Description

Technical Field

[0001] This invention relates to the field of ultrasonic testing technology, specifically to a defect detection device for wear-resistant steel lining plates based on ultrasonic sensors. Background Technology

[0002] The wear-resistant steel liner defect detection device based on ultrasonic sensors aims to detect defects such as cracks, voids, and peeling in wear-resistant steel liners using ultrasonic technology.

[0003] Patent publication number CN211741162U relates to a defect detection device for finished wind turbine blades, including an operating table, a controller, a detection instrument, a flipping clamping mechanism, and a translation mechanism. The flipping clamping mechanism is located at both ends of the operating table, and the translation mechanism is located along the axis of the operating table. The detection instrument is mounted on the translation mechanism and can move along it. The detection instrument includes a signal transmitter and an ultrasonic probe. The output of the controller is connected to the signal transmitter, and the output of the ultrasonic probe is connected to the input of the controller. The flipping clamping mechanism is located at both ends of the operating table and is used to clamp the wind turbine blades and enable the blades to flip. Driven by the translation mechanism, the ultrasonic probe can scan and detect the blades. Moreover, the blades can be flipped to scan and detect other surfaces. By using the ultrasonic probe to perform multi-angle overall scanning of the wind turbine blades, manual inspection is not required, making the size acquisition of the wind turbine blades more accurate.

[0004] In the aforementioned patent, the wind turbine blades are scanned from multiple angles using an ultrasonic probe, eliminating the need for manual inspection and making the size acquisition of the wind turbine blades more accurate. However, when inspecting the steel liner, ultrasonic testing should be performed as close to the steel liner as possible. Excessive distance will lead to errors in the test results and affect the reliability of the measurement results. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a defect detection device for wear-resistant steel lining plates based on ultrasonic sensors, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a defect detection device for wear-resistant steel lining plates based on an ultrasonic sensor, comprising an operating table, wherein a guide rail is fixedly installed on the top of the operating table;

[0007] A driving device is disposed on the top of the guide rail, and the driving device is used to drive the driving device to reciprocate on the top of the guide rail;

[0008] A support frame is fixedly installed on the top of the drive device, and hollow tubes are fixedly installed between the support frames. A cylinder is slidably installed on the top of the hollow tube, a long plate is fixedly installed on the bottom of the cylinder, and a hydraulic device is provided on the top of the cylinder.

[0009] An ultrasonic probe is located at the bottom of a long plate and is used to perform ultrasonic testing on items placed on top of the workbench.

[0010] A housing is fixedly installed on the top of the long plate, a lifting block slides through the surface of the long plate, a detection roller is rotatably installed on the bottom of the lifting block, an inclined block is slidably installed inside the housing, a groove is opened on the surface of the inclined block, a sliding block is fixedly installed on the top of the lifting block, and the sliding block is slidably installed on the inner wall of the groove.

[0011] According to the above technical solution, a lifting vertical rod is slidably installed on the top of the long plate, and a fixing block is fixedly installed on the surface of the lifting vertical rod. A limit block is rotatably installed on the side of the fixing block away from the lifting vertical rod. The driving device moves to drive the support frame and hollow tube to move towards the tail of the steel liner. Then, the ultrasonic probe performs ultrasonic testing on the steel liner, so that the ultrasonic probe is as close to the steel liner as possible during the test. A limit plate is fixedly installed at the bottom of the fixing block. After the long plate moves, the testing roller no longer contacts the steel liner. Then, the lifting vertical rod moves to the bottom, driving the fixing block to the bottom. The movement of the fixing block drives the limit block to the bottom. Since the limit block is no longer blocked by the limit plate, the top of the operating table is equipped with a protective device to improve the reliability of the steel liner test results and a noise reduction device to reduce test errors.

[0012] According to the above technical solution, a No. 1 spring is provided between the lifting block and the long plate, and the limiting block is in contact with the hollow tube. When the detection roller does not contact the steel liner plate, the No. 1 spring drives the lifting block to reset.

[0013] According to the above technical solution, a second spring is provided between the lifting vertical rod and the housing. The inclined block is in contact with the lifting vertical rod, and the second spring drives the lifting vertical rod to reset when the inclined block is no longer in contact with the lifting vertical rod.

[0014] According to the above technical solution, the protective device includes: a transmission rod, a rotating rod, a transmission plate, a collar, a through rod, a limiting rod, and a stop block. The transmission rod is slidably installed on the inner wall of the hollow tube and is fixedly connected to the lifting vertical rod. The rotating rod is rotatably installed on the bottom of the inner wall of the support frame. A spiral groove is formed on the circumferential surface of the rotating rod. One end of the transmission plate is fixedly installed on the end of the transmission rod away from the lifting vertical rod, and the other end of the transmission plate is rotatably installed on the circumferential surface of the rotating rod. The collar is slidably installed on the inner wall of the spiral groove. The through rod slides through the surface of the support frame and is fixedly connected to the collar. The movement of the through rod drives the limiting rod to move to the top. After the limiting rod moves, it no longer contacts the stop block and is no longer obstructed. The limiting rod is fixedly installed on the end of the through rod away from the collar. The stop block is fixedly installed on the top of the operating table. The movement of the through rod drives the limiting rod to move to the bottom. After the limiting rod moves, it contacts the stop block.

[0015] According to the above technical solution, a torsion spring is provided between the rotating rod and the support frame, and the limiting rod contacts the abutment block. The torsion spring drives the rotating rod to reset when the transmission rod no longer contacts the lifting vertical rod.

[0016] According to the above technical solution, the silencing device includes: a lifting slider, a silencing roller, a rotating plate, a rotating shaft, a rotating push rod, and a rubber ring. A square groove is provided at the bottom of the driving device. The lifting slider is slidably mounted on the inner wall of the square groove. The silencing roller is rotatably mounted on the inner wall of the lifting slider. Sound-absorbing cotton is installed inside the silencing roller. When the driving device moves, the sound-absorbing cotton absorbs the noise generated during movement, thus reducing the noise. The rotating plate is rotatably mounted on the inner wall of the driving device. One end of the rotating plate is rotatably mounted on the top of the lifting slider, and the other end is rotatably mounted on the surface of the limiting rod. The rotating shaft is fixedly mounted inside the silencing roller. The rotating push rod is rotatably mounted on the circumferential surface of the rotating shaft. The rubber ring is slidably mounted on the circumferential surface of the rotating shaft. When the rubber ring moves, it contacts the lifting slider, causing excessive friction between the lifting slider and the silencing roller, thus reducing the rotational speed of the silencing roller.

[0017] According to the above technical solution, a second torsion spring is provided between the rotating push rod and the rotating shaft, the rotating push rod is in contact with the rubber ring, and a third spring is provided between the rubber ring and the rotating shaft. The second torsion spring drives the rotating push rod to reset when it stops rotating.

[0018] This invention provides a defect detection device for wear-resistant steel lining plates based on an ultrasonic sensor. It has the following beneficial effects:

[0019] (1) In this invention, the support frame and hollow tube are moved to the tail of the steel liner by the moving drive device. Then the ultrasonic probe performs ultrasonic testing on the steel liner. During the test, the ultrasonic probe is as close to the steel liner as possible to prevent the signal reflection from being incomplete due to the distance, which would affect the accuracy of the test results and ensure the reliability of the measurement results. After the long plate moves, the test roller no longer contacts the steel liner. Then the lifting rod moves to the bottom and drives the fixed block to the bottom. The movement of the fixed block drives the limiting block to the bottom. Since the limiting block is no longer blocked by the limiting plate, the device can automatically reset after the test is completed, which improves the comfort of using the device.

[0020] (2) In this invention, the movement of the through rod drives the limiting rod to move to the top. After the limiting rod moves, it no longer contacts the stop block and is no longer blocked, so that the ultrasonic probe of the device cannot be tested before the adjustment is completed, thus further ensuring the reliability of the measurement data. The movement of the through rod drives the limiting rod to move to the bottom. After the limiting rod moves, it contacts the stop block, so that the device will automatically limit and release the limit according to the working state of the ultrasonic probe, thereby improving the automation level of the device.

[0021] (3) The invention reduces noise generated during movement by absorbing sound-absorbing cotton when the drive device moves, thereby preventing excessive noise from interfering with or distorting the detection signal and ensuring the normal operation of the entire device. The movement of the rubber ring will contact the lifting slider, causing excessive friction between the lifting slider and the silent roller, reducing the rotation speed of the silent roller. This allows the device to automatically slow down when the drive device moves too fast, further reducing the noise generated during movement and improving the practicality of the device.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-4 One embodiment of the present invention is: a defect detection device for wear-resistant steel lining plate based on ultrasonic sensor, including an operating table 1, and a guide rail 2 fixedly installed on the top of the operating table 1;

[0032] Drive device 3 is located on top of guide rail 2 and is used to drive drive device 3 to reciprocate on top of guide rail 2.

[0033] A support frame 4 is fixedly installed on the top of the drive device 3. A hollow tube 5 is fixedly installed between the support frames 4. A cylinder 6 slides on the top and bottom of the hollow tube 5. A long plate 7 is fixedly installed on the bottom of the cylinder 6. A hydraulic device is provided on the top of the cylinder 6. The hydraulic device is used to drive the cylinder 6 to move up and down.

[0034] Ultrasonic probe 8 is located at the bottom of the long plate 7 and is used to perform ultrasonic testing on items placed on top of the operating table 1.

[0035] A housing 9 is fixedly installed on the top of the long plate 7. A lifting block 10 slides through the surface of the long plate 7. A detection roller 11 is rotatably installed on the bottom of the lifting block 10. An inclined block 12 is slidably installed inside the housing 9. A groove is opened on the surface of the inclined block 12. A sliding block 13 is fixedly installed on the top of the lifting block 10. The sliding block 13 is slidably installed on the inner wall of the groove.

[0036] A lifting rod 14 is slidably installed on the top of the long plate 7. A fixing block 15 is fixedly installed on the surface of the lifting rod 14. A limit block 16 is rotatably installed on the side of the fixing block 15 away from the lifting rod 14 to prevent incomplete signal reflection due to excessive distance, thereby affecting the accuracy of the detection results and ensuring the reliability of the measurement results. A limit plate 17 is fixedly installed on the bottom of the fixing block 15 so that the device can automatically reset after the detection is completed, improving the comfort of using the device.

[0037] A first spring is provided between the lifting block 10 and the long plate 7. The limit block 16 is in contact with the hollow tube 5. The first spring drives the lifting block 10 to reset when the detection roller 11 is not in contact with the steel liner.

[0038] A second spring is installed between the lifting rod 14 and the housing 9. The inclined block 12 is in contact with the lifting rod 14. When the inclined block 12 is no longer in contact with the lifting rod 14, the second spring drives the lifting rod 14 to reset.

[0039] In this embodiment, during operation: the steel liner to be tested is placed on top of the operating table 1. The hydraulic device drives the cylinder 6 downwards, which in turn drives the long plate 7 downwards. The long plate 7 downwards drives the lifting block 10 downwards, which in turn drives the testing roller 11 downwards. The testing roller 11, moving downwards, contacts the steel liner. After being blocked, the testing roller 11 moves upwards, driving the lifting block 10 upwards. The lifting block 10 then drives the sliding block 13 to slide into the groove. The sliding block 13 then drives the inclined block 12 towards the cylinder 6, which in turn drives the lifting vertical rod 14 towards the cylinder 6. The lifting vertical rod 14 then drives the fixing block 15 towards the cylinder 6, which in turn drives the limiting block 16 towards the cylinder 6. After block 16 moves, it gets stuck inside the hollow tube 5, limiting the overall device. Then, the drive device 3 is activated, which moves the support frame 4 and the hollow tube 5 towards the tail of the steel liner. Then, the ultrasonic probe 8 performs ultrasonic testing on the steel liner. During the test, the ultrasonic probe 8 is brought as close to the steel liner as possible to prevent incomplete signal reflection due to excessive distance, which would affect the accuracy of the test results and ensure the reliability of the measurement results. The cylinder 6 moves to the top, which moves the long plate 7 to the top. After the long plate 7 moves, the testing roller 11 is no longer in contact with the steel liner. Then, the lifting rod 14 moves to the bottom, which moves the fixing block 15 to the bottom. The movement of the fixing block 15 moves the limiting block 16 to the bottom. Since the limiting block 16 is no longer blocked by the limiting plate 17, the device can automatically reset after the test is completed, improving the comfort of using the device.

[0040] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, the top of the operating table 1 is provided with a protective device for improving the reliability of the steel lining plate detection results and a noise reduction device for reducing detection errors. The protective device includes: a transmission rod 181, a rotating rod 182, a transmission plate 183, a collar 184, a through rod 185, a limiting rod 186, and a stop block 187. The transmission rod 181 is slidably installed on the inner wall of the hollow tube 5 and is fixedly connected to the lifting vertical rod 14. The rotating rod 182 is rotatably installed on the bottom of the inner wall of the support frame 4. A spiral groove is formed on the circumferential surface of the rotating rod 182. One end of the transmission plate 183 is fixedly installed on the transmission rod 184. One end of the transmission plate 183, away from the lifting vertical rod 14, is rotatably mounted on the circumferential surface of the rotating rod 182. The collar 184 is slidably mounted on the inner wall of the spiral groove. The through rod 185 slides through the surface of the support frame 4. The through rod 185 is fixedly connected to the collar 184, so that the ultrasonic probe 8 cannot be tested before the device is adjusted, further ensuring the reliability of the measurement data. The limit rod 186 is fixedly mounted on the end of the through rod 185 away from the collar 184. The stop block 187 is fixedly mounted on the top of the operating table 1, so that the device will automatically limit and release the limit according to the working status of the ultrasonic probe 8, improving the automation level of the device.

[0041] A torsion spring is provided between the rotating rod 182 and the support frame 4. The limiting rod 186 contacts the stop block 187. The torsion spring drives the rotating rod 182 to reset when the transmission rod 181 no longer contacts the lifting vertical rod 14.

[0042] The silencing device includes: a lifting slider 191, a silencing roller 192, a rotating plate 193, a rotating shaft 194, a rotating push rod 195, and a rubber ring 196. A square groove is provided at the bottom of the drive device 3. The lifting slider 191 is slidably mounted on the inner wall of the square groove. The silencing roller 192 is rotatably mounted on the inner wall of the lifting slider 191. Sound-absorbing cotton is installed inside the silencing roller 192 to prevent excessive noise from interfering with or distorting the detection signal, ensuring the normal operation of the entire device. The rotating plate 193 is rotatably mounted on the drive device 3. On the inner wall of device 3, one end of the rotating plate 193 is rotatably mounted on the top of the lifting slider 191, and the other end of the rotating plate 193 is rotatably mounted on the surface of the limit rod 186. The rotating shaft 194 is fixedly mounted inside the silent roller 192. The rotating push rod 195 is rotatably mounted on the circumferential surface of the rotating shaft 194. The rubber ring 196 is slidably mounted on the circumferential surface of the rotating shaft 194, so that the device will automatically reduce the speed when the moving speed of the driving device 3 is too fast, further reducing the noise generated during movement and improving the practicality of the device.

[0043] A second torsion spring is provided between the rotating push rod 195 and the rotating shaft 194. The rotating push rod 195 contacts the rubber ring 196. A third spring is provided between the rubber ring 196 and the rotating shaft 194. The second torsion spring drives the rotating push rod 195 to reset when it stops rotating.

[0044] In this embodiment, during operation: the lifting vertical rod 14 moves, causing the transmission rod 181 to move towards the cylinder 6; the transmission rod 181 moves, causing the transmission plate 183 to move towards the cylinder 6; the transmission plate 183 moves, causing the rotating rod 182 to rotate; the rotating rod 182 rotates, causing the collar 184 to move upwards; the collar 184 moves upwards, causing the through rod 185 to move upwards; the through rod 185 moves, causing the limiting rod 186 to move upwards; after the limiting rod 186 moves, it no longer contacts the abutment block 187, and the limiting rod 186 is no longer obstructed, allowing the ultrasonic probe 8 of the device to move upwards. Before the adjustment is completed, testing cannot be performed. To further ensure the reliability of the measurement data, when the lifting rod 14 is reset by the second spring, the rotating rod 182 is reset by the first torsion spring. The rotation of the rotating rod 182 drives the collar 184 to move to the bottom. The movement of the collar 184 to the bottom drives the through rod 185 to move to the bottom. The movement of the through rod 185 drives the limiting rod 186 to move to the bottom. After the limiting rod 186 moves, it contacts the stop block 187, so that the device will automatically limit and release the limit according to the working status of the ultrasonic probe 8, thereby improving the automation level of the device.

[0045] The limit rod 186 moves upward, causing the rotating plate 193 to rotate. The rotation of the rotating plate 193 causes the lifting slider 191 to move downward. The movement of the lifting slider 191 causes the silent roller 192 to move downward and contact the operating table 1. This allows the sound-absorbing cotton to absorb the noise generated during the movement of the drive device 3, reducing the noise and preventing excessive noise from interfering with or distorting the detection signal, thus ensuring the normal operation of the entire device. The rotation of the silent roller 192 causes the rotating shaft 194 to rotate. When the silent roller 192 rotates too fast, the rotating shaft 194 generates sufficient centrifugal force, causing the rotating push rod 195 to move towards the rubber ring 196. The rubber ring 196 then contacts the lifting slider 191, causing excessive friction between the lifting slider 191 and the silent roller 192, thus reducing the rotation speed of the silent roller 192. This allows the device to automatically slow down when the drive device 3 moves too fast, further reducing the noise generated during movement and improving the practicality of the device.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
