Pipe Inside Blasting Machine

The present invention relates to a pipe inner surface blasting device, by the insertion into the After setting for different pipe diameter pipe do the blasting work to be carried out before the coating operation of the pipe inner surface can be performed quickly and elaborate blasting operation and unskilled one who It has a pipe inside the blasting apparatus that can easily be a blasting operation to provide. Wear of the feed shaft 20, the feed shaft 20 is inserted into the side steel grit moving the transfer shaft 20, the present invention is that the flow channel role of steel grit that the inner peripheral surface injection during blasting pipe to achieve above object, of the sleeve 60 to be prevented, the transfer shaft 20 is attached to the sleeve 60 inside, the steel grit is injected with the nozzle unit 10 for blasting the pipe inner surface, said transfer shaft (20) the first guide bracket (70a) and the feed shaft 20, the second guide brackets (70b) fitted to the outside to enable the lateral moving along with the first guide bracket (70a) formed along the one end periphery and the second guide brackets (70b) a plurality of both ends of the hinge an "X" cross-connected in-shape on the outer peripheral surface of one roller guide 40 and, rolling the roller along the pipe inner surface is attached to the roller guide 40, both ends 80, the second guide brackets ( And that is configured to 70b) and one feed shaft (handle 30 for adjusting sandwiched 20) so as to be in contact with the side surface, the transverse axis (a hose connector 50 is mounted to 20) other end to the technical aspect. Blasting, stationary nozzle, roller guide, roller, pipe diameter, sprinklers
