Technical Field
[0001] The utility model relates to the technical field of non-destructive testing auxiliary equipment, and more specifically, to a T-shaped weld panel ultrasonic testing span control device. Background Art
[0002] Structural components with T-shaped welds are widely used in various fields of industrial production, such as chemical, shipbuilding, and military production. They primarily serve to connect and support the internal components of products and strengthen the outer shell. For example, T-shaped ribs in the shipbuilding industry typically have web thicknesses ranging from a few millimeters to tens of millimeters, but are often several meters to tens of meters long. They are directly responsible for the various stress changes transmitted by the ship's hull. Therefore, the quality requirements for non-destructive testing of these T-shaped welds are very high. Currently, the most effective method for detecting internal defects is ultrasonic testing.
[0003] With the development of non-destructive testing technology, the methods and requirements of various ultrasonic testing standards at home and abroad are becoming more and more stringent. For T-type welds, in recent years, both internationally and domestically, on the basis of the previous requirement of only web testing, relevant requirements for panel outer side testing have been added. However, when testing from the outside of the panel, it is impossible to accurately determine the position of the weld on the inside of the panel and the testing span. If the span is too short during testing, it is easy to miss the detection due to insufficient detection range. If the span is too long, it is easy to generate more interference waves due to the echo of the weld structure, resulting in false detection and misjudgment. There are high requirements for the experience and skill level of the testers. Due to the complexity of the test, the overall test efficiency is low, it is difficult to ensure the stability of the test, and it is very easy to miss the detection and false detection.
[0004] Therefore, it is necessary to propose a T-shaped weld panel outer side ultrasonic detection span control device to solve the above problems. Utility Model Content
[0005] The utility model provides a T-shaped weld panel ultrasonic detection span control device to solve the problem that the existing T-shaped weld panel outer side ultrasonic detection cannot accurately determine the position of the panel inner side weld and the detection span, the moving span is difficult to control during detection, errors are likely to occur and lead to misjudgment, the overall detection efficiency is low, it is difficult to ensure the stability of the detection and it is easy to cause missed detection and false detection.
[0006] According to one aspect of the utility model, a T-shaped weld panel ultrasonic detection span control device is provided, including a magnetic mounting seat and a flexible limiting rod, the magnetic mounting seats are arranged relatively at intervals, the flexible limiting rods are installed on the magnetic mounting seats at intervals, the magnetic mounting seat includes a guide rail and a magnetic seat, the guide rail is installed between the two magnetic seats, the flexible limiting rod is detachably installed on the guide rail, and a scale is provided on the guide rail.
[0007] Preferably, based on the above solution, a central positioning rod is provided in the middle of the guide rails of the two magnetic mounting seats.
[0008] Preferably, based on the above solution, there are multiple magnetic mounting seats, which are arranged at intervals on the outer side of the T-shaped weld panel.

[0010] Preferably, based on the above solution, the interface of the guide rail is T-shaped, both ends of the flexible limiting rod are provided with sliding grooves adapted to the guide rail, and locking screws are provided at both ends of the flexible limiting rod.
[0011] The utility model discloses a T-shaped weld panel ultrasonic detection span control device, which utilizes the properties of the weld panel and adopts a magnetic mounting base that can be adsorbed on the weld panel.

[0012] During use, according to the requirements of the relevant inspection standards for the inspection span of T-type welds of different plate thicknesses, in the two combined scale guide rails, according to the position of the weld on the inner side of the panel, after fixing the center positioning rod on the outer side of the panel, the span is determined by calculation. Combined with the probe size and the leading edge length, the position of the flexible limit rod can be determined and fixed with fastening bolts on both sides of the center positioning rod parallel to the T-type track. The probe is moved back and forth between the center positioning rod and the flexible limit rod to meet the inspection requirements for the T-type weld. It is convenient and quick to use, can effectively improve the overall inspection efficiency and ensure the stability of the inspection and the accuracy of the results.
[0013] Compared with the existing technology, the present invention determines the detection span by setting a center positioning rod and a flexible limit rod on the scale guide rail outside the panel according to the detection requirements. This avoids the problem of being unable to accurately determine the position of the inner panel weld on the outside of the panel and the detection span when testing on the outside of the panel. It also avoids the problem that a span that is too short can easily lead to missed detection due to insufficient detection range, while a span that is too long can easily lead to false detection and misjudgment due to excessive interference waves generated by the weld structure echo. At the same time, it reduces the experience and skill level requirements of the inspection personnel, reduces the complexity of the inspection, effectively improves the overall inspection efficiency, ensures the stability of the inspection, and greatly improves the inspection personnel's working method.

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.
[0028] See also Figure 1 , and combined with Figure 2 and Figure 3 As shown, the utility model is a T-type weld panel ultrasonic detection span control device, which is used to detect the welding quality of the T-type weld panel. In view of the complexity of the existing detection method, the overall detection efficiency is low, it is difficult to ensure the stability of the detection, and it is very easy to miss the detection, and a new auxiliary detection tool is proposed.
[0029] The T-shaped weld panel ultrasonic detection span control device of the present invention includes a magnetic mounting seat and a flexible limiting rod 2. The magnetic mounting seats are arranged at relative intervals to achieve the relative position positioning of the structure of the present invention and the weld steel plate, and provide an installation basis. The flexible limiting rods 2 of the present invention are arranged at intervals on the magnetic mounting seat. Multiple flexible limiting rods 2 can be set as needed to limit the relative position of the movement between the probe 7 and the weld. Furthermore, the present invention also has a center positioning rod 3 in the middle of the guide rail 11 of the two magnetic mounting seats.
[0030] Specifically, the magnetic mounting base of the present invention includes a guide rail 11 and a magnetic base 12. The guide rail 11 is installed between the two magnetic bases 12. The guide rail 11 can be connected to the magnetic base 12 in various ways such as slots, threads, and rivets. It should be noted that when the switch of the magnetic base 12 of the present invention is turned on, the magnetic base 12 generates magnetic force and can be firmly adsorbed on the surface of the weld panel. When the switch of the magnetic base 12 is turned off, the magnetic force of the magnetic base 12 disappears and it can be easily removed from the weld surface.
[0031] Among them, the flexible limit rod 2 can be detachably installed on the guide rail 11, and a ruler 13 is set on the guide rail 11. The ruler 13 is placed in the side slot of the guide rail 11 and fixed with bolts or other means. After calculating the required range of movement of the probe 7, the position of the flexible limit rod 2 relative to the center positioning rod 3 can be determined according to the ruler 13. At the same time, the ruler can be easily replaced according to the imperial or metric length adopted by different standards.
[0032] The center positioning rod 3 and the flexible limiting rod 2 of the utility model are both moved on the guide rail 11 and fixed by locking screws 6 or other means. A plurality of long grooves are respectively opened on the center positioning rod 3 and the flexible limiting rod 2. When needed, the long grooves can be used to connect multiple center positioning rods 3 or multiple flexible limiting rods 2 to adapt to the different spacings between the two scale 13 guide rails 11 of different products.
[0033] It should be noted that when the T-shaped weld panel is an arc or other shape, the center positioning rod 3 and the flexible limit rod 2 can be made into corresponding arcs to adapt to changes in the panel shape, or they can be made of flexible materials and flexibly matched with the panel shape during installation.
[0034] Among them, there are multiple magnetic mounting seats, which are arranged at intervals on the outer side of the T-shaped weld panel. The interface of the guide rail 11 of the utility model is T-shaped, and the two ends of the flexible limit rod 2 are provided with sliding grooves adapted to the guide rail 11, and locking screws 6 are provided at both ends of the flexible limit rod 2.
[0035] The steps for using the ultrasonic detection span control device for T-shaped weld panels of the utility model are as follows:
[0036] 1. When it is necessary to detect the outside of the T-shaped weld panel with an oblique probe 7, first fix the two guide rails 11 on the outside of the T-shaped panel at a certain distance perpendicular to the length direction of the weld through the magnetic base 12. This distance is determined according to the technical requirements of the product.
[0037] 2. By measuring the distance from the T-weld on the inner side of the panel to the upper end of the panel, at the corresponding position on the outer side of the panel, fix the two ends of the center positioning rod 3 to the guide rail 11 of the ruler 13 with locking screws 6.
[0038] 3. According to the detection requirements of relevant standards, calculate the span required for the angle probe 7 to detect, and combine the length and leading edge of the probe 7 to determine the length of the moving area required for the angle probe 7 to detect one span.
[0039] 4. According to the markings on the scale on the side of the guide rail 11 of the ruler 13, place the two flexible limit rods 2 on both sides of the central positioning rod 3 according to the length of the moving area, and fix them with locking screws 6.
[0040] 5. Move the oblique probe 7 back and forth within the moving area on one side of the center positioning rod 3. When moving, the front and rear ends of the probe 7 reach the center positioning rod 3 and the flexible limit rod 2 respectively. Combined with normal detection techniques, the weld on one side can be effectively detected.
[0041] 6. On the other side of the center positioning rod 3, the weld on the other side can be effectively inspected using the same method.
[0042] When using a straight probe 7 to inspect the outside of the T-shaped weld panel, the same steps as above can be taken. The only difference is that after determining the position of the T-shaped weld on the outside of the panel, there is no need to use the center positioning rod 3 for center positioning. Instead, the flexible limit rods 2 are directly fixed on the edges of the detection area on both sides of the outside of the panel at that position, and the straight probe is moved between the two flexible limit rods 2 for detection.
[0043] The utility model discloses a T-shaped weld panel ultrasonic detection span control device, which utilizes the properties of the weld panel and adopts a magnetic mounting base that can be adsorbed on the weld panel. The movement position of the probe can be limited by the limiting effect of the flexible limiting rod 2 to ensure the relative position between the probe and the weld, improve the detection accuracy, avoid the problem of missed detection or false detection, and is easy and quick to use, and convenient to disassemble and transport.
[0044] During use, according to the requirements of the relevant inspection standards for the inspection span of T-shaped welds of different plate thicknesses, in the two combined scale 13 guide rails 11, according to the position of the weld on the inner side of the panel, after fixing the center positioning rod 3 on the outer side of the panel, the span is determined by calculation. Combined with the size of the probe 7 and the front length, the position of the flexible limit rod 2 can be determined and fixed with locking screws 6 on both sides of the T-shaped track parallel to the center positioning rod 3. The probe 7 is moved back and forth between the center positioning rod 3 and the flexible limit rod 2 to meet the inspection requirements for the T-shaped weld. It is convenient and quick to use, can effectively improve the overall inspection efficiency and ensure the stability of the inspection and the accuracy of the results.
[0045] Compared with the prior art, the present invention determines the detection span by setting a center positioning rod 3 and a flexible limit rod 2 on the guide rail 11 of the scale 13 on the outside of the panel according to the detection requirements. This avoids the problem of being unable to accurately determine the position of the inner panel weld on the outside of the panel and the detection span when testing on the outside of the panel. If the span is too short, it is easy to miss the detection due to insufficient detection range. If the span is too long, it is easy to generate more interference waves due to the echo of the weld structure, leading to false detection and misjudgment. At the same time, the requirements for the experience and skill level of the inspection personnel are reduced, the complexity of the inspection is reduced, the overall inspection efficiency is effectively improved, the stability of the inspection is guaranteed, and the inspection personnel's working method is greatly improved.
[0046] Finally, the method of this application is only a preferred embodiment and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of this utility model should be included in the scope of protection of this utility model.
