[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figure 1 shown, the steel pipe ultrasonic probe holder of this embodiment includes a probe connection bracket 1, a cage 7, and a pressing plate 2. Among them, the probe connection bracket 1 includes a first support rod 13, a cross beam 14, and a second support rod 15. Both the first support rod 13 and the second support rod 15 are fixedly connected to both side surfaces of the cage 7 through guide post nuts 8. The first support rod 13, the cross beam 14, and the second support rod 15 are an integrally formed structure.

[0022] A number of positioning and mounting holes are provided in the upper part of the first support rod 13 for connecting the probe connection bracket 1 to the guide rail on the trolley of the long pipe ultrasonic detector to drive the movement of the entire device.

[0023] The probe connection bracket 1 is used to install the ultrasonic probe, specifically to fixedly install the ultrasonic probe on the cross beam 14. In this embodiment, the illustration of the ultrasonic probe is not shown separately, and those skilled in the art can select the installation position and the number of installations according to the actual situation.

[0024] In practical applications, a probe mounting box 11 and a cage guide wheel 10 are connected to the inner side of the cage 7. The cage guide wheel 10 includes a first cage guide wheel and a second cage guide wheel, and the probe mounting box 11 is placed between the first cage guide wheel and the second cage guide wheel. Among them, the probe mounting box 11 is a box body with a central connection. The probe mounting box 11 is installed on the cage 7 through a probe guide wheel 12, and the cage guide wheel 10 is fixed in the cage 7 through a guide wheel shaft 9. The ultrasonic probe can pass through the probe mounting box 11, the direction of the ultrasonic probe is downward, and it is detachably installed in the probe mounting box 11. When using this device, the position of the steel pipe to be detected is located below the cage 7. When the steel pipe rotates, the cage guide wheel 10 is used to directly contact the steel pipe, thus avoiding the direct contact between the ultrasonic probe and the steel pipe, so the ultrasonic probe will not be worn. Since the middle of the probe mounting box 11 is connected, circulating water can be additionally injected from above to form a water film, and the ultrasonic probe performs flaw detection on the steel pipe through the water film.

[0025] In practical applications, a pressure plate 2 is placed above the cage 7, and the central position of the pressure plate 2 corresponds to the opening position of the probe mounting box 11. In this embodiment, the pressure plate 2 is installed on the cage 7 through four threaded guide posts 3. A polyurethane pad 6 is also sleeved on the threaded guide post 3. The threaded guide post 3 passes through the pressure plate 2 and the polyurethane pad 6 and is fixed on the cage 7. An adjusting nut 4 is provided at the top of the threaded guide post 3, and a spring 5 is sleeved between the adjusting nut 4 and the pressure plate 2. By rotating the adjusting nut 4, the compression degree of the spring 5 can be adjusted, so as to adjust the magnitude of the positive pressure. When the cage guide wheel 10 contacts the steel pipe, even if the steel pipe has a slight jump during rotation, the cage 7 can be kept in close contact with the steel pipe at all times through the up and down movement of the spring 5, ensuring a constant distance between the ultrasonic probe and the steel pipe and avoiding damage to the ultrasonic probe.

[0026] During operation, connect the steel pipe ultrasonic probe bracket of this embodiment to the guide rail on the trolley of the long pipe ultrasonic flaw detector. The guide rail on the trolley drives the bracket to move downward, so that the cage guide wheel 10 contacts the steel pipe. When the steel pipe rotates, the cage guide wheel 10 moves with the rotation of the steel pipe. At the same time, circulating water is continuously injected above the probe mounting box 11 to generate a water film between the ultrasonic probe and the steel pipe, and the generated water film is uniform and stable. The ultrasonic probe passes through the probe mounting box 11 to perform flaw detection on the steel pipe. Since the ultrasonic probe does not directly contact the steel pipe, the loss of the ultrasonic probe is basically zero, and due to the adjustment of the spring 5, the ultrasonic probe can maintain a consistent distance from the steel pipe very well, and the flaw detection accuracy is higher, which can avoid false alarms and missed alarms.

[0027] The above embodiments are preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious substitution without departing from the concept of the technical solution is within the scope of the present invention patent.

[0028] In order to enable those of ordinary skill in the art to more conveniently understand the improvements of the present invention over the prior art, some of the drawings and descriptions of the present invention have been simplified. And for the sake of clarity, some other elements have also been omitted in this application document. Those of ordinary skill in the art should be aware that these omitted elements may also constitute the content of the present invention.
