[0002] In the field of concrete engineering, current concrete parameter testing technologies are widely used on construction sites and in laboratories, especially in evaluating the workability of concrete. Slump is a key indicator for evaluating the fluidity and workability of concrete, and it has a significant impact on ensuring that concrete can be poured smoothly and compacted. Inverted slump, on the other hand, is another way to evaluate the fluidity of concrete under certain special construction conditions, which helps to provide a more comprehensive understanding of the workability of concrete.

[0003] However, in concrete parameter testing scenarios, existing equipment requires the use of different devices to test slump and inverted slump, which greatly increases the complexity of operation, the complexity of the test, and the time cost. Furthermore, data deviations may occur due to environmental changes and differences in measuring devices, affecting the accuracy and reliability of concrete quality control. In addition, differences in precision between different devices may lead to inconsistent test results, which in turn affects the accuracy of the results. Utility Model Content

[0021] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale; for example, the thickness or width of some layers may be exaggerated relative to other layers.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0023] like Figures 1-3 As shown, it includes a support frame 1 and a slump cylinder 2 installed on the inner wall of the support frame 1. A slump assembly 3 is installed on the outer wall of the slump cylinder 2 for quick installation and disassembly of the slump cylinder 2, so that it can adapt to different types of slump tests and quickly replace or adjust the slump cylinder 2.

[0024] like Figures 1-3As shown, in order to quickly install and disassemble the slump cylinder 2 and adapt it to different types of slump tests, and to quickly replace or adjust the slump cylinder 2, a slump assembly 3 is installed on the top of the outer wall of the slump cylinder 2. Specifically, the slump assembly 3 includes a placement plate 301, which is placed on the outer wall of the slump cylinder 2. The bottom end of the placement plate 301 is provided with a guide plate 303. The top end of the support frame 1 is provided with a limiting hole 308, which is slidably connected to the guide plate 303. The top outer wall of both the placement plate 301 and the support frame 1 is provided with a fixing groove 304. The bottom end of the inner wall of the fixing groove 304 is rotatably connected to a fixing rod 306. The other end of the fixing rod 306 is provided with a screw rod, and the outer wall of the screw rod is rotatably connected to a fixing sleeve 307. The top end of the placement plate 301 is... The slump cylinder 2 has a lifting hole 302, a positioning strip 305 at one end, and a fixing plate 309 fixedly connected to the outer wall of the support frame 1. A positioning groove 310 is located at the center of the top of the fixing plate 309, which is compatible with the positioning strip 305. A material discharge hole 311 is located at the bottom of the inner wall of the positioning groove 310. A rotating shaft 315 is located at the bottom of the fixing plate 309, and a sealing plate 314 is rotatably connected to the outer wall of the rotating shaft 315. An installation plate 313 is located on the outer wall of the sealing plate 314, and an installation groove 312 is slidably connected to the installation plate 313. The installation groove 312 is located on one side of the outer wall of the installation block, and the installation block is located at the bottom of the fixing plate 309. It should be noted that in this embodiment, when conducting a concrete slump test, the slump cylinder 2 is placed on the ground, filled with concrete, and then... The test is completed by lifting the slump cylinder 2 through the lifting hole 302. If an inverted slump test is required, rotate the slump cylinder 2 180° so that the guide plate 303 at the bottom of the placement plate 301 aligns with the limiting hole 308 and slides in. During sliding, the positioning strip 305 slides into the positioning groove 310, ensuring a tight fit between the bottom of the placement plate 301 and the top of the support frame 1. The design of the guide plate 303 and the limiting hole 308, and the positioning strip 305 and the positioning groove 310, ensures the accuracy of the slump cylinder 2's placement on the support frame 1, avoiding test errors caused by positional deviations. Then, push the fixing rod 306 to rotate the fixing sleeve 307 to the top of the placement plate 301. Finally, rotate the fixing sleeve 307 on the outer wall of the screw rod so that the bottom of the fixing sleeve 307 aligns with the top of the placement plate 301. The top of the plate 301 is attached to the inner wall of the support frame 1, thus fixing the slump cylinder 2 to the inner wall of the support frame 1. This ensures the stability of the slump cylinder 2 during the test. After filling with concrete, the handle on the outer wall of the sealing plate 314 is pushed, causing the sealing plate 314 to rotate along the outer wall of the rotating shaft 315. During rotation, the mounting plate 313 slides out of the mounting groove 312, and the sealing plate 314 moves away from the bottom of the discharge hole 311, allowing the concrete cylinder discharge hole 311 to fall. This enables the inverted slump test, allowing the slump cylinder 2 to be quickly switched between upright and inverted test modes. This reduces the preparation work before the test and the operation steps during the test, improves the test efficiency, and avoids the influence of factors such as the size error and surface roughness difference of different instruments on the test results.This ensures the consistency and comparability of slump and inverted slump data, facilitating a more accurate evaluation of concrete mix performance. If slump cylinder 2 needs to be disassembled for a standard slump test, the above steps can be reversed to disassemble it. This also facilitates equipment cleaning and maintenance, preventing concrete residue from solidifying inside the equipment.

[0025] When a slump or inverted slump test is required for concrete, the slump cylinder 2 is placed on the ground, filled with concrete, and then lifted through the lifting hole 302 to complete the test. For an inverted slump test, the slump cylinder 2 is rotated 180° so that the guide plate 303 at the bottom of the placement plate 301 is aligned with the limiting hole 308 and slid in. During sliding, the positioning strip 305 slides into the positioning groove 310, ensuring that the bottom of the placement plate 301 is tightly fitted to the top of the support frame 1. Then, the fixing rod 306 is pushed to rotate the fixing sleeve 307 to the top of the placement plate 301. Finally, the fixing sleeve 307 on the outer wall of the screw is rotated so that the bottom of the fixing sleeve 307 is fitted to the top of the placement plate 301. This fixes the slump cylinder 2 to the inner wall of the support frame 1, ensuring its stability during the test. After filling with concrete, push the handle on the outer wall of the sealing plate 314 to rotate the sealing plate 314 along the outer wall of the rotating shaft 315. During rotation, the mounting plate 313 slides out of the mounting groove 312, and the sealing plate 314 moves away from the bottom of the discharge hole 311, causing the concrete cylinder discharge hole 311 to fall, thus realizing the inverted slump test. This allows the slump cylinder 2 to be quickly switched between upright and inverted test modes. If it is necessary to disassemble the slump cylinder 2 to conduct a slump test on the concrete, simply reverse the above steps to disassemble the slump cylinder 2, which also facilitates the cleaning and maintenance of the equipment.

[0026] In summary, this utility model includes a support frame 1 and a slump cylinder 2 disposed on the inner wall of the support frame 1. A slump assembly 3 is disposed on the outer wall of the slump cylinder 2 for quick installation and disassembly of the slump cylinder 2, enabling it to adapt to different types of slump tests and allowing for rapid replacement or adjustment of the slump cylinder 2. Through the coordinated design of the guide plate 303 and the limiting hole 308, and the positioning strip 305 and the positioning groove 310, this utility model ensures the accuracy of the slump cylinder 2's placement on the support frame 1, avoiding test errors caused by positional deviations. It also ensures a tight fit between the bottom end of the placement plate 301 and the top end of the support frame 1. Furthermore, the ability to quickly switch between upright and inverted test modes by the slump cylinder 2 reduces pre-test preparation and operational steps during testing, improving testing efficiency. It avoids the influence of different instrument dimensional errors, surface roughness differences, and other factors on the test results, thus ensuring the consistency and comparability of slump and inverted slump data, facilitating a more accurate evaluation of the concrete mixture's performance.
