A DUCT-CLEANING ROBOT TO MOVE VERTICALLY BY COMPOUND MOTION

摘要

A duct-cleaning robot moved vertically by compound motion has a radial supporting frame supporting the cleaning robot in the duct so that the robot cleans the inside of the duct by moving vertically and straightly. A duct-cleaning robot moved vertically by compound motion comprises brushes, a brush driving motor, a body having the brushes, the brush driving motor, and wheels(2), a drive motor for driving the wheels, a radial supporting frame, a supporting frame driving unit, and a plurality of supporting frames Installed to the front part of the body, the radial supporting frame contacts with the inner wall of a vertical duct. The radial support frame includes a center bar, a supporting flange, an operating flange, a flange drive motor, a pinion gear, a plurality of settling stands, and a plurality of supporters. The supporting flanges are fixed to the center bar. The operating flange reciprocates along a rack gear formed on the center bar. The flange motor and the pinion gear are mounted to the operating flange. The settling stands are combined with the operating flange. The supporters are combined with the supporting flange at one end and to the settling stand at the other end.
