Description

Technical Field

[0001] This invention relates to an ultra-large conical rubber fender, specifically to an ultra-large conical rubber fender and its installation method. Background Technology

[0002] Extra-large tapered rubber fenders are fender systems used on ships and docks. They are made of large pieces of rubber and are typically tapered or elliptical in shape. These fenders are installed on the edge of a dock or ship to mitigate impacts and collisions between the vessel and the dock, protecting the hull and dock structure from damage.

[0003] Publication (Announcement) No.: CN101148192A, Publication (Announcement) Date: 2008-03-26, discloses a large conical rubber fender and its manufacturing method. The problem to be solved is the existing issue in the background technology: fenders made of wooden piles easily waste timber and installation manpower, while fenders made of waste tires do not have good bending and shear resistance. The key points of the technical solution adopted to solve this technical problem are: pre-embedded nuts and pre-embedded frame steel plates are set on the front plane of the hollow conical rubber body, and bolt holes are set on the rear plane. The manufacturing method of this fender is as follows: A. Cut the steel plate, sandblast to remove rust, apply metal adhesive, and coat the steel plate with rubber for later use; B. Using raw rubber as the main component (50%–58%, vulcanization accelerator 2%–2.6%, carbon black 35%–50%, softener 3%–5%, antioxidant 2%–3%), plasticize and mix the raw rubber, then co-extrude it with the skeleton steel plate obtained in step A using a dual extruder, vulcanize, remove the film, repair, and store it. This invention can be used for impact protection of berths and ships, and has good stiffness, bending and shear strength, corrosion and aging resistance, and resource conservation.

[0004] In the prior art, including the aforementioned patents, traditional large conical rubber fenders are formed by combining pre-embedded steel plates and injection-molded parts. The soft contact capability provided for ship berthing relies entirely on the damping force that the injection-molded parts can provide. Therefore, the soft contact capability of large conical rubber fenders is limited by the current level of material development. Summary of the Invention

[0038] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] like Figure 1-5 As shown, an ultra-large conical rubber fender includes an installation part 1, a side enclosure part 2 is provided on the installation part 1, and a neck enclosure part 3 that is kept active by a resistance spring 9 is movably provided on the side enclosure part 2.

[0040] The mounting part 1 is provided with a load-bearing buffer assembly 4 located inside the perimeter part 2. The load-bearing buffer assembly 4 includes a frustum-shaped connecting part 41.

[0041] It also includes a force-bearing part 5, which is attached to the connecting part 41 and is extended beyond the predetermined length of the neck part 3 port in the default state.

[0042] Specifically, in the above embodiment, when the force-bearing part 5 is subjected to force, it will move toward the mounting part 1. At this time, the bearing buffer assembly 4 is deformed by force, so that the force-bearing part 5 abuts against the port of the neck part 3, and the neck part 3 is moved by the force-bearing part 5. At this time, the damping spring 9 is deformed, and the damping force of the bearing buffer assembly 4 and the damping spring 9 increases.

[0043] The connecting part 41 of the frustum-shaped structure in the above embodiment is specifically a hollow structure and is made of rubber material. When the force-bearing part 5 is subjected to force, the connecting part 41 will shrink in the radial direction and deform itself.

[0044] In the above technology, the ultra-large conical rubber fender, which is integrally plastically formed, is modularly combined. The elastic expansion and contraction of the force-bearing part 5 and the load-bearing buffer component 4, and the deformation of the load-bearing buffer component 4 into a predetermined state, cause the force-bearing part 5 to be subjected to force on the neck part 3, and the neck part 3 and the side part 2 are elastically expanded and contracted.

[0045] As a further embodiment of the present invention, the force-bearing part 5 is specifically a hollow structure, and a first buffer member 51 arranged in a linear array is provided in the hollow structure. The first buffer member 51 has an X-shaped structure.

[0046] Specifically, in this embodiment, the force-bearing part 5 is a hollow structure, and the first buffer 51 has an X-shaped structure. This can offset the compressive force caused by the ship's instantaneous contact with the force-bearing part 5.

[0047] As a further embodiment of the present invention, the mounting part 1 is provided with a protective enclosure 6, which is arranged at an angle and connected to the end of the neck enclosure 3 to form a sealed cavity 61 filled with gas to a predetermined density; at least three sets of elastic columns 62 arranged in a circumferential array are provided between the protective enclosure 6 and the side enclosure 2.

[0048] Specifically, in this embodiment, the increased lateral force on the protective enclosure 6 is achieved by utilizing the inflatable sealing cavity 61 to increase the damping force of the protective enclosure 6. Simultaneously, multiple elastic pillars 62 can cooperate with the sealing cavity to provide good damping force. Furthermore, the above structure can increase the damping force on the neck enclosure 3, and together with the load-bearing buffer assembly 4 and the retaining spring 9, increase the damping force.

[0049] As a further embodiment of the present invention, the connecting part 41 of the frustum-shaped structure has a stepped wall 42 on its side wall. When the force-bearing part 5 moves toward the mounting part 1 under force, the upper step of the stepped wall 42 will sit on the lower step to form a stack so that the downward damping force increases.

[0050] Specifically, in the above embodiment, the sidewall of the connecting part 41 is stepped, that is, stepped wall 42, and the narrow opening contacts the force-bearing part 5. Therefore, when the force causes contraction in the radial direction, the upper step of the stepped wall 42 will sit on the lower step to form a stack, thereby optimizing the damping force that the bearing buffer assembly 4 can provide.

[0051] As another embodiment of the present invention, the connecting part 41 is composed of a plurality of side lobe circumferential arrays, and a buffer 7 is provided between each side lobe, and the buffer 7 is provided on each level of the stepped wall 42.

[0052] In the above embodiment, the connecting part 41 is composed of multiple side lobes. Therefore, when the connecting part 41 is subjected to force and shrinks in the radial direction, the upper level of the stepped wall 42 will sit on the lower level to form a stack. During this process, the gap between every two side lobes will shrink, thereby squeezing the buffer 7 and further optimizing the damping force that the bearing buffer assembly 4 can provide.

[0053] The buffer 7 mentioned above can be a rubber elastic column, an elastic metal plate, or any elastic component known to those skilled in the art.

[0054] As a further preferred embodiment of the present invention, the buffer 7 includes symmetrically arranged connecting portions 71 and a first V-shaped member 72 and a second V-shaped member 73 disposed between the two connecting portions 71, wherein:

[0055] The tops of the first V-shaped member 72 and the second V-shaped member 73 are arranged opposite each other, and the second V-shaped member 73 passes through the slot opened on the first V-shaped member 72, and its sidewall does not contact the slot.

[0056] Specifically, in the embodiment, when the connecting part 41 contracts in the radial direction under force, the upper step of the stepped wall 42 will sit on the lower step to form a stack, and the gap between every two side lobes will shrink. At this time, the ports of the first V-shaped member 72 and the second V-shaped member 73 will shrink, and each step on the stepped wall 42 is equipped with a buffer member 7, which can increase the damping force that the load-bearing buffer assembly 4 can provide.

[0057] As another embodiment of the present invention, a triangular combination frame 8 is provided on the mounting part 1, and the triangular combination frame 8 includes two side wall parts 81 arranged at an angle.

[0058] It also includes multiple connecting rods 82, one end of which is installed on each step of the stepped wall 42 of the connecting part 41, and the other end is directly connected to the side wall part 81.

[0059] Specifically, in this embodiment, the connecting rod 82 is a rigid rubber rod with an internal iron rod. When each step of the stepped wall 42 moves down, the force is transmitted to the side wall portion 81 through the connecting rod 82, and the two side wall portions 81 and the mounting portion 1 form a triangular structure. This increases the reaction force on the stepped wall 42, thereby increasing the damping force that the load-bearing buffer assembly 4 can provide.

[0060] As a further embodiment of the present invention, a second buffer 83 is provided between each pair of adjacent connecting rods 82, and the second buffer 83 has an X-shaped structure.

[0061] Specifically, in this embodiment, each connecting rod 82 is connected in series through the second buffer 83. Therefore, when the upper level of the stepped wall 42 deforms, the corresponding connecting rod 82 will transmit the force to the multiple connecting rods 82 below, and then to the other steps of the stepped wall 42, thereby achieving the effect of uniform force rather than increasing damping force. The maximum damping effect is achieved by uniformly distributing the force on each step of the stepped wall 42.

[0062] As a further preferred embodiment of the present invention, the triangular combination frame 8 also includes a third buffer 84, which is installed between the ends of the two side wall portions 81.

[0063] The third buffer 84 includes a plurality of elastic guide posts 841 arranged in a linear array;

[0064] The elastic guide post 841 is specifically a hollow structure, and the hollow structure is provided with at least an outer ring wire harness group 842 and an inner and outer ring wire harness group 843 arranged in a nested manner.

[0065] Both the outer wire harness group 842 and the inner and outer wire harness groups 843 are composed of multiple circular tough steel bars arranged in a circumferential array, wherein:

[0066] The outer wire harness assembly 842 is provided with a plurality of recesses 844 that protrude toward the inner and outer wire harness assemblies 843, while the inner and outer wire harness assemblies 843 are provided with a plurality of protrusions 845 that protrude toward the recesses 844. When the two ends of the elastic guide post 841 are pressed toward the center by force, the recesses 844 and the protrusions 845 abut against each other.

[0067] Specifically, in the above embodiment, when the connecting part 41 contracts in the radial direction under force, the upper step of the stepped wall 42 sits on the lower step to form a stack. During this process, the gap between every two side lobes narrows, and the ports of the first V-shaped member 72 and the second V-shaped member 73 contract. Furthermore, since each connecting rod 82 is connected in series through the second buffer member 83, when the upper step of the stepped wall 42 deforms, the corresponding connecting rod 82 transmits the force to the lower connecting rods 82, and then to the other steps of the stepped wall 42.

[0068] Furthermore, when the connecting rod 82 is moved under force, it drives the end of the side wall portion 81 to move closer together, which in turn causes the elastic guide post 841 to contract along the axial direction. At this time, the outer coil harness assembly 842 and the inner and outer coil harness assemblies 843 deform, and the recessed portion 844 and the protruding portion 845 come into contact. When the end of the side wall portion 81 moves closer together, the first arched member 85 provided between the side wall portion 81 and the force-bearing portion 5 deforms, that is, the two first arched members 85 move closer together. At this time, the second arched member 86 connecting the two first arched members 875 deforms again, providing damping force.
