The utility model discloses a welding tool for boiler eccentric furnace gallbladder, which comprises a sleeve sleeved on the furnace gallbladder. The sleeve is provided with a bracket extending to the inside of the tube chamber, the suspension end of the bracket is connected with the furnace gallbladder, the furnace gallbladder and the sleeve are eccentrically arranged, and the sleeve and the combustion chamber tube are arranged in the same core. The utility model provides a sleeve for eccentrically fixing the furnace gallbladder with a sleeve, and the eccentric direction and eccentricity are kept in accordance with the eccentric direction and eccentricity between the furnace gallbladder and the reburning chamber, which ensures the arrangement of the sleeve and the core of the reburning chamber, so that under the action of the roller support driving mechanism, the sleeve, the furnace gallbladder, the front and the rear can be guaranteed. During the synchronous rotation of the tube sheet and the cylinder of the combustion chamber, the position relationship between the front tube sheet and the cylinder of the combustion chamber is stable, which provides a reliable and stable maintenance relationship for the welding between the two, and the welding quality between the two can be guaranteed.

锅炉偏心炉胆的焊接工装
本技术涉及焊接工装,具体讲就是锅炉偏心炉胆焊接的辅助工装。
技术介绍
现有技术中,锅炉的炉胆和壳体为两个筒管状的部件,成型后两者之间的位置关系为筒芯轴向平行的、间隔布置关系,即所谓的锅炉壳体与炉胆之间为偏心设置的关系,实际上首先就是回燃室与锅炉壳体两者为管芯平行、间距的偏心布置,同时回燃室与炉胆同样采用管芯平行、间距的偏心布置。回燃室包括两端的回燃室的前、后管板1、2,而炉胆4的一端与前管板1焊接,且两者之间为偏心布置即前管板1上有相对于圆形管板中心偏心开设的孔口与炉胆4的一端焊接相连,再将两端的前、后管板1、2与回燃室筒体3焊接由此构成炉胆相对于回燃室的偏心布置关系,后管板2和焊接有炉胆的前管板1再与回燃室筒体3焊接构成回燃室初段总成,该初段总成还要与壳体、烟管类管件等焊接。后管板2、焊接有炉胆的前管板1与回燃室筒体3之间的焊接一般采用埋弧焊工艺,即需要工件转动,焊枪处于平焊位置。对于上述的WNS型锅炉内胆偏心结构的构件之间的焊接,难以实现焊接有波形内胆4的前管板1、后管板2连同回燃室筒体3一起作同步转动,并且内胆由于自重而施加于前管板1 ...
