Description

Technical Field

[0001] This application relates to the technical field of concrete testing, and in particular to a non-destructive testing device for concrete. Background Technology

[0002] To test the quality of concrete, it is necessary to test various parameters of the concrete. Most concrete testing methods are destructive testing. However, in order to conduct in-situ testing and reduce damage to the concrete, non-destructive testing technology for concrete has also been greatly developed. Common non-destructive testing methods include ultrasonic testing, impact echo testing, radar testing, infrared imaging, and rebound testing.

[0003] Chinese patent CN222394004U discloses a non-destructive testing device for concrete, including a support base, a lifting component on the support base, a central rotating part rotatably mounted on the upper part of the lifting component, a reciprocating feed component on the central rotating part, an ultrasonic support table on the reciprocating feed component, and several ultrasonic test heads mounted on the ultrasonic support table. However, in actual testing environments, a large amount of dust particles exist. Dust particles adhering to the surface of the test heads can hinder ultrasonic wave transmission and reception, leading to a decrease or distortion of signal strength, indicating a significant deficiency. Utility Model Content

[0004] To reduce the impact of dust particles on testing, this application provides a non-destructive testing device for concrete.

[0005] The concrete non-destructive testing device provided in this application adopts the following technical solution:

[0006] A non-destructive testing device for concrete includes a base, a lifting component on the base, a support frame on the lifting component, a dustproof chamber on the support frame, a testing plate slidably disposed inside the dustproof chamber, a plurality of testing heads detachably connected to the testing plate, a testing hole for the testing heads to extend from the dustproof chamber, a plurality of rubber sheets on the testing hole, one end of each rubber sheet being connected to the testing hole and the other end being suspended in the air, the plurality of rubber sheets together forming a shielding sheet for blocking the testing hole.

[0007] By adopting the above technical solution, the base is equipped with a lifting component to adjust the height to adapt to different testing needs. When testing is required, the sliding testing plate moves the testing head. The testing head extends out of the testing hole to test the concrete. When testing is not required, the sliding testing plate moves the testing head into the dustproof chamber. The dustproof chamber can prevent dust and other impurities from entering and affecting the testing equipment. Multiple rubber sheets form a shield to block the testing hole, preventing dust and debris from entering the dustproof chamber without affecting the normal extension of the testing head. Therefore, this application can reduce the impact of dust particles on testing.

[0008] Preferably, the detection plate has multiple mounting holes along the length of the dustproof chamber, the bottom of the detection head has a mounting plate, and the mounting plate has a mounting post. The mounting post is made of iron, and a magnetic block is embedded in the bottom wall of the mounting hole. The mounting post is inserted into the mounting hole and slides in cooperation with the mounting hole, and the magnetic block attracts the mounting post. By adopting the above technical solution, during installation, the mounting post is inserted into the mounting hole and the magnetic block attracts the mounting post, thereby installing the detection head. When it is necessary to adjust the position of the detection head, the mounting post is pulled out of the mounting hole, so that the mounting post and the magnetic block are separated, thereby disassembling. Preferably, multiple rubber rings are spaced apart on the side wall of the mounting hole. The multiple rubber rings are arranged along the length of the mounting hole, and all the multiple rubber rings are sleeved on the outside of the mounting post. The mounting post presses the rubber rings against the side wall of the mounting hole. By adopting the above technical solution, multiple rubber rings are spaced apart along the length of the mounting hole sidewall and fitted over the mounting post. The mounting post presses the rubber rings against the sidewall of the mounting hole, which further enhances the stability of the connection between the detection head and the detection plate, making the detection head more securely installed and less prone to shaking or falling off. Preferably, the dustproof chamber is equipped with a dust removal duct, which is connected to a first fan via a flexible hose. The dust removal duct is connected to a ring pipe corresponding to each of the multiple detection holes via the first pipe. Multiple air outlet pipes are connected to the ring pipes, and all of the multiple air outlet pipes are oriented towards the center of the ring pipe. The detection head passes through the ring pipe. By adopting the above technical solution, the air force generated by the first fan is transmitted through the dust removal duct, the first pipe, and the ring pipe, and blown out by multiple air outlet pipes facing the detection hole. This can remove dust near the detection hole and prevent dust from affecting the detection effect of the detection head. Furthermore, when the detection head retracts into the dustproof chamber, the air force can blow off the dust attached to the detection head through the ring pipe, reducing the possibility of the detection head bringing dust into the dustproof chamber. During the next detection, the detection head can be dusted again through the ring pipe, reducing the adverse effect of the dust attached to the detection head on the detection effect. Preferably, the top of the dustproof chamber is provided with a fixed frame, and the dust removal duct is rotatably mounted on the fixed frame via a bearing. One end of the dust removal duct is closed, and the other end is connected to one end of the flexible hose via a second pipe. The second pipe is rotatably connected to the dust removal duct. The first pipe is L-shaped and includes a horizontal pipe and a vertical pipe. One end of the horizontal pipe is connected to the dust removal duct, and the other end is connected to the vertical pipe. One end of the vertical pipe is connected to the annular pipe, and the vertical pipe is parallel to the side wall of the dustproof chamber where the detection hole is located.By adopting the above technical solution, a fixed frame is provided on the top of the dustproof chamber. The dust removal duct is rotatably mounted on the fixed frame via bearings, and the second duct is rotatably connected to the dust removal duct, allowing the dust removal duct to be flexibly rotated and its direction adjusted. The first duct is L-shaped, with the vertical tube parallel to the side wall of the dustproof chamber where the detection hole is located. When it is necessary to inspect the concrete wall, the operator can rotate the dust removal duct, which drives the first duct to rotate, and the first duct drives the ring tube to rotate, so that the detection head can fit against the concrete wall for inspection. Preferably, all the air outlet ducts are provided with internal threads, and a sealing post is threadedly connected to the air outlet duct. By adopting the above technical solution, the sealing post can be threadedly connected to the air outlet duct using the internal threads, achieving a seal on the air outlet duct, which can prevent dust and other substances from entering when the air outlet duct is not in use, and at the same time, it is convenient to control the opening and closing of each air outlet duct according to actual needs. Preferably, the side wall of the dustproof chamber is provided with an extension edge, which contacts the top surface of the support frame, and the extension edge is connected to the support frame by bolts. By adopting the above technical solution, the sidewall of the dustproof chamber is provided with an extension edge and connected to the support frame with bolts, which further improves the stability of the connection between the dustproof chamber and the support frame and ensures the stability of the device structure. Preferably, a handwheel is fitted onto one closed end of the dust removal duct. By adopting the above technical solution, a handwheel is fitted onto one closed end of the dust removal duct, which facilitates manual rotation of the dust removal duct by the operator.

[0009] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting a shield made of rubber sheet around the detection hole, dust and other impurities can be prevented from entering the dustproof chamber and affecting the detection head, making the detection results more accurate; 2. The detection head and the detection plate are detachably connected, which facilitates the replacement and maintenance of the detection head and ensures the normal operation of the detection device; 3. Using a dustproof chamber to protect the detection head can prevent the detection head from being corroded by the external environment when not in use, thus extending the service life of the detection head.

[0016] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0017] The technical solutions in the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This application mainly adopts a detection device with a dustproof chamber and a detection plate, which achieves the effect of protecting the detection head, improving detection accuracy and lifespan. The following is a further detailed description of this application.

[0019] This application provides a concrete non-destructive testing device, referring to... Figure 1 , Figure 2 and Figure 3 The device includes a base 1, a lifting component, a support frame 2, a dustproof chamber 3, a detection plate 4, and multiple detection heads 5. The lifting component is mounted on the base 1, and the support frame 2 is connected to the lifting component. The dustproof chamber 3 is mounted on the support frame 2. The dustproof chamber 3 contains a guide rod 6 and a threaded rod 7. A drive motor 8 is mounted on the outer wall of the dustproof chamber 3. The output shaft of the drive motor 8 is coaxially connected to the threaded rod 7. The threaded rod 7 is threadedly connected to the detection plate 4. The guide rod 6 passes through the detection plate 4 and slides in cooperation with the detection plate 4. In use, the drive motor 8 is started, which drives the threaded rod 7 to rotate. Under the guidance of the guide rod 6, the detection plate 4 slides within the dustproof chamber 3.

[0020] Reference Figure 1 , Figure 2 and Figure 4 Multiple detection heads 5 are detachably connected to the detection plate 4. For easy maintenance of the detection heads 5, an operation window 9 is provided on the side wall of the dustproof chamber 3. The operation window 9 is sealed with a rubber plug 10; simply remove the rubber plug 10 to open it. The support frame 2 connects to and supports the dustproof chamber 3, which protects the detection heads 5 from external dust particles and other impurities. The detachable detection heads 5 facilitate subsequent maintenance and replacement.

[0021] Reference Figure 1 , Figure 4 and Figure 5 The detection plate 4 includes a frame and mounting holes 11. The shape of the frame is adapted to the interior of the dustproof chamber 3, allowing it to slide smoothly within the dustproof chamber 3. The mounting holes 11 are provided on the frame along the length of the dustproof chamber 3 for mounting the detection head 5.

[0022] Reference Figure 1 , Figure 4 and Figure 5 In this embodiment, the detection head 5 is an ultrasonic detection head. Ultrasonic detection heads are existing technology and will not be described in detail in this embodiment. The bottom of the detection head 5 is fixedly connected to a mounting plate 12. The mounting plate 12 is provided with a mounting post 13. The mounting post 13 is made of iron. A magnetic block 14 is embedded in the bottom wall of the mounting hole 11. The mounting post 13 is inserted into the mounting hole 11 and slides in cooperation with the mounting hole 11. The magnetic block 14 attracts the mounting post 13. This structure allows the detection head 5 to be firmly installed on the detection plate 4 and is also easy to disassemble and replace.

[0023] Reference Figure 5 Multiple rubber rings 15 are spaced apart on the sidewall of the mounting hole 11, extending along its length. Each rubber ring 15 is fitted over the mounting post 13, which presses the rubber rings against the sidewall of the mounting hole 11. The rubber rings 15 further enhance the connection stability between the detection head 5 and the detection plate 4. The rubber rings 15 are elastic; when the mounting post 13 is inserted into the mounting hole 11, the rubber rings 15 are compressed and deformed, increasing the friction between them and the post 13, thus more firmly fixing the detection head 5 to the detection plate 4. Simultaneously, the rubber rings 15 also act as a buffer and shock absorber, reducing the shaking of the detection head 5 during detection and improving detection accuracy. Compared to existing technologies, this further optimizes the mounting structure of the detection head 5 and improves the performance of the entire detection device.

[0024] Reference Figure 1 , Figure 2 and Figure 3 The lifting component includes two multi-stage hydraulic cylinders 16. In this application, the two multi-stage hydraulic cylinders 16 are respectively vertically arranged at both ends of the base 1. The ends of the telescopic rods of the multi-stage hydraulic cylinders 16 are connected to the support frame 2. The side wall of the dustproof chamber 3 is provided with an extension 17. The dustproof chamber 3 is usually rectangular. The extension 17 is arranged along the circumferential side wall of the dustproof chamber 3. The extension 17 is in close contact with the top surface of the support frame 2. The extension 17 is connected to the support frame 2 by multiple bolts, thereby realizing a stable connection between the dustproof chamber 3 and the support frame 2. There is enough space inside the dustproof chamber 3 for the detection plate 4 to slide.

[0025] Reference Figure 1 , Figure 2 and Figure 3The dustproof chamber 3 has multiple detection holes 18 for the detection head 5 to extend from. Multiple rubber sheets 19 are mounted on each detection hole 18. One end of each rubber sheet 19 is connected to the side wall of the detection hole 18, while the other end is suspended. The multiple rubber sheets 19 together form a shielding sheet 20 to block the detection holes 18. The rubber sheets 19 are made of soft and elastic rubber material, such as natural rubber or nitrile rubber. This material allows them to naturally separate when the detection head 5 extends and automatically return to their shielding state after the detection head 5 retracts, effectively preventing dust and other impurities from entering the dustproof chamber 3. In addition to the rubber sheets 19, silicone sheets can also be used, as silicone sheets have better high-temperature resistance and aging resistance.

[0026] Reference Figure 1 , Figure 2 and Figure 3 The dustproof chamber 3 is equipped with a dust removal duct 21. The dust removal duct 21 is connected to a first fan 23 via a flexible hose 22. The dust removal duct 21 is connected to a ring pipe 24 that corresponds to a plurality of detection holes 18. The ring pipe 24 is connected to a plurality of air outlet pipes 25. The plurality of air outlet pipes 25 are all oriented toward the center of the ring pipe 24. When the detection head 5 extends, it can pass through the ring pipe 24.

[0027] Reference Figure 1 , Figure 2 and Figure 3 The top of the dustproof chamber 3 is fixedly connected to a fixed frame 26. The dust removal duct 21 is rotatably mounted on the fixed frame 26 via a bearing. One end of the duct is closed, and the other end is connected to one end of the flexible hose 22 via a second pipe 28. A handwheel 27 is fitted onto the closed end. The second pipe 28 is rotatably connected to the dust removal duct 21. Specifically, a closed circular plate 29 can also be fixedly connected to the unclosed end. An insertion hole 30 is opened on the closed circular plate 29. One end of the second pipe 28 is inserted into the insertion hole 30, so that the second pipe 28 is rotatably mounted in the insertion hole 30. This structure allows the dust removal duct 21 to rotate flexibly, making it easy to adjust the air outlet direction.

[0028] Reference Figure 1 , Figure 2 and Figure 3 The first tube is L-shaped and includes a horizontal tube 31 and a vertical tube 32. One end of the horizontal tube 31 is connected to the dust removal air duct 21 and the other end is connected to the vertical tube 32. One end of the vertical tube 32 is connected to the ring tube 24. The dustproof chamber 3 is fixedly connected with a support plate 33 that corresponds to each of the multiple first tubes. One end of the horizontal tube 31 contacts the support plate 33, so that the horizontal tube 31 is parallel to the top surface of the dustproof chamber 3, and thus the vertical tube 32 is parallel to the side wall of the dustproof chamber 3 where the detection hole 18 is located.

[0029] Reference Figure 1All air outlet pipes 25 are provided with internal threads, and sealing posts 34 are threadedly connected to the air outlet pipes 25. When dust removal is not required, the sealing posts 34 can be tightened to prevent dust from entering the air outlet pipes 25.

[0030] The implementation principle of this embodiment is as follows: the dustproof chamber 3 can effectively block dust and other impurities from entering. Compared with traditional detection devices, this device can better protect the detection head 5 and improve the accuracy and reliability of the detection results.

[0031] In use, the first fan 23 delivers air to the dust removal duct 21 through the hose 22. The air is distributed to each outlet duct 25 through the first duct and the ring duct 24. The detection head 5 is moved into the ring duct 24, and the outlet duct 25 blows air toward the detection head 5, which can effectively remove dust and other impurities.

[0032] When inspecting a concrete wall, the operator can rotate the dust removal duct 21. The dust removal duct 21 rotates the first duct, which in turn rotates the ring duct 24, allowing the inspection head 5 to fit against the concrete wall for inspection, thus improving the accuracy of the inspection head 5. The rotatable dust removal duct 21 and the outlet duct 25 with sealing column 34 make the dust removal function more flexible and controllable, adapting to different inspection scenarios. This is a further improvement on existing technology, enhancing the overall performance of the inspection device.

[0033] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
