Abstract

The invention provides a method for assisting in tapping and positioning of a five-way ball by utilizing a BIM technology. The method comprises the following steps: calculating and determining a gravity center position of a five-way ball body; determining all lowest points for installation of the five-way ball body; determining a mounting lifting point for aligning the position of the five-way ball body; determining the length and the pipe diameter of a five-way ball body supporting vertical pipe; aligning the position of the five-way ball body, and measuring and marking a cross central line and a vertical central azimuth line of tapping of a downtake pipe to obtain a five-way ball body with the aligned position and the tapped downtake pipe; measuring and marking the relative positions ofthe key control points of tapping of a riser to obtain a five-way ball body with the tapped riser; determining the horizontal distance and angle between the key point of a riser eduction tube and thecross center line and the vertical distance between the key point of the riser eduction tube and the lowest installation point of the five-way ball; and connecting the adjusted five-way ball body withthe riser eduction tube through a stiffening plate. The five-way ball is subjected to three-dimensional modeling through the BIM technology, and the tapping position of the five-way ball is accurately measured.

Description

technical field [0001] The invention relates to the technical field of five-way ball construction, in particular to a method for using BIM technology to assist the opening and positioning of five-way balls. Background technique [0002] In the past ten years, the production capacity of the national metallurgical industry has expanded rapidly, and there have been many new construction, renovation and expansion projects. Among these projects, there is no shortage of super-large blast furnace projects. A new connection method is adopted between the riser and downcomer of this super-large blast furnace, that is, the connection between the riser and the downcomer by using a five-way ball. The diameter of the five-way ball can reach 7m, and the installation center elevation is above 100m. The combination of the five-way ball, the riser and the downcomer is a key and difficult technology in the construction of the blast furnace crude gas system. The slight angle and position devia...
