Description

Technical Field

[0001] The utility model relates to a fixing and installing structure of a ship fender, in particular to a fixing and installing structure of a rectangular rubber fender for a bow of a ship. Background Art

[0002] Wind power operation and maintenance vessels are special ships designed for the operation and maintenance of offshore wind turbines. In areas with abundant wind resources, severe sea conditions pose a challenge to ships berthing at wind turbine tower piles. During the berthing process, ships are often affected by strong winds, huge waves and rapids, causing severe roll, pitch and heave. In order to improve boarding reliability and operational safety, the key is to increase the friction between the bow and the wind turbine tower piles to reduce the vertical swing of the bow. At present, the common solution is to increase the contact area of ​​the rubber berthing fender. For example Figure 1 As shown, the rubber fender 1A typically adopts a one-piece, rectangular design and is secured via bolts 2A that penetrate the hull structure and the rubber fender. However, this through-the-shoulder installation method damages the rubber fender's overall structure, reducing its impact resistance and increasing the loads on the rubber fender and hull structure, thereby increasing the risk of damage to the rubber fender and the structure. Furthermore, the bolts may twist within the rubber fender when impacted, making replacement and removal more difficult. Utility Model Content

[0003] The utility model provides a simple-structured fixed installation structure for a rectangular rubber fender for a ship, which aims to protect the integrity of the rubber fender, reduce stress and deformation, and facilitate maintenance and replacement.

[0004] The rectangular rubber fender fixing and installation structure for a ship of the utility model comprises fender plates extending outwardly from the upper and lower sides of the bow of the hull for clamping and installing the rubber fender, and the fender plates are provided with a plurality of fixing members passing through the fender plates and in close contact with the upper and lower sides of the rubber fender.

[0005] The above-described marine rectangular rubber fender fixing and installation structure has a plurality of fixing members arranged on both the upper and lower fender plates. The fixing members pass through the fender plates and are in close contact with the upper and lower sides of the rubber fender, thereby achieving all-round positional fixation of the rubber fender in the upper and lower directions, the left and right directions, and the rear direction, thereby effectively preventing the displacement of the rubber fender in the front-back and left-right directions. Since the contact area between the fixing members and the rubber fender is small and they do not penetrate the interior of the rubber fender, the force transmission is more continuous, local deformation is reduced, and the risk of deformation caused by penetrating the interior of the rubber fender is avoided. This reduces the wear of the rubber fender during use and also facilitates future disassembly and maintenance.

[0006] As a preferred solution of the present invention, the fixing member includes a nut embedded in the side of the rubber fender and a bolt passing through the fender plate and screwed to the nut.

[0007] As a preferred solution of the present invention, a groove for fixing a mounting nut is left on the side of the rubber fender.

[0008] As a preferred solution of the present invention, the fixing member includes a back plate located between the fender and the rubber fender and a bolt passing through the fender and tightly abutting the back plate. The side of the back plate in contact with the rubber fender is provided with stripes. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the accompanying drawings 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.

[0016] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0017] If there are descriptions involving "first" or "second" in the embodiments of the present invention, the descriptions of "first" or "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" can explicitly or implicitly include at least one of such features. In addition, the technical features of each embodiment can be arbitrarily combined. In order to make the description concise, not all possible combinations of the technical features in the embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0018] like Figure 2-6 As shown, a rectangular rubber fender fixing and installation structure for a ship includes fender plates extending outward from the upper and lower sides of the bow of the ship for clamping and installing the rubber fender. The fender plates are provided with multiple fixings that pass through the fender plates and closely contact the upper and lower sides of the rubber fender. By distributing multiple fixings on both the upper and lower fender plates, the fixings pass through the fender plates and closely contact the upper and lower sides of the rubber fender, and thus achieve all-round positional fixation of the rubber fender in the upper, lower, left, right, and rear directions, effectively preventing displacement of the rubber fender in the front-back and left-right directions. Because the contact area between the fixings and the rubber fender is small and they do not penetrate the interior of the rubber fender, force transmission is more continuous, reducing local deformation and avoiding the risk of deformation caused by penetrating the interior of the rubber fender. This reduces wear and tear of the rubber fender during use, while also facilitating future disassembly and maintenance.

[0019] The fixing member 3 includes a nut 301 embedded in the side of the rubber fender and a bolt 302 passing through the fender plate and screwed to the nut. The bolt passes through the fender plate and is connected to the nut embedded in the rubber fender, together providing the groove-shaped hull structure with upper and lower, left and right and rearward positioning and fixation of the rubber fender. Since the contact area between the nut and the rubber fender is small, the risk of deformation inside the rubber fender is reduced, and future disassembly and maintenance work is facilitated.

[0020] Furthermore, a groove 101 for fixing the mounting nut is reserved on the side of the rubber fender. By providing the groove for fixing the mounting nut, the connection stability between the rubber fender and the bolt can be enhanced, and the rubber fender can be prevented from sliding or falling off.

[0021] The fixing member 3 includes a back plate 303 positioned between the fender plate and the rubber fender, and bolts 302 that pass through the fender plate and tightly abut the back plate. The back plate's surface in contact with the rubber fender is provided with stripes. Specifically, there are multiple bolts. The back plate can be a single piece or multiple pieces. The back plate is provided between the fender plate and the rubber fender to ensure a secure connection between them. The bolts pass through the fender plate and abut the back plate, utilizing the force generated by the tightening and the stripes on the back plate to increase friction, effectively limiting the forward and backward sliding of the rubber fender. Furthermore, the large contact area between the back plate and the rubber fender helps disperse and absorb impact forces generated when a vessel is berthing or conducting offshore operations, better protecting the structural integrity of the rubber fender while reducing the risk of internal deformation of the rubber fender.

[0022] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made based on the contents of the present invention specification and drawings, or direct / indirect application in other related technical fields, are included in the patent protection scope of the present invention.

[0023] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. In addition, the embodiments of the present invention and the features of the embodiments can be combined with each other unless there is a conflict.
