[0002] With the continuous improvement of industrial manufacturing, welding technology has been widely used in various industries, including the welding of high-temperature heating surface pipes. However, welding in high-temperature environments can lead to quality problems in welded joints. Ultrasonic imaging can provide highly sensitive inspection of welded joints, detecting minor defects, pores, cracks, and other issues, helping to identify potential quality issues. Therefore, ultrasonic imaging technology can be used to inspect high-temperature heating surface pipe joints after welding.

[0003] The welded joints of high-temperature heated surface pipes are often cylindrical weld bands, and ultrasonic probes must ensure comprehensive inspection of the welded joints. During inspection, the probe is usually moved manually around the heated surface pipe. This not only exposes the probe to the heat of the heated surface pipe, but also easily increases probe shake during manual operation, affecting the inspection and imaging results. Therefore, a new ultrasonic imaging inspection device is needed to improve this. Utility Model Content

[0004] The technical problem to be solved by the present invention is that when an ultrasonic probe is moved around a heated surface pipe for imaging detection, workers are easily burned by the high temperature, and manual movement of the ultrasonic probe easily increases the instability of the probe, affecting the imaging effect.

[0005] In order to solve the above problems, the utility model proposes a technical solution: an ultrasonic imaging detection device for high-temperature heated surface pipe welded joints, comprising a detection box, a display screen is provided on the detection box, and an ultrasonic probe is connected to the circuit on the detection box; the detection cylinder is also included, and the detection cylinder is sleeved on the pipeline welding position; a rotating cylinder is rotatably provided in the detection cylinder, and the ultrasonic probe is fixedly provided on the inner wall of the rotating cylinder, and the position of the ultrasonic probe corresponds to the pipeline welding position; an operating cylinder is fixedly sleeved on the rotating cylinder; a clamping structure is provided in the detection cylinder, and the clamping structure generates a clamping force on the pipeline.

[0008] As an improvement, the clamping structure is provided with two corresponding groups; the clamping structure includes a clamping plate and a connecting rod, the two clamping plates are engaged with each other, and the pipeline is located inside the two clamping plates; two connecting rods are fixedly connected to the clamping plate, and the connecting rods slide through the detection cylinder.

[0009] As an improvement, a spring sleeved on the connecting rod is provided inside the detection cylinder, and the spring has a reserved compression amount; an operating block fixedly connected to the connecting rod is provided outside the detection cylinder.

[0010] As an improvement, a heat insulation layer is provided in both the detection cylinder and the rotating cylinder.

[0011] Beneficial effects of the utility model:

[0012] 1. The detection tube is placed on the welding position of the pipeline. A rotating tube is provided inside the detection tube, and the ultrasonic probe is fixed on the inner wall of the rotating tube. By setting the detection tube and the rotating tube, most of the heat on the pipeline can be isolated, avoiding being roasted by high temperature during ultrasonic detection and imaging.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] according to Figure 1-4As shown: The utility model provides an ultrasonic imaging detection device for high-temperature heated surface pipe welded joints: it includes a detection box 1, a display screen 6 is provided on the detection box 1, and an ultrasonic probe 11 is connected to the circuit of the detection box 1; it also includes a detection cylinder 3, the detection cylinder 3 is sleeved on the welding position of the pipeline 2, and the ultrasonic probe 11 is located in the detection cylinder 3; a rotating cylinder 4 is rotatably arranged in the detection cylinder 3, the ultrasonic probe 11 is fixedly arranged on the inner wall of the rotating cylinder 4, and the position of the ultrasonic probe 11 corresponds to the welding position of the pipeline 2; an operating cylinder 5 is fixedly sleeved on the rotating cylinder 4; a clamping structure is provided in the detection cylinder 3, and the clamping structure generates a clamping force on the pipeline 2.

[0021] By setting up the detection cylinder 3 and the rotating cylinder 4, most of the heat on the pipeline 2 can be isolated, avoiding the staff from being burned by high temperature during ultrasonic detection and imaging; at the same time, by setting up the clamping structure, the stability of the ultrasonic probe 11 during rotation detection can be increased, avoiding affecting the imaging effect.

[0022] As the instruction manual Figure 4 As shown, a limit groove 16 is provided in the detection cylinder 3, and a limit rod 15 is fixedly connected to the rotating cylinder 4. The limit rod 15 is located in the limit groove 16, which can limit the horizontal displacement of the rotating cylinder 4 to a certain extent, thereby reducing the possibility of the rotating cylinder 4 detaching from the detection cylinder 3; a through groove 17 connected to the limit groove 16 is provided on one side of the detection cylinder 3, and the size of the through groove 17 corresponds to the limit rod 15. When the limit rod 15 corresponds to the through groove 17, the rotating cylinder 4 and the ultrasonic probe 11 can be easily removed.

[0023] A fixing ring 12 is fixedly provided on the inner wall of the detection cylinder 3, and a circular groove 13 is opened on one side of the fixing ring 12; a circular block 14 is fixedly provided at one end of the rotating cylinder 4 and is inserted into the groove 13, and the block 14 is rotatably arranged in the groove 13, which can guide the rotation of the rotating cylinder 4 relative to the detection cylinder 3.

[0024] As the instruction manual Figure 3 、 4 As shown, the clamping structure is provided with two corresponding groups; the clamping structure includes clamping plates 7 and connecting rods 9. The two clamping plates 7 engage with each other, and the pipe 2 is located within the two clamping plates 7. Two connecting rods 9 are fixedly connected to the clamping plates 7, and the connecting rods 9 slide through the detection cylinder 3. A spring 10 is installed inside the detection cylinder 3 and is sleeved on the connecting rods 9. The spring 10 has a reserved compression capacity to continuously apply pressure to the clamping plates 7, thereby increasing the relative fixation between the pipe 2 and the detection cylinder 3. An operating block 8 is fixedly connected to the connecting rods 9 on the outside of the detection cylinder 3. This allows personnel to pull the connecting rods 9 from the outside of the detection cylinder 3 to reduce the risk of being burned by the high temperature of the pipe 2.

[0025] Heat insulation layers are provided inside the detection cylinder 3 and the rotating cylinder 4 , which greatly improves the heat insulation effect of the detection cylinder 3 and the rotating cylinder 4 .

[0026] Principle of the utility model

[0027] When performing ultrasonic imaging detection on the welding position of the pipe 2, the detection tube 3 must first be placed on the pipe 2. Figure 3 As shown, the operating block 8 is pulled to cause the connecting rod 9 to drive the clamping plate 7 to move upward, and the clamping plate 7 compresses the spring 10. After the detection cylinder 3 is placed on the pipe 2, the operating block 8 is released. Under the action of the rebound force of the spring 10, the clamping plate 7 is pressed against the pipe 2, thereby ensuring the relative fixation of the detection cylinder 3 and the pipe 2 and increasing the stability of the ultrasonic probe 11 relative to the pipe 2.

[0028] like Figure 1-2 As shown, the welded portion of pipe 2 is within the coverage of detection cylinder 3 and rotating cylinder 4, isolating most of the heat from the heated surface pipe. When the operator rotates operating cylinder 5 to drive ultrasonic probe 11, it is not exposed to high temperatures. Furthermore, ultrasonic probe 11 maintains high stability as it rotates around pipe 2, ensuring effective imaging.

[0029] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
