Large-scale container equipment rotation method realized by adopting large-scale container equipment rotary platform

Abstract

A large-scale container equipment rotation method realized by using a large-scale container equipment rotary platform. The rotary platform includes: a turntable, a turntable base, and a slewing support respectively connecting the turntable and the turntable base. The slewing support realizes the relative rotation between the turntable and the turntable base. A roller frame is installed at one end of the large container equipment, and a roller frame is also installed on the turntable of the large container equipment slewing platform, and the two ends of the large container equipment are respectively lifted by the crane, and the end of the large container equipment without the roller frame is placed and fixed Go to the roller frame on the large container equipment rotary platform, start driving to pull one end of the large container equipment installed with the roller frame, and the large container equipment rotary platform will rotate accordingly, with the end of the large container equipment not equipped with the roller frame as the center of the circle. to rotate. The invention has the advantages of simple structure, easy construction and disassembly, strong operability, low manufacturing cost, strong structural versatility and good economic benefits.

Description

technical field [0001] The invention relates to nuclear power technology, in particular to a large-scale container equipment rotation method realized by a large-scale container equipment rotary platform. Background technique [0002] In the manufacturing process of a large steam generator, after the final circumferential seam welding is completed, it needs to enter the filming room for RT flaw detection. During the process of entering the filming room, the steam generator needs to be rotated 90°. Such as figure 1 As shown, the steam generator b has a total length of about 23.7m and a weight of about 813 tons. Due to the limitation of the factory building and the structure of the train, this rotation process cannot be completed. When the distance D between the two trains a is the smallest, the steam generator still has a certain The angle of rotation cannot be completed by driving alone. The industry usually uses hanging beams to complete the station rotation of such large ...

AI Technical Summary

Problems solved by technology

like figure 1 As shown, the steam generator b has a total length of about 23.7m and a weight of about 813 tons. Due to the limitation of the factory building and the structure of the train, this rotation process cannot be completed. When the distance D between the two trains a is the smallest, the steam generator still has a certain angle, the rotation cannot be completed by driving alone

The industry usually uses hanging beams to complete the station rotation of such large container equipment, but the cost of purchasing a hanging beam that can meet such a large load requirement is very high
