The invention relates to an elevator car type elevator landing door device. The elevator car type elevator landing door device comprises an upper ridge frame, a landing door hanging plate, a door hanging wheel, a pressing wheel and a door lock device installed on the upper ridge frame. The pressing wheel is fixed to the landing door hanging plate. The elevator car type elevator landing door device is characterized in that the upper ridge frame is of an integrated extrusion forming structure, and the upper ridge frame comprises an upper section part and a guide rail extending downwards from the upper section part; and the guide rail is in an S shape, the guide rail downwards extends to form a vertical extending section, the head of the vertical extending section is upwards inflected by 180 degrees to form a guiding edge and an inflecting edge, and a U shape is formed by the vertical extending section, the guiding edge and the inflecting edge. The designed upper ridge frame structure is applied to an elevator car type elevator landing door, the door hanging wheel is hung and connected through the guide rail, the pressing wheel is connected to the bottom plane of the guiding edge, and therefore the rolling track of the pressing wheel is limited. By means of the elevator car type elevator landing door device, the technical problem of the using safety performance of an existing landing door device is solved, and the stability of the elevator car type elevator landing door is improved.
