The invention is applicable to the field of hoisting of automatic fire extinguishers special for pipe galleries, and provides a flange structure for hoisting of automatic fire extinguishers special for pipe galleries, which comprises a flange, the middle of the flange is provided with a flange interface, and the flange is provided with four first mounting grooves and four second mounting grooves along the circumferential direction of the flange interface; the first mounting grooves and the second mounting grooves are strip-shaped grooves, the two ends of each first mounting groove and the two ends of each second mounting groove are arc-shaped, and the first mounting grooves and the second mounting grooves are formed along the flange connector at equal intervals. The distances between the centers of the arc-shaped faces at the two ends of the first installation groove and the center of the flange connector are 25 mm and 65 mm respectively. The distances between the centers of the arc-shaped faces at the two ends of the second installation groove and the center of the flange connector are 25 mm and 45 mm respectively. The flange structure for hoisting the automatic fire extinguisher special for the pipe gallery is novel in structure and has the advantage of being small in structural size compared with an existing normal flange plate.
