Description

Technical Field

[0001] This invention relates to the field of concrete setting time measuring instruments, and in particular to a fully automatic concrete setting time measuring instrument. Background Technology Concrete setting time is a key indicator for evaluating the workability and structural strength development of concrete. Its determination is mainly based on the penetration resistance method, which measures the resistance of concrete mixtures at different ages to a standard penetration needle to determine the initial and final setting times. In the field of construction engineering, accurate determination of setting time is crucial for determining the timing of concrete pouring, formwork removal, and curing procedures, directly affecting project progress and structural safety. With the development of modern buildings towards high-rise and large-span structures, the strength level of concrete is constantly increasing and the composition is becoming more complex. Traditional manual measurement methods can no longer meet the requirements of high-precision and high-efficiency testing, and fully automatic concrete setting time testers have emerged to meet this need.

[0002] A search revealed Chinese Patent Publication No. CN221007591U, which discloses a fully automatic cement mortar and concrete setting time tester. This tester includes a sample stage, a frame, a probe displacement system, a probe switching system, a sample stabilizing device, a horizontal adjustment device, a probe cleaning device, and a constant temperature circulating water device. The probe displacement system allows the probe to move arbitrarily horizontally and vertically. The probe switching system allows for rotatable switching between vertically moving and rotating probes. Through the probe displacement system and the probe switching system, the setting time of cement mortar and concrete samples placed on any sample stabilizing device can be automatically measured. The instrument is automatically cleaned after each measurement, and this process is repeated. In addition, the leveling device can accommodate the horizontal placement of the measuring instrument in complex terrain, and the constant temperature circulating water device can provide a constant measurement temperature, making the measurement results more accurate. However, the above process requires the use of an external mixer to pre-mix the concrete, and then the mixture is manually transferred to the mold of the measuring instrument. During this process, the consistency of the mixture is prone to change due to thixotropic effect between the time the mixing is completed and the time it is poured into the mold, resulting in local thickening and reduced leveling properties. At the same time, the difference in impact force when manually pouring the mixture can lead to uneven distribution of aggregate, causing an imbalance in the paste-aggregate ratio in different areas of the mold. Summary of the Invention

[0003] To achieve the above objectives, the present invention adopts the following technical solution: a fully automatic concrete setting time tester, comprising a base plate, wherein a detection mechanism is fixedly connected to the top rear side of the base plate, the detection mechanism being used to test the concrete setting time, and a protective mechanism is fixedly connected to the top front side of the base plate, the protective mechanism being used to protect the concrete mixing test.

These connecting plates not only provide support and fixation but also offer additional structural stability to the entire connecting assembly. Specifically, a limiting sleeve is further fixedly connected to the inner wall of the connecting plate located on the front side.

At the same time, the threaded shaft 3041, which is threaded to the inner wall of the limiting sleeve 3032, can move left and right while being limited to rotation on the inner wall of the limiting sleeve 3032. This allows the semi-circular clamp 3042, which is rotatably connected to the outer wall of the threaded shaft 3041, to clamp and position the measuring barrel 302, preventing excessive shaking during stirring and ensuring measurement accuracy.
