Description

Technical Field

[0001] The present invention relates to the technical field of concrete production, in particular to a device and method for detecting concrete strength and compression resistance. Background Art

[0002] Concrete is a commonly used building material, made by mixing cement, aggregates (such as sand and gravel), water, and admixtures in a certain proportion. Concrete has high compressive strength and can withstand large pressures, making it suitable for building load-bearing structures. Under appropriate environmental and maintenance conditions, it can maintain stable performance for a long time. The compressive strength testing operation of concrete during the production process is also an important aspect of measuring its quality and performance.

[0003] In the existing technology, when performing compression testing on concrete, it is difficult to conduct comprehensive supervision and analysis of the concrete sample testing process, and to make corresponding intelligent processing of the concrete samples according to the specific situation. It is also impossible to efficiently and accurately distinguish and classify the concrete samples. At the same time, the compression testing process of concrete mostly involves placing the concrete samples on the support and performing compression testing directly, without firmly clamping and positioning the concrete samples. The concrete samples are prone to movement during the testing process, resulting in inaccurate test data during the testing process, which affects the normal progress of the concrete compression testing work.

A No. 1 marking seal is provided on the output end of the first cylinder, a No. 2 marking seal is provided on the output end of the second cylinder, and a No. 3 marking seal is provided on the output end of the third cylinder.

[0039] The control panel 2 is internally provided with a processor, a data collection module, a data analysis module and an execution module;

[0040] The data collection module is used to collect the crack condition information on the concrete specimen after the concrete compression test and transmit it to the data analysis module. The crack condition information consists of the crack width factor and the crack depth factor.

[0041] It should be noted that: 5 minutes during the use of the crack detector 28 is set as the time threshold, the crack width factor represents the average width data of the cracks on the concrete sample collected by the crack detector 28 within the time threshold, and the crack depth factor represents the average depth data of the cracks on the concrete sample collected by the crack detector 28 within the time threshold. The crack detector 28 is installed on the output end of the first electric push rod 31. The larger the crack width factor and the crack depth factor, the larger the cracks generated on the concrete sample after the compression test.

[0042] The data analysis module performs concrete sample inspection, processing, control and analysis operations based on the crack condition information received on the concrete sample after the concrete compression test. The specific steps are as follows:

[0043] Obtain the crack condition information on the concrete specimen after the concrete compression test, and calibrate the crack width factor and crack depth factor as K and S respectively;

[0044] According to the formula: L = m*K + n*S, the crack detection magnitude L on the concrete specimen during the concrete compression test is obtained, where m and n are weight coefficients, both m and n are positive numbers greater than 0, and n is greater than m;

[0045] It should be noted that the pressure applied during the compression test of concrete is the maximum pressure that the produced concrete sample can theoretically withstand. The smaller the crack detection magnitude L, the smaller the cracks produced in the concrete sample after the compression test, indicating that the tested concrete has a higher compressive strength and that the tested concrete meets the quality requirements of concrete production.

[0046] If the crack detection magnitude L is equal to one, it is determined that no cracks are generated on the concrete sample after the compressive test, and a signal indicating excellent compressive performance of the concrete sample is generated. The generated signal is sent to the execution module via the processor. After receiving the signal indicating excellent compressive performance, the execution module immediately controls the first cylinder to operate. The operation of the first cylinder drives the No. 1 marking seal to move and stamp a No. 1 mark on the concrete sample. The No. 1 mark indicates that the compressive strength of the concrete sample is higher than the standard compressive strength requirement required for concrete production.

[0047] If the crack detection level L is greater than one and the crack detection level L is less than or equal to the preset crack detection level l, it is determined that a slight crack is generated on the concrete sample after the compression test, and a crack repair signal is generated. The generated signal is sent to the execution module through the processor. After receiving the repair signal, the execution module immediately controls the dual-axis motor 26 to work, and the dual-axis motor 26 drives the driving rod 44 to rotate. The driving rod 44 rotates and drives the movable ring 45 to rotate. The movable ring 45 rotates and drives the eccentric movable ring 46 to rotate. The eccentric movable ring 46 rotates and drives the installation ring 33 to move. The movement of the ring 33 drives the first movable rod 42 and the second movable rod 43 to move. The movement of the second movable rod 43 drives the fixed link 34 to move leftward, driving the closing plate 37 to move leftward, so that the discharge port remains unobstructed. The repair material is injected into the cracks on the concrete sample through the discharge head 40, and the cracks on the concrete sample are inspected and processed. After the repair is completed, the second cylinder is immediately controlled to operate. The operation of the second cylinder drives the No. 2 marking seal to move and stamp the No. 2 mark on the concrete sample. The No. 2 mark indicates that the compressive strength of the concrete sample meets the standard compressive strength requirements required for concrete production.

[0048] If the crack detection level L is greater than one and the crack detection level L is greater than a preset crack detection level l, it is determined that a large crack has occurred on the concrete sample after the compressive test, and a signal indicating poor compressive performance of the concrete sample is generated. The generated signal is sent to the execution module via the processor. After receiving the poor compressive performance signal, the execution module immediately controls the operation of the third cylinder. The operation of the third cylinder drives the No. 3 marking seal to move and stamp the No. 3 mark on the concrete sample. The No. 3 mark indicates that the compressive strength of the concrete sample is lower than the standard compressive strength requirement required for concrete production.

[0049] The data collection module in the control panel 2 is used to collect information on the crack conditions on the concrete specimens after the concrete compressive strength test, and the collected information is transmitted to the data analysis module. The concrete specimen testing process is comprehensively supervised and analyzed before and after the test, that is, the collected data is compared and analyzed with the preset stored data to obtain relevant rating signals, and the relevant components are controlled to perform corresponding processing operations accordingly. The concrete specimens can be intelligently processed according to the specific conditions during the concrete specimen testing process, and the concrete specimens can be efficiently and accurately distinguished and classified, thereby improving the efficiency of the concrete compressive strength test to ensure that the produced concrete meets the quality requirements for concrete use.

[0050] Example 2: Figure 1 、 Figure 2 、 Figure 3 and Figure 7As shown, another servo motor output end is provided with a rotating connecting rod 24 that passes through the inner wall of the moving box 19 and extends to the inside thereof, and a transmission gear 25 located inside the moving box 19 is provided at the bottom of the rotating connecting rod 24. A rotating threaded rod 47 is rotatably installed on the inner wall of the middle part of one side of the moving box 19, and a rotating gear 49 that meshes with the transmission gear 25 is sleeved on the rotating threaded rod 47. An electromagnetic strip is provided on the inner wall of the bottom end of the moving box 19, and a magnetic movable sleeve 48 that is slidably connected to the electromagnetic strip is sleeved on the rotating threaded rod 47. The end of the magnetic movable sleeve 48 close to the first positioning plate 9 is provided with a moving connecting rod 23 that passes through the inner wall of the moving box 19 and extends to the outside thereof, and the end of the moving connecting rod 23 away from the magnetic movable sleeve 48 is provided with a second positioning plate 18, and anti-slip pads are provided on the outer walls of the first positioning plate 9 and the second positioning plate 18.

[0051] The servo motor in the power chamber 12 drives the rotating connecting rod 24 to rotate, and the rotation of the rotating connecting rod 24 drives the transmission gear 25, the rotating gear 49 and the rotating threaded rod 47 to rotate. The rotation of the rotating threaded rod 47 drives the magnetic movable sleeve 48 to move, and the movement of the magnetic movable sleeve 48 drives the second positioning plate 18 to approach the first positioning plate 9. The concrete sample to be tested is placed between the first positioning plate 9 and the second positioning plate 18. The distance between the first positioning plate 9 and the second positioning plate 18 is adjusted to clamp and position the concrete sample. Through the above processing, concrete samples of different specifications can be firmly clamped and positioned, avoiding the movement of the concrete sample during the detection process, ensuring the accuracy of the detection data during the detection process, and ensuring the normal progress of the concrete compressive strength detection work.

[0052] Example 3: Figures 1-8 As shown, based on the first and second embodiments, the present invention further proposes a working method of a concrete strength and compressive strength detection device, comprising the following steps:

[0053] Step 1: The servo motor in the power chamber 12 drives the rotating connecting rod 24 to rotate, and the rotation of the rotating connecting rod 24 drives the transmission gear 25, the rotating gear 49 and the rotating threaded rod 47 to rotate. The rotation of the rotating threaded rod 47 drives the magnetic movable sleeve 48 to move, and the movement of the magnetic movable sleeve 48 drives the second positioning plate 18 to approach the first positioning plate 9. The concrete sample to be tested is placed between the first positioning plate 9 and the second positioning plate 18. The distance between the first positioning plate 9 and the second positioning plate 18 can be adjusted to firmly clamp and position concrete samples of different specifications.

[0054] Step 2: Then, the servo motor in the power chamber 12 is driven to rotate the placement column 7, and the rotation of the placement column 7 drives the rotating circular plate 6 to rotate. The rotation of the rotating circular plate 6 drives the connecting sleeve 15 to move on the movable connecting rod 16. The movement of the connecting sleeve 15 drives the rotating sleeve plate 14 and the rotating rod 21 to rotate accordingly. The rotation of the rotating rod 21 drives the rotating threaded rod 17 to rotate. The rotation of the rotating threaded rod 17 drives the moving sleeve 22 to move, and drives the placement seat 30 to move. The hydraulic testing machine 29 moves to the top of the concrete sample and starts working, applying pressure to the concrete sample to test its compressive strength.

[0055] Step 3: During the compression test of the concrete sample, the data collection module is used to collect crack condition information on the concrete sample after the compression test and transmit it to the data analysis module. The crack condition information consists of a crack width factor and a crack depth factor.

[0056] The data analysis module performs concrete sample detection, processing, control, and analysis based on the received information. The crack width factor and crack depth factor are calibrated as K and S, respectively. The crack detection magnitude L on the concrete sample during the concrete compression test is calculated using a formula.

[0057] The crack detection level L is compared with the value one and the preset crack detection level l to obtain a signal indicating that the concrete sample has excellent compressive performance, a signal indicating that the crack needs to be repaired, and a signal indicating that the concrete sample has poor compressive performance. The various signals obtained are transmitted to the execution module through the processor, and the execution module performs corresponding operation processing based on the various signals obtained.
