[0026] like Figure 3 As shown, the ultrasonic detection mechanism 4 includes an ultrasonic probe 41 and an ultrasonic detection circle 42. A support frame 43 is provided above the first fixing mechanism 2. The side of the support frame 43 away from the motor 21 is connected to the first electric push rod 45 through a telescopic rod 44.

Similarly, the second bearing enables the second support plate 32 to have the same effect.

[0034] Furthermore, when the welding steel 5 is a long steel, the welding steel can be placed horizontally and clamped in the width direction for detection. At this time, a rotation connection should be selected between the support rod 43 and the telescopic rod 44, and a rotation connection should also be selected between the telescopic rod 44 and the first electric push rod 45, so that the ultrasonic probe 41 can rotate at multiple angles, thereby realizing multi-angle detection of the weld. At the same time, the ultrasonic probe 41 can also be placed in the corresponding ultrasonic detection circle 42 according to its position, ensuring the coordinated use of the ultrasonic probe 41 and the ultrasonic detection circle 42, further improving the accuracy and effect of the detection. If there are many weld positions on the welding steel 5, a pushing device or a pulling device can be set on one side of the utility model to adjust the welding steel 5 so that multiple weld positions of the longer welding steel can be detected. This technical solution not only ensures the stability of the long welding steel 5 during the detection process, but also improves the detection efficiency, making the all-round detection of long steel more convenient and efficient.

[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
