Description

Technical Field

[0001] The utility model relates to the technical field of rubber fenders, in particular to a high-strength rubber fender capable of evenly bearing stress. Background Art

[0002] Traditional rubber fenders reduce impact and protect the hull and dock when the ship is docked. However, due to structural and material limitations, ordinary solid or floating rubber fenders can only transmit the extrusion force to a small local area of ​​the fender when subjected to a large impact, resulting in uneven force on the fender. As a result, the impacted area of ​​the fender is easily damaged, shortening the service life of the fender.

[0003] In order to address the above problems, the existing Chinese patent with announcement number CN216006843U proposes a high-strength rubber fender that can evenly bear force. The device drives an extrusion rod and a buffer spring to squeeze through a fixed block. The buffer spring pair squeezes a hollow tube and disperses part of the impact force to the two sides of the fixed block, thereby increasing the force-bearing area of ​​the rubber fender. At the same time, the fixed block drives the extrusion rod to squeeze the buffer spring in the sleeve to further reduce shock and buffer. The buffer spring pair squeezes the extrusion rod to squeeze the spring, thereby transferring the impact force at the impact point to various positions of the rubber fender, making the force more even.

[0004] However, although the above-mentioned high-strength rubber fender capable of evenly applying force can push the movement of multiple sets of springs through a fixed block, and transfer the impact force at the impacted position to various positions of the rubber fender through multiple extrusion rods, thereby making the force more evenly applied, when the high-strength rubber fender capable of evenly applying force is subjected to an impact force, since the rubber fender itself has a limited buffering effect, most of the impact force applied to the rubber fender is absorbed and buffered by the multiple sets of springs. After long-term use, the internal springs are very likely to be damaged. Therefore, the present invention provides a high-strength rubber fender capable of evenly applying force to meet the demand.

[0028] like Figures 1 to 4As shown, an embodiment of the present invention provides a high-strength rubber fender capable of uniformly bearing stress, comprising a fender body 2 and a mounting plate 14. The fender body 2 comprises an inner layer 22 and an outer layer 21. Two sets of isolation layers 17 are provided between the inner layer 22 and the outer layer 21. A non-Newtonian fluid 18 is provided between the two sets of isolation layers 17. A skeleton layer 16 is provided between the outer layer 21 and the isolation layer 17. The skeleton layer 16 comprises a plurality of honeycomb-shaped skeletons.

[0029] Specifically, when subjected to an impact, the skeleton layer 16 can provide overall support and increase the structural strength of the fender body 2. At the same time, the non-Newtonian fluid 18 quickly hardens, generating a uniform reaction force and effectively absorbing the impact force. The overall multi-layer composite structure design ensures that the pressure can be evenly distributed when different parts are impacted, avoiding the problems of local overload and damage to the springs 94, significantly improving the impact resistance and wear resistance of the fender, and solving the problem that when existing rubber fenders are subjected to impact force, the impact force is mostly absorbed and buffered by the multiple groups of springs 94 due to the limited buffering effect of the rubber fender itself. After long-term use, the internal springs 94 are very likely to be damaged.

[0030] It should be noted that the material that can be installed inside the rubber fender and isolate the non-Newtonian fluid 18 should be a synthetic material with good oil resistance and chemical resistance, such as oil-resistant nitrile rubber, chloroprene rubber, PVC, etc.

[0031] like Figure 4 As shown, in this embodiment, the skeleton layer 16 is made of high-density polyethylene, and the outer layer 21 is covered with an anti-corrosion coating 15. The anti-corrosion coating 15 is an epoxy resin coating. Specifically, the anti-corrosion coating 15 can also be made of hot-dip galvanized or other materials. The anti-corrosion layer can effectively improve the anti-corrosion performance of the rubber fender and extend its service life.

[0032] like Figure 1 、 Figure 2 and Figure 3As shown, in this embodiment, two fixed plates 1 are relatively fixedly connected at both ends of the fender body 2, a fixed column 3 is fixed between the two fixed plates 1, a cavity 7 is defined in the fixed column 3, and a movable opening 5 communicating with the cavity 7 is provided on the top of the fixed column 3. A movable column 4 is movably provided in the cavity 7, and a first elastic telescopic rod 8 is hinged on the top of the movable column 4. The end of the first elastic telescopic rod 8 away from the movable column 4 is hinged to a first support plate 10, and the end of the first support plate 10 away from the first elastic telescopic rod 8 is fixedly connected to the inner layer 22, and support rods 11 are hinged between the first support plate 10 and both sides of the first elastic telescopic rod 8. A plurality of third support plates 13 are provided along the circumference direction of the movable column 4, and the third support plate 13 is arranged relative to the first elastic telescopic rod 8 shown, and the bottom of the third support plate 13 is hinged to a second Elastic telescopic rod 9, one end of the second elastic telescopic rod 9 away from the third support plate 13 extends to the outside of the fixed column 3 and is hinged with the second support plate 12, the second support plate 12 is fixedly connected to the inner layer 22, and the fixed column 3 is penetrated by a through hole 6 for the second elastic telescopic rod 9 to move. The first elastic telescopic rod 8 and the second elastic telescopic rod 9 have the same structure. The second elastic telescopic rod 9 includes a fixed rod 93, a movable plate 92 is movably provided inside the fixed rod 93, and a movable groove 95 is provided in the fixed rod 93 for the movable plate 92 to move. A spring 94 is provided at the bottom of the movable plate 92, and the spring 94 is located in the movable groove 95. The fixed rod 93 is hinged to the movable rod 91 of the movable column 4, which is fixedly connected to the movable plate 92, and the movable rod 91 is movably connected to the fixed rod 93, and the movable rod 91 is hinged to the first support plate 10.

[0033] Specifically, when the fender body 2 is subjected to pressure, the inner layer 22 will push the first support plate 10 to move, so that the first support plate 10 releases force under the action of the first elastic telescopic rod 8, and at the same time drives the first elastic telescopic rod 8 to move downward and pushes the movable column 4 downward. The movable column 4 contacts the third support plate 13, so that the third support plate 13 drives the second elastic telescopic rod 9 to move, and the second elastic telescopic rod 9 releases force on the movable column 4. At the same time, the impact force is dispersed to various positions of the fender body 2 through the second support plate 12, so that the fender body 2 can be evenly stressed. It should be noted that the length of the first support plate 10 is greater than the length of the second support plate 12, and the first support plate 10 and the second support plate 12 are both arranged along the length direction of the fender body 2. The installation of the first elastic telescopic rod 8 and the second elastic telescopic rod 9 can be installed according to actual conditions. For details, please refer to Figure 2 At the same time, the fixed column 3 and the movable column 4 are both cylindrical structures, and the diameter of the movable opening 5 is smaller than the diameter of the movable column 4 and larger than the diameter of the fixed rod 93.

[0034] Working principle:

[0035] First, the fender body 2 on one side of the first support plate 10 is set to the impact position. When impacted, the skeleton layer 16 can provide overall support and increase the structural strength of the fender body 2. At the same time, the non-Newtonian fluid 18 quickly hardens to generate a uniform reaction force, effectively absorbing the impact force. At the same time, the inner layer 22 will push the first support plate 10 to move, so that the first support plate 10 releases force under the action of the first elastic telescopic rod 8, and at the same time drives the first elastic telescopic rod 8 to move downward and pushes the movable column 4 downward. The movable column 4 contacts the third support plate 13, so that the third support plate 13 drives the second elastic telescopic rod 9 to move, and the second elastic telescopic rod 9 contacts the movable column 4 is used to release the force, and at the same time, the impact force is dispersed to various positions of the fender body 2 through the second support plate 12, so that the fender body 2 can be evenly stressed. The overall multi-layer composite structure design ensures that the pressure can be evenly dispersed when different parts are impacted, avoiding the problems of local overload and damage to the spring 94, significantly improving the impact resistance and wear resistance of the fender, and solving the problem that when the existing rubber fender is subjected to impact force, due to the limited buffering effect of the rubber fender itself, most of the impact force on the rubber fender is absorbed and buffered by the multiple groups of springs 94, and the internal springs 94 are easily damaged after long-term use.
