The invention discloses a rotary locking device and a self-unloading vehicle having same; the rotary locking device comprises a clamp part arranged on a self-unloading vehicle tail door and a limit part arranged on a position, matched with the clamp part, of a tail door frame; the clamp part and the limit part can be at a locking and loosening state after relative motions; when the door needs to be locked, the limit part rotates so as to attach to the clamp part, so the two parts are locked, the limit part can limit the motions of the tail door, and the tail door cannot be opened by errors; when the door needs to be opened, the limit part rotates to a position with certain distance from the clamp part, so the two parts are in the loosening state, the limit part cannot limit the motions of the door, and the tail door can be easily opened. The rotary locking device can use the clamp part and limit part to effectively clamp and lock, is obvious in effect, simple in structure, and low in making cost.
