4. A hoisting method applied to the hoisting device of the fabricated air-void sandwich panel according to any one of claims 1-3, characterized in that: The steps include the following steps: Step one, according to the clamping length of the hollow sandwich panel, the clamping frames (8) are assembled, the front end and the rear end of the two clamping frames (8) are connected, the adjacent two clamping frames (8) are fixedly connected by cooperating with the connecting steel plate (14), the adjusting screw rods (11) in the interiors of the adjacent two clamping frames (8) are connected by the connecting prism and the connecting inner groove, and finally the fixed frame (13) and the connecting steel plate (14) are fixedly provided on the front and rear ends of the assembled clamping part by bolts, so that the front end of the adjusting rod member in the clamping part is connected with the rotating sleeve (18) in the interior of the fixed frame (13), and the rear end of the adjusting rod member is connected with the connecting sleeve (17) in the interior of the driving frame (12). Step two, after clamping the side edge of the hollow sandwich plate with the clamping part, the output shaft of the motor (16) is controlled to control the rotation of the adjusting rod in the movable slot (10), and the adjusting rod is rotated in the two adjusting blocks (9). Because the two adjusting blocks (9) are provided with inner threaded holes with opposite rotation directions, when the adjusting rod rotates clockwise, the two adjusting blocks (9) displace forward and backward along the inside of the movable slot (10), and the lifting center of gravity of the hollow sandwich plate is adjusted by adjusting the forward and backward position of the two adjusting blocks (9) on the top of the clamping part.
