Abstract

PROBLEM TO BE SOLVED: To easily and surely switch a split barge from a box barge, and vice versa for a barge which is served for both the split barge and the box barge. SOLUTION: In a barge which is served for both a split barge and a box barge in which bottom blocks of triangular section are arranged in a mud hold so that the mud hold bottom is inclined in the split barge mode, and the bottom blocks are replaced to set the mud hold bottom to be horizontal in the split barge capable of directly dumping earth and sand in the hold into the sea by opening right and left hull bodies connected by a pair of hinges separated from each other in the forward and aft part of a hull, the common use of the split barge and the box barge is realized by turning a forward end part of the long side 1a across the right angle of the bottom block 1 of triangular section by 180 deg. as the rotary part, and the rotary part of the bottom block 1 comprises two hinges 2 and 3, a link 4 to connect these two hinges to each other, and a stopper 5 provided on a lower part of the link 4 to stop the turn of the link 4 during the rotation.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a split barge and a box barge.

[0002]

2. Description of the Related Art Both a split barge and a box barge are earth transport vessels that carry dredged soil and land surplus soil.
There are features as shown in (1) and (2). (1) by opening the split barge (see FIG. 3) hull b ₁ and b ₂ of the left and right that are connected by a pair of front and rear hinges a right and left, the soil was to be dumped in the sea sediment in Dorokura c directly It is a ship and usually has a shape as shown in FIG. In order to dump the soil smoothly, as shown in Fig. 3 (b), the inclination of the bottom of the mud at the time of dumping needs to be about 50 °, but the opening angle of the hull can only be about 30 ° due to its mechanism. (It usually opens and closes with a hydraulic cylinder, but if it opens more than 30 degrees, the stroke of the hydraulic cylinder becomes too long, which causes problems in mechanism and strength.)
A slope of about 0 ° is used to ensure a 50 ° inclination of the mud when dumping. Lifting machines (grabs,
Although soil can be lifted by a bucket, etc., since the bottom of the mud crate has an inclination, the efficiency of the lifting work is poor, and
Remains at the bottom.

(2) Box barge (refer to FIG. 4) The hull is of an integral type, and the earth and sand in the mud crate c 'is excavated by earth excavation equipment such as grabs and buckets provided on the quay or the excavation ship. It is a ship. In this type of earth transport ship, the bottom of the mud cell c 'is horizontal in order to efficiently excavate with the earth unloading machine (FIG. 4 (b)).

Heretofore, there has been a barge which can be used as a split barge and a box barge. However, as shown in FIG. 5, in the split barge, the mud bottom is inclined at the time of split and the mud bottom is horizontal at the time of the box, so that the block d (ship) has a triangular cross section as shown in FIG. Divided into several parts in the length direction). When switching from split to box or vice versa, move this block d to the opposite side as indicated by the arrow in FIG.
And keep the bottom horizontal.

[0005] Disadvantages of this conventional method are that (1) it is necessary to firmly fix it to the bottom of the mud by welding or bolts so that the block d does not slip off during splitting, and (2) the blocks are arranged in a box. In this case, a large amount of earth and sand will enter the space e formed on the center line of the hull, so a blocking plate will be required. This must also be fixed by welding, bolts, etc. (3) Since the blocks are swapped left and right In addition, heavy machinery requires a long reach, and the block must be completely lifted, so that a large lifting capacity is required.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a split barge / box barge dual-purpose ship that can easily and reliably switch between split / box. More specifically, a) no welding work or the like is required at the time of split / box switching, and no heavy-duty heavy machine work is required; b) the split time device is stable; c) the box When used as a barge, it is an object of the present invention to prevent projections that may interfere with the earth-lifting machine from being put out of the mud store, and to provide a possible combined use ship.

[0007]

By opening the hull b ₁ and b ₂ of the left and right that are connected by a pair of hinges that spaced towards the front and rear of the hull SUMMARY OF THE INVENTION As it can be dumped into the sea directly sediment in the hold In the split barges, a split barge and a box barge, in which triangular cross-section bottom blocks are arranged in the mud, so that the mud bottom is inclined at the time of split barge and replaced at the time of box barge to make the mud bottom horizontal. Bottom block 1 with a triangular cross section
The tip of the longer side (1a) sandwiching the right angle of
By rotating by 80 °, the split barge and the box barge can be used together, and the rotating portion of the bottom block 1 is rotated by the two hinges 2 and 3 and the link 4 connecting the two hinges and the rotation of the link 4 during rotation. And a stopper 5 provided below the link 4 for stopping the vehicle. Except for the hinge portion, the portion adjacent to the hinge portion extends the ship bottom block 1 so that no gap is generated between the hinge portion and the steel plate 7 constituting the mud bottom.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. The tip of the longer side 1a sandwiching the right angle of the ship bottom block 1 having a right-angled triangular cross section was attached to the mud bottom through hinges 2, hinges 3 and links 4 connecting these. In addition, as shown in FIG.
When the box barge is formed as shown in FIG. 2, the hinge portion projects upward as shown by reference numeral 8 ′ when the box barge is formed, so that the combination of the two hinges 2, 3 and the link 4 is used to avoid this protrusion. Mechanism. Then, the link 4 is arranged so as to have an inclination of about 45 ° when the split barge is formed. By making the link 4 inclined, it is possible to prevent the bottom block 1 from sliding down when the barge is split. A link stopper 5 is arranged below the hinges 2 and 3. The portions other than the hinge portion are extended to the position indicated by reference numeral 6 so that there is no gap in the steel plate 7 constituting the mud bottom when the box barge is formed as shown in FIG. 1C.

With the above configuration, the ship bottom block 1 can be moved as follows. (1) The lifting point is set, for example, at the position of 0 (FIG. 1A). (2) When lifting is started, first, the ship bottom block 1 rotates upward to the position of X in FIG. 1D around the lower hinge 3, so that the link 4 is horizontal and hits the link stopper 5. (3) When it is further lifted and rotated, the upper hinge 2
, The bottom block 1 rotates. (4) When the center of gravity of the bottom block 1 moves toward the center line of the hull from the hinge 2, the bottom block 1 rotates to the position of Y in FIG. It faces horizontally. (5) Next, invert the other bottom block in the same manner, open the minimum required angle in the state of FIG. 3 (b) so as not to interfere at the center, install the bottom block, close the bottom again, Complete box barge.

[0010]

According to the first aspect of the present invention, no work is required to fix the bottom block 1 to the hull by welding or bolts during split barge. Therefore, there is no need to release the bottom block fixing device at the time of switching. 2) Switching from box barge to split barge is the same. 3) During the box barge, since the hinges 2 and 3 and the link 4 are all stored below the bottom of the mud, there is no upward protrusion on the bottom of the mud, so that a smooth lifting operation can be performed. 4) When switching, one end of the bottom block 1 is hinged 2 and 3
And since it is connected to the hull via the link 4, the switching operation can be performed safely even at sea.
