The invention discloses an auxiliary device for mounting a tower crane and belongs to the technical field of crane mounting equipment. The auxiliary device comprises no less than one adjusting screw rod (9) and no less than two connecting bars, wherein the adjusting screw rods and the connecting bars work together to adjust the length of the auxiliary device and are alternately arranged and connected. The two ends of the auxiliary device are respectively connected with a balance arm and an upper support through the connecting bars. The adjusting screw rods and the connecting bar together form the auxiliary device; during installation of the tower crane, only one set of lifting equipment is needed to connect the balance arm and the upper support around a hinge point A, and at the moment, the two ends of the auxiliary device are respectively fixed to the balance arm and the upper support to form a stable triangular structure to ensure safer follow-up installation of a lifting beam; when a pin shaft mounted at a hinge point B is malposed, the adjusting screw rods and the connecting bars can work together to change the length of the auxiliary device to perform accurate positioning and adjusting, so that the mounting intensity is low and the operation is easier.
