Abstract
Description
Technical Field

[0002] Concrete is a widely used material in construction engineering, and the stability and reliability of its performance are crucial to the quality of the project. Among them, the setting time of concrete is one of the important indicators for measuring its performance. The speed of setting time not only affects the workability of concrete, but also directly relates to the progress and quality of the project. Therefore, accurate and rapid determination of the setting time of concrete is of great significance to engineering practice.
[0003] Chinese Patent Publication No. CN221745804U discloses a concrete mixture setting time tester, relating to the field of concrete testing technology. The tester includes a base and a mold installed on the base. The mold is filled with concrete. A pair of hydraulic push rods are installed on the base, with pressure plates installed at the ends of the hydraulic push rods. The pressure plates are vertically aligned with the mold. An adjustment and detection component is installed on the pressure plate. The specific detection position is controlled by adjusting the detection component. This invention, by setting up the adjustment and detection component, allows for the pushing of internal push blocks. The movement of the push blocks causes the auxiliary measuring probes at the bottom to move outward. Four auxiliary measuring probes can complete the detection of the outer layer of concrete, while the main measuring probe can complete the detection of the inner layer of concrete. The combination of auxiliary and main measuring probes achieves the detection purpose and improves the accuracy of the detection, making it suitable for widespread promotion and use.
[0004] However, this utility model has the following problems in actual use:

In this embodiment, the structure of the concrete mixture setting time tester is improved to make it easier to prevent the need for workers to manually press down the probe and to replace and clean the probe.
[0028] Example 1:
[0029] Please see Figure 1 and Figure 2 To facilitate easier control of the measuring instrument body 1 by staff, it includes a detachable upright rod 2 connected to the upper end of the measuring instrument body 1, a base 8 fixedly installed at the lower end of the measuring instrument body 1 for support, a dial 9 fixedly installed on the side of the measuring instrument body 1 for detection, a button 10 fixedly installed on the side of the measuring instrument body 1 for control, a display screen 11 fixedly installed on the side of the measuring instrument body 1, a disc 12 fixedly connected to the lower end of the upright rod 2 for positioning, and a bolt 13 for fixing inserted into the upper end of the disc 12.
[0030] The base 8 provides support for the main body 1 of the measuring instrument, further ensuring overall stability.

The disc 12 and bolt 13 can more firmly fix the upright 2 to the upper part of the main body 1 of the measuring instrument, further ensuring the stability of the upright 2.
[0031] Example 2:
[0032] Please see Figures 1 to 5 In order to fix the carrier plate 3 that is stuck on the surface of the upright 2 and to make it easier to fix the sleeve 5 more stably to the lower end of the air pump 4, the outer surface of the upright 2 is fitted with a carrier plate 3 for positioning. The upper end of the carrier plate 3 is detachably connected to the air pump 4, and the lower end of the air pump 4 is detachably connected to the sleeve 5 for positioning. The inside of the sleeve 5 is fitted with a probe 6 for detection. The upper end of the carrier plate 3 is provided with a positioning hole 14.

[0036] By using the pin 19, the cylinder 7 can be more stably fixed to the upper end of the measuring instrument body 1, further ensuring that the cylinder 7 will not shake when testing the concrete mixture.
[0037] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

Second, install the cylinder 7 on the upper part of the main body 1 of the measuring instrument and fix it with the pin 19. Next, evenly place the concrete mixture inside the cylinder 7, ensuring that the sample to be tested is sufficient and evenly distributed. Then, turn on the air pump 4, and use the pressure generated by the air pump 4 to press the sleeve 5 and the probe 6 into the concrete mixture. During this process, observe and record the time required for the probe 6 to be pressed to a certain depth. This time is the setting time of the concrete mixture. At the same time, the test results and related information can be viewed in real time through the display screen 11. Finally, after the test is completed, turn off the air pump 4 and remove the sleeve 5 and the probe 6 from the concrete mixture. Clean and maintain the sleeve 5 and the probe 6 for the next use. At the same time, remove the cylinder 7 from the main body 1 of the measuring instrument and clean the residue inside.
