Description

Technical Field

[0001] The utility model relates to the technical field of fenders, in particular to an assembled rubber fender structure for offshore wind turbine foundation berthing piles. Background Art

[0002] Rubber fender, also known as rubber fender, is an important anti-collision device installed on docks or ships. Its main function is to absorb the collision energy between the ship and the dock or between the ships when docking or mooring, thereby protecting the ship and the dock from damage.

[0003] Rubber fenders are widely used in ports, docks, offshore drilling platforms and other places. In ship-to-ship, ship-to-dock barge, docking and other occasions, rubber fenders play an important protective role. Common rubber fenders are usually compressed solid rubber fenders, which are a whole rubber block and are usually installed directly on the side of the dock when in use.

[0004] When a common compression-type solid rubber fender is hit by a ship, it will absorb the collision energy between the ship and the dock when docking. Since the collision energy is directly transferred to the rubber fender, and the compressible space of solid rubber is small, when the collision energy is too large, the rubber fender may be greatly deformed, which not only reduces the anti-collision and shock resistance effect, but also shortens its service life. Utility Model Content

[0005] The purpose of this utility model is to provide an assembled rubber fender structure for offshore wind turbine foundation berthing piles to solve the following technical problems:

[0006] How to improve the anti-collision and anti-vibration effect of rubber fenders and extend their service life.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] An assembled rubber fender structure for offshore wind turbine foundations moored by ship piles includes a fixed plate, an outer wall of the fixed plate is provided with a mounting groove, two groups of sliders are slidably connected in the mounting groove, the outer walls of the two groups of sliders are hinged with push rods, the ends of the two groups of push rods away from the sliders are hinged with the mounting plate, the end of the mounting plate away from the fixed plate is clamped with two groups of rubber blocks, and elastic members are fixedly connected between the opposite surfaces of the two groups of sliders and the sliding groove.

[0009] Furthermore, the elastic member includes first springs fixedly connected to opposite surfaces of the two groups of sliders, and the two groups of first springs are fixedly connected to the inner wall of the sliding groove.

[0010] Furthermore, limiting grooves are provided in the fixed plate and on both sides of the slide groove, and the two groups of limiting grooves are symmetrically arranged relative to the slider, and the outer walls of the two groups of sliders are fixedly connected to limiting blocks, and the limiting blocks correspond to the limiting grooves. The limiting blocks are slidably installed in the limiting grooves, and a second spring is fixedly connected between the two adjacent groups of limiting blocks in the limiting grooves.

[0011] Furthermore, two groups of connecting grooves are provided on the top of the mounting plate, and the rubber block is composed of a rectangular block and a fan-shaped block. The rectangular block is located in the connecting groove, and the facing surfaces of the two groups of rectangular blocks are provided with positioning grooves. Slots are provided in the mounting plate and in the two groups of connecting grooves, and the slots correspond to the positioning grooves one-to-one. A third spring is fixedly connected to the two groups of slots, and a positioning block is fixedly connected to one end of the two groups of third springs close to the positioning groove. The positioning block is adapted to the size of the positioning groove, and the positioning block is trapezoidal.

[0012] Furthermore, the inner walls of the two groups of notches on the side away from the positioning grooves are provided with through holes that penetrate the mounting plate, and the outer walls of the two groups of positioning blocks on the side close to the adjacent third springs are fixedly connected with connecting rods, and the two groups of connecting rods are respectively slidably installed in adjacent through holes, and the ends of the two groups of connecting rods away from the positioning blocks are fixedly connected with connecting plates.

[0013] Furthermore, both ends of the top of the mounting plate are fixedly connected to fourth springs, the tops of the two groups of the fourth springs are fixedly connected to driving plates, the bottoms of the opposite ends of the two groups of driving plates are fixedly connected to driving rods, the bottoms of the two groups of driving rods are fixedly connected to trapezoidal blocks, the two groups of trapezoidal blocks are respectively located between the two groups of connecting rods and the mounting plate, and the inclined surfaces of the two groups of trapezoidal blocks are respectively in contact with the side walls of adjacent connecting plates.

[0014] Furthermore, telescopic rods are fixedly connected to the top of the mounting plate and located in the two groups of fourth springs, and the tops of the two groups of telescopic rods are respectively fixedly connected to the lower surfaces of adjacent driving plates.

[0015] Beneficial effects of the utility model:

[0016] (1) The utility model pushes the rubber block and the mounting plate toward the side close to the fixed plate through the ship. During this process, the two sets of push rods push the two sets of sliders toward the two sides of the mounting groove and squeeze the elastic member at the same time. During the compression process, the elastic member can absorb a part of the collision energy, thereby reducing the impact force directly applied by the ship to the rubber block. When the mounting plate is completely fitted with the fixed plate, the remaining collision energy can be absorbed by the deformation of the rubber block, thereby achieving a shock-absorbing and protective effect. Moreover, since the elastic member absorbs a part of the collision energy, the deformation of the rubber block can be reduced, thereby improving the anti-collision and anti-vibration effect and increasing its service life.

[0017] (2) In the present invention, when the slider is driven to move in the installation groove, the limit block will be driven to move synchronously in the limit groove. During this process, the limit block can limit the slider to prevent the slider from being deflected during movement. When the limit block moves, it will stretch the second spring. Through such a setting, the second spring will also consume a certain amount of collision energy during the stretching process, thereby assisting the first spring and the rubber block to consume the collision energy brought by the ship, further improving the anti-collision and anti-seismic effect of the device.

[0018] (3) The utility model presses the driving plate downward, and the driving rod drives the trapezoidal block to move downward and compress the fourth spring. Since the inclined surface of the trapezoidal block contacts the side wall of the adjacent connecting plate, when the trapezoidal block moves downward, it drives the connecting plate to move to the side away from the mounting plate and compresses the third spring, thereby driving the connecting rod and the positioning block to move into the slot. At this time, the positioning block no longer positions and fixes the rubber block, and the rubber block can be directly tilted and removed, which is convenient and quick. In addition, through such a setting, when the staff replaces the rubber block, they can replace it directly on the dock without disassembling the fixing plate, which is convenient and quick, thereby improving the replacement efficiency of the rubber block.

DETAILED DESCRIPTION

[0028] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] An assembled rubber fender structure for offshore wind turbine foundation berthing piles in an embodiment of the utility model;

[0030] Please refer to the attached picture Figure 1 - Figure 7 As shown, it includes a fixed plate 1, the outer wall of which is provided with a mounting groove 2, two groups of sliders 21 are slidably connected in the mounting groove 2, the outer walls of the two groups of sliders 21 are hinged with push rods 23, the ends of the two groups of push rods 23 away from the sliders 21 are hinged with a mounting plate 3, the end of the mounting plate 3 away from the fixed plate 1 is clamped with two groups of rubber blocks 32, and elastic members are fixedly connected between the opposite surfaces of the two groups of sliders 21 and the sliding groove;

[0031] Through the above technical solution, when the fixing plate 1 in this embodiment is used, the fixing plate 1 is first fixed vertically to the side of the dock by bolts. At this time, the distance between the two sets of sliders 21 is small under the action of the elastic member, while the distance between the mounting plate 3 and the fixing plate 1 is relatively large. When the ship is docked, the side of the ship will first contact the rubber block 32, and then push the rubber block 32 and the mounting plate 3 to the side close to the fixing plate 1. During this process, the two sets of push rods 23 will push the two sets of sliders 21 to both sides of the mounting groove 2 and squeeze the elastic member at the same time. The elastic member will be compressed during the compression process. In the process, a part of the collision energy can be absorbed. By so configuring, as the elastic member is continuously squeezed, the collision energy absorbed by it becomes greater, thereby reducing the impact force directly exerted by the ship on the rubber block 32. When the mounting plate 3 is completely in contact with the fixing plate 1, the remaining collision energy can be absorbed by the deformation of the rubber block 32, thereby achieving a shock-absorbing and protective effect, thereby protecting the ship and the dock from damage. Moreover, since the elastic member absorbs a part of the collision energy, the deformation of the rubber block 32 can be reduced, thereby improving the anti-collision and shock-resistant effect and increasing its service life.

[0032] Please refer to the attached picture Figure 1 and Figure 2 As shown, the elastic member includes a first spring 22 fixedly connected to the opposite surfaces of the two groups of sliders 21, and the two groups of the first springs 22 are fixedly connected to the inner wall of the slide groove;

[0033] Through the above technical solution, when the ship squeezes the mounting plate 3 and the rubber block 32, the two sets of sliders 21 will squeeze the first spring 22 respectively. During this process, the first spring 22 can absorb part of the collision energy, and as the first spring 22 continues to be squeezed, the collision energy it absorbs becomes greater, thereby reducing the impact force directly exerted by the ship on the rubber block 32 and improving the anti-collision and anti-vibration effect.

[0034] Please refer to the attached picture Figure 2 and Figure 3 As shown, limiting grooves 24 are provided in the fixing plate 1 and on both sides of the slide groove. The two groups of limiting grooves 24 are symmetrically arranged relative to the slider 21. The outer walls of the two groups of sliders 21 are fixedly connected to limiting blocks 25. The limiting blocks 25 correspond to the limiting grooves 24. The limiting blocks 25 are slidably installed in the limiting grooves 24. A second spring 26 is fixedly connected between two adjacent groups of limiting blocks 25 in the limiting grooves 24.

[0035] Through the above technical solution, when the slider 21 is driven to move in the installation groove 2, it will drive the limit block 25 to move synchronously in the limit groove 24. During this process, the limit block 25 can limit the slider 21 to prevent the slider 21 from deflecting during the movement. When the limit block 25 moves, it will stretch the second spring 26. Through such a setting, the second spring 26 will also consume a certain amount of collision energy during the stretching process, thereby assisting the first spring 22 and the rubber block 32 to consume the collision capacity brought by the ship, further improving the anti-collision and anti-seismic effect of the device.

[0036] Please refer to the attached picture Figure 4 、 Figure 5 and Figure 6 As shown, two groups of connecting grooves 31 are provided on the top of the mounting plate 3, and the rubber block 32 is composed of a rectangular block and a fan-shaped block. The rectangular block is located in the connecting groove 31, and the facing surfaces of the two groups of rectangular blocks are provided with a positioning groove 33. Slots 38 are provided in the mounting plate 3 and in the two groups of connecting grooves 31. The slots 38 correspond to the positioning grooves 33 one-to-one. The two groups of the slots 38 are fixedly connected to the third springs 34. The ends of the two groups of the third springs 34 close to the positioning groove 33 are fixedly connected to the positioning blocks 35. The positioning blocks 35 are adapted to the positioning groove 33 in size and are trapezoidal in shape.

[0037] When the locating groove 33 on the outside of the rectangular block moves to coincide with the groove 38 , the rectangular block no longer squeezes the locating block 35 . At this time, the locating block 35 will be reset under the action of its own elastic restoring force and drive the locating block 35 into the positioning groove 33 , thereby achieving the fixation of the rubber block 32 , which is convenient and quick.

[0038] Please refer to the attached picture Figure 5 and Figure 6 As shown, the inner wall of the two groups of notches 38 away from the positioning groove 33 is provided with a through hole penetrating the mounting plate 3, and the outer wall of the two groups of positioning blocks 35 close to the adjacent third spring 34 is fixedly connected to a connecting rod 36. The two groups of connecting rods 36 are slidably installed in the adjacent through holes, and the ends of the two groups of connecting rods 36 away from the positioning blocks 35 are fixedly connected to a connecting plate 37.

[0039] Through the above technical solution, when the rubber block 32 needs to be replaced after long-term use, it is only necessary to pull the two sets of connecting plates 37 to the side away from the mounting plate 3 to drive the connecting rod 36 and the positioning block 35 to move into the slot 38. At this time, the positioning block 35 no longer positions and fixes the rubber block 32, and the rubber block 32 can be directly removed at an angle, which is convenient and quick.

[0040] Please refer to the attached picture Figure 5 and Figure 7 As shown, both ends of the top of the mounting plate 3 are fixedly connected to fourth springs 41, the tops of the two groups of the fourth springs 41 are fixedly connected to the driving plate 4, the bottoms of the opposite ends of the two groups of the driving plates 4 are fixedly connected to driving rods 43, the bottoms of the two groups of the driving rods 43 are fixedly connected to trapezoidal blocks 44, the two groups of the trapezoidal blocks 44 are respectively located between the two groups of connecting rods 36 and the mounting plate 3, and the inclined surfaces of the two groups of the trapezoidal blocks 44 are respectively in contact with the side walls of the adjacent connecting plates 37;

[0041] With the above technical solution, when the rubber block 32 needs to be replaced after being used for a long time, it is only necessary to press the driving plate 4 downward. At this time, the driving rod 43 will drive the trapezoidal block 44 to move downward and compress the fourth spring 41. Since the inclined surface of the trapezoidal block 44 contacts the side wall of the adjacent connecting plate 37, when the trapezoidal block 44 moves downward, it will drive the connecting plate 37 to move to the side away from the mounting plate 3 and compress the third spring 34, thereby driving the connecting rod 36 and the positioning block 35 to move into the notch 38. At this time, the positioning block 35 no longer positions and fixes the rubber block 32, and can be directly The rubber block 32 can be removed at an angle, which is convenient and quick. With such an arrangement, the staff can replace the rubber block 32 directly on the dock without having to disassemble the fixing plate 1. This is convenient and quick, and improves the replacement efficiency of the rubber block 32. After the replacement is completed, the driving plate 4 will be reset under the elastic restoring force of the fourth spring 41 itself, and will no longer position the connecting plate 37, so that the connecting plate 37 and the positioning block 35 can be reset under the elastic force of the third spring 34 itself, which is convenient for the subsequent fixation of the newly replaced rubber block 32.

[0042] Please refer to the attached picture Figure 5 and Figure 7 As shown, the top of the mounting plate 3 and the two sets of fourth springs 41 are fixedly connected with telescopic rods 42, and the tops of the two sets of telescopic rods 42 are respectively fixedly connected to the lower surfaces of the adjacent driving plates 4;

[0043] Through the above technical solution, when replacing the rubber block 32, it is necessary to press down the driving plate 4. At this time, the telescopic rod 42 will be extended and retracted synchronously. The telescopic rod 42 can limit the driving plate 4 to ensure that it will not be offset in position during the pressing process, thereby ensuring that the position of the trapezoidal block 44 will not be offset, so that the trapezoidal block 44 can stably drive the connecting plate 37.

[0044] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
