Description

Technical Field

[0001] This utility model belongs to the technical field of testing devices, specifically a cement compressive strength testing device. Background Technology

[0002] After cement production, a compressive strength test is required to determine whether the cement quality is up to standard. CN219625238U discloses a cement compressive strength testing device that adjusts the positions of the pressure mechanism and multi-point detection mechanism using a horizontal adjustment component. The pressure mechanism then operates, causing the pressure platform to press down, and multiple pressure detection components on the lower surface of the platform press against the outer surface of the cement block. The pressure mechanism continuously applies pressure to the platform, and the pressure data is detected by the multiple pressure detection components, thus enabling better multi-point testing of the cement. However, this testing device lacks a protective structure during testing, which could lead to cement fragments flying out when the cement cracks, affecting safety. Furthermore, the cement fragments generated after testing are difficult to clean. Therefore, this application proposes a cement compressive strength testing device. Utility Model Content

[0023] The cement placement platform 2 supports and places the cement block, the protective sleeve 3 provides safety protection during the compressive strength test to prevent cement fragments from flying out, and the hydraulic rod 4 can drive the pressure seat 5 to press down to achieve the compressive strength test of the cement.

[0024] The cement placement platform 2 consists of a central pressure-bearing support 7, a square frame 8, four connecting seats 9, and four flow guides 10. The central pressure-bearing support 7 is fixedly connected to the middle position of the bottom of the support frame 1. The square frame 8 is located at the top of the outer side of the central pressure-bearing support 7. The four connecting seats 9 are all fixedly connected between the central pressure-bearing support 7 and the square frame 8. The four flow guides 10 are respectively fixedly connected to the four sides of the bottom of the square frame 8 and connected to the four sides of the central pressure-bearing support 7. The central pressure-bearing support 7, the square frame 8, and the four connecting seats 9 form several discharge troughs 11 that communicate with the four flow guides 10.

[0025] During the cement compressive strength test, the cement block will break. After the test is completed, the larger cement block is taken out directly. The cement debris on the top of the central pressure support 7 is swept away with a broom or other tools so that the cement debris falls into the inside of the discharge chute 11 and is discharged through the four guide hoods 10. Then, a receiving box or trash can is placed at the bottom of the four guide hoods 10 to collect the cement debris.

[0026] The vertical cross-sections of the four connecting seats 9 are all isosceles triangular structures, which facilitates the full discharge of cement residue;

Locking knobs 17 are provided in the middle of both sides of the support frame 1, and the locking knobs 17 are threadedly connected to the support frame 1.
