The invention discloses a brake device with integrated safety tongs and lifting mechanism. The brake device comprises the two safety tongs, and movable wedge blocks and side plates are arranged on the safety tongs. The lifting mechanism comprises two rotating shafts, two shifting forks and two short pull plates. The rotating shafts penetrate the side plates of the safety tongs on the same sides in a running fit manner. The parts, in the safety tongs, of the rotating shafts are fixedly connected with the first ends of the shifting forks, and the second ends of the shifting forks can jack up the movable wedge blocks upwards. The parts, outside the safety tongs, of the rotating shafts are fixedly connected with the first ends of the short pull plates, the second ends of the short pull plates on the two sides are each in running fit with one end of a connecting mechanism, and the short pull plates on the two sides are opposite in direction. The outer end of one rotating shaft is fixedly connected with the first end of a long pull plate, and the second end of the long pull plate is in running fit with a lifting head. Mounting efficiency and assembling precision are improved, and the safety risks on construction sites are reduced.
