Description

Technical Field

[0001] The present application relates to the technical field of concrete testing equipment, and in particular to a concrete slump detection device and method. Background Art

[0002] Concrete slump is a key indicator for assessing concrete fluidity and plays a crucial role in construction projects. Accurately measuring concrete slump can effectively determine whether construction conditions meet requirements, thereby ensuring project quality and efficiency. Traditional methods for measuring concrete slump rely primarily on manual labor and simple tools. While these methods are mature and reliable, they still face numerous challenges in the increasingly complex landscape of modern construction, particularly with the increasing demands for efficiency and cleanliness.

[0003] The existing Chinese patent, with publication number CN213091677U, includes a slump bucket, a scale, and a mounting base. Both the bucket and the scale are removably fixed to the mounting base, with the centerlines of the bucket and the scale perpendicular to the mounting base. During testing, the bucket is placed on the mounting base. Concrete is then poured into the bucket, vibrated, and leveled. The bucket is then lifted and measured.

[0004] The above-mentioned related technologies have the following defects: after the test is completed, both the slump bucket and the mounting surface of the concrete sample need to be cleaned. Especially in the laboratory scenario, the process of transporting and cleaning each component is relatively inconvenient, so it needs to be improved. Summary of the Invention

[0006] A concrete slump detection device includes a detection frame, the detection frame is rotatably provided with a support plate, the top surface of the support plate is a support surface and is used to place a slump bucket, the bottom surface of the support plate is a cleaning surface, the detection frame is provided with a recovery box at the bottom of the support plate, the detection frame is provided with a lifting mechanism for driving the slump bucket to move up and down, the detection frame is provided with a flip drive for driving the support plate to rotate, and a cleaning channel is provided inside the support plate; The cleaning channel is connected to a support hole, the end of the support hole extends to the support surface, a support block and a sealing plate are provided inside the support hole, the support block is in clearance with the support hole and seals the cleaning channel, an elastic member is provided between the support block and the cleaning channel, and the sealing plate is adapted to the support hole and flush with the support surface; The cleaning channel is connected to a cleaning hole, and an end of the cleaning hole extends to the cleaning surface.

[0007] By adopting the above technical solution, the automatic cleaning function of the concrete slump detection device is realized.

[0008] The detection process is: In the initial state, the flip drive drives the support plate to rotate to a horizontal state, and keeps the support surface set upward, and then the lifting mechanism drives the slump bucket down to contact the support surface; Pour the concrete sample to be tested into the slump bucket and vibrate it. Finally, smooth the concrete sample to be tested on the top of the slump bucket until it is flush with the top wall of the slump bucket. By using the lifting mechanism to drive the slump bucket to rise, the natural slump of the concrete sample to be tested can be achieved, and then the height can be measured.

[0009] After the measurement, start the cleaning process: The support plate is rotated 180 degrees by the flip drive so that the cleaning surface is set upwards. Then the slump bucket is driven down by the lifting mechanism until it contacts the cleaning surface. In this state, the cleaning channel is supplied with liquid, and then the cleaning hole sprays the cleaning liquid to flush the slump bucket. The support block and the sealing plate as a whole overcome the downward movement of the elastic part, the support block no longer blocks the cleaning hole, and the sealing plate no longer blocks the support hole, so that the cleaning liquid in the cleaning channel flows into the support hole and finally flushes the support surface under the rebound action of the sealing plate.

[0010] The specific effects are as follows: 1. The design of the support plate allows for flexible switching between the detection surface and the cleaning surface, reducing the workload of manual handling and cleaning and improving operational convenience.

[0011] 2. The coordinated design of the cleaning channel, support holes and cleaning holes enables comprehensive flushing of the slump bucket and support surface after the test is completed, effectively removing residual concrete and ensuring the cleanliness of the equipment.

[0012] 3. The linkage mechanism between the support block and the sealing plate automatically opens during the cleaning process to ensure that the cleaning fluid flows accurately to the target area.

[0013] 4. The setting of the recycling box can centrally collect the fallen concrete samples and the waste liquid after cleaning, reducing environmental pollution and facilitating subsequent processing.

[0014] Preferably, a sealing ring is provided on the edge of the sealing plate, the sealing ring is located inside the supporting hole, and a guide surface is provided on the inner edge of the sealing ring.

[0015] By adopting the above technical solution, a sealing ring is provided on the edge of the sealing plate and a guide surface is provided on the inner edge of the sealing ring, so that after the sealing plate extends out of the supporting hole, when the cleaning liquid flows downward from the gap between the supporting block and the supporting hole, the water flow will be turned back when it hits the guide surface, and then it will be tilted along the direction of the guide surface to flush toward the supporting surface, thereby improving the flushing effect on the supporting surface.

[0016] Preferably, a mounting ring is fixedly provided on the inner side of the sealing ring, and the mounting ring is threadedly connected to the outer edge of the support plate.

[0017] By adopting the above technical solution, the design of the threaded connection between the mounting ring and the outer edge of the support plate facilitates the rapid disassembly and replacement of the sealing ring, thereby ensuring that the sealing ring can be easily maintained or updated after long-term use, thereby ensuring the reliability and durability of the device.

[0018] Preferably, an adjustment ring is provided at one end of the elastic member away from the support block, and the adjustment ring is threadedly connected to the cleaning channel.

[0019] By adopting this technical solution, the tightness of the elastic member can be adjusted. Specifically, by rotating the adjustment ring, the elastic member's compression or tension can be changed, thereby adjusting the maximum extent to which the sealing plate can extend out of the support hole under the same water pressure conditions. This design not only improves the controllability of the water flow intensity of the support surface, but also provides flexibility to meet different cleaning needs, effectively improving cleaning efficiency and cleaning results.

[0020] Preferably, a spray cover is rotatably provided inside the cleaning hole, an inclined spray hole is provided through the spray cover, and a rotating fan blade is fixedly provided on the spray cover.

[0021] By adopting the above technical solution, a rotating spray cover is arranged inside the cleaning hole. The inclined spray hole on the spray cover can form an inclined water column when the cleaning liquid flows out. At the same time, the rotating fan blades are impacted by the water flow and drive the spray cover to rotate, so that the inclined water column continuously changes direction, thereby expanding the cleaning range and improving the flushing effect of the slump bucket.

[0022] Preferably, a vibrating rod and a vibrating drive for driving the vibrating rod to reciprocate are provided on the top of the detection frame.

[0023] By adopting the above technical solution, an automated vibration function is realized. The vibrating rod can reciprocate under the action of the vibrating drive, thereby effectively vibrating the concrete in the slump bucket, reducing the labor intensity of manual operation and improving detection efficiency and accuracy.

[0024] Preferably, a mounting plate is provided on the top of the detection frame, a ball socket is provided inside the mounting plate, a ball head is rotatably provided inside the ball socket, and the vibrating rod and the vibrating drive are both connected to the ball head.

[0025] By adopting the above technical solution, the connection between the vibrating rod and the vibrating drive and the ball head is realized, and the ball head can rotate freely in the ball socket, thereby facilitating the adjustment of the actual vibration direction and position of the vibrating rod, improving operational flexibility, and meeting the vibration requirements under different working conditions.

[0026] Preferably, a mounting cavity is provided on the side of the ball socket, an abutment wheel is rotatably provided in the mounting cavity, the abutment wheel abuts against the ball head, and the ball head is provided with an abutment drive for driving the abutment wheel to rotate.

[0027] By adopting this technical solution, the angle and position of the vibrator can be automatically adjusted. The specific effect is as follows: By applying a controllable deflection force to the ball head and leveraging the interaction between the abutment wheel and the ball head, the vibrator's working posture can be precisely adjusted, improving operational flexibility. By controlling the rotation of the abutment wheel with the abutment drive, the ability to control the ball head's trajectory is further enhanced, ensuring that the vibrator can adapt to the needs of different working conditions.

[0028] Preferably, an abutting annular groove is sleeved on the outer side of the top of the slump bucket, and the top wall of the abutting annular groove is flush with the top wall of the slump bucket.

[0029] By adopting this technical solution, during the concrete slump test, the abutment ring groove can effectively receive overflow concrete from pouring or leveling, preventing it from adhering to the outer wall of the slump bucket or dripping onto the supporting surface, thereby avoiding interference with subsequent slump test results. Specifically, when excessive concrete is poured into the slump bucket using a funnel and then removed after vibration and leveling, the excess concrete is collected by the abutment ring groove, ensuring a clean testing environment and positively impacting test accuracy.

[0030] A detection method based on a concrete slump detection device, The detection process is: In the initial state, the flip drive drives the support plate to rotate to a horizontal state, and keeps the support surface set upward, and then the lifting mechanism drives the slump bucket down to contact the support surface; Pour the concrete sample to be tested into the slump bucket and vibrate it. Finally, smooth the concrete sample to be tested on the top of the slump bucket until it is flush with the top wall of the slump bucket. The slump bucket is driven upward by the lifting mechanism to realize the natural slump of the concrete sample to be tested, and then the height is measured; After the measurement, start the cleaning process: The support plate is rotated 180 degrees by the flip drive so that the cleaning surface is set upwards. Then the slump bucket is driven down by the lifting mechanism until it contacts the cleaning surface. In this state, the cleaning channel is supplied with liquid, and then the cleaning hole sprays the cleaning liquid to flush the slump bucket. The support block and the sealing plate as a whole overcome the downward movement of the elastic part, the support block no longer blocks the cleaning hole, and the sealing plate no longer blocks the support hole, so that the cleaning liquid in the cleaning channel flows into the support hole and finally flushes the support surface under the rebound action of the sealing plate.

[0031] By adopting the above technical solution, the automatic cleaning function of the concrete slump detection device is realized. The specific effects are as follows: 1. The double-sided design of the support plate (support surface and cleaning surface) combined with the flip drive can quickly switch to the cleaning mode after the inspection is completed, improving cleaning efficiency and reducing manual operations.

[0032] 2. The design of the cleaning channel, support holes and cleaning holes can effectively flush the support surface and cleaning surface respectively to ensure that residues are completely removed.

[0033] 3. The cooperation between the sealing plate and the supporting block closes the cleaning channel in the non-cleaning state to prevent the entry of external impurities such as concrete samples; in the cleaning state, the sealing plate is opened by water pressure, and the cleaning liquid flows out smoothly, enhancing the cleaning effect.

[0034] 4. The elastic part ensures the automatic reset function of the sealing plate, simplifies the structural complexity and improves the reliability of the equipment.

[0035] 5. The application of the lifting mechanism not only meets the height adjustment requirements of the slump bucket during the testing process, but also coordinates the positioning operation during the cleaning stage, optimizing the overall process.

[0036] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up the flip drive and cleaning channel, it can quickly switch to the cleaning mode after the inspection is completed, realizing the automatic cleaning of the slump bucket and the supporting surface, significantly reducing manual intervention and improving work efficiency; 2. The design of the support block and sealing plate inside the support hole in conjunction with the elastic parts enables the cleaning liquid to automatically open the flow path and flush the support surface, ensuring thorough cleaning while maintaining a compact structure; 3. The waste liquid after cleaning can be collected in a centralized manner through a recycling box to avoid environmental pollution and improve the cleanliness and environmental protection performance of the entire device.

[0039] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments are only possible technical implementations of the present invention and are not all possible implementations. Those skilled in the art can fully combine the embodiments of the present invention to derive other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0040] The inventors of this application discovered that parts need to be cleaned after concrete slump testing, and traditional cleaning methods are inconvenient. Therefore, this application mainly adopts a concrete slump detection device, including a detection frame, a rotatable support plate and related auxiliary structures, which achieves the effect of simplifying the cleaning operation. The following is a further detailed description of this application.

[0041] Example 1 Reference Figure 1The concrete slump detection device provided in the embodiment of the present application includes a detection frame 1. A support plate 2 is provided in the middle of the detection frame 1 through a rotating shaft, and a flip drive 10 is installed on the side of the detection frame 1. The flip drive 10 is a motor for controlling the rotation of the support plate 2. The top surface of the support plate 2 is a support surface 21 and is used to place the slump bucket 11. The bottom surface of the support plate 2 is a cleaning surface 22. After the detection is completed, the support surface 21 can be flipped by the flip drive 10, and then the slump bucket 11 can be flushed through the cleaning surface 22. A recovery box 12 is also placed below the support plate 2 of the detection frame 1. The recovery box 12 is used to receive waste liquid during the cleaning process and to receive fallen concrete samples. A lifting mechanism 13 is provided above the support plate 2 of the detection frame 1. The lifting mechanism 13 uses a motor in conjunction with a screw sleeve to realize the lifting and lowering of the slump bucket 11. The detection frame 1 is located above the slump bucket 11 and is also provided with a vibrating mechanism 3, and the vibrating mechanism 3 is also connected to the lifting mechanism 13. The lifting mechanism 13 is equipped with two pairs of sliding sleeves on the screw rod for installing the slump bucket 11 and the vibrating mechanism 3 respectively, so as to realize the synchronous lifting and lowering of the vibrating mechanism 3 and the slump bucket 11.

[0042] Reference Figure 2 A funnel 14 is inserted into the inner side of the top of the slump bucket 11. When pouring concrete, the funnel 14 needs to be used for drainage, and the funnel 14 needs to be removed eventually. However, after removing the funnel 14 and when scraping the concrete on the top of the slump bucket 11, concrete overflow will inevitably occur. Therefore, the outer side of the top of the slump bucket 11 of the present application is provided with an abutment ring groove 15, and the top wall of the abutment ring groove 15 is flush with the top wall of the slump bucket 11. When actually pouring concrete into the slump bucket 11, it is usually necessary to use the funnel 14. First, pour excess concrete into the funnel 14, then vibrate it, and then remove the funnel 14 and scrape the top wall of the slump bucket 11 with a scraper. Concrete overflow will occur during the process of removing the funnel 14 and scraping it. At this time, the abutment ring groove 15 can be used to receive it, so as to prevent the overflowed concrete from adhering to the outer wall of the slump bucket 11 or even falling to the support surface 21 of the support plate 2 and affecting the subsequent slump test results. This design can receive overflowing concrete during the pouring and leveling process, preventing contamination of the outer wall of the slump bucket 11 and even the support surface 21. The additional abutment ring groove 15 is added to intercept overflow, avoiding residue left behind that may cause subsequent measurement errors, and ensuring the accuracy of the test results.

[0043] Reference Figure 3The vibration mechanism 3 includes a vibrating rod 31 and a vibrating drive 32 for driving the vibrating rod 31 to reciprocate. A mounting plate 33 is provided on the top of the detection frame 1. A ball socket 34 is provided inside the mounting plate 33. A ball head 35 is provided inside the ball socket 34 for rotation. The vibrating rod 31 and the vibrating drive 32 are both connected to the ball head 35 to achieve convenient adjustment of the vibration direction and position. In addition, the mounting plate 33 is also provided with a mounting cavity located on the side of the ball socket 34. An abutment wheel 36 is provided inside the mounting cavity through rotation of a rotating shaft. The abutment wheel 36 abuts against the ball head 35, and an abutment drive 37 is provided on the mounting plate 33. The abutment drive 37 is a motor for driving the abutment wheel 36 to rotate, thereby achieving the overall rotation of the ball head 35 and the vibration mechanism 3. The introduction of an automated vibration system for the vibrating rod 31 effectively alleviates the burden of manpower while allowing flexible adjustment of the vibration angle and position, thereby improving the convenience and accuracy of operation.

[0044] Reference Figure 4 and Figure 5 A cleaning channel 20 is provided inside the support plate 2. The cleaning channel 20 itself can also be made of corrosion-resistant PVC pipes or metal alloy products as pipe materials, and the inner wall is smoothed to reduce resistance. The cleaning channel 20 has an extended channel toward the support surface 21 and the cleaning surface 22. The support hole 4 extends to the support surface 21. A support block 41 and a sealing plate 42 are provided inside the support hole 4. The support block 41 is clearance-matched with the support hole 4 and the support block 41 blocks the cleaning channel 20. The sealing plate 42 is larger than the support block 41, and the outer surface of the sealing plate 42 is flush with the support surface 21. The sealing plate 42 can be made of stainless steel sheet or plastic composite material and is connected and fixed to the support block 41 by gluing or other methods. The shape of the support hole can be customized into different cross-sectional styles such as circular and square according to actual needs. The wall thickness needs to be reasonably planned to meet the strength requirements while reducing weight. Specifically, a sealing ring 43 is provided on the edge of the sealing plate 42. The sealing ring 43 is located inside the support hole 4, and a guide surface 44 is provided on the inner edge of the sealing ring 43. When sealing plate 42 extends out of support hole 4, the cleaning fluid flows downward through the gap between support block 41 and support hole 4. The water flow hits guide surface 44, where it bends back and then flows along guide surface 44, slanting toward support surface 21 to improve the flushing effect. A mounting ring 45 is fixedly mounted on the inner side of sealing ring 43 and is threadedly connected to the outer edge of support plate 2, facilitating the removal, assembly, and replacement of sealing ring 43.

[0045] An elastic member 46 is provided between the support block 41 and the cleaning channel 20, for pulling the support block 41 toward the cleaning channel 20. The elastic member 46 can be a helical compression spring or other device with a restoring force function. The support block 41 can be made of high-strength steel or aluminum alloy in various forms such as a small block or a cylindrical shape. An adjustment ring 47 is provided at one end of the elastic member 46 away from the support block 41, and the adjustment ring 47 is threadedly connected to the cleaning channel 20. The tightness of the elastic member 46 is adjusted by rotating the adjustment ring 47, thereby achieving the maximum extent to which the sealing plate 42 can extend out of the support hole 4 under the same water pressure, thereby achieving control of the intensity of the water flow for flushing the support surface 21.

[0046] The cleaning channel 20 extends to the cleaning surface 22 through the cleaning hole 5. A spray cap 51 is rotatably mounted within the cleaning hole 5. This spray cap 51 extends through an inclined spray hole 52, and a rotating fan blade 53 is fixedly mounted within the spray cap 51. When cleaning fluid flows through this area, it drives the rotating fan blade 53 and the spray cap 51 to rotate as a whole. As the spray hole 52 rotates, a dynamic, tilted water jet is sprayed, expanding the flushing coverage area.

[0047] In summary, the implementation principles of this embodiment are: First of all, the concrete slump detection device mainly includes the following core components: Detection frame 1: main frame, internally integrated lifting mechanism 13, flip drive 10 and vibration system; Support plate 2: rotatably connected to the middle of the detection frame 1, the top surface is a support surface 21 for placing the slump bucket 11, and the bottom surface is a cleaning surface 22; Recovery box 12: fixed at the bottom of the detection frame 1, used to collect cleaning waste liquid; Lifting mechanism 13: includes a motor-driven screw slide assembly for controlling the vertical movement of the slump bucket 11; Flip drive 10: includes a servo motor and a gear transmission mechanism, drives the support plate 2 to flip around the axis from 0° to 180°; Cleaning channel 20: embedded in the support plate 2, connecting the support hole 4 and the cleaning hole 5, and equipped with an elastic reset component; Vibration system: includes a vibrating rod 31, a vibrating drive 32 and a multi-degree-of-freedom adjustment mechanism.

[0048] The detection process is: In the initial state, the turning drive 10 drives the support plate 2 to rotate to a horizontal state, and keeps the support surface 21 upwardly set, and then the lifting mechanism 13 drives the slump bucket 11 down to contact the support surface 21; Pour the concrete sample to be tested into the slump bucket 11 and vibrate it, and finally smooth the concrete sample to be tested on the top of the slump bucket 11 until it is flush with the top wall of the slump bucket 11; The slump bucket 11 is driven upward by the lifting mechanism 13 to achieve the natural collapse of the concrete sample to be tested, and then the height is measured; After the measurement, start the cleaning process: The support plate 2 is rotated 180 degrees by the flip drive 10 so that the cleaning surface 22 is positioned upward, and then the slump bucket 11 is lowered by the lifting mechanism 13 until it contacts the cleaning surface 22. In this state, the cleaning channel 20 is supplied with liquid, and then the cleaning hole 5 sprays the cleaning liquid to rinse the slump bucket 11. The support block 41 and the sealing plate 42 overcome the downward movement of the elastic member 46 as a whole, the support block 41 no longer blocks the cleaning hole 5, and the sealing plate 42 no longer blocks the support hole 4, so that the cleaning liquid in the cleaning channel 20 flows into the support hole 4 and finally flushes the support surface 21 under the rebound action of the sealing plate 42.

[0049] Reference Figures 6 to 8 , the embodiment of the present application also discloses a method for detecting the slump of concrete.

[0050] The following steps are involved: Initial positioning: The tilting drive 10 adjusts the support plate 2 to a horizontal position (with the support surface 21 facing upward), and the lifting mechanism 13 lowers the slump bucket 11 to the support surface 21; Sample processing: After filling with concrete, start the vibration system and smooth the top of the cylinder; Slump measurement: lift the slump bucket 11 and record the slump height of the concrete; Automatic cleaning: flip the support plate 2 so that the cleaning surface 22 faces upward, and the cleaning liquid is sprayed through the support hole 4 and the cleaning hole 5, and the waste liquid flows into the recovery box 12.

[0051] The implementation principle of a concrete slump detection device and method in the embodiment of the present application is as follows: Efficient cleaning: The double-sided support plate 2 is combined with the flip drive 10 to achieve rapid switching between detection and cleaning modes; the cleaning liquid dynamically covers the support surface 21 and the cylinder, and the residue removal rate is higher; Precise vibration: The vibrating rod can be adjusted at 31 degrees to ensure uniform density of concrete; Environmentally friendly design: recycling box 12 centrally processes waste liquid to reduce environmental pollution; Easy to operate: The entire process is automated, reducing manual intervention.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.

In this state, the cleaning channel (20) is supplied with liquid, and then the cleaning hole (5) sprays the cleaning liquid to wash the slump bucket (11); The support block (41) and the sealing plate (42) as a whole overcome the downward movement of the elastic member (46), the support block (41) no longer blocks the cleaning hole (5), and the sealing plate (42) no longer blocks the supporting hole (4), so that the cleaning liquid in the cleaning channel (20) flows into the supporting hole (4) and finally flushes the supporting surface (21) under the rebound action of the sealing plate (42).
