[0002] Concrete refers to the general term of engineering composite materials that cementitious materials bond aggregates into a whole. Generally, it refers to cement concrete obtained by mixing cement as the cementitious material, sand and stone as aggregates with water in a certain proportion. Concrete is a raw material commonly used in modern construction projects. The strength of building concrete determines the safety and service life of the building, and it is necessary to detect the compressive strength of concrete through a concrete strength detection device.

[0003] In the prior art, when detecting the strength of concrete, most use a hydraulic press to apply force to a concrete precast block, and then a pressure sensor receives the pressure exerted on the concrete precast block, so as to achieve the purpose of detecting the concrete precast block. However, when the concrete reaches the limit of the pressure it can withstand, the concrete precast block will instantly break and collapse, resulting in some debris flying everywhere, and even causing harm to the human body. At the same time, the flying concrete fragments also need to be cleaned to avoid unevenness on the surface of the detection platform during subsequent detections, which will affect the detection effect of other concrete blocks.

[0004] Therefore, a concrete strength detection experiment device is needed to solve the problems of harm to personnel caused by the collapse of concrete and the need to manually clean the detection platform in the prior art. Content of the Utility Model

Specific embodiments

[0022] The following further describes the utility model in conjunction with embodiments.

[0023] Please refer to Figures 1-4 , the utility model provides a concrete strength detection experiment device, including an operation platform 1, brackets 2 are fixed at the four corners of the top end of the operation platform 1, a top frame 3 is fixedly connected to the tops of the brackets 2, a pressure sensing display 4 is fixed on the outer wall of one side of the top frame 3, a servo cylinder 5 is fixed at the center of the top end of the top frame 3, a pressure plate 7 is fixed at the bottom of the driving end of the servo cylinder 5, a connecting frame 8 is fixed on the outer wall of the driving end of the servo cylinder 5, and cleaning mechanisms 9 are arranged at both ends of the outer wall of the connecting frame 8;

[0024] A stress platform 6 is installed at the center of the top end of the operation platform 1, and a protection mechanism 13 is fixed at the center of the bottom end of the connecting frame 8.

[0025] When the cleaning mechanism 9 starts the servo cylinder 5, it can drive the rotating frame 91 to be stressed through the connecting frame 8, so as to realize rotational stress, and further drive the cleaning roller 92 and the cleaning shovel 93 to move, thereby cleaning the sundries on the surface of the operation platform 1. At the same time, when the cleaning shovel 93 slides to one end of the opening 11, the sundries fall into the inner wall of the collection box 12, so as to achieve the effect of cleaning and collection.

[0026] The protection mechanism 13 can mainly realize that when the concrete is stressed and extruded, the stress spring 132 first contacts the surface of the operation platform 1, so as to protect the concrete block. At the same time, through the action of the protection box 131, it can drive the protection box 131 to be stressed. While ensuring that the stress spring 132 is attached to the surface of the operation platform 1, the pressure plate 7 can also stress the concrete, so as to detect the strength of the concrete through the stress platform 6, and the strength detection can be displayed through the pressure sensing display 4.

[0027] Furthermore, as Figure 2As shown, it is worth specifically stating that the cleaning mechanism 9 includes a plurality of rotating frames 91, and the plurality of rotating frames 91 are respectively rotatably installed at both ends of the outer wall of the connecting frame 8. At the bottom ends of the rotating frames 91, corresponding cleaning rollers 92 are respectively rotatably installed. A cleaning shovel 93 is rotatably installed between the cleaning roller 92 and the rotating frame 91. Limiting wheels 94 are rotatably installed at both ends of the cleaning roller 92.

[0028] When force is applied through the connecting frame 8, it can drive the rotating frame 91 to rotate, and then can drive the cleaning roller 92 and the cleaning shovel 93 to move. Thus, it can clean the concrete debris on the surface of the operation platform 1. And through the limiting wheels 94, it can mainly limit the movement of the cleaning roller 92 and the cleaning shovel 93, thereby improving the effect of cleaning concrete debris. At the same time, through the action of the opening 11 and the collection box 12, it can collect the cleaned concrete fragments.

[0029] Furthermore, as shown in Figure 1 、 Figure 2 it is worth specifically stating that limiting chutes 10 are provided at both the front and rear ends of the operation platform 1, and the limiting wheels 94 are installed in a limited movement manner on the inner wall of the limiting chutes 10.

[0030] This solution has the following working process: When it is necessary to conduct a strength stress test on the concrete, first start the servo cylinder 5, which can drive the connecting frame 8 and the rotating frame 91 to be stressed, and then drive the cleaning roller 92 and the cleaning shovel 93 to move, so as to clean the debris on the surface of the stress platform 6. At the same time, the rotating frame 91 slides out of the surface of the stress platform 6, then pause the servo cylinder 5, and then place the concrete block on the surface of the stress platform 6. Then start the servo cylinder 5 again, so that the stress spring 132 first fits with the surface of the operation platform 1. Further, through the pressure plate 7, it can stress the concrete surface, and then through the pressure sensor display 4 and the stress platform 6, the concrete is subjected to pressure detection. At the same time, when the stress spring 132 is stressed, the protective box 131 can drive the stress spring 132 to move on the outer wall of the driving end of the servo cylinder 5, thus avoiding interference with the pressure detection device. At the same time, the cleaning roller 92 and the cleaning shovel 93 move to one end of the opening 11, so as to clean and collect the debris on the surface of the operation platform 1.

[0031] According to the above working process, it can be seen that the cleaning roller 92 can mainly clean the remaining dust on the surface of the operation platform 1, and the cleaning shovel 93 can mainly clean the larger concrete fragments, thus eliminating the need for manual cleaning and improving the practical effect of the equipment.

[0032] Furthermore, as shown in Figure 1 、 Figure 2 、Figure 3 As shown, it is worth specifically noting that the protection mechanism 13 further includes a protection box 131. The protection box 131 is fixedly installed at the center of the bottom end of the connecting frame 8 and sleeved on the outer wall of the driving end of the servo cylinder 5. A force-bearing spring 132 is fixed to the bottom end of the protection box 131.

[0033] The protection box 131 can mainly enable the force-bearing spring 132 to be actively stressed while being stressed, thereby avoiding interference with pressure detection.

[0034] Further as Figure 1 、 Figure 3 shown, it is worth specifically noting that the force-bearing spring 132 is movably installed on the outer wall of the driving end of the servo cylinder 5.

[0035] Further as Figure 1 、 Figure 4 shown, it is worth specifically noting that openings 11 are provided on both sides of the operation platform 1, and collection boxes 12 are fixedly installed at both ends of the operation platform 1. The openings 11 communicate with the collection boxes 12.

[0036] Further as Figure 1 、 Figure 4 shown, it is worth specifically noting that the pressure sensing display 4 is electrically connected to the force-bearing platform 6, and support legs 14 are fixed at the four corners of the bottom end of the operation platform 1.

[0037] When the concrete is under a large pressure, the force-bearing platform 6 can sense it, and then the pressure sensing display 4 can display the pressure of the concrete.

[0038] In summary: When the cleaning mechanism 9 starts the servo cylinder 5, it can drive the rotating frame 91 to be stressed through the connecting frame 8, thereby realizing rotational stress. Further, it can drive the cleaning roller 92 and the cleaning shovel 93 to move, thereby realizing the cleaning of the sundries on the surface of the operation platform 1. At the same time, when the cleaning shovel 93 slides to one end of the opening 11, the sundries fall into the inner wall of the collection box 12, thus achieving the effect of cleaning and collection. The protection box 131 can mainly enable the force-bearing spring 132 to be actively stressed and extruded while being stressed, thereby enabling the force-bearing spring 132 to protect the concrete while bearing the force of the concrete, preventing the concrete from being shattered under a large pressure and causing harm to the detection personnel.

[0039] The servo cylinder 5 can be purchased on the market. The servo cylinder 5 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
