The invention relates to the technical field of high-speed train braking, and discloses a high-speed train emergency braking device and method.The high-speed train emergency braking device comprises a support, a lifting driving mechanism arranged on the support and a frictional resistance part connected with the lifting driving mechanism, and the lifting driving mechanism is used for driving the frictional resistance part to make contact with a rail after descending; and the frictional resistance part is used for applying braking resistance to the high-speed train. The emergency braking device for the high-speed train has the following advantages and effects that when the emergency braking device for the high-speed train is used, the support is directly and additionally arranged on a train chassis, the design and layout of the train chassis do not need to be changed, and the emergency braking device can be applied to the train in use. The emergency braking device of the high-speed train can be integrally detached for repair, maintenance and replacement. The emergency braking device for the high-speed train can be applied to the high-speed train and can also be applied to rail vehicles such as a low-speed train, a subway and a tramcar, the braking distance of the train is effectively shortened during emergency braking, and the life and property safety of personnel on the high-speed train is effectively protected.
