The use method (working principle) of the invention is as follows:

when the bridge floor part 1 is required to be hoisted, the left part and the right part of the upper fixing plate 2 are separated, the lower fixing plate 12 is placed at the bottom of one end of the bridge floor part 1, then the balance cavity 5 is attached and fixed to the two sides of the bridge floor part 1 respectively, after the attachment and the fixation are finished, the upper fixing plate 2 is closed through a manual bolt, then the fixing belt 3 is fixedly installed in the hanging part 4, and the steps are repeated to install the balance device at the other end of the bridge floor part 1 again.

After the balancing device is installed, if the bridge deck component 1 rises to the high altitude, when wind blows, external wind force extrudes the air bag 13, the air bag 13 is sunken inwards, internal gas of the air bag respectively passes through the large through hole 6 and the small through hole 7, the aperture of the large through hole 6 is far larger than that of the small through hole 7, the gas almost completely enters the upper part of the balancing cavity 5, the rushing gas extrudes the adjusting magnetic block 9 to separate the adjusting magnetic block from the limiting plate 10, the air bag moves downwards along the balancing rod 8 and is absorbed by the magnetic block, the balancing magnetic block 11 is adsorbed to move outwards, the weight increment of a supporting point between the fixing band 3 and the upper fixing plate 2 is realized, the transverse blowing force of the wind force on the supporting point between the fixing band 3 and the upper fixing plate 2 is balanced and offset, and the wrapped and fixed bridge deck component 1 is ensured to be stable and.
