9. The application method of the special-shaped main truss construction splicing device, which is characterized in that the special-shaped main truss construction splicing device is as claimed in claim 8, and comprises the following steps:
s1: the climbing mechanism (2) is sleeved on the periphery of the steel frame (1) in advance, and the steel frame (1) is installed at a proper position so as to prepare for welding between a truss lifted by the crane and the steel frame (1);
S2: by starting the climbing mechanism (2), the first motor (206) drives the rotating shaft (207) to rotate, and the two first gears (209) respectively drive the two second gears (210) and the rotating rod (202) to rotate while the rotating shaft (207) rotates, so that the roller (203) is attached to the outer surface of the steel frame (1) to rotate, and climbing is realized;
S3: the climbing mechanism (2) further drives the supporting table (3) to ascend to the top end of the steel frame (1), the second motor (401) drives the first driving wheel (402) and the second driving wheel (403) to rotate through the driving component (4), and the first fluted disc (404) is further rotated to drive the second fluted disc (5) and the adjusting component to rotate;
S4: when the rotating assembly drives the adjusting assembly to rotate around the truss, the truss is pushed to a proper position by driving the adjusting assembly, the air cylinder (9) is started to enable the output end of the air cylinder (9) to push the moving block (11) to advance, the moving block (11) drives the truss to move to a proper position gradually while advancing, and then the two clamping blocks (19) clamp the truss rapidly to finish the fixation of the truss;
S5: after the truss is clamped, the moving block (11) stops moving when moving to the leftmost end of the vertical block (8) along with the pushing of the air cylinder (9), at the moment, the movable block (10) drives the second connecting frame (14) and the clamping assembly to vertically move downwards along the guide groove (20) through limiting blocks (21) at two ends under the pushing of the air cylinder (9), and therefore butt joint between the truss and the steel frame (1) is completed rapidly.
