Hoisting method of super high equipment in factory building

Abstract

The invention discloses a method for hoisting ultrahigh equipment in a workshop. The method adopts electric hoist monorail cranes and is characterized by comprising 1, calculating strength of a workshop roof structure and an electric hoist monorail-crane rail, and carrying out bolting-welding connection of a workshop roof beam and the electric hoist monorail-crane rail, 2, installing the four electric hoist monorail cranes at the bottom of the workshop roof beam, and 3, arranging the electric hoist monorail cranes in a way that the electric hoist monorail cranes are perpendicular to two process center lines on the workshop ground so that equipment in the two process center lines is in a hoisting range of the four electric hoist monorail cranes. The method realizes vertical and horizontal transport of various devices and members to installation positions, is convenient for hoisting, greatly improves an installation rate, and greatly reduces a construction cost.

Description

technical field [0001] The invention relates to a hoisting method, in particular to a hoisting method for ultra-high equipment in a factory building. Background technique [0002] The installation of ultra-high equipment in the workshop generally uses large lifting equipment, such as large mobile cranes (such as: truck cranes, crawler cranes) or large winches for hoisting, but in the metallurgical industry, especially during the installation of cold rolling line equipment, Due to the consideration of reducing the project footprint as much as possible, most of the equipment is arranged in the vertical space as much as possible. During the construction process, it is inevitable to encounter super-high equipment hoisting. However, especially when the construction period is tight, the hoisting after the plant is closed, and there is no hoisting equipment under the super high-altitude process structure in the plant, it is desired to hoist the alloy tower process structure to a he...

AI Technical Summary

Problems solved by technology

However, especially when the construction period is tight, the hoisting after the plant is closed, and there is no hoisting equipment under the super high-altitude process structure in the plant, it is desired to hoist the alloy tower process structure to a height of 74 meters, with a total weight of more than 700 tons of equipment and a weight of 2,000 tons Process steel structure, in which the largest single piece of equipment weighs 9 tons. Getting to the predetermined process installation position has become a difficult problem in the hoisting of heavy equipment in the workshop
