The invention relates to the technical field of tower crane safety facilities, and particularly discloses a tower crane anti-climbing device which comprises a door plate and further comprises three first anti-climbing units, a second anti-climbing unit and a plurality of steel wire ropes. The first anti-climbing unit comprises a first bottom plate, a first hinge plate and a first blocking rod. The lower end of the first hinge plate is hinged to the lower end of the front face of the first bottom plate. The second anti-climbing unit comprises a second bottom plate, a second hinge plate and two second blocking rods. The lower end of the second hinge plate is hinged to the lower end of the front face of the second bottom plate. The first hinged plates of every two adjacent first anti-climbing units are connected through steel wire ropes, and the first hinged plates of the first anti-climbing units and the second hinged plates of the second anti-climbing units are connected through steel wire ropes. Compared with the prior art, operation is easy and fast during installation, and on-site cutting and welding, frame erecting of steel pipes one by one and other operation are not needed. And after being disassembled, the storage and transportation are convenient, the occupied space is reduced, the device can be reused, and resources are saved.
