The invention relates to the technical field of landscape tower maintenance, in particular to a tower climbing device. The tower climbing device comprises a first connecting rope and a second connecting rope, wherein one end of the first connecting rope and one end of the second connecting rope are connected to the bottom face of an upper-layer plate of a landscape tower, spacing is reserved between the connecting ends on the first connecting rope and the second connecting rope, stepping rods are connected between the first connecting rope and the second connecting rope, and the multiple stepping rods are evenly distributed in the vertical direction; and the tower climbing device further comprises a storage device for storing the first connecting rope, the second connecting rope and the stepping rods along the bottom face of the upper-layer plate of the landscape tower and the inner side wall of the landscape tower. The multiple stepping rods evenly distributed in the vertical direction are mounted through the first connecting rope and the second connecting rope, and through the stepping rods, maintenance personnel can step the stepping rods to climb to the high position for maintaining and replacing the landscape tower. When the tower climbing device does not need to be used, the first connecting rope, the second connecting rope and the stepping rods are stored along the bottom face of the upper-layer plate of the landscape tower and the inner side wall of the landscape tower, and the influence on the sightseeing experience of tourists is avoided.
