Double-layer building material protective shed with ceiling capable of being rapidly moved

The utility model relates to a double-layer building material protective shed capable of quickly moving a ceiling, which comprises a protective shed main body fixed on the ground, an upper-layer fixed ceiling is fixedly mounted at the rear section of the top of the protective shed main body, a lower-layer ceiling is slidably arranged at the front section of the top of the protective shed main body, and pulleys are mounted at the lower end of the lower-layer ceiling. The lower-layer ceiling slides along the sliding rails through the pulleys to be retracted to the lower side of the upper-layer fixed ceiling, and the front electric winch and the rear electric winch are connected with the front end and the rear end of the lower-layer ceiling through steel cables correspondingly. An upper-layer structure and a lower-layer structure are adopted, the front-section lower-layer ceiling can be rapidly moved to be opened and closed through the front electric winch and the rear electric winch, construction is convenient,
