い。Generally, in the early stages of rusting on a ship's hull, small areas of rust are scattered, and only the rusted areas are removed without damaging the healthy parts of the rusted coating. Ideally, the area should be repaired and then repainted. By the way, the conventional centrifugal projection type grit blasting rust removal equipment for ship hull shells is equipped with only one centrifugal projection head with a cleaning width of around IM; cannot be changed arbitrarily.

に説明する。Therefore, when rusted parts are scattered on the hull outer plate, it is not possible to selectively polish only the small area of rusted parts. Also,
As another device, sandblasting is actually used,
The drawback is that a large amount of dust and abrasive materials are scattered. This invention takes the above points into consideration, and by arranging a plurality of small centrifugal projection heads with narrow widths in parallel, and remotely controlling the supply and stop of the grinding material to each head individually, At the same time, it is capable of selectively polishing and cleaning rust on partially rusted parts such as the hull outer plate, using the cleaning width formed by one centrifugal projection head as a unit. Next, the present invention will be described in detail with reference to the drawings showing one embodiment thereof.

により遠隔制御する。On the other hand, each centrifugal projection head 6 is continuously rotating, and by feeding the abrasive material into the head 6, the abrasive material projected from each head 6 is spread out in a fan shape as shown in A in FIG. The rust can be removed by colliding with the outer panel 16 in a vertically linear pattern along the trajectory. Then, only while each head 6 passes over the rusted part B, the abrasive material is applied to the required head 6.
``Open the required solenoid valve 13 and open the jet pipe 1.''
Compressed air is ejected from 2, and the abrasive material is supplied from the abrasive material receiving pipe 10 to the head 6 by air flow conveyance. In addition, the solenoid valve 13 is closed in the head 6 in the part where the rusted part B is not present.
No abrasive material is supplied to that rod 6. The operation of each electromagnetic valve 13 is remotely controlled by visual inspection by a worker 30 on the auto shifter 24.

することにより、選択的に研掃除錆できる。Incidentally, since each head 6 is covered with a head cover 14, it is not possible to directly check the positional relationship between the rusted part B and the head 6 with the naked eye, but the position where the head 6 passes and the rusted part are determined by the drill guide 27. Check the position of part B and operate the required switch of the solenoid valve 13. In this case, after operating the switch of the solenoid valve 13 at the position where the polishing guide 27 has passed, the opening and closing of the solenoid valve 13 is delayed until the head 6 actually moves to the position where the polishing guide 27 has passed. It is necessary to do so. Therefore, a delay timer is built into the electric circuit of the switch of the solenoid valve 13, and the distance between the polishing guide 27 and the head 6 is changed by the time the head 6 moves.
After the operation, the solenoid valve 13 is operated with a delay.
That is, although the operator 30 operates the electromagnetic valve 13 after confirming the rusted part B at the position of the polisher's guide 27, the rusted part B can be accurately polished. As described above, according to the rust removal device of this invention, a plurality of centrifugal projections are arranged continuously in the vertical direction and project the polishing material in the vertical direction to form a polishing pattern having a width in the vertical direction. a head, a main abrasive material supply pipe through which abrasive material flows down from an abrasive material supply tank, a plurality of abrasive material supply branch pipes branched from the main pipe, and abrasive material from each of the branch pipes. A plurality of receiving pipes for the cutting material temporarily stop the flow of the material, and jets of compressed air from the material branched from the compressed air pipe and flowing down to the respective receiving pipes are used to direct each of the centrifugal projection heads. By providing a plurality of compressed air jet pipes for feeding and a plurality of solenoid valves that are installed in each of the jet pipes and are opened and closed individually by remote control, it is possible to carry out continuous cleaning. By stopping the supply of abrasive material to the centrifugal projection head 6 at the corresponding position, parts that do not require polishing and cleaning can be selectively cleaned.
