Problems solved by technology

[0004] For such a huge equipment, it is very difficult to dismantle and construct it. There is no domestic and international project that protects and dismantles a large and towering steel structure facility similar to the main tower, and then transports it thousands of kilometers away for reuse and installation. example

Abstract

The invention relates to the field of hoisting and hauling operations and especially relates to a protective dismantle and assembly method for large-scale towering steel structures. The protective dismantle and assembly method for large-scale towering steel structures is characterized by following steps which are carried out sequentially: A. dismantling segment by segment; B. marking by drawing lines; C. numbering; D. lifting lug assembling; E. operating by two combined operation modes; F. pre-hoisting; G. cutting segment by segment; H. combined dismantling piece by piece; I. dismantling integrally. The operation by the invention is safe and reliable and the device utilization rate is high.

Description

technical field [0001] The invention relates to the field of lifting and pulling operations, in particular to a method for protective removal and installation of large towering steel structures. Background technique [0002] COREX is the abbreviation of CoalReductionExtreme. The literal translation is "directly using coal to make iron as the ultimate goal." COREX is a smelting reduction ironmaking process that uses lump ore or pellets as raw materials and non-coking coal as reducing agent and fuel. [0003] COREX furnaces generally occupy a large area, are heavy in weight and high in height. Taking the C3000 type COREX furnace as an example, the main tower is as follows: figure 1 As shown, it is a large towering steel structure with a height of 118m and a layout size of 49m×19m. Figure 2-4 As shown, the weight is more than 10,000 tons; Figure 5 As shown, the maximum cross-section of box-type frame column is 2400×1600×80×80mm, the maximum cross-section of box-type frame b...
