つてしまう欠点がある。 The amount of high-pressure water used is approximately 1.7/min when six nozzles are operated. Therefore, although the amount of water used is not that large, if you use it for a long time, the amount of water used will increase over time, and there is a drawback that your feet will become soaked with water.
特に例えば鉄道車両の塗装を剥離する場合には
被施工体の形状が大形であるため剥離作業に時間
が掛る。このため足元に落ちる水の量も増加し、
作業の邪魔になる欠点がある。 Particularly when removing paint from a railroad vehicle, for example, the object to be coated is large in size, so the removal work takes time. As a result, the amount of water falling at your feet also increases.
There are drawbacks that can hinder your work.

and a rubber-like elastic part 6c attached so as to protrude toward the workpiece 4 from the tip of the cylindrical part 6b. For example, three casters 7 are attached to the outer periphery of the cylindrical portion 6b. In this example, a ball bearing type caster is used. By providing the caster 7, the nozzle 1 can be freely moved along the surface of the workpiece 4 while keeping the distance L between the workpiece 4 and the nozzle 1 constant. I have to.

よい工具を提供できる。 As described above, according to this invention, the water ejected from the nozzle 1 is collected, so that the feet will not become soaked with water. Therefore, even if work such as removing paint from a large workpiece such as a railway vehicle is performed for a long time, the working environment will not be deteriorated. Further, since the peeled paint film can be collected together with water in the collection tank 9, the surrounding area will not be contaminated. This makes it possible to provide tools that are easy to use.

程増加させないで済むため作業性がよい。 Since the caster is attached to the cover, the nozzle can be easily moved along the surface to be processed, and the distance between the nozzle and the surface to be processed is maintained constant, so the water beam incident on the surface to be processed can be reduced. The pressure is almost constant, ensuring reliable machining, and the distance between the elastic part and the workpiece surface is always constant.
Water can be recovered efficiently, and suction means with small capacity can be used. Moreover, since the elastic pad is attached, even if there are small protrusions on the surface to be processed, the work can be carried out smoothly without being hindered by them. Since it has a structure in which a single cover is attached and the air inside is sucked, the structure can be made simple and compact, and the weight does not need to increase so much, resulting in good workability.
