Description

Technical Field

[0001] This utility model relates to the field of pipeline flaw detection technology, and in particular to a non-destructive testing device for high-temperature pipelines. Background Technology

[0002] Non-contact flaw detection for high-temperature pipelines utilizes technologies such as infrared thermal imaging, ultrasonic phased array, and electromagnetic eddy current to detect internal and surface defects in pipelines without physical contact with the high-temperature pipes. It avoids the harm to equipment and personnel caused by high temperatures, enabling long-distance, real-time monitoring. It is suitable for detecting cracks, corrosion, and other defects in high-temperature pipelines in boilers, chemical plants, and other applications, ensuring the safe operation of equipment.

[0003] Traditional flaw detection equipment relies heavily on manual assistance during operation. After the flaw detection device completes a section of inspection above the pipeline, the pipeline's position must be manually adjusted before inspection of other areas can proceed. This repeated start-stop and manual intervention not only reduces inspection efficiency but also exposes operators to radiation generated during the flaw detection process, significantly increasing health risks. Therefore, the industry urgently needs a systematic high-temperature pipeline non-destructive testing device that can achieve automated operation and comprehensive inspection to address the dual challenges of manual dependence and radiation hazards.

[0004] Based on this, a non-destructive testing device for high-temperature pipelines is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a non-destructive testing device for high-temperature pipelines in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A non-destructive testing device for high-temperature pipelines includes a placement groove, a testing frame connected to the placement groove, a testing terminal connected to the testing frame, a transmitter connected to the testing terminal via a cable, the transmitter being slidably connected to the testing frame, and a transmission mechanism connected to one side of the transmitter for driving the transmitter to slide on the testing frame.

[0008] Preferably, the transmission mechanism includes a turntable, a rotating rod connected to the turntable, a traction bar rotatably connected to the rotating rod, a sliding column connected to the other end of the traction bar, the launching end rotatably connected to the sliding column, and a motor connected to one side of the turntable.

[0009] Preferably, a fixed frame is connected to one side of the placement slot, and a driven gear is connected to one side of the turntable, with the driven gear rotatably connected to one side of the fixed frame.

[0010] Preferably, a motor is connected to one side of the fixing frame, and a missing gear is connected to the output end of the motor. The tooth structure on the missing gear meshes with the driven gear.

[0011] Preferably, a cylinder is connected to the placement slot, and a push plate is connected to the telescopic end of the cylinder.

[0012] Preferably, the detection frame is connected to a sensor for controlling the operation of the cylinder.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. This application adopts a gear-deficient structure, which enables the transmitter to intermittently perform flaw detection on high-temperature pipelines. When the transmitter stops moving, the sensor is pressed, and the cylinder can push the high-temperature pipeline to move, thereby changing the flaw detection area of ​​the pipeline. Then the transmitter continues to move to perform flaw detection on the area to be tested until the flaw detection of the entire pipeline is completed, thus realizing comprehensive flaw detection operation on high-temperature pipelines.

[0015] 2. This application adopts a detection frame structure, which uses a detection frame set on a high-temperature pipeline to limit the movement of the transmitter, ensuring that the transmitter can move horizontally back and forth. This non-contact detection reduces wear on the pipeline surface and improves detection accuracy. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] See also Figures 1-3 This utility model provides a technical solution:

[0023] A non-destructive testing (NDT) device for high-temperature pipelines includes a placement tank 1, a testing frame 2 connected to the placement tank 1, a testing terminal 9 connected to the testing frame 2, and a transmitter 13 connected to the testing terminal 9 via a cable. The transmitter 13 enables non-contact testing. The transmitter 13 and the testing terminal 9 are direct references to existing technologies. The transmitter 13 is slidably connected to the testing frame 2. The sliding of the transmitter 13 changes the testing area, enabling overall pipeline testing and improving testing accuracy. A transmission mechanism is connected to one side of the transmitter 13 to drive the transmitter 13 to slide on the testing frame 2. No manual intervention is required during the testing process, improving testing accuracy, avoiding external interference, and not affecting the human body, thus improving the safety of the equipment.

[0024] Specifically, such as Figure 1 and Figure 3 As shown, the transmission mechanism includes a turntable 7, on which a rotating rod 12 is connected. The rotating rod 12 is eccentrically connected to one side of the turntable 7. A traction bar 8 is rotatably connected to the rotating rod 12. A sliding column 14 is connected to the other end of the traction bar 8. The sliding column 14 is vertically connected to one end of the traction bar 8 and is slidably connected to the detection frame 2. The transmitting end 13 is rotatably connected to the sliding column 14. A motor 5 is connected to one side of the turntable 7, which can drive the turntable 7 to rotate.

[0025] Specifically, such as Figure 2 As shown, a fixed frame 10 is connected to one side of the placement slot 1, and a driven gear 11 is connected to one side of the turntable 7. The driven gear 11 is rotatably connected to one side of the fixed frame 10, and the fixed frame 10 ensures the stability of the rotation of the driven gear 11 and the missing gear 6.

[0026] Specifically, such as Figure 3 As shown, a motor 5 is connected to one side of the fixed frame 10, and a missing gear 6 is connected to the output end of the motor 5. The tooth structure on the missing gear 6 meshes with the driven gear 11.

[0027] Specifically, such as Figure 2 and Figure 3As shown, a cylinder 3 is connected to the placement slot 1, and a push plate 4 is connected to the extension end of the cylinder 3. The operation of the cylinder 3 is controlled by a sensor 15, which senses the pressure and controls the cylinder 3 to extend.

[0028] Specifically, such as Figure 3 As shown, a sensor 15 for controlling the operation of cylinder 3 is connected to the detection frame 2.

[0029] In summary, the non-destructive testing device for high-temperature pipelines provided in this embodiment requires placing the pipeline on the placement groove 1 and abutting one end of the pipeline against the side of the push plate 4 when it is necessary to test the high-temperature pipeline. Then, the testing terminal 9 and the motor 5 are started.

[0030] When the motor 5 starts, it can drive the missing gear 6 to rotate. The missing gear 6 is an incomplete gear with a missing tooth structure. When the missing gear 6 rotates, it can drive the driven gear 11 meshing with it to rotate, thereby causing the turntable 7, which is fixedly connected to the driven gear 11, to rotate. When the turntable 7 rotates, it can work with the traction bar 8 to pull the transmitter 13 to slide on the detection frame 2 to detect the pipe located below.

[0031] When the missing gear 6 rotates until the missing tooth part engages with the driven gear 11, the missing gear 6 rotates, but the driven gear 11 does not rotate. At this time, the sliding column 14 will abut against the sensor 15. Then, the sensor 15 controls the cylinder 3 to extend, pushing the pipe to move on the placement slot 1, changing the position of the pipe, and moving the next area to be tested to below the detection frame 2. When the tooth structure on the missing gear 6 meshes with the driven gear 11, the sliding column 14 moves away from the sensor 15, the cylinder 3 stops operating, and the transmitter 13 begins to detect flaws in the pipe.

[0032] As the motor 5 operates, the transmitter 13 can perform flaw detection on the entire pipeline. Since it is a non-contact flaw detection, it can achieve a non-destructive flaw detection effect and avoid wear on the pipeline surface.

[0033] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
