Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a fully open centerline hinge type ship used for earth transport ships, stone transport ships, dumping ships, etc.

[Conventional technology]

Figures 12 to 15 show a fully open centerline hinge type ship equipped with a conventional pushing device; Figure 12 is a plan view thereof, Figure 13 is a side view thereof, and Figure 14 is a figure 13. Fig. 15 is a sectional view taken in the direction of - arrow, and Fig. 15 is a rear front view thereof.

A fully open centerline hinge type ship equipped with a conventional pushing device is generally configured as shown in Figs. Hinge device 1 equipped on
The stern section of the hull, which is pushed by a barge, is also opened left and right along its entire length by means of a hydraulic cylinder 2.

For this reason, they have the following drawbacks, and in general, it is not possible to connect them with efficient pushboats, and in the past, means of pulling and navigating using a tugboat or means equipped with a propulsion device have often been adopted.

(A) When opening the hull, the lower part of the pushing device 3 is opened left and right like the hull, but the upper part higher than the hinge device 1 is tilted inward, so the pushing device 3 is opened to the left and right. If the installation interval is narrow or if the part on the deck is high, the ends of the port and starboard pushing devices 3 will hit each other and be damaged. Therefore, there are restrictions on the size, shape, and mounting position of the pushing device 3, and the pushing boats that can be used are also limited.

(b) When the hull is opened, the bow of the pushboat digs into the opening in the hull, making it impossible to close the hull.

(c) In order to prevent the above (b) and to facilitate the opening and closing of the hull, it is necessary to separate the bow of the pushboat from the fully open centerline hinge type ship during the opening and closing process. The type vessel becomes unable to maneuver, and cannot be maneuvered to the exact dumping position or maintained at the dumping position.

(d) Dumping work cannot be carried out until the work of separating the pushboat in (c) above is completed, and pushing cannot be carried out until the fully open centerline hinge type ship is completely closed.
Operational efficiency is poor.

In order to eliminate the above drawbacks, the 16th
As shown in Figures 1 to 18, a ship in which a connecting block Sa separate from the hull S is connected has been developed.

[Problem that the invention attempts to solve]

However, if such a conventional means of providing a connecting block Sa is used, both the hull S and the connecting block Sa will have a very large and complicated structure, and the number of hinges between them will also increase. Therefore, the advantage of the centerline hinge type full opening method, which is a simple structure, is halved and the manufacturing cost increases.In addition, the buoyancy of the connecting block Sa does not change when the hull is opened, so the There is also the problem that only the end of the hull on the bow side sinks, causing the hull to list while the stern draft on the existing side is maintained.

The present invention aims to solve these problems, and uses a simple mechanism that can be formed at a low cost to enable efficient connection with a pushboat while maintaining safety when the hull is opened. The object of the present invention is to provide a hinge type ship with a relatively rotating pusher receiving plate.

[Means for solving problems]

For this reason, the hinge type ship with a relatively rotatable push boat receiving plate of the present invention is designed to connect the left hull and right hull of the hinge type ship so that they can rotate relative to each other in a fully open centerline hinge type ship. A hinge device is provided on the center line of the hull, and a guide platform having a circular arc surface centered on the rotation axis of the hinge device is fixed to the stern ends of the left and right hulls, respectively. At the same time, a pushboat receiving plate is provided approximately parallel to the cross section of the hinged boat, and a pushboat receiving plate is provided with a pair of left and right rollers on the front surface that engage with the arcuate surfaces of these guide stands, respectively. It is characterized in that it is connected to the above-mentioned left hull or right hull through a guide stand and rollers so as to be relatively rotatable.

[Operation] With the above configuration, the fully open centerline hinge type boat is connected to various pushboats via pushboat receiving plates.

Further, when the hull is opened, the hull is maintained in a stable attitude without causing vertical heeling.

First, a first embodiment of the present invention will be described. It is configured as shown in FIGS. 1 to 9, and has a left hull 10a and a right hull 10b that constitute a hinge type ship 10 of a fully open centerline hinge type ship. are connected to each other so as to be relatively rotatable by a hinge device 1 disposed on the hull centerline CL of the hinge type ship 10. Further, receiving plate support guide stands 15, 15 are fixedly installed at the stern ends of the left hull 10a and the right hull 10b, respectively. The receiving plate support guide stand 15 is connected to the hinge device 1
It has a circular arc surface 15a centered on the pin, and is shaped as shown in FIGS. 5 to 9 so that there is no support when opening and closing the hull 10.

Moreover, a push boat receiving plate 1 engages with the tip of the push boat 11 that pushes the hinged boat 10 and receives the pushing thrust.
3 are disposed substantially parallel to the cross section of the hinge type boat 10, and two rollers on the left and right sides are pivotally attached to the front surface of the boat receiving plate 13 using pins 17, respectively. These rollers 16 are engaged with the circular arc surface 15a of the support plate support guide base 15, and the pusher support plate 13 is connected to the left hull 10a and the right hull 1.
It is designed to be able to rotate relative to 0b.

Further, in order to prevent the roller 16 from accidentally coming off the circular arc surface 15a of the receiving plate support guide stand 15, a receiving plate stopper 18 is fixedly provided on the circular arc surface 15a.

Further, the pushboat cradle 14 is attached to the pushboat support plate 13 with bolts, and the mounting position of the pushboat cradle 14 can be adjusted from side to side to suit the shape of the stern (tip) of the pushboat 11. There is.

The push boat cradle 14 is adapted to engage with the stern portion of the push boat 11 to prevent the hinge type boat 10 from shifting from side to side.

Since the hinge type ship with relatively rotating push boat receiving plate as the first embodiment of the present invention is constructed as described above, when pushing the hinge type boat 10, the push boat 11
The front end surface of the pushboat receiving plate 13 is engaged with the rear end surface of the pushboat receiving plate 13, and the pushboat receiving plate 14 is adjusted so as to fit the bow shape of the pushboat 11.
