Description

[Detailed Description of the Invention] This invention relates to a device for introducing and retrieving explosives, etc. in oceanographic research vessels and the like.

For example, when conducting a geological survey of the seabed, it is necessary to continuously detonate explosions at predetermined locations in the sea, so a chain with explosives and buoys that hold the explosives at a certain depth are attached at regular intervals is placed in the sea. The work of loading and unloading onboard ships is frequently carried out. In addition, control cables and compressed air supply hoses are connected to explosives.
In conventional ships, chain loading and lifting work is performed on the upper deck using rollers installed on the upper deck, which requires a large work space on the upper deck and can damage cables and hoses. Explosives may be difficult to load and retrieve, making it difficult and inefficient.

This invention was made in view of the above-mentioned circumstances, and the object is to provide a device that can easily and efficiently carry out loading and retrieving of explosives and the like.

This invention will be explained below with reference to drawings showing embodiments.

In Figures 1 and 2, both sides 2 of a ship 1 are shown.
Above the upper deck 3 near the
Each rail 5 has an I-shaped cross section extending to the rear of the ship, and the end of each rail 5 in the center of the ship is slightly bent inward. Winches 6 are provided on the upper deck 3 below each rail 5 in the center of the ship. A table 8 is provided on the upper deck 3 below the rail 5 at the stern end, as shown in detail in FIG. 3, and is rotated by a hydraulic cylinder 7. A lifting rail 9 having an I-shaped cross section similar to 5 is provided. As shown in detail in FIG. 4, an inverted U-shaped lifting frame 11 is fixed to the upper surface of the upper flange 10 of the lifting rail 9. It is suspended through. Furthermore, elongated holes 15 are provided on both sides of the web 14 at both ends of the elevating rail 9. Inside the elevating frame 11, there is an inverted U-shaped elevating body 16.
is provided, and the elevating body 16 is connected to the elevating frame 11 via an elevating cylinder 17 that penetrates the upper surface of the elevating frame 11.
It is suspended from a support 18 fixed to the top surface.
Bifurcated shutters 19 are formed at both ends of the elevating body 16, and each shutter 19 is fitted into a hole 15 of the elevating rail 9 so as to be vertically movable. In addition, a rotatable guide plate 20 is provided at the stern end 4.
is provided. There are multiple trolleys 2 on the rail 5.
1 is attached to the trolley 21, and a hook 22 is suspended from the trolley 21.

A plurality of fittings 24 are fixed to the chain 23 at regular intervals, and an explosion gun (container) 25 is always attached to the fittings 24 except during maintenance and inspection. Further, a control cable and a compressed air supply hose 26 are connected to the explosion gun 25.

On board the ship, the chain 23 is suspended from the hook 22 of the trolley 21 by the attachment 24, and when not in use, is stored suspended from the rail curved portion 5a in the center of the ship.

The operation of charging the explosive gun 25 is carried out as follows.

That is, first, the guide plate 20 at the stern end 4 is
It is fixed in an oblique position as shown by solid lines in the figure and FIG. Then, as shown by solid lines in FIGS. 3 and 4, the shutter 19 is raised to open both ends of the elevating rail 9, and the elevating rail 9
is raised to match the rail 5, and with the table 8 fixed in a horizontal position as shown by the solid line in FIG. It is stopped on the lifting rail 9. Next, the shutter 19 is lowered to close both ends of the lifting rail 9, and then the lifting rail 9 is lowered to lower the explosion gun 25, fixture 24, and chain 23 onto the table 8. Next, the hook 22 of the trolley 21 is removed from the fixture 24 lowered onto the table 8, the lifting rail 9 is raised, the shutter 19 is raised, both ends of the lifting rail 9 are opened, and the trolley 21 is moved to the rail. 5 and temporarily store it. Meanwhile, at the same time as the hook 22 is removed from the fixture 24 of the chain 23 on the table 8, the buoy 27 is attached to the fixture 24.
Attach the wire rope 28 and rotate the table 8 downward. As a result, the explosive gun 25 falls into the sea along the table 8 and the guide plate 20. By repeating the above operations, Explosive Gun 2
5 are dropped into the sea one after another, and the explosive guns 25 are held at constant intervals and at a constant depth by a chain 23 and a buoy 27. The wire rope 29 of the winch 6 is connected to one end of the chain 23, and the explosive gun 2 is
5 can be dropped.

The work of retrieving the explosive gun 25 is carried out as follows.

That is, first, the guide plate 20 at the stern end is fixed in a vertical position as shown by chain lines in FIGS. 1 and 3. Then, the trolley 21 stored at the rear end of the rail 5 is moved onto the elevating rail 9, both ends of the elevating rail 9 are closed by the shutter 19, and the table 8 is moved as shown by the chain line in FIG. The chain 23 is pulled by the wire rope 29 using the winch 6, and the explosion gun 25 is pulled up from the stern end 4 onto the table 8. Explosive gun 25 is on table 8
Once the table 8 is placed on the top, rotate the table 8 to the horizontal position, lift the explosion gun 25, fixture 24 and chain 23 slightly, remove the buoy 27 from the fixture 24, and attach the hook 22 of the trolley 21 to the fixture 24. Attach to. Next, the elevating rail 9 is raised to suspend the explosion gun 25 from the trolley 25, and both ends of the elevating rail 9 are opened to move this trolley 21 and the explosive gun 25 forward, and then the next trolley 2
1 from the rear end of the rail 5 onto the elevating rail 9. At the same time, the table 8 is rotated diagonally downward and the next explosive gun 25 is pulled up. By repeating the above operations, the explosive guns 25 dropped into the sea are pulled up onto the ship one after another.

In the above embodiment, the explosion gun 25 is used as the explosive, and compressed air is supplied to the explosion gun 25.
Although an explosion of compressed air is caused within the chain, explosives such as gunpowder may be loaded each time into a container attached to the chain. Even in this case, gunpowder or the like can be easily loaded while the container is suspended. Rail 5, table 8,
The configurations of the elevating rail 9, trolley 21, etc. are not limited to those of the above embodiment, and can be modified as appropriate. For example, the rear end of the rail 5 may be folded onto the ship when not in use. It is also possible to lower the explosive gun 25 and the like directly onto the upper deck 3 without providing the table 8. Furthermore, the guide plate 20 at the stern end 4 is not absolutely necessary.

As described above, the device according to this invention
A rail 5 is provided above the upper deck 3 near the ship and extends from the center of the hull to the rear of the stern end 4, and a container 25 for explosives, etc., which runs along the rail 5 and is attached to a chain 23, is attached and detached. A trolley 21 that can be hung freely, and trolleys 21 and 2
An elevating rail 9 is provided on a part of the rail 5 so that it can be raised and lowered in order to lower the container 25 and chain 23 suspended from the stern end onto the upper deck 3 or onto the table 8 provided on the upper deck 3. Since the trolley 21 is equipped with a chain 23 and the like, it is possible to carry out loading and retrieval operations of explosives and the like while the chain 23 and the like are suspended from the trolley 21. Therefore, there is no need to secure a large working space on the upper deck 3, the loading and unloading operations are easy, and there is no risk of damaging cables, hoses, etc. connected to explosives, etc.
Further, by using the elevating rail 9, it is possible to easily attach and detach explosives and the like to and from the trolley 21. Furthermore, since the chain 23, explosives, etc. can be stored at any location while suspended from the trolley 21, there is no need to secure a particular storage space, and maintenance and inspection are also easy.
