Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, unless otherwise specified, "plurality" means two or more.

[0043] As demonstrated in the background art, in related technologies, a worker uses a handheld penetrometer to dynamically insert a probe into a hardened concrete specimen, measuring the penetration depth. Based on a predetermined correlation between penetration depth and concrete strength, the concrete's compressive strength is then estimated. After the penetrometer completes the strength test on a specimen, the penetrometer must be manually lifted to replace the specimen and proceed to the next strength test. However, this handheld penetrometer method is time-consuming and labor-intensive, resulting in low testing efficiency.

[0044] Based on this, the concrete strength testing device provided in the embodiment of the present application is provided with a base, a sliding assembly, a mounting bracket, and a detection assembly. The base has a detection platform, and the detection platform is used to place the concrete sample. The mounting bracket includes a bracket body, a first mounting portion and at least one second mounting portion provided on the bracket body. The first mounting portion and the second mounting portion are both connected to the detection assembly, thereby improving the stability of the detection assembly. The sliding assembly is provided on the base, and the bracket body is slidably connected to the sliding assembly. The sliding assembly can drive the mounting bracket and the detection assembly to slide relative to the concrete sample on the detection platform, facilitating the detection assembly to detect the strength of the concrete sample and improving detection efficiency.

[0045] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0046] Reference Figure 1 and Figure 2 As shown, the concrete strength detection device provided in the embodiment of the present application includes a base 100, a sliding assembly 200, a mounting bracket 400 and a detection assembly 300. The base 100 has a detection platform 110, and the detection platform 110 is used to place a concrete sample 10.

[0047] The sliding assembly 200 is disposed on the base 100 .

[0048] The mounting bracket 400 includes a bracket body 410 and a first mounting portion 420 and at least one second mounting portion 430 provided on the bracket body 410 . The bracket body 410 is slidably connected to the sliding assembly 200 , and the first mounting portion 420 and the second mounting portion 430 are both connected to the detection assembly 300 .

[0049] The sliding assembly 200 drives the mounting bracket 400 and the detection assembly 300 to approach the concrete sample 10 , so that the detection assembly 300 detects the strength of the concrete sample 10 .

[0050] A testing platform 110 is provided on the base 100 . The testing platform 110 provides a stable placement surface for the concrete sample 10 to ensure that the concrete sample 10 remains stable during the test, which is beneficial to ensuring the accuracy and reliability of the test results.

[0051] By setting a first mounting portion 420 and a second mounting portion 430 on the bracket body 410, both the first mounting portion 420 and the second mounting portion 430 are connected to the detection component 300, which helps to improve the stability of the detection component 300 and ensures that the angle of the detection component 300 remains unchanged during the detection process, thereby improving the accuracy of the detection results.

[0052] The first mounting portion 420 and the second mounting portion 430 are both connected to the detection component 300 to make the connection between the detection component 300 and the bracket body 410 more secure, reduce the possibility of the detection component 300 falling off, and improve the reliability and safety of the device.

[0053] The sliding assembly 200 is arranged on the base 100, and the base 100 provides support for the sliding assembly 200. The bracket body 410 is slidably connected to the sliding assembly 200. The first mounting portion 420 and the second mounting portion 430 are both connected to the detection assembly 300, so that the detection assembly 300 is connected to the sliding assembly 200 through the mounting bracket 400. The sliding assembly 200 can drive the mounting bracket 400 and the detection assembly 300 to slide relative to the concrete sample 10 on the detection platform 110.

[0054] Specifically, when testing multiple concrete specimens 10, the first concrete specimen 10 is placed on the testing platform 110, and the sliding assembly 200 drives the mounting bracket 400 and the testing assembly 300 to approach the first concrete specimen 10 until the testing assembly 300 is directly above the first concrete specimen 10 (i.e. Figure 1 The detection assembly 300 dynamically penetrates into the first concrete sample 10 to detect the strength of the first concrete sample 10 .

[0055] After the assembly 300 to be tested completes the strength test on the first concrete specimen 10, the sliding assembly 200 drives the mounting bracket 400 and the testing assembly 300 away from the first concrete specimen 10 and removes the first concrete specimen 10 from the testing platform 110. A second concrete specimen 10 is then placed on the testing platform 110, and the sliding assembly 200 drives the mounting bracket 400 and the testing assembly 300 closer to the second concrete specimen 10, allowing the testing assembly 300 to test the strength of the second concrete specimen 10. Repeating these steps allows for the testing of multiple concrete specimens 10. Therefore, this concrete strength testing device facilitates the testing of the strength of concrete specimens 10 and improves testing efficiency.

[0056] In some embodiments, reference Figure 2 As shown, the concrete strength detection device also includes a first mounting member 440 and two second mounting members 450. The first mounting member 440 connects the upper part of the detection component 300 to the first mounting portion 420, and the second mounting member 450 connects the lower part of the detection component 300 to the second mounting portion 430.

[0057] In a specific implementation, the upper part of the detection component 300 can be first pressed against the first mounting portion 420, and the lower part of the detection component 300 can be pressed against the second mounting portion 430, and then the first mounting member 440 can be connected to the first mounting portion 420, so that the upper part of the detection component 300 is restricted to the area enclosed by the first mounting member 440 and the first mounting portion 420, and the first mounting member 440 and the first mounting portion 420 jointly fix the upper part of the detection component 300.

[0058] The second mounting member 450 is then connected to the second mounting portion 430, thereby confining the lower portion of the detection assembly 300 within the area enclosed by the second mounting member 450 and the second mounting portion 430. The second mounting member 450 and the second mounting portion 430 jointly secure the lower portion of the detection assembly 300. Thus, by providing the first mounting member 440 and the second mounting member 450, both the first mounting portion 420 and the second mounting portion 430 are connected to the detection assembly 300.

[0059] In some embodiments, reference Figure 2 As shown, the concrete strength detection device further includes two first connecting members 460 and at least two second connecting members 470 . The first connecting member 460 connects the first mounting member 440 and the first mounting portion 420 , and the second connecting member 470 connects the second mounting member 450 and the second mounting portion 430 .

[0060] It is understandable that by providing two first connecting members 460, the two first mounting members 440 can be securely connected to the first mounting portion 420. For example, the first connecting member 460 can be a screw and a nut that matches the screw. Through holes can be provided at both ends of the first mounting portion 420 and the first mounting member 440. The screws pass through the through holes on the first mounting portion 420 and the first mounting member 440 in sequence and then are threadedly connected to the nut. The first connecting member 460 can also be other components, and this embodiment of the application does not impose too many restrictions on this.

[0061] At least two second connecting members 470 are provided. The two second connecting members 470 may be two, and the two second connecting members 470 respectively connect the second mounting member 450 and the second mounting portion 430 at both ends. There may also be more than two second connecting members 470, and this embodiment of the present application does not impose any additional restrictions on this. For example, the second connecting member 470 may be a screw and a nut that matches the screw. Through holes may be provided on both the second mounting portion 430 and the second mounting member 450, and the screws may sequentially pass through the through holes on the second mounting portion 430 and the second mounting member 450, and then be threadedly connected to the nuts. The second connecting member 470 may also be other components, and this embodiment of the present application does not impose any additional restrictions on this.

[0062] In some embodiments, reference Figure 2 As shown, a bending section 431 is provided on the second mounting portion 430 , and the second connecting member 470 is connected to the second mounting member 450 via the bending section 431 .

[0063] Specifically, the second mounting portion 430 is provided with a bent section 431, and the second connecting member 470 abuts against the bent section 431, which can limit the position of the second connecting member 470 so that the second connecting member 470 connects the second mounting portion 430 and the second mounting member 450. Furthermore, the second connecting member 470 is connected to the second mounting member 450 via the bent section 431, making the installation and removal of the second connecting member 470 more convenient, thereby improving detection efficiency.

[0064] It should be noted that the bending section 431 can be bent toward the detection component 300 or away from the detection component 300, and the embodiment of the present application does not impose too many restrictions on this.

[0065] In some embodiments, reference Figure 1 and Figure 2 As shown, the sliding assembly 200 includes a first sliding member 210 and a second sliding member 220 .

[0066] The first sliding member 210 is slidably disposed on the second sliding member 220 , and the first sliding member 210 can slide along an extending direction of the second sliding member 220 .

[0067] The bracket body 410 is slidably connected to the first sliding member 210 , and the bracket body 410 and the detection assembly 300 can slide along the extension direction of the first sliding member 210 .

[0068] Specifically, the second sliding member 220 moves along Figure 1 The first sliding member 210 is slidably arranged on the second sliding member 220 as shown by the middle arrow in the Y direction. The first sliding member 210 can slide along the extension direction of the second sliding member 220, that is, the first sliding member 210 can slide along the positive direction of Y or the negative direction of Y.

[0069] The first sliding member 210 moves along Figure 1 The Z direction is shown by the middle arrow, and the bracket body 410 is slidably connected to the first sliding member 210. The bracket body 410 and the detection component 300 can slide along the extension direction of the first sliding member 210, that is, the bracket body 410 can drive the detection component 300 to slide along the positive direction of Z or the negative direction of Z.

[0070] In some embodiments, reference Figure 1 and Figure 2 As shown, the sliding assembly 200 further includes at least one third sliding member 230 , and the third sliding member 230 is connected to the base 100 .

[0071] The second sliding member 220 is slidably disposed on the third sliding member 230 , and the second sliding member 220 can slide along an extending direction of the third sliding member 230 .

[0072] At least one third sliding member 230. For example, there can be one or two third sliding members 230. The two third sliding members 230 can be arranged parallel to each other. The embodiment of the present application does not impose too many restrictions on the number of third sliding members 230.

[0073] Reference Figure 1 As shown, the third sliding member 230 is connected to the base 100, and the base 100 provides support for the third sliding member 230. The third sliding member 230 is connected to the base 100. Figure 1 The second sliding member 220 is slidably arranged on the third sliding member 230 as shown by the arrow in the X direction. The second sliding member 220 can slide along the extension direction of the third sliding member 230, that is, the second sliding member 220 can slide along the positive direction of X or the negative direction of X.

[0074] Therefore, by setting the first sliding member 210, the second sliding member 220 and the third sliding member 230, the bracket body 410 and the detection component 300 can be driven to move along the X, Y or Z direction (XYZ are perpendicular to each other) to make the detection component 300 approach or move away from the concrete sample 10, so that the detection component 300 can detect the strength of the concrete sample 10.

[0075] In some embodiments, reference Figure 1 and Figure 2 As shown, one of the first sliding member 210 , the second sliding member 220 and the third sliding member 230 includes a sliding rail 231 and a mounting seat 232 slidably connected to the sliding rail 231 .

[0076] For example, the third sliding member 230 may include a slide rail 231 and a mounting seat 232. The mounting seat 232 is slidably connected to the slide rail 231. The second sliding member 220 is connected to the mounting seat 232. The mounting seat 232 can drive the second sliding member 220 to move relative to the slide rail 231 along the slide rail. Figure 1 The arrow in the middle indicates the positive direction of X or the negative direction of X.

[0077] For example, the second sliding member 220 may include a slide rail 231 and a mounting seat 232. The mounting seat 232 is slidably connected to the slide rail 231. The first sliding member 210 is connected to the mounting seat 232. The mounting seat 232 can drive the first sliding member 210 to move relative to the slide rail 231 along the slide rail. Figure 1 The arrow in the middle indicates movement in the positive direction of Y or the negative direction of Y.

[0078] For example, the first sliding member 210 may include a slide rail 231 and a mounting seat 232, the mounting seat 232 is slidably connected to the slide rail 231, the bracket body 410 is connected to the mounting seat 232, and the mounting seat 232 can drive the bracket body 410 to move relative to the slide rail 231 along the Figure 1 The arrow in the middle indicates movement in the positive direction of Z or the negative direction of Z.

[0079] It should be noted that, in a specific implementation, the mounting seat 232 can be driven to slide manually, or a driving member can be provided, which is connected to the mounting seat 232 to drive the mounting seat 232 to slide relative to the slide rail 231. The embodiment of the present application does not impose too many restrictions on this.

[0080] In some embodiments, reference Figure 1 As shown, the detection assembly 300 includes a probe 310, a displacement detection member and a resistance detection member.

[0081] The stylus 310 is used to penetrate into the concrete sample 10 , the displacement detection member is used to measure the penetration depth of the stylus 310 , and the resistance detection member is used to detect the penetration resistance of the stylus 310 .

[0082] It should be noted that concrete strength testing is typically performed through static penetration, where penetration resistance and depth are measured to determine penetration. A mathematical model is established using the penetration resistance and depth calculated from the penetration resistance and depth, along with concrete strength, to identify concrete mechanical parameters and strength. This data is then linked to concrete strength to obtain these parameters, making it highly efficient and convenient.

[0083] Specifically, the penetration test of the concrete sample 10 is performed by setting the measuring needle 310 , the displacement detection component detects the penetration depth of the measuring needle 310 , and the resistance detection component detects the penetration resistance of the measuring needle 310 .

[0084] In some embodiments, reference Figure 1 As shown, the concrete strength detection device further includes a controller 500 , which is connected to the base 100 , and the sliding assembly 200 and the detection assembly 300 are both electrically connected to the controller 500 .

[0085] The controller 500 controls the sliding assembly 200 to drive the mounting bracket 400 and the detection assembly 300 to approach the concrete sample 10, so that the displacement detection part detects the penetration depth and the resistance detection part detects the penetration resistance; when one of the penetration depth and the penetration resistance is greater than or equal to a preset value, the controller 500 controls the sliding assembly 200 to drive the mounting bracket 400 and the detection assembly 300 away from the concrete sample 10.

[0086] The controller 500 is connected to the base 100. For example, the controller 500 and the base 100 can be fixedly connected or detachably connected, and the embodiment of the present application does not impose too many restrictions on this.

[0087] The sliding assembly 200 is electrically connected to the controller 500, and the controller 500 can control the sliding assembly 200 to drive the mounting bracket 400 and the detection assembly 300 to move relative to the concrete sample 10; the detection assembly 300 is electrically connected to the controller 500, and the controller 500 can control the detection assembly 300 to perform a penetration test on the concrete sample 10 and detect the penetration depth and penetration resistance.

[0088] It should be noted that the controller 500 can also be used to set the penetration plan, including the location of the measuring points, the number of measuring points and the coordinates. Figure 1 and Figure 3 As shown, the concrete sample 10 is placed on the detection platform 110. By inputting the size of the concrete sample 10, the controller 500 can generate nine measuring points, namely the first measuring point 11, the second measuring point 12, the third measuring point 13, the fourth measuring point 14, the fifth measuring point 15, the sixth measuring point 16, the seventh measuring point 17, the eighth measuring point 18 and the ninth measuring point 19, and control the sliding component 200 to drive the detection component 300 to detect the nine measuring points in sequence.

[0089] It should also be noted that concrete strength testing methods generally include the fixed-depth force penetration method and the fixed-force depth penetration method. In practice, the penetration depth and penetration resistance parameters of the stylus 310 can be recorded, and two trigger conditions for the end of the test can be set. For example, the penetration depth can be preset to 10 mm (i.e., a first preset value), and the penetration resistance can be preset to 350 N (i.e., a second preset value).

[0090] When the displacement detector detects that the penetration depth of the stylus 310 at the first measuring point 11 has reached a first preset value, or when the resistance detector detects that the penetration resistance of the stylus 310 at the first measuring point 11 has reached a second preset value, the controller 500 controls the stylus 310 to stop advancing and withdraw. The controller 500 then controls the sliding assembly 200 to drive the mounting bracket 400 and the detection assembly 300 to continue advancing to the second measuring point 12. This process repeats until the ninth measuring point 19 is detected.

[0091] Controller 500 calculates the concrete strength at the corresponding test point based on the ratio of the penetration resistance to the penetration depth when stylus 310 stops advancing. After completing the strength test data for nine test points, it outputs the comprehensive strength of concrete sample 10. For example, the strength of concrete sample 10 is 0.3-10 MPa.

[0092] In some embodiments, reference Figure 1 As shown, the base 100 includes a support frame 120 , a plurality of support columns 130 and a plurality of fixing members 140 . Each fixing member 140 connects a support column 130 and the support frame 120 , and the sliding assembly 200 is disposed on the support column 130 .

[0093] As will be appreciated, each fixing member 140 connects the corresponding support column 130 to the support frame 120, ensuring a secure connection between the support column 130 and the support frame 120, thereby improving the stability of the base 100 and enabling the base 100 to withstand greater weight and external forces. Furthermore, the distribution of multiple support columns 130 at different locations on the support frame 120 allows the base 100 to be subjected to a more uniform load, reducing pressure on a single support point and extending the service life of the base 100. By way of example, the fixing member 140 may be a fixed angle bracket assembly or other component, and this embodiment of the present application does not impose any further limitations on this aspect.
