Description

Technical Field

[0001] This application relates to the field of concrete detection technology, specifically to a non-destructive testing device for concrete structures that combines precise positioning and vibration reduction functions. Background Technology

[0002] Concrete is characterized by its abundant and inexpensive raw materials and simple production process, leading to its ever-increasing usage. It also boasts high compressive strength, good durability, and a wide range of strength grades. These characteristics make it widely applicable, not only in various civil engineering projects but also in shipbuilding, machinery manufacturing, marine development, geothermal engineering, and other fields, where concrete plays a crucial role.

[0003] In practical applications, the quality of concrete is evaluated by detecting defects inside the concrete. However, when measuring concrete with a single probe, the measurement error is relatively large, and multiple measurements cannot be performed simultaneously.

[0004] To address the aforementioned issues, patent document CN208833711U discloses a non-destructive testing device for concrete structures that combines precise positioning and vibration reduction functions. This device utilizes multiple probes, with probe heads at the bottom of each probe, allowing for simultaneous multiple measurements and saving time. However, this testing device has the following drawbacks in practical use:

[0005] 1. When inspecting concrete surfaces, the equipment cannot move flexibly in all directions, resulting in low inspection efficiency. For example, when inspecting irregularly shaped concrete areas or areas with obstacles, the equipment has difficulty changing direction easily, requiring operators to spend time adjusting the position, which greatly reduces inspection efficiency.

[0006] 2. Precise positioning and detection cannot be achieved when conducting concrete testing.

[0007] 3. When the probe is pressed, it may be pressed too hard, causing damage to the probe and the base plate of the equipment. Utility Model Content

[0008] Therefore, this application provides a non-destructive testing device for concrete structures that combines precise positioning and vibration reduction functions, in order to solve the problems of low detection efficiency and poor detection accuracy of existing detection devices.

[0009] To achieve the above objectives, this application provides the following technical solution:

[0010] A non-destructive testing device for concrete structures with both precise positioning and vibration reduction functions includes a housing, which includes a top plate, a bottom plate and side plates. Multiple probes are evenly arranged between the top plate and the bottom plate, and the bottom of each probe passes through the bottom plate and is equipped with a probe head for detecting internal defects in the concrete. Each probe is also equipped with a connector for connecting to an ultrasonic phased array testing device.

[0011] Shock absorbers are respectively installed at the four corners between the top plate and the bottom plate. The bottom of the shock absorber extends out of the bottom plate and is equipped with a omnidirectional ball. Multiple infrared positioning modules are also arranged at intervals at the bottom of the bottom plate.

[0012] Optionally, the bottom of the base plate is also provided with a plurality of cushioning pads evenly distributed.

[0013] Optionally, the shock absorber includes a shock-absorbing housing, the shock-absorbing housing is provided with a first rotating nut located at the upper part and a connecting rod located at the lower part, a first spring is provided between the first rotating nut and the connecting rod, and the universal ball is provided at the bottom end of the connecting rod.

[0014] Optionally, the probe rod includes a probe housing, the probe housing is provided with a second rotating nut and a probe post, the second rotating nut and the probe post are connected by a second spring, and the probe head is fixedly connected to the bottom end of the probe post.

[0015] Optionally, the side wall of the detection housing is provided with a groove, and the connecting plug is provided on one side of the detection column corresponding to the groove, and the connecting plug can slide in the groove.

[0016] Optionally, it also includes hand levers, two of which are symmetrically arranged on both sides of the top plate along the length direction;

[0017] Alternatively, the two handles may be respectively disposed on the outer sides of the two side plates.

[0018] Optionally, the handle is made of a non-slip material.

[0019] Optionally, multiple probes are arranged in an array.

[0020] Compared with the prior art, this application has at least the following beneficial effects:

[0021] 1. Based on further analysis and research of existing technical problems, this application provides a non-destructive testing device for concrete structures that combines precise positioning and vibration damping functions. It includes multiple probes mounted on a shell, four vibration dampers positioned at the four corners between the top and bottom plates of the shell, with the bottom ends of the dampers extending out of the bottom plate and equipped with omnidirectional balls. Multiple infrared positioning modules are also spaced apart at the bottom of the bottom plate. This application features a simple structure and ease of use. Multiple probes enable multi-point detection, and the omnidirectional balls allow the device to flexibly change direction and position during testing, significantly shortening testing time, improving efficiency, and minimizing errors. The infrared positioning modules accurately determine the relative position of the probe head and the target detection point, improving the accuracy of the test results. Furthermore, the automatic position adjustment and synchronous extension / retraction mechanism of the probe head and omnidirectional balls enhance the device's applicability in complex environments.

[0022] 2. The bottom of the base plate of this application is evenly provided with multiple buffer pads.

[0043] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "including," "comprising," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0045] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to indicate the general relative positional relationship for the purpose of intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product.

[0046] like Figures 1-12 As shown, a non-destructive testing device for concrete structures with both precise positioning and vibration reduction functions includes a housing 1. The housing 1 includes a top plate 11, a bottom plate 12, and side plates 13. A plurality of probe rods 2 are evenly arranged between the top plate 11 and the bottom plate 12, and the bottom of the probe rod 2 passes through the bottom plate 12 and is provided with a probe head 5 for detecting internal defects in the concrete. The probe rod 2 is provided with a connector plug 8 for connecting to an ultrasonic phased array testing device. Two side plates 13 are arranged on both sides along the length direction of the top plate 11 and the bottom plate 12, and the two ends of the side plates are respectively connected to the top plate 11 and the bottom plate 12 by screws.

[0047] Shock absorbers 3 are respectively installed at the four corners between the top plate 11 and the bottom plate 12. The bottom of the shock absorber 3 extends out of the bottom plate 12, and a universal ball 4 is installed at the bottom of the shock absorber 3. Multiple infrared positioning modules 7 are also arranged at intervals at the bottom of the bottom plate 12.

[0048] When the probe head 5 is pressed against the concrete surface for testing, the shock absorber 3 can assist the universal ball 4 and the probe head 5 in synchronous extension and retraction during the pressing operation, without affecting the normal testing operation of the probe head 5. The universal ball 4 can increase the omnidirectional flexible movement of the equipment on the concrete testing surface, and can support the overall weight of the equipment when it is not in operation, protecting the probe head 5 from damage. At the same time, the infrared positioning module 7 can assist the equipment in precise positioning and testing. The specific number and setting position of the infrared positioning module 7 can be set according to the requirements, including two modes: cross mode and rectangular frame mode. Different modes can be selected for auxiliary testing according to the testing requirements.

[0049] Preferably, the bottom of the base plate 12 is also evenly provided with multiple buffer pads 6, which can be rubber pads, silicone pads, or other materials. When the probe head 5 is pressed, the buffer pads 6 can prevent the probe head 5 from being pressed excessively, thus preventing damage to the probe head 5 and the equipment base plate 12; at the same time, they can increase the friction between the equipment and the concrete detection surface, preventing the equipment from sliding laterally, thereby further improving the accuracy of the detection results.

[0050] More preferably, such as Figures 7-9 As shown, the shock absorber 3 includes a shock absorber housing 31. The shock absorber housing 31 is provided with a first rotating nut 32 located at the upper part and a connecting rod 33 located at the lower part. A first spring 34 is provided between the first rotating nut 32 and the connecting rod 33. A universal ball 4 is provided at the bottom end of the connecting rod 33.

[0051] When the equipment is in operation, the concrete surface may be uneven. When the operator applies force downward, multiple probes 5 and four universal balls 4 are subjected to reaction forces. Due to the action of the first spring 34 and the second spring 24, the probes 5 and universal balls 4 at each position can move independently. The movement distance may be different, but they can maintain synchronous extension and contraction to adapt to the uneven surface of the concrete, ensure the normal detection work of the probes 5, reduce measurement errors, and improve the accuracy and reliability of the detection.

[0052] like Figure 6 As shown, the above-mentioned probe rod 2 includes a probe housing 21, the probe housing 21 is provided with a second rotating nut 22 and a probe post 23, the second rotating nut 22 and the probe post 23 are connected by a second spring 24, and the probe head 5 is fixedly connected to the bottom end of the probe post 23.

[0053] The side wall of the detection housing 21 is provided with a groove 211, and a connecting plug 8 is provided on the side of the detection column 23 corresponding to the groove 211, and the connecting plug 8 can slide in the groove 211.

[0054] The second rotating nut 22 is installed on the top of the detection housing 21 by a threaded connection. The distance between the rotating nut 22 and the detection post 23 can be adjusted up or down, thereby adjusting the deformation of the second spring 24 and adjusting the elastic force of the second spring 24.

[0055] The first rotating nut 32 is also installed on the top of the shock-absorbing housing 31 by a threaded connection. The distance between the rotating nut and the probe post 23 is adjusted by the second rotating nut 22, thereby changing the elastic force of the second spring 24.

[0056] Preferably, it also includes a lever 9 mounted on the housing 1, which can help the operator apply force more conveniently and ensure that the force is applied evenly.

[0057] Two levers 9 are symmetrically arranged on both sides of the top plate 11 along its length, see [reference]. Figure 1 and Figure 2 Alternatively, the two levers 9 can be respectively installed on the outer sides of the two side plates 13, see [reference]. Figure 10 and Figure 11 The two levers are positioned symmetrically, allowing operators to place both hands simultaneously, ensuring even force application and reducing equipment tilting or instability caused by applying force with one hand.

[0058] In addition, the surface of the handle 9 can also be made of anti-slip material to increase the friction between the hand and the handle 9, prevent hand slippage, and improve the safety and stability of operation; the shape of the handle 9 can be designed to fit the hand grip to improve the comfort and stability of operation.

[0059] The aforementioned multiple probe rods 2 are arranged in an array, which can be flexibly adjusted according to detection requirements and equipment design during actual use. The following are the specific arrangements of the probe rods 2 in two embodiments:

[0060] In one embodiment, see Figure 12 Multiple probes 2 are evenly arranged in two rows, totaling 16 probes. The number of probes 2 in each row is the same, and the spacing between the probes 2 in each row is the same, ensuring the uniformity and comprehensiveness of the detection. This arrangement is suitable for situations where detection is required in a relatively small area.

[0061] In another embodiment, see Figure 3 Multiple probe rods 2 are evenly arranged in four rows, totaling 32, with each row containing the same number of probe rods 2. This arrangement is suitable for situations where detection is carried out over a large area.

[0062] Preferably, a fixing rod is also provided between the top plate 11 and the bottom plate 12; bolt holes are provided on both sides of the bottom plate 12 for installing bolts. The bolts pass through the bolt holes to adjust their length. When the operator presses down with both hands to a certain extent, the presence of the bolts will hold the concrete surface, preventing the operator from pressing down further and thus preventing excessive pressure from damaging the detector head 5. This method can limit the pressure applied by the operator to a certain extent, preventing damage to the detector head 5 due to excessive pressure.

[0063] In summary, this application has at least the following advantages:

[0064] 1. Multiple probes are set up to achieve multi-point detection, which greatly shortens the detection time, improves the detection efficiency, and reduces the error. Moreover, the omnidirectional movement function of the ball allows the equipment to flexibly change direction and position during the detection process, reducing the time wasted due to equipment adjustment and further improving the detection efficiency.

[0065] 2. Multi-point detection can more accurately reflect the true condition of the internal structure of concrete. The probe and omnidirectional ball can automatically adjust their position according to the specific conditions of the concrete surface to adapt to uneven surfaces, ensuring that the probe always maintains good contact with the detection surface, making the detection signal more stable and reliable, and improving detection accuracy; the infrared positioning module assists the device in precise positioning detection, which can accurately determine the relative position of the probe and the target detection point, avoiding detection errors caused by position deviations and ensuring the accuracy of the detection results.

[0066] 3. The automatic position adjustment and synchronous extension mechanism of the probe and omnidirectional ball enable the equipment to adapt well to complex and irregular concrete surfaces, thereby accurately covering the area to be inspected and improving the applicability of the equipment in complex environments.

[0067] 4. Multiple buffer pads are evenly distributed on the bottom of the base plate. When the probe is pressed, the buffer pads can prevent the probe from being pressed too hard and damaging the probe and the base plate of the equipment. At the same time, they increase the friction between the equipment and the concrete testing surface, preventing the equipment from sliding sideways, thereby further improving the accuracy of the test results.

[0068] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
