The invention provides a construction elevator protective door and a linkage type frame erecting and door opening device, the protective door comprises a door frame and two door leaves, the door leaves are installed at the door frame through a locking structure, the locking structure comprises a supporting frame and a clamping and locking mechanism, and the clamping and locking mechanism forms clamping and locking on the closed door leaves; a magnet block is arranged on the clamping and locking mechanism, and the door opening state is maintained in a magnetic attraction mode; the bottom end of the supporting shaft is sleeved with a torsional spring, and elastic force is provided for door closing reset of the door leaf. The frame erecting and door opening device is installed on the elevator car, the pushing frame can stretch out and be correspondingly inserted into the locking structure, a frame erecting of the elevator car and the door frame is formed, the clamping and locking mechanism is unlocked, and the magnet block is made to move to the corresponding position where the door leaf is attracted through subsequent magnetic attraction. Automatic resetting and locking can be achieved, manual operation is reduced, and use is convenient. And the frame erecting and door opening device not only can realize the unlocking action of the protective door, but also can realize the connection between the elevator car and the protective door, so that the overall matching is enhanced, and the use safety is improved.
