Description

Technical Field

[0001] This utility model relates to the field of cement product technology, specifically to a cement product strength testing device. Background Technology

[0002] Cement products refer to various products made by mixing cement as a binder with aggregates such as sand and stone or other materials and processing them through certain processes. They are widely used in construction, road and water conservancy projects.

[0003] Traditional technologies have shortcomings. During the testing process, it is difficult to ensure that the loading head applies pressure to the cement product vertically and stably, which makes it impossible to accurately simulate the actual stress scenario, resulting in large testing errors. In addition, the operation process is cumbersome and the testing efficiency is low. For example, adjusting the position of the testing components is time-consuming, and the cleaning and preparation for the next test after the test are complicated. To address these issues, we have proposed a cement product strength testing device. Utility Model Content

[0039] Drive motor 8: mounted on the placement platform at the front end of support frame 12, its output shaft is connected to threaded rod 9, providing power for the rotation of threaded rod and driving the protective cover 4 to move;

[0040] Threaded rod 9: It is fixedly connected to the output shaft of the drive motor 8 and threadedly engaged with the threaded bushing 10 on the guide plate 11. It drives the guide plate 11 and the protective cover 4 to move by rotating.

[0041] Threaded bushing 10: It is snapped into the slot in the center of the guide plate 11 and is threaded with the threaded rod 9, converting the rotation of the threaded rod into the linear movement of the guide plate and the protective cover.

[0042] Guide plate 11: It is inserted between two movable plates 17, and is fixed at both ends with nuts. The center is snapped with threaded bushing 10, which can guide the protective cover 4 to move stably and ensure accurate pressure application.

[0043] Support frame 12: This is the basic support structure of the equipment, which is equipped with components such as drive motor 8, and has a testing platform 13 on top, providing support and stability for the entire testing process;

[0044] Testing platform 13: Located on top of support frame 12, it is used to place cement products to be tested, providing a stable placement platform for testing and ensuring smooth testing.

[0050] Connecting block 19: Fixed at both ends of guide plate 11, corresponding to the connecting hole 18 on moving plate 17, and fixed by threaded post and nut to enhance the structural connection stability.

[0051] Working Principle: In the preparation stage, the cement product to be tested is placed stably on the testing platform 13 on top of the support frame 12. At this time, the drive motor 8 at the front end of the support frame 12 is started. The output shaft of the drive motor 8 drives the threaded rod 9 to rotate. Since the threaded rod 9 is threadedly engaged with the threaded bushing 10 on the guide plate 11, and the two ends of the guide plate 11 are fixed between the moving plates 17 at the bottom ends of the protective cover 4 by nuts, the rotation of the threaded rod 9 will drive the guide plate 11 to slide the protective cover 4. During the sliding process, the rollers 7 in the mounting parts 16 on both sides of the bottom of the protective cover 4 roll along the roller strips 14 on both sides of the top of the support frame 12. At the same time, the moving plates 17 inside the two ends of the protective cover 4 slide in the guide holes 15 of the support frame 12 to ensure the smooth sliding of the protective cover 4. When the clamp 5 on the front end of the protective cover 4 is engaged with the clamping column 6 on the top of the support frame 12, the drive motor 8 is stopped. At this time, the equipment... After preparation, the cement product is secured in the testing position. During the pressure application phase, the hydraulic cylinder 1 at the top of the protective cover 4 is activated, and the piston shaft of the hydraulic cylinder 1 extends, causing the fixed plate 2 and the loading head 3 at the bottom of the fixed plate 2 to descend together. The loading head 3 gradually contacts and applies pressure to the cement product. As the piston shaft of the hydraulic cylinder 1 continues to extend, the pressure applied by the loading head 3 continuously increases, thus applying pressure to the cement product to simulate the stress situation in actual use. During the data processing phase, when the cement product is damaged under pressure, the pressure data of the hydraulic cylinder 1 at this time is recorded. Through the algorithm preset by the equipment and combined with various parameters of the equipment, the strength value of the cement product is calculated. After the test is completed, the drive motor 8 is started in reverse, causing the threaded rod 9 to reverse and drive the protective cover 4 to slide back to the initial position, releasing the clamp 5 from the clamping column 6, and removing the tested cement product debris to prepare for the next test.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
