Driving structure of large sliding soundproof door

The utility model discloses a driving structure of a large sliding soundproof door, which comprises an electric driving wheel and an air spring, the electric driving wheel is connected with a door leaf through an air bag of the air spring, the positive pressure between the electric driving wheel and the ground is adjusted by adjusting the inflation pressure of the air spring, and the door leaf is opened and closed according to ascending, moving and descending. The utility model has the advantages that the opening and closing mode is more reasonable, the opening and closing action mode of the gate is as follows: rising-moving-falling, the air floating mode enables the horizontal moving friction force to be minimum, no gap exists between the gate leaf and the ground in a closed state, the sound insulation index is ensured, and the electric driving wheel is a better mode for providing horizontal thrust for the translation of the gate, so that the safety of the gate is improved. And the overall structure and mode
