Description

Technical Field

[0001] This utility model relates to the field of fender technology, specifically to a compression overload limiting structure for a rubber fender mooring device. Background Technology

[0002] Rubber fenders are protective devices installed on the shore to support ships. They are made by placing a rubber plate at the top of the fender that abuts against the ship, thus preventing the ship from directly contacting the shore and causing collisions. However, as ships become larger, the pressure on the rubber fenders increases. Excessive impact can cause the rubber plate to compress the internal springs beyond its maximum value, resulting in damage. Overload limiting structures are needed to protect against damage caused by overload.

[0003] Existing compression overload devices generally buffer the compression of the fender by adding a buffer mechanism. This can only increase the maximum overload value of the entire fender, but cannot prevent the fender from being compressed too much after overload, which will lead to fender damage and reduce the service life of the fender.

[0004] According to the utility model disclosed in CN222024989U, a conical rubber fender overload protection structure is provided, comprising: a base; a first bracket fixedly installed on the end face of the base; and a second bracket slidably engaged with the first bracket. The conical rubber fender overload protection structure provided by this utility model, by providing a second bracket slidably engaged on the first bracket, allows the second bracket to move inwards towards the first bracket when subjected to external force, thereby providing cushioning for the second bracket.

[0005] The conical rubber fender overload protection structure described above can only increase the maximum overload value of the fender, but cannot achieve the limiting effect under overload. That is, it has the problem mentioned above that it cannot compress and limit the internal spring of the fender, which leads to damage. Therefore, we need to propose a compression overload limiting structure for the rubber fender mooring device. Utility Model Content

[0006] The purpose of this utility model is to provide a compression overload limiting structure for a rubber fender berthing device. Through the installation of mounting components, the fender device is installed and fixed. Through the buffer component, the moving plate receives the pressure from the ship during berthing and moves, thereby compressing the first spring. The first spring absorbs the compression and transmits the pressure through the support plate, support rod, and mounting base to the dock and riverbank, thus achieving a buffering effect for the ship during berthing. When the ship's pressure is too great, the limiting component causes the moving plate to compress the first spring and simultaneously move four sets of sliding rods. When the first spring is compressed to its limit, one end of each of the four sets of sliding rods is restricted by one end of a limit rod, stopping the four sets of sliding rods from moving further. This limits further compression of the first spring, preventing damage due to excessive compression, and thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a compression overload limiting structure for a rubber fender berthing device, comprising an installation assembly, one end of which is fitted with a buffer assembly for berthing protection of the hull, and a limiting assembly is installed between the installation assembly and the buffer assembly; the installation assembly includes a mounting base, one side of which is fixedly connected to a support plate via a support rod; the buffer assembly includes a first spring fixedly welded to the outside of the support plate, one end of which is fitted with a movable plate; the limiting assembly includes four sets of sliding rods movably mounted through one side of the support plate, one end of each of the four sets of sliding rods being fixedly connected to one side of the movable plate, and the limiting assembly further includes four sets of limiting rods fixedly mounted to the mounting base.

[0008] Preferably, the outer arc surface of the slide rod located between the support plate and the moving plate is fitted with a second spring, and the two ends of the four sets of second springs are respectively welded to the opposite sides of the support plate and the moving plate.

[0009] Preferably, a first limiting plate is installed at one end of each of the four sets of sliding rods located between the mounting base and the support plate, and a second limiting plate is installed at one end of each of the four sets of limiting rods.

[0010] Preferably, a rubber guard plate is attached to the outer side of the movable plate, and both ends of the movable plate and the rubber guard plate are rounded.

[0011] Preferably, the outer side of the rubber protective plate is provided with several sets of concave grooves, which are evenly distributed vertically.

[0012] Preferably, each of the four corners of the mounting base has a set of mounting holes, and the mounting base is fixed by a set of fixing rods inserted into each of the four sets of mounting holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes a limiting component and the connection between the sliding rod, limiting rod, mounting base, support plate, and moving plate. When the moving plate is subjected to the squeezing force of the ship, its movement compresses the first spring. As the first spring compresses, it drives four sets of sliding rods to slide on the support plate. When the first spring is compressed to its limit, one end of each of the four sets of sliding rods is restricted by the four sets of limiting rods installed on it, causing the four sets of sliding rods to stop sliding further. This locks the first spring from further compression, preventing damage due to excessive compression and improving the service life of the fender device.

The objectives and other advantages of this invention can be realized and obtained through the structures pointed out in the description and the accompanying drawings. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-4This utility model provides a compression overload limiting structure for a rubber fender berthing device, including an installation component 1. One end of the installation component 1 is equipped with a buffer component 2 for berthing protection of the hull. A limiting component 3 is installed between the installation component 1 and the buffer component 2. The installation component 1 includes a mounting base 11, and a support plate 13 is fixedly connected to one side of the mounting base 11 via a support rod 12. The buffer component 2 includes a first spring 21 fixedly welded to the outside of the support plate 13, and a movable plate 22 is installed at one end of the first spring 21. The limiting component 3 includes four sets of sliding rods 31 that are movably installed through one side of the support plate 13. One end of each of the four sets of sliding rods 31 is fixedly connected to one side of the movable plate 22. The limiting component 3 also includes four sets of limiting rods 34 fixedly installed on the mounting base 11.

[0023] In use, the installation component 1 enables the installation and fixation of the fender device. The buffer component 2 allows the movable plate 22 to move in response to the pressure exerted by the ship during berthing, thereby compressing the first spring 21. The first spring 21 absorbs and transmits the pressure through the support plate 13, support rod 12, and mounting base 11 to the dock and riverbank, thus achieving a buffering effect for the ship during berthing. When the pressure exerted by the ship is too great, the limiting component 3 causes the movable plate 22 to move, compressing the first spring 21 and simultaneously moving the four sets of sliding rods 31. The sliding rods 31 control the direction of movement of the movable plate 22, improving the stability of its movement. When the first spring 21 is compressed to its limit, one end of each of the four sets of sliding rods 31 is restricted by one end of the four sets of limiting rods 34, stopping the four sets of sliding rods 31 from moving further and thus limiting the further compression of the first spring 21, preventing damage due to excessive compression.

[0024] The slide bar 31 is located between the support plate 13 and the movable plate 22. The outer arc surface is fitted with a second spring 33. The two ends of the four sets of second springs 33 are respectively welded to the opposite sides of the support plate 13 and the movable plate 22. Through the connection between the support plate 13, the movable plate 22, the slide bar 31 and the second springs 33, when the movable plate 22 moves the slide bar 31, the movable plate 22 squeezes the second springs 33, thereby further buffering the ship's docking.

[0025] Each of the four sets of sliding rods 31 has a first limiting plate 32 installed at one end between the mounting base 11 and the support plate 13, and each of the four sets of limiting rods 34 has a second limiting plate 35 installed at one end. When the first spring 21 is compressed to its limit value, the first limiting plate 32 and the second limiting plate 35 come into contact with each other, thereby achieving the effect of locking the movement of the sliding rod 31 and preventing the first spring 21 from being damaged due to continued compression. In addition, the first limiting plate 32 limits the sliding rod 31 and prevents the sliding rod 31 from falling off the support plate 13.

[0026] A rubber guard plate 23 is fitted to the outside of the movable plate 22. The rubber guard plate 23 can prevent the hull from making rigid contact with the movable plate 22, thus preventing damage and scratches to the hull. Both ends of the movable plate 22 and the rubber guard plate 23 are rounded. The rounded shape can buffer and protect the hull, preventing damage caused by direct contact between the hull and sharp ends.

[0027] The outer side of the rubber guard plate 23 is provided with several sets of concave grooves 24. The sets of concave grooves 24 are evenly distributed vertically. By setting the concave grooves 24, the deformation of the rubber guard plate 23 when it is squeezed can be increased, thereby improving the buffering effect. At the same time, the concave grooves 24 can increase the friction force and prevent the hull from sliding with the rubber guard plate 23 when the hull is moored.

[0028] The mounting base 11 has a set of mounting holes 14 through each of its four corners. The mounting base 11 is fixed by a set of fixing rods 15 inserted into each of the four sets of mounting holes 14. Through the connection between the mounting base 11, the mounting holes 14, and the fixing rods 15, the mounting base 11 can be fixedly installed at a designated position on the shore by the fixing rods 15, thereby achieving the effect of quick installation and fixation of the fender device.

[0029] In practical use: The fender device is fixedly installed at the designated position on the dock via the mounting base 11. With the setting of the buffer component 2, when the ship docks, it compresses the rubber guard plate 23 and the movable plate 22. The movable plate 22 and the rubber guard plate 23 move to one side, thereby compressing the first spring 21. The first spring 21 absorbs the compression and transmits the compressive force to the dock bank through the support plate 13, the support rod 12, and the mounting base 11. When the movable plate 22 and the rubber guard plate 23 move, they compress the second spring 33, thereby achieving the effect of buffering the ship's docking. When the movable plate 22 and the rubber guard plate 23 move, they drive the four sets of limiting rods 34 to move. When the compression of the first spring 21 reaches its maximum value, one end of each of the four sets of sliding rods 31 is restricted by one end of the four sets of limiting rods 34, causing the four sets of sliding rods 31 to stop moving. This limits the continued compression of the first spring 21 and prevents the first spring 21 from being damaged due to excessive compression. The second spring 33 has a larger deformation limit than the first spring 21 and does not need to be considered.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
