Abstract
The utility model discloses a lifting hook deformation monitoring device. The monitoring device comprises a resistor strain foil which is bonded and fixed on a lifting hook so as to monitor the deformation of a lifting hook, wherein the resistor strain foil is provided with a signal output terminal for outputting a resistivity change signal according to the deformation amplitude of the lifting hook. The monitoring device further comprises a signal processor which is used for receiving and processing the resistivity change signal so as to obtain the deformation amplitude of the lifting hook, wherein the signal processor is provided with a signal input terminal connected with the signal output terminal of the resistor strain foil in a signal sampling manner. When the lifting hook deforms under the action of stress, the compression deformation of the resistor strain foil bonded on the lifting hook is generated correspondingly, so that the resistivity of the resistor strain foil is changed; the signal processor is used for receiving and processing the resistivity change signal, so that the deformation amplitude of the lifting hook is obtained. Thus, the lifting hook is overhauled, maintained or replaced by an operator according to the deformation amplitude of the lifting hook. As a result, the accident of heavy article falling due to the large deformation of the lifting hook is avoided.
