Abstract
Description
Technical Field
[0001] This utility model relates to the field of marine fender technology, and in particular to a pressure-resistant and wear-resistant marine fender. Background Technology
[0002] Marine fenders are elastic buffer devices that are directly installed or suspended on the sides of a ship to absorb the impact energy generated when the ship is berthed, moored, or comes into contact with other ships or docks, protecting the hull, docks, and other facilities from collision damage.
[0003] Common fenders are elastic buffer devices used at the edges of docks or ships. They are made of wood or rubber and usually slide and rub against the hull or dock to prevent direct collisions between the hull and the dock, thus avoiding damage to the dock or hull. However, fenders can deform severely during sliding friction and compression, so common wooden fenders and rubber fenders have a short service life and cannot be used for a long time. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of existing technologies and to propose a pressure-resistant and wear-resistant marine fender. To achieve the above objective, this utility model adopts the following technical solution:

[0006] The present invention is further configured such that the unloading structure includes: an unloading airbag and several limiting plates; the unloading airbag is installed on the front wall of the mounting base plate by ropes, the several limiting plates are installed inside the unloading airbag, and the several limiting plates are located outside the buffer structure.
[0007] The present invention is further configured such that the anti-friction structure includes: an anti-friction fixing plate and a plurality of anti-friction rubber rollers; the anti-friction fixing plate is installed on the front wall of the pressure relief airbag, and the plurality of anti-friction rubber rollers are respectively installed on the front wall of the anti-friction fixing plate.
[0008] The present invention is further configured such that four countersunk through holes are provided on the front side of the mounting base plate.

[0010] The present invention is further configured such that the anti-friction fixing plate has two clearance grooves, and the two clearance grooves of the anti-friction fixing plate provide clearance for the buffer structure.
[0011] The beneficial effects of this utility model are as follows: By setting a two-stage buffer structure, this utility model can buffer the hull in two stages, which can effectively ensure that the hull will not impact the dock. Furthermore, by setting several rubber wheels, rolling friction can occur between the hull and the fender, greatly reducing friction and protecting the fender. This can also improve the service life of the fender to a certain extent and reduce the cost of using the fender. Attached Figure Description

[0022] As a preferred embodiment, the stress-relieving structure further includes: a stress-relieving airbag 7 and several limiting plates 8; the stress-relieving airbag 7 is installed on the front wall of the mounting base plate 1 by ropes, and the several limiting plates 8 are installed inside the stress-relieving airbag 7 and are located outside the buffer structure.
[0023] As a preferred embodiment, the anti-friction structure further includes: an anti-friction fixing plate 9 and several anti-friction rubber rollers 10; the anti-friction fixing plate 9 is installed on the front wall of the pressure relief airbag 7, and several anti-friction rubber rollers 10 are respectively installed on the front wall of the anti-friction fixing plate 9; anti-scratching arc plates 12 are provided on both sides of the anti-friction fixing plate 9; the anti-friction fixing plate 9 has two clearance grooves, and the two clearance grooves of the anti-friction fixing plate 9 provide clearance for the buffer structure.
[0024] Working principle: Before using this utility model, the operator needs to install it. The operator makes several holes on the wharf wall to install the buffer limit sleeve 2. Then, the operator fixes the mounting base plate 1 directly to the wharf wall by passing screws through the countersunk through hole 11. Then, the operator installs the unloading airbag 7 on the front wall of the mounting base plate 1 by using ropes. Finally, the operator installs the anti-friction fixing plate 9 on the front wall of the unloading airbag 7 by using ropes. At this time, the installation of this utility model is completed.
[0025] When the hull approaches the present invention, the buffer rubber wheel 6 first contacts the hull, at which point the buffer rubber wheel 6 is compressed. The buffer wheel seat 4 drives the buffer slide rod 3 to slide into the buffer limiting sleeve 2, and the buffer spring 5 is continuously compressed. According to Hooke's law, within the elastic limit, the pressure on the spring is proportional to the deformation. As the compression of the buffer spring 5 increases, the buffer force provided to the buffer rubber wheel 6 is greater, allowing the hull to approach stably. When the buffer rubber wheel 6 moves to be flush with the dry anti-friction rubber roller 10, the hull and several buffers... The impact rubber wheel 6 and several anti-friction rubber rollers 10 come into contact simultaneously, and as the hull continues to approach, the unloading airbag 7 is also compressed. The unloading airbag 7 can provide additional cushioning force, allowing the hull to approach more stably. The unloading airbag 7 is equipped with a limiting plate 8, which can prevent the unloading airbag 7 from expanding inward and avoid interference between the unloading airbag 7 and the cushioning rubber wheel 6. Due to the presence of the cushioning rubber wheel 6 and the anti-friction rubber rollers 10, the friction between the hull and the dock is rolling friction, which is relatively small and can effectively protect the hull.
[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
