When the steel Containment Vessel (CV) end plate of the AP1000 nuclear power station is constructed, a large number of accessories are required to be welded on the inner side and the outer side of the end plate, and in order to ensure the welding quality, flat position welding is adopted; therefore, the end closure plate needs to be turned over for construction. The single nuclear island needs to turn over the end enclosure plate for 64 pieces, and the maximum weight of a single piece is 12t; the unique double curvature structure of the end closure plate requires strict control of deformation during the overturning process.
At present, the conventional method is double-crane lifting, namely, two cranes are used for matching to finish the overturning operation of the end enclosure plate, and the defect is that:
(1) The double-crane lifting requires that the two cranes are tightly matched, the number of the end closure plates is large, the weight is large, the frequent overturning and lifting operations are carried out, and the potential safety hazard is large;
(2) In the process of turning the end enclosure plate, the end enclosure plate needs to be turned 180 degrees, and the double-machine lifting and hanging process needs to be repeatedly unhooked and hooked for a plurality of times, so that the construction steps are more and the efficiency is lower;
(3) Because the weight of a single piece is large and can reach 12t, the position of the single piece needs to be manually adjusted in the lifting operation process, so that the operation is inconvenient;
(4) Because only two hanging points exist, stress concentration is easy to generate in the hanging process, so that the local deformation of the hanging points is caused, the double-curvature structure is influenced, and the integral structure of the equipment is further influenced;
(4) The turnover times are more, and the work cost of the crane is too high.
