[0001] The utility model relates to the technical field of concrete production, in particular to a measuring device for concrete test blocks. Background Art

[0002] Concrete compressive strength is a key indicator for measuring concrete quality. It is an important parameter to ensure that buildings or structures have sufficient bearing capacity and stability during use, and to ensure their safety and durability. The accuracy of the measurement results of the concrete specimen size directly determines the accuracy and effectiveness of the compressive strength.

[0003] In the current testing standards, the measurement of concrete specimen dimensions includes the length and width of the pressure surface, flatness and verticality. The measurement method has the following main problems:

[0004] 1. The current measurement method uses a vernier caliper, a feeler gauge and a universal angle ruler for manual measurement. It takes an average of 4 minutes to measure the size of each test block, which is inefficient.

[0005] 2. The measurement results are greatly affected by human factors. Different operators may produce inconsistent measurement results due to different measurement techniques.

[0006] 3. The operator’s skill level and experience are insufficient, which may result in inaccurate readings and incorrect records during the measurement process.

[0007] Therefore, it is imperative to reduce manpower input, improve testing efficiency, and enhance the accuracy of testing data through automated transformation. Utility Model Content

[0023] First, place the concrete test block with the corresponding sample QR code on the surface onto the surface of the conveyor 7 on one side. The concrete test block can be transported from the conveyor 7 on one side to a position close to the rotating platform 5. Then, the electric slide 8 drives the connecting plate 9 to move above the concrete test block. At this time, the push cylinder 10 is started to enable the clamping cylinder 11 to move downward. The clamping cylinder 11 can clamp and fix the concrete test block, and the concrete test block is placed on the surface of the rotating platform 5 through the cooperation of the electric slide 8 and the push cylinder 10. Then, the push cylinder 10 is reset, and the 3D smart camera 6 will be able to scan the surface of the concrete test block. By scanning the QR code posted on the surface of the concrete specimen, the strength grade, molding date and other related information of the sample can be identified and recorded in the intelligent measurement. Software, and the rotating platform 5 can also drive the concrete test block to rotate ninety degrees. Through multiple rotations, the full surface scanning of the concrete test block can be achieved. After the 3D smart camera 6 has scanned the concrete test piece in all directions, the scanned 3D graphics are integrated and calculated by the software to obtain the size, flatness and adjacent surface angles of the concrete test block, so as to realize automatic detection of the size, flatness and adjacent surface angles of the concrete test block. After meeting the deviation requirements, the push cylinder 10 is matched with the clamping cylinder 11 to grab the concrete test block to the surface of the conveyor 7 on the other side, and the conveyor 7 is used to perform strength test on the press. Through the above design, the detection of the concrete test block can be completed without human intervention, which greatly improves the detection efficiency and effectively ensures the accuracy of the test data.

[0024] Furthermore, guardrails 12 are provided on both the front and rear sides of the conveyor 7, and photoelectric sensors 13 are fixed on the surface of the guardrails 12;

[0025] During the operation of the equipment, when a person approaches the size testing frame 1 and passes through the photoelectric sensors 13 on both sides, the laser rays emitted by the photoelectric sensors 13 on both sides will be blocked, so that the photoelectric sensors 13 can send out signals, so that the conveyor 7, the drive motor 4, the electric slide 8, the pushing cylinder 10 and the clamping cylinder 11 can all stop running, thereby ensuring the safety of personnel.

[0026] Furthermore, the 3D smart camera 6 is arranged in an angled structure, the surface camera of the 3D smart camera 6 is aimed at the rotating platform 5, and the 3D smart camera 6 adopts a blue structured grating binocular 3D smart camera 6 with strong anti-interference performance, and the model is Lai Gao T1Q;

[0027] Through this design, the 3D smart camera 6 can more accurately capture the concrete test block information on the surface of the rotating platform 5. The blue structured grating binocular 3D smart camera 6 has a 280x210x210mm3 measuring format, a 1.31 million pixel industrial camera, and a single-frame projection time of 0.1 seconds. It has a large single-frame scanning range and high detection accuracy, which can improve the accuracy of the detection results.

[0028] Furthermore, there are two electric slides 8, which are located at the front and rear sides of the top of the size testing frame 1;

[0029] By setting the number of the electric slides 8 to two, the front and rear sides of the connecting plate 9 can be more evenly stressed, thus avoiding deflection that is easily caused by unilateral stress.

[0030] Furthermore, the driving motor 4 is a servo motor, and a brake device is installed at the tail of the driving motor 4;

[0031] The servo motor can accurately control the rotation angle of its own output shaft, thereby achieving accurate control of the rotation angle of the rotating platform 5, and the brake device can make the output shaft of the driving motor 4 achieve a self-locking effect when the driving motor 4 stops rotating, thereby preventing the rotating platform 5 from rotating on its own during the detection process.

[0032] Further, a controller 14 is fixed on the surface of the extension frame 3, and the controller 14 is electrically connected to the conveyor 7, the pushing cylinder 10, the electric slide 8, the clamping cylinder 11, the driving motor 4, the 3D smart camera 6 and the photoelectric sensor 13;

[0033] Enables the controller 14 to receive signals and operate multiple devices.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
