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 braking is conducted, at the moment, the friction piece on the track makes contact with the track to increase friction force, then the braking force of the track operation machine chassis is improved, and the effect of shortening the braking distance is achieved.

    本发明涉及制动领域,提供一种轨道作业机械底盘、制动方法和轨道作业机械,轨道作业机械底盘包括履带底盘和轨道移动机构。履带底盘的履带的外周面设置有摩擦件。轨道移动机构设置在履带底盘的底部,且用于驱动履带底盘上升至与轨道分离的第一位置或下降至与摩擦件与轨道接触的第二位置。当轨道作业机械需要沿轨道行走时,轨道移动机构驱动履带底盘上升至与轨道分离的第一位置,由轨道移动机构支撑并带动履带底盘沿轨道移动。当轨道作业机械需要制动时,可在制动的同时控制轨道移动机构驱动履带底盘下降至第二位置,此时履带上的摩擦件与轨道接触,以增加摩擦力,进而提升轨道作业机械底盘的制动力,实现缩短制动距离的效果。
