Electric pole steel bar tensioning device

The utility model relates to the technical field of annular concrete electric pole production, in particular to an electric pole steel bar tensioning device. The electric pole steel bar tensioning device comprises an anchoring assembly, a plurality of stress sensor assemblies and a stress monitoring instrument. The two ends of the anchoring assembly are the anchoring end used for being connected with an electric pole mold and the tensioning end used for applying tensioning force correspondingly. A plurality of anchoring holes are formed in the anchoring end of the anchoring assembly, a plurality of prestressed steel bars penetrate through the anchoring holes in a one-to-one correspondence mode, and the stress sensor assemblies and the anchoring holes are arranged at the tensioning end in a one-to-one correspondence mode so as to be connected with the prestressed steel bars in a one-to-one correspondence mode and conduct tensioning stress measurement; the plurality of stress sensor assemblies are electrically
