The invention relates to the technical field of semitrailer trains, and discloses an anti-rollover and multi-stage anti-folding device of a semitrailer train, which comprises a first connecting mechanism and a second connecting mechanism, each of the first connecting mechanism and the second connecting mechanism comprises a connecting frame, a fixing plate, a U-shaped bolt and a nut, a semitrailer chassis is connected between the connecting frame and the fixing plate, and the U-shaped bolt sleeves the connecting frame; the two ends of the U-shaped bolt penetrate through the fixing plate to be connected with nuts. The first buffer mechanism and the second buffer mechanism are connected between the first connecting mechanism and the second connecting mechanism; the first buffer mechanism and the second buffer mechanism comprise buffer pieces arranged close to the traction head side, and side wheels are arranged on the side, away from the second buffer mechanism, of the first buffer mechanism and the side, away from the first buffer mechanism, of the second buffer mechanism; the auxiliary braking mechanism is used for braking rear wheels of the semitrailer train; and a trigger switch for controlling the auxiliary brake mechanism is arranged on the buffer piece. The anti-rollover and multi-stage anti-folding device has the advantages that the anti-rollover and anti-folding effects are good, and the original structure of the train is not damaged.
