The invention discloses a two-way intelligent vertical elevator stall protection device, which relates to the technical field of elevator safety facilities, and is provided with a rack, a wheel disc, a brake mechanism and a shifting mechanism, the rack is fixedly installed in an elevator car, the wheel disc is fixedly connected with the rotating shaft and rotationally installed on the rack through the rotating shaft, and the steel wire rope is tensioned and wound around the wheel disc. The brake mechanism comprises a swing frame, a swing shaft and a pressing block; the swing frame is located on the side of the wheel disc and rotationally installed on the rack through the swing shaft, and the pressing block is fixedly installed on the swing frame. Rotation of the wheel disc inevitably accompanied by running of an elevator is used as main power, the pressing block is driven to press the steel wire rope hanging the elevator car to achieve mechanical braking of the elevator car, the braking control process only includes that the stepping motor drives the pawl to rotate, the braking response speed is high, efficiency is high, stability is good, the structure is simple, and use is convenient. And the braking action is rapid, accurate and stable, and good practicability and application prospects are achieved.
