Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, and more specifically, to a concrete slump detection device. Background Art

[0002] The slump of concrete refers to the degree of deformation of concrete due to its own weight and fluidity at the construction site. Simply put, it measures the degree to which concrete collapses or flows downward due to its own gravity after the concrete is poured. Specifically, the slump is determined by measuring the collapse height of concrete under certain conditions, usually using an expansion funnel or other special measuring equipment. This height is called the slump. The slump of concrete is crucial to the construction process, so its slump needs to be tested.

[0003] After searching, a Chinese patent with announcement number CN218036839U discloses a concrete slump detection device. When the current concrete slump detection device is used, most of them are directly lifted upward by hand to separate the slump cylinder from the concrete mixture. However, the manual lifting method cannot accurately control the vertical upward movement of the slump cylinder. If the slump cylinder is tilted when being lifted, it will affect the slump detection data, thereby reducing the detection accuracy of the traditional concrete slump detection device. The transmission arm can be driven to move by shaking the handle along the second articulated seat. During the swinging process along the second articulated seat, the transmission arm controls the mounting ring to move linearly upward along the two groups of columns through the cooperation of the connecting rod and the first articulated seat, thereby driving the slump cylinder to move linearly upward quickly and lift it up, and the slump of the concrete is measured by the measuring component, effectively avoiding the tilt of the slump cylinder during the lifting process to affect the accuracy of the detection data.

[0004] After the concrete slump detection device is used for detection, concrete tends to accumulate inside the slump cylinder, which makes it inconvenient to clean the concrete inside the slump cylinder. At the same time, part of the concrete tends to adhere to the inner wall of the slump cylinder, which makes cleaning more troublesome and inconvenient to clean automatically. Utility Model Content

At the same time, the setting of the scale facilitates the measurement of slump and is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] As attached Figure 1-3 As shown, the bottom of the threaded rod 4 and the limiting slide bar 7 are both rotatably connected to the device base plate 1.
