The invention discloses an automatic construction elevator door opening and closing device which comprises an elevator door and an outer cage frame, a car cam is arranged on the outer cage frame, and a stop plate and a limiting piece are arranged at the top of a door frame; the end, close to the door frame, of the stop plate is rotationally connected with one side of the door frame and provided with a door top abutting against the side face of the elevator door, the side, away from the door frame, of the stop plate is rotationally provided with a door lock assembly, and a limiting groove clamped with the limiting piece in a limiting mode is formed between the fixed end and the free end of the door lock assembly. The free end of the door lock assembly corresponds to the cam, and when the free end of the door lock assembly makes contact with the cam, clamping of the limiting groove and the limiting piece is canceled. The elevator door can be automatically jacked and locked in the lifting operation process of the elevator, so that the elevator door is effectively prevented from being opened in the lifting operation process of the elevator, and the safety of workers in the elevator is guaranteed; and after the elevator stops, the elevator door can be automatically unlocked, so that the elevator door can be smoothly opened.
