9. A method of lifting a structural asymmetric building panel lifting device as claimed in claim 8, including the steps of:
s1, before the asymmetric building board is hoisted, the distance between two adjusting plates (23) is adjusted according to the size of the asymmetric building board, in the specific adjusting process, a switch of a double-shaft motor (18) is pressed down, two screw rods (19) rotate along with two output shafts of the double-shaft motor (18), the rotation of the screw rods (19) is converted into the transverse movement of a driving block through the threaded connection relation between the arranged screw rods (19) and thread grooves, and then the distance between two connecting lugs (33) can be adjusted, so that the asymmetric building boards with different sizes can be hoisted conveniently;
s2, after the position of the connecting lug (33) is adjusted, the position of the lifting lug (15) is adjusted according to the mass of two sides of the asymmetric building board, a switch of a driving motor (25) is pressed down, a gear (26) and a vertical shaft are rotated, the rotation of the gear (26) is converted into the transverse sliding of a vertical plate (28) and the lifting lug (15) through the meshing relation of the gear (26) and a rack, the transverse position of the lifting lug (15) is changed, and further the mass balance lifting of the asymmetric building board can be realized;
s3, after the position of the connecting lug (33) and the lifting lug (15) is adjusted, a switch of the lifting motor (6) is pressed down, a driving disc (7) rotates along with an output shaft of the lifting motor (6), the driving disc (7) drives a cam (8) to rotate, arc motion of the lifting arm (5) is achieved through a driving plate (9) arranged on one side of the cam (8) according to a lever principle, then the asymmetric building board is lifted, the adjusting motor (10) is started in the lifting process, the output shaft of the adjusting motor (10) can drive a driving wheel to rotate, linkage of a synchronizing shaft (11) and the output shaft of the adjusting motor (10) is achieved through the driving relation between the driving wheel and a driven wheel, the lifting plate (14) is kept in a vertical position all the time in the lifting process through two adjusting rods (13), and safety accidents caused by gravity center change of the lifting plate (14) are avoided.
