The invention discloses a tower crane self-locking hydraulic attachment device which comprises a core tube, a plurality of holes are formed in the side wall of the core tube, a plurality of supporting beam components are fixedly connected between the inner side walls of the core tube, each supporting beam component comprises two main beams, a plurality of anti-torsion beams are fixedly connected between the two main beams, and the anti-torsion beams are fixedly connected between the two main beams. The tops of the two main beams are fixedly connected with two I-shaped beams, the side walls of the two I-shaped beams are fixedly connected with C-shaped frames, the C-shaped frames and the I-shaped beams jointly define a rectangular groove used for fixing the tower crane, the two ends of each main beam are provided with telescopic brackets, the side walls of the main beams are fixedly connected with anti-extrusion reinforcing ribs, and the telescopic brackets are fixedly connected with the anti-extrusion reinforcing ribs. And one end of the anti-extrusion reinforcing rib is fixedly connected with an anti-bending truss. The functions of oil cylinder pressure control, pressure detection, elongation and shortening and the like are achieved, the phenomenon of'force loss' is avoided through mechanical self-locking of the lead screw, the structure is safer and more reliable, shear force can be resisted through the structure, and the applicability is higher.
