DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a barge-equipped ship, and more particularly to a barge fender structure.

[0002]

2. Description of the Related Art A barge-equipped ship has barge-loading girders (hereinafter referred to as "sponsons") provided on both sides of a stern so as to protrude. It is designed to carry cargo directly from the surface of the sea.
That is, at the time of loading the barge, the barge is pulled down to below the sponges by the winch provided on the hull, lifted by a gantry crane, and mounted on the ship. At the time of barge unloading, the barge is lowered by a gantry crane onto the lower sea surface between the sponsons and towed by a tug boat.

[0003] At the time of this barge loading, the barge is the hull and
In some cases, it may come into contact with additional objects (the rudder, the propulsion device) and damage them. In order to prevent such contact and damage accidents, the stern draft is equipped with a barge fender. However, the barge fender corresponds to a barge floating on the sea surface, and its equipment position extends to a submerged portion of the hull in order to cope with changes in draft of the hull and the barge.

[0004] For this reason, in a barge-equipped ship fixedly equipped with a barge fender, there is an inconvenience that the water flow around the hull is disturbed in the vicinity of the barge fender during navigation, and the propulsion performance of the hull is significantly reduced. In addition, in order to fix the barge fender, the stern shape of the conventional barge-equipped ship is such that the stern is submerged from the waterline as shown in FIG. 7, so that the propulsion performance of the hull is significantly impaired. There was an inconvenience.

[0005]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned disadvantages of the conventional type. In the present invention, the hull propulsion performance is ensured in an optimal state during navigation, and the hull is secured at berthing (during cargo handling). The aim of the present invention is to obtain a barge-equipped ship equipped with barge fenders which can protect the hull and appendages from damage caused by barge contact.

[0006]

[MEANS FOR SOLVING THE PROBLEMS] In a barge-equipped ship,
The stern is vertically movable, and is provided with a barge fender that is stored above the waterline when the ship is fully loaded at the time of navigation, and the lower part is submerged when loading and unloading. When the fender is moved down, a stopper is provided which comes into contact with the back surface of the barge fender and regulates the movement of the barge fender toward the hull at a predetermined position. Further, the barge fender is pivotally mounted on a position higher than the waterline at the time of full loading so as to be rotatable, and the barge fender is rotated by a cylinder to move up and down.

Further, a barge fender is hung on an elevating frame to be vertically movable, and a guide is fixed at a position higher than a waterline at full load, the elevating frame is moved along the guide, and the barge fender is moved by the elevating frame. I made it slide up and down. Further, the barge fender is suspended by a cylinder mounted at a position higher than the waterline at full load, and is provided so as to be movable up and down, and the barge fender is slid by the cylinder so as to move up and down.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic view showing an entire barge-mounted ship according to the present invention, FIG. 2 is a side view of a barge fender according to the present invention, and FIG. 3 is a front view thereof. FIG. 4 is a side view of another barge fender according to the present invention, and FIG. 5 is a front view of the same. FIG. 6 is a diagram showing the stern shape of a barge-mounted ship according to the present invention, and FIG. 7 is a diagram showing the stern shape of a conventional barge-mounted ship.

Reference numeral 1 denotes a hull of a barge-equipped ship, and reference numeral 2 denotes a sponson provided to protrude from the stern of the hull 1. The sponges 2 are provided on both sides in the hull width direction, and the barge 3 is loaded and unloaded between the sponges 2. 4 is the hull 1
It is a gantry crane for barge loading mounted on the upper part, and is movable to a position above the sponson 2. A barge fender 5 has a rubber block 6 attached to the surface thereof, and is rotatably mounted on a bracket 7 fixed to the stern part.

Reference numeral 9 denotes a cylinder, the cylinder part being pinned to the stern part 10 and the rod being a barge fender 5.
A pin 12 is attached to a lever 11 fixed to the lever 11. Accordingly, the barge fender 5 rotates and moves up and down by the expansion and contraction operation of the cylinder 9.

Reference numeral 13 denotes a stopper fixed to the stern, which contacts the back surface of the barge fender 5 to move the barge fender 5 to the hull side at a predetermined position, for example, as shown in FIGS. Regulation at a position perpendicular to. The stopper 13 is mounted at a position higher than the waterline when the load is full.

A plurality of barge fenders 5 are provided in the width direction within the space between the two sponges 2 provided at the stern, and an appropriate number may be used in common to share the cylinder 9. it can. In the example shown in FIG. 3, six barge fenders 5 are provided, and two barge fenders 5 are set as a set and connected to three cylinders 9.

4 and 5, reference numeral 14 denotes a lifting frame, 15 denotes a winch attached to the hull 1, 16 denotes a sheave provided on a stern deck, and 17 denotes a lifting frame 1.
4 and wound on a sheave 16 to winch 1
5 is a wire rope wound around. In addition, 18
Is a guide formed of a mold steel or the like and fixed to the stern at a position higher than the waterline at full load.
Of the guide 1 are fitted.
8 is moved up and down.

Reference numeral 5 denotes a barge fender, which is equipped with five barge fenders 5 in this example, is pinned 19 on the elevating frame 14, and is suspended. Therefore, when the winch 15 is operated to move the lifting frame 14 up and down, the barge fender 5 also slides and moves up and down.

The configuration of the present invention is as described above, and the operation will be described next. First, in the configuration shown in FIGS. 2 and 3, the barge fender 5 can be turned up and down by the operation of the cylinder 9. 4 and 5, the winch 15 can be operated to move the lifting frame 14 up and down, and the barge fender 5 can be slid up and down.

Therefore, at the time of barge loading, the barge fender 5 is first moved downward. At this time, the upper part of the barge fender 5 protrudes from the hull waterline, but the lower part is submerged. The back surface is in a state of contacting the stopper 13.

In this state, the barge 3 to be loaded is pulled into the sea surface between the sponsons 2 by a winch (not shown) provided on the hull 1, lifted by a gantry crane 4 and loaded on the hull 1. In pulling in barge 3,
The barge 3 contacts the barge fender 5 but does not contact the hull and appendages and does not damage them. Of course, the same applies when unloading the loaded barge 3.

When the barge 3 is mounted and the ship is sailing, the barge fender 5 is moved upward, and the barge fender 5 is stored at a position completely above the waterline. If the boat is sailed in this state, there is no submerged portion and the barge fender 5 does not become a resistance for ship propulsion. The same effect can be obtained by directly hanging the barge fender 5 on a cylinder attached to the stern and moving the barge fender up and down by the stroke of the cylinder.

[0019]

According to the present invention, the barge fender is made movable up and down, and the barge fender is used by moving the barge fender downward only during cargo handling, and the barge fender is moved up and retracted during navigation. Can be prevented from being damaged by contact with the ship's hull and accessories, and the ship's propulsion performance during navigation is not reduced.

In particular, in order to equip the barge fender, it is not necessary to consider the stern shape, and as a result, as shown in FIG. You can now.
