PROBLEM TO BE SOLVED: To provide an automatic traveling spray apparatus with excellent general purpose property capable of spraying a spray agent for a spray repair for an inner wall of a carbonization chamber of a coke furnace, for application of an agent to an iron bridge leg and a concrete leg and the like, and further for application to such heights.
SOLUTION: There are provided an automatic traveling vehicle 2 including an elevation mast 4 mounted thereon, and a spray attachment 6 vertically moving with the aid of the elevation operation of the elevation mast. The spray attachment includes a fluid supply pipe 18, to one end of which both of a spray agent supply source and a compression air supply source are switchably connected. An automatic traveling spray apparatus is constructed by connecting a spray nozzle 50 to one end of a fluid supply pipe and supplying the spray agent to the fluid supply pipe from the spray agent supply pipe. An air motor and a rotor rotated by the air motor are attached to the one end of the fluid supply pipe. The automatic traveling spray apparatus serves as a cleaning/cutting apparatus for adjusting a partial surface of a surface to be sprayed by mounting an air motor on the one end of the fluid supply pipe and a rotator rotating by the air motor, and supplying compression air to the fluid supply pipe from the compression air supply source.
