The invention provides a tower crane self-locking linkage table and relates to the field of tower crane control devices. The tower crane self-locking linkage table comprises a self-locking mechanism and a cam set. The self-locking mechanism comprises a fixing base, a large support sleeve, a small support sleeve and an inner rod. The inner rod is installed in a handle rod. The small support sleeve is fixed to the lower middle portion of the handle rod, the large support sleeve is fixed to a second transmission shaft through a vertical secondary shaft, and the small support sleeve is installed above the large support sleeve. The fixing base is installed on a lower bottom plate and vertically placed under the inner rod of the self-locking mechanism. The fixing base is provided with a self-locking hole. The cam set comprises a first cam and a second cam, the lower side of the first cam is provided with a concave point, the concave point on the lower side of the first cam is in face contact with a first wheel, the lower side of the second cam is provided with a convex point, and the convex point on the lower side of the second cam is in linear contact with a second wheel. By means of the linkage table, the problem of misoperation occurring in the control process of a tower crane and the problems that a gear is complex in structure and not easy to overhaul when being used for gear control are solved, and self-locking of the linkage table is achieved.
