Track-type heightening frame device for heightening construction of pier body steel bars and heightening method of track-type heightening device

The invention discloses a track-type heightening frame device for heightening construction of pier body steel bars and a heightening method of the track-type heightening frame device. The problems that in the prior art, high-pier steel bars cannot move directionally in space, during heightening construction, lengthening is difficult, workers are fatigable, the efficiency is low, and safety is loware solved. The track-type heightening frame device comprises a base, supporting frames, an I-shaped traveling track, electric hoists, connectors, steel bar parts and sleeves. The heightening method mainly comprises the steps that the track-type heightening frame device is designed and manufactured firstly and then mounted, then the steel bars are moved in the vertical direction and then moved inthe horizontal direction, then the to-be-heightened steel bars are mounted in a heightening mode, and after all the steel bars at the same working section of a pier body are heightened according to the method, the track-type h
