That is, in this device, since the traveling wheels connected to the traveling air motor via the differential gear mechanism are provided on the supporting legs that are wide open, the curve or the inclination is combined with the action of the upper pressing wheel. Even if it is a pipe line, there is no risk that the traveling wheels will float or slip from the inner surface of the pipe line, or the traveling wheels will excessively slide on the inner surface of the pipe line and be scratched, and always stable and smooth running The state can be realized. Therefore, during the traveling, the revolving air motor 70 is driven to rotate the revolving arm 50 at a low speed, and the pilot type switching valve 54
By opening a and 54b and spraying the paint from the paint spray nozzles 53a and 53b, the inner surface of the pipe can be easily coated by remote control.

る。The supporting legs 3 and 5 can be replaced by removing the bolts 10 if the supporting legs 3 and 5 having different lengths are separately prepared in advance, which facilitates the coating of pipes having different diameters. Can be dealt with. Further, this device can be used for cleaning and cleaning the inside of the pipe by providing a nozzle for spraying cleaning water at a high pressure in place of the above-mentioned paint spraying nozzle on the swivel arm 50.
