Description

Technical Field

[0001] The present invention relates to the technical field of ship rubber fenders, and particularly to a rubber fender system for a fully rotating ocean tugboat. Background Art

[0002] A fully rotating ocean tugboat is a ship specifically used for operations such as towing and pulling in the ocean environment. The remarkable feature of a fully rotating ocean tugboat is the use of a fully rotating thruster, which can rotate flexibly within a range of 360 degrees, enabling the ship to achieve precise control in a narrow space. Generally, it has a strong hull structure that can withstand the huge pulling force and wave impact during towing. It is mainly used to assist large ships in entering and leaving ports, towing ships at sea, shifting and installing offshore platforms, rescuing distressed ships, etc.

[0003] However, in the prior art, the selection of fenders used by ocean tugboats is relatively single. Only W-shaped rubber fenders or only tires are used as fenders. However, when a fully rotating ocean tugboat operates, it rotates frequently. If a rubber fender with a single structure is used, when approaching the ship to be towed, the collision angle between the two is uncertain, and there will be a situation where the protection range is limited. For example, when colliding obliquely from the side, the side wings of the W shape and a single tire cannot be compressed as expected, resulting in the collision energy not being fully dispersed and absorbed, causing the ship to receive a greater impact force, and some areas of the ocean tugboat cannot be fully protected, increasing the possibility of ship damage.

[0004] Therefore, we propose a rubber fender system for a fully rotating ocean tugboat to solve the problems raised above. Summary of the Invention

[0005] The purpose of the present invention is to provide a rubber fender system for a fully rotating ocean tugboat to solve the problem of insufficient protection of the ship caused by the single structure of the existing fenders used by ocean tugboats as mentioned in the above background art.

[0006] To achieve the above object, the present invention provides the following technical solution: a full-rotation marine tug rubber fender system, including a protection component and a rebound component. A plurality of the protection components and the rebound components are provided. The protection component includes a bent fender, which absorbs energy and buffers when a ship collides with the marine tug, and has an elastic thrust between the ship and the marine tug. A plurality of hexagonal grooves are provided at the top of the bent fender; the rebound component includes a cylindrical fender. An air cavity is provided at the top of the cylindrical fender.

A spring protection sleeve is sleeved outside each protection spring, and the spring protection sleeve is made of fiber-reinforced composite material.

[0007] Preferably, the protection component further includes a plurality of support plates. Each support plate is fixedly installed between the outer surfaces of adjacent two bent fenders. The outer surfaces of the other sides of the two separated bent fenders are fixedly connected with mounting plates. The support plates and the mounting plates are both used to realize the connection of the whole rubber fender.

[0008] Preferably, two first through holes are provided at one end of each support plate, and a first mounting hole is provided at one end of each mounting plate. A first fastening chain is movably connected between the plurality of first through holes and the two first mounting holes. The first fastening chain is threaded in a wave form, and both ends of the first fastening chain are fixedly connected with first mounting rings.

[0009] Preferably, two second through holes are provided at the other end of each support plate, and a second mounting hole is provided at the other end of each mounting plate. A second fastening chain is movably connected between the plurality of second through holes and the two second mounting holes. Both ends of the second fastening chain are fixedly connected with second mounting rings. The two first mounting rings and the two second mounting rings are both used to be fixed to the side plate of the marine tug.

[0010] Preferably, each cylindrical fender is fixedly connected between the outer surfaces of adjacent two bent fenders, and the plurality of cylindrical fenders and the plurality of bent fenders form a whole.

[0011] Preferably, the plurality of buffer cartridges provided inside each cylindrical fender are taken as a group. A group of connecting elastic pieces are fixedly connected between the outer surfaces of a group of buffer cartridges. Both sides of a group of connecting elastic pieces are fixedly connected with the inner wall of the cylindrical fender and the outer surface of the buffer inner ring respectively.

[0012] Preferably, a fixing rod is provided at the center inside the buffer inner ring, and the cross section of the fixing rod is in a regular hexagon shape.

[0013] Preferably, a plurality of the protective springs are evenly arranged on the outer surface of the fixed rod on six sides. The plurality of protective springs are evenly divided into twelve groups. A reinforcing long plate is fixedly connected between one ends of each group of protective springs. The plurality of reinforcing long plates are fixedly installed on the inner wall of the buffer inner ring.

[0014] Preferably, a plurality of anti-slip strips are fixedly connected to the outer surface of each cylindrical fender, and the anti-slip strips are used to increase the resistance during ship collision.

[0015] Preferably, the support plate, the bent fender, the mounting plate, the cylindrical fender, the anti-slip strip, the buffer cartridge, the connecting spring piece and the buffer inner ring are made of the same material. Pyrolytic carbon black particles are added to the rubber material to improve the aging resistance and wear resistance of the rubber. The rubber variety is natural rubber, and a plasticizer is added to the rubber material to reduce the interaction force between rubber molecular chains and increase the flexibility and mobility of molecular chains.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. During use, the W-shaped structure formed by connecting a plurality of bent fenders enables the rubber fender to have multiple buffering stages, effectively absorbing and dispersing the energy generated by ship collision in stages, reducing the impact force on the hull. The cylindrical structure of the cylindrical fender can make the buffering performance more uniform in all directions. The multiple buffer cartridges and connecting spring pieces designed by superposition can increase the number and complexity of buffering levels. When the protective spring is compressed by collision, it can provide an additional elastic restoring force for the rubber fender, helping to push the ship away from the hull of the tugboat after ship collision, reducing the contact time and friction between the ship and the hull, and reducing the possibility of hull damage. In addition, the spring protection sleeve made of fiber-reinforced composite material can prevent the protective spring from breaking and deforming under the erosion of seawater, thus solving the problem of poor protection effect caused by the single structure of the existing rubber fender.

[0017] 2. During use, secondary energy absorption is achieved through the cylindrical fender and the bent fender. The cylindrical fender and the bent fender play a buffering and protecting role when rebounding. During side collision, the whole rubber fender will be horizontally extruded, and after release, it will rebound to its original position, avoiding damage to the hull caused by the offset of the protection point during collision. The hexagonal groove opened inside the bent fender can generate more deformation and displacement when being collided, and absorb and dissipate the collision energy through the compression, twisting, etc. of the notch, playing a role in protecting the hull structure and equipment.

[0018] 3. During use, cracked carbon black particles are added to conventional rubber materials, making the rubber fender less likely to be damaged when subjected to collisions and friction, extending its service life. Carbon black has a certain ultraviolet absorption capacity and antioxidant effect, which can improve the aging resistance of rubber, slow down the performance degradation of rubber caused by factors such as light and oxidation during long-term use, and maintain the performance stability of the rubber fender. In addition, by adding plasticizers to the rubber material, the force between rubber molecular chains can be reduced, the flexibility and mobility of molecular chains can be increased, thereby reducing the glass transition temperature of rubber and improving its low-temperature performance, enabling the rubber fender of the fully rotating ocean tugboat to maintain good elasticity even at low temperatures and playing a protective role for the ocean tugboat and ships.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Example 1: Refer to Figures 1-9As shown in the figure, the present invention provides a technical solution: a full-rotation marine tug rubber fender system, which includes a protection component 1 and a resilience component 2. A plurality of protection components 1 and resilience components 2 are provided. The protection component 1 includes a bent fender 102. The bent fender 102 will absorb energy and buffer when a ship collides with the marine tug, and it has an elastic thrust between the ship and the marine tug. A plurality of hexagonal grooves 103 are opened at the top of the bent fender 102; the resilience component 2 includes a cylindrical fender 201. An air cavity 203 is opened at the top of the cylindrical fender 201. A plurality of buffer cartridges 204 are provided inside the air cavity 203, and the plurality of buffer cartridges 204 are used in combination to increase the resilience and buffering performance. A buffer inner ring 206 is provided on the inner wall of the air cavity 203, and the buffer inner ring 206 supports the stacked buffer cartridges 204. A plurality of protection springs 209 are provided inside the buffer inner ring 206. A spring protection sleeve 210 is sleeved outside each protection spring 209, and the spring protection sleeve 210 is made of fiber-reinforced composite material. Each cylindrical fender 201 is fixedly connected between the outer surfaces of two adjacent bent fenders 102, and the plurality of cylindrical fenders 201 and the plurality of bent fenders 102 form an integral body. The plurality of buffer cartridges 204 provided inside each cylindrical fender 201 are taken as a group. A group of connecting elastic sheets 205 are fixedly connected between the outer surfaces of a group of buffer cartridges 204. Two sides of a group of connecting elastic sheets 205 are respectively fixedly connected to the inner wall of the cylindrical fender 201 and the outer surface of the buffer inner ring 206. A fixing rod 207 is provided at the center inside the buffer inner ring 206, and the cross section of the fixing rod 207 is in a regular hexagonal shape. The plurality of protection springs 209 are evenly arranged on the six outer surfaces of the fixing rod 207. The plurality of protection springs 209 are evenly divided into twelve groups. A reinforcing long plate 208 is fixedly connected between one ends of each group of protection springs 209. The plurality of reinforcing long plates 208 are fixedly installed on the inner wall of the buffer inner ring 206. A plurality of anti-slip strips 202 are fixedly connected to the outer surface of each cylindrical fender 201, and the anti-slip strips 202 are used to increase the resistance during ship collision.

[0023] In this embodiment, during use, a plurality of bent fenders 102 are connected by a support plate 101 to form an integral W-shaped structure. The W-shaped structure enables the rubber fender to have multiple buffering stages. When impacted, first, the wings of the W shape come into contact and undergo elastic deformation, absorbing a part of the energy. Then, the middle part is further compressed, effectively absorbing and dispersing the energy generated by ship collisions in stages, reducing the impact force on the hull. A cylindrical fender 201 is fixed between the two bent fenders 102. The cylindrical structure of the cylindrical fender 201 has relatively uniform buffering performance in all directions. No matter from which angle the ship collides, it can undergo elastic deformation in a relatively consistent manner and absorb the collision energy. By connecting the multiple buffer cartridges 204 and connecting spring plates 205 inside the air chamber 203 into an integral whole, the superimposed design can increase the number and complexity of buffering levels during a collision. Through the reinforcing long plate 208 and the protective spring 209 fixedly connected by the buffer inner ring 206, when it is compressed by a collision, it can provide an additional elastic restoring force for the rubber fender, helping to push the ship away from the hull of the tugboat after a ship collision, reducing the contact time and friction between the ship and the hull, and reducing the possibility of damage to the hull. Additionally, by tightly wrapping a spring protection sleeve 210 made of fiber-reinforced composite material around the outside of the protective spring 209, the protective spring 209 can be prevented from breaking and deforming under the erosion of seawater. The fiber-reinforced composite material has excellent corrosion resistance, can effectively isolate the spring from corrosive media such as seawater and air in the outside world, prevent the spring from rusting and corroding, and extend the service life of the spring, thus solving the problem of poor protection effect caused by the single structure of the existing rubber fender.

[0024] Embodiment Two: Figures 1-9As shown, the protection component 1 includes a bent fender 102, which absorbs energy and buffers when the ship collides with the ocean tugboat. It has an elastic thrust between the ship and the ocean tugboat. A plurality of hexagonal grooves 103 are provided on the top of the bent fender 102. The protection component 1 also includes a plurality of support plates 101, each of which is fixedly installed between the outer surfaces of one side of two adjacent bent fenders 102, and the outer surfaces of the other sides away from the two bent fenders 102 are fixedly connected with mounting plates 104. The support plates 101 and the mounting plates 104 are both used to realize the connection of the rubber fender as a whole. Two first through holes 105 are provided at one end of each support plate 101, and a first mounting hole 106 is provided at one end of each mounting plate 104. The plurality of first through holes 105 and the two A first fastening chain 3 is movably connected between the first mounting holes 106, the first fastening chain 3 is penetrated in a wave form, and both ends of the first fastening chain 3 are fixedly connected with a first mounting ring 4, the other end of each support plate 101 is provided with two second through holes 108, and the other end of each mounting plate 104 is provided with a second mounting hole 107, a second fastening chain 5 is movably connected between the multiple second through holes 108 and the two second mounting holes 107, and both ends of the second fastening chain 5 are fixedly connected with a second mounting ring 6, the two first mounting rings 4 and the two second mounting rings 6 are used to be fixed to the side plate of the ocean tugboat, each cylindrical fender 201 is fixedly connected between the outer surfaces of two adjacent bent fenders 102, and the multiple cylindrical fenders 201 and the multiple bent fenders 102 form a whole.

[0025] In this embodiment, when in use, the first fastening chain 3 is first used to connect the first through-holes 105 and the first mounting holes 106 on the same group of rubber fenders in series in the form of waves, and then the second through-holes 108 and the second mounting holes 107 on the same group of rubber fenders are connected in series in the same manner and in the opposite direction with the second fastening chain 5. The two first mounting rings 4 and the two second mounting rings 6 are fixed to the side plate of the tugboat by using the connecting fixture. During installation, the first fastening chain 3 and the second fastening chain 5 are in a straightened state. When the full-turn ocean tugboat collides with a ship or a shore, the cylindrical fender 201 will It is first squeezed to achieve the first energy absorption, and then the squeezed energy is transmitted to the multiple bent fenders 102 to achieve the second energy absorption. The cylindrical fender 201 and the bent fender 102 play a buffering and protective role during rebound. In the event of a lateral collision, the rubber fender will be squeezed laterally as a whole, and will rebound to its original position after being released, thereby avoiding damage to the hull caused by the displacement of the protection point during the collision. The hexagonal groove 103 opened inside the bent fender 102 can produce more deformation and displacement when it is hit, and absorb and dissipate the collision energy by compression, twisting, etc. of the groove, thereby protecting the hull structure and equipment.

[0026] Embodiment three: Figures 1-9As shown in the figure, the support plate 101, the bent fender 102, the mounting plate 104, the cylindrical fender 201, the anti-slip strip 202, the buffer cartridge 204, the connecting spring plate 205 and the buffer inner ring 206 are made of the same material. Pyrolytic carbon black particles are added to the rubber material to improve the aging resistance and wear resistance of the rubber. The rubber variety is natural rubber, and a plasticizer is added to the rubber material to reduce the interaction force between rubber molecular chains and increase the flexibility and mobility of molecular chains.

[0027] In this embodiment, when in use, the number of cylindrical fenders 201 in the same group is one less than that of the bent fenders 102. Multiple groups of rubber fenders are fixedly installed on the side plate of the fully rotating ocean tugboat in a fully enclosed manner, so as to be able to resist collisions and squeezes generated in any direction. The rubber materials used for the support plate 101, the bent fender 102, the mounting plate 104, the cylindrical fender 201, the anti-slip strip 202, the buffer cartridge 204, the connecting spring plate 205 and the buffer inner ring 206 are the same, but their structural shapes and functions are different. Pyrolytic carbon black particles are added to the conventional rubber material. The pyrolytic carbon black particles have a high specific surface area and good reinforcement performance, and can interact with rubber molecular chains to improve the mechanical properties of rubber such as tensile strength, tear strength and wear resistance. This makes the rubber fender less likely to be damaged when subjected to collisions and friction, and extends its service life. Carbon black has a certain ultraviolet absorption ability and antioxidant effect, which can improve the aging resistance of rubber and slow down the performance decline of rubber caused by factors such as light and oxidation during long-term use, and keep the performance of the rubber fender stable. In addition, the temperature of the ocean is low, and the seawater temperature is even lower in the cold season. A plasticizer is added to the rubber material of the rubber fender, which can reduce the interaction force between rubber molecular chains, increase the flexibility and mobility of molecular chains, thereby reducing the glass transition temperature of the rubber and improving its low-temperature performance, so that the rubber fender of the fully rotating ocean tugboat can also maintain good elasticity at low temperature and play a protective role for the ocean tugboat and the ship.

[0028] The method of use and working principle of the device: when in use, first use the first fastening chain 3 to connect the first through-holes 105 and the first mounting holes 106 on the same group of rubber fenders in series in the form of waves, and then connect the second through-holes 108 and the second mounting holes 107 on the same group of rubber fenders in series in the same way and in the opposite direction with the second fastening chain 5, and fix the two first mounting rings 4 and the two second mounting rings 6 on the side plate of the tugboat by using connecting fixings. When installing, the first fastening chain 3 and the second fastening chain 5 are in a straight state. When the full-turn ocean tugboat collides with the ship or the shore, the cylindrical fender 201 will be squeezed first, and the first energy absorption is realized at this time. Then, the squeezing energy is transmitted to the multiple bent fenders 102, which is effective. The second energy absorption occurs. The cylindrical fender 201 and the bent fender 102 play a buffering and protective role when rebounding. In the case of a lateral collision, the rubber fender will be squeezed laterally as a whole, and will rebound to its original position after being released. The hexagonal groove 103 opened inside the bent fender 102 can produce more deformation and displacement when it is hit, and absorb and dissipate the collision energy by compression, twisting, etc. of the groove. When in use, multiple bent fenders 102 are connected by the support plate 101 to form a W-shaped whole. The W-shaped structure enables the rubber pad to have multiple buffering stages. When hit, the W-shaped side wings first contact and deform elastically to absorb part of the energy, and then the middle part is further compressed, which can effectively absorb and disperse the energy generated by the ship collision in stages. Energy is absorbed by the tugboat, and the impact force on the hull is reduced. A cylindrical fender 201 is fixed between the two bent fenders 102. The cylindrical structure of the cylindrical fender 201 has a relatively uniform buffering performance in all directions. No matter from which angle the ship collides, it can elastically deform in a relatively consistent manner to absorb the collision energy. By connecting multiple buffer cylinders 204 and connecting springs 205 inside the air cavity 203 into a whole, when a collision occurs, the superimposed design can increase the level and complexity of buffering. The reinforced long plate 208 and the protective spring 209 fixedly connected by the buffer inner ring 206 can provide additional elastic restoring force for the rubber fender when it is compressed by the collision, which helps to push the ship away from the hull of the tugboat after the ship collides. In addition, A spring protective cover 210 made of fiber-reinforced composite material is tightly wrapped around the outside of the protective spring 209. The fiber-reinforced composite material has excellent corrosion resistance and can effectively isolate the spring from corrosive media such as seawater and air in the outside to prevent the spring from rusting and corrosion. When in use, the number of cylindrical fenders 201 in the same group is one less than the number of bent fenders 102. Multiple groups of rubber fenders are fixedly mounted on the side panels of the full-revolving ocean tugboat in a fully enclosed manner, so as to resist collision and extrusion in any direction. The rubber materials used for the support plate 101, the bent fender 102, the mounting plate 104, the cylindrical fender 201, the anti-slip strip 202, the buffer cylinder 204, the connecting spring 205 and the buffer inner ring 206 are the same.However, their structural shapes and functions are different. Pyrolytic carbon black particles are added to conventional rubber materials. The pyrolytic carbon black particles have a high specific surface area and good reinforcing properties, and can interact with rubber molecular chains to improve the mechanical properties of rubber such as tensile strength, tear strength and abrasion resistance. This makes the rubber fender less likely to be damaged when subjected to collision and friction, and extends its service life. Carbon black has a certain ultraviolet absorption ability and antioxidant effect, which can improve the aging resistance of rubber. In addition, the temperature of the ocean is low, and the seawater temperature is even lower in cold seasons. Plasticizers are added to the rubber material of the rubber fender, which can reduce the interaction force between rubber molecular chains, increase the flexibility and mobility of molecular chains, thereby reducing the glass transition temperature of rubber and improving its low-temperature performance, so that the rubber fender of the full-rotation ocean tugboat can also maintain good elasticity at low temperatures.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
