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 large tank installing method. The large tank installing method comprises the installing steps that at least two winches are arranged on an uppermost-layer workshop platformthrough which a to-be-installed tank is about to penetrate, and the winches are symmetrically arranged on the two sides of a to-be-installed position of the tank; then, traction ropes of the winches penetrate through stress points and then are downwards released to arrive at the ground; the to-be-installed tank is segmented from top to bottom to be hoisted; a hoisting lug is welded to each of thetwo side walls of a first-section tank body located at the top end, a tackle is used for fixing a section of steel wire rope to the corresponding hoisting lug, then, the steel wire rope is connected with the traction ropes of the winches, and hoisting is started; and after each section of tank body is hoisted, the opposite opening positions of every two adjacent sections of tank bodies are welded.An existing platform in a workshop is utilized for installing work, the advantages that hoisting work can be conducted without usage of a crane, the occupied field area is small, production is not influenced, operation difficulty is low, and the safety coefficient is high are achieved, and the large tank installing method is worthy of being popularized and applied to metallurgy 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...
