Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a pusher barge type carrier.

[Conventional technology]

Conventionally used centerline hinge type fully open type carriers as shown in the side view of FIG. 1A, the plan view of FIG.

(1) When dumping cargo, the pushing joint opens left and right, so the structural members above the center of rotation (hinge) tilt inward, putting pressure on the necks of the pushing boats and risking damage. .

(2) Furthermore, when the cargo dumping is finished, the bodies of the transport vessels are wide open, so if a part of the bows of each barge gets stuck in this gap, this protruding bow gets in the way when the vessel is closed.

Therefore, in order to solve such problems,
As shown in the plan view of Figure 2A and the cross-sectional views of B and C in Figure 2, a structure in which the block is separate from the two-part structure has been proposed, but such a structure is complicated and cannot be fully opened. The merit of the formula is halved.

[Problem that the invention seeks to solve]

The present invention has been proposed in view of the above circumstances, and an object of the present invention is to provide a pusher barge type carrier having a pusher coupling part that is simple in structure and low in cost.

[Means for solving problems]

To this end, the present invention provides a structure in which the left and right hulls are divided into two on a vertical plane passing through the centerline, and are pivotally connected to each other on the vertical plane through a plurality of hinges, so that the bottom can be opened between the left and right hulls. In a pusher barge type carrier ship, which is configured to push a vertically split-bottom open type carrier vessel with a vertically split open cargo hold, a push barge type carrier ship is configured to push a vertically split open type carrier vessel with a vertically split open type cargo hold, and a push barge type carrier vessel is provided with a vertically displaceable vessel at the stern of at least one of the left and right hulls, and whose outer end is displaceable in the longitudinal direction. The present invention is characterized by comprising a substantially vertical abutting member that abuts against the bow of the pushboat, and a drive means that is provided at the stern and moves the abutting member slightly rearward.

[Effect]

With such a configuration, it is possible to obtain a pusher barge type carrier having a push-and-float coupling part that is simple in structure and low in cost.

〔Example〕

An embodiment of the present invention will be explained with reference to the drawings.
Figure 3A is a side view of the ship, Figure B is a plan view of Figure A, Figures 4A and B are partial perspective views showing the pushing joint in Figure 3, and Figure A is a closed view of the hold. Figure B shows the open state. Figure 5 is a side view of the carrier ship shown in Figure 3A during cargo dumping, Figure 6A is a partially enlarged view of Figure 5, Figure B is a plan view of Figure A, and Figure 7 is 6B is a partial plan view showing a modification of FIG. 6B; FIG.

First, in Figures 3 to 6, B indicates a push boat P at the stern.
This is a pusher barge-type carrier ship consisting of a port side hull BP and a starboard side hull BS, which have a vertical recess into which the bow part of the ship fits, and which are opened and closed by hinges 4, 4 on the longitudinal vertical plane including the centerline.

1 is a positioning rod whose lower end is pivoted to the lower end of the vertical recess at the stern of the port side hull BP and can rotate slightly around the lower end within the longitudinal vertical plane; 2 is a positioning rod on the upper deck of the hull BS. 3 is a hydraulic cylinder for rotating the positioning rod 1;
4 is the hinge for opening and closing the hull, 5 is the hinge for rotating the positioning rod, 6 is the fender of the pushboat P, which indicates its position when loaded, and 7 is the fender of the pushboat P, which makes it easier to move the pushboat relatively because the water of the carrier boat becomes lighter when dumping. Indicates the position where the side is lowered.

Reference numerals 8 and 9 indicate auxiliary devices such as bollard mooring lines for lateral positioning of the carrier and pusher when opening and closing, respectively; 10 indicates the hull facing the positioning rod 1;
The positioning rod support devices protrude from the top and bottom of the BS, and transmit the load applied to the rods to the transport vessel when the BS is pushed to sea after the opening/closing operation.

Reference numeral 11 denotes a gap fender, which is temporarily inserted from the side of the pushboat P or the carrier boat B to prevent contact between the sides of the carrier boat B and the pushboat P when the hull is opened and closed.

In such pushya barge type carriers,
When the hold is closed, as shown in Figure 4A,
The positioning rod 1 is stored in the hull BP in a vertical position, and when the hold is open, the positioning rod 1 assumes a position slightly tilted backwards, as shown in Figure B.

Therefore, during the dumping of cargo, the positioning rod 1
As shown by the broken line in Figure 5, the pusher is tilted slightly backwards, creating a slight clearance between the pusher P and the carrier B, so by using a positioning rod, the pusher can be positioned relatively to the rear of the carrier. let me,
The hull of the carrier can be opened and closed without losing the connection between the two.

In addition, the positioning rod can cooperate with mooring ropes, fenders, etc. to facilitate the maneuverability of the carrier ship in the fore and aft, as well as in the left and right directions.

Incidentally, the positioning rod can also be applied to a carrier ship having a flat stern, as shown at 1' and 1' in FIG.

〔Effect of the invention〕

In short, according to the present invention, the left hull and the right hull are divided into two on a vertical plane passing through the center line, and are pivotally connected to each other on the vertical vertical plane via a plurality of hinges, so that the bottom can be seen between the left and right hulls. In a pusher barge type transport ship in which a longitudinally split bottom open transport ship having an openable cargo hold is pushed by a pusher barge, an outer end is provided at the stern of at least one of the left and right hulls so as to be displaceable in the longitudinal direction. A vertically split pusher barge type with a simple structure, which is equipped with a substantially vertical abutting member that abuts against the pusher head of the barge, and a drive means provided at the stern section that moves the abutting member slightly rearward. The present invention is industrially extremely useful because it provides an open-bottom carrier.
