Description

Technical Field

[0001] The utility model relates to the technical field of ship fenders, in particular to a ship rubber fender with a stable structure. Background Art

[0002] Rubber fenders are installed on docks or ships to absorb the collision energy between ships and docks or between ships when docking or mooring, and protect ships and docks from damage. They are usually connected to the structure with bolts. Among them, D-type rubber fenders are the most commonly used rubber fenders.

[0003] It has been found in actual use that the existing rubber fenders have the following deficiencies:

[0004] Most of the current D-shaped rubber fenders are installed and fixed by bolts passing through the D-shaped cavity to the outside, or by adding extensions to the D-shaped rubber fender itself and then fixing them with bolts. In this connection structure, after a collision, the bolts, which are the components that fix the rubber fender, are directly pulled by the rubber fender. The force applied to the rubber fender directly acts on the bolts, and the stress on the roots of the bolts is relatively strong, making the bolts more likely to break, affecting the stability of the rubber fender during operation.

[0005] In addition, the existing rubber fender is the main force-bearing part. The internal hollow structure of the rubber fender is designed to cushion deformation. However, it is often hit by ships. When the impact force on the rubber fender is overloaded, it is easy to cause the cushioning capacity of the rubber fender to decrease, which may affect the safety of the ship docking.

[0006] Therefore, the present application provides a rubber fender with a stable structure for use on a ship to meet the demand. Utility Model Content

[0007] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology and to propose a rubber fender for a ship with a stable structure.

[0008] The technical problem to be solved by the utility model is to provide a rubber fender for a ship with a stable structure to solve the problems of the existing rubber fender for a ship with a stable structure.

[0009] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0010] A marine rubber fender with a stable structure comprises: a fender frame, a D-shaped rubber fender, a connecting rib, a fixing rib, a supporting rib, a protective cover, bolts and nuts. The D-shaped rubber fender is mounted on the fender frame, a surface of the D-shaped rubber fender is provided with a plurality of energy-absorbing holes, a back surface of the D-shaped rubber fender is provided with a plurality of mounting grooves, an outer end of the D-shaped rubber fender is mounted with a connecting rib, a side surface of the connecting rib is connected to a fixing rib, a surface of the fixing rib is provided with a movable groove, a side surface of the fixing rib is connected to a supporting rib, a protective cover is mounted in the movable groove of the fixing rib, a bolt is mounted inside the protective cover, and a nut is mounted on the outer end of the bolt.

[0011] Preferably, two groups of the connecting ribs and the fixing ribs are provided, and the two groups of the connecting ribs and the fixing ribs are respectively installed on the left and right sides of the interior of the D-shaped rubber fender.

[0012] Preferably, the connecting ribs and the fixing ribs are both rectangular, and the connecting ribs are located outside the D-shaped rubber fender, with a gap between the fixing ribs and the side opening of the D-shaped rubber fender.

[0013] Preferably, the connecting ribs and the fixing ribs are in a T-shape as a whole, and the fixing ribs extend inwardly to the interior of the D-shaped rubber fender and fit on the surface of the D-shaped rubber fender.

[0014] Preferably, the bolts sequentially penetrate the protective sleeve, the mounting groove and the fender frame into the wall, and the D-shaped rubber fender is mounted on the fender frame through a fixing rib.

[0015] Preferably, the movable groove is in the shape of a rectangular strip, and the protective sleeve is in the shape of a "T", and the outer end of the protective sleeve is tightly pressed against the outer end of the edge of the movable groove through a nut.

[0016] Preferably, the D-shaped rubber fender is movably connected to the fixed rib and the fender frame through a protective sleeve, bolts and nuts.

[0017] Preferably, both upper and lower ends of the fixed rib are connected to supporting ribs, the supporting rib is rectangular, and the other end of the supporting rib rests on the inner wall of the D-shaped rubber fender.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] 1. The D-type rubber fender is always kept between the fixed ribs and the fender frame. When subjected to lateral collision and extrusion, the D-type rubber fender can be fixed between the fixed ribs and the fender frame while moving laterally along the movable groove. This not only reduces the rigid interaction force after the collision, but also reduces the force on the bolts caused by the collision through the displacement of the D-type rubber fender, thereby reducing the stress at the root and ensuring the stability of the rubber fender during operation. 2. Support ribs are connected to the upper and lower ends of the fixed ribs, and the other ends of the support ribs rest on the inner wall of the D-type rubber fender. When the D-type rubber fender is subjected to a head-on collision, the D-type rubber fender is squeezed inward and deformed. The pressure is transmitted to the support ribs, and the support ribs supported on the inner walls of the upper and lower ends of the D-type rubber fender are compressed and deformed inside the D-type rubber fender. The elastic force relieves part of the impact force of the ship on the rubber fender, reduces the force acting on the rubber fender, and can improve the overall anti-seismic energy absorption effect.

The D-shaped rubber fender 2 is mounted on the fender frame 1, a surface of the D-shaped rubber fender 2 is provided with a plurality of energy-absorbing holes 201, a back surface of the D-shaped rubber fender 2 is provided with a plurality of mounting grooves 202, a connecting rib 3 is mounted on the outer end of the D-shaped rubber fender 2, a side surface of the connecting rib 3 is connected to the fixing rib 4, a surface surface of the fixing rib 4 is provided with a movable groove 401, a side surface of the fixing rib 4 is connected to the supporting rib 5, a protective cover 6 is mounted in the movable groove 401 of the fixing rib 4, a bolt 7 is mounted inside the protective cover 6, and a nut 8 is mounted on the outer end of the bolt 7.

[0029] In this embodiment, two groups of connecting ribs 3 and fixing ribs 4 are provided. The two groups of connecting ribs 3 and fixing ribs 4 are respectively installed on the left and right sides of the interior of the D-shaped rubber fender 2. The two groups of connecting ribs 3 and fixing ribs 4 can fix the two ends of the D-shaped rubber fender 2.

[0030] In this embodiment, the connecting ribs 3 and the fixed ribs 4 are both rectangular in shape, and the connecting ribs 3 are located on the outside of the D-shaped rubber fender 2. There is a gap between the fixed ribs 4 and the side opening of the D-shaped rubber fender 2. The connecting ribs 3 can limit the side of the D-shaped rubber fender 2 to prevent excessive lateral displacement of the D-shaped rubber fender 2.

[0031] In this embodiment, the connecting ribs 3 and the fixing ribs 4 are in a "T" shape as a whole, and the fixing ribs 4 extend inwardly to the interior of the D-shaped rubber fender 2 and fit on the surface of the D-shaped rubber fender 2, so that the connecting ribs 3 and the fixing ribs 4 can maintain the same direction with the D-shaped rubber fender 2.

[0032] In this embodiment, the bolt 7 passes through the protective cover 6 , the mounting groove 202 and the fender frame 1 in sequence and penetrates into the wall, and the D-shaped rubber fender 2 is mounted on the fender frame 1 through the fixing rib 4 .

[0033] In this embodiment, the movable groove 401 is in the shape of a rectangular strip, and the protective cover 6 is in the shape of a "T". The outer end of the protective cover 6 is tightly pressed against the outer end of the edge of the movable groove 401 by the nut 8, so that the D-shaped rubber fender 2 is always maintained between the fixed rib 4 and the fender frame 1.

[0034] In this embodiment, the D-shaped rubber fender 2 is movably connected to the fixed rib 4 and the fender frame 1 via a protective sleeve 6, a bolt 7, and a nut 8. When subjected to lateral collision and extrusion, the D-shaped rubber fender 2 can be laterally displaced along the movable groove 401 while being fixed between the fixed rib 4 and the fender frame 1. This not only reduces the rigid force of the interaction after the collision, but also reduces the force acting on the bolt 7 through the displacement of the D-shaped rubber fender 2, thereby reducing the stress at its root and ensuring its stability during operation.

[0035] In this embodiment, the upper and lower ends of the fixed rib 4 are connected to supporting ribs 5, which are rectangular in shape, and the other end of the supporting rib 5 rests on the inner wall of the D-shaped rubber fender 2. By connecting the supporting ribs 5 to the upper and lower ends of the fixed rib 4, when the D-shaped rubber fender 2 is subjected to a head-on collision, the D-shaped rubber fender 2 is squeezed inward and deformed, and the pressure is transmitted to the supporting ribs 5. The supporting ribs 5 supported on the inner walls of the upper and lower ends of the D-shaped rubber fender 2 are compressed and deformed inside the D-shaped rubber fender 2, and the elastic force is used to alleviate part of the impact force of the ship on the rubber fender, reduce the force acting on the rubber fender, and improve the overall anti-seismic energy absorption effect.
