Problems solved by technology
[0003] After the converter is installed, the secondary dust removal pipeline is mostly designed along the direction of the original dust removal pipeline. Since the secondary dust removal square pipe has a large cross-section and passes through the middle of the plant structure, the space is limited. If the traditional method is used for installation, there will be more high-altitude operations and safety. High risk, low work efficiency, long installation period and high construction cost

The invention discloses a hook for rapid installation of a large-diameter dust removal square tube and a using method of the hook, and relates to the technical field of installation of steel-making secondary dust removal square tubes. The hook for rapid installation of the large-diameter dust removal square tube comprises a shell, an inner cavity of the shell is movably connected with a movable wheel through a rotating shaft, a steel wire rope is wound around the movable wheel, a hook body is arranged at the bottom of the shell in a penetrating mode, and the top end of the hook body penetratesthrough the bottom of the shell and is movably connected with a displacement block through a rotating shaft. According to the hook for rapid installation of the large-diameter dust removal square tube and the using method of the hook, the hook and the using method are improved, the operation method is simple and reasonable in structure, the installation efficiency and quality of the secondary dust removal square tube of a converter are effectively improved, moreover, the high-altitude butt welding operation of the dust removal square tube is reduced, the construction period is shortened, theconstruction cost is reduced, and meanwhile, the situation that the hook is damaged caused by the overlarge change of the acting force applied to the hook in the operation process is avoided.
Description
Technical field [0001] The invention relates to the technical field of steel-making secondary dust removal square pipe installation technology, in particular to a hook for rapid installation of large-diameter dust removal square pipes and a use method thereof. Background technique [0002] In the existing steelmaking environmental protection upgrade installation project, in order to meet the needs of technology upgrade and increase production capacity, the secondary dust removal system of the converter is basically expanded and installed at the original secondary dust collector position. [0003] After the converter is installed, the secondary dust removal pipeline is mostly designed along the direction of the original dust removal pipeline. Due to the large section of the secondary dust removal square tube and passing through the middle of the plant structure, the space is limited. If the traditional method is used for installation, there will be more high-altitude operations and s...
