Description

Technical Field

[0001] The utility model belongs to the technical field of ships, and in particular relates to a fender connection structure for aluminum alloy ships. Background Art

[0002] Fenders are elastic buffer devices used on the edge of ships. They are mainly used to reduce the impact force between the ship and the dock or between ships during docking or mooring, reducing or eliminating damage to the ship and the dock. Therefore, they are widely used.

[0003] At present, when some aluminum alloy ships are equipped with fenders around them, if the traditional aluminum welding method is used, the structural strength is insufficient, it is easy to deform during collision, and maintenance is more difficult. If lightweight EVA glue is used to stick the fenders, it is easy to fall off partially and the entire ship needs to be separately proofed, which is costly and not durable. Therefore, how to improve the fender strength of aluminum alloy ships, reduce maintenance costs, and facilitate installation has become a technical problem that needs to be solved.

[0016] Figure 1 The figure is a schematic diagram of a fender connection structure for an aluminum alloy ship according to an embodiment of the present invention. DETAILED DESCRIPTION

[0017] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the present invention is described in detail below with reference to the embodiments.

[0018] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0019] Please refer to Figure 1 As shown, a fender connection structure 100 for an aluminum alloy ship includes a ship outer plate 1, a rubber fender 2, an aluminum alloy sleeve 3, a bolt 4, a nut 5 and a gasket 6.

[0020] The rubber fender 2 is provided with a ferrule groove 21 , a screw through hole 22 and a nut groove 23 which are sequentially connected along the first direction X. The side of the rubber fender 2 where the nut groove 23 is provided is placed against the ship outer plate 1 .

[0021] The aluminum alloy ferrule 3 is welded and fixed on the outer plate 1 of the ship along the first direction X, and the aluminum alloy ferrule 3 is arranged in the ferrule groove 21.

[0022] The head of the bolt 4 is non-rotatably embedded in the aluminum alloy ferrule 3 , and the screw of the bolt 4 passes through one side of the aluminum alloy ferrule 3 and the screw through hole 22 and then enters the nut groove 23 .

[0023] The backing plate 6 is sleeved on the screw rod of the bolt 4 , the backing plate 6 is attached to the bottom of the ferrule groove 21 , and the backing plate 6 covers the screw rod through hole 22 .

[0024] The nut 5 is sleeved on the screw of the bolt 4 to lock the backing plate 6 to the bottom of the sleeve groove 21, so that the rubber fender 2 is fastened to the ship outer plate 1. It effectively ensures the firmness and fit of the rubber fender during installation.

[0025] Optionally, the aluminum alloy ferrule 3 includes an annular welding portion 31 and a guide cover 32 covering one end of the welding portion 31. The guide cover 32 is provided with a bolt hole 321. The head of the bolt 4 is non-rotatably embedded in the welding portion 31, and the screw of the bolt 4 passes through the bolt hole 321. This arrangement not only facilitates welding, but also facilitates the installation and fixing of the bolt.

[0026] Optionally, the head of the bolt 4 is polygonal. A non-circular screw head is not easy to rotate and is more convenient during installation.

[0027] Optionally, the groove depth of the ferrule groove 21 along the first direction X is greater than the thickness of the aluminum alloy ferrule 3 along the first direction X. In this way, the aluminum alloy ferrule is not easily crushed when the rubber fender is tightened.

[0028] Optionally, the groove depth of the nut groove 23 along the first direction X is greater than the sum of the thicknesses of the nut 5 and the pad 6 along the first direction X. Such a nut groove can well place the nut and the pad, preventing the nut from damaging other ships or docks.

[0029] Optionally, the screw rod of the bolt 4 does not extend beyond the rubber fender 2. This prevents the bolt from damaging other ships or docks.

[0030] Optionally, the center lines of the ferrule groove 21, the screw through hole 22, and the nut groove 23 parallel to the first direction X coincide with each other. This arrangement facilitates the insertion of the bolt and can minimize the size of the slot.

[0031] Preferably, the screw hole 22 is opened at the center of the rubber fender 2. When it is set at the center of the fender, the overall force on the fender can be more balanced when it is fixed.

[0032] Optionally, the screw rod through hole 22 is a circular hole, and the diameter of the screw rod through hole 22 is larger than the outer diameter of the screw rod of the bolt 4. This arrangement facilitates the installation of the rubber fender.

[0033] Optionally, the backing plate 6 is made of stainless steel. Stainless steel has high hardness, is economical and practical, and is not easy to rust.

[0034] The installation method of the fender connection structure of the present invention is as follows:

[0035] During installation and connection, first embed the head of the bolt 4 in the aluminum alloy sleeve 3, and pass the screw of the bolt 4 through one side of the aluminum alloy sleeve 3, then weld and fix the aluminum alloy sleeve 3 to the position where it needs to be installed on the ship's outer plate 1, then put the rubber fender 2 on the screw of the bolt 4, and when the rubber fender 2 is close to the ship's outer plate 1, put the pad 6 on the screw of the bolt 4, and finally put the nut 5 on the screw of the bolt 4 to lock the pad 6 to the bottom of the sleeve groove 21, thereby fastening the rubber fender 2 to the ship's outer plate 1.

[0036] The fender connection structure for aluminum alloy ships provided by the utility model has not only high structural strength but also low maintenance cost and convenient installation.

[0037] The present invention has been described with reference to the above embodiments. However, these embodiments are merely exemplary embodiments of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and improvements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
