Abstract

PURPOSE:To launch a ship easily and without any concern about the overturn thereof by supplying a fluid like the air into each bag body of many bag type jacks under pressure for keeping a ship afloat from a launching way. CONSTITUTION:A launching way 1 is provided so as to have downward slope in a launching direction and a ship 2 is placed thereon. In addition, a slip way 3 having approximately similar slope is laid under the ship 2. Many bag type jacks 8 having a contractible body at the outside of an elastic bag body are laid between the upper surface of the slip way 3 and the ship 2 via a lubricant. Then, a fluid is supplied to the bag type jacks 8 under pressure to keep the ship 2 afloat from the launching way 1, and the ship 2 is made to slide on the slip way 3, together with the jacks 8, thereby being launched. According to this construction, the ship 2 is launched simply by supplying a fluid like the air to the jacks 8 under pressure. Thus, the ship 2 can be easily and safely launched.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ship launching method and device used for launching a new ship or a repair ship.

[0002]

2. Description of the Related Art Conventionally, when launching a ship as described above,
Usually, it is performed as shown in FIG. 41 in the figure
Is a pedestal and has an inclination that makes the launch direction lower.
And the ship 42 is mounted on it. Reference numeral 43 is a support base composed of a wedge 44. When launching, the wedges 44 are hit from the outside to remove them one by one to deepen the slope and launch.

[0003]

However, in the above launching method, it is difficult to remove the wedge 44, and therefore, the releasing method is often incorrect, and the vessel 42 falls to the side. Therefore it is also dangerous.

The present invention has been made to solve the above problems, and its object is to provide a method and apparatus for launching a ship that is easy and does not cause the ship to tip over, and thus is not dangerous. is there.

[0005]

With respect to the present invention for achieving the above object, first, a method will be described in which a ship 2 is placed on a pedestal 1 which is inclined at a low launching direction, and the ship 2 Of a bag jack 8 having an elastic body 7 on the outer side of a bag body 6 made of an elastic body with a lubricant 5 interposed between the upper surface 4 of the slide table 3 and the ship 2 below. A large number of them are positioned, and a fluid is press-fitted into the bag jack 8 to float the ship 2 from the pedestal 1 and slide on the slide 3 together with the bag jack 8 for launching. This is the method of launching a ship.

As for the apparatus, the pedestal 1 inclined at a low launching direction; the slide 3 provided with an inclination substantially the same as the pedestal 1; the lubricant 5 combined with the slide 3; A plurality of bag jacks 8 each having an elastic body 7 provided outside an elastic bag 6; a fluid pressure supply device 11 for supplying a fluid to the bag jacks 8 under pressure; It is a launching device for a ship.

[0007]

When launching the ship 2 placed on the cradle 1 as described above, a fluid such as air is press-fitted into each bag body 6 of the plurality of bag body jacks 8. The ship 2 is levitated on the pedestal 1 by. Then, the boat 2 slides on the slide 3 together with the bag jack 8 by the lubricant 5, and thus launches. In this case, the bag jack 8 also enters the sea or the like together with the ship 2. However, the bag jack 8 is pulled and collected by previously providing a string or a wire.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 to 3, reference numeral 1 designates a pedestal, which is provided with an inclination such that the launching direction is lowered, and a vessel 2 is placed on the pedestal 1. And the same ship 2
A slide 3 having substantially the same inclination is provided below the slide. Next, 8 is a bag jack arranged in large numbers on the slide 3, and as an example, a sealed bag made of an elastic body made of a material as shown in FIG. In FIG. 4, 13 is a synthetic rubber.

The synthetic rubber 13 is, for example, a neoprene layer, 14 is a synthetic fiber layer, and 15 is a linen layer. On the outside of the bag body 6, a pantograph made of stainless steel is provided as a stretchable body 7. Reference numeral 8 is a bag jack formed in this way, and is communicated with a pressure supply device 11 for a fluid such as air or water. Reference numeral 17 is a communication pipe, 18 is a valve, 19 is a safety valve, and 20 is a cutler. The bag jack 8 is placed on the slide 3 via a lubricant using silicon oil as an example, and the boat 2 is positioned on the bag jack 8.

Reference numeral 21 is a base, and 22 is a support. Reference numeral 23 is a wheel, which is adapted to rotate on a rail (not shown). Since the operation of this embodiment is substantially the same as the operation of the present invention described above, the description thereof will be omitted.

Since the present invention is constructed as described above, when the vessel 2 is launched, it is sufficient to press the fluid into the bag jack 8 so that the vessel 2 can be easily launched. Unlike the conventional method of removing the wedge, it is not dangerous, and it is possible to prevent the vessel from falling due to a failure in removing the wedge.
