Description

Technical Field

[0001] This utility model relates to the field of concrete slump testing technology, specifically to a concrete slump testing device. Background Technology

[0002] Cement concrete, as an important building material in infrastructure construction, usually requires relevant performance tests before use. Only after passing the tests can it be applied to engineering projects. The slump test is an important method for measuring the workability of cement concrete mixtures. In related technologies, a slump cone is commonly used in the slump test. During use, concrete is poured into the slump cone in three stages. After each pour, the concrete is thoroughly tamped and compacted. Then, the slump cone is lifted vertically, and the height difference between the highest point of the concrete sample and the slump cone is measured with a steel ruler. This height difference is the slump value.

[0003] Traditional concrete slump tests require manual movement of the slump cone to detach it from the concrete. However, manual movement cannot guarantee the vertical movement of the slump cone, compromising test accuracy and potentially leading to unsatisfactory results, which ultimately affect the quality of roadbed pouring. Therefore, a concrete slump test device is proposed. Utility Model Content

Example

[0025] Please see Figure 1-5 This utility model provides a technical solution: a concrete slump test device, including a base 1, a slump cylinder 2 placed at one top end of the base 1, a handle 3 provided on the outside of the slump cylinder 2; and a moving component, which is located at the other end of the slump cylinder 2.

[0026] By setting a moving component, the slump cylinder 2 can move vertically upward, ensuring the accuracy of the test. The moving component includes two guide pillars 4, two slide blocks 5, and a connecting shaft 6. The two guide pillars 4 are fixedly connected to the left side of the slump cylinder 2, and the two slide blocks 5 are slidably connected to the outside of the two guide pillars 4. Limit blocks are fixedly connected to the top of the two guide pillars 4 to limit the slide blocks 5. The connecting shaft 6 is fixedly connected between the two slide blocks 5. Two L-shaped brackets 7 are rotatably connected to the outside of the connecting shaft 6. A fixing frame 10 is hinged to one end of the two L-shaped brackets 7. A support column 8 is installed on the top of the base 1. A fixing shaft 9 is fixedly connected to the top of the support column 8. The fixing frame 10 is rotatably connected to both ends of the fixing shaft 9. A support component is set on the outside of the two slide blocks 5. By pressing the fixing frame 10 downward, one end of the fixing frame 10 moves upward. The one end of the fixing frame 10 pushes the L-shaped brackets 7 upward and drives the two slide blocks 5 to move outside the guide pillars 4 through the connecting shaft 6, thereby driving the support component to move vertically upward.

[0027] The support assembly includes two support plates 11, which are fixedly connected to the outside of two slide blocks 5. The top of the two slide blocks 5 is provided with a placement groove 12 and a limit component. The handle 3 is matched with the placement groove 12 and placed inside the placement groove 12. The L-shaped bracket 7 is pushed upward by one end of the fixing frame 10 and the two slide blocks 5 are moved outside the guide column 4 by the connecting shaft 6. Thus, the slump cylinder 2 is moved upward by the support plates 11, so that the slump cylinder 2 can move vertically upward. When the concrete leaves the inside of the slump cylinder 2, the concrete slump test can be completed.

[0028] By setting a limiting component, the collapse cylinder 2 can be fixed and prevented from shaking. The limiting component includes two fixing blocks 13, two limiting posts 14, and a tension spring 15. The two fixing blocks 13 are fixedly connected to the tops of the two support plates 11, and the two limiting posts 14 are movably inserted through the interior of the two fixing blocks 13. A tension spring 15 is fixedly connected between the fixing blocks 13 and the limiting posts 14. One end of each limiting post 14 is provided with an inclined surface 16. 14 are located above the handle 3 respectively; by placing the collapse cylinder 2 above the two support plates 11, and pressing the handle 3 against the inclined surface 16 of the limiting post 14, the collapse cylinder 2 is moved down, and the handle 3 pushes the limiting post 14 to move inside the fixing block 13. At this time, the tension spring 15 is stretched by force. When the handle 3 moves to the inside of the placement groove 12, the tension spring 15 drives the limiting post 14 to move inside the fixing block 13, so that the fixing block 13 moves above the handle 3, and the fixing of the handle 3 is completed.

[0029] The working principle or structural principle is as follows: When measuring the slump of concrete, the slump cylinder 2 is placed above the two support plates 11, and the handle 3 is pressed against the inclined surface 16 of the limiting post 14. Pressing down on the slump cylinder 2 moves the handle 3, pushing the limiting post 14 inside the fixing block 13. At this time, the tension spring 15 is stretched. When the handle 3 moves into the placement groove 12, the tension spring 15 drives the limiting post 14 to move inside the fixing block 13, causing the fixing block 13 to move above the handle 3, thus completing the fixing of the handle 3. The bottom of the slump cylinder 2 is pressed against the top of the base 1. Then, concrete is filled into the interior of the slump cylinder 2. The fixing frame 10 is then pressed down to move, causing one end of the fixing frame 10 to move upward. One end of the fixing frame 10 pushes the L-shaped bracket 7 upward and drives the two sliding blocks 5 to move outside the guide column 4 through the connecting shaft 6. This causes the slump cylinder 2 to move upward through the support plate 11, so that the slump cylinder 2 can move vertically upward to ensure the accuracy of the test. When the concrete leaves the interior of the slump cylinder 2, the concrete slump test is completed.
