The state which connected the pusher ship to the rear part of a barge ship is shown, (a) is a side view, (b) is a top view. It is an enlarged side view of the stern vicinity of the barge ship of Fig.4 (a). It is an enlarged plan view of the stern vicinity of the barge ship of FIG.4 (b). It is a side surface enlarged view which shows the connection structure in the state where the storage part of the barge ship became empty. FIG. 5 is an enlarged plan view of the vicinity of the stern of a barge with the rear of the pusher boat tilted to the port side with respect to the barge.

Hereinafter, an embodiment of a connection structure and a connection method between a floating structure and a pusher ship 1 according to the present invention and a steering method of the floating structure will be described in detail with reference to the drawings. In the following description, the case where the barge ship 14 as a ship is pushed by the pusher ship 1 will be described as an example.
FIG. 1 shows a pusher ship 1 according to the present embodiment, wherein (a) is a side view and (b) is a plan view. In addition, in FIG.1 (b), only the external shape of the pusher ship 1 is shown.
As shown in the figure, a pusher ship 1 according to this embodiment includes a ship body 2, a screw 4 as a propulsion mechanism provided at the lower rear of the ship body 2, and a steering mechanism provided at the rear of the screw 4. And a control room 8 provided on the deck of the ship main body 2.

  The ship body 2 is formed in a semicircular shape with a predetermined radius at the front part, is formed to have the same width from the front part to the rear end part, and the left and right corners at the rear are chamfered. Buffer materials 12A and 12B made of, for example, rubber or foamed resin are attached to the outer peripheral surface of the ship body 2. As shown in FIG. 1, a cushioning material 12 </ b> A is attached to the front portion of the ship body 2 so as to extend in the horizontal direction along the arc-shaped outer peripheral surface. The buffer material 12B is attached so that it may extend in the up-down direction at intervals in the horizontal direction. Further, on both sides of the rear portion of the ship body 2, wire fixing columns 10A and 10B for fixing the wires are provided upright.

  The screw 4 is rotationally driven by an engine (not shown) disposed in the ship main body 2 and applies a propulsive force toward the front to the pusher ship 1. The engine that rotates the screw 4 can control the driving / stopping and the rotation speed when an operator operates a control device provided in the operation chamber 8. As an engine for rotating the screw 4, it is desirable to use an engine having a sufficient driving force so that the barge ship 14 can be pushed while the pusher ship 1 is connected to the barge ship 14.

  The rudder plate 6 is fixed to a rotating shaft 6a extending downward from the rear portion of the ship body 2 so as to extend rearward. The rudder plate 6 can be rotated left and right around the rotation shaft 6a by the control device, and thereby the traveling direction of the pusher ship 1 can be steered.

  2A and 2B show a barge ship 14 to be pushed by the present embodiment, where FIG. 2A is a side view and FIG. 2B is a plan view. FIG. 3 is an enlarged view of the vicinity of the stern in FIG. As shown in these drawings, the barge ship 14 includes a ship body 16, a storage part 17 formed on the ship body 16 so as to extend in the front-rear direction, and a wire operation part 20 provided at the rear part of the ship.

The shape from the front end portion to the middle portion of the ship body 16 is the same as the shape of the known barge ship 14, and both sides of the rear end portion are chamfered in an arc shape. Further, in the center of the rear end portion of the barge ship 14, a concave portion 18 having a substantially triangular shape in plan view having the same cross-sectional shape is formed from the bottom of the ship to the upper end portion of the stern. The concave portion 18 is formed in an arc shape centered on a point where the inner edge of the innermost portion 18A is located on the central axis of the ship body 16, and has a width toward the rear continuously from the innermost portion 18A. It has a C-shaped shape that spreads out. The radius of the arc shape of the innermost portion 18A of the recess 18 is formed to be equal to the distance from the arc center of the tip portion 2A of the pusher ship 1 to the outer edge portion. In this embodiment, the outer edge portion of the tip portion 2A of the pusher ship 1 refers to the outer peripheral surface of the cushioning material 12A, and the distance from the arc center to the outer edge portion of the tip portion 2A of the pusher ship 1 is a semicircular radius. It is equal to the length obtained by adding the thickness of the cushioning material 12A.
The storage unit 17 is a rectangular parallelepiped space defined in the ship body 16 and stores coal or the like.

  The wire operation unit 20 includes a pair of wire winding mechanisms 22A and 22B, and the wire winding mechanisms 22A and 22B can wind and send the wires 24A and 24B independently. In the present embodiment, the bow-side wire winding mechanism 22B can wind and send out the wire 24B extending to the starboard side of the hull, and the stern-side wire winding mechanism 22A winds and extends the wire 24A extending to the port side of the hull. It can be sent out. Supports 26 </ b> A and 26 </ b> B are erected at positions corresponding to the sides of the pair of wire winding mechanisms 22 </ b> A and 22 </ b> B at the edge of the hull 2. Guide hooks 28A and 28B are provided on both sides of the rear end of the outer periphery of the hull 2, respectively. Wires 24A and 24B extending from the pair of wire winding mechanisms 24A and 24B toward the hull side are extended toward one end side, changed in direction by the columns 26A and 26B, and guided by the guide hooks 28A and 28B. It extends rearward along the outer peripheral surface of the hull 2.

  As will be described later, the wire operation unit 20 of the barge ship 14 can be connected to the control device of the operation room 8 of the pusher ship 1 via wireless or wired operation, and operates the control device of the operation room 8 of the pusher ship 1. Thereby, each wire winding mechanism 22A, 22B can be made to wind up and send out a wire.

Hereinafter, a method of connecting the pusher ship 1 to the rear part of the barge ship 14 will be described.
FIG. 4 shows a state in which the pusher ship 1 is connected to the rear part of the barge ship 14, (a) is a side view, and (b) is a plan view. FIGS. 5 and 6 are an enlarged side view and a plan view of the vicinity of the stern of the barge ship 14 in FIGS. 4 (a) and 4 (b), respectively. As shown in these drawings, when the pusher ship 1 is connected to the rear part of the barge ship 14, first, the pusher ship 1 is located at the center extending in the front-rear direction of the pusher ship 1 and the barge ship 14 at the rear of the barge ship 14. The shafts (hereinafter simply referred to as central axes) are arranged so as to coincide with each other, and the pusher ship 1 is advanced toward the barge ship 14. Then, when the cushioning material 12A of the distal end portion 2A of the pusher ship 1 comes into close contact with the innermost portion 18A of the recess 18 formed in the rear part of the barge ship 14, the pusher ship 1 is stopped.

  Next, the front ends of the pair of wires 24A and 24B extending from the pair of wire winding mechanisms 22A and 22B of the barge ship 14 are fixed to the wire fixing columns 10A and 10B provided at the rear end of the pusher ship 1, respectively. To do. Then, the wire winding mechanisms 22A and 22B are operated by the control device of the operation chamber 8 of the barge ship 14 to wind up the pair of wires 24A and 24B until there is no sag. Thus, the pair of wires 24A and 24B connect the support posts 26A and 26B on both sides of the concave portion 18 of the barge ship 14 and the rear portions of the pusher ships 10A and 10B.

  In this way, the pusher ship 1 has the front end 2A in contact with the innermost part 18A of the recess 18 of the barge ship 14 and the both ends of the rear end are pulled toward the barge 14 by the pair of wires. Thus, the front end 2A of the barge ship 14 can be connected to the rear end of the pusher ship 1.

  FIGS. 4A and 5 show a connection structure in a state where the storage unit 17 of the barge ship 14 is fully loaded with coal. On the other hand, FIG. 7 is an enlarged side view showing the connection structure in a state where the storage unit 17 of the barge ship 14 is empty. The recess 18 of the barge ship 14 has the same cross-sectional shape from the bottom of the ship to the upper end of the berth. Therefore, regardless of the loading amount of the barge ship 14, the front end 2 </ b> A of the pusher ship 1 becomes the recess 18 of the barge ship 14. It can be made to contact.

  According to such a connecting structure of the barge ship 14 and the pusher ship 1, the arcuate radius of the innermost part 18 </ b> A of the recess 18 is set to the semicircular radius of the tip part 2 </ b> A of the pusher ship 1. Since it is formed equal to the length plus the thickness, the relative angle of the pusher ship 1 with respect to the barge ship 14 (angle between the central axes) can be changed. Hereinafter, as an example, as shown in FIG. 5, from the state where the barge ship 14 and the pusher ship 1 are arranged in a straight line, the rear portion of the pusher ship 1 is ported with respect to the barge ship 14 as shown in FIG. 8. A case of changing to a state inclined to the side will be described.

  First, the wire winding mechanism 22A corresponding to the port-side wire 24A of the barge ship 14 winds up the wire 24A connected to the port side rear portion of the pusher ship 1, and the wire winding mechanism 22B corresponding to the starboard-side wire 24B sags. The wire 24B connected to the starboard rear portion of the pusher ship 1 is sent out while keeping the pressure from being generated. Thereby, the port side of the rear end part of the pusher ship 1 is pulled toward the side via the wire 24A. Since the tip portion 2A of the pusher ship 1 is formed to be equal to the semicircular radius of the tip portion 2A plus the thickness of the cushioning material 12A, the tip portion 2A contacts the innermost portion 18A of the recess 18 of the barge ship 14. In a contact state, the tip portion 2A can smoothly rotate around the semicircular central axis, and the rear portion of the pusher ship 1 can be tilted to the port side with respect to the barge ship 14.

  Further, when the rear part of the pusher ship 1 is inclined to the starboard side with respect to the barge ship 14, the pusher ship 1 is connected to the starboard rear part of the pusher ship 1 by the wire winding mechanism 22 </ b> B corresponding to the starboard side wire 24 </ b> B. The wire 24B is wound up, and the wire 24A connected to the rear port side of the pusher ship 1 may be sent out so that no slack is generated by the wire winding mechanism 22A corresponding to the wire 24A on the port side.

  Thus, according to the connection structure of the barge ship 14 and the pusher ship 1 of this embodiment, the pusher ship 1 can be directed (tilted) in a desired direction with respect to the barge ship 14. At this time, the wires 24A and 24B come into contact with both sides of the rear end portion of the ship body 16 of the barge ship 14. For this reason, it is preferable that both sides of the rear end portion of the ship body 16 of the barge ship 14 are chamfered in an arc shape.

Next, a method of pushing the pusher ship 1 by the barge ship 14 in a state where the pusher ship 1 is connected to the rear part of the barge ship 14 will be described.
In order to make the barge ship 14 go straight, first, the pair of wire hoisting mechanisms 22A and 22B are operated by the control device of the operation chamber 8 of the pusher ship 1, and as shown in FIG. The center axis of the pusher ship 1 is made to coincide. And a control apparatus is operated in the operation room 8 of the pusher ship 1, and while rotating the screw 4 of the pusher ship 1, the rudder board 6 is rotated to the position extended in the front-back direction. Thereby, the pusher ship 1 moves forward in the hull center axis direction, and the barge ship 14 is pushed forward by the pusher ship 1 and moves forward.

  Next, the case where the barge ship 14 is turned with a large turning radius will be described. When turning the barge ship 14 with a large turning radius, the central axis of the barge ship 14 and the central axis of the pusher ship 1 are made to coincide as shown in FIG. . In this state, the rudder plate 6 of the pusher ship 1 is tilted according to the turning direction by the control device, the screw 4 of the pusher ship 1 is rotated, and the pusher ship 1 is advanced. Since the pusher ship 1 is smaller than the barge ship 14, the turning force obtained by the rudder plate 6 of the pusher ship 1 cannot turn the barge ship 14 with a small turning radius. By tilting, the barge 14 can be turned.

  Next, the case where the barge ship 14 is turned with a small turning radius will be described. In the following description, a case where the traveling direction of the barge ship 14 is turned toward the port side will be described. When turning the barge ship 14 with a small turning radius in this way, the pair of wire hoisting devices are operated by the control device, and the rear part of the pusher ship 1 is moved relative to the barge ship 14 as shown in FIG. Tilt to the port side. In FIG. 8, the pusher ship 1 is rotated until the side surface of the recess 18 of the barge ship 14 and the side surface of the pusher ship 1 come into contact with each other, but the rotation angle of the pusher ship 1 is set to the turning angle of the barge ship 14. What is necessary is just to make it the angle according to. That is, it is not always necessary to rotate the pusher ship 1 until the side surface of the recess 18 of the barge ship 14 and the side surface of the pusher ship 1 abut.

  With the pusher ship 1 tilted with respect to the barge ship 14 as described above, the rudder plate 6 of the pusher ship 1 is set to a position extending in the front-rear direction, the screw 4 is rotated, and the pusher ship 1 is advanced in the central axis direction. As a result, a propulsive force is applied to the rear of the barge ship 14 in front of the pusher ship 1 (that is, in the starboard direction of the barge ship 14 in the state shown in FIG. 8), and the pusher ship 1 turns greatly (the state shown in FIG. 8). Then, you can make the front in the port direction). That is, the barge ship 14 can be turned using the pusher ship 1 instead of the rudder.

  Furthermore, when turning the barge ship 14 more greatly, the pusher ship 1 may be tilted in the horizontal direction with respect to the barge ship 14 and the rudder plate 6 of the pusher ship 1 may be rotated. For example, in the state shown in FIG. 8, the rudder plate 6 of the pusher ship 1 may be further tilted so that the rear part faces the port side so that the traveling direction of the pusher ship 1 is directed to the port side. Accordingly, a larger force acts on the rear part of the barge ship 14 in the lateral direction than when the rear part of the pusher ship 1 is tilted to the port side with respect to the barge ship 14. It becomes possible to turn with.

  In the above description, the case where the barge ship 14 is turned so that the traveling direction is toward the port side has been described. However, in the case where the barge ship 14 is turned so that the traveling direction is directed toward the starboard side, the above description is given. What is necessary is just to perform the work which carried out right and left.

As described above, according to the present embodiment, the concave portion 18 having a shape widening toward the rear is formed at the rear end portion of the barge ship 14, and the pusher ship is formed in the innermost portion 18 </ b> A of the concave portion 18. The wire is fixed to both sides of the concave portion 18 at the rear portion of the barge ship 14 and both sides of the rear portion of the pusher ship 1 by a pair of wires 24A and 24B extending from the pair of wire winding devices 22A and 22B in a state in which the front end portion 2A of the one is in contact. Since the columns 10 are connected to each other, the pusher ship 1 can be tilted with respect to the barge ship 14 by winding one wire by one wire winding device and sending the other wire by the other wire winding device. .
And according to this embodiment, since the pusher ship 1 can be inclined with respect to the barge ship 14 in this way, the barge ship 14 can be turned using the pusher ship 1 instead of a rudder. That is, when pushing the barge ship 14 by the pusher ship 1, if it turns slightly, it turns only with the rudder of the pusher ship 1, and if it makes a large turn, the pusher ship 1 is moved with respect to the barge ship 14. In the case of further turning, the pusher ship 1 can be turned by tilting the pusher ship 1 with respect to the barge ship 14 and further by tilting the rudder plate of the pusher ship 1. That is, according to the present embodiment, when pushing the barge 14 by the pusher ship 1, turning with a large turning radius and turning with a small turning radius can be easily handled.

  Moreover, in this embodiment, since the innermost part 18A of the recessed part 18 of the barge ship 14 is formed in circular arc shape, and the front-end | tip part 2A of the pusher ship 1 is formed in corresponding arc shape, By operating the wire hoisting devices 22A and 22B in a state where the outer edge portion of the distal end portion 2A is in contact with the innermost portion 18A of the concave portion 18 of the barge ship 14, the pusher ship 1 can be smoothly moved around the center of the arc. Can be rotated.

  Further, since the radius of the arc shape of the innermost portion 18A of the recess 18 of the barge ship 14 is equal to the distance from the center of the arc shape of the pusher ship 1 to the outer edge portion, the center of the arc shape of the tip portion 2A of the pusher ship 1 is obtained. The pusher ship 1 can be rotated with respect to the barge ship 14 in a state in which the center of the arc shape of the innermost part 18 </ b> A of the recess 18 of the barge ship 14 coincides. Further, the contact area between the tip of the pusher ship 1 and the innermost part 18A of the recess 18 of the barge ship 14 can be increased.

  Further, by tilting the pusher ship 1 with respect to the barge ship 14 and further tilting the rudder plate 6 of the pusher ship 1, the barge ship 14 can be turned with a smaller turning radius.

  In the present embodiment, the barge ship 14 is provided with the pair of wire winding mechanisms 22A and 22B, but the present invention is not limited thereto, and the pusher ship may be provided with a pair of wire winding mechanisms.

Further, in the present embodiment, the radius of the arc shape of the innermost portion 18A of the concave portion 18 of the barge ship 14 is equal to the distance from the arc center of the tip portion 2A of the pusher ship 1 to the outer edge portion. Although the recessed part 18 was formed, the shape of the recessed part 18 is not restricted to this. For example, an arc-shaped convex part may be formed at the innermost part of the concave part of the barge ship, and a concave part having the same radius as this convex part may be formed at the tip part of the pusher ship. However, as in the present embodiment and the above example, it is preferable that the innermost portion of the concave portion of the barge ship and the tip portion of the pusher ship are formed in a corresponding shape.
Further, the radius of the arc shape of the innermost portion 18A of the concave portion 18 of the barge ship 14 does not necessarily have to be equal to the distance from the arc center of the distal end portion 2A of the pusher ship 1 to the outer edge portion. The pusher ship can be smoothly rotated even if the distance from the arc center to the outer edge of the front end of the barge is smaller than the arc-shaped radius of the innermost part of the recess of the barge ship. However, if the radius of the arc shape of the innermost part of the recess of the barge is equal to the distance from the arc center of the tip of the pusher ship to the outer edge, the innermost part of the recess of the barge and the tip of the pusher ship Since the part which contacts with becomes large, a connection structure is stabilized.

  Further, in the present embodiment, the cushioning material 12A is attached to the outer periphery of the distal end portion 2A of the pusher ship 1. However, the present invention is not limited to this, and the cushioning material may be attached to the inner peripheral surface of the recess of the barge ship. In this case, it is preferable that the radius of the arc shape at the tip of the pusher ship is equal to the distance from the center of the arc shape at the innermost part of the recess of the barge ship to the inner peripheral surface of the cushioning material.

In the present embodiment, the tips of the wires 24A and 24B are fixed to the wire fixing columns 10A and 10B provided on both sides of the rear portion of the pusher ship 1, but the fixing position of the wires is not limited to this, and the pusher ship It suffices if it is behind the center of the semicircle at the tip of 1.
In the present embodiment, the wires 24A and 24B are routed along the outer peripheral surface of the rear of the barge ship 14, but the present invention is not limited to this. For example, the wire fixing strut of the pusher ship 1 straight from the struts 26A and 26B. You may run around so that it may extend to 10A, 10B.

  In the present embodiment, the case where the barge ship 14 is pushed by the pusher ship 1 is described. However, the present invention is not limited to this, and the case where a ship such as a container ship, a cargo ship, a general passenger ship is pushed by the pusher ship is also used. The present invention can be applied.
