Description

[0001] The present invention relates to an integrated tug-barge system,

The present invention relates to an integrated tug pants system including a barge and a tug line.

Pants systems which are adapted to load cargo and which are constructed to include propulsive pants and propulsive tugboats are known. Such pants systems often include one propulsion tug arranged for several pants. This structure is operated so that one pants is propelled from the sea while the other pants are loaded / unloaded from the port. This means that tugboats and crews with mechanical devices are effectively used in the seas, thereby producing less unproductive time at the port. Typically, such a pants structure is a pusher-pants combination, in which the tug is connected to the stern of the pants to push the forward of the barge forward. Examples of structures of known barges are disclosed, for example, in British Patent 2 132 566A and U.S. Patent 4,356,784.

Conventional pantographs are of the integrated tug-barge (ITB) type, where the tug lines and the barges are submerged in a mutually strong connection so as to form one unit, There is no movement.

However, in the integrated tug-barge (ITB) system, the frictional resistance phenomenon may occur due to the difference in linearity between the barge and the tugboat, and the draft of the tugboat is greater than the barge, The propeller of the tug boat may be exposed above the water surface.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an integrated tug pugging system capable of minimizing frictional resistance due to a linear difference between a barge and a tug.

It is another object of the present invention to provide an integrated tug-pants system in which a propeller of a tug attached to a barge can stably provide thrust.

The problems to be solved by the present invention are not limited to the above-mentioned problems. Other technical subjects not mentioned will be apparent to those skilled in the art from the description below.

According to an aspect of the present invention, there is provided a hull comprising: a first hull having a docking space; A second hull having a propulsion unit, which is inserted into the docking space and docked to the first hull; And a docking unit for fixing the second hull to the first hull; The docking space of the first hull may be provided in a wired form surrounding the bottom of the second hull and the second hull may be docked in the form of a forefoot in the docking space.

In addition, the propulsion device includes an engine having a power shaft extending inside the second hull and extending to the outside; A rotating shaft connected to the power shaft at one side and extending outside the bottom plate; And a propeller rotatably coupled to the rotary shaft; The height of the propeller can be varied by tilting the rotary shaft.

In addition, in the propulsion device, the power shaft and the rotary shaft may be connected by a universal joint for tilting the rotary shaft.

Further, the docking unit may include a socket member installed on one of the first hull and the second hull; And a locking member installed on the other of the first hull and the second hull, and coupled to the socket member.

The docking unit may further include a controller for releasing the locking of the locking member in an emergency.

In addition, the binding portion between the first hull and the second hull may further include a sliding damper for preventing vertical motion of the binarized longitudinal direction.

In addition, the second hull may further include a deckhouse capable of adjusting the height of the hull so as to easily secure a view.

The docking space may further include rollers for slidingly supporting the bottom of the second hull so that the docking operation of the second hull is smoothly performed on the floor.

According to the embodiment of the present invention, since the tugboat is docked on the barge with a stern trim, the shereline can be locked even at a small draft, thereby providing a stable propulsion force.

According to the embodiment of the present invention, when the propeller is exposed on the sea surface after the tugboat is docked to the barge line, the height of the propeller is changed by tilting the rotary shaft, so that the propeller is locked below the sea surface.

According to the embodiment of the present invention, the height of the deckhouse of the tugboat is raised to have a remarkable effect of solving the problem of blindness due to cargoes on the barge.
