arranged. The two bollard caps are coaxially arranged at the top of the first and second bollards, respectively. Specifically, the bollard caps are bolted to the first and second bollards. At least three rubber rings are coaxially arranged on each of the first and second bollards, and the rubber rings are slidably connected to the first and second bollards. A mooring ring is coaxially arranged on the outer wall of each rubber ring, and the mooring ring is fixedly connected to the rubber ring, and the height of the mooring ring and the rubber ring is the same.

[0005] By installing rubber rings and mooring rings on the outer walls of piles No. 1 and No. 2, the rope is wound around multiple mooring rings during mooring. When the ship is subjected to high and low tides, waves, or human influence causing swaying, the tension on the rope increases, causing the rubber rings to compress and deform. This deformation of the rubber rings provides a buffer and compensation for the rope, preventing breakage and improving the safety of the ship during mooring. Furthermore, even if there is small-area corrosion on the surface of the mooring rings, the increased tension on the rope during ship swaying increases the friction between the mooring rings and the rope. Because the rubber rings are allowed to twist, they twist under the tension of the rope, preventing relative slippage between the rope and the mooring rings. This avoids surface abrasion and fiber cutting, thus ensuring the surface integrity and tensile strength of the rope.

[0006] Furthermore, by using multiple rubber rings and mooring rings, if the surface of a mooring ring corrodes, the corroded mooring ring can be removed simply by unscrewing the bolts between the pile cap and the first or second pile body, and then a new mooring ring can be replaced. This avoids the problem of surface abrasion or fiber cutting caused by surface corrosion of the mooring ring, thus ensuring the tensile strength of the rope. Moreover, only the corroded mooring ring needs to be replaced, without replacing the entire mooring pile, reducing maintenance costs.

[0007] Preferably, the rubber ring has multiple deformation holes arranged in a circular array along the axis of the rubber ring, and all the deformation holes penetrate the upper and lower sides of the rubber ring. Each deformation hole includes a first arc surface and a second arc surface. The first arc surface faces the pile body, and the second arc surface faces the mooring ring. The first arc surface and the second arc surface are connected, and the first arc surface is located outside the second arc surface. The position where the first arc surface and the second arc surface are connected is provided with a rounded transition angle.

[0008] In practical applications, when a ship sways due to waves or tides, the tension in the rope increases instantaneously. At this time, the rubber ring, through the elastic deformation of the deformation hole, can quickly absorb and disperse this additional tension, preventing the rope from breaking due to the sudden increase in tension. Simultaneously, the design of the deformation hole makes the rubber ring more flexible during torsional deformation, effectively preventing relative slippage between the rope and the mooring ring, further protecting the integrity of the rope. By setting deformation holes within the rubber ring, it can deform more evenly when subjected to rope tension. With the first arc-shaped surface facing the pile and the second arc-shaped surface facing the mooring ring, this structural design allows the rubber ring to effectively buffer forces from different directions through compression or expansion of the deformation hole, further protecting the rope from damage. The rounded transition angle reduces stress concentration and improves the service life of the rubber ring.

[0009] Preferably, each of the mooring rings has a limiting flange on both its upper and lower end faces. The limiting flange is coaxially arranged with the mooring ring. The diameter of the rope is D, and the radii of the mooring ring and the limiting flange are R1 and R2, respectively, where 1.2D≤R2-R1≤1.5D.

[0010] During mooring, the ropes need to be wound around piles one and two. The limiting flange prevents surface friction between the upper and lower ropes during winding. As the ship rolls, the ropes move up and down with it. If there is surface contact between the ropes, surface friction will occur between the upper and lower ropes during the rolling motion, which will cause accelerated wear. The limiting flange restricts the range of motion of the ropes, keeping them within the effective working area of ​​the mooring ring. This prevents the ropes from rubbing or colliding with other components due to excessive deviation, thus ensuring the safe use of the ropes and the normal operation of the mooring piles.

[0011] Furthermore, designing the size of the limiting flange to 1.2D≤R2-R1≤1.5D can effectively prevent the rope from slipping out of the limiting flange's range of action when it becomes loose. The large range of action of the limiting flange also makes it easier for crew members to wrap the rope around the mooring bollard.

[0012] Preferably, the mooring ring includes a type I mooring ring and a type II mooring ring. Only one type I mooring ring is provided on each of the No. 1 and No. 2 piles, and the type I mooring ring is located at the bottom. The upper end surface of the limiting flange on the lower side of the type I mooring ring is a plane, and the lower end surface of the limiting flange on the upper side of the type I mooring ring is provided with a type I rope guide surface. The upper end surface of the limiting flange on the lower side of the type II mooring ring is provided with a type II rope guide surface, and the lower end surface of the limiting flange on the upper side of the type II mooring ring is provided with a type III rope guide surface. The type I, type II, and type III rope guide surfaces are all inclined surfaces with the same inclination. The type I and type III rope guide surfaces are both inclined downwards, and the type I and type III rope guide surfaces are parallel. The type II rope guide surface is inclined upwards.

[0013] When the crew winds the ropes onto the mooring bollards, the planar structure of the lower limiting flange of the Type I mooring ring facilitates the initial placement and positioning of the ropes, while the inclined design of the Type I rope guide surface guides the ropes smoothly upwards to the Type II mooring rings. The Type II and Type III rope guide surfaces on the upper and lower sides of the Type II mooring rings further control the direction of the ropes, ensuring that the ropes are tightly and orderly wound around each mooring ring, avoiding confusion and crossing of the ropes during the winding process. This not only improves the efficiency of mooring operations but also reduces safety hazards caused by improper rope placement. At the same time, the inclined rope guide surface can also disperse the local pressure of the ropes on the mooring rings to a certain extent, extending the service life of the mooring rings.

[0014] Preferably, rubber pads are provided on the upper end face of the limiting flange on the lower side of the type I mooring ring, the type I rope guide surface, the type II rope guide surface, and the type III rope guide surface. The rubber pads are fixedly connected to the corresponding type I mooring ring or type II mooring ring, and the surface of the rubber pads is provided with mesh-like patterned protrusions.

[0015] The rubber pad further enhances the friction between the mooring ring and the rope, ensuring that the rope is stably fixed to the mooring ring during mooring and is less prone to slippage or detachment. Simultaneously, the textured, raised design increases the surface roughness of the rubber pad. This roughness not only improves the coefficient of friction but also disperses the localized pressure exerted by the rope on the rubber pad to some extent, preventing wear or damage caused by concentrated pressure. Furthermore, the rubber pad acts as a buffer; when the rope experiences a sudden increase in tension due to ship movement, the rubber pad absorbs some of the impact force, protecting the mooring ring and rope from damage. This not only improves the practicality and reliability of the mooring bollard but also extends its service life.

[0016] Preferably, a copper alloy layer is provided on the outer side wall of both the No. 1 pile body and the No. 2 pile body, and the copper alloy layer completely covers the side wall of the No. 1 pile body or the No. 2 pile body. A sleeve is coaxially provided on the inner side wall of the rubber ring, and the rubber ring and the sleeve are fixedly connected. The sleeve and the copper alloy layer are slidably connected.

[0017] The copper alloy layer effectively improves the corrosion resistance of piles No. 1 and No. 2. In the high-salt and high-humidity environment of the coast, the copper alloy layer can isolate seawater and salty air from direct contact with the pile substrate, thereby slowing down the oxidation and corrosion rate of the pile and extending the service life of the pile.

[0018] Furthermore, the smooth surface of the copper alloy layer facilitates the smooth sliding of the sleeve, reducing frictional resistance and ensuring the rubber ring can move flexibly up and down to adapt to changes in cable tension under different working conditions. This effectively buffers changes in cable tension and ensures the cable's service life. The fixed connection between the sleeve and the rubber ring ensures that the rubber ring will not shift relative to the sleeve during deformation, thus ensuring the stability and reliability of the entire bollard structure.

[0019] Preferably, the sleeve is provided with installation guide surfaces on both the upper and lower sides, and the bottom of the No. 1 pile body and the No. 2 pile body are provided with installation inclined surfaces, and the inclination of the installation inclined surfaces is the same as that of the installation guide surfaces.

[0020] During installation, the coordinated design of the installation guide surface and the installation ramp plays a crucial role. The installation guide surface provides clear guidance for the installation of the sleeve, enabling the sleeve to be accurately and quickly positioned at the predetermined location on piles No. 1 and No. 2, ensuring the installation direction of the Type I and Type II mooring rings on piles No. 1 and No. 2. This, in turn, ensures the orientation and position of the Type I, Type II, and Type III rope guide surfaces, guaranteeing the accurate routing of the ropes and preventing confusion and crossing of the ropes during the winding process. In addition, the identical inclination design also allows the sleeve to work better with the rubber rings when subjected to external forces, jointly resisting the tension generated by the ship's swaying, further protecting the ropes and mooring piles from damage.

[0021] Preferably, a compensation ring is provided between the Type I mooring ring and the Type II mooring ring, and between adjacent Type II mooring rings, and the compensation ring is made of elastic rubber.

[0022] The compensating ring, made of elastic rubber, has good elastic deformation capability. When the cable experiences tension fluctuations due to ship swaying or tidal changes, the compensating ring can absorb some of the energy through its own elastic deformation, effectively reducing the impact force on the cable and preventing the cable from breaking due to instantaneous overload.

[0023] Furthermore, the compensation ring fills the gaps between the Type I and Type II tethering rings, as well as between adjacent Type II tethering rings. This structure not only ensures a continuous and stable contact surface for the rope during winding, reducing localized wear caused by gaps, but also disperses the concentrated pressure of the rope on the tethering ring through elastic support, extending the service life of the tethering ring.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention provides rubber rings and mooring rings on the outer walls of piles No. 1 and No. 2. When small areas of the mooring ring surface corrode, the tension on the rope increases when the ship slides, increasing the friction between the mooring ring and the rope. The rubber ring undergoes torsional deformation under the tension of the rope, preventing relative sliding between the rope and the mooring ring, avoiding surface abrasion and fiber cutting of the rope, thus ensuring the surface integrity of the rope and its tensile strength.

[0025] 2. This invention provides a deformation hole inside the rubber ring. The elastic deformation of the rubber ring through the deformation hole can quickly absorb and disperse the extra tension generated by the slippage of the rope, preventing the rope from breaking due to the sudden increase in tension. At the same time, the design of the deformation hole also makes the rubber ring more flexible when tortuous, effectively avoiding relative slippage between the rope and the mooring ring, and further protecting the integrity of the rope.

[0026] 3. By setting different rope guide surfaces on the mooring ring, the present invention avoids the confusion and crossing of ropes during the winding process, which not only improves the efficiency of mooring operations, but also reduces safety hazards caused by improper rope arrangement. In addition, the inclined rope guide surfaces can also disperse the local pressure of the ropes on the mooring ring to a certain extent, thus extending the service life of the mooring ring.

The position where the first arc surface 5011 and the second arc surface 5012 are connected is provided with a rounded transition angle 5013. A copper alloy layer 9 is provided on the outer side wall of both pile body 2 and pile body 3. The copper alloy layer 9 completely covers the side wall of pile body 2 or pile body 3. A sleeve 10 is coaxially provided on the inner side wall of the rubber ring 5. The rubber ring 5 and the sleeve 10 are fixedly connected. The sleeve 10 and the copper alloy layer 9 are slidably connected. The upper and lower sides of the sleeve 10 are provided with installation guide surfaces 1001. The bottom of pile body 2 and pile body 3 are provided with installation inclined surfaces 201. The inclination of the installation inclined surfaces 201 is the same as that of the installation guide surfaces 1001.

[0031] Please see Figure 1 , Figures 5 to 8Each mooring ring 6 has a limiting flange 7 on both its upper and lower ends. The limiting flange 7 is coaxially arranged with the mooring ring 6. The diameter of the rope is 50mm, the diameter of the mooring ring 6 is 240mm, and the diameter of the limiting flange 7 is 380mm. The mooring ring 6 includes a type I mooring ring 601 and a type II mooring ring 602. Only one type I mooring ring 601 is provided on each of the No. 1 pile body 2 and the No. 2 pile body 3, and the type I mooring ring 601 is located on the bottom side. The upper end surface of the limiting flange 7 on the lower side of the type I mooring ring 601 is flat, and the lower end surface of the limiting flange 7 on the upper side of the type I mooring ring 601 is provided with a type I rope guide surface 701. The upper end surface of the limiting flange 7 on the lower side of the type II mooring ring 602 is provided with a type II rope guide surface 702, and the lower end surface of the limiting flange 7 on the upper side of the type II mooring ring 602 is provided with a type III rope guide surface 703. Guide surface 701, Type II rope guide surface 702, and Type III rope guide surface 703 are all inclined surfaces with the same inclination. Type I rope guide surface 701 and Type III rope guide surface 703 are both inclined downwards, and Type I rope guide surface 701 and Type III rope guide surface 703 are parallel. Type II rope guide surface 702 is inclined upwards. Rubber pads 8 are provided on the upper end face of the limiting flange 7 on the lower side of Type I mooring ring 601, Type I rope guide surface 701, Type II rope guide surface 702, and Type III rope guide surface 703. The rubber pads 8 are fixedly connected to the corresponding Type I mooring ring 601 or Type II mooring ring 602, and the surface of the rubber pads 8 is provided with a mesh-like patterned protrusion. Compensation rings 11 are provided between Type I mooring ring 601 and Type II mooring ring 602, and between adjacent Type II mooring rings 602. The compensation rings 11 are made of elastic rubber.

[0032] Working principle: When the vessel needs to be moored, the crew sequentially winds the ropes around the mooring rings 6 on pile 1 (2) and pile 2 (3). During this winding process, the planar structure of the lower limiting flange 7 of the type I mooring ring 601 provides a stable initial placement surface for the ropes, facilitating rapid positioning. The inclined design of the type I rope guide surface 701 guides the ropes smoothly upwards to the type II mooring ring 602. The type II rope guide surfaces 702 and type III rope guide surfaces 703 on the upper and lower sides of the type II mooring ring 602 further control the direction of the ropes, ensuring that the ropes are tightly and orderly wound around each mooring ring 6, avoiding rope tangling and crossing, improving mooring efficiency, and reducing safety hazards. When the ship's swaying or tidal changes cause fluctuations in rope tension, the deformation holes 501 inside the rubber ring 5 quickly absorb and disperse the additional tension generated by the ropes through elastic deformation. The circular arc transition angle 5013 set at the junction of the first arc surface 5011 and the second arc surface 5012 of the deformation hole 501 effectively reduces stress concentration, makes the torsional deformation of the rubber ring 5 more flexible, avoids relative slippage between the rope and the tethering ring 6, ensures the integrity of the rope surface, and maintains the tensile strength of the rope. At the same time, the compensation ring 11, with its elastic rubber material, undergoes elastic deformation when the rope tension changes, absorbs some energy, reduces the impact force on the rope, and prevents the rope from breaking due to instantaneous overload. The compensation ring 11 also fills the gaps between the first type tethering ring 601 and the second type tethering ring 602, as well as between adjacent second type tethering rings 602, so that the rope maintains a continuous and stable contact surface during winding, reduces local wear of the rope, and disperses the concentrated pressure of the rope on the tethering ring 6 through elastic support, thus extending the service life of the tethering ring 6. Furthermore, the sliding connection between the sleeve 10 and the copper alloy layer 9, and the design of the mounting guide surfaces 1001 on the upper and lower sides of the sleeve 10 and the mounting inclined surfaces 201 at the bottom of the first pile body 2 and the second pile body 3, ensure that the rubber ring 5 can move flexibly up and down to adapt to the changes in cable tension under different working conditions. During installation, the mounting guide surfaces 1001 provide clear guidance for the sleeve 10, enabling the sleeve 10 to be accurately and quickly positioned to the predetermined position, ensuring the accuracy of the installation direction of the mooring ring 6 and the direction of the cable.

[0033] The type I rope guide surface 701, type II rope guide surface 702, and type III rope guide surface 703 provided on the mooring ring 6, along with the rubber pad 8 provided on the limiting flange 7, further enhance the friction between the mooring ring 6 and the rope, ensuring stable fixation of the rope. The mesh-like raised texture on the surface of the rubber pad 8 increases roughness, improves the coefficient of friction, disperses the local pressure of the rope on the rubber pad 8, prevents wear or damage to the rubber pad 8, and also acts as a buffer, protecting the mooring ring 6 and the rope from damage.
