DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a pusher barge.

[0002]

2. Description of the Related Art Conventionally, there is a pusher barge integrally connected with a pusher having a propulsion and steering function at a rear portion of a barge capable of loading a large amount of cargo or the like.

[0003]

However, despite the fact that the barge and the pusher are each formed in an appropriate boat shape with low resistance, no consideration is given to the shape of these connecting parts, and therefore, the resistance is low. Becomes extremely large, reducing the speed of navigation, increasing fuel efficiency,
The stormy weather navigation ability is low, so that stormy weather evasion may be required to make it impossible to operate at a fixed time, and there are problems such as a decrease in operational efficiency, and its use is limited.

[0004] In order to solve this problem, a straightener is provided on the port side of the stern of the pusher to streamline the connecting portion.
There is a problem that sufficient streamlining cannot be performed, the resistance decreases only slightly, and the resistance when the pusher alone travels alone increases extremely.

[0005] Further, there is a problem that the relative position between the barge and the pusher at the time of connection is slightly deviated, so that the above-mentioned underwater shape is deteriorated, and the above-mentioned problem is further worsened.

Further, when separating the barge and the pusher, with the conventional pusher barge, the separation between the barge and the pusher cannot be performed immediately immediately after the separation because the interval between the barge and the pusher is small. For example, the pusher and the barge swing separately, and the barge and the pusher repeatedly collide with each other, thereby damaging both hulls.

Further, conventionally, most of the transportation of cargo, earth and sand, etc., depends on land transportation by trucks or the like, which causes traffic congestion, problems of exhaust gas in the global environment, problems of energy resources, and the like. Therefore, it is conceivable to switch the transportation from the port facility closest to the starting point of the above-mentioned transportation to the port facility nearest to the ending point to marine transportation to solve the above-mentioned problems. Since there is a disadvantage in terms of cost due to the need for additional work such as transshipment, and the merits of marine transportation cannot be fully utilized, switching from land transportation to marine transportation as described above has not been carried out smoothly. is there.

[0008]

Therefore, in order to solve the above-mentioned problems, a pusher barge according to the first aspect of the present invention comprises a left hull and a right hull connected by a center hull, which are formed in a catamaran type. A pusher having a fitting space gradually expanding forward between the hull and the right hull, and a stern portion formed in an elongated substantially trapezoidal shape having a gradually decreasing rearward shape; A barge that can be inserted into the space, the stern of the barge is inserted into the fitting space of the pusher so that the pusher is externally fitted to the barge and connected, and the rear end of the stern of the pusher and the stern of the barge The rear end was located on substantially the same vertical plane.

According to a second aspect of the present invention, when the pusher and the barge are connected, the outer wall of the left hull and the outer wall of the right hull of the pusher are respectively arranged in the front-rear direction with the outer wall behind the hull of the barge. And when the pusher and the barge are connected to each other, the inner wall of the left hull and the inner wall of the right hull of the pusher are connected to the barge as described in claim 3. It is also characterized in that it is brought into close contact with the outer wall of the stern.

Further, as set forth in claim 4, a bridge is provided on an upper portion of the central hull, and a rudder is provided on each of the left hull and the right hull, and a propeller interlocked with an engine inside the hull is provided. Another feature is that the ladder and the engine can be operated from inside.

Further, in the pusher barge according to the fifth aspect, the rear ends of the left hull and the right hull arranged substantially in parallel with each other are connected to each other by a connecting portion to form a stern portion, so that they are substantially U-shaped in plan view. The inner space of the left hull and the right hull is tapered and formed into a tapered shape to form a mating space gradually expanding forward between the left hull and the right hull. A pusher, and a stern formed in an elongated substantially rectangular shape extending rearward and having a stern which can be fitted into the fitting space.The stern of the barge is fitted into the fitting space of the pusher. When the pusher was fitted over the barge and the pusher and the barge were connected, the resistance was reduced by setting the underwater shape of the connecting portion from the barge to the pusher to a streamlined shape.

Further, when the pusher and the barge are connected, the inner wall of the left hull and the inner wall of the right hull of the pusher are brought into close contact with the outer wall of the stern of the barge. There is also a feature in doing so.

According to a seventh aspect of the present invention, the barge is provided with a vehicle space where vehicles and the like can pass and park.
