Description

Technical Field

[0001] The invention relates to the technical field of concrete detection, and in particular to a concrete on-site construction state tester. Background Art

[0002] At the construction site, concrete is a common construction material. Different buildings have different requirements for the collapse of concrete. Different material moisture and external environment will affect the collapse of concrete. In many cases, it is necessary to test it on site.

[0003] The collapse of concrete refers to the plasticization and pumpability of concrete. The factors that affect the collapse of concrete include grading changes, water content, weighing deviation of scales, dosage of admixtures and temperature. The current method for detecting the collapse of concrete is: use a trumpet-shaped collapse barrel with an upper opening of 100mm, a lower opening of 200mm and a height of 300mm, and fill it with concrete in three times. After each filling, use a tamping hammer to evenly hit the outer wall of the collapse barrel 25 times. After tamping, smooth it and pull up the collapse barrel. The concrete collapses due to its own weight. The collapse can be obtained by subtracting the height of the concrete after collapse from the height of the barrel.

[0004] The above detection method requires the staff to use a hammer to directly knock the collapse bucket, which is time-consuming and labor-intensive, and the knocking is uneven, which makes the concrete in the collapse bucket vibrate unevenly, affecting the accuracy of the collapse detection result, and needs to be improved.

[0034] refer to Figure 1-Figure 8 The auxiliary feeding assembly includes a guide frame 35 installed above the detection platform 1, and a scraper ring 36 is fixedly installed at the lower end of the guide frame 35, and the inner diameter of the scraper ring 36 is adapted to the upper port of the detection tube 2. A bracket is fixedly installed on the detection platform 1, and a second electric push rod 34 is fixedly installed on the bracket. The output shaft of the second electric push rod 34 is fixedly connected to the guide frame 35, and a sealing gasket is provided on the bottom wall of the scraper ring 36.

[0035] When concrete collapse detection is required, the mounting frame 5 is first slid to a higher position. A through hole is provided on the first piston tube 19, and a plug is provided on the through hole. By removing the plug, the first piston rod 20 can slide freely, and the through hole needs to be plugged during detection.

[0036] The detection tube 2 is placed on the detection table 1, and the two first electric push rods 28 are used to drive the two clamping plates 29 to clamp and position the detection tube 2. It is worth noting that in order to increase the range of the knocking vibration, the size of the clamping plate 29 can be set larger, and the corresponding number of the knocking plates 33 and the third piston tube 31 can also be increased, which is not drawn in the figure.

[0037] After positioning is completed, the guide frame 35 and the scraper ring 36 are driven by the second electric push rod 34 to approach the detection cylinder 2 until the inner ring of the scraper ring 36 coincides with the upper port of the detection cylinder 2, and then the mounting frame 5 is driven to move downward, and the bulk rod 6 and multiple bulk frames 13 enter the detection cylinder 2 from the upper port of the detection cylinder 2, and then the through hole is blocked, and the concrete to be tested is poured into the detection cylinder 2 through the guide frame 35. After a certain height of concrete exists in the detection cylinder 2 (the height is about 50 mm, which is convenient for bulking), the motor 18 is started to compact the concrete to remove the bubbles inside.

[0038] Among them, an elastic rod is connected to the output shaft of the motor 18, and the bulk material rod 6 is fixedly connected to the elastic rod, that is, the bulk material rod 6 can slide up and down relative to the motor 18, and the motor 18 can drive the bulk material rod 6 to rotate, and the wedge block 16 is rotationally connected to the elastic rod, that is, it is also rotationally connected relative to the bulk material rod 6, that is, the wedge block 16 can slide up and down synchronously with the bulk material rod 6, and the mounting ring 10 is fixedly connected to the rotating plate 7, and the rotating plate 7 is slidingly connected to the slide rod 8. Through the slide rod 8, the rotating plate 7 and the mounting ring 10 can always maintain the same distance from the mounting frame 5, and the rotating plate 7 and the bulk material rod 6 are slidingly connected, that is, the rotating plate 7 can slide up and down relative to the bulk material rod 6, and the two rotate synchronously, and there is a certain distance between the rotating plate 7 and the wedge block 16, which can be appropriately adjusted according to actual needs.

[0039] Under the above conditions, the motor 18 drives the cam 24 to rotate during the process of driving the bulk material rod 6 to rotate. Figure 3 , Figure 5 and Figure 6 As shown, the cam 24 intermittently squeezes the wedge block 16 during the rotation process, causing it to move downward, thereby driving the bulk material bar 6 to move downward, and during the process of the bulk material bar 6 moving downward, multiple second bulk material plates 15 will flip upward until they are in a horizontal state, which can start the compaction effect, thereby improving the detection accuracy. When the squeezing is finished, the bulk material bar 6 moves upward and resets, and multiple second bulk material plates 15 flip downward, which can play a guiding role, preventing air from entering the concrete, and at the same time, allowing the concrete to flow directly below the second bulk material plates 15, facilitating the next compaction. At the same time, when the bulk material bar 6 moves downward, the transmission ring 12 moves downward to drive the gear 11 to rotate, thereby driving the bulk material rack 13 to swing, swinging toward the edge of the detection tube 2, and during the swinging process, the first bulk material plate 14 moves toward the detection tube 2, moving the concrete accumulated at the center to the edge of the detection tube 2, which can further reduce the bubbles in the concrete in the detection tube 2. On the contrary, when the bulk material rod 6 moves upward, the transmission ring 12 moves downward to drive the gear 11 to rotate in the opposite direction, thereby driving the bulk material rack 13 to swing in the opposite direction, and swing away from the edge of the detection tube 2. During the swinging process, the first bulk material plate 14 will rotate, so that the angle between the two first bulk material plates 14 becomes smaller, thereby preventing the concrete at the edge from being pushed back to the center.

[0040] During the rotation of the cam 24, the transmission plate 23 is pushed and pulled back and forth, and the transmission plate 23 drives the second piston rod 22 to slide back and forth in the second piston tube 21. When the second piston rod 22 slides into the second piston tube 21, the air in the second piston tube 21 enters the first piston tube 19, and the first piston rod 20 moves up under the action of air pressure. A one-way valve is provided on the first connecting tube 25. Every time the cam 24 rotates, air is added to the first piston tube 19 through the second piston tube 21, so that the first piston rod 20 moves up, and cooperates with the continuously raised concrete, thereby increasing the height of the bulk rack 13 and the bulk rod 6 until they leave the detection cylinder 2. When the second piston rod 22 moves to the outside of the second piston tube 21, external air is extracted. The second piston tube 21 is provided with an air inlet hole and a one-way valve.

[0041] When the second piston rod 22 moves into the second piston tube 21, the air at the other end of the second piston tube 21 will enter the multiple third piston tubes 31 through the second connecting tube. It is worth noting that the multiple third piston tubes 31 are connected. When the air enters the third piston tube 31, the third piston rod 32 moves to the outside of the third piston tube 31 and hits the clamping plate 29 with the knocking plate 33. When the second piston rod 22 moves to the outside of the second piston tube 21, the second piston tube 21 extracts the air in the third piston tube 31, thereby pulling the knocking plate 33 away from the clamping plate 29 and using vibration to accelerate the compaction of concrete. Further improve the efficiency and quality of detection.

[0042] After the concrete is full, the feeding is stopped, the bulk rod 6 and the bulk rack 13 are both separated from the detection cylinder 2, and the scraper ring 36 is driven by the second electric push rod 34 to scrape away the overflowed concrete. Finally, the detection cylinder 2 is removed to measure the collapse degree, and a laser measuring instrument can be set on the fixed ring 26 to further improve the detection accuracy.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
