2. Description of the Related Art When welding reinforcing bones to structural materials such as bridges and structural steel plates for ships, black skin, rust, weld beads and scale, and a primer (for the purpose of preventing rust on structural materials) If there is a surface deposit such as the first coating which has been previously treated in 1.), there is a problem that blow holes are generated in the welded joint portion and the quality of welding is deteriorated.

Therefore, conventionally, the above-mentioned surface deposits have been polished and removed in advance.

FIGS. 5 and 6 show an example of a conventional polishing apparatus, which is a drive drum d driven by a motor c on the front end side of a main body frame b having caster type wheels a at the front.
And a driven drum e on the rear end side, a polishing belt f is laid between the drums d and e, and an operation handle g is further provided on the body frame b.
In polishing the surface of the structural material h, while the motor c is being driven, the worker holds the operating handle g and presses the polishing belt f on the driven drum e side against the structural material h. Moreover, the entire polishing apparatus is moved forward along the marks formed on the surface of the structural material h in advance to remove the surface deposit i on the surface of the structural material h.
In the figure, j indicates a cover provided above the polishing belt f.

[0005]

However, the conventional polishing apparatus described above has various problems as follows.

That is, in the conventional polishing apparatus, since the worker polishes the surface of the structural material h while pushing and moving the polishing apparatus along the mark, the work efficiency is very poor and the work is difficult. The work environment is very bad because of the heavy labor and the generation of a large amount of dust and noise and vibration during the work, and the dust generation adversely affects other work. It was

The present invention has been made in view of the above-mentioned problems of the prior art, and it aims to improve the work efficiency and achieve a good working environment by automating the work of removing the deposits on the surface of the structural material by polishing. The purpose is to
