The invention discloses a tower crane wind force compensation device comprising a tower body and a compensation unit. A rotary center is arranged on the upper portion of the tower body. The compensation unit comprises a rotary assembly and a torsion spring. The upper end and the lower end of the rotary assembly are in matched connection with the rotary center. The torsion spring is arranged in therotary center in a wound mode, and the two ends of the torsion spring are connected with the symmetrical positions of the rotary assembly. The rotary assembly comprises a rotary installing ring, a blade arranged on the rotary installing ring, and a counterweight assembly arranged on the rotary installing ring, and the position of the counterweight assembly corresponds to that of the blade. The counterweight assembly comprises a counterweight bar and a counterweight block arranged at one end of the counterweight bar. Through the tower crane wind force compensation device, the problems that instrong wind or typhoon weather, wind force applied to a tower crane is large and is bad for stability of the tower crane, and if the wind force is too large, the tower crane may even be inclined or beblown down are solved, then service life of the tower crane is prolonged, and simple and effective effects are achieved.
