Embodiment Construction

[0022] Such as figure 1 and figure 2 As shown, the present invention takes the installation of an evaporative cooler supporting a 300t converter in a steel plant as an example. The main function of the evaporative cooler is to control the temperature of the flue gas generated during converter smelting within a specified range, and then enter the electrostatic precipitator for final dust removal , which is in the shape of a tank, with a diameter of 6000mm and a total length of 36529mm, divided into the upper part of 19670mm and a wall thickness of 10mm; the lower part of 16859mm and a wall thickness of 12mm. Installed behind the flue 1 at the end of the converter, it is connected to the flue 1 at the end by using an expansion adjustment device (soft connection), and runs through multiple platforms 2 in the converter workshop as a whole. Since the converter workshop has been put into production, there is no crane station in the workshop, and the crane cannot be used for instal...

Abstract

The invention relates to a method for installing a large tank body. The installation step is to install hoists on the uppermost workshop platform through which the tank body to be installed will pass through. There are at least two hoist machines, which are symmetrically installed on both sides of the tank body to be installed. ; Then pass the traction rope of the winch through the point of stress and let the rope down until it reaches the ground; hoist the tank to be installed in sections from top to bottom: weld the two sides of the first section of the tank at the top One lifting lug, use rigging to fix a section of steel wire rope on the corresponding lifting lug, then connect the steel wire rope to the traction rope of the winch and start hoisting; after the hoisting of each tank body is completed, weld the adjacent two tank body counterparts . The present invention utilizes the existing platform in the workshop to carry out the installation operation, and has the advantages of not using a crane for lifting operations, occupying a small area of ​​the site, not affecting production, low operation difficulty, and high safety factor, and is worthy of popularization and application in metallurgical construction projects.

Description

technical field [0001] The invention relates to the technical field of large-scale equipment installation, in particular to a large-scale tank installation method. Background technique [0002] In the process of metallurgical construction, there are many installations of large tanks. The traditional installation method is to place the tanks on the side of the installation location, and select the appropriate crane for installation according to the weight of the tank, the installation height and the operating radius of the crane. , This installation method is suitable for the installation work that is in the process of construction, and the installation site is flat and open, and it is suitable to use a crane. [0003] However, during some installation operations, there are no good conditions for crane lifting. For example, maintenance projects and technical renovation projects are installed in production workshops that have been put into use, and there is a problem that conv...
