Drag link mounting device and drag link mounting method applied to tower crane

The embodiment of the invention discloses a drag link mounting device applied to a tower crane. The drag link mounting device comprises a pulling plate and a stop block, wherein one end of the pulling plate is provided with a pin hole; the pin hole is connected with the tower top through a pulling plate pin shaft; the other end of the pulling plate is provided with a notch; an opening of the notch faces upwards; a drag link pin shaft slides into the notch from the opening of the notch; the stop block stops the drag link pin shaft in the notch to prevent the drag link pin shaft from loosening from the notch. The embodiment of the invention also discloses a method for mounting a drag link of the tower crane by using the drag link mounting device. When the drag link is connected and arranged between a boom (or balance arm) and the tower top, the pin shaft is not required to be driven in the air, and the drag link pin shaft slides into the notch of the pulling plate; the mounting method is easy to operate, the drag link can be quickly mounted, the drag link mounting time is shortened, the drag link mounting difficulty is reduced, the mounting efficiency is improved, and the mounting cost is saved.
