Embodiment Construction
[0032] In order to make the present invention more clearly understood, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0033] refer to figure 1 , figure 2 , image 3 , Figure 4 , the construction method of the simultaneous hoisting of the double cabinet top beam of the present invention comprises the following steps:
[0034] (1) First, according to the distance between the two cabinet top beams 1 on the gas cabinet, the cabinet top platform 2 is set up on the gas cabinet piston plate, and the cabinet top platform 2 is welded by the angle steel of model L50*6. The components include a crossbeam 21 and two support legs 22 arranged at the bottom of the crossbeam 21, and the bottom of the support legs 22 is a model L30*3 angle steel as a diagonal brace 3 (see figure 1 , figure 2 ), the other end of the diagonal brace 3 is fixed with the gas tank piston plate by spot...

The invention discloses a construction method for hoisting double rows of tank top beams synchronously. The method comprises the following steps of setting up a tank top rack on a gas tank piston plate, welding two baffles at the upper part of a cross beam of the tank top rack, hoisting two bent tank top beams into the gas tank and making them arranged on the tank top rack; welding vertical angle steels and cable-stayed angle steels between two tank top beams; hoisting two tank top beams synchronously and welding the two tank top beams in place. The construction method for hoisting double rows of the tank top beams synchronously provided by the invention solves many problems in the prior art, and the advantages are as follows: double rows of the tank top beams can be supported synchronously, thus the disadvantages in the prior that the measuring is difficult when installing the tank top beam and the installation personnel in place is difficult can be overcome, and the defect in the prior art that the tank top beam is easily skewed in the installation process can be successfully avoided; besides, tedious labor due to the fact that in the existing single-tank top beam installation manner that double rows of the tank top beams need to be repaired again due to the inconsistent intervals between the installed double rows of the tank top beams can also be avoided, thus the construction time is saved, the construction efficiency is improved and the appearance quality of the overall project is also guaranteed.
Description
technical field [0001] The invention relates to the metallurgical industry, more specifically, the invention relates to a construction method for simultaneously hoisting double cabinet top beams in the metallurgical industry. Background technique [0002] In recent years, there have been more and more modern large-scale converter steelmaking plants, and their supporting gas recovery devices - rubber membrane sealed gas cabinets have also increased accordingly. [0003] Those skilled in the art know that the rubber membrane sealed gas tank belongs to a thin-walled pressure vessel, and its top is an arc-shaped spherical surface welded and installed by many criss-cross arc-shaped angle steel beams. Therefore, the top of the cabinet There are certain difficulties in the installation and construction of the beam. [0004] In the installation and construction of the existing cabinet top beam, since only one cabinet top beam can be installed at a time, the setting-out must be meas...
