Description

Technical Field

[0001] The utility model relates to the technical field of detection probes, in particular to an ultrasonic scanning device and an ultrasonic probe clamping device thereof. Background Art

[0002] Ultrasonic testing is a non-destructive testing method in which ultrasonic probes emit ultrasonic waves that are transmitted to the equipment under test through a coupling medium, and finally the continuity and integrity of the equipment under test are determined by analyzing the signals on the ultrasonic instrument. Ultrasonic testing is almost always used in the testing of pressure boundaries of pressure vessels such as pressure vessels, nuclear power plant main equipment, power plant boilers, etc. One of the important factors of ultrasonic testing is that the ultrasonic probe must fit tightly to the surface of the equipment under test, and a certain probe clamping force must be provided to ensure the fit and adapt to the position error caused by the manufacturing and installation of the equipment under test. If the fit is poor, it may lead to false detection or missed detection, which will have an adverse effect on the test results and increase the safety risks of the equipment.

[0003] The existing ultrasonic probe clamping device has poor self-adaptation ability and cannot be self-adaptive adjusted to the curved surface of a large-diameter container, which makes it easy to generate errors during the detection process. Utility Model Content

[0037] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.

[0038] The terms "connected" and "connected" used herein may mean directly connected or indirectly connected; "plurality" means two or more. "First" and "second" are only used to distinguish different components and should not be understood as implying relative importance or the number of components.

[0039] Figure 1 and Figure 2 An ultrasonic probe clamping device 1 in an embodiment of the utility model is shown. The ultrasonic probe clamping device 1 is used to install an ultrasonic probe 2 and is carried on a scanner. Together with the scanner, the ultrasonic probe 2 is used to perform ultrasonic scanning of welds and other locations under a narrow annular cavity.

[0040] The ultrasonic probe clamping device 1 comprises a base 10 and at least one clamping module 20, wherein the base 10 is detachably mounted on the scanner and used to install the clamping module 20. The clamping module 20 is detachably mounted on the base 10 and can rotate at a small angle relative to the base 10 to adapt to the structure of the large-diameter arc-surface annular cavity. During the movement of the scanner, the clamping module 20 rotates and adjusts in accordance with the changes in the surface of the device under test, thereby ensuring that the ultrasonic probe 2 is always in a state of surface contact with the device under test.

[0041] Specifically, Figure 3 and Figure 5As shown, at least one first rotating shaft hole 112 is formed on the base 10, and the clamping module 20 includes a mounting seat assembly 21. The mounting seat assembly 21 includes a seat body 211 and a rotating shaft 212. A second rotating shaft hole 2111 is formed on the seat body 211. The rotating shaft 212 is simultaneously penetrated in the first rotating shaft hole 112 and the second rotating shaft hole 2111, so that the base 10 and the clamping module 20 are rotatably connected.

[0042] In some embodiments, the number of the clamping modules 20 and the first shaft holes 112 corresponds to each other, and can be at least two, so that the ultrasonic probe clamping device 1 can be loaded with multiple ultrasonic probes of different angles, and ultrasonic probes of different angles such as 0°, 45°, 60°, 70°, etc. can be arbitrarily combined through the device to improve the detection efficiency. Specifically, the first shaft holes 112 on the base 10 are arranged in a straight line and evenly spaced, and the clamping modules 20 are arranged on the first shaft holes 112 in a one-to-one correspondence.

[0043] For example Figure 1 and Figure 3 As shown, in this embodiment, the number of the clamping modules 20 and the number of the first shaft holes 112 are both three. The three first shaft holes 112 are evenly spaced, and the three clamping modules 20 correspond to the three first shaft holes 112 one by one.

[0044] The base 10 includes a body 11 and a connecting plate 12. The body 11 is longitudinally arranged and used to install the clamping module 20. The first rotating shaft hole 112 vertically penetrates the body 11 up and down. The connecting plate 12 is arranged on one side of the lower end surface of the body 11, and is used to cooperate with the body 11 and be detachably connected to the scanner.

[0045] Specifically, the upper end surface of the body 11 is recessed downward to form a longitudinal receiving groove 111, and the three clamping modules 20 are sequentially installed in the receiving groove 111. The three first rotating shaft holes 112 all penetrate downward from the lower end surface of the receiving groove 111 to the lower end surface of the body 11.

[0046] In some embodiments, one side of the long axis of the receiving groove 111 is penetrated to facilitate the movement of the clamping module 20. The other side of the long axis of the receiving groove 111 has a wall surface for limiting the rotation angle of the clamping module 20. The first rotating shaft hole 112 is arranged at a position so that when the clamping module 20 is arranged on the main body 11, the side wall surface of the seat body 211 of the mounting seat assembly 21 is arranged parallel to the wall surface of the other side of the long axis of the receiving groove 111. In this embodiment, the spacing distance between the two is 1mm, so that when the clamping module 20 is rotatably connected to the main body 11, the rotation angle of the clamping module 20 is limited, and it can only rotate at a small angle within the limit of 1mm spacing, which can not only rotate to adapt to the error caused by the surface or installation of the device under test, but also avoid the situation of looseness caused by excessive rotation and instability during scanning.

[0047] The accommodating groove 111 is longitudinally arranged, and in this embodiment is rectangular. In other optional embodiments, the accommodating groove 111 can also be in an elliptical shape, a racetrack shape, and the like.

[0048] The body 11 is also formed with at least one first connection hole 113, which passes through the body 11 vertically up and down, and can be detachably connected to the scanner in the vertical direction by a connection member such as a screw. Specifically, the number of the first connection holes 113 in this embodiment is two, and the two first connection holes 113 are respectively formed on the side walls at both ends of the long axis of the accommodating groove 111.

[0049] The connecting plate 12 is in the shape of a longitudinally long plate, and its long side is connected to the long side of the lower end surface of the body 11, and the connecting plate 12 is vertically arranged on the lower end surface of the body 11, so that the connecting plate 12 and the body 11 define a right angle structure, which is used to correspond to the mounting portion on the scanner. The connecting plate 12 also has at least one second connecting hole 121 horizontally penetrated along the thickness direction, which is used to be detachably connected to the scanner in the horizontal direction. In this embodiment, the number of the second connecting holes 121 is also two.

[0050] In some embodiments, the first connection hole 113 and the second connection hole 121 are both stepped holes for accommodating a larger head of a bolt. In some other optional embodiments, the first connection hole 113 and the second connection hole 121 may not be provided, and the body 11 may be mounted on the scanner by welding or the like.

[0051] In some embodiments, one end of the lower end surface of the main body 11 is also provided with an inclined surface (not shown in the figure), which is used to cooperate with the inclined structure at a position corresponding to the scanner, so that the main body 11 is fitted with the installation part on the scanner to improve the stability of the installation.

[0052] like Figures 4 to 6As shown, the clamping module 20 includes a probe mounting frame assembly 22 and two stretching elastic members 23 in addition to the mounting seat assembly 21. The mounting seat assembly 21 is rotatably arranged on the body 11 for carrying the probe mounting frame assembly 22. The probe mounting frame assembly 22 is movably arranged on the mounting seat assembly 21 for mounting the ultrasonic probe 2. The two ends of the stretching elastic member 23 are respectively connected to the seat body 211 of the mounting seat assembly 21 and the components on the probe mounting frame assembly 22, and are used to provide tension for the probe mounting frame assembly 22. After the probe mounting frame assembly 22 is pushed by the scanner and the device under test and moves relative to the mounting seat assembly 21, the ultrasonic probe 2 and the device under test are squeezed against each other, and then the ultrasonic probe 2 on the probe mounting frame assembly 22 obtains the pressing force applied to the device under test, and fits tightly with the device under test, ensuring the accuracy of the detection.

[0053] like Figure 5 and Figure 6 As shown, the mounting seat 21 includes two retaining rings 213, two first connecting members 214 and a guide rail 215 in addition to the seat body 211 and the rotating shaft 212. The two retaining rings 213 are arranged at the two ends of the rotating shaft 212, and are respectively clamped between the rotating shaft 212 and the seat body 211 and between the rotating shaft 212 and the body 11, and are used to fix the rotating shaft 212 in the first rotating shaft hole 112 and the second rotating shaft hole 2111. The two first connecting members 214 are used to connect the tensile elastic member 23. The guide rail 215 is used to allow the probe mounting frame assembly 22 to be moved back and forth on the mounting seat assembly 21.

[0054] Read also Figure 1 In this embodiment, the seat body 211 is in a cubic shape, so that one side wall is arranged parallel to one side wall of the receiving groove 111 of the main body 11 where the long axis is located. Two first connecting members 214 are symmetrically arranged on the seat body 211, and are respectively used to connect one end of the two stretching elastic members 23. Specifically, the two first connecting members 214 are respectively arranged on two opposite side wall surfaces, and the two opposite side wall surfaces are perpendicular to the side wall surfaces of the seat body 211 and the main body 11 arranged parallel to each other. And the two first connecting members 214 are arranged at corresponding positions on the two side wall surfaces, and are both arranged at one end of the side wall surface in the horizontal direction.

[0055] In this embodiment, the first connecting member 214 is a hexagonal cylindrical head screw, whose hexagonal cylindrical head is used to connect with the stretch elastic member 23, and the seat body 211 is provided with two threaded holes (not shown in the figure) for accommodating the first connecting member 214. In other optional embodiments, the first connecting member 214 can also be a connecting hook or other structure that can be connected with the stretch elastic member 23, and the first connecting member 214 can also be fixed to the seat body 211 by welding, integral molding, etc.

[0056] In some embodiments, the upper end surface of the seat body 211 is further recessed with a groove 2112 for accommodating the guide rail 215. The groove 2112 is longitudinally arranged, and its two opposite ends penetrate through, and the remaining two sides are used to clamp and fix the guide rail 215 to prevent the guide rail 215 from being loosely installed and moving relative to the seat body 211 in the circumferential direction. The second shaft hole 2111 is coaxially arranged with the vertical axis of the seat body 211, and penetrates from the lower end surface of the groove 2112 to the lower end surface of the seat body 211.

[0057] The guide rail 215 is longitudinally arranged, with its lower end portion accommodated in the groove 2112, and its upper end portion is recessed downward to form a longitudinal guide groove 2151, with both ends of the guide groove 2151 passing through, and the probe mounting frame assembly 22 is arranged on the guide rail 215 to move back and forth along the extension direction of the guide groove 2151.

[0058] At least two third connection holes 2113 are also formed on the lower end surface of the groove 2112, and correspondingly, at least two fourth connection holes 2152 are also formed on the upper and lower sides of the guide rail 215. The third connection holes 2113 and the fourth connection holes 2152 are arranged correspondingly, and are used to pass through connecting members such as bolts, and the seat body 211 and the guide rail 215 are detachably connected through the connecting members. In some other optional embodiments, the guide rail 215 and the seat body 211 can also be fixed by welding or other methods.

[0059] In this embodiment, the number of the third connection holes 2113 and the fourth connection holes 2152 are both four, and the four third connection holes 2113 all penetrate from the lower end surface of the groove 2112 to the lower end surface of the seat body 211, and are divided into two groups of two and are respectively arranged on both sides of the second shaft hole 2111. The four fourth connection holes 2152 are respectively arranged on the wall surfaces on both sides of the guide groove 2151 in two groups, and penetrate from the upper end surface of the wall surface to the lower end surface of the guide rail 215.

[0060] In some embodiments, the third connection hole 2113 or the fourth connection hole 2152 is a stepped through hole to facilitate the insertion of connecting parts such as bolts.

[0061] like Figure 7 As shown, both ends of the rotating shaft 212 are respectively provided with an annular groove 2121 for accommodating the retaining ring 213. Figure 8The seat body 211 is also formed with a circular groove on the lower end surface of the groove 2112. The circular groove is located at the end of the second shaft hole 2111 away from the first shaft hole 112 and is coaxially arranged with the second shaft hole 2111 for clamping the retaining ring 213. The inner side of one retaining ring 213 is accommodated in the clamping groove 2121, and the outer side is arranged in the circular groove to limit the axial position of the shaft 212 and prevent it from falling off from the first shaft hole 112 and the second shaft hole 2111. Correspondingly, the body 11 is also provided with a circular groove (not shown in the figure) at the end of the first shaft hole 112 away from the second shaft hole 2111, wherein the inner side of another retaining ring 213 is accommodated in the clamping groove 2121 at the other end of the shaft 212, and the outer side is arranged in the circular groove, so that both ends of the shaft 212 are fixed in the axial direction.

[0062] like Figure 5 and Figure 6 As shown, the probe mounting frame assembly 22 includes a frame body 221, two second connecting members 222 and a slider 223. The frame body 221 is used to place the ultrasonic probe 2. The two second connecting members 222 are both arranged on the frame body 221, and are respectively used to connect the other ends of the two stretching elastic members 23, and cooperate with the first connecting member 214. After the frame body 221 and the seat body 211 move relative to each other, the stretching elastic members 23 are stretched to generate tension. The slider 223 is arranged on the frame body 221 and is accommodated in the guide groove 2151 of the guide rail 215, and is used to slide back and forth relative to the guide rail 215.

[0063] The frame 221 includes a probe accommodating portion 2211 and a connecting portion 2212 . The probe accommodating portion 2211 is used to detachably mount the ultrasonic probe 2 , and the connecting portion 2212 is used to mount the second connecting member 222 and the slider 223 .

[0064] Specifically, the probe accommodating portion 2211 includes a horizontal plate and two vertical plates, and the two vertical plates are respectively vertically arranged on both sides of the horizontal plate, and are used to fix the ultrasonic probe 2 in the circumferential direction. In some embodiments, each vertical plate is triangular. And each vertical plate is penetrated with a fifth connecting hole 2111a along the thickness direction, which is used to be arranged corresponding to the connecting hole on the ultrasonic probe 2, so as to realize detachable connection with the ultrasonic probe 2 through a connecting piece such as a screw. In this embodiment, the horizontal plate is rectangular in this embodiment, and the two vertical plates are both right-angled triangles.

[0065] The slider 223 is longitudinally arranged and its shape matches the shape of the guide groove 2151 of the guide rail 215 , so that the slider 223 is accommodated in the guide groove 2151 and can be moved back and forth along the extension direction of the guide groove 2151 to drive the frame 221 to move back and forth relative to the base 211 .

[0066] In this embodiment, a longitudinal slider receiving groove is formed on the connecting portion 2212 , and the slider 223 is detachably fixed in the slider receiving groove to further stabilize the connection between the slider 223 and the frame 221 .

[0067] The slider 223 has at least one sixth connection hole 2231 extending vertically up and down. Correspondingly, the slider receiving groove of the connecting portion 2212 has at least one seventh connection hole 2212a formed vertically. The seventh connection hole 2212a is arranged corresponding to the sixth connection hole 2231 and is used for connecting members such as screws to pass through, so that the connecting portion 2212 and the slider 223 are detachably fixed. One side of the slider 223 is received in the slider receiving groove, and the other side is received in the guide groove 2151.

[0068] In some other optional embodiments, the connection portion 2212 may not be provided with a slider receiving groove. The slider 223 may also be fixed to the connection portion 2212 by welding, integral molding or other methods.

[0069] In some embodiments, the second connecting member 222 is symmetrically arranged on the two side walls of the connecting portion 2212, and is correspondingly arranged at the ends of the two side walls, and the other ends of the two stretching elastic members 23 are respectively arranged on the two second connecting members 222, so that the two stretching elastic members 23 are respectively fixed on the two sides of the clamping module 20. It should be understood that one end of the second connecting member 222 on the side wall of the connecting portion 2212 is away from the end of the first connecting member 214, so that the stretching elastic member 23 is arranged obliquely.

[0070] In this embodiment, the second connecting member 222 is a hexagonal cylindrical head screw, and two threaded holes are formed at corresponding positions of the connecting portion 2212 for installing the second connecting member 222. The hexagonal cylindrical head of the hexagonal cylindrical head screw is used to fix the other end of the tensile elastic member 23.

[0071] In some other optional embodiments, the first connecting member 214 and the second connecting member 222 may also be other structures such as connecting hooks, and may also be fixed to the seat body 211 and the connecting portion 2212 by other methods such as welding and integral molding.

[0072] In this embodiment, the stretching elastic member 23 is a stretching spring, and there are two of them to ensure the uniformity of the pulling force. The setting angle of the stretching elastic member 23 (the positional relationship between the first connecting member 214 and the second connecting member 222) makes the horizontal component of the pulling force of the stretching elastic member 23 on the probe mounting frame assembly 22 be the pressing force applied by the ultrasonic probe 2 to the device under test, and the vertical component of the pulling force can prevent the ultrasonic probe 2 from tilting during the detection process.

[0073] It should be understood that the above-mentioned “compression force” refers to the pressure in the horizontal direction exerted by the device under test on the ultrasonic probe 2 when the device under test and the ultrasonic probe 2 are squeezed against each other during the process of the ultrasonic probe 2 detecting the device under test.

[0074] By selecting the elastic coefficient of the stretching elastic member 23, the ultrasonic probe 2 can obtain different clamping force magnitudes. That is, by measuring the distance that the slider 223 moves along the guide groove 2151 of the guide rail 215, the specific spring force value is calculated (according to Hooke's law F=kX), and then the clamping force value is obtained. In this embodiment, the range of the clamping force received by the ultrasonic probe 2 is 0-30N.

[0075] The model of the ultrasonic probe 2 can be selected according to actual needs.

[0076] During specific use, it is necessary to first install the ultrasonic probe clamping device 1 on the scanner, and make the ultrasonic probe 2 fit the detection surface of the device under test. By moving the scanner, the scanner and the base 10 and the mounting seat assembly 21 of the ultrasonic probe clamping device 1 are moved relative to the probe mounting frame assembly 22. Since the ultrasonic probe 2 fits the detection surface of the device under test and cannot move further toward the detection surface, the tensile elastic member 23 connected to the probe mounting frame assembly 22 and the mounting seat assembly 21 is stretched to generate tension, so that the ultrasonic probe 2 and the detection surface of the device under test are squeezed against each other to obtain a pressing force to ensure the accuracy of the detection.

[0077] It is important to understand that Figure 1 For example, the above “cannot move further in the radial direction toward the detection surface” means that the surface marked with number 1 of the ultrasonic probe 2 is in contact with the detection surface of the device under test, and the device under test is stationary. The ultrasonic probe 2 cannot move further toward the device under test, and the movement of the scanner causes the ultrasonic probe 2 and the probe mounting frame assembly 22 to move relative to the mounting seat assembly 21 and the base 10, thereby stretching the elastic member 23 to generate tension, so that the ultrasonic probe 2 and the detection surface of the device under test are squeezed against each other to obtain a pressing force.

[0078] Furthermore, during the detection process, the scanner drives the ultrasonic probe clamping device 1 to move along the detection surface. During the movement, the clamping module 20 can generate a small angle adaptive rotation relative to the base 10 and the scanner through the rotating shaft 212 to adapt to the outward contour of the detection surface, so that the ultrasonic probe 2 can flexibly ensure that it fits on the detection surface.

[0079] It should be understood that the above-mentioned “horizontal direction” and “vertical direction” are based on the orientations shown in the drawings of the present application.

[0080] The utility model also constructs an ultrasonic probe scanning device, which includes a scanner and the above-mentioned ultrasonic probe scanning device 1, and the ultrasonic probe scanning device 1 is installed on the scanner. In this embodiment, the ultrasonic probe scanning device 1 is detachably connected to the scanner.

[0081] It is understandable that the above embodiments only express the preferred implementation of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, the above technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should belong to the scope of the claims of the utility model.
