Technical Field

[0001] The utility model belongs to the technical field of construction engineering equipment, and in particular relates to a fast winding device for a dense mesh used in construction engineering. Background Art

[0002] Close-mesh safety nets are generally used in construction projects. Their main function is to provide safety protection for construction sites. They can effectively prevent the free fall of various objects on the construction site, thereby producing a buffering effect. Therefore, they are also called "close-mesh building safety vertical nets". They are the colored vertical nets that we usually see surrounding the entire building during construction. Most of them are green, and some are blue or very few other colors.

[0003] In order to reduce dust pollution, workers usually lay fine mesh nets on building materials at construction sites to prevent dust.

[0004] After checking the public (announcement) number: CN215625569U, a close-mesh net winding device for construction is disclosed. This technology discloses "a motor drives a gear, and the gear is meshed with a rack slidably connected to the inner wall of the first slot, thereby driving the sliding rod to move up and down. After the first support rod located at the front side is lowered to a suitable height, the winding drum is placed in a suitable place for transportation, and the winding drum can be taken out from the two first support rods." The technical effects include "making it convenient for workers to carry and achieving the purpose of saving manual labor for net collection";

[0005] However, the reeling device in the solution lacks the function of removing dust from the dense mesh when reeling it, resulting in a large amount of dust remaining on the dense mesh after reeling, which is inconvenient for the transportation, storage and secondary use of the dense mesh, and also causes dust to splash in the working environment;

[0006] In order to solve the above problems, the present application proposes a fast winding device for a dense mesh used in construction engineering. Utility Model Content
