Description

Technical Field

[0001] This utility model relates to the technical field of non-destructive testing equipment for welds, specifically to an all-around TOFD inspection scanning frame. Background Technology

[0002] In the field of non-destructive testing of welds, especially for comprehensive and accurate testing of complex welds, traditional technologies often face many challenges and are not very adaptable to complex operating environments.

[0003] According to the published new scanning frame for the inspection instrument (publication number: CN211785344U), it includes a scanning frame body and an inspection instrument mounted on the scanning frame body. A fixing block extends along one side of the scanning frame body in its width direction. A sliding groove is provided on the side wall of the fixing block along its length direction. Several sliders are slidably connected within the sliding groove. The end of each slider away from the sliding groove is connected to the inspection instrument via a connector. A locking device for fixing the sliders is provided on the top wall of the fixing block. Arranging multiple inspection instruments in a single row on the scanning frame body facilitates the determination of a unique detection starting point, allowing inspection personnel to quickly determine the location of weld damage points based on the inspection pattern, thereby improving inspection efficiency. Furthermore, using multiple inspection instruments is beneficial for comprehensive inspection of thick welds, demonstrating good adaptability.

[0004] While the design of the slider and groove in the aforementioned application increases the flexibility of the inspection instrument to some extent, its stability and accuracy are still lacking when dealing with extremely complex or irregular welds. Especially when the weld is located in a hard-to-reach position, this scanning frame may not be able to ensure that the inspection instrument can stably and accurately conform to the weld surface, thus affecting the reliability of the inspection results. Therefore, we propose an all-around TOFD inspection scanning frame. Utility Model Content

[0005] This invention proposes an all-around TOFD inspection scanning frame, which solves the problem in related technologies that cannot perform comprehensive and accurate inspection of complex welds.

[0006] The technical solution of this utility model is as follows:

[0007] This utility model is an all-around TOFD inspection scanning frame, including a control panel, a connecting line provided on the side of the control panel, and a scanning device provided at the end of the connecting line away from the control panel.

[0008] The scanning device includes a magnetic roller, which is located at the end of the connecting line away from the control panel. A stainless steel plate is fixedly connected through and to the top of the magnetic roller. A waist hole is opened at the top of the stainless steel plate. A probe clip is slidably connected to the inner side of the waist hole. A probe is provided on the side of the probe clip. A locking nut is threaded to the top of the probe clip. A hinge is fixedly connected to the top of the stainless steel plate. A limit hinge is fixedly connected to the top of the stainless steel plate.

[0009] Optionally, the locking nut has a buffer plate on its circumferential surface. The bottom of the buffer plate is located on the displacement trajectory of the top of the stainless steel plate. Its function is to buffer the movement and make the locking effect on the stainless steel plate better.

[0010] Optionally, the number of stainless steel plates is set to several, and the bottom of the limiting hinge and the hinge are fixedly connected to the top of another stainless steel plate. The function is to increase the stability of the stainless steel plate, so that it is not easy to shake during use and improve the detection accuracy.

[0011] Optionally, two hinges and two limiting hinges are provided, and several probe clips and probes are provided, arranged in pairs and symmetrically distributed along the vertical central axis of the stainless steel plate. This increases the detection range, enabling detection at different locations and improving detection efficiency. Simultaneously, providing multiple probe clips and probes also improves detection accuracy and avoids missed or false detections.

[0012] Optionally, a heat dissipation device is provided on the side of the control panel. The heat dissipation device includes a heat dissipation shroud, which is fixedly connected to the side of the control panel. A connecting plate is fixedly connected to the inner side of the heat dissipation shroud, and a mounting plate is fixedly connected to the side of the connecting plate. A motor is fixedly connected to the side of the mounting plate, and a driving bevel gear is fixedly connected to the output shaft of the motor. A rotating shaft is rotatably connected through the side of the connecting plate. A fan blade is fixedly connected to one end of the rotating shaft, and a driven bevel gear is fixedly connected to the end of the rotating shaft away from the fan blade. The function of this device is to dissipate heat from the control panel, preventing damage to the control panel due to overheating and improving the service life of the omnidirectional TOFD inspection scanning rack.

[0013] Optionally, the heat sink is provided with a support frame on its side. There are two support frames, which are symmetrically distributed along the vertical central axis of the heat sink. Their function is to support the heat sink, increase its stability, and prevent it from shaking during use, which would affect the heat dissipation effect.

[0014] Optionally, the driving bevel gear and the driven bevel gear mesh with each other, and the driving bevel gear has more teeth than the driven bevel gear. Its function is to increase the number of teeth of the driving bevel gear, so that the driving bevel gear can drive the driven bevel gear to rotate at a faster speed when rotating, thereby increasing the speed of the fan blades and enhancing the heat dissipation effect.

[0015] Optionally, the heat sink has several heat dissipation holes on its side. Located behind the control panel, the heat sink's function is to quickly dissipate heat generated by the control panel, further improving heat dissipation efficiency. Simultaneously, the heat sink's design also prevents dust and debris from entering the heat dissipation device, ensuring its cleanliness and lifespan.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] 1. This utility model achieves flexibility and accuracy in omnidirectional TOFD detection through the coordinated operation of components such as the magnetic roller, stainless steel plate, and waist hole in the scanning device. The magnetic roller design allows the scanning device to easily adhere to the surface to be inspected, facilitating movement and positioning. The robust structure of the stainless steel plate ensures the stability and durability of the scanning device, while the waist hole design allows the probe clamp to be flexibly adjusted within a certain range to adapt to different inspection needs. The locking nut ensures that the probe clamp is firmly fixed in the required position, preventing displacement or loosening during inspection, thereby improving the accuracy of the inspection.

[0018] 2. In this utility model, effective heat dissipation of the control panel is achieved through the cooperation of components such as the heat sink, connecting plate, and mounting plate in the heat dissipation device. The motor drives the active bevel gear to rotate. Due to the meshing relationship and the difference in the number of teeth between the active and driven bevel gears, the driven bevel gear drives the shaft and fan blades to rotate at a higher speed, thereby accelerating the flow of surrounding air and enhancing the heat dissipation effect. The design of the heat sink not only provides heat dissipation holes to promote the rapid dissipation of heat, but also protects the internal components of the heat dissipation device from dust and debris, ensuring the continuous and efficient operation of the heat dissipation device.

[0029] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] Example 1

[0031] Reference Figures 1-5 The first embodiment of this utility model proposes an all-around TOFD detection scanning frame, including a control panel 1, a connecting line 2 provided on the side of the control panel 1, and a scanning device 3 provided at the end of the connecting line 2 away from the control panel 1.

[0032] The scanning device 3 includes a magnetic roller 301, which is located at the end of the connecting line 2 away from the control panel 1. A stainless steel plate 302 is fixedly connected through the top of the magnetic roller 301. A waist hole 303 is opened on the top of the stainless steel plate 302. A probe clip 304 is slidably connected to the inner side of the waist hole 303. A probe 305 is provided on the side of the probe clip 304. A locking nut 306 is threadedly connected to the top of the probe clip 304. A hinge 307 is fixedly connected to the top of the stainless steel plate 302. A limit hinge 308 is fixedly connected to the top of the stainless steel plate 302.

[0033] The locking nut 306 has a buffer plate 4 on its circumferential surface. The bottom of the buffer plate 4 is located on the displacement trajectory of the top of the stainless steel plate 302. Its function is to buffer the movement of the buffer plate 4, so as to make the locking effect of the stainless steel plate 302 better.

[0034] The number of stainless steel plates 302 is set to several. The bottom of the limiting hinges 308 and 307 are fixedly connected to the top of another stainless steel plate 302. Their function is to increase the stability of the stainless steel plate 302, so that it is not easy to shake during use and improve the detection accuracy.

[0035] There are two hinges 307 and two limiting hinges 308, and several probe clips 304 and probes 305, arranged in pairs and symmetrically distributed along the vertical central axis of the stainless steel plate 302. Their function is to increase the detection range, enabling detection at different locations and improving detection efficiency. At the same time, the multiple probe clips 304 and probes 305 also improve detection accuracy and prevent missed or false detections.

[0036] In this embodiment, during use, the operator can control the omnidirectional TOFD inspection scanning frame through the control panel 1. The control panel 1 issues commands, which are transmitted to the scanning device 3 through the connecting line 2. The scanning device 3 starts working. When the scanning device 3 is working, the two stainless steel plates 302 achieve longitudinal and circumferential double folding through the 0°~270° lockable limiting hinges 308 and 307, so that the probe clamp 304 can adjust the included angle in real time according to the curvature of the workpiece. The magnetic roller 301 has a permanent magnet embedded in it. Under the continuous pressure of the reverse traction spring, it rolls along the curved surface and is firmly attracted, ensuring that the probe 305 is always in close contact with the inspection surface. The probe clamp in the waist hole 303 can slide and adjust the PCS. The locking nut 306 and the buffer plate 4 are used for secondary clamping to prevent the spacing drift caused by vibration. When inspecting small diameter circumferential seams, the longitudinal hinge 307 is retracted inward, and the probe clamp moves closer. When inspecting large curvature longitudinal seams, the limiting hinge 308 is extended outward, the included angle increases, and the sound beam is always perpendicular to the center of the weld.

[0037] Example 2

[0038] Reference Figures 1-5 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: a heat dissipation device 5 is provided on the side of the control panel 1. The heat dissipation device 5 includes a heat dissipation cover 501, which is fixedly connected to the side of the control panel 1. A connecting plate 502 is fixedly connected to the inner side of the heat dissipation cover 501. A mounting plate 503 is fixedly connected to the side of the connecting plate 502. A motor 504 is fixedly connected to the side of the mounting plate 503. A drive bevel gear 505 is fixedly connected to the output shaft of the motor 504. A rotating shaft 506 is rotatably connected through the side of the connecting plate 502. A fan blade 507 is fixedly connected to one end of the rotating shaft 506, and a driven bevel gear 508 is fixedly connected to the end of the rotating shaft 506 away from the fan blade 507. Its function is to dissipate heat from the control panel 1, preventing damage to the control panel 1 due to excessive temperature and improving the service life of the omnidirectional TOFD inspection scanning frame.

[0039] The heat sink 501 has a support frame 6 on its side. There are two support frames 6, which are symmetrically distributed along the vertical central axis of the heat sink 501. Their function is to support the heat sink 501, increase the stability of the heat sink 501, and prevent the heat sink 501 from shaking during use, which would affect the heat dissipation effect.

[0040] The driving bevel gear 505 meshes with the driven bevel gear 508. The driving bevel gear 505 has more teeth than the driven bevel gear 508. Its function is to increase the number of teeth of the driving bevel gear 505, so that the driving bevel gear 505 can drive the driven bevel gear 508 to rotate at a faster speed when it rotates, thereby increasing the speed of the fan blade 507 and enhancing the heat dissipation effect.

[0041] The heat sink 501 has several heat dissipation holes on its side. Located behind the control panel 1, the heat sink 501 serves to quickly dissipate the heat generated by the control panel 1, further improving heat dissipation efficiency. Simultaneously, the design of the heat sink 501 also prevents dust and debris from entering the heat dissipation device 5, ensuring its cleanliness and lifespan.

[0042] Compared to Embodiment 1, the working principle of the heat dissipation device 5 is simple and efficient. When the control panel 1 starts working, the motor 504 starts, and its output shaft drives the driving bevel gear 505 to rotate. Since the driving bevel gear 505 and the driven bevel gear 508 mesh with each other, and the driving bevel gear 505 has more teeth than the driven bevel gear 508, the driven bevel gear 508 will rotate at a higher speed. This increase in speed directly drives the shaft 506 and the fan blades 507 to rotate rapidly, thereby generating a strong airflow that effectively dissipates the heat generated by the control panel 1 through the heat dissipation holes.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
