The invention relates to a vertical lifting door locking device. The device comprises a mounting base. A door locking mechanism and a door lock self-locking mechanism are arranged on the mounting base. The door locking mechanism comprises a first electromagnet fixed to the mounting base and a locking assembly connected with a first push rod of the first electromagnet. Attraction connection and disconnection of the first electromagnet drive the locking assembly to move. The door lock self-locking mechanism comprises a manual opening assembly and a hanging connection assembly. The manual openingassembly comprises a rotary shaft rotationally arranged on the mounting base and a first locking plate fixed to the rotary shaft, and an opening hole is formed in the rotary shaft. The hanging connection assembly comprises a second electromagnet fixed to the mounting base, a second locking plate rotationally arranged on the mounting base, and a connecting rod. One end of the connecting rod is connected with a second push rod of the second electromagnet, and the other end of the connecting rod is arranged in a slide groove of the second locking plate in a sliding mode. The second locking plateis matched with the first locking plate, the first locking plate is driven and can shift the locking assembly to move, the first locking plate and the second locking plate are in hanging connection,and self-locking is achieved.
