step three: starting a third rotating motor (22) to enable a connecting rope (24) to be lowered, clamping a first clamp half gear (26) on one side of the head end of an impeller (43), correspondingly splicing a second clamp half gear (29) on the other side of the head end of the impeller (43), then screwing an upper connecting screw (27) in a first positioning block (25) and a second positioning block (28) in a penetrating manner, and screwing a lower connecting screw (32) in a third positioning block (30) and a fourth positioning block (31) in a penetrating manner;
step four: starting a vacuum pump (33) to generate negative pressure in the vacuum adsorption cover (37) so as to be adsorbed on the surface of the impeller (43), and then starting a second rotating motor (15) and a third rotating motor (22) to lift the impeller (43);
step five: a fourth rotating motor (39) is started, the fourth rotating motor (39) drives a transmission gear (41) to rotate through a transmission rod (40), and the transmission gear (41) is meshed to drive a first hoop half gear (26) and a second hoop half gear (29) to rotate, so that the impeller (43) can be adjusted in angle after being hoisted;
step six: driving the clamping seat (3) to rotate through a rotating device, enabling the mounting hole (421) of the hub (42) to rotate to face the impeller (43), and repeating the fifth step to enable the impeller (43) to be finally aligned with the mounting hole (421);
step seven: installing the impeller (43) in the installation hole (421);
step eight: and repeating the second to seventh steps until all the impellers (43) are installed in the installation holes (421) of the hub (42).
