Installation method of indoor horizontal large flue in large sintering plant

Abstract

The invention provides a method for installing a large indoor horizontal flue in a large-scale sintering plant. 1) Preset bolt holes and hoisting holes for the concrete frame beam on the upper layer of the flue; 3) Install hoisting tools on the basis of the upper platform of the flue to install the monorail beam, and set the car gear, tow cable wire rope, tow cable pulley and corresponding accessories at both ends of the monorail beam I-beam; 4) Install the electric Hoist the hoist to the temporary platform; 5) Hoist the flue ash hopper to the temporary transfer platform with a crane, and then use an electric hoist to hoist the flue ash hopper to the floor at the corresponding installation location before the flue is installed. After the installation is in place, lift the ash hopper for installation; 6) Lift and install the flue sliding support and fixed support; 7) Install the large flue from the nose to the tail; 8) Confirm the installation on the installed flue position, the flue ash hopper is slowly pulled to the bottom of the flue, and the adjusted position is welded and fixed; 9) Remove the monorail beam and electric hoist.

Description

technical field [0001] The invention relates to a method for installing a large indoor horizontal flue in a large sintering plant. Background technique [0002] The indoor flue of a large-scale sintering plant has the characteristics of large diameter and thin pipe wall. It is installed in a concrete frame and has a small installation space. The method is to drag the short flue pipe to the installation position by making slide rails made of section steel and hoisting and dragging, and then use chain hoists and other tools to lift the short flue pipe into place. This method needs to be closed repeatedly. The hoisting wire rope is unwound, and the sliding and installation speed is slow and the efficiency is low. The hoisting mechanical installation method is to use the hoisting machine to hoist the short pipes of the flue on both sides of the factory building and assemble them in place in the frame. When the short pipe is hung from the outside to the frame, the flue support ...
