The mobile platform for large-scale building facade construction according to claim 8, wherein: the stabilizing mechanism (4) further comprises a supporting arm and a second supporting rolling piece (401), one end of the supporting arm is connected with the outer frame (2), and the other end of the supporting arm is connected with the second supporting rolling piece (401); the second wind-resistant mechanism further comprises a rotating arm (402) and a fixing frame (403), wherein the rotating arm (402) is connected to the supporting arm in a shaft mode, one end of the rotating arm (402) is hinged with the fixing frame (403), and a pin joint mechanism is arranged between the other end of the rotating arm and the supporting arm; the limiting mechanism further comprises a limiting pin (204), the outer frame (2) is provided with a slide way, the limiting pin (204) is in sliding connection in the slide way, and the end part of the limiting pin (204) is in sliding connection with teeth of the flywheel (203).
10. A method of constructing a mobile platform for constructing a facade of a large building according to claim 1, comprising the steps of:
step 1, hanging a transverse frame of an outer frame (2) on a cross beam (101) of a wall body (1) to be constructed, wherein a travelling wheel (206) is arranged on the top surface of the cross beam (101), a first supporting rolling element (2072) of an obstacle avoidance windmill (207) is arranged on the inner side of the cross beam (101), and a second supporting rolling element (401) of a stabilizing mechanism (4) is arranged on the wall body (1);
step 2, constructors enter a lifting platform of the inner frame (3), a motor (208) is started, and the motor (208) drives a transmission screw (209) to rotate, so that the inner frame (3) is lifted;
step 3, after reaching the working platform (202) at the working height, the constructor works on the lifting platform or the working platform (202);
step 4, after the construction of the current part is completed, a constructor pulls a transmission belt (210) or a transmission chain to drive a flywheel (203) and a fixed wheel (211) to rotate, the flywheel (203) drives a travelling wheel (206) to rotate, the travelling wheel (206) travels along a cross beam (101), when the travelling wheel travels to a longitudinal beam (102), the longitudinal beam (102) blocks a current opposite obstacle avoidance arm (2071) to enable the obstacle avoidance windmill (207) to rotate, and the obstacle avoidance arm (2071) above the longitudinal beam (102) spans across the longitudinal beam (102) to realize obstacle avoidance;
and 5, when the wind weather is met, constructors push the limiting pins (204) to slide, so that the limiting pins (204) are inserted between teeth of the flywheel (203), the flywheel is prevented from rotating, the flywheel enters the lifting platform to descend to the bottom layer, the rotating arm (402) rotates, and the fixing frame (403) is ejected to be in contact with the wall surface (1) and is fixed through the pin joint mechanism.
