Description

Technical Field

[0001] This utility model relates to the field of rubber fender technology, and in particular to a rubber fender with good wear resistance. Background Technology

[0002] Rubber fenders are mainly used to absorb the collision energy between ships and docks or between ships when they are berthed or moored, in order to protect ships and docks from damage. They play a role in buffering and shock absorption, reducing the impact of collision forces, mitigating the impact on the hull, preventing damage to the hull, water leakage and other situations, and ensuring the normal operation of the ship.

[0003] A wear-resistant rubber fender (CN210310813U) can be referenced in existing literature. The reference describes a first rubber fender with a composite protective layer on its outer surface to protect its exterior. The wear-resistant layer and the buffer layer provide external shock absorption and wear resistance, thereby effectively increasing its wear resistance and service life, achieving a strong wear resistance effect. The bottom of the first rubber fender has a lower protective layer, in which a rubber shock-absorbing layer reduces the vibration received by the fixed base layer, which can prevent the rubber fender from being subjected to greater wear at the installation point.

[0004] Because rubber fenders are frequently subjected to impacts from ships during daily use, their surfaces are constantly worn down. As mentioned in the literature above, adding a protective layer to the surface of the rubber fender can improve its wear resistance. While this design can improve the wear resistance of the material, when encountering lateral stress, the contact surface between the ship and the rubber fender will generate significant friction. Due to the high coefficient of friction of rubber, the contact surface of the rubber fender is prone to wear and scratches when subjected to significant lateral stress. Therefore, the wear resistance of rubber fenders can be further improved. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a rubber fender with excellent wear resistance. This invention utilizes multiple rolling wheels installed at the front end of the impact section. These rolling wheels are capable of horizontal rotation, and in conjunction with externally moving steel balls, the rotation of the rolling wheels and steel balls reduces direct friction with the stress source when subjected to lateral external forces. Furthermore, the rolling wheels are detachable, allowing for quick replacement of worn wheels.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A wear-resistant rubber fender includes: a collision part and rolling wheels. The front end of the collision part is embedded with a plurality of hydraulic dampers. The telescopic ends of the hydraulic dampers are all fixedly connected to bearings. A rotating wheel is fixed in the inner ring of each bearing. The upper and lower ends of the rolling wheels are equipped with docking cylinders. Each docking cylinder is provided with a limit component. The docking cylinder is connected to the rotating wheel through the limit component, so that the rolling wheel can rotate horizontally with a fixed position.

[0008] The present invention is further configured such that multiple sets of steel balls are distributed in a ring at equal intervals on the outer side of the rolling wheel, and the steel balls are all rolled and mounted on the surface of the rolling wheel.

[0009] The present invention is further configured such that a soft rubber sleeve is fitted to the outside of the rolling wheel, and the surface of the soft rubber sleeve has perforations so that the steel balls can pass through the perforations.

[0010] The present invention is further configured such that each of the rotating wheels has a limiting slot at one end near the center.

[0011] The present invention is further configured as a limiting component comprising: a T-shaped groove formed at the front end of the docking cylinder; a spring fixedly connected to the transverse groove of the T-shaped groove; a slider fixed to the other end of the spring and slidably mounted in the transverse groove; and limiting blocks, all connected to the surface of the slider and inserted into the limiting slot.

[0012] The present invention is further configured as a limiting component including: a pull plate, which is integrally connected to the front end of the slider and located in the vertical groove of the T-shaped groove.

[0013] The present invention is further configured such that two buffer parts are integrally provided on the rear side of the collision part, and a mounting plate is connected to the rear side of the buffer parts.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. When the rubber fender is subjected to lateral stress, the ship comes into contact with the rolling wheel at the front end of the collision part. The lateral friction causes the rolling wheel to rotate horizontally. At the same time, multiple steel balls are evenly distributed in a ring on the surface of the rolling wheel. The steel balls also rotate under stress. The rotation of the rolling wheel and the steel balls reduces contact friction. When subjected to lateral stress, the wear on the surface can be effectively reduced, further improving the wear resistance.

[0016] 2. The rubber fender is equipped with a limit component inside the docking cylinder. By pulling the pull plate in the limit component, the spring is compressed, which makes the rolling wheel and the two docking cylinders locked between the two rotating wheels. Then, by releasing the pull plate, the spring rebounds and the limit block in the limit component fits into the limit slot on the surface of the rotating wheel, fixing the position of the rolling wheel so that it can rotate horizontally synchronously. This design allows for quick disassembly and replacement when the corresponding rolling wheel is worn. Attached Figure Description

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0027] Reference Figure 1-5 A rubber fender with good wear resistance includes: two buffer parts 1 and one collision part 2. The two buffer parts 1 are integrally connected to the rear side of the collision part 2. The rear side of the two buffer parts 1 is connected to the mounting plate 3. The position of the buffer parts 1 is fixed by fixing the mounting plate 3 to the dock wall.

[0028] Specifically, such as Figure 2 As shown, multiple hydraulic buffers 6 are embedded and fixed at the front end of the collision part 2, and the telescopic ends of the hydraulic buffers 6 are all connected to bearings 7.

[0029] Furthermore, the outer ring of each bearing 7 is integrally connected to a bearing housing, and the bearing housing is fixed to the telescopic end of the hydraulic buffer 6.

[0030] Furthermore, a rotating wheel 8 is fixed in the inner ring of each bearing 7, which can reduce the rotational friction of the rotating wheel 8.

[0031] The device also includes a rolling wheel 4, which is mounted on the front end of the collision part 2.

[0032] Scroll wheel 4 is as follows Figure 3 As shown, multiple steel balls 10 are arranged in a ring at equal intervals on the surface of the rolling wheel 4. All steel balls 10 can rotate on the surface of the rolling wheel 4. At the same time, a soft rubber sleeve 11 is sleeved on the outside of the rolling wheel 4. The surface of the soft rubber sleeve 11 has a through hole to allow the steel balls 10 to pass through.

[0033] In this embodiment, the soft rubber sleeve 11 can protect the surface of the rolling wheel 4.

[0034] like Figure 1 As shown, docking cylinders 5 are integrally connected to both the upper and lower ends of the rolling wheel 4, and the two docking cylinders 5 are symmetrically designed.

[0035] The docking cylinder 5 is equipped with a limit component, as shown in the following figure. Figure 4-5 As shown, T-shaped grooves 12 are provided at the front end of the docking cylinder 5.

[0036] Furthermore, the T-shaped groove 12 is divided into a horizontal groove and a vertical groove. A spring 16 is fixedly connected in the horizontal groove, and the other end of the spring 16 is connected to a slider 14. The slider 14 is slidably installed in the horizontal groove. The front end of the slider 14 is integrally connected to a pull plate 13, which is located in the vertical groove.

[0037] Furthermore, limit blocks 15 are connected to the surface of slider 14.

[0038] Specifically, such as Figure 2 As shown, a limit slot 9 is provided at one end of the rotating wheel 8 near the center.

[0039] In this embodiment, pulling the pull plate 13 causes the slider 14 to compress the spring 16, allowing the docking cylinder 5 to dock with the rotating wheel 8, aligning the limiting block 15 with the limiting slot 9. Then, releasing the pull plate 13 causes the slider 14 to reset under the rebound of the spring 16, allowing the limiting block 15 to fit into the limiting slot 9, thereby simultaneously fixing the position of the rolling wheel 4 between the two docking cylinders 5.

[0040] At the same time, the rolling wheel 4 and the two docking cylinders 5 can rotate synchronously with the rotating wheel 8.

[0041] This design allows for reduced hard friction and improved wear resistance when subjected to lateral stress through the rotation of the roller 4 and the steel balls 10 on the surface of the roller 4. At the same time, worn roller 4 can be quickly disassembled and replaced.

[0042] Working principle: When using this utility model, when subjected to lateral stress, the ship contacts the rolling wheel 4 at the front end of the collision part 2. During the lateral friction, the rolling wheel 4 rotates horizontally. At the same time, multiple steel balls 10 are evenly distributed in a ring on the surface of the rolling wheel 4. The steel balls 10 also rotate under stress. The rotation of the rolling wheel 4 and the steel balls 10 reduces contact friction. When subjected to lateral stress, it can effectively reduce the wear on the surface and further improve wear resistance. Limiting components are set inside the docking cylinders 5. By pulling the pull plate 13 in the limiting component, the spring 16 is compressed, so that the rolling wheel 4 and the two docking cylinders 5 are locked between the two rotating wheels 8. Then, by releasing the pull plate 13, under the rebound of the spring 16, the limiting block 15 in the limiting component is inserted into the limiting slot 9 on the surface of the rotating wheel 8, fixing the position of the rolling wheel 4 so that it can rotate horizontally synchronously. This design allows for quick disassembly and replacement when the corresponding rolling wheel 4 is worn.

[0043] 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.
