[0002] Concrete refers to artificial stone made with cement as the main binder, combined with water, sand, gravel, and optionally chemical admixtures and mineral admixtures, in appropriate proportions, through uniform mixing, dense forming, and curing and hardening. Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, namely fresh concrete or concrete mixture; the hard state after hardening, namely hardened concrete or concrete. The concrete strength grade is divided according to the standard value of cube compressive strength. The strength grades of ordinary concrete in China are divided into 14 levels: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75, and C80. After the concrete is formed, it needs to be subjected to force analysis and detection.

[0003] In the prior art, when in use, the concrete block to be detected is placed in the detection box, and an electric push rod is used to drive a pressure sensor to extrude it, and the pressure strength that it can bear is determined by observing the data of the pressure sensor.

[0004] However, in actual use, due to the large hardness of the concrete, when the electric push rod drives the pressure sensor to extrude the concrete block, it will cause the power of the electric push rod to be insufficient, resulting in inaccurate data of the pressure sensor.

For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are well-known techniques in this field. The following mainly introduces the working principle and process.

The bottom of the mounting frame 4 is fixedly connected to the top of the base 1. The model of the pressure sensor 10 is not limited.

[0027] In the specific implementation process, it is particularly worth noting that with the cooperation of the mounting plate 2, the pressure sensor 10 and the lifting plate 8, the concrete block is placed in the placement box 3, and through the movement of the lifting plate 8, the pressure sensor 10 squeezes the concrete block to measure the pressure it can withstand.

[0028] Furthermore, the mounting frame 4 is rotatably connected to a threaded rod 7 through a bearing. A sleeve 20 is movably connected to the outer wall of the threaded rod 7. The outer wall of the sleeve 20 is slidably clamped to the inner wall of the mounting frame 4. The outer wall of the sleeve 20 is fixedly connected to the outer wall of the lifting plate 8.

[0029] In the specific implementation process, it is particularly worth noting that with the cooperation of the threaded rod 7, the mounting frame 4 and the sleeve 20, by rotating the threaded rod 7, using the meshing of the threaded rod 7 and the sleeve 20, the sleeve 20 is lifted or lowered, driving the lifting plate 8 to move, so that the pressure sensor 10 squeezes the concrete block in the placement box 3.

[0030] Furthermore, a driven gear 15 is fixedly connected to a section of the threaded rod 7 extending into the mounting frame 4. A driving gear 14 is meshed with the outer wall of the driven gear 15. A driving rod 6 is fixedly connected to the outer wall of the driving gear 14.

[0031] In the specific implementation process, it is particularly worth noting that with the cooperation of the driving rod 6, the driving gear 14 and the driven gear 15, by rotating the driving rod 6, the driving gear 14 drives the driven gear 15 to rotate, and drives the threaded rod 7 to rotate, so that the lifting plate 8 drives the pressure sensor 10 to lift or lower.

[0032] Specifically, when using this device for detecting the concrete strength of a house, the concrete block is placed in the placement box. By rotating the driving rod 6, the driving gear 14 drives the driven gear 15 to rotate, and drives the threaded rod 7 to rotate through the driven gear 15, so that the sleeve 20 drives the lifting plate 8 to lift or lower, thereby enabling the pressure sensor 10 to squeeze the concrete block and measure the bearing pressure of the concrete.

[0033] Embodiment 2: Consisting of Figures 1-5It can be seen that a servo motor 5 is fixedly connected to the top of the mounting frame 4.

The bottom of the telescopic column 17 is fixedly connected to a fixing plate 11;

[0036] In the specific implementation process, it is particularly worth noting that, under the cooperation of the fixing plate 11, the telescopic column 17 and the fixing block 16, when the pressure sensor 10 moves downward, it will drive the fixing plate 11 to move, so that the fixing plate 11 squeezes the concrete block, and the telescopic column 17 squeezes the spring 18. Using the elastic force of the spring 18, the telescopic column 17 supports the fixing plate 11, thereby supporting the concrete block to prevent it from moving;

[0037] Furthermore, a mounting block 9 is fixedly connected to the bottom of the lifting plate 8. The bottom of the mounting block 9 is fixedly connected to the top of the pressure sensor 10. A limiting column 12 is movably connected to the inner wall of the lifting plate 8. The outer wall of the limiting column 12 is fixedly connected to the top of the base 1;

[0038] In the specific implementation process, it is particularly worth noting that, under the cooperation of the limiting column 12, the mounting block 9 and the lifting plate 8, when the lifting plate 8 moves, the limiting column 12 will make it move more stably, and the pressure sensor 10 is supported through the mounting block 9;
