Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixing, in particular to a concrete slump detection and adjustment device in a concrete transport vehicle. Background Art

[0002] As a mature technology, existing concrete has been widely used. With the advancement of science and technology, reinforced concrete has been widely used. Large-span bridges and high-rise buildings all use concrete. As an important indicator affecting the plasticization and pumpability of concrete, the slump of concrete has become increasingly important. If the slump of concrete is too large, it is easy to cause problems such as segregation, stratification, and poor workability. If the slump of concrete is too small, it is easy to cause problems such as poor fluidity. In actual construction, whether the slump of concrete is too large or too small, it will lead to problems such as difficult construction and insufficient strength of concrete.

[0003] At present, the concrete used on most construction sites is transported to the construction site by concrete transport trucks after being mixed at the mixing station. During the transportation process, in order to prevent the concrete from solidifying and segregating, the concrete mixer truck needs to continuously stir the concrete in the tank, and the slump of the concrete changes accordingly. The concrete transported to the site needs to undergo a secondary slump test, and the concrete that does not meet the slump requirements needs to be secondary mixed on site, all of which result in a huge waste of manpower and material resources.

[0004] Chinese patent announcement number CN208323815U, announcement date January 4, 2019, discloses a real-time monitoring and adjustment device for concrete slump in a concrete transport vehicle, which includes a speed measuring device installed at the front end of the mixing tank for measuring the flow rate of concrete, an adjustment device at the rear end of the mixing tank for adjusting the slump of concrete in the tank, and a display control device in the front of the vehicle for monitoring and control. The speed measuring device includes a water wheel that rotates with the flow of concrete in the mixing tank and a speed sensor on the water wheel axle. The adjustment device includes a regulating liquid tank at the rear end of the concrete truck seat for holding concrete slump regulating liquid, a metering tank fixedly installed on the upper side of the rear end of the mixing tank to control the amount of regulating liquid, and a spray device in the mixing tank for spraying regulating liquid. The display control device includes a speed display screen and a control panel. The problem that the slump cannot be monitored and adjusted in real time during concrete transportation is solved.

[0005] However, the detection process of the real-time monitoring and adjustment device for concrete slump in the concrete transport vehicle relies on a speed measuring device. However, the speed measuring device rotates with the flow of concrete in the mixing tank, and the speed measurement is often affected by the solidified concrete during previous use. As the use time goes by, the speed measurement becomes increasingly inaccurate, and the measurement error is large. Utility Model Content
