[0002] In industries such as oil, natural gas, and chemicals, pipelines serve as the primary means of material transport, and their safety and reliability are of paramount importance. Pipeline systems are typically constructed by welding long sections of steel pipe together to form a continuous material transport channel. At the circumferential weld, defects such as cracks, slag inclusions, and incomplete fusion can easily occur. These defects directly affect the overall strength and sealing performance of the pipeline, and in severe cases, may lead to material leakage or even safety accidents. Therefore, the inspection of pipeline circumferential welds is essential.

[0003] To improve the efficiency and accuracy of pipeline circumferential weld inspection while reducing inspection costs, automated inspection equipment for pipeline circumferential welds has emerged.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Multiple pipe sections are typically connected by welding, resulting in a circumferential weld at the joint between adjacent pipes. A pipe circumferential weld inspection device uses X-ray imaging technology to inspect this weld.

[0028] The pipeline circumferential weld inspection device includes a toothed steel belt, two traveling frames 7, an imaging plate, and a X-ray machine. The toothed steel belt wraps around the pipeline, and the traveling frames 7 can move on the toothed steel belt. The two traveling frames 7 are arranged opposite each other and move synchronously. The X-ray machine is mounted on one traveling frame 7, and the imaging plate is mounted on the other traveling frame 7. During the synchronous movement of the two traveling frames 7, the X-ray machine emits weld inspection X-rays in real time. These X-rays pass through the weld and are received by the imaging plate, thereby forming an image to show the weld quality for evaluation. The principle of this X-ray inspection is existing technology.

[0029] The imaging plate of the pipeline annular weld inspection device of this utility model includes an imaging panel 1, a communication box 2, a connecting frame 3, rollers 4, a protective plate 5, and a handle 6, which are used to be installed on one of the walking frames 7 to receive weld inspection rays emitted by the X-ray machine.

[0030] The imaging panel 1 includes a housing 11 and a heat sink 12. The X-ray receiving and processing elements of the imaging panel 1 are installed inside the housing 11. The heat sink 12 is integrally formed on the outside of the housing 11. Multiple heat sinks 12 are provided and arranged in a matrix with intervals. The heat sink 12 not only increases the effective heat dissipation area of ​​the imaging panel 1, but also forms an air duct (the interval between two adjacent heat sinks 12) that can guide airflow, making the convective heat transfer effect of the imaging panel 1 better, thereby improving the heat dissipation capacity of the imaging panel and ensuring the normal operation of the imaging panel.

[0031] To further improve the heat dissipation capacity of the imaging panel 1, it is preferable to make the imaging panel 1 from materials such as aluminum alloy.

[0032] In a preferred embodiment, the heat sink 12 is cubic in shape, and two of its sides are perpendicular to the axis of the pipe to be tested. When the imaging panel 1 rotates around the axis of the pipe, a good airflow can be formed to accelerate the flow of air.

[0033] The communication box 2 is fixed to the housing 11 by bolts. Preferably, a wireless network module is installed inside the communication box 2, allowing the detection information received by the imaging panel 1 to be directly connected to the network for wireless transmission, which greatly improves the ease of use of the pipeline annular weld inspection device. The wireless network module is existing technology.

[0034] During the inspection of the weld, the electrical components inside the communication box 2 will also generate heat. If this heat cannot be dissipated in time, it will affect the normal operation of the communication box 2. At the same time, the communication box 2 and the imaging panel 1 are interconnected, and the heat generated by the two will also affect each other.

[0035] To solve the above problems, the communication box 2 is placed against the heat sink 12 on the side away from the housing 11. This not only reduces the mutual influence of heat generated by the communication box 2 and the imaging panel 1, but also allows the heat inside the communication box 2 to be transferred to the heat sink 12 and quickly dissipated through the heat sink 12, thus ensuring the normal operation of the communication box 2.

[0036] The communication box 2 includes a box body 21 and multiple connecting posts 22, such as Figure 2 and Figure 4 As shown, the relevant communication components are installed inside the housing 21, which is abutted against the heat sink 12. The connecting post 22 is fixedly installed on the housing 21 and abuts against the shell 11. The connecting post 22 and the shell 11 are fixedly connected by bolts, thereby improving the stability of the communication box 2.

[0037] like Figure 1 As shown, the connecting frame 3 is fixedly mounted on the housing 11, and the connecting frame 3 is fixedly connected to the walking frame 7. The imaging panel 1 is fixed on the walking frame 7 by the connecting frame 3, so that the imaging panel 1 can move with the walking frame 7.

[0038] Since the imaging panel 1 needs to be aligned with the weld seam of the pipe, and the traveling frame 7 needs to correspond to the position on the pipe without weld seam, the imaging panel 1 is installed on one side of the traveling frame 7, that is, the imaging panel 1 is in a cantilevered state. During the movement of the traveling frame 7, the imaging panel 1 is prone to shaking. To address this, a roller 4 is installed on the imaging panel 1. The roller 4 is located on the side of the imaging panel 1 away from the traveling frame 7 and is in rolling connection with the side wall of the pipe. The support of the end of the imaging panel 1 away from the connecting frame 3 by the roller 4 can not only improve the stability of the movement of the imaging panel 1, but also avoid interference and collision between the imaging panel 1 and the pipe.

[0039] In one preferred embodiment, the roller 4 includes an inner ring 41 and an outer ring 42, such as Figure 2 As shown, the inner ring 41 is fixedly mounted on the imaging panel 1, and the outer ring 42 is rotatably mounted on the outside of the inner ring 41. When the imaging panel 1 inspects the pipe weld, the outer ring 42 is pressed against the side wall of the pipe and the outer ring 42 is rolled to connect with the side wall of the pipe.

[0040] Since the inner ring 41 is fixedly connected to the imaging panel 1, the connection between the roller 4 and the imaging panel 1 is relatively stable, which can prevent the imaging panel 1 from shaking during movement.

[0041] like Figure 2 and Figure 3As shown, the imaging panel 1 also includes a protrusion 13, which is integrally formed in the middle of the side of the housing 11 away from the walking frame 7. The inner ring 41 is fixedly mounted on the protrusion 13, and the inner diameter of the outer ring 42 is larger than the outer diameter of the protrusion 13. This can prevent the outer ring 42 from rubbing against the imaging panel 1 during rotation, thereby improving the service life of the imaging panel.

[0042] The protective plate 5 is used to protect the housing 11. The protective plate 5 is fixed to the side of the housing 11 away from the communication box 2 by bolts to prevent the housing 11 from colliding with other components and damaging the X-ray receiving components inside the housing 11. The protective plate 5 is preferably made of carbon fiber.

[0043] like Figure 1 As shown, the handle 6 is fixedly mounted on the housing 11 and located on the side of the communication box 2 away from the walking frame 7. The pipe annular weld inspection device can be manually moved by holding the handle 6 and the walking frame 7, which improves the portability of the device.

[0044] The working principle of the imaging plate of the pipeline circumferential weld inspection device of this utility model is as follows:

[0045] like Figure 2 As shown, during the testing process, the electrical components inside the housing 11 and the communication box 2 will generate heat. Since the heat sink 12 is abutted between the housing 11 and the communication box 2, and there is a gap between the multiple heat sinks 12, the heat on the housing 11 and the communication box 2 can be dissipated quickly, and the heat interference between the housing 11 and the communication box 2 can be reduced, thus ensuring the normal operation of the imaging board.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
