The invention relates to a novel anti-unhooking device for a lifting hook, and belongs to the technical field of tower cranes. Comprising a lifting hook, a pin shaft, a pin, a lifting hook safety lock and an anti-unhooking device, the lifting hook safety lock is connected with the lifting hook through the pin shaft, and the anti-unhooking device is connected with the lifting hook and the lifting hook safety lock through the pin shaft; and the lifting hook safety lock and the anti-unhooking device are limited on the pin shaft through pins. A bolt, a bent plate, a gasket and a nut are also arranged on the lifting hook; and the bending plate is fixed on the anti-unhooking device through a bolt, a gasket and a nut on the two sides. The lifting hook safety lock has the beneficial effect that the anti-falling effect can still be achieved under the condition that the lifting hook safety lock fails. According to the anti-unhooking device for the lifting hook, the safety of the lifting hook in the lifting process is greatly improved, and the anti-unhooking device is simple and labor-saving to operate.
