Dust-free operation method based on dustproof operation shed

The invention discloses a dust-free operation method based on a dustproof operation shed. The method is used for assembling equipment inside the dustproof operation shed. The dustproof operation shedcomprises an inner steel frame, a dustproof cover and a dustproof fabric assembly; the inner steel frame comprises a plurality of adjusting bases, a stretchable rod assembly and transverse beams. Thedust-free operation method comprises the following steps of adjusting the height of the adjusting bases so that the upper surfaces of the adjusting bases can be located on the same plane; adjusting the length of the stretchable rod assembly so that the transverse beams can be located at the same height; opening the top of the dustproof cover; lifting the equipment into the dustproof cover from thetop of the dustproof cover or performing lifting displacement before equipment assembling inside the shed; assembling the dustproof fabric assembly into the inner steel frame so as to form the installation space, and adjusting
