Description

Technical Field

[0001] This utility model relates to the field of dock fender technology, specifically to a highly elastic, anti-slip rubber fender suitable for docks. Background Technology

[0002] Dock fenders are buffer devices installed at the edge of a quay, primarily used to mitigate the impact between a ship and the quay during berthing or mooring, preventing or reducing damage to both. Dock fenders are indispensable equipment in modern ports and docks, not only protecting the safety of the dock and ships but also improving port operational efficiency and sustainability.

[0003] When using rubber fenders, the high salt content of seawater corrodes the rubber material, causing a decline in its performance and shortening its service life. This results in a higher replacement frequency for rubber fenders, increasing maintenance costs. Furthermore, fenders are generally installed with bolts, which can loosen when facing large ships or high-intensity impacts, reducing their stability and affecting the overall protective effect.

[0004] Therefore, we proposed a highly elastic, anti-slip rubber fender suitable for docks to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a highly elastic, anti-slip rubber fender suitable for docks, in order to solve the problems mentioned in the background art, such as the performance reduction caused by seawater corrosion of rubber fenders, resulting in a shorter service life and a higher replacement frequency, and the high-intensity impact of large ships approaching causing the bolts fixing the fenders to slip, resulting in reduced stability and affecting the protective effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-elasticity anti-slip rubber fender suitable for docks, comprising a base and a fender, wherein the base is provided with a connecting component for installation with the fender, the connecting component includes an installation groove provided inside the base, the inner wall of the installation groove is provided with multiple through holes, each of the multiple through holes is provided with a bolt, the inner wall of the installation groove is provided with a slot, and a connecting plate is provided inside the slot;

[0007] The connecting plate has multiple docking grooves on one side, and magnets are provided on the inner walls of the multiple docking grooves. The connecting plate has multiple connecting rods on the other side, and ball bearings are provided at the other ends of the multiple connecting rods. The slots have multiple cavities on the inner walls, and springs and pistons are provided inside the multiple cavities. A hydraulic chamber is provided at one end of each cavity, and multiple magnetic plates are provided at one end of the fender.

[0008] Preferably, one end of the fender can slide into the mounting groove, and the array of multiple through holes is distributed on the inner wall of the mounting groove. One end of the bolt is located in the through hole and is rotatably connected to the inner wall of the through hole.

[0009] Preferably, the bolt can extend and retract within the through hole during rotation due to its surface thread. After the bolt extends into the mounting groove, it abuts against the positioning hole on the outer wall of the fender, and the bolt pushes the fender into the groove.

[0010] Preferably, the connecting plate is located in the slot and is slidably connected to the inner wall of the slot. A plurality of the docking slot arrays are distributed on one side of the connecting plate, and the distribution position of the docking slots corresponds to the magnetic plate at one end of the fender. After the fender extends into the slot, the magnetic plate on the outer wall is embedded in the docking slot and is magnetically connected to the magnet.

[0011] Preferably, the multiple connecting rod arrays are distributed on the side of the connecting plate near the inner wall of the slot, and the position of the connecting rods corresponds to the cavity of the inner wall of the slot. One end of the connecting rod is rotatably connected to the outer wall of the connecting plate through a fixed shaft, and the other end extends into the cavity and is connected to the ball bearing.

[0012] Preferably, the spring is located inside the cavity, and its two ends are connected to the piston and the ball respectively. The side of the piston away from the cavity is a hydraulic chamber, and the hydraulic chamber is filled with hydraulic oil. One end of the piston is rotatably connected to the inner wall of the hydraulic chamber through a fixed shaft.

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

[0014] 1. The fender can be slidably extended into the mounting slot from above through the mounting slot opening at the top of the base. This sliding motion connects the fender to the base, improving installation efficiency. Bolts are then rotated within the through-hole to extend the fender area into the mounting slot, pushing it into the groove. A retractable connecting plate within the groove supports the fender, enabling quick assembly and disassembly, thus improving replacement efficiency. Furthermore, a coating applied to the exterior of the fender effectively reduces seawater corrosion, extending its service life.

[0015] 2. When the ship comes into contact with the fender, the fender can push the connecting plate to retract into the slot. At the same time, the connecting rod pushes the ball to retract in the cavity, compressing the spring and pushing the piston to rotate in the hydraulic chamber to compress the oil. The hydraulic oil provides a buffering and supporting effect for the fender, improving its impact resistance and enhancing its performance.

[0016] This invention connects the fender to the base by sliding, thereby enabling quick replacement and unloading of the fender, improving loading and unloading efficiency. A protective layer is applied to the outside of the fender to reduce the impact of seawater on the fender. At the same time, the hydraulic support structure inside the base improves the impact resistance of the fender, ensuring its performance. Attached Figure Description

The connecting component includes an installation groove 2 inside the base 1 for angular positioning of the fender 9 during installation. When installing the fender 9, one side of the fender 9 is inserted into the installation groove 2, thereby allowing the fender 9 to slide and connect with the base 1. The inner wall of the installation groove 2 has multiple through holes 3 for angular positioning of bolts 301. Bolts 301 are installed inside each of the multiple through holes 3. The outer wall texture of the bolts 301 corresponds to the angle of the inner wall of the through holes 3. Therefore, the bolts 301 can extend and retract within the through holes 3 when rotated. After the fender 9 is installed, rotating the bolts 301 causes them to extend into the through holes 3 and abut against the fender 9, pushing the fender 9 into the slot 4 for angular positioning of the fender 9. The inner wall of the installation groove 2 has slots 4, and a connecting plate 5 is installed inside the slots 4.

[0024] In this embodiment: one end of the fender 9 can be slidably inserted into the base 1 through the mounting groove 2, and the fender 9 and the base 1 can be slidably installed and removed. After installation, the bolt 301 is rotated to engage with the thread on the surface of the bolt 301 to extend into the mounting groove 2 and abut against the fender 9, pushing the fender 9 into the hole groove 4, thereby positioning the installation angle of the fender 9 and the base 1. The sliding structure allows for quick installation and removal of the fender 9 and the base 1, improving operational efficiency. Furthermore, applying a protective coating to the surface of the fender 9 can reduce the corrosion of the fender 9 by seawater, increase the friction between the fender 9 and the ship, prevent slippage between the ship and the fender 9, and ensure the performance of the fender 9.

[0025] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figures 1-4Multiple mating grooves 501 are provided on one side of the connecting plate 5. The angle of the mating grooves 501 corresponds to the magnetic plate 901 on one side of the fender 9. Therefore, when the bolt 301 pushes the fender 9 into the slot 4, the fender 9 fits against the connecting plate 5. At the same time, the magnetic plate 901 on one side of the fender 9 is embedded in the mating groove 501 on one side of the connecting plate 5 and is magnetically attracted to the magnet 502 on the inner wall of the mating groove 501, thereby positioning the angle when the fender 9 fits against the connecting plate 5. Magnets 502 are provided on the inner walls of the multiple mating grooves 501. Multiple connecting rods 6 are provided on the other side of the connecting plate 5. The connecting rods 6 link the connecting plate 5 with the ball bearing 601 on the other end. The other end of each of the 6 is equipped with a ball bearing 601. When the ship comes into contact with the fender 9, it will push the fender 9 to retract and push the connecting plate 5 into the slot 4. At the same time, the connecting rod 6 will drive the ball bearing 601 to slide in the cavity 7. The inner wall of the slot 4 is provided with multiple cavities 7. Each of the multiple cavities 7 is provided with a spring 701 and a piston 702. The spring 701 and piston 702 can support the ball bearing 601. One end of the cavity 7 is provided with a hydraulic chamber 8. The hydraulic oil loaded in the hydraulic chamber 8 acts on the piston 702, which can cooperate with the spring 701 and the connecting rod 6 to support the connecting plate 5. One end of the fender 9 is provided with multiple magnetic plates 901; one end of the fender 9 can The bolt 301 slides into the mounting groove 2. Multiple through holes 3 are arrayed on the inner wall of the mounting groove 2. One end of the bolt 301 is located in the through hole 3 and is rotatably connected to the inner wall of the through hole 3. The bolt 301 can extend and retract within the through hole 3 during rotation due to its surface thread. After the bolt 301 extends into the mounting groove 2, it abuts against the positioning hole on the outer wall of the fender 9. The bolt 301 pushes the fender 9 into the slot 4. The connecting plate 5 is located in the slot 4 and is slidably connected to the inner wall of the slot 4. Multiple mating grooves 501 are arrayed on one side of the connecting plate 5, and the distribution position of the mating grooves 501 corresponds to the magnetic plate 901 at one end of the fender 9. After the fender 9 extends into the slot 4, the outer wall of the fender 9... The magnetic plate 901 of the wall is embedded in the docking groove 501 and magnetically connected to the magnet 502. Multiple connecting rods 6 are arrayed on the side of the connecting plate 5 near the inner wall of the slot 4. The position of the connecting rods 6 corresponds to the cavity 7 of the inner wall of the slot 4. One end of the connecting rod 6 is rotatably connected to the outer wall of the connecting plate 5 through a fixed shaft, and the other end extends into the cavity 7 and is connected to the ball 601. The spring 701 is located in the cavity 7, and its two ends are connected to the piston 702 and the ball 601 respectively.

One end of the piston 702 is rotatably connected to the inner wall of the hydraulic chamber 8 through a fixed shaft.

[0026] In this embodiment: when the ship docks and comes into contact with the fender 9, the fender 9 can push the connecting plate 5 to retract into the slot 4. At the same time, the connecting rod 6 at the other end of the connecting plate 5 drives the ball 601 to slide in the cavity 7 and squeeze the piston 702. This pushes the piston 702 to rotate into the hydraulic chamber 8 and squeeze the hydraulic oil. The hydraulic oil and the supporting force of the spring 701 achieve buffering when the ship touches the fender 9, improving the impact resistance of the fender 9 and ensuring the buffering effect of the fender 9 on the ship docking.

[0027] Working principle: In use, the fender 9 is first slidably inserted into the mounting groove 2, so that the fender 9 and the base 1 are slidably installed. Then, the bolt 301 is rotated to extend into the through hole 3 and abut against the fender 9, pushing the fender 9 to slide into the hole groove 4 and fit against the connecting plate 5. At the same time, the magnetic plate 901 at one end of the fender 9 is embedded into the docking groove 501 on one side of the connecting plate 5 and magnetically attracted with the magnet 502, realizing the connection and disassembly of the fender 9. When the ship docks and abuts against the fender 9, the impact force of the ship causes the fender 9 to push the connecting plate 5 into the hole groove 4. At the same time, multiple connecting rods 6 on the other side of the connecting plate 5 work together to make the ball 601 slide in the cavity 7 and squeeze the spring 701 and piston 702, and make the piston 702 rotate into the hydraulic chamber 8 to compress the hydraulic oil. The hydraulic oil, together with the spring 701, provides buffer support for the fender 9, reducing the impact of the ship on the fender 9 and improving the impact resistance of the fender 9.
