Description

Technical Field

[0001] The invention belongs to the technical field of concrete detection, and in particular relates to a concrete slump detection device. Background Art

[0002] Concrete slump test is a common method for evaluating concrete workability, and currently relies mainly on manual operation. However, due to differences in operator experience, skill level, and operational norms, the accuracy and reliability of the test results are often affected. In addition, the assessment of concrete quality should not rely solely on slump testing, but also require a comprehensive analysis in combination with other key indicators (such as aggregate quality). Judging concrete quality based solely on slump results can easily lead to misjudgment and cannot fully reflect the actual performance of concrete.

[0003] In actual production, concrete is mainly composed of cement, water, sand and gravel, among which aggregates (sand and gravel) play a key skeleton role in concrete and directly affect the strength and durability of concrete. However, the existing slump test technology cannot effectively evaluate the key parameters of aggregates, such as gradation and shape. The influence of these parameters on the performance of concrete is crucial, especially when using secondary recycled aggregates. The fluctuation of aggregate quality may have a significant impact on the overall performance of concrete. If only focusing on the slump results and ignoring the potential impact of aggregates on the workability of concrete, it may lead to deviations in test results and even mislead production decisions.

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0034] like Figure 1 to Figure 3 As shown, a concrete slump detection device in one embodiment of the present invention comprises a shell 1, and a first cover 2 is rotatably connected to the shell 1. A slump test chamber 3 and an aggregate detection chamber 4 are arranged in the shell 1, and the slump test chamber 3 and the aggregate detection chamber 4 are independent. A slump detection mechanism 7 is installed in the slump test chamber 3, and an aggregate detection mechanism 22 is arranged in the aggregate detection chamber 4. The slump detection mechanism 7 is used to perform concrete slump detection. The aggregate detection mechanism 22 performs a secondary experiment by using the concrete after the slump detection of the recycled concrete, and realizes the screening of aggregates by washing and screening. The quality of the concrete is comprehensively judged by analyzing the gradation, shape, quality and other parameters of the aggregate, so as to avoid that the concrete meets the slump requirement because too many additives are added to the concrete, and it is not the strength of the concrete itself.

[0035] like Figure 1 to Figure 6 As shown, the slump detection mechanism 7 includes a first slide 14, which is fixedly connected to the side wall of the slump test chamber 3, and a second slide groove 1401 is opened on the first slide 14. A second slider 15 matching the second slide groove 1401 is slidably connected to the first slide 14, and a slump cone 16 is fixedly connected to one end of the second slider 15 away from the first slide 14.

[0036] The first slideway 14 is also slidably connected with a third slider 17 matching the second slideway 1401, and the end of the third slider 17 away from the first slideway 14 is fixedly connected with a first nozzle 18, and the first nozzle 18 is fixedly connected with a first connecting pipe 19, and the end of the first connecting pipe 19 away from the first nozzle 18 is connected with a concrete source. Generally, the end of the first connecting pipe 19 away from the first nozzle 18 is inserted into the concrete tank, and during the insertion process, it should be ensured that the concrete entering through the first connecting pipe 19 has a certain representativeness. The first nozzle 18 delivers concrete to the slump cone 16.

[0037] like Figure 1 to Figure 6 As shown, the slump detection mechanism 7 also includes a first telescopic rod 8, which is fixedly connected to the housing 1, and the output end of the first telescopic rod 8 is fixedly connected to a rotating platform 9, and the end of the rotating platform 9 away from the first connecting rod 10 is fixedly connected to a tamping rod. During the rotation of the rotating platform 9, the direction of the tamping rod can be changed so that the tamping rod can be spirally tamped into the concrete in the slump cone 16 from the outer box. Since concrete is generally filled in three layers, the height of each layer is about 1 / 3 of the height of the cone (about 100mm), therefore, the height of the tamping rod can be changed by the first telescopic rod 8, so that the tamping rod can penetrate the entire layer thickness and avoid hitting the bottom plate. By cooperating with the tamping rod, the rotating platform 9 and the first telescopic rod 8, the concrete can be guaranteed to be dense, and the error of the test result compared to manual tamping of concrete is smaller.

[0038] Specifically, Figure 5As shown, the upper end of the first slide 14 is fixedly connected with a first motor 21, and the output shaft of the first motor 21 is fixedly connected with a threaded rod 20 matching the third slider 17 and the second slider 15. The threaded rod 20 penetrates the third slider 17 and the second slider 15, and the threaded rod 20 is threadedly connected with the third slider 17 and the second slider 15. When the first motor 21 is started, the first motor 21 rotates with the threaded rod 20, and the threaded rod 20 can make the third slider 17 and the second slider 15 slide up or down at the same time during the rotation process. After the concrete is compacted by the tamping rod, the slump cone 16 is away from the concrete, and the slump cone 16 is lifted vertically and slowly to avoid shaking or tilting. The time for the slump cone 16 to completely leave the concrete is controlled to be completed within 5 to 10 seconds. After the slump cone 16 is away from the concrete, the concrete will collapse due to its own weight. After it is stable, the measuring ruler is placed vertically on the top of the slump cone to measure the height difference between the center point of the top of the concrete and the top of the slump cone. The height difference is the slump value.

[0039] After the slump test is completed, the inner wall of the slump test chamber 3 and the inner wall of the control chamber 6 need to be cleaned. In order to achieve automatic cleaning, Figure 6 to Figure 9 As shown, the tamping rod includes a first connecting rod 10 and a second connecting rod 11, and the second connecting rod 11 is sleeved on the outer wall of the first connecting rod 10. The first connecting rod 10 is provided with a first slide groove 1002, and the second connecting rod 11 is fixedly connected with a first slider 1102 matching the first slide groove 1002, and the first connecting rod 10 and the second connecting rod 11 are slidably connected through the cooperation of the first slide groove 1002 and the first slider 1102.

[0040] Specifically, Figure 6 to Figure 9 As shown, a delivery channel 1003 is provided inside the first connecting rod 10, a first through hole 1001 matching the delivery channel 1003 is provided on the first connecting rod 10, and a second through hole 1101 matching the first through hole 1001 is provided on the second connecting rod 11. The first through hole 1001 and the second through hole 1101 are arranged in a staggered manner in the initial state, that is, the first through hole 1001 and the second through hole 1101 are not connected to each other. An air delivery pipe 12 and a liquid delivery pipe 13 are installed on the first connecting rod 10, wherein the air delivery pipe 12 delivers gas into the slump test chamber 3, the liquid delivery pipe 13 is used to deliver water into the slump test chamber 3 to achieve the cleaning of the slump test chamber 3 and the control chamber 6, and the gas delivered by the air delivery pipe 12 is used to dry the slump test chamber 3 and the control chamber 6.

[0041] Furthermore, a slump cone 16 is installed at the lower end of the first connecting rod 10, and the slump cone 16 is located between the first connecting rod 10 and the second connecting rod 11, and the slump cone 16 is connected to the conveying channel 1003. When gas or liquid is conveyed in the conveying channel 1003, the gas and liquid first enter the slump cone 16, and the slump cone 16 expands, driving the second connecting rod 11 to slide on the first connecting rod 10 to achieve the alignment of the second through hole 1101 and the first through hole 1001. After the first through hole 1001 and the second through hole 1101 are aligned, the water or gas in the conveying channel 1003 will be sprayed out from the second through hole 1101. The water or gas will be sprayed on the inner wall of the control chamber 6 to clean or dry the inner wall of the control chamber 6. The water or gas flows along the inner wall of the control chamber 6 to flow to the inside of the slump test chamber 3 to clean and dry the inside of the slump test chamber 3.

[0042] like Figure 8 As shown, a second slider 15 is installed between the first chute 1002 and the first slider 1102. When the liquid delivery pipe 13 and the gas delivery pipe 12 stop delivering, the tension generated by the second slider 15 causes the slump cone 16 to deform, and the gas or water in the slump cone 16 is squeezed and delivered to the delivery channel 1003. At this time, the first chute 1002 and the first slider 1102 are misaligned. In this state, the second connecting rod 11 acts as a tamping rod. This arrangement can prevent water and impurities in the concrete from entering the delivery channel 1003 and causing the delivery channel 1003 to be blocked.

[0043] like Figures 1 to 9 As shown, a feeding assembly 28 is installed between the slump test chamber 3 and the aggregate detection chamber 4. Before cleaning, the feeding assembly 28 transports the concrete in the slump test chamber 3 to the aggregate detection mechanism 22. After most of the concrete in the slump test chamber 3 enters the aggregate detection mechanism 22, the first motor 21 is started to make the slump cone 16 located in the middle of the aggregate detection mechanism 22, and the air pipe 12 outputs water, and the water impacts the inner wall of the slump cone 16 to achieve the cleaning of the slump cone 16. The impact force generated by the water impact can also simply rinse the inner wall of the slump test chamber 3. After the inner wall of the slump cone 16 is cleaned, it can be discharged through a drainage device (not shown in the figure).

[0044] After the water is drained, the gas supply pipe 12 stops outputting, and the gas is output to the slump test chamber 3 through the liquid supply pipe 13. Similarly, the first connecting rod 10 is located inside the slump cone 16, and the blown gas can dry the control chamber 6 and the slump test chamber 3, and make the inner wall of the slump cone 16 and the bottom wall of the slump test chamber 3 in a moist state, so that the next slump test can be carried out.

[0045] It is worth noting that during the cleaning process, it should be ensured that the inner wall of the slump cone 16 and the bottom wall of the slump test chamber 3 do not have too many impurities that affect the slump test.

[0046] Preferably, in order to reduce the influence of the residual concrete in the first connecting pipe 19 on the result of the slump test, a third nozzle (not shown in the figure) can be installed on the first connecting pipe 19. The third nozzle is located outside the shell 1. The third nozzle is used to discharge the residual concrete in the first connecting pipe 19. After the new concrete enters the first connecting pipe 19, the new concrete is transported to the slump cone 16 through the first nozzle 18.

[0047] like Figures 1 to 10 As shown, the material delivery assembly 28 includes a material pump 29, the inlet end of the material pump 29 is fixedly connected to a second connecting pipe 30, one end of the second connecting pipe 30 away from the material pump 29 is fixedly connected to the side wall of the slump test chamber 3, and communicates with the slump test chamber 3. The output end of the material pump 29 is fixedly connected to a third connecting pipe 31, and one end of the third connecting pipe 31 away from the material pump 29 is installed on the aggregate detection mechanism 22, so as to transport concrete materials into the aggregate detection mechanism 22.

[0048] like Figures 1 to 10 As shown, the aggregate detection mechanism 22 includes a second motor 23, which is fixedly connected to the upper end of the housing 1, and the output end of the second motor 23 is fixedly connected to a third connecting rod 27 that matches the aggregate detection chamber 4, and the third connecting rod 27 is sequentially provided with a second inner cylinder 26 and a first inner cylinder 25 from the inside to the outside. That is, the second inner cylinder 26 and the first inner cylinder 25 are both fixedly connected to the third connecting rod 27, and the second inner cylinder 26 is located inside the first inner cylinder 25. A plurality of second filter holes 2601 are provided on the second inner cylinder 26, and a plurality of first filter holes 2501 are provided on the first inner cylinder 25. A sealing barrel 24 is also fixedly connected to the inner wall of the aggregate detection chamber 4.

[0049] like Fig.10As shown, the end of the third connecting pipe 31 away from the material pump 29 is fixedly connected with a rotary joint 32, and the rotary joint 32 is installed on the third connecting rod 27, and a feeding channel 2701 is opened in the third connecting rod 27, and a discharge port 2702 matching the feeding channel 2701 is opened on the third connecting rod 27. Concrete is transported from the third connecting pipe 31 to the feeding channel 2701 in the third connecting rod 27 through the rotary joint 32, and finally discharged from the discharge port 2702 to the inside of the second inner cylinder 26. When the concrete is completely located in the second inner cylinder 26, the second motor 23 is started, and the third connecting rod 27 is driven by the second motor 23 to rotate. During the rotation process, the third connecting rod 27 drives the second inner cylinder 26 and the first inner cylinder 25 to rotate. Small particles of aggregate enter the first inner cylinder 25 through the second filter hole 2601, and impurities and water enter the sealing barrel 24 through the first filter hole 2501. In this way, the material classification can be achieved, and by observing the classification and appearance of the materials in the second inner cylinder 26 and the first inner cylinder 25, it can be determined whether the aggregate used is secondary recycled material.

[0050] like Figure 2 As shown, a clean water pipe 43 is also installed on the third connecting pipe 31. When the second motor 23 drives the third connecting rod 27 to rotate, the clean water pipe 43 transports water into the third connecting pipe 31, and the water is finally discharged through the discharge port 2702. The water is located in the second inner cylinder 26, and the aggregates in the second inner cylinder 26 and the first inner cylinder 25 are cleaned.

[0051] In order to further check the quality of the aggregate, a plurality of first grinding balls are placed in the second inner cylinder 26, and a plurality of second grinding balls are placed in the first inner cylinder 25. During the rotation of the second inner cylinder 26 and the first inner cylinder 25, the first and second grinding balls rotate with the second inner cylinder 26 and the first inner cylinder 25, and come into contact with the aggregate in the second inner cylinder 26 and the first inner cylinder 25 to grind the aggregate. Within a certain period of time, the remaining amount of the aggregate is checked, and the strength of the aggregate is judged according to the remaining amount.

[0052] like Fig.10 As shown, a sewage pipe 40 is fixedly connected to the lower end of the sealing barrel 24 , and sewage in the sealing barrel 24 can be discharged through the sewage pipe 40 .

[0053] Preferably, the second inner cylinder 26 and the first inner cylinder 25 are also provided with a first discharge mechanism (not shown in the figure), and the first discharge mechanism is used to discharge the aggregate in the second inner cylinder 26 and the first inner cylinder 25. Specifically, it can be configured as follows: the aggregate is transported to the sealed barrel 24 by long-term grinding by the first and second grinding balls, and the aggregate is discharged through the sewage pipe 40. Of course, it is also possible to open a discharge port on the sealed barrel 24, the first inner cylinder 25, and the second inner cylinder 26, and discharge the material manually, as long as the material in the first inner cylinder 25 and the second inner cylinder 26 is discharged.

[0054] The housing 1 is provided with a visual inspection component (not shown in the figure), which includes several cameras matching the first cover 2, the slump test chamber 3, and the aggregate detection chamber 4. The camera is used to shoot and upload the captured content. After uploading, the slump test results and the aggregate quality test results are saved, and the data uploaded by the visual inspection component can be queried. In addition, during the detection process, a video can also be shot, which can be transmitted by wire or wireless means and displayed in real time.

[0055] like Figure 1 to Figure 4 As shown, the housing 1 is also provided with a corrosion-resistant detection chamber 5 and a control chamber 6. A discharge mechanism 33 is installed in the corrosion-resistant detection chamber 5, and the corrosion test of concrete can be performed through the discharge mechanism 33. A control device is installed in the control chamber 6 to control the concrete slump detection device.

[0056] Specifically, Figure 11-12 As shown, the discharge mechanism 33 includes a second slide 35, the second slide 35 is fixedly connected to the side wall of the corrosion-resistant detection chamber 5, a fourth slider 36 is slidably connected to the second slide 35, a fifth slider 37 is slidably connected to the fourth slider 36, and the sliding direction of the fourth slider 36 and the sliding direction of the fifth slider 37 are perpendicular to each other. A second nozzle 38 is fixedly connected to the fifth slider 37, and a fifth connecting pipe 39 matching the second nozzle 38 is fixedly connected to the first nozzle 18, and concrete is transported to the second nozzle 38 through the fifth connecting pipe 39, and then the concrete is discharged by the second nozzle 38.

[0057] A storage box 41 is installed at the bottom of the corrosion-resistant test chamber 5. The storage box 41 is provided with a plurality of storage bins 42. The second nozzle 38 sprays concrete into the storage bins 42. A heating component matching the storage bins 42 is installed on the storage box 41. The storage bins 42 can be heated separately by the heating component. This simulates the state of concrete at different temperatures to see whether cracks will occur. In the process, the test is recorded by the visual inspection component.

[0058] like Fig.11 As shown, a corrosive liquid delivery pipe 34 is installed on the fifth connecting pipe 39, and the corrosive liquid delivery pipe 34 delivers corrosive liquid into the fifth connecting pipe 39. When the concrete is formed, the corrosive liquid is sprayed on the concrete in the storage bin 42 to test the corrosion resistance of the concrete.

[0059] When in use, first insert the end of the first connecting pipe 19 away from the first nozzle 18 into the concrete, and the concrete is sprayed into the slump cone 16 through the first connecting pipe 19 and the first nozzle 18. The height of the concrete output by the first nozzle 18 is 1 / 3 of the height of the slump cone 16. The first telescopic rod 8 is driven to move downward with the rotating platform 9 and the tamping rod, and the concrete in the slump cone 16 is compacted by the tamping rod. This process is performed three times. In the last time, the upper surface of the concrete is flush with the upper surface of the slump cone 16, and the concrete on the upper surface of the high slump cone 16 should be cleaned. The slump cone 16 is moved upward by the second slider 15, so that the slump cone 16 completely falls off the concrete, and the concrete collapses automatically. After the collapse, the result is recorded by the visual detection component.

[0060] If the slump test result is qualified, the concrete in the slump test chamber 3 is transported to the aggregate detection mechanism 22 through the feeding assembly 28. The aggregate detection mechanism 22 screens the concrete, grades the aggregate, and performs quality inspection on the aggregate by grinding. The ratio of aggregate, water and lime is calculated according to the remaining amount of aggregate, so as to comprehensively realize the inspection of concrete quality.

[0061] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
