[0003] An existing strength testing device for cement products (publication number: CN221007076U) has at least the following drawbacks: the device achieves compressive strength testing of cement products by setting a test weight to fall, but in the strength testing of cement products, it is also necessary to test the flexural strength of cement products. However, the device can only achieve compressive strength testing of cement products, resulting in a single testing function. Therefore, this utility model is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cement product strength testing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figures 1-5As shown, a cement product strength testing device includes a testing platform 1. A testing component is provided on the top surface of the testing platform 1. The testing component includes a top frame 2 fixed to the top surface of the testing platform 1. A pressure plate 201 is provided below the top frame 2. Two drive holes 202 are opened on the top surface of the testing platform 1. Two support rods 203 are provided inside the drive holes 202. A drive screw 204 is rotatably connected to the bottom surface of the support rod 203. A threaded sleeve 205 is threadedly connected to the outer wall of the drive screw 204. A fixing strip 206 is fixed to the bottom surface of the threaded sleeve 205.

[0024] like Figures 1-5 As shown, in this embodiment, a hydraulic rod 207 is fixed to the top surface of the testing platform 1. The hydraulic rod 207 is electrically connected to an external electro-hydraulic servo system. The telescopic end of the hydraulic rod 207 extends through to the bottom surface of the testing platform 1 and is fixed to the top surface of the pressure plate 201. A first square hole 208 is opened on the top surface of the drive screw 204. A first square rod 209 is slidably inserted into the first square hole 208. A first gear is fixed to the bottom end of the first square rod 209. The first gear is rotatably connected to the top surface of the fixing strip 206. By placing the cement product on the top surface of the testing platform 1, the hydraulic rod 207 is activated to drive the pressure plate 201 to apply pressure to the cement product. The pressure of the hydraulic rod 207 is controlled by the electro-hydraulic servo system of the hydraulic rod 207, thereby testing the cement product. After the pressure test, the first motor is activated to drive the support rod 203 to lift the cement product. The two support rods 203 support the cement product from two points at the bottom. Then, the hydraulic rod 207 is activated again to drive the pressure plate 201 to apply pressure to the cement product, thereby realizing the three-point bending test of the cement product. This allows for separate testing of the compressive strength and bending strength of the cement product, making the device more functional.

[0025] like Figures 1-5As shown, in this embodiment, a second gear is rotatably connected to the top surface of the fixing strip 206, and the second gear meshes with the first gear. A first bevel gear is fixed to the top surface of the second gear. A connecting plate 3 is fixed to the top surface of the fixing strip 206, and a second bevel gear is rotatably connected to one side of the connecting plate 3. The first bevel gear meshes with the second bevel gear. Support plates 301 are fixed to the inner bottom surface of the detection platform 1 near both the left and right sides. A second square rod 302 is rotatably connected between the two support plates 301. The second square rod 302 is slidably inserted into the second bevel gear. A first motor is fixed to the right side of the support plate 301 near the right side of the detection platform 1. The output shaft of the first motor is fixed to one end of the second square rod 302. By setting a second motor to drive the second square rod 302 to rotate, the second bevel gear drives the first bevel gear to rotate, and the second gear drives the first gear to rotate, thereby realizing the rotation of the first square rod 209. The first square rod 209 drives the drive screw 204 to rotate, and with the drive screw 204 threadedly connected to the threaded sleeve 205, the drive screw 204 drives the support rod 203 to lift the cement product.

[0026] like Figures 1-5 As shown, in this embodiment, a bidirectional lead screw 4 is rotatably connected between the two support plates 301. The fixing strip 206 is threadedly connected to the outer wall of the bidirectional lead screw 4. A second motor is also fixed on the right side of the support plate 301 near the right side of the testing table 1. One end of the output shaft of the second motor is fixed to one end of the bidirectional lead screw 4. The second motor drives the bidirectional lead screw 4 to rotate. Under the action of the two fixing strips 206 and the outer wall of the bidirectional lead screw 4, the two fixing strips 206 drive the two support rods 203 to move closer or further away from each other, thereby adjusting the support position of the support rods 203 according to the size of the cement product, increasing the applicability of the device.

[0027] like Figures 1-5 As shown in this embodiment, two support rollers 5 are fixed on the bottom surface of the fixing strip 206. The support rollers 5 abut against the inner bottom surface of the testing table 1. By setting the support rollers 5, the support rollers 5 can play an auxiliary support role for the fixing strip 206, preventing the pressure of the fixing strip 206 from being directly applied to the bidirectional lead screw 4 during the bending test, which would cause the bidirectional lead screw 4 to bend and be damaged.

[0028] like Figures 1-5As shown, in this embodiment, two first limiting rods 6 are fixed to the top surface of the pressure plate 201. The first limiting rods 6 are slidably inserted into the bottom surface of the top frame 2. Two second limiting rods 601 are fixed between the two support plates 301. The fixing strip 206 is slidably inserted into the outer wall of the second limiting rods 601. Two telescopic rods 602 are fixed to the top surface of the fixing strip 206. The telescopic ends of the telescopic rods 602 are fixed to the bottom surface of the support rod 203. The first limiting rods 6 can limit the pressure plate 201, the second limiting rods 601 can limit the fixing strip 206, and the telescopic rods 602 can limit the support rod 203, making the pressure plate 201, fixing strip 206, and support rod 203 more stable when moving.

[0029] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, the cement product is placed on the top surface of the testing platform 1, and then the hydraulic rod 207 is started to drive the pressure plate 201 to apply pressure to the cement product. The pressure of the hydraulic rod 207 is controlled by the electro-hydraulic servo system of the hydraulic rod 207, thereby testing the cement product. After the pressure test, the second motor is started to drive the bidirectional lead screw 4 to rotate. Under the action of the two fixing bars 206 and the outer wall threaded connection of the bidirectional lead screw 4, the two fixing bars 206 drive the two support rods 203 to move closer or further away from each other, thereby adjusting the support position of the support rods 203 according to the size of the cement product. During this process, the second bevel gear slides on the outer wall of the second square rod 302. Then the first motor is started to drive the second square rod 302 to rotate, and the second square rod 302 drives the second bevel gear to rotate. Under the meshing action of the first bevel gear and the second bevel gear, the first bevel gear rotates synchronously and drives the second gear to rotate. In this process, the first gear rotates synchronously, driving the first square rod 209 to rotate. The first square rod 209 then drives the drive screw 204 to rotate. Under the threaded connection between the drive screw 204 and the threaded sleeve 205, the support rod 203 moves upward, lifting the cement product. During this process, the drive screw 204 slides on the outer wall of the first square rod 209. Subsequently, the hydraulic rod 207 is activated to drive the pressure plate 201 to apply pressure to the cement product, thereby achieving a three-point bending test on the cement product. This is achieved by setting support rollers 5. The support roller 5 provides auxiliary support for the fixing strip 206, preventing the pressure of the fixing strip 206 from being directly applied to the bidirectional lead screw 4 during bending tests, which could cause the bidirectional lead screw 4 to bend and be damaged. The first limiting rod 6 can limit the pressure plate 201, the second limiting rod 601 can limit the fixing strip 206, and the telescopic rod 602 can limit the support rod 203, making the pressure plate 201, fixing strip 206, and support rod 203 more stable when moving.
