Description

Technical Field

[0001] This utility model relates to the field of flaw detector technology, specifically to a flaw detection wear-resistant boot and a flaw detector. Background Technology

[0002] Existing GE ultrasonic flaw detector probe wear-resistant boots, such as Figure 1 , Figure 2 and Figure 3 As shown, the probe wear-resistant boot includes a wear-resistant boot body 1, two rectangular first pressure plates 2, and two water-blocking plates 4. Two elongated through holes 101 are respectively opened at the left and right ends of the wear-resistant boot body 1. A rectangular groove is respectively opened on the left and right sides of the top of the wear-resistant boot body 1, with each rectangular groove corresponding to one of the through holes 101. The rectangular grooves are located outside the through holes 101 and are connected to their corresponding through holes 101. Two countersunk holes are opened on the inner bottom wall of the rectangular grooves. Two mounting holes corresponding to the countersunk holes are opened on the first pressure plates 2. The first pressure plates 2 are fixedly installed onto the rectangular grooves using two countersunk screws 3. The two water-blocking plates 4 are sealed inside the through holes 101 and located at the bottom of the wear-resistant boot body 1.

[0003] like Figure 1 As shown, after the first pressure plate 2 is installed, since the length of the first pressure plate 2 is the same as that of the rectangular groove 102, but the length of the first pressure plate 2 is less than that of the through hole 101, the first pressure plate 2 cannot completely seal the through hole 101. Water will flow into the through hole 101 from both sides of the length direction of the first pressure plate 2, increasing the burden on the baffle plate 4. Once the baffle plate 4 is damaged, the water in the through hole 101 will flow out from the gap between the baffle plate 4 and the inner wall of the through hole 101, which will cause uneven water layer thickness or local water shortage under the probe, forming an air gap, thereby causing unstable flaw detection waveform or even no bottom wave phenomenon. Utility Model Content

[0004] (I) The problem to be solved by this utility model is that the first pressure plate in the wear-resistant shoe of the probe of the existing GE ultrasonic flaw detector does not match the shape of the through hole on the wear-resistant shoe of the probe, resulting in poor sealing effect.

[0005] (II) Technical Solution

[0006] A wear-resistant boot for flaw detection includes a wear-resistant boot body, a water baffle, and a pressure plate, wherein the wear-resistant boot body has opposing working and non-working surfaces;

[0007] The wear-resistant boot body has a through hole at each end, and the through hole has a long cross-section; the wear-resistant boot body has a rectangular groove at each end along the first direction, and the rectangular groove is located on the non-working surface of the wear-resistant boot body.

[0008] The rectangular grooves and the through holes correspond one-to-one, and the through holes and the corresponding rectangular grooves are connected.

[0009] The water baffle is sealed inside the through hole and close to the working surface of the wear-resistant boot body;

[0010] The pressure plate includes a first plate and a second plate connected to each other. The shape of the first plate matches the through hole to seal the through hole, and the second plate is locked onto the rectangular groove by countersunk screws.

[0011] According to one embodiment of the present invention, the shape of the second plate body matches the rectangular groove to cover the rectangular groove.

[0012] According to one embodiment of the present invention, each of the rectangular grooves is provided with at least one countersunk hole, and the second plate is provided with a second mounting hole corresponding to each of the countersunk holes.

[0013] According to one embodiment of the present invention, the first plate and the second plate have the same thickness, the thickness of the second plate is 1.5mm-2mm, and the depth of the rectangular groove is consistent with the thickness of the second plate.

[0014] According to one embodiment of the present invention, the first plate and the second plate are integrally formed.

[0015] According to one embodiment of the present invention, the first plate is a long strip plate, and the second plate is a rectangular plate.

[0016] According to one embodiment of the present invention, the rectangular groove is located on one side of the through hole, and the length of the rectangular groove is less than the length of the through hole.

[0017] A flaw detector, including the aforementioned flaw detection wear-resistant boot.

[0018] The beneficial effects of this utility model are:

[0019] Compared with traditional flaw detection abrasion-resistant boots, this flaw detection abrasion-resistant boot has at least the following advantages:

[0020] First, the elongated shape of the second pressure plate perfectly matches the cross-section of the through hole, completely covering and sealing it, eliminating the problem in existing designs where the first pressure plate cannot completely cover the through hole. Because the through hole is completely sealed, coupling water (the medium used for flaw detection) cannot seep into the through hole from the second pressure plate; in other words, only a trace amount of water seeps into the through hole from the second pressure plate. Thus, the baffle plate only needs to handle this trace infiltration (non-active leakage), significantly reducing the load and extending its lifespan.

[0021] Secondly, by effectively sealing the hole, the possibility of coupling water leaking out through the gaps is minimized, ensuring the stability of the water layer and thus ensuring the stability of acoustic wave propagation during the flaw detection process. This directly solves the problems of unstable flaw detection waveforms (such as waveform jitter) or no bottom wave (inability to detect defects at the bottom of the workpiece) caused by water leakage in existing technologies, thus improving the accuracy and reliability of flaw detection.

[0029] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] like Figures 2-5 As shown, one embodiment of the present invention provides a flaw detection wear-resistant boot, including a wear-resistant boot body 1, a water baffle 4 and a pressure plate. The wear-resistant boot body 1 has a working surface and a non-working surface, and the wear-resistant boot body 1 has an assembly cavity 104 for mounting a probe.

[0031] The wear-resistant boot body 1 has a through hole 101 at each end, and the cross-section of the through hole 101 is elongated. The wear-resistant boot body 1 has a rectangular groove 102 at each end along the first direction, and the rectangular groove 102 is located on the non-working surface of the wear-resistant boot body 1. The rectangular groove 102 and the through hole 101 correspond one-to-one, and the through hole 101 and the corresponding rectangular groove 102 are connected. The baffle plate 4 is sealed and installed inside the through hole 101 and close to the working surface of the wear-resistant boot body 1. The pressure plate includes a first plate and a second plate connected to each other. The shape of the first plate matches the through hole 101 to seal the through hole 101, and the second plate is locked onto the rectangular groove 102 by countersunk screws 3.

[0032] It should be noted that the working surface of the wear-resistant boot body 1 is the bottom surface of the wear-resistant boot body 1, and the non-working surface of the wear-resistant boot body 1 is the top surface of the wear-resistant boot body 1. The working surface of the wear-resistant boot body 1 is the surface used to contact the workpiece to be inspected.

[0033] In this embodiment, as Figure 2 and Figure 3 As shown, two through holes 101 are located on the left and right sides of the wear-resistant boot body 1, respectively. The length direction of the two through holes 101 is the same as the width direction of the wear-resistant boot body 1. A rectangular groove 102 is opened on the non-working surface of the wear-resistant boot body 1, and the rectangular groove 102 is located outside the through hole 101. The length of the rectangular groove 102 is less than the length of the through hole 101.

[0034] For convenience and Figure 1 To differentiate between flaw detection and wear-resistant boots, the pressure plate in this application is named the second pressure plate 7. Figure 4 As shown, the second pressure plate 7 includes a first plate and a second plate connected to each other, wherein the outer dimensions of the first plate and the cross-sectional dimensions of the through hole 101 are completely matched.

[0035] After the second pressure plate 7 is fixedly installed onto the rectangular groove 102 using countersunk screws 3, the outer dimensions of the first plate and the cross-sectional dimensions of the through hole 101 are perfectly matched, thus achieving a complete fit between the second pressure plate 7 and the through hole 101, providing excellent sealing performance. This makes it difficult for water to enter the through hole 101, preventing coupling water from flowing out, reducing the burden on the baffle plate 4, and avoiding unstable waveforms in the flaw detection caused by water leakage.

[0036] In this embodiment, combined with Figure 2 and Figure 4 As can be seen, the shape of the second plate matches the rectangular groove 102, so that the second plate of the second pressure plate 7 can completely cover the rectangular groove 102. Each rectangular groove 102 has two countersunk holes 103. The second plate of the second pressure plate 7 has a second mounting hole 703 that corresponds one-to-one with the countersunk hole 103.

[0037] After placing the second pressure plate 7, simply insert the countersunk screw 3 into the second mounting hole 703 on the top surface of the second plate, and then tighten the countersunk screw 3.

[0038] It should be noted that, since the cross-section of the through hole 101 is elongated, and the cross-section of the rectangular groove 102 is rectangular, the first plate of the second pressure plate 7 in this embodiment is an elongated plate 701, and the second plate is a rectangular plate 702. The outer dimensions of the elongated plate 701 are perfectly matched with the through hole 101, and the rectangular plate 702 is perfectly matched with the rectangular groove 102.

[0039] As an alternative embodiment, the outer dimensions of the second plate are smaller than those of the rectangular groove 102, and the second plate partially covers the rectangular groove 102.

[0040] In some embodiments, the elongated plate 701 and the rectangular plate 702 are integrally formed. Figure 4 This is a top view of the second pressure plate 7. The edges of the top surface of the second pressure plate 7 are named sequentially as the first edge 704, the first arc transition 705, the second edge 706, the third edge 707, the fourth edge 708, the fifth edge 709, the sixth edge 710, and the second arc transition 711. The first edge 704, the first arc transition 705, the second edge 706, the third edge 707, the fourth edge 708, the fifth edge 709, the sixth edge 710, and the second arc transition 711 are connected sequentially.

[0041] Among them, the first side 704, the second side 706 and the fourth side 708 are parallel, the second side 706 and the sixth side 710 are on a straight line, the third side 707 is perpendicular to the second side 706, the fifth side 709 is perpendicular to the sixth side 710, the length of the second side 706 is the same as the length of the sixth side 710, the length of the third side 707 is the same as the length of the fifth side 709, the first arc transition 705 and the second arc transition 711 are exactly the same, and the second mounting hole 703 is located between the fifth side 709 and the third side 707.

[0042] Furthermore, the cross-sections of the aforementioned through hole 101 and rectangular groove 102 are perfectly matched with the cross-section of the second pressure plate 7 in this embodiment. That is, in this embodiment, the distance between the first side 704 and the second side 706 is the same as the width of the through hole 101, the distance between the second side 706 and the fourth side 708 is the same as the width of the rectangular groove 102, the length between the first arc transition 705 and the second arc transition 711 is the same as the length of the cross-section of the through hole 101, and the distance between the third side 707 and the fifth side 709 is the same as the length of the rectangular groove 102.

[0043] In some embodiments, the elongated plate 701 and the rectangular plate 702 in the second pressure plate 7 have the same thickness, with the rectangular plate 702 having a thickness of 1.5mm-2mm, preferably 1.5mm. Correspondingly, the depth of the rectangular groove 102 is 1.5mm. It should be noted that the conventional first pressure plate 2 has a thickness of 1.0mm, which results in a short service life due to easy wear. In this embodiment, by increasing the thickness of the second pressure plate 7 to 1.5mm, the service life of the second pressure plate 7 is correspondingly improved.

[0044] In this embodiment, as Figure 5 As shown, a sealing strip 5 is installed on the bottom inner wall of the through hole 101. The water baffle 4 cooperates with the sealing strip 5 to eliminate the gap between the water baffle 4 and the inner wall of the through hole 101, thereby improving the sealing effect.

[0045] In this embodiment, as Figure 2 As shown, the wear-resistant boot body 1 has two inclined plates 6 inside, such as... Figure 3 As shown, wear-resistant strips 9 are fixedly installed on the bottom inclined surfaces of the two inclined plates 6 by mounting screws 8.

[0046] In summary, compared with traditional flaw detection abrasion-resistant boots, the flaw detection abrasion-resistant boot in this embodiment has at least the following advantages:

[0047] First, the elongated strip 701 of the second pressure plate 7 perfectly matches the cross-section of the through hole 101, completely covering and sealing the through hole 101, eliminating the problem in the existing design where the first pressure plate 2 cannot completely cover the through hole 101. Since the through hole 101 is completely sealed, coupling water (the medium used for flaw detection) cannot seep into the interior of the through hole 101 from the second pressure plate 7, or in other words, only a trace amount of water seeps into the through hole 101 from the second pressure plate 7. Thus, the baffle plate 4 only needs to handle the trace amount of seepage (non-active leakage), significantly reducing the load and extending its service life.

[0048] Secondly, through effective sealing, coupling water cannot flow out from the gap in the through hole 101, ensuring the stability of the water layer and thus ensuring the stability of acoustic wave propagation during the flaw detection process. This directly solves the problems of unstable flaw detection waveforms (such as waveform jitter) or no bottom wave (inability to detect defects at the bottom of the workpiece) caused by water leakage in the prior art, improving the accuracy and reliability of flaw detection.

[0049] Another embodiment of this utility model provides a flaw detector, which is a water immersion ultrasonic flaw detector. The water immersion ultrasonic flaw detector includes the aforementioned flaw detection wear-resistant boot and probe, with the probe and flaw detection wear-resistant boot being connected and installed together.
