Description
Technical field
The present invention relates to diffusing tower installing area, specifically steel-making diffusing tower installation construction in a kind of narrow regions.
Background technology
When existing diffusing tower is installed, supervisor is an entirety, then install as stair, platform and igniter on supervisor, then the integral hoisting of diffusing tower is carried out, the mounting method of this diffusing tower, when installing stair, platform and igniter, the bracing frame of one is needed below diffusing tower, this bracing frame needs to spend a large amount of costs, and have very large lifting requirement to hoisting machine, particularly when narrow regions, the width in this region is difficult to hold whole supervisor sometimes, causes diffusing tower installation difficulty greatly to increase.
Summary of the invention
The object of the invention is to the shortcoming and defect overcoming above-mentioned prior art, provide in a kind of narrow regions and make steel diffusing tower installation construction, solve the defect that the cost that current diffusing tower integral installation has is high, require height to loop wheel machine lifting, can not use in narrow regions.
Object of the present invention is achieved through the following technical solutions: steel-making diffusing tower installation construction in narrow regions, described diffusing tower comprises the supervisor that is positioned at center and in the shape of a spiral around the spiral stairs of supervisor, the top of described supervisor arranges observation platform and igniter, and the installation method of this diffusing tower comprises the following steps:
A, supervisor point is cut into hypomere is in charge of, stage casing is in charge of and is in charge of with epimere, be transported to infield, be all that flat condition is positioned on the ground, be in charge of at hypomere, stage casing be in charge of when being in charge of in diffusing tower with epimere towards on one end, the position of distance termination 1 ~ 1.5m all welding operation platform respectively;
B, crane lifting hypomere are in charge of, be in charge of by hypomere and vertically lay, then location is fixing, namely the operating platform that hypomere is in charge of is positioned at upper end, then the spiral stairs that hypomere is in charge of is lifted, spiral stairs is in charge of around hypomere, extends upwardly to the position of the operating platform that hypomere is in charge of from the bottom spiral that hypomere is in charge of;
C, crane lifting stage casing are in charge of, and are in charge of in stage casing and divide pipe end to dock with hypomere, and staff climbs on operating platform along the mounted spiral stairs of step B, carry out stage casing be in charge of and hypomere be in charge of between welding;
D, welded after stage casing is in charge of and is in charge of with hypomere, namely on stage casing is in charge of, lift spiral stairs, spiral stairs is in charge of around stage casing, and the bottom spiral be in charge of from stage casing extends upwardly to the position of the operating platform that stage casing is in charge of;
E, crane lifting epimere are in charge of, and are in charge of by epimere and divide pipe end to dock with stage casing, and staff climbs to along spiral stairs mounted in step B and step D on the operating platform be in charge of in stage casing, carry out stage casing be in charge of and epimere be in charge of between welding;
F, crane lifting igniter, the operating platform that staff is in charge of at epimere carries out the installation of igniter;
G, disassemble stage casing and be in charge of the operating platform be in charge of with hypomere, leave operating platform that epimere is in charge of as observation platform.
In the present invention, supervisor is divided into three sections, lifts respectively, reduce the lifting requirement to crane, be in charge of 1-1.5m place below link position at three sections, setting operation platform, facilitate staff and carry out three welding be in charge of, and operating platform has just carried out welded and installed when below keeps flat being in charge of, easily, also only carry out the welded and installed of this operating platform, other be install on follow-up, do not need large-scale bracing frame, decrease cost.
Further, above-mentioned operating platform comprises around the shelf be responsible for and the flat board installed on the top of the shelf, and shelf is welded on supervisor.This operating platform structure is simple, easy installing/dismounting.
Further, the hypomere that in above-mentioned steps A, supervisor point is cut into is in charge of, stage casing is in charge of and is in charge of with epimere, and wherein, hypomere is in charge of and is accounted for supervisor's 40% ~ 45%, and stage casing is in charge of and is accounted for supervisor's 28% ~ 32%, and epimere is in charge of and is accounted for supervisor's 25% ~ 28%.Along with hoisting height does not increase gradually, the lifting capacity of crane is more and more less, so the Design of length that three sections are in charge of is become different by the present invention, shortens successively from top to bottom, be combined into an overall supervisor, the heaviest hypomere of such lifting is in charge of because highly very low, realizes very well, then highly slightly high, but the stage casing that weight is slightly light is in charge of, be finally highly the highest, but the lightest epimere of weight is in charge of, and reduce further the lifting requirement to crane like this.
The invention has the beneficial effects as follows:
(1) supervisor of diffusing tower is divided into three sections to be in charge of, then lifts respectively, reduce the lifting requirement to crane, and the length of supervisor in a disguised form reduces, and diffusing tower can be installed in narrow regions;
The below setting operation platform of (2) three sections of link positions be in charge of, facilitates being welded and fixed between being in charge of.
