[0029] As shown in the figure, Figures 1-3 The present embodiment provides a boiler pipe hanging special tool for power plant, which comprises a fixed pulley 1 suspended on a steel wire rope as a track, the fixed pulley 1 is erected on a pedestal 2, the pedestal 2 is movably connected with a lifting lug 3, and pulling the lifting lug 3 can make the lifting lug 3 rotate relative to the pedestal 2.

[0030] In the present embodiment, as shown in the figure, Figure 1 and Figure 2 The pedestal 2 comprises a bottom plate 21 and two vertical plates 22 for erecting the fixed pulley 1, the vertical plates 22 are fixedly connected to the upper end face of the bottom plate 21, and the fixed pulley 1 is rotatably connected between the two vertical plates 22.

[0031] In the pedestal 2, a plurality of first through holes 211 are formed in the bottom plate 21 for connecting adjacent pedestals 2. A second through hole 212 is formed in the center of the bottom plate 21, the lifting lug 3 penetrates through the second through hole 212 and can rotate in the second through hole 212.

[0032] Specifically, the bottom plate 21 is provided with four first through holes 211, and each first through hole 211 is located at the periphery of the second through hole 212, i.e. the four first through holes 211 are located at the four side sides of the second through hole 212.
