Description

Technical Field

[0001] The utility model relates to the technical field of bolt axial force monitoring, in particular to an ultrasonic longitudinal wave bolt axial force monitoring device. Background Art

[0002] High-strength bolts are widely used in various industries. These bolts can cope with pressure, vibration and impact in the environment. In general, bolt structures are used to connect and fix key components and play an important role in many industries. During the installation of high-strength bolts, improper control of the bolt axial force often causes bolt failure. In short, excessive or insufficient bolt axial force will cause uneven force on the structure and affect the reliability and safety of the equipment. Accurate monitoring of the bolt axial force can effectively avoid the problem of bolts being too loose or too tight.

[0003] After searching, the patent number "CN116858415A" mentioned in the text that "the utility model discloses a real-time monitoring method for the axial force when tightening high-strength bolts. The method is based on the propagation characteristics of sound waves in materials. By accurately measuring the change value of the screw state quantity in real time, the real-time axial force value of the bolt is obtained by the reverse method. The axial force change trend is associated with the bolt tightening operation, and the execution of the operation process is accurately guided to achieve precise control of the axial force of high-strength bolt tightening, so that each bolt in the structure is evenly stressed, and effectively avoids the occurrence of bolt failure due to improper control of the bolt axial force, thereby improving the reliability and safety of the equipment." When in use, the bolt axial force is monitored by a dual-wave ultrasonic probe to prevent the bolt from being too loose or too tight. However, the monitoring device requires manual monitoring of the bolts one by one. Since each step requires manual participation, it usually takes more time and manpower, which increases the workload of the operator and reduces the efficiency of bolt axial force monitoring.
