A maintenance device for the inner side of an inverted Y-shaped tower column of a cable-stayed bridge that can be moved in three directions. The hanging point device in the tower is stuck in the middle of the inverted Y-shaped tower column by gravity. The hanging point device in the tower includes an annular frame, a track, and an electric running wheel. The track is arranged below the annular frame in the transverse direction of the bridge. The electric running wheel is stuck on the track and can move along the track in the transverse direction of the bridge. The suspended operating platform has two sliding hanging baskets symmetrically hung on both sides of the middle hanging basket and can slide along the bridge along the middle hanging basket. The hanging rope connects the suspended operating platform with the hanging point device in the tower, driving the suspended operating platform to be lifted and lowered vertically. The maintenance equipment of the present invention does not need to set anchors on the tower column because the hanging point device in the tower is stuck in the middle of the tower column by gravity, thereby reducing the impact on the tower column structure. The suspended operating platform can move in three directions, avoid interference from the inclined cable, and can achieve full coverage maintenance of the inner side of the inverted Y-shaped tower column. During maintenance construction, due to the small construction impact range, the impact on bridge deck driving is small.
