Bridge pier column verticality detection device

The utility model provides a bridge pier column verticality detection device, and relates to the technical field of bridge construction. The bridge pier column perpendicularity detection device comprises a moving seat, the top of the moving seat is fixedly connected with a supporting seat, the top of the supporting seat is provided with a mounting frame, a connecting piece used for rotation is arranged between the mounting frame and the supporting seat, the top of the mounting frame is connected with a fixing frame, and a rack is slidably connected into the fixing frame. According to the bridge pier column perpendicularity detection device, the rotating frame is kept stable after rotating, and a connecting rope between the winding disc and the rotating shaft is unwound by rotating the winding disc, so that the rotating shaft rotates, a pull rope wound on the outer side of the rotating shaft is unwound under the gravity action of the gravity block, and the perpendicularity of the bridge pier column is detected
