Description

Vertical coiled plate construction mechanism of thin-wall vertical storage tank and construction method thereof Technical Field The invention relates to the technical field of vertical storage tank construction, in particular to a vertical coiled plate construction mechanism of a thin-wall vertical storage tank and a construction method thereof. Background The vertical storage tank is one of core equipment in the chemical industry field, is widely applied to various industries such as food and beverage, light industry, organic chemistry and the like, and is usually manufactured and installed on site at a use place so as to meet storage requirements in different scenes. In the field construction of the thin-wall vertical storage tank, the rolling and mounting quality of the wall plate directly determine the overall performance and the service life of the storage tank. In view of the above-mentioned related art, in practical application, the existing construction process generally adopts a horizontal plate bending machine to roll the storage tank wall plate, and after the rolling is completed, the wall plate is stacked and stored on the bracket. However, as the actual use direction of the vertical storage tank wallboard is vertical, the stacked wallboard needs to be lifted by a crane and turned over by 90 degrees during installation, and then the stacked wallboard is transferred to a tank wall installation position for welding operation. The process has the obvious defects that the horizontal plate bending machine has large occupied area and high requirements on site construction sites, and the crane needs to be put into use for a long time, so that the construction cost is increased, and the construction efficiency is reduced. In addition, for thin-wall vertical storage tanks, the easy deformation of the wall plates is a prominent problem in the construction process. In the process of rolling, curvature deviation of the wallboard is easy to generate due to self gravity, plastic deformation of the wallboard is easy to generate due to external force action in the transferring links of stacking, overturning, lifting and the like, meanwhile, the molding precision of the wallboard is further affected due to improper process in the welding and installing process, finally, the sealing performance of the storage tank is reduced, the structural stability is insufficient, the service life of the storage tank is shortened, and the later maintenance cost is increased. Therefore, there is a need for a construction mechanism and a construction method that can solve the above-described technical pain points.
