Description
Technical Field
[0001] This utility model relates to the field of engineering testing technology, and more specifically, to an ultrasonic non-destructive testing instrument that prevents accidental probe movement. Background Technology
[0002] Engineering testing is a series of operations conducted in the fields of building engineering and industrial engineering. It involves detailed inspection and testing of engineering projects to verify the rationality of the design scheme, the compliance of construction quality, and the stability and safety of the engineering structure.
[0003] Especially for some metal components, the welds of these metal components are the most important connection parts in the engineering structure during construction. Their quality directly affects the safety and stability of the entire structure. Defects that may exist in the welds, such as cracks, slag inclusions, and lack of fusion, may become potential hidden dangers for structural failure. Ultrasonic non-destructive testing instruments can use the characteristics of ultrasonic waves propagating and reflecting in materials to achieve accurate detection and evaluation of internal defects in welds.
[0004] Currently, when using ultrasonic non-destructive testing equipment, operators typically inspect the metal surface by placing the probe against it. When a defect is detected, the probe receives ultrasonic feedback, which is then transmitted to the instrument's display screen for the operator to view. At this point, the operator needs to assess the defect. However, in actual use, the probe surface and the metal surface are relatively smooth, making it easy for the probe to slip and become misaligned during assessment. This requires the operator to re-examine the surface, which is time-consuming and labor-intensive. Therefore, improvements and optimizations are needed. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology, this utility model provides an ultrasonic non-destructive testing instrument that prevents accidental probe movement and has the advantage of preventing misalignment and displacement.
[0006] The technical solution of this utility model is as follows: an ultrasonic non-destructive testing instrument to prevent accidental probe movement, comprising an ultrasonic non-destructive testing instrument, a display screen on the front side of the ultrasonic non-destructive testing instrument, a control button on the front side of the ultrasonic non-destructive testing instrument, a connecting line fixedly installed on the top of the ultrasonic non-destructive testing instrument, a probe fixedly installed at the other end of the connecting line, a connecting block sleeved on the top of the probe, and a fixing plate detachably installed on the outer wall of the connecting block;
[0007] Fixed cylinders are fixedly installed at the bottom of the left and right sides of the fixed plate. Expansion grooves are opened inside the left and right sides of the fixed plate. Plugs are movably installed inside the expansion grooves. Fixed blocks are fixedly installed inside the fixed cylinders. Suction cups are fixedly installed at the bottom of the fixed blocks. The suction cups and expansion grooves are interconnected. A screw is rotatably installed inside the expansion groove. The screw and the plug are threaded together. The top of the screw extends through to the top of the fixed plate and is fixedly installed with a knob. The knob is rotatably installed on the top of the fixed plate.
[0008] As a preferred technical solution of this utility model, the probe is threadedly fitted with a probe sleeve on its outer wall, and an anti-wear block is fixedly installed on the bottom outer wall of the probe sleeve. A ball bearing is rotatably installed on the bottom of the anti-wear block, and the ball bearing is circumferentially arranged at the bottom of the anti-wear block.
[0009] In a preferred embodiment of this invention, the probe is movably mounted inside the connecting block, and the top of the probe and the inner wall of the connecting block are elastically connected by a first spring.
[0010] As a preferred embodiment of this utility model, a mating groove is provided in the middle of the fixing plate, and mounting grooves are provided on both the left and right sides of the mating groove, and the shape of the mating groove matches that of the connecting block.
[0011] As a preferred technical solution of this utility model, the connecting block has movable grooves at both ends, and inclined wedges are movably installed inside the two sets of movable grooves.
[0012] As a preferred embodiment of this utility model, the wedge and the inner wall of the movable groove are elastically connected by a second spring, and one end of the wedge and the mounting groove abut against each other.
[0013] As a preferred embodiment of this utility model, a control plate is fixedly installed on the top of the wedge, and the control plate is movably installed on the top of the connecting block.
[0014] As a preferred embodiment of this utility model, one end of the connecting wire extends into the interior of the connecting block, and the connecting wire and the probe are fixedly connected.
[0015] As a preferred embodiment of this utility model, the two sets of movable grooves and mounting grooves are positioned correspondingly, and the inclined surface of the wedge is opened downwards.
[0016] As a preferred technical solution of this utility model, the left and right sides of the inside of the telescopic groove are provided with limiting grooves, and the left and right sides of the outer wall of the plug are provided with protrusions that match the limiting grooves.
[0017] The working principle and beneficial effects of this utility model are as follows:
[0018] 1. This utility model, through the setting of the fixing plate, allows the operator to rotate the knob to move the plug upward along the telescopic groove when the suction cup is attached to the surface of the metal part, further adhering the suction cup to the surface of the metal part and preventing the probe from shaking or shifting. After the inspection is completed, the connecting block and the fixing plate can be removed by pushing the two sets of control plates. Compared with traditional devices, this device can not only perform inspections by the probe alone, but also fix the probe to the surface of the metal part by installing the fixing plate when it is necessary. This greatly facilitates the inspection and flaw detection work of the operator and reduces the workload.
[0019] 2. After the fixing plate is installed, the first spring ensures that the ball bearing at the bottom of the anti-wear block will always be in contact with the surface of the metal part to be tested. At the same time, when the probe needs to be moved, the ball bearing will change the sliding friction of the probe into the rolling friction of the ball bearing, preventing the probe end from wearing after long-term detection operations and ensuring the service life of the device.

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0029] like Figures 1 to 6 As shown, this utility model provides an ultrasonic non-destructive testing instrument to prevent accidental probe movement, including an ultrasonic non-destructive testing instrument 1, a display screen 2 on the front side of the ultrasonic non-destructive testing instrument 1, a control button 3 on the front side of the ultrasonic non-destructive testing instrument 1, a connecting line 4 fixedly installed on the top of the ultrasonic non-destructive testing instrument 1, a probe 5 fixedly installed on the other end of the connecting line 4, a connecting block 6 sleeved on the top of the probe 5, and a fixing plate 7 detachably installed on the outer wall of the connecting block 6.
[0030] Fixed cylinders 8 are fixedly installed at the bottom of the left and right sides of the fixed plate 7. Expansion grooves 9 are opened inside the left and right sides of the fixed plate 7. A plug 11 is movably installed inside the expansion groove 9. A fixed block 14 is fixedly installed inside the fixed cylinder 8. A suction cup 24 is fixedly installed at the bottom of the fixed block 14. The suction cup 24 and the expansion groove 9 are interconnected. A screw 12 is rotatably installed inside the expansion groove 9. The screw 12 and the plug 11 are threaded together. The top of the screw 12 extends through to the top of the fixed plate 7 and a knob 13 is fixedly installed thereon. The knob 13 is rotatably installed on the top of the fixed plate 7.
[0031] When inspecting the welded metal structure, the operator places the probe 5 against the surface of the metal part and adjusts the position of the probe 5 to perform non-destructive testing. If an anomaly is detected, the operator places two sets of suction cups 24 against the surface of the metal part and rotates the knob 13 to rotate the screw 12. The rotation of the screw 12 causes the plug 11, which is threaded onto it, to move upward along the limiting groove 10. Further upward movement of the plug 11, due to the contact between the suction cups 24 and the surface of the metal part, allows the plug 11 to remove air from between the suction cups 24 and the metal part, further adsorbing the fixing plate 7 onto the surface of the metal part, preventing... To prevent the probe 5 from shaking, the probe 5 will move downwards by the elastic potential energy of the first spring 17, ensuring that the bottom of the probe 5 and the surface of the metal part are in contact. When the probe 5 does not need to be fixed, the operator reverses the knob 13 to remove the fixing plate 7, and then pushes the two sets of control plates 20 inward. It is worth noting that the distance between the two sets of control plates 20 is relatively narrow, and the operator can push them with one hand. At this time, the two sets of wedges 18 are stored inside the movable groove 16, and the fixing relationship between the fixing plate 7 and the connecting block 6 is canceled, so that the fixing plate 7 can be removed, realizing the modular disassembly between the probe 5 and the fixing plate 7.
[0032] With the setting of the fixing plate 7, when the suction cup 24 is in contact with the surface of the metal part, the operator can rotate the knob 13 to move the plug 11 upward along the telescopic groove 9, further adhering the suction cup 24 to the surface of the metal part, preventing the probe 5 from shaking or shifting. After the inspection is completed, the connecting block 6 and the fixing plate 7 can be removed by pushing the two sets of control plates 20. Compared with the traditional device, this device can not only perform inspection by the probe 5 alone, but also fix the probe 5 to the surface of the metal part by installing the fixing plate 7 when it is necessary to fix the probe 5. This greatly facilitates the inspection and flaw detection work of the operator and reduces the workload.
[0033] The probe 5 is threaded with a probe sleeve 21, and an anti-wear block 22 is fixedly installed on the bottom outer wall of the probe sleeve 21. A ball bearing 23 is rotatably installed on the bottom of the anti-wear block 22. The ball bearing 23 is circumferentially arranged on the bottom of the anti-wear block 22.
[0034] After the fixing plate 7 is fixed, the probe 5 will always be subjected to a downward force through the elastic potential energy of the first spring 17. Furthermore, the ball 23 at the bottom of the anti-wear block 22 will always be in contact with the surface of the metal part to be tested. When the operator needs to move the probe 5, the ball 23 will slide on the surface of the metal part, further preventing wear caused by friction between the probe 5 and the surface of the metal part.
[0035] After the fixing plate 7 is installed, the first spring 17 ensures that the ball bearing 23 at the bottom of the anti-wear block 22 will always be in contact with the surface of the metal part to be tested. At the same time, when the probe 5 needs to be moved, the ball bearing 23 will change the sliding friction of the probe 5 into the rolling friction of the ball bearing 23, preventing the probe end of the probe 5 from wearing out after long-term detection operations and ensuring the service life of the device.
[0036] The probe 5 is movably installed inside the connecting block 6, and the top of the probe 5 and the inner wall of the connecting block 6 are elastically connected by the first spring 17.
[0037] The probe 5 will be displaced downward by the elastic potential energy of the first spring 17, ensuring that the bottom of the probe 5 and the surface of the metal part are in contact with each other.
[0038] The fixing plate 7 has a mating groove 25 in the middle, and mounting grooves 15 are provided on both the left and right sides of the mating groove 25. The mating groove 25 and the connecting block 6 are matched in shape.
[0039] The docking slot 25 facilitates the positioning of the connecting block 6 and the fixing plate 7 when they are docked.
[0040] The connecting block 6 has movable grooves 16 at both ends, and wedges 18 are movably installed inside the two sets of movable grooves 16.
[0041] The wedge 18 and the inner wall of the movable groove 16 are elastically connected by a second spring 19, and one end of the wedge 18 abuts against the mounting groove 15.
[0042] The wedge 18 and the mounting groove 15 abut against each other to complete the docking installation between the connecting block 6 and the fixing plate 7.
[0043] Among them, the top of the wedge 18 is fixedly installed with a control plate 20, and the control plate 20 is movably installed on the top of the connecting block 6.
[0044] When it is necessary to install between the connecting block 6 and the fixing plate 7, the worker inserts the connecting block 6 into the inside of the docking groove 25. At this time, the control plate 20 will be squeezed into the inside of the movable groove 16 by the outer wall of the docking groove 25.
[0045] One end of the connecting wire 4 extends into the interior of the connecting block 6, and the connecting wire 4 and the probe 5 are fixedly connected.
[0046] Among them, the two sets of movable grooves 16 and mounting grooves 15 are positioned correspondingly, and the inclined surface of the wedge 18 is opened downward.
[0047] After the connecting block 6 is fully installed, the movable groove 16 and the mounting groove 15 are aligned with each other, and the wedge 18 will enter the interior of the mounting groove 15 through the elastic potential energy of the second spring 19, thus completing the installation.
[0048] The expansion groove 9 has limit grooves 10 on both the left and right sides, and the plug 11 has protrusions on both the left and right sides that match the limit grooves 10.
[0049] By setting two sets of limiting grooves 10, the plug 11 can only move up and down inside the expansion groove 9, preventing misalignment.
[0050] Working principle and usage process of this utility model:
[0051] When inspecting the welded metal structure, the operator places the probe 5 against the surface of the metal part and adjusts the position of the probe 5 to perform non-destructive testing. If an anomaly is detected, the operator places two sets of suction cups 24 against the surface of the metal part and rotates the knob 13 to rotate the screw 12. The rotation of the screw 12 causes the plug 11, which is threaded onto it, to move upward along the limiting groove 10. Further upward movement of the plug 11, due to the contact between the suction cups 24 and the surface of the metal part, allows the plug 11 to remove air from between the suction cups 24 and the metal part, further adsorbing the fixing plate 7 onto the surface of the metal part, preventing... To prevent the probe 5 from shaking, the probe 5 will move downwards by the elastic potential energy of the first spring 17, ensuring that the bottom of the probe 5 and the surface of the metal part are in contact. When the probe 5 does not need to be fixed, the operator reverses the knob 13 to remove the fixing plate 7, and then pushes the two sets of control plates 20 inward. It is worth noting that the distance between the two sets of control plates 20 is relatively narrow, and the operator can push them with one hand. At this time, the two sets of wedges 18 are stored inside the movable groove 16, and the fixing relationship between the fixing plate 7 and the connecting block 6 is canceled, so that the fixing plate 7 can be removed, realizing the modular disassembly between the probe 5 and the fixing plate 7.
[0052] After the fixing plate 7 is fixed, the probe 5 will always be subjected to a downward force through the elastic potential energy of the first spring 17. Furthermore, the ball 23 at the bottom of the anti-wear block 22 will always be in contact with the surface of the metal part to be tested. When the operator needs to move the probe 5, the ball 23 will slide on the surface of the metal part, further preventing wear caused by friction between the probe 5 and the surface of the metal part.
[0053] The above are merely preferred embodiments of the present utility model and are 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 shall be included within the protection scope of the present utility model.
