| description | The present invention relates to an integrated and a split-type ultrasonic probe for measuring an axial force of a high-temperature bolt, the integrated ultrasonic probe being vertically installed, and the split-type ultrasonic probe being installed in a bent manner. The integrated ultrasonic probe for measuring an axial force of a high-temperature bolt can respectively excite and receive an SH0 wave and an A0 wave, and the split-type ultrasonic probe for measuring an axial force of a high-temperature bolt comprises an SH0 probe that excites and receives the SH0 wave and an A0 probe that excites and receives the A0 wave, wherein the two probes are used cooperatively. By means of the present invention, on the basis of the characteristics of the concentration of acoustic energy in the center of a bolt when the SH0 wave and the A0 wave propagate, and the wave velocity variation of the SH0 wave and the A0 wave when the axial force of the bolt changes, a waveguide rod is introduced to serve as a propagation medium between the high-temperature bolt and an ultrasonic transducer that is easily influenced by temperature, so as to ensure that the ultrasonic transducer can stably work in a comfortable environment for a long period of time to achieve the purpose of measuring the axial force of the bolt in a high-temperature environment. |
