The invention provides a tower crane lifting device, and relates to the technical field of engineering machinery. The tower crane lifting device comprises a base, a sliding limiting mechanism is fixedly connected to the top of the base, a lifting joint is slidably connected to the center of the sliding limiting mechanism, and a lifting jacking mechanism corresponding to the lifting joint is arranged in the center of the base. A plurality of fixed-point locking mechanisms corresponding to the lifting joint are installed on the outer side of the sliding limiting mechanism, and the bottom of one side of the sliding limiting mechanism is fixedly connected with a sliding guide mechanism corresponding to the lifting joint. A mounting groove corresponding to the lifting jacking mechanism is formed in the center of the base. Through the sliding limiting mechanism, the lifting jacking mechanism, the fixed-point locking mechanism and the sliding guide mechanism which are simple in design, a standard knot can be quickly assembled and fixed at the bottom of a tower crane, operation is convenient, meanwhile, no large construction risk exists, and the device is worthy of vigorous popularization.
