Abstract

The invention provides a mounting method for the top of a large gas holder of a steel mill. The method comprises the following steps that Step 1, a lifted structure is assembled in an inner wall areaof a gas holder side plate, and a lifter is mounted at the top of a stand column; Step 2, the lifted structure is integrally lifted by a preset distance, then is suspended and stands for a preset time; the steel structure of the lifted structure and temporary lifting facilities are comprehensively inspected; Step 3, lifting is continued, each lifting point accurately reaches a preset position through a hydraulic synchronous control system, related data are measured again, and a hydraulic lifter is locked; and Step 4, connection of the cabinet top and the side plate is completed, and then graded unloading is performed on the hydraulic lifter. According to the method, an integral hoisting mode is adopted, the steel structure at the top of the gas holder is firstly assembled on the ground, and then integral hoisting is carried out through hydraulic synchronous lifting of ultra-large components, so that the high-altitude hoisting workload is reduced to the greatest extent, the mounting andconstruction period is shortened, the construction efficiency is improved, and the construction quality and safety are ensured.

Description

technical field [0001] The invention relates to the technical field of blast furnace gas cabinets, in particular to a method for installing the top of a large gas cabinet in a steel plant. Background technique [0002] At present, the construction of the top of the conventional blast furnace gas cabinet adopts the method of high-altitude hoisting in parts, which not only requires a huge amount of high-altitude assembly and welding, but also has great quality and safety risks, making the overall construction more difficult. Contents of the invention [0003] In view of this, the present invention proposes a method for installing the top of a large gas tank in a steel plant, aiming at reducing the construction difficulty of the top of a blast furnace gas tank and improving construction efficiency. [0004] In one aspect, the present invention proposes a method for installing the top of a large gas tank in a steel plant, including: [0005] Step 1: Assemble the lifted struct...
