The invention discloses a ladder climbing mechanism, wherein the ladder climbing mechanism comprises a front vehicle body, a back vehicle body and a driving device, wherein a pair of first climbing wheels is arranged at the front part of the front vehicle body; a pair of second climbing wheels is arranged at the back part of the front vehicle body; a pair of third climbing wheels is arranged at the front part of the back vehicle body; a pair of fourth climbing wheels is arranged at the back part of the back vehicle body; the front end of the back vehicle body is hinged to the back end of the front vehicle body; when the ladder climbing mechanism is driven on a flat ground, the back vehicle body and the front vehicle body are connected in a V form; the wheel bases between the third climbing wheels and the first climbing wheels are at least equal to the heights of steps; the total length of connecting the back vehicle body with the front vehicle body is less than the widths of the steps; and the driving device is used for driving the four pairs of climbing wheels to rotate. The ladder climbing mechanism not only can climb a ladder, whose step widths are greater than the total length, but also can be smoothly and quickly driven on the ground; and the ladder climbing mechanism is simple in structure, and is convenient to use.
