Problems solved by technology

With the growth of the furnace shell, the furnace diameter becomes smaller, and the traditional lifting tools are gradually cut radially toward the center of the furnace shell, so the general applicability is not strong, and most of them can only be used for hoisting operations of a blast furnace

Abstract

The invention discloses a furnace shell lifting tool for overhauling blast furnaces. The furnace shell lifting tool comprises an inner frame, lifting arms and lifting rods, wherein steel wire rope hydraulic jacks are fixedly connected with the inner frame through steel wire ropes so as to lift the inner frame; a plurality of lifting arms are detachablely fixed on the outer side of the inner frame;the top ends of the lifting rods are detachablely mounted on the lifting arms; the lower parts of the lifting rods are connected with the furnace shells of the blast furnaces so as to lift the furnace shells of the blast furnaces. The furnace shell lifting tool for overhauling the blast furnaces provided by the invention is capable of improving turnover and usage frequency; meanwhile, the applicability and the balance of the lifting tool are improved at the same time.

Description

technical field [0001] The invention relates to the technical field of blast furnace maintenance equipment, in particular to a blast furnace shell hoisting tool for overhauling. Background technique [0002] The replacement and installation of the blast furnace shell is an important work content of the blast furnace overhaul and renovation project in iron and steel enterprises, and it also directly determines the construction period of the renovation project. The main project of blast furnace ironmaking is often designed very compactly. Moreover, during the implementation of the blast furnace overhaul and renovation project, other supporting projects are not in production, resulting in the blast furnace overhaul and renovation project's working area is often very narrow, and sometimes even large equipment cannot enter the work area. During the hoisting process, it is required that the furnace shell cannot be deformed due to hoisting. For this reason, a special lifting tool ...
