Fender device and ship equipped with the device {FENDER APPARATUS AND VESSEL HAVING THE SAME APPARATUS}

The present invention relates to a ship provided with a hull protection device and the device, and more particularly, to a ship having a fender device that can be used for parallel mooring and a device having the device.

In general, the fender is used to prevent the damage of the hull shell between the two ships in the case of a ship capable of parallel mooring between the ships.

As shown in FIGS. 1A and 1B, the fender 1 according to the prior art is coupled to a fender-only davit 3 in the upper deck 4 of the port or starboard of the vessel 2. It is used in the form of a fender assembly 10.

The plurality of fender combinations 10 of the prior art are arranged while maintaining a pre-designed interval along the fore and aft direction at the upper deck 4 of the port or starboard of the ship 2, thereby ensuring interference problems or passages with other equipment There is a problem that causes problems.

That is, the conventional davit (3) used in the fender assembly 10 is a pillar structure and a winch bent at a right angle to the end for pulling up an anchor, lifting a boat up or down, or pulling up or down a fender (1) Since it is provided, it is very difficult to secure the installation space of the davit (3) and the associated structure in the upper deck 4 of the port or starboard of the ship (2), there is a disadvantage that people can not pass.

That is, the fender assembly 10 is formed of a heavy structure such as a columnar structure and a winch, so there is a relatively high material consumption loss and difficult operation.

In the embodiment of the present invention can be installed in a narrow installation space of the upper deck of the ship by providing a fender portion operated by a foldable retractor portion, there is little material loss as a light structure and easy to operate the fender device can be provided have.

In an embodiment of the present invention, the fender is further stabilized by providing a plurality of hull extensions which are spaced at equal intervals along the bow and rear direction of the ship to avoid operating interference of the retractor and protrude in the width direction of the ship from the upper part of the hull outer wall. The vessel can be provided with a fender device that can be supported and stored so as to avoid operating interference between the retractor portion and the hull.

According to one aspect of the invention, a plurality of retractor portion having a joint frame is installed on the port or starboard upper deck of the ship and is deployed or returned in a fold, and a fender portion rotatably coupled to the free end of the articulated frame It may be a fender device that includes.

According to another aspect of the invention, the articulated frame may be formed of a bilateral coupling structure or a cantilever coupling structure.

According to another aspect of the invention, a vessel with a fender device may be provided.

Here, the ship may be spaced apart at regular intervals along the fore and aft direction of the ship and may protrude in the width direction of the ship from the upper hull outer wall to form a plurality of hull extensions to stably support the fender of the fender device.

Fender device according to an embodiment of the present invention provides a fender portion coupled to the foldable retractor portion can be installed in a narrow installation space on the upper deck of the ship, less material loss as a light structure, easy to operate, user passage It can make it easy to secure.

The fender device according to the embodiment of the present invention is configured such that a roller-type fender or a caterpillar-type fender, which is a fender part, is rotated at a free end of the retractor part, and the damper part is provided in the retractor part, so that the ship's transverse direction (for example, Loads or shocks may be dampened in response to ship-to-ship movement or agitation in the hull width direction) or in the longitudinal direction (eg bow direction).

The first actuator 112 and the second actuator 113 may have a cylinder body in which the hydraulic supply and recovery is made, and an operating arm reciprocating in such a cylinder body, and may have different operating capacities and sizes depending on the purpose of use. Can have

For example, the first actuator 112 is a main power cylinder that provides the articulated frames 115 and 116 with a force that is deployed or returned in a foldable manner. The first actuator 112 may be designed and manufactured with a relatively long stroke distance of the operating arm. In addition, the second actuator 113 is a sub-power cylinder for generating a force capable of lifting or lowering the first actuator 112 in response to the deployment or return, and may be designed and manufactured with a relatively short stroke distance of the operating arm. have.

The first actuator 112 or the second actuator 113 may perform an expansion operation or a contraction operation. Here, the extended operation may mean that the operating arm protrudes outward from the cylinder body within the predetermined stroke range to generate a pushing force while increasing the overall length of the actuator. In addition, the contraction operation means that the operating arm enters the inside of the cylinder body within a predetermined stroke to generate a pulling force while reducing the overall length of the actuator.

This first actuator 112 or second actuator 113 may form a conventional hinge or pivot connection for hinge or pivot coupling to its cylinder body or actuating arm.

The other ends of the free ends 117 and 117a may be coupled to both sides of the first fender part 120 to form a bilateral coupling structure.

That is, the first fender part 120 may be disposed between the free ends 117 and 117a of the articulated frames 116 and 116a, but the rotation shaft 121 is rotatably coupled to the free ends 117 and 117a. And a cylindrical roller-type fender 122 that couples the rotary shaft 121 to the center of the first fender part 120 and is formed of a fender material.

The roller-type fender 122 may be formed of a fender-proof material having excellent durability, abrasion resistance, oil resistance, fatigue resistance, and creep resistance, and may be soft (corresponding to the purpose of use or the arrangement position of the first body portion 100). The soft or hard material may be selected and used to exhibit a cushioning operation for each layer to maximize the shock absorbing performance.

For example, the roller-type fender 122 is laminated to surround the hard material layer 122a on the top of the rotary shaft 121, and is laminated to surround the soft material layer 122b on the top of the hard material layer 122a. Can be.
