The invention discloses a segmented vertical hanging device for tower sections. The segmented vertical hanging device comprises a guide rail arranged in the length direction of a first tower section,the two ends of the guide rail are flush with the two ends of the tower section, and the guide rail is fixed to one side of the first tower section. The segmented vertical hanging device further comprises a rod clamping pipe, the rod clamping pipe is arranged on the guide rail through a self locking and lifting slide clamp, a rod clamping head is horizontally arranged at the top of the rod clamping pipe, a fixed pulley is arranged on the rod clamping head, one end of a lifting rope penetrates through the bottom of the rod clamping pipe and fixed to the top of a second tower section after beingwound through the fixed pulley, and the other end of the lifting rope is connected to a force applying source. According to the segmented vertical hanging device, by arranging the guide rail on the first tower section, and arranging the slidable rod clamping pipe on the guide rail, and arranging the fixed pulley on the rod clamping pipe, the second tower section can be pulled above the first tower section, both time and labor are saved, the occupied area is small when the segmented vertical hanging device is used, and the mounting quality is good.
