The invention discloses a steering knuckle structure for a tower crane. The steering knuckle structure comprises a steering support, a left flange plate and a right flange plate, wherein the left flange plate and the right flange plate are of an integral structure and arranged on two sides of the steering support, a left pin shaft and a right pin shaft are respectively inserted and mounted on theleft flange plate and the right flange plate, a steering knuckle rod is arranged between the left flange plate and the right flange plate, and a left circular table connecting section and a right circular table connecting section are respectively and rotatably inserted into circular table inserting grooves symmetrically arranged at the two sides of the tail end of the steering knuckle rod; a leftcylindrical tail section and a right cylindrical tail section are respectively and rotatably inserted into cylindrical inserting grooves arranged at the middle positions of the tail ends of pin shaftholes, a plurality of square inserting grooves are uniformly distributed on the left cylindrical tail section, the right cylindrical tail section is provided with a plurality of square inserting columns of an integrated structure, and the plurality of uniformly distributed square inserting columns are arranged in the plurality of uniformly distributed square inserting grooves in an inserting and assembling manner. By adopting the steering knuckle structure, the mounting and dismounting between the steering support and the steering knuckle on the tower crane can be conveniently realized, and the connection reliability and the loading and unloading efficiency are improved.
