Even when performing such a rust removing operation on a curved surface portion, the self-propelled vehicle 1 can easily travel by turning the entire rust removing machine 3 by operating the turning base 5 without turning. . In summary, according to the present invention, the boom, the turning base, the first turning member, the slide arm, the second turning member, and the third turning member are selectively operated. As a result, the position and posture of the rust removing brush can be changed in various ways, so that the rust removing brush can be applied not only to a vertical steel plate surface such as the ship side but also to a curved surface such as the bow and stern with an appropriate operating posture. The rust removal work can be performed efficiently by contact. Further, since the rust removal operation can be performed by remote control, the operation can be performed safely without the worker receiving dust such as rust generated at the time of rust removal. Also, a frame around the anti-rust brush
A rust-proof brush on the frame
That a pressing guide is attached to make contact with the surface with constant pressure
The rust-preventive brush against the wall at an appropriate pressure.
Rust prevention function is reduced due to insufficient contact pressure
Or, on the contrary, damage to the rust prevention brush due to excessive contact pressure, etc.
It can be prevented beforehand.
