Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mooring bitts, in particular to a mooring bitt for ships. BACKGROUND

[0002] The mooring bitt for ships is usually made of cast iron or cast steel, and a layer of paint is coated on the surface of the mooring bitt during production to prevent rust and improve the smoothness of the surface. However, when used in a coastal environment, if the damaged paint surface of the mooring bitt cannot be repainted in time to ensure the smoothness of the surface of the mooring bitt, seawater and salty air will cause corrosion of the mooring bitt. Due to the presence of oxides, the surface of the mooring bitt becomes rough and has sharp oxide scales. During mooring, the movement of the ship body causes the rope to slide on the surface of the mooring bitt. At this time, the surface of the mooring bitt acts like a file on the surface of the rope, which easily causes the surface of the rope to be abraded and the fibers to be cut, thereby reducing the tensile strength of the rope and shortening the service life of the rope. The rope is more likely to be broken. At the same time, the conventional mooring bitt is usually integrally cast, and it is not easy to repair the surface of the mooring bitt after rust occurs on the surface of the mooring bitt, and the cost of replacing a whole mooring bitt is too high. SUMMARY

[0003] The purpose of the present application is to provide a mooring bitt for ships to solve the problem that the oxidation of the surface of the mooring bitt in a coastal environment easily causes the surface of the rope to be abraded and the fibers to be cut, thereby reducing the tensile strength of the rope, and to solve the problem that the integrally cast mooring bitt is not easy to maintain and the cost of replacement is high.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical scheme:

[0005] A mooring bitt for ships, comprising a base, a first pile body, a second pile body and two pile caps, the first pile body and the second pile body are symmetrically arranged on the base, and the first pile body and the second pile body are both vertically arranged, and the two pile caps are coaxially arranged at the top ends of the first pile body and the second pile body, respectively. Specifically, the pile cap is connected with the first pile body and the second pile body through bolts, at least three rubber rings are coaxially arranged on the first pile body and the second pile body, the rubber ring is in sliding connection with the first pile body and the second pile body, and an outer wall of each rubber ring is coaxially provided with a mooring ring, the mooring ring is fixedly connected with the rubber ring, and the height of the mooring ring and the rubber ring is the same.

[0006] The rubber ring and the mooring ring are arranged on the outer side wall of the first pile body and the second pile body, and when mooring is performed, the rope is wound around the plurality of mooring rings, and when the ship shakes due to the ebb and flow of the tide, waves or human influence, the tension of the rope increases, the rubber ring is compressed and deformed, the deformation of the rubber ring provides a buffer and compensation for the rope, prevents the rope from being broken, and improves the safety of the ship when mooring.

[0007] Further, the plurality of rubber rings and mooring rings are adopted, after the surface of a certain mooring ring is rusted, only the bolt between the pile cap and the first pile body or the second pile body is removed, the rusted mooring ring is removed, and a new mooring ring is replaced, so that the problem of surface abrasion or fiber cutting of the rope caused by rust on the surface of the mooring ring is avoided, the tensile strength of the rope is ensured, only the rusted mooring ring needs to be replaced, and the entire mooring pile does not need to be replaced, so that the maintenance cost is reduced.

[0008] Preferably, a plurality of deformation holes are arranged in the rubber ring, the plurality of deformation holes are arranged in an annular array along the axis of the rubber ring, and the plurality of deformation holes penetrate the upper and lower sides of the rubber ring, the deformation hole comprises a first arc surface and a second arc surface, the first arc surface faces the pile body, 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, and a circular arc transition corner is arranged at the position where the first arc surface and the second arc surface are connected.

[0009] In actual application, when the ship shakes due to waves or tides, the tension of the rope instantaneously increases, at this time, the rubber ring can rapidly absorb and disperse the part of the additional tension through the elastic deformation of the deformation hole, so as to prevent the rope from being broken due to the sudden increase of the tension, and the design of the deformation hole also makes the rubber ring more flexible when it is twisted and deformed, effectively avoids the relative sliding between the rope and the mooring ring, and further protects the integrity of the rope. By arranging the deformation hole in the rubber hole, the rubber ring can be deformed more uniformly when it is subjected to the tension of the rope, the first arc surface faces the pile body, and the second arc surface faces the mooring ring, so that the rubber ring can effectively buffer through the compression or expansion of the deformation hole when it is subjected to forces in different directions, so as to further protect the rope from being damaged, and the circular arc transition corner reduces stress concentration and improves the service life of the rubber ring.

[0010] Preferably, the upper and lower end faces of each of the mooring rings are provided with limiting flanges, the limiting flanges are coaxially arranged with the mooring ring, the diameter of the rope is D, the radii of the mooring ring and the limiting flange are R1 and R2 respectively, and 1.2D≤R2-R1≤1.5D.

[0011] When mooring, the rope needs to be wound around the first pile body and the second pile body, and the arrangement of the limiting flange prevents surface friction between the upper and lower ropes during winding. Since the rope will move up and down with the ship when the ship is swaying, if there is surface contact between the ropes, surface friction will occur between the upper and lower ropes during the movement of the rope, thereby causing the problem of accelerated wear of the rope. By limiting the movement range of the rope with the limiting flange, the rope is always kept within the effective action range of the mooring ring, avoiding friction or collision with other components due to excessive deviation of the rope, thereby ensuring the safe use of the rope and the normal operation of the mooring pile.

[0012] Further, the size of the limiting flange is designed as 1.2D≤R2-R1≤1.5D, which can effectively prevent the rope from moving out of the action range of the limiting flange when the rope is loose, and the action range of the limiting flange is large, which is beneficial to the crew to wind the rope on the mooring pile.

[0013] Preferably, the mooring ring includes a first mooring ring and a second mooring ring, only one first mooring ring is arranged on the first pile body and the second pile body, and the first mooring ring is located at the bottom side, the upper end face of the limiting flange on the lower side of the first mooring ring is a flat surface, the lower end face of the limiting flange on the upper side of the first mooring ring is provided with a first rope guide surface, the upper end face of the limiting flange on the lower side of the second mooring ring is provided with a second rope guide surface, the lower end face of the limiting flange on the upper side of the second mooring ring is provided with a third rope guide surface, the first rope guide surface, the second rope guide surface and the third rope guide surface are all inclined surfaces with the same inclination, the first rope guide surface and the third rope guide surface are both inclined downward, and the first rope guide surface is parallel to the third rope guide surface, and the second rope guide surface is inclined upward.

[0014] When the crew winds the rope on the mooring pile, the flat structure of the limiting flange on the lower side of the first mooring ring facilitates the initial placement and positioning of the rope, and the inclined design of the first rope guide surface guides the rope to smoothly transition upward to the second mooring ring; the second rope guide surface and the third rope guide surface on the upper and lower sides of the second mooring ring further control the direction of the rope, ensuring that the rope can be tightly and orderly wound on each mooring ring, avoiding the confusion and crossing of the rope during the winding process, not only improving the efficiency of the mooring operation, but also reducing the safety hazards caused by improper arrangement of the rope. At the same time, the inclined rope guide surface can also disperse the local pressure of the rope on the mooring ring to some extent, prolonging the service life of the mooring ring.

[0015] Preferably, the upper end surface of the limiting flange of the lower side of the first type of mooring ring, the first type of rope guide surface, the second type of rope guide surface and the third type of rope guide surface are all provided with rubber pads, which are fixedly connected with the corresponding first type of mooring ring or second type of mooring ring, and the surface of the rubber pad is provided with a mesh patterned raised surface.

[0016] The setting of the rubber pad further enhances the friction between the mooring ring and the rope, ensuring that the rope can be stably fixed on the mooring ring during mooring, and is not easy to slip or fall off; at the same time, the mesh patterned raised surface design increases the roughness of the surface of the rubber pad, which not only increases the friction coefficient, but also to a certain extent, disperses the local pressure of the rope on the rubber pad, avoiding the wear and damage of the rubber pad caused by pressure concentration; in addition, the rubber pad can also play a buffering role, when the rope produces instantaneous increased tension due to the sway of the ship, the rubber pad can absorb part of the impact force, protecting the mooring ring and the rope from damage, not only improving the practicability and reliability of the mooring pile, but also prolonging the service life of the mooring pile.

[0017] Preferably, the outer side wall of the first pile body and the second pile body is provided with a copper alloy layer, the copper alloy layer completely covers the side wall of the first pile body or the second pile body, the inner side wall of the rubber ring is coaxially provided with a sleeve, the rubber ring is fixedly connected with the sleeve, and the sleeve and the copper alloy layer are in sliding connection.

[0018] The setting of the copper alloy layer effectively improves the corrosion resistance of the first pile body and the second pile body. In the high-salt and high-humidity environment of the coast, the copper alloy layer can isolate the direct contact of seawater and salty air with the pile body base material, thereby slowing down the oxidation corrosion speed of the pile body and prolonging the service life of the pile body.

[0019] Further, the surface of the copper alloy layer is smooth, which is conducive to the smooth sliding of the sleeve on its surface, reducing the resistance generated by friction, ensuring that the rubber ring can move up and down flexibly to adapt to the tension changes of the rope under different working conditions, thereby effectively providing buffer for the tension changes of the rope, ensuring the service life of the rope. The fixed connection mode of the sleeve and the rubber ring ensures that the rubber ring will not relatively displace with the sleeve during deformation, thereby ensuring the stability and reliability of the entire mooring pile structure.

[0020] Preferably, the upper and lower sides of the sleeve are provided with mounting guide surfaces, and the bottom of the first pile body and the second pile body is provided with a mounting inclined surface, and the inclination of the mounting inclined surface is the same as that of the mounting guide surface.

[0021] During the installation process, the cooperation of the installation guide surface and the installation inclined surface plays a key role, the installation guide surface provides clear guidance for the installation of the sleeve, so that the sleeve can be accurately and quickly positioned to the predetermined position on the first pile body and the second pile body, the installation direction of the first type mooring ring and the second type mooring ring on the first pile body and the second pile body is ensured, so that the directions and positions of the first type rope guide surface, the second type guide surface and the third type guide surface are ensured, the accurate direction of the rope is ensured, and the confusion and intersection of the rope during the winding process are avoided; in addition, the same inclination also enables the sleeve to work better with the rubber ring when subjected to external force, and resist the tension caused by the ship sway together, further protecting the rope and the mooring pile from damage.

[0022] Preferably, the first type mooring ring and the second type mooring ring, and the adjacent second type mooring rings are all provided with compensation rings made of elastic rubber material.

[0023] The compensation ring made of elastic rubber material has good elastic deformation capacity, and when the rope is subjected to tension fluctuation due to ship sway or tidal changes, the compensation ring can absorb part of the energy through its elastic deformation, effectively reducing the impact force on the rope and preventing the rope from breaking due to instantaneous overload.

[0024] Further, the compensation ring fills the gap between the first type mooring ring and the second type mooring ring, and between the adjacent second type mooring rings, which not only makes the rope maintain continuous and stable contact during winding, reducing local wear of the rope caused by the gap, but also disperses the concentrated pressure of the rope on the mooring ring through elastic support, prolonging the service life of the mooring ring.

[0025] Compared with the prior art, the present application has the following advantages:

[0026] 1. By arranging the rubber ring and the mooring ring on the outer side wall of the first pile body and the second pile body, when the surface of the mooring ring is slightly corroded, the tension on the rope increases when the ship slides, the friction between the mooring ring and the rope increases, the rubber ring twists and deforms under the tension of the rope, avoiding relative sliding between the rope and the mooring ring, and preventing the surface of the rope from being abraded and the fibers from being cut, thereby ensuring the surface integrity of the rope and the tensile strength of the rope.

[0027] 2. By arranging the deformation hole in the rubber ring, the rubber ring can quickly absorb and disperse the additional tension of the rope caused by the ship sliding through the elastic deformation of the deformation hole, preventing the rope from breaking due to sudden increase in tension; at the same time, the design of the deformation hole also makes the rubber ring more flexible when it twists and deforms, effectively avoiding the relative sliding between the rope and the mooring ring, and further protecting the integrity of the rope.

[0028] 3、The present application sets different rope guiding surfaces on the mooring ring, avoids the confusion and intersection of the ropes during the arrangement process, improves the efficiency of the mooring operation, reduces the safety hazards caused by improper arrangement of the ropes, and the inclined rope guiding surfaces can also disperse the local pressure of the ropes on the mooring ring to some extent, prolonging the service life of the mooring ring.

[0042] Working principle:

[0043] When the ship needs to be moored, the crew will place the rope on each mooring ring 6 on the first pile body 2 and the second pile body 3 in turn. During the placement process, the planar structure of the lower side limiting flange 7 of the first mooring ring 601 provides a stable initial placement surface for the rope, facilitating quick positioning of the rope; the inclined design of the first rope guide surface 701 guides the rope to smoothly transition upward to the second mooring ring 602, and the second rope guide surface 702 and the third rope guide surface 703 on the upper and lower sides of the second mooring ring 602 further control the direction of the rope, allowing the rope to be placed tightly and orderly on each mooring ring 6, avoiding rope confusion and intersection, improving mooring efficiency, and reducing safety hazards. When the ship sways or the tide changes, causing the rope tension to fluctuate, the deformation hole 501 in the rubber ring 5 rapidly absorbs and disperses the additional tension generated by the rope through elastic deformation. The round transition corner 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, making the rubber ring 5 twist and deform more flexible, avoiding relative sliding between the rope and the mooring ring 6, ensuring the integrity of the rope surface, and maintaining the tensile strength of the rope. At the same time, the compensating ring 11, due to its elastic rubber material, elastically deforms when the rope tension changes, absorbs part of the energy, slows down the impact force on the rope, and prevents the rope from breaking due to instantaneous overload. The compensating ring 11 also fills the gap between the first mooring ring 601 and the second mooring ring 602, as well as between adjacent second mooring rings 602, allowing the rope to maintain a continuous and stable contact surface during placement, reducing local wear of the rope, and dispersing the concentrated pressure of the rope on the mooring ring 6 through elastic support, prolonging the service life of the mooring ring 6. In addition, the sliding connection of the sleeve 10 and the copper alloy layer 9, as well as the cooperation design of the guide surface 1001 installed on the upper and lower sides of the sleeve 10 and the inclined surface 201 installed at the bottom of the first pile body 2 and the second pile body 3, ensure that the rubber ring 5 can move up and down flexibly to adapt to the changes in rope tension under different working conditions. During installation, the installation guide surface 1001 provides a clear guide for the sleeve 10, allowing 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 rope.

[0044] The first rope guide surface 701, the second rope guide surface 702, and the third rope guide surface 703 provided on the mooring ring 6, as well as the rubber pad 8 provided on the limiting flange 7, further enhance the friction between the mooring ring 6 and the rope, ensuring the stable fixation of the rope. The net-like pattern protrusions on the surface of the rubber pad 8 increase the roughness, improve the friction coefficient, disperse the local pressure of the rope on the rubber pad 8, avoid the wear or damage of the rubber pad 8, and at the same time, serve as a buffer to protect the mooring ring 6 and the rope from damage.
