[0002] One of the main indicators of concrete quality is the compressive strength. Therefore, before the concrete is put into use, it is necessary to detect the strength of concrete test blocks through a strength detection device. The common detection method is to apply pressure to the concrete test blocks until the test blocks are broken to detect the compressive strength of the test blocks.
[0003] When using a detection device to detect concrete samples, the concrete generally needs to be crushed under pressure to obtain accurate detection data. However, the crushed concrete is not convenient to clean and collect; due to the different thicknesses and strengths of concrete, it is necessary to detect the thickness of the concrete before detecting its strength. Generally, it is not easy for a general strength detection device to detect the thickness, which easily leads to a relatively single function when using the strength detection device; when the concrete test blocks are placed for detection, they are generally positioned by the plates on both sides, and the positioning is relatively slow, which affects the working efficiency of the strength detection device when positioning the concrete test blocks.

[0015] 1. By providing a debris shielding and collecting mechanism, before detection, the retaining frame can be fixed on the surface of the base by screws, so that the retaining frame is located outside the concrete test block. Since the retaining frame is made of a transparent material, it does not affect the staff's observation of the concrete test block.

Guide rods 15 are arranged on both sides of the surface of the support frame 14. One end of the guide rod 15 penetrates through the support frame 14 and is fixedly connected to the surface of the pressing plate 13.
[0025] Furthermore, as Figure 2As shown in the figure, a debris shielding and collecting mechanism 2 is provided on the surface of the base 1. The debris shielding and collecting mechanism 2 is composed of a collecting box 21, a retaining frame 22, a receiving cavity 23 and collecting holes 24. A retaining frame 22 is provided on the surface of the base 1. The retaining frame 22 is made of a transparent material and is detachably connected to the base 1 by screws. A receiving cavity 23 is formed on the surface of the base 1. A collecting box 21 is arranged inside the receiving cavity 23. The collecting box 21 is slidably matched with the receiving cavity 23. Collecting holes 24 are formed on the surface of the base 1. The collecting holes 24 communicate with the receiving cavity 23 and are located inside the retaining frame 22.
[0026] During use, before detection, the retaining frame 22 can be fixed on the surface of the base 1 by screws, so that the retaining frame 22 is located outside the concrete test block. Since the retaining frame 22 is made of a transparent material, it does not affect the staff's observation of the concrete test block. When the concrete test block is crushed during detection, the retaining frame 22 can prevent debris from splashing. At the same time, under the action of the collecting holes 24, it is convenient for smaller debris to pass through the collecting holes 24 and enter the inside of the collecting box 21, facilitating the cleaning and collection of the debris, so as to realize the function that the strength detection device is convenient for collecting and cleaning the debris of the concrete test block.
[0027] Furthermore, as Figure 4 shown in the figure, a thickness detection mechanism 3 is provided on the surface of the base 1. The thickness detection mechanism 3 includes a scale rod 31 and a thickness detection component 32 inside. A scale rod 31 is rotatably connected to the surface of the base 1.

A detection strip 321 is fixed on one side of the sliding ring 322.
[0028] During use, pull up the detection strip 321 to drive the sliding ring 322 to slide along the scale rod 31. Then rotate the scale rod 31 to drive the detection strip 321 to rotate, so that the detection strip 321 is located above the concrete test block. Then press down the detection strip 321 to make the detection strip 321 contact the surface of the concrete test block, and the corresponding value on the surface of the scale rod 31 can be read through the reading scale 323 to detect the thickness of the concrete test block. After the detection is completed, the scale rod 31 can be rotated to make the detection strip 321 parallel to the concrete test block, which does not affect the strength detection of the concrete test block, so as to realize the thickness detection function of the strength detection device for the concrete test block.
[0029] Furthermore, as Figure 3As shown in the figure, a positioning mechanism 4 is provided on the surface of the base 1. The positioning mechanism 4 is composed of a sleeve frame 41, a positioning plate 42, a fastening bolt 43 and an adjusting block 44. A positioning plate 42 is provided on the surface of the base 1. The positioning plate 42 is located on one side inside the retaining frame 22. The structure of the positioning plate 42 is an L-shaped structure. A sleeve frame 41 is fixed on the surface of the base 1. The sleeve frame 41 is inclined at 45 degrees. An adjusting block 44 is slidably arranged inside the sleeve frame 41. One end of the adjusting block 44 is fixedly connected to the surface of the positioning plate 42. The surface of the sleeve frame 41 is threadedly connected with a fastening bolt 43. One end of the fastening bolt 43 penetrates through the sleeve frame 41 and presses and fastens the surface of the adjusting block 44.
[0030] During use, loosen the fastening bolt 43, and then pull the positioning plate 42, so that the positioning plate 42 drives the adjusting block 44 to slide along the sleeve frame 41. Since the sleeve frame 41 is inclined at 45 degrees, the positioning plate 42 moves along the direction of the sleeve frame 41, which is convenient for the positioning plate 42 to position concrete test blocks of different sizes. Since the positioning plate 42 is an L-shaped structure, the two sides of the concrete test block can be quickly positioned. During use, only need to place the concrete test block on the surface of the base 1 so that its two sides are respectively in close contact with the two sides of the positioning plate 42, so as to realize the quick positioning function of the strength detection device for the concrete test block.
[0031] Working principle: During use, first loosen the fastening bolt 43, and then pull the positioning plate 42, so that the positioning plate 42 drives the adjusting block 44 to slide along the sleeve frame 41. Since the sleeve frame 41 is inclined at 45 degrees, the positioning plate 42 moves along the direction of the sleeve frame 41, which is convenient for the positioning plate 42 to position concrete test blocks of different sizes. Since the positioning plate 42 is an L-shaped structure, the two sides of the concrete test block can be quickly positioned. During use, only need to place the concrete test block on the surface of the base 1 so that its two sides are respectively in close contact with the two sides of the positioning plate 42, so as to realize the quick positioning function of the strength detection device for the concrete test block, thereby improving the working efficiency of the strength detection device when positioning the concrete test block.
[0032] Subsequently, the detection strip 321 can be pulled upward, so that the detection strip 321 drives the sliding ring 322 to slide along the scale rod 31. Then rotate the scale rod 31, so that the scale rod 31 drives the detection strip 321 to rotate, so that the detection strip 321 is located above the concrete test block. Then press down the detection strip 321 so that the detection strip 321 contacts the surface of the concrete test block, and the corresponding value on the surface of the scale rod 31 can be read through the reading scale 323 to detect the thickness of the concrete test block. After the detection is completed, the scale rod 31 can be rotated so that the detection strip 321 is parallel to the concrete test block, which does not affect the strength detection of the concrete test block, so as to realize the thickness detection function of the strength detection device for the concrete test block, and the functionality is stronger.
[0033] Before the detection, the retaining frame 22 can be fixed on the surface of the base 1 through screws, so that the retaining frame 22 is located outside the concrete test block. Since the retaining frame 22 is made of transparent material, it does not affect the staff's observation of the concrete test block. When the concrete test block is crushed during the detection, the retaining frame 22 can prevent the fragments from splashing. At the same time, under the action of the collection hole 24, it is convenient for smaller fragments to pass through the collection hole 24 and enter the interior of the collection box 21, facilitating the cleaning and collection of the fragments, so as to realize the function that the strength detection device is convenient for collecting and cleaning the fragments of the concrete test block, thereby improving the convenience of the strength detection device when cleaning the fragments of the concrete test block.
[0034] During the detection, the control panel 11 can be operated to make the control panel 11 control the electric push rod 12 to work, so that the electric push rod 12 drives the pressure plate 13 to move downward, and the pressure plate 13 is guided by the guide rod 15. Subsequently, the pressure plate 13 squeezes the concrete test block until the concrete test block is broken, and the pressure at this time is monitored under the action of the pressure sensor 16, and the monitoring result is transmitted to the control panel 11, so as to realize the strength detection function of the strength detection device for the concrete test block, and finally complete the use of the strength detection device.
