step two: when the gantry crane moves along the track, the second limiting assembly (15) moves along the adjusting steel rope (16) through the third guide wheel (18) and the rotating column (19), the adjusting steel rope (16) is kept in a tightening state under the action of the winch, the limiting clamp plates (20) are driven to move on the rotating column (19) through the operation of the pneumatic cylinder (21), the two limiting clamp plates (20) clamp and fix the adjusting steel rope (16), the fixed connection of the second limiting assembly (15) and the adjusting steel rope (16) is realized, the adjusting steel rope (16) is always in a triangle shape between the gantry crane frame and the ground, and further the gantry crane is reinforced and connected through the adjusting steel rope (16);
step three: the second motor (24) works to drive the first rotating teeth (25) to rotate, the meshed second rotating teeth (26) are driven to rotate, rotation of the rotating arm (27) is achieved, the third motor (33) works, the two third rotating teeth (34) are driven to rotate through chain teeth (35) and chain transmission, the second supporting arms (31) are driven to move along the first guide rail (29) in cooperation with the two meshed first racks (30) and the second racks (37), the third supporting arms (36) move along the second guide rail (32), unfolding and folding of the first supporting arms (28), the second supporting arms (31) and the third supporting arms (36) are achieved, the first supporting arms (28), the second supporting arms (31) and the third supporting arms (36) are unfolded to be in contact with the ground, and at the moment, the third windproof mechanism (3) is triangular with the ground and plays a role in reinforcing and supporting the gantry crane frame.
