The invention discloses a jacking oil cylinder adjusting device for a tower crane, and belongs to the technical field of tower cranes. The device comprises a stop block fixed to a climbing frame, a rotary disc is installed on one side of the stop block, a screw rod is inserted into the middle of the rotary disc in a penetrating mode, the screw rod is in threaded fit with an axial threaded hole inthe middle of the rotary disc to form a spiral feeding mechanism, and the screw rod penetrates through the stop block and is in sliding fit with a through hole in the stop block, and one end, penetrating through the stop block, of the screw rod is hinged with a clamp for clamping the jacking oil cylinder; lug plates are longitudinal lug plates, and the through holes in the lug plates are longitudinal long holes; and the through hole in the stop block is a transverse long hole. According to the jacking oil cylinder adjusting device, swing adjustment of the jacking oil cylinder is achieved in alow-cost, simple and convenient mode, fine adjustment can be achieved, and lateral force is not generated to the oil cylinder when the jacking oil cylinder works.
