The invention discloses a high-speed train brake device. A brake block holder (3) and a brake block holder mounting seat (1-1) are hinged through a shaft hole (3-1); and the device further comprises a piston (2) arranged in a piston hole (1-2) of a brake box (1); and a limiting seat (2-1) is arranged at the upper end of the piston (2), and two driving rods (2-2) leaning out of the brake box (1) are arranged at the lower end of the piston (2). The device further comprises a crank located in the brake box (1), and the driving rods (2-2) are in transmission connection with a connecting rod shaft neck of the crank. The outer end of the crank stretches out of an opening in the front end of the brake box (1), and the crank is connected with the brake block holder (3). In the braking process, an air cylinder drives the piston to move, and the piston drives the crank to move through the driving rods, and therefore the brake block holder connected with the crank together is close to a wheel, and a brake block rubs with the wheel to achieve the braking aim. By means of the manner, the high-speed train braking device can meet the brake requirement of a train for high-speed driving of the train. The whole brake distance is short, and use is safer.
