The present invention relates to a variable wheel of a self-propelled vehicle traveling on a sewage pipe. The variable wheel of the self-propelled vehicle traveling on the sewage pipe of the present invention comprises a plurality of pivoting rakes whose longitudinal ends are rotationally connected to a driving shaft for rotating a traveling wheel of the self-propelled vehicle. When the self-propelled vehicle travels through a section of the pipe in which a sludge is deposited, the plurality of pivoting rakes are rotated in one direction on the driving shaft and unfolded on the driving shaft. When the self-propelled vehicle travels on a section of the pipe having the flat road surface, the plurality of pivoting rakes are rotated in different directions on the driving shaft and are retracted to have a curvature corresponding to a circumferential curvature of the traveling wheel. An objective of the present invention is to provide the variable wheel of the self-propelled vehicle traveling on the sewage pipe, which is configured so that a traveling body can easily travel between the section of the pipe in which the sludge is deposited and the section of the pipe having the flat road surface.
본 발명은, 하수관로 자주차의 가변형 바퀴로서, 상기 자주차의 주행용 바퀴를 회전시키기 위한 구동축에 길이방향 일단이 회동 가능하게 연결되는 다수개의 회동갈퀴를 포함하며, 상기 자주차가 슬러지가 퇴적된 관로의 구간을 주행하면, 다수개의 상기 회동갈퀴는 상기 구동축 상에서 일방향으로 회동되어 상기 구동축에서 펼쳐지고, 상기 자주차가 평탄한 노면이 형성된 관로의 구간을 주행하면, 다수개의 상기 회동갈퀴는 상기 구동축 상에서 타방향으로 회동되어 상기 주행용 바퀴의 둘레 곡률과 대응되는 곡률을 가지도록 오므려지는 것을 특징으로 한다.
