本项目主要针对国内焊接结构的410T及以上的电站锅炉的结构特点,打破以往吊装方法,变侧前开口为侧后开口,并改顶板组件部分次梁缓装,受热面大件吊装穿插于钢结构吊装过程中。本项目的实施,减少了大件的倒钩次数,增大了吊装过程的安全性,可靠性,使方案更加合理。本项目主要是结合了焊接结构与高强螺栓结构的钢结构特点,并将二者吊装方法即侧开口和顶开口有机的融合在一起,同时将受热面大件吊装穿插与钢结构吊装过程中。
This project mainly aims at the structural features of domestic power boilers with 410T and above in the domestic welded structure, breaking the previous lifting methods, changing the front opening to the side rear opening, and modifying the top plate assembly part of the secondary beam to slow down, and the large heating surface is suspended in the steel. Structure hoisting process. The implementation of this project reduces the number of large barbs, increases the safety and reliability of the lifting process, and makes the plan more reasonable. This project mainly combines the characteristics of steel structure with welded structure and high-strength bolt structure, and the two methods of lifting are organic integration of the side opening and the top opening, while the large heating surface is installed in the process of lifting and interfacing with steel structure lifting.
