The invention relates to the field of braking, and provides a track operation machine chassis, a braking method and a track operation machine, and the track operation machine chassis comprises a crawler chassis and a track moving mechanism. Friction pieces are arranged on the peripheral face of a crawler belt of the crawler belt chassis. The track moving mechanism is arranged at the bottom of the track chassis and used for driving the track chassis to ascend to a first position separated from the track or descend to a second position in contact with the friction piece and the track. When the track operation machine needs to walk along the track, the track moving mechanism drives the track chassis to rise to a first position separated from the track, and the track moving mechanism supports and drives the track chassis to move along the track. When the track operation machine needs to be braked, the track moving mechanism can be controlled to drive the track chassis to descend to the second position while braki
