<p><P>PROBLEM TO BE SOLVED: To provide an apparatus for washing the inside of a pipe which is capable of washing the inside of a plurality of pipes by one hose rotating device, wherein the inside of the pipes are washed by jetting a high-pressure fluid from a washing nozzle that is installed at the tip end of a high-pressure hose rorating around the center axis. <P>SOLUTION: The hose rotating device is equipped with: a motor; a driveshaft gear rotated by the motor; a plurality of intermediate gears that are installed around the driveshaft gear and that are meshed with the driveshaft gear to rotate; a plurality of follower gears which are meshed with each of the intermediate gears to rotate; and a shaft that is rotated together with the follower gears and connected to the high-pressure hose. The high-pressure fluid guided from the supply source of the high-pressure fluid is branched and guided to each shaft. The shaft supplies the high-pressure fluid while imparting rotation to the high-pressure hose, enabling the plurality of high-pressure hoses to be rotated by the one hose rorating device. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
