Anti-rollover safety device applicable to horizontal type horizontal loop mobile vehicle

The invention discloses an anti-rollover safety device applicable to a horizontal type horizontal loop mobile vehicle. The device comprises a base and anti-rollover units. The base is fixedly connected to the frame of the mobile vehicle; every anti-rollover unit comprises a horizontal wheel set and anti-rollover hooks, and the horizontal wheel set and the anti-rollover hooks are correspondingly arranged on the base and are in a hook snapping clamp type matching mode relative to steel rails. By means of the matching structure of the horizontal wheel sets and the anti-rollover hooks, the anti-rollover safety device is arranged at the bottom of the loop mobile vehicle, namely, the horizontal wheel sets are symmetrically arranged on the outside contact surfaces and the inside contact surfaces of the rails, and the anti-rollover hooks are symmetrically arranged on the outside contact surfaces and the inside contact surfaces of the rails, so that the hoop mobile vehicle can move close to the rails all the time, sta
