The installation portion 14 of the inertial movement means 3 is a direction away from the edge 02 where the surfaces 01 of the two steel product structural plates intersecting about 90 degrees, that is, the direction of movement of the device, As shown in Fig. 4, the compressed air of the vibrator cylinder case 31 is used along the upper left inclination direction in which the device moves both in the upward direction away from the corner portion 02 and the left direction in the movement direction of the device. By using the inertial force generated when reciprocating, the inertial moving means 3 moving along the edge portion 02 of the device is fixed by the piston rod 32.

The attachment pipe 15 of the negative pressure adjusting means 4 is fixed to the cylindrical valve plate storage case 41.

The inside of the valve plate storage case 41 has a rod 44 on which a valve plate 43 is fixed at an end thereof to the boss 42 so that the original valve plate 43 enters and exits in the direction of the attachment pipe 15. The spring mount 45 is fixed to the other end of the rod 44 by a nut 46 made of a plurality of screws, and a compression coil is provided between the valve plate storage case 41 and the spring mount 45. The spring 47 is attached.

Next, the operation of the apparatus as described above will be summarized.

With the addition of the negative pressure generating means (not shown), the fluid in the reduced pressure region is extracted outside along the suction hose (not shown), whereby the reduced pressure region in use is reduced in pressure as necessary.

When the decompression region in use is depressurized, the pressure of the fluid acting on the decompression vessel 1 according to the fluid pressure difference in and out of the decompression region causes the decompression vessel 1 to face the surface 01 and the edge portion 02 of the steel product structural plate. ) Is pressurized, i.e. adsorbed.

In the adsorption state, if the vibrator cylinder case 31 is reciprocated in a direction away from the edge portion 02 and in the movement direction of the device, the device is formed by the inertia force of the vibrator cylinder case 31. Move according to 02).

In addition, in the adsorption and moving state, when the combustion material is injected at high speed toward the surface 01 of the steel product structural plate rather than the blast nozzle 61 together with the compressed air, the impact of the combustion material collides, such as rust or composition film Foreign object is removed.

After the injection, the combustion material is extracted to the outside along the suction hose (not shown) together with the atmosphere in the reduced pressure region by the action of the negative pressure generating means (not shown). Since the injection of the combustion material is carried out into the decompression region, dust generated during the collision of the combustion material or the combustion material is not scattered out of the decompression region.

The action of the negative pressure adjusting means 4 is as follows.

In the case where there is no negative pressure adjusting means 4, when compressed air is not injected from the blast nozzle 61, since the negative pressure in the reduced pressure region increases, the adsorption force of the device increases, which makes the movement of the device difficult.

In the case where the negative pressure adjusting means 4 is present, the negative pressure in the depressurized region is to be increased as in the case where the compressed air is not injected from the blast nozzle 61, but the fluid surrounding the apparatus is increased due to the pressure increase in the portion. Is larger than the force of the compression coil spring 47 to open the valve plate 43 in the direction of the tube 15 so that the fluid surrounding the apparatus flows into the negative pressure adjusting means 4 along the hole 48. Therefore, since the increase of the negative pressure is prevented, the adsorption force of the apparatus is kept constant, and the movement of the apparatus becomes easy.

As mentioned above, although the apparatus which concerns on 1st Example was demonstrated, the apparatus described below is attached to the apparatus of 1st Example.

5 to 9, the object to be subjected to the surface treatment is a T-shaped cross-sectional shape in which two surfaces intersecting the weld joints, that is, the corner portions 02, between the steel product structural plates. It is coming true.

In FIG. 5 or 8, a part of the adsorption | suction seal 2 protrudes to the surface of the other direction of the two surface which crossed, and the pressure reduction area | region is not formed. That is, an end portion parallel to the corner portion 02 is formed on the two intersecting surfaces, and a part of the adsorption seal 2 protrudes from the end portion, so that a reduced pressure region is not formed.

Accordingly, the problem that the cover plate 81 for covering the end portion and the opened portion surrounded by the adsorption seal 2 is mounted on the pressure reduction container 1 is eliminated, and at the same time, the steel product structural plate Even the cut end surface of the edge part of the surface 01 can enable surface treatment.

For this reason, since the part which contacted the U-shaped clearance gap among the cut sections of a steel product structural board will be exposed in the inside of a negative pressure space, the surface treatment of the cut section is also attained.

In addition, the sealing plate 83 can be made from wear-resistant materials, such as chromium, molybdenum, and cast iron.

Moreover, since there exist various dimensions with respect to the plate | board thickness of the surface 01 of a steel product structural board, the plate | board thickness of the cover plate 81 also changes to the plate | board thickness of the surface 01 of a steel product structural board. What is necessary is to prepare the thing of the thickness of a branch.

Next, the operation of the apparatus as described above will be summarized.

When the negative pressure generating means (not shown) is added, the fluid in the area surrounded by the surface 01 of the steel product structural plate, the pressure-reducing vessel 1, the adsorption seal 2, and the cover plate 81 is removed from the suction hose (not shown). Extracted outside and decompression area in use is depressurized as necessary.

When the decompression zone is depressurized during use, the pressure of the fluid acting on the decompression vessel 1 according to the fluid pressure difference in and out of the decompression zone causes the decompression vessel 1 to face the surface 01 and the edge portion 02 of the steel product structural plate. Absorb by applying pressure).

Moreover, in the said adsorption | suction state, if the vibrator cylinder case 31 reciprocates in the movement direction of the said apparatus which is a direction away from the edge part 02, the apparatus will be covered by the action of the inertia force of the cylinder case 31. It moves along the edge part 02 with the seal plate 83 by (81).

In addition, in the adsorption and moving state, when the combustion material is injected at high speed toward the surface 01 of the steel product structural plate rather than the blast nozzle 61 together with the compressed air, the combustion material collides, such as rust or composition film Foreign object is removed.

After the injection, the combustion material is extracted to the outside along the suction hose (not shown) together with the atmosphere in the reduced pressure region by the action of the negative pressure generating means (not shown).

Since the injection of the combustion material is injected in the decompression region, dust generated during the collision of the combustion material or the combustion material does not scatter out of the decompression region.
