The invention discloses a high-speed shot-blasting auxiliary device of a high-speed rail brake system. The high-speed shot-blasting auxiliary device comprises a shot-blasting pot, a fixed base, an electropneumatic proportional valve, a shot-blasting adjusting base and a gas path system. The shot-blasting pot is mounted on the fixed base through supports. The electropneumatic proportional valve is fixedly arranged on the fixed base between the supports. A numerical control shot valve is arranged between the electropneumatic proportional valve and the shot-blasting pot. The gas path system is connected between a sidewall of the shot-blasting pot and one end of the electropneumatic proportional valve. The other end of the electropneumatic proportional valve is connected to a spray gun through a sand-blasting hose. The spray gun is arranged on the shot-blasting adjusting base. The shot-blasting pot is also provided with a sand-shot heater. By a high-speed shot-blasting technology, a track at the bottom of wheels is shot-blasted so as to instantaneously increase surface friction coefficient of the track, raise adhesive force between the wheels and the track and guarantee non-slip of the wheels. The technology is safe and reliable. Sand-shot in the shot-blasting pot is heated at regular intervals. Therefore, there is no caking phenomenon during emergency use of sand-shot, and safe braking is realized under the circumstances of snow and rain and slippery ground, greasy dirt on the track, wheel slipping, auxiliary brake when entering and leaving a station and speed transformation.
