Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention is made of glass fiber reinforced plastic (hereinafter, FR).
It is related to a catamaran used for dismantling a small abandoned ship (made by P).

[Conventional technology]

In general, many small fishing boats, leisure motor boats, yachts, and the like are made of FRP, and these have been put into practical use for several decades, and many have already reached the service life. However, because it has good corrosion resistance, which is a characteristic of FRP, it is left on the coast for a long period of time without being decomposed naturally like a wooden ship even if it becomes an abandoned ship, spoiling its aesthetic appearance and scattering glass fiber. Doing so may also be a source of waste pollution.

Therefore, it is necessary to artificially dismantle such a scrapped ship, but conventionally, an appropriate dismantling means for the scrapped ship has not been established.

[Problems to be solved by the invention]

As mentioned above, FRP small vessels are often left on the coast and need to be transported to land-based waste treatment facilities for post-treatment, but even small vessels are transported as they are. Is extremely difficult.

Also, when dismantling in an abandoned place, mechanical cutting with a cutting grindstone or cutting with ultrahigh pressure fluid is considered as a normal means, but both require manual operation and are attached to abandoned ships The scattering of the substance and the minute dispersion of the cutting waste on the glass fiber generated from the FRP itself are dangerous work for the operator who dismantles the cutting, and may also pollute the environment.

The present invention is intended to solve the above-mentioned problems, and a dismantling ship for dismantling a ship, which enables dismantling of a ship waste efficiently, safely, and without environmental pollution. The purpose is to provide a catamaran.

[Means for solving problems]

Therefore, the catamaran for dismantling abandoned vessels of the present invention is a catamaran composed of a port hull and a starboard hull, and provides a working space between the port hull and the starboard hull described above, and ascends and descends to the working space. A waste vessel holding device, a cutting device for cutting and dismantling the waste vessel held by the waste vessel holding device, and an isolation device for isolating the working space from external seawater. Is characterized by.

[Work]

In the above-mentioned catamaran for dismantling abandoned ships of the present invention, the dismantling work of the abandoned ship is performed using the working space between the port hull and the starboard hull of the catamaran, and at that time, the holding of the abandoned ship It is carried out by a waste ship holding device that can be raised and lowered. Then, when the abandoned ship is dismantled by the cutting device, the work space is isolated from the external space by the isolation device.

First, a first embodiment of the present invention will be described. As shown in FIG. 1, in a catamaran 100, a working space 4 covered with an upper hull 3 of a hull between a port hull 1 and a starboard hull 2. Is formed, and in this work space 4, FR
The P abandoned ship 5 is to be dismantled.

That is, there is provided a lattice-shaped processing table 7 as a waste ship holding device, which is supported by at least four struts 6 provided on the inside of the port side hull 1 and the starboard side hull 2 so as to be vertically movable via a support ring 7a, An articulated manipulator 8 having an ultra-high pressure water jet nozzle 9 as a cutting device is provided above the processing table 7.

Further, in the port side hull 1, an ultra high pressure water generator 10 for supplying ultra high pressure water to the ultra high pressure water injection nozzle 9 is installed, and various devices such as an articulated manipulator 8 and an ultra high pressure water generator 10 are also installed. A control device 11 including a computer for driving and controlling is installed.

Further, in order to isolate the work area 12 included in the work space 4 from the general area 13, the seat 14 and the seat 14 are separated.
There is provided a sheet-like isolating device including a guide rail 15 and the like that can deploy the sheet.

In addition, the purification device 1 for purifying seawater in the working area 12
6 and a drainage pump 17 are also equipped.

With the above-described configuration, when the dismantling work of the FRP abandoned ship is performed, first, as a preparatory step, as shown in FIG.
Work for guiding the abandoned ship 5 to the processing table 7 is performed.

That is, the ropes 23 and 24 are hung on the abandoned FRP waste ship 5 in front of the catamaran 100, and the winches 21 and 22 are operated to guide the waste ship 5 above the lattice-shaped processing table 7. In this case, the processing table 7 needs to be lowered to the lowest position of the column 6.

Next, as shown in FIG. 3, the processing table 7 is raised and fixed to the operating region of the ultra-high pressure water jet nozzle 9 mounted at the tip of the articulated manipulator 8.

Further, the working sea area 12 is isolated from the general sea area 13 by extending the sheet 14 wound around the supply roll 25 at the stern portion and winding the sheet 14 around the winding roll 26 at the bow portion. This is a structure that prevents unnecessary substances such as chips generated when the FRP waste ship 5 is cut with the ultra-high pressure water from leaking to the general sea area 13. FIG. 7 shows an example of an isolation device including the sheet 14 and the like.

After such a preparation step, in the next cutting step, the ultra high pressure water generator 10 is driven to inject the ultra high pressure water from the ultra high pressure water injection nozzle 9 at the tip of the multi-joint manipulator 8,
Work for cutting the FRP waste ship 5 is performed.

In this case, the ultra-high pressure water injection nozzle 9 is the FRP waste ship 5
Is controlled so as to move along the outer shape of the treatment table, and the treatment table 7 is not damaged by the residual energy of the treatment solution, so that the treatment chamber 7 is passed through the gap 7b of the lattice-shaped member. (See Fig. 6). The state after completion of the cutting step is as shown in FIG. 4, and in the subsequent post-processing step, the cut and dismantled waste ship 51 made of FRP is housed by the hoisting rope 27 in a hold (not shown). Has become.

Further, since the seawater in the working sea area 12 may contain chips of FRP, waste oil, etc., the purifying device 16 and the drainage pump 17 are operated to purify the seawater, and then the general sea area 1
Released to 3.

FIG. 5 shows a state in which the catamaran 100 for dismantling an abandoned ship moves in the sea area. The articulated manipulator 8 is housed in the upper structure 3, and the processing table 7 is located at the top of the support column 6. Since the sheet 14 is fixed, the sheet 14 is wound around a winding roll 26 so that the sheet 14 does not interfere with the movement of the sea area.

As a cutting device, instead of the super high pressure water jet nozzle 9,
A cutting tool such as a cutter or a grinder may be used, and in that case, a power supply unit is installed instead of the ultrahigh pressure water generator 10.

Moreover, you may make it use the nozzle 9 and the said cutting tool together.

Next, in the second embodiment of the present invention shown in FIGS. 8 to 10, instead of the sheet-shaped separating device including the sheet 14 in the first embodiment, as shown in FIG. A pool-shaped container 14 '(see FIG. 10) that can be moved up and down along the support 6 via a support ring 25' and a pool-shaped isolation device including a drive mechanism (not shown) are provided below. Is similar to that of the first embodiment.

Therefore, in the cutting process of the dismantling work of the abandoned ship 5, as shown in FIG. 9, the upper edge of the pool-shaped container 14 'is kept above the level of the external seawater, and the ultra-high pressure water injection nozzle is maintained. Unnecessary materials such as chips produced by the cutting operation by 9 are stored in the pool-shaped container 14 '.

The purification of seawater in the pool-shaped container 14 'is performed by the purification device 16 and the drainage pump 17.

Further, when the catamaran 100 for dismantling an abandoned ship moves in the sea area, the pool-shaped container 14 ′ is fixed to the upper part of the column 6 as well as the processing table 7.

Also in the case of the second embodiment, a cutting tool such as a cutter or a grinder may be used as the cutting device instead of the ultra-high pressure water injection nozzle 9. In that case, the ultra-high pressure water generator 10 is used.
The power supply is installed instead of.

Moreover, you may make it use the nozzle 9 and the said cutting tool together.

In each of the above-described first and second embodiments, a large number of columns supporting the waste ship 5 are erected on the lattice-shaped processing table 7 and the waste ship 5 is treated with ultra-high pressure water. When cutting, it is possible to sufficiently prevent the processing table 7 from being damaged by the ultra-high pressure water.

In particular, in the case of the first embodiment, by providing the support columns, the treatment table 7 can be submerged near the water surface, and thus the treatment table 7 can be more reliably prevented from being damaged by ultra-high pressure water due to the buffering action of seawater. Can be prevented.

Next, in the third embodiment of the present invention shown in FIGS.
Compared to the case of the first embodiment described above, instead of the sheet-shaped separating device including the sheet 14, as shown in FIG.
A pool-shaped container 14 '(see FIG. 13) that can be moved up and down along the support column 6 through a support ring 25' and a pool-shaped isolation device including a drive mechanism (not shown) are provided. Instead of the pool-shaped container 14 '
There is a metal fitting 15 'for dismantling a ship inside the ship (first
(See FIGS. 3 and 14), but the other structure is similar to that of the first embodiment.

The pool-shaped container 14 'is provided with a seawater inlet / outlet 18 with an opening / closing lid as shown in FIG.

With the above-described configuration, also in the case of the third embodiment, the dismantling work after the abandoned ship is performed in substantially the same manner as in the cases of the first and second embodiments. Then, as shown in FIG. 12, the FRP abandoned ship 51 that has been cut and dismantled is accommodated by the hoisting machine 27 in a hold (not shown).

Purification of seawater in the pool-shaped container 14 'is performed by the purification device 16 and the drainage pump 17.

〔The invention's effect〕

As described above in detail, according to the catamaran for dismantling abandoned ships of the present invention, dismantling equipment for abandoned ships made of FRP or the like is equipped on the catamaran, and therefore the abandoned ships left on the coasts of various places. Can be dismantled on the spot, which can significantly contribute to the purification of the beach.

Further, in the dismantling process, since the work is performed in the isolated work space and the cleaning process can be performed together, no harmful substance is released to the outside. Furthermore, the dismantling work can be performed by remote control, which can contribute to the safety of workers.
