The invention discloses a tower crane tower body steel structure health state detection method which comprises the following steps: (1) when a tower crane is installed, a tower crane deformation monitoring device is used for reading a geometric center point of a tower body base, and the geometric center point of the base is an original point of a space coordinate system; (2) arranging an antenna of the deformation monitoring device of the tower crane at a geometric center point of the top of a tower body of the tower crane; (3) collecting real-time space coordinates of the geometric center point of the top of the tower body through a deformation monitoring device of the tower crane; (4) calculating the horizontal distance S between the geometric center point of the top of the tower body of the tower crane and the geometric center point of the base of the tower body of the tower crane; and (5) the S is compared with a preset safety threshold value R, and whether the health state of the tower crane tower body steel structure is safe or not is judged. According to the method, the top of the tower body of the tower crane is monitored in real time, so that the running real-time health state of the steel structure of the tower body of the tower crane is monitored, and tower crane accidents caused by deformation and instability of the steel structure of the tower body of the tower crane are avoided.
