A steel structure weld flaw detection scanning mechanism
ActiveCN224286813UMeet the needs of flaw detectionImprove flaw detection efficiencyAnalysing solids using sonic/ultrasonic/infrasonic wavesWelding defectPhysics
This utility model discloses a steel structure weld flaw detection scanning mechanism, relating to the field of steel structure inspection technology. The weld flaw detection scanning mechanism includes a base and a flaw detector mounted on the base, as well as a lifting assembly, an angle control assembly, a lateral movement assembly, and a moving assembly. This utility model, through the lifting assembly and the probe fixed on the lifting platform, can perform flaw detection on welds at high positions, improving detection efficiency. Simultaneously, the angle control assembly allows for arbitrary control of the probe angle, thus meeting the flaw detection needs of non-linear welds and improving the comprehensiveness and accuracy of flaw detection. The device, through signal feedback from the flaw detector in the lateral movement assembly and in conjunction with a PLC controller, can stop the probe's detection movement in real time when a weld defect is detected, thereby achieving precise positioning of the welding defect and avoiding positional errors caused by human error during handheld inspection.

Ultrasonic flaw detection comparison sample shaft for hollow axle of rail transit vehicle
ActiveCN224095789UQuickly and accurately calibrate flaw detection sensitivityImprove flaw detection efficiencyAnalysing solids using sonic/ultrasonic/infrasonic wavesStructural engineeringMechanical engineering
The utility model discloses an ultrasonic flaw detection comparison sample shaft for a hollow axle of a rail transit vehicle, which comprises a shaft body which is sequentially provided with a shaft neck, an unloading groove, a wheel seat, a gear box seat and a shaft body; an inner hole is formed in the axis position of the shaft body in a penetrating mode. The transverse defect, the longitudinal defect and the inner hole circular ring defect on the axle body are not only used for verifying the ultrasonic flaw detection program of the hollow axle, but also can quickly and accurately calibrate the flaw detection sensitivity. Wherein the inner hole circular ring defect can effectively calibrate and compare the inner hole surface defect, and the transverse defect and the longitudinal defect can effectively calibrate and compare the axle surface defect, especially the calibration and comparison of the defect of the arc transition part of the axle. The contrast sample shaft can be suitable for ultrasonic flaw detection of hollow axles of different vehicle types such as standard motor train units and inter-city motor train units, and the flaw detection efficiency and the product quality are improved.

A wind power fan blade nondestructive testing instrument
This utility model discloses a non-destructive testing instrument for wind turbine blades, belonging to the technical field of wind turbine blade flaw detectors. Its key technical features include an assembly frame and a base. The assembly frame is threadedly connected to the bottom of the base, and a flaw detection mechanism is threadedly connected to the front side of the assembly frame. An auxiliary mechanism is threadedly connected to the inner wall of the flaw detection mechanism. The flaw detection mechanism includes a mounting ring, a mounting groove, several infrared thermal imagers, several eddy current probes, several ultrasonic probes, a mounting rod, a connecting frame, a motor, and a propeller. By setting up the flaw detection mechanism, non-destructive testing can be performed after the wind turbine blades are installed, avoiding the cumbersome process of disassembling and installing the blades in traditional flaw detection methods. Simultaneously, the flaw detector can be driven by the motor and propeller to fly near the blades and automatically complete the detection, improving flaw detection efficiency and reducing operational difficulty. Multiple detection methods cooperate and cross-verify each other, effectively improving the accuracy of the detection results.
