Description

Technical Field

[0001] The utility model relates to the technical field of ship fenders, in particular to a ship fender with convenient replacement. Background Technique

[0002] A ship fender refers to a facility installed on the side of a ship and the shore, mainly used to protect the ship from colliding with the shore and being damaged when docking.

[0003] The published patent No. CN213735466U discloses a new type of anti-collision rubber fender for ships, which includes a bearing plate, a fender plate, a buffer plate, a fixing block and a support plate. The fender plate is in an arch structure, and a bearing plate is arranged on the top surface of the fender plate. A plurality of support rods are evenly distributed on the surface of the bearing plate facing the fender plate. One end of each of the plurality of support rods away from the bearing plate movably penetrates through the fender plate and is fixedly connected to the support plate. The support plate is arranged parallel to the bearing plate, and a buffer plate is arranged on the bottom surface of the support plate. A plurality of limiting rods are arranged in an array on the surface of the buffer plate facing the support plate. One end of each of the plurality of limiting rods away from the buffer plate movably penetrates through the support plate; fixing blocks are fixedly connected to the outer walls of the plurality of support rods, and symmetrically distributed telescopic rods are hinged to both ends of the fixing block. This new type of anti-collision rubber fender for ships has a stable structure and good protection performance, and can be widely used. Although this type of ship fender has achieved the effects of stable structure and good protection performance, it lacks in the aspect of cushion replacement. Since the cushion of this type of ship fender is integrally designed with the fender body, its surface will be worn after long-term use. When the cushion is severely worn and needs to be replaced, it can only be replaced together with the fender body, which not only increases the use cost but also reduces the maintenance efficiency.

Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1

[0024] Please refer to Figures 1-4, the present utility model provides a technical solution: a ship fender with convenient replacement, including a mounting plate 1, a bolt 2 is inserted on the surface of the mounting plate 1, a soft block 3 is fixedly installed on the surface of the mounting plate 1, a column 5 is fixedly installed on the surface of the mounting plate 1, a slide bar 6 is slidably connected inside the column 5, a spring 7 is sleeved on the surface of the slide bar 6, one end of the spring 7 is connected to the surface of the column 5, and the other end is connected to the surface of the top plate 4. The design of the spring 7 plays a role in supporting the top plate 4 when the top plate 4 is under pressure, thereby buffering and protecting the ship's hull. A top plate 4 is fixedly installed on the surface of the slide bar 6, the soft block 3 is fixed to the top plate 4, a card slot 8 is penetrated on the surface of the top plate 4, a limit hole 9 is penetrated on the surface of the top plate 4, a limit rod 10 is inserted into the limit hole 9, a fixing plate 11 is fixedly installed on the surface of the limit rod 10, a soft pad 13 is fixedly installed on the surface of the fixing plate 11. The materials of the soft pad 13 and the soft block 3 are both natural rubber. The design of the natural rubber material of the soft pad 13 plays a role in protecting the ship's hull, thereby preventing the situation that the side of the ship's hull is scratched when the ship docks. The design of the natural rubber material of the soft block 3 plays a role in buffering and protecting the extrusion force when the ship docks. A clamping block 12 is fixedly installed on the surface of the fixing plate 11, the clamping block 12 is slidably connected with the card slot 8, an insertion bar 14 is inserted into the top plate 4, the insertion bar 14 is slidably connected with the clamping block 12. The sliding design of the insertion bar 14 and the clamping block 12 plays a role in fixing the clamping block 12 in the card slot 8, thereby fixing the fixing plate 11 and the soft pad 13 on the surface of the top plate 4 through the clamping block 12 and the insertion bar 14. A rotating block 15 is threadedly connected to the surface of the insertion bar 14.

[0025] Embodiment Two

[0026] Please refer to Figures 1-4 , a chute 16 is opened on the surface of the mounting plate 1, a rotating rod 17 is rotatably connected inside the mounting plate 1, the rotating rod 17 is slidably connected with the chute 16, and the sliding design of the rotating rod 17 and the chute 16 plays a role in facilitating the rotation of the rotating rod 17. A roller 18 is rotatably connected to the surface of the rotating rod 17. The design of the rotating rod 17 and the roller 18 plays a role in limiting the top plate 4. The number of the rollers 18 and the rotating rods 17 is two groups, and the two groups of rollers 18 and rotating rods 17 are symmetrically distributed on the surface of the mounting plate 1. The symmetrical design of the rollers 18 and the rotating rods 17 plays a role in limiting the top plate 4, thereby avoiding the situation that the top plate 4 falls off into the water due to excessive pressure. A limit groove 19 is opened on the surface of the top plate 4, and the roller 18 is rollingly connected with the limit groove 19. The rolling design of the roller 18 and the limit groove 19 plays a role in limiting the rotating rod 17.

[0027] Working principle: When using the ship fender, the fixed plate 11 and the soft pad 13 will drive the top plate 4 to move inward under pressure. The top plate 4 will drive the sliding rod 6 to slide into the cylinder 5. At this time, the soft block 3 and the spring 7 will support and buffer the pressure. When it is necessary to replace the soft pad 13, just rotate the rotating block 15. After the rotating block 15 rotates away from the inserting strip 14, the inserting strip 14 can be pulled out from the top plate 4. At this time, the worn soft pad 13 and the fixed plate 11 can be taken out from the top plate 4. Then insert the new soft pad 13 and the fixed plate 11 on the top plate 4. At this time, the fixed plate 11 will drive the limiting rod 10 to be inserted into the limiting hole 9, and at the same time, it will also drive the clamping block 12 to be inserted into the clamping groove 8. At this time, insert it into the top plate 4 again. The inserting strip 14 will slide inside the clamping block 12. After inserting the inserting strip 14, fix the rotating block 15 and the inserting strip 14 by threads. After fixing the rotating block 15, the installation of the soft pad 13 can be completed. The fixed plate 11, the clamping block 12, the top plate 4, the clamping groove 8, the inserting strip 14 and the rotating block 15 play the role of facilitating the disassembly, assembly and replacement of the soft pad 13 and the fixed plate 11, thus avoiding the situation that the ship fender body needs to be replaced together when the soft pad 13 is severely worn, reducing the maintenance cost and improving the maintenance efficiency at the same time. When the top plate 4 moves inward under pressure, it will drive the rotating rod 17 to rotate inside the mounting plate 1. When the rotating rod 17 rotates, it will drive the roller 18 to roll inside the limiting groove 19. At the same time, the rotating rod 17 will also slide inside the sliding groove 16. The sliding groove 16, the limiting groove 19, the rotating rod 17 and the roller 18 play the role of limiting the top plate 4, avoiding the situation that the top plate 4 falls off and drops into the water due to excessive pressure on the top plate 4, thus facilitating the maintenance personnel to maintain and repair the top plate 4.

[0028] The above is only the preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
