The invention discloses high-speed train safety devices (pulleys at four corners). The pulleys at the four corners are designed at the four corners below a carriage (1); the pulleys (2) mounted at the four corners are the most powerful parts of the safety devices for train protection, and occurrence of accidents can be avoided only by small power; pulley supports (4) are welded and mounted below a ring beam (3) under the carriage, pulley position adjusters (5) are mounted at the lower sections of the supports (4) and can adjust pulley shafts (6) to move vertically and horizontally, then certain distance can be kept among each carriage of the train, a first pulley (2) of each carriage and a guard tail along the way, and the pulleys cannot work if no accidents happen. The defects in the prior art are overcome, the operation is convenient, and the train safety is guaranteed.
