Description

Technical Field

[0001] This utility model relates to the field of wharf fenders, and in particular to a wharf fender with good buffering effect. Background Technology

[0002] A pier fender is an elastic buffer device installed on a pier, mainly used to reduce the impact force on the pier during the berthing or mooring of ships, and to prevent or eliminate damage to ships and piers.

[0003] Fenders typically absorb energy using elastic materials such as rubber. A search reveals Chinese Patent Publication No. CN214363307U, which discloses an adjustable-angle energy-absorbing dock fender. This fender includes an airbag with a steel cable wound around its outer ring. The steel cable is fixedly connected to the middle of a wear-resistant ring on the outer wall of the airbag. The bottom end of the steel cable is fixedly connected to the middle of a fixing block. The top of the fixing block is fixedly connected to the top of an adjusting shell. The top of the adjusting shell is fixedly connected to the bottom of the airbag. The bottom of the airbag, near the fixing block, is fixedly connected to the bottom of a first mounting block. This adjustable-angle energy-absorbing dock fender utilizes an adjusting propeller. During adjustment, when the motors on both sides of the adjusting shell rotate in the same direction, they drive a rotating rod, causing the first and second bevel gears to rotate, which in turn rotates the shaft. The adjusting propeller then moves the airbag back and forth for adjustment. When the motors on both sides of the adjusting shell rotate in opposite directions, the adjusting propellers on both sides of the adjusting shell rotate in opposite directions, causing the airbag to rotate for further adjustment.

[0004] The existing technical solutions mentioned above have the following drawbacks: In the use of fender airbags in the above technical solutions, energy is generally absorbed by the rubber elastic material of the fender airbag itself, which has limited energy absorption capacity. The friction between the fender and the hull is large, which can easily damage the hull and reduce the service life of the fender. Therefore, a dock fender with good buffering effect is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a dock fender with good buffering effect, which aims to improve the problem that the existing technology only relies on the rubber elastic material of the fender airbag itself to absorb energy, which has limited energy absorption capacity and is prone to damage to the hull.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A fender with good cushioning effect includes a fender airbag. An inner protective sleeve is longitudinally fixedly connected inside the fender airbag. A rubber support sleeve is fixedly connected to the surface of the inner protective sleeve. A support rod is longitudinally fixedly connected inside the inner protective sleeve. A movable rod one is movably connected to the surface of the support rod. A movable rod two is movably connected to the inner wall of the inner protective sleeve via a support member. A buffer spring is sleeved on the surface of the movable rod one. The outer side of the buffer spring is sleeved on the outer side of the movable rod two. A reinforcing spring is transversely fixedly connected to the inner side of the buffer spring. A support assembly is provided on the inner side of the buffer spring. Pulling assemblies are provided on the inner sides of both the buffer spring and the reinforcing spring. A reinforcing assembly is fixedly connected to the surface of the rubber support sleeve. A buffer assembly is fixedly connected to the inner wall of the fender airbag. A wear-resistant assembly is fixedly connected to the surface of the fender airbag.

[0008] As a further description of the above technical solution:

[0009] The support assembly includes a support plate located inside the buffer spring.

[0010] As a further description of the above technical solution:

[0011] The pulling assembly includes a pulling spring, which is fixedly connected to the outside of the support plate, and the outside of the pulling spring is fixedly connected to the inside of the buffer spring.

[0012] As a further description of the above technical solution:

[0013] The reinforcing component includes a polyurethane reinforcing sleeve, which is fixedly connected to the surface of the rubber support sleeve.

[0014] As a further description of the above technical solution:

[0015] The buffer spring includes a protective spring, which is fixedly connected to the inner wall of the fender airbag, and the inner side of the protective spring is fixedly connected to the surface of the rubber support sleeve.

[0016] As a further description of the above technical solution:

[0017] The protective spring is vertically slidably connected to a limiting rod inside. The outer side of the limiting rod extends into the interior of the fender airbag, and the inner side of the limiting rod extends into the interior of the polyurethane reinforcing sleeve.

[0018] As a further description of the above technical solution:

[0019] Both the buffer spring and the reinforcing spring have protective rods slidably connected inside, and the inner side of the protective rods is fixedly connected to the surface of the support plate.

[0020] As a further description of the above technical solution:

[0021] The wear-resistant component includes a polyurethane wear-resistant sleeve, which is fixedly connected to the surface of the fender airbag.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the rubber support sleeve, support rod, movable rod one and movable rod two work together to drive the buffer spring and reinforcing spring to deform, thereby achieving strong buffering when the ship is squeezed by the fender airbag while docking.

[0024] 2. In this utility model, the wear resistance of the fender airbag surface can be effectively increased by the cooperation of the polyurethane wear-resistant sleeve, the protective spring, and the polyurethane reinforcing sleeve structure, so as to solve the problem of reduced service life after the fender airbag surface is easily worn.

[0031] 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.

[0032] Reference Figure 1-3 This utility model provides an embodiment of a dock fender with good cushioning effect, including a fender airbag 1. An inner protective sleeve 2 is longitudinally fixedly connected inside the fender airbag 1, enhancing the cushioning effect of the airbag 1. A rubber support sleeve 3 is fixedly connected to the surface of the inner protective sleeve 2, enhancing its impact resistance. A support rod 4 is longitudinally fixedly connected inside the inner protective sleeve 2, supporting a movable rod 5 and a buffer spring 7. A movable rod 5 is movably connected to the surface of the support rod 4, supporting the buffer spring 7. The inner wall of the inner protective sleeve 2 is movably connected to a support member. Movable rod 2 6 can support the buffer spring 7. The surface of movable rod 1 5 is fitted with the buffer spring 7. The buffer spring 7 can provide buffer protection after the fender airbag 1 deforms. The outer side of the buffer spring 7 is fitted on the outer side of movable rod 2 6. The inner side of the buffer spring 7 is laterally fixedly connected with a reinforcing spring 8. The reinforcing spring 8 can enhance the buffering effect of the buffer spring 7. The inner side of the buffer spring 7 is provided with a support component. The inner sides of both the buffer spring 7 and the reinforcing spring 8 are provided with a pulling component. The surface of the rubber support sleeve 3 is fixedly connected with a reinforcing component. The inner wall of the fender airbag 1 is fixedly connected with a buffer component. The surface of the fender airbag 1 is fixedly connected with a wear-resistant component.

[0033] Reference Figure 2-4 The reinforcing components include a polyurethane reinforcing sleeve 11, which enhances the impact resistance of the rubber support sleeve 3 surface and effectively increases the cushioning effect of the rubber support sleeve 3 during deformation. The polyurethane reinforcing sleeve 11 is fixedly connected to the surface of the rubber support sleeve 3. The buffer spring 7 includes a protective spring 12, which reduces the impact after the fender airbag 1 is hit by the hull. The protective spring 12 is fixedly connected to the inner wall of the fender airbag 1, and the inner side of the protective spring 12 is fixedly connected to the surface of the rubber support sleeve 3.

[0034] Reference Figure 2-4The support assembly includes a support plate 9, which is located inside the buffer spring 7 and can support the pulling spring 10. The pulling assembly includes a pulling spring 10, which is fixedly connected to the outside of the support plate 9. The outside of the pulling spring 10 is fixedly connected to the inside of the buffer spring 7. The pulling spring 10 can pull the buffer spring 7 and the reinforcing spring 7 during deformation, thereby reducing the deformation time of the buffer spring 7 and the pulling spring 10 after the fender airbag 1 is compressed, thus increasing the buffering effect of the buffer spring 7 and the reinforcing spring 8. The inner vertical sliding connection of the protective spring 12 is a limiting rod 13. The outer side of the limiting rod 13 extends into the interior of the fender airbag 1, and the inner side of the limiting rod 13 extends into the interior of the polyurethane reinforcing sleeve 11. The limiting rod 13 can limit the protective spring 12, so that the protective spring 12 can be used elastically and stably. The buffer spring 7 and the reinforcing spring 8 are both slidably connected to the interior of the protective rod 14. The inner side of the protective rod 14 is fixedly connected to the surface of the support plate 9. The protective rod 14 can limit the pulling spring 10. The wear-resistant component includes a polyurethane wear-resistant sleeve 15. The polyurethane wear-resistant sleeve 15 is fixedly connected to the surface of the fender airbag 1. The polyurethane wear-resistant sleeve 15 can enhance the wear resistance of the surface of the fender airbag 1, so that the surface of the fender airbag 1 is not easily worn.

[0035] Working principle: When the fender airbag 1 is in contact with the hull while the ship is docking, the fender airbag 1, inner protective sleeve 2, and rubber support sleeve 3 deform under impact. Meanwhile, the buffer springs 7, movably connected to the surfaces of movable rods 5 and 6, deform under the pressure of the dock breastwork and the hull, absorbing and reducing the impact force. The reinforcing spring 8 is also deformed after being compressed by the buffer spring 7, further enhancing its absorption of impact force and strengthening the buffering force of the fender airbag 1. Additionally, the spring 10 is pulled after the buffer spring 7 and reinforcing spring 8 are deformed. Elastic stretching further enhances the buffering effect of buffer spring 7 and reinforced spring 8 during use, while protective spring 12 and polyurethane reinforcing sleeve 11 enhance the buffering protection effect of inner protective sleeve 2, thereby achieving strong buffering of the hull and effectively buffering the fender airbag 1 when the hull is approaching the shore. In addition, polyurethane wear-resistant sleeve 15 is fixedly connected to the surface of fender airbag 1, which can enhance the wear resistance of the surface of fender airbag 1, making the surface of fender airbag 1 less prone to wear and reducing its service life, thereby effectively improving the wear resistance of the surface of fender airbag 1 and increasing its service life.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
