Upper smoke hood hoisting method based on BIM technology

Abstract

The invention provides an upper smoke hood hoisting method based on a BIM technology. The method comprises the following steps that (1) all span steel structures and devices are subjected to 1:1 three-dimensional modeling through BIM software according to drawing sizes of all the span steel structures and the devices; (2) three-dimensional models are assembled, specifically, the three-dimensional models of all the span steel structures and the devices are effectively assembled according to the field and process assembling drawing requirements, and the effect that the assembled models of the span steel structures and the devices are consistent with field assembled bodies is ensured; (3) the sizes of the assembled models are rechecked; (4) hoisting is simulated; (5) a hoisting channel is detected; and (6) a hoisting scheme is determined, specifically, after the situation that the hoisting channel is unblocked is ensured, the whole-process hoisting scheme is generated through a computer and saved to a video format file. Through the method, unnecessary device and steel structure dismounting workload can be reduced, the device down time is reduced, the safety coefficient of the hoisting process and field construction efficiency are improved, and influences of upper smoke hood hoisting to other converter production time are reduced.

Description

technical field [0001] The invention relates to equipment maintenance, in particular to a method for hoisting an upper fume hood based on BIM technology. Background technique [0002] The upper hood of the large-scale converter is located on the platform on the third floor of the converter span in the steelmaking area. The upper hood is large and heavy, while the span of the converter span is relatively small, and equipment or steel structure platforms are installed on all planes between the spans. The space is relatively narrow, and the narrow space across the converter directly affects the hoisting channel of the upper fume hood. When the upper fume hood needs to be replaced, the equipment and steel structures on the hoisting channel must be removed, which will also affect the normal production rhythm of other converters. However, whether the dismantling equipment and steel structure are reasonable will seriously affect the production rhythm, and if there are too many dis...

Problems solved by technology

[0003] However, due to years of flue gas and internal circulating water erosion, the upper hood wall will become thinner and the failure rate will gradually increase. Therefore, it is necessary to formulate an effective upper hood The hoisting plan and the dismantling plan of other equipment should not only ensure the smoothness of the hoisting passage of the upper fume hood, but also ensure that the impact time on the rest of the converters is minimized
