Description

Technical Field

[0001] The invention relates to the technical field of concrete detection, in particular to a concrete slump detection device and a detection method for municipal engineering construction. Background Art

[0002] The slump of concrete is an important indicator to measure its workability. It directly affects the performance of concrete during the construction process such as mixing, transportation, and pouring, as well as the quality of concrete after hardening. The detection of concrete slump mainly relies on manual operation, using simple tools such as standard slump cones. The specific operation is to load the concrete into the slump cone in three layers, tamp each layer with a tamping rod for a certain number of times, then scrape it flat, lift the slump cone vertically, and measure the height difference between the cone height and the highest point of the concrete specimen after collapse, which is the slump value.

[0003] According to the Chinese patent publication number CN118150814A, the patent provides a concrete slump detection device, including an L-shaped plate and a steel plate. Several moving wheels are arranged at the bottom end of the steel plate, a feeding pipe is arranged on the horizontal plate of the L-shaped plate, a tamping mechanism is arranged on one side of the horizontal rod of the L-shaped plate, and a height adjustment mechanism capable of lifting the slump bucket is arranged on the top surface of the steel plate. The moving wheel drives the slump bucket on the steel plate to move to the bottom of the feeding pipe. At this time, the height adjustment mechanism contacts the handle of the slump bucket and fixes the slump bucket. The material is poured into the slump bucket through the feeding pipe, and then the slump bucket is moved to the bottom of the tamping mechanism through the steel plate and the moving wheel. The slump bucket is tamped by the tamping mechanism. After the tamping is completed, the feeding operation is performed again. By analogy, after the three-layer tamping is completed, the moving wheel drives the steel plate and the slump bucket away from the L-shaped plate. At this time, the height adjustment mechanism lifts the slump bucket vertically, and the concrete collapses naturally. The subsequent measurement is performed by a ruler to complete the slump detection of the concrete.

[0004] However, concrete easily adheres to the inner wall of the test barrel, making it difficult to clean, affecting the detection accuracy of the next use, reducing the efficiency of continuous detection of concrete slump, and making it difficult to recycle the concrete after detection, which brings inconvenience to continuous detection. Therefore, a concrete slump detection device and detection method for municipal engineering construction are proposed to solve the above problems. Summary of the invention

[0017] A detection method of a concrete slump detection device for municipal engineering construction, comprising the following steps:

[0018] Step 1: The light-blocking surface contacts the infrared sensor 1 to start the motor 1, causing the gear to drive the gear ring to rotate, and the test barrel to rotate synchronously through the clamp ring, so that the concrete is dropped from the upper hopper into the test barrel. The clamp ring drives the lever to rotate synchronously, causing the lever to press six button switches in sequence every time it circles around, thereby repeatedly driving the six electric push rods 2 to achieve step-by-step extension and retraction, and the concrete in the test barrel is vibrated. At the same time, the six electric push rods 2 will hit the scraper rod to generate vibration after extending to the highest point, and the concrete is vibrated synchronously;

[0019] Step 2: Concrete in the test barrel continuously rotates along the scraper rod to prevent it from hanging on the wall. After the concrete fills the test barrel, it is scraped flat on the top of the support ring 2, and the motor 2 is turned on to rotate the screw, thereby driving the disc 2 to rise along the limit rod under the limit action of the connecting arm 2, and the clamping ring is driven to rise through the suspension rod, and the upper hopper, the support ring 1 and the test barrel are lifted synchronously, so as to achieve the collapse of the concrete;

[0020] Step 3: After the guide plate rises synchronously, the infrared sensor 1 moves away from the light-blocking surface, thereby stopping the motor 1 from working, the lever stops rotating, and the six electric push rods 2 are restored to be flush with the test plate without generating protrusions. The guide surface slides along the inclined surface of the guide plate and pushes the slide frame to slide on the support arm, thereby squeezing the spring to contract. After the test barrel rises to a high position, the concrete collapses. The visual camera is used to shoot the measuring ruler to measure the collapse height of the concrete in real time, and to shoot the extended area after the concrete collapses.

[0021] Step 4: After the test barrel rises to the highest position, the motor 2 stops intermittently. At this time, the light-blocking surface contacts the infrared sensor 2 to open the electric push rod 1, and the inner rod of the electric push rod 1 pushes the unloading plate into the test plate to push and scrape the concrete into the aggregate trough for recovery. Then the electric push rod 1 resets and drives the unloading plate back to the inner wall of the slot. The motor 2 starts intermittently and reverses, causing the test barrel to descend and reset. The spring pushes the spacer through elastic extension and drives the slide frame to reset against the guide plate;

[0022] Step 5: After the test barrel and support ring 1 are reset to the test plate, no new concrete is added. The infrared sensor 1 contacts the light-blocking surface again to cause the test barrel to rotate, and the scraper rod is used to scrape off the residual concrete on the inner wall of the test barrel. At the same time, the six electric push rods 2 repeatedly hit the scraper rod to generate vibration, thereby shaking off the residual concrete. The above steps are run empty once or more to thoroughly clean and recycle the residual concrete in the test barrel.

[0023] (III) Beneficial effects

[0024] Compared with the prior art, the present invention provides a concrete slump detection device and detection method for municipal engineering construction, which has the following beneficial effects:

[0025] 1. The concrete slump detection device and detection method for municipal engineering construction adopts efficient automatic cleaning. Through the coordinated operation of the cleaning unit and the control unit, the automatic cleaning of the inner wall of the slump cylinder is realized. When the light-blocking surface contacts the infrared sensor, the motor starts to drive the test barrel to rotate. At the same time, the lever rotates with the clamping ring, and the six button switches are pressed in sequence to drive the six electric push rods to step-by-step telescope, hit the scraper rod to generate vibration, and shake off the residual concrete on the inner wall of the test barrel. During the rotation of the test barrel, its inner wall fits with the scraper rod, which can scrape off the residual concrete. After the detection is completed, no manual cleaning is required to avoid the influence of concrete residue on the next detection accuracy, thereby improving the efficiency of continuous detection.

[0026] 2. The concrete slump detection device and detection method for municipal engineering construction adopts precise tamping and vibration. The six electric push rods of the tamping part are driven by the lever to perform continuous step-by-step tamping operations on the concrete in the test barrel, so that the bubbles in the concrete can overcome the viscous resistance and the buoyancy of the slurry and rise and be discharged, thereby improving the density of the concrete and enhancing its durability indicators such as impermeability and frost resistance. The vibration generated by the electric push rod extending to the highest point to hit the scraper rod further assists in the vibration of the concrete, ensures that the concrete is evenly compacted, and improves the accuracy of the test results.

[0027] 3. The concrete slump detection device and detection method for municipal engineering construction adopts automatic concrete recovery. The recovery part, under the control of the control part, realizes the automatic measurement and cleaning of concrete after collapse. After the test barrel rises to the highest position, the light-blocking surface contacts the second infrared sensor, and the electric push rod is started to push the discharge plate to scrape the concrete into the aggregate trough for recovery. The automated recovery process reduces manual operation, improves recovery efficiency, and provides convenience for continuous detection.

[0028] 4. The concrete slump detection device and detection method for municipal engineering construction adopts precise slump measurement and uses a visual camera in conjunction with a measuring ruler. After the concrete collapses, it can take a real-time photo of the measuring ruler to accurately measure the collapse height of the concrete. At the same time, it can also take a photo of the extended area after the concrete collapses, thereby obtaining more comprehensive and accurate detection data and providing a richer basis for evaluating the workability of concrete.

[0029] 5. The concrete slump detection device and detection method for municipal engineering construction prevents concrete from hanging on the wall. The test barrel continuously rotates along the scraper rod during the detection process, so that the concrete keeps moving in the test barrel, effectively preventing the concrete from adhering to the inner wall of the test barrel, ensuring the stability of the concrete state during the detection process, and avoiding detection errors caused by concrete hanging on the wall.

[0030] 6. The concrete slump detection device and detection method for municipal engineering construction adopts reasonable structural design, convenient operation, clear division of labor and mutual cooperation among various components. The installation part is convenient for the installation and collaborative operation of the detection tool, the loading part realizes convenient loading, and the lifting part ensures the vertical lifting and stable lifting of the slump cylinder. The overall structure is compact and reasonable, the operation process has a high degree of automation, which reduces the intensity of manual labor and improves the overall efficiency of the detection work.

[0044] In order to further improve the efficiency and thoroughness of automated concrete recycling, the recycling part 6 in this case includes an electric push rod 61, which is electrically connected to the infrared sensor 27. The infrared sensor 27 drives the electric push rod 61 to perform a reciprocating telescopic motion. The electric push rod 61 is installed on the side wall of the support arm 51.

The bottom of the blanking plate 62 is flush with the top of the test plate 1. The inner rod of the electric push rod 61 slides through the slot and is fixedly connected to the blanking plate 62. A measuring ruler 63 is embedded in the middle of the blanking plate 62. The outer rod of the electric push rod 61 is installed with a rod holder 64.

The visual camera 11 is aligned with the measuring ruler 63.

[0047] A detection method of a concrete slump detection device for municipal engineering construction, comprising the following steps:

[0048] Step 1: The light-blocking surface 54 contacts the infrared sensor 26 to start the motor 55, causing the gear 56 to drive the gear ring 43 to rotate, and the test barrel 41 to rotate synchronously through the clamp ring 42, so that the concrete is put from the upper hopper 33 into the test barrel 41, and the clamp ring 42 drives the lever 44 to rotate synchronously, causing the lever 44 to press the six button switches 46 in turn every time it circles around, thereby repeatedly driving the six electric push rods 83 to achieve step-by-step extension and retraction, and the concrete in the test barrel 41 is tamped and vibrated. At the same time, the six electric push rods 83 will hit the scraper rod 23 to generate vibration after extending to the highest point, and the concrete is vibrated synchronously;

[0049] Step 2: Concrete in the test barrel 41 is continuously rotated along the scraper rod 23 through the test barrel 41 to prevent it from hanging on the wall. After the concrete fills the test barrel 41, it is scraped flat on the top of the support ring 24, and the motor 2 74 is turned on to cause the screw 75 to rotate, thereby driving the disc 2 77 to rise along the limit rod 71 under the limiting action of the connecting arm 2 76, and driving the clamping ring 32 to rise through the suspension rod 78, and synchronously lifting the upper hopper 33, the support ring 1 21 and the test barrel 41, thereby realizing the collapse of the concrete;

[0050] Step 3: After the guide plate 25 rises synchronously, the infrared sensor 26 moves away from the light-blocking surface 54, thereby stopping the motor 55 from working, the lever 44 stops rotating, and the six electric push rods 83 are restored to be flush with the test plate 1 without generating protrusions. The guide surface 53 slides along the inclined surface of the guide plate 25 and pushes the slide frame 52 to slide on the support arm 51, thereby squeezing the spring 58 to contract. After the test barrel 41 rises to a high position, the concrete collapses. The visual camera 11 is used to shoot the measuring ruler 63 to measure the collapse height of the concrete in real time, and to shoot the extended area of ​​the concrete after collapse.

[0051] Step 4: After the test barrel 41 rises to the highest position, the motor 2 74 stops intermittently. At this time, the light-blocking surface 54 contacts the infrared sensor 2 27 to open the electric push rod 1 61, and the inner rod of the electric push rod 1 61 pushes the unloading plate 62 into the test plate 1, and the concrete is pushed and scraped into the aggregate trough 9 for recovery. Then, the electric push rod 1 61 is reset to drive the unloading plate 62 back to the inner wall of the slot, and the motor 2 74 is started intermittently and reversed to cause the test barrel 41 to descend and reset. The spring 58 pushes the spacer 57 through elastic extension and drives the slide frame 52 to reset close to the guide plate 25;

[0052] Step 5: After the test barrel 41 and the support ring 21 are reset to the test plate 1, no new concrete is added. The infrared sensor 26 contacts the light-blocking surface 54 again to cause the test barrel 41 to rotate, and the scraper 23 is used to scrape the residual concrete on the inner wall of the test barrel 41. At the same time, the six electric push rods 83 repeatedly hit the scraper 23 to generate vibration, thereby shaking off the residual concrete. The above steps are run empty once or more, and the residual concrete in the test barrel 41 can be thoroughly cleaned and recycled.

[0053] Working principle: concrete is put from the upper hopper 33 into the test barrel 41, the light-blocking surface 54 contacts the infrared sensor 26 to start the motor 55, causing the gear 56 to drive the gear ring 43 to rotate, thereby driving the test barrel 41 to rotate, and the lever 44 rotates synchronously to press the six button switches 46 in sequence, thereby driving the six electric push rods 83 to realize step-by-step telescopic movement to tamp the concrete in the barrel, making the concrete more compact and improving its use index. The electric push rod 83 will also hit the scraper rod 23 to generate vibration, thereby vibrating the concrete, and the test barrel 41 continues to rotate along the scraper rod 23 to prevent the concrete from hanging on the wall.

[0054] Turning on the second motor 74 causes the screw 75 to rotate, thereby driving the second disc 77 to rise, and driving the test barrel 41 to rise through the suspension rod 78, so as to achieve the collapse of the concrete, and the guide plate 25 rises synchronously, and the infrared sensor 26 is away from the light-blocking surface 54 to stop the operation of the motor 55, and the six electric push rods 2 83 are reset to ensure the flatness of the top of the test plate 1, and the concrete collapses. The visual camera 11 is used to shoot the measuring ruler 63 to measure the collapse height of the concrete in real time, and to shoot the extended area after the concrete collapse, so as to obtain more complete and accurate detection data.

[0055] The guide surface 53 slides along the inclined surface of the guide plate 25, and the motor 2 74 stops intermittently. At this time, the light-blocking surface 54 contacts the infrared sensor 27 to start the electric push rod 1 61, and the unloading plate 62 is pushed by the electric push rod 1 61 to push and scrape the concrete into the aggregate trough 9 for recovery. After the electric push rod 1 61 is reset, the motor 2 74 starts intermittently and reverses, prompting the test barrel 41 to descend and reset. The spring 58 pushes the light-blocking surface 54 to slide close to the guide plate 25 and reset through elastic extension, and re-contacts the light-blocking surface 54 through the infrared sensor 1 26 to prompt the test barrel 41 to rotate, and the scraper 23 is used to scrape the residual concrete on the inner wall of the test barrel 41. At the same time, the six electric push rods 2 83 hit the scraper 23 to generate vibration, thereby shaking off the residual concrete, improving the thoroughness of the residual concrete cleaning, and making the automated cleaning more efficient.

10. A detection method of a concrete slump detection device for municipal engineering construction, according to claim 9, characterized in that: The following steps are involved: Step 1: The light-blocking surface (54) contacts the infrared sensor 1 (26) to start the motor 1 (55), causing the gear (56) to drive the gear ring (43) to rotate, and the test barrel (41) to rotate synchronously through the clamp ring (42), so that concrete is dropped from the upper hopper (33) and enters the test barrel (41), and the clamp ring (42) drives the lever (44) to rotate synchronously, causing the lever (44) to press six button switches (46) in sequence every time it rotates around, thereby repeatedly driving the six electric push rods 2 (83) to achieve step-by-step extension and retraction, and the concrete in the test barrel (41) is tamped and vibrated. At the same time, after extending to the highest point, the six electric push rods 2 (83) will hit the scraper rod (23) to generate vibration, and the concrete is vibrated synchronously; Step 2: Concrete in the test barrel (41) is continuously rotated along the scraper rod (23) through the test barrel (41) to prevent it from hanging on the wall. After the concrete fills the test barrel (41), it is scraped flat on the top of the second support ring (24), and the second motor (74) is turned on to drive the screw (75) to rotate, thereby driving the second disc (77) to rise along the limit rod (71) under the limiting action of the second connecting arm (76), and driving the clamping ring (32) to rise through the suspension rod (78), and synchronously lifting the upper hopper (33), the first support ring (21) and the test barrel (41), thereby achieving the collapse of the concrete; Step 3: After the guide plate (25) rises synchronously, the infrared sensor 1 (26) moves away from the light blocking surface (54) to stop the motor 1 (55) from working, the lever (44) stops rotating, the six electric push rods 2 (83) are all restored to be flush with the test plate (1) without generating any protrusions, the guide surface (53) slides along the inclined surface of the guide plate (25) and pushes the slide frame (52) to slide on the support arm (51), thereby squeezing the spring (58) to contract, after the test barrel (41) rises to a high position, the concrete collapses, and the visual camera (11) is used to shoot the measuring ruler (63) to measure the collapse height of the concrete in real time, and to shoot the extended area of ​​the concrete after collapse; Step 4: After the test barrel (41) rises to the highest position, the second motor (74) stops intermittently. At this time, the light-blocking surface (54) contacts the second infrared sensor (27) to open the first electric push rod (61). The inner rod of the first electric push rod (61) pushes the unloading plate (62) into the test plate (1), and the concrete is pushed and scraped into the collecting trough (9) for recovery. Then, the first electric push rod (61) is reset to drive the unloading plate (62) back to the inner wall of the slot. The second motor (74) is started intermittently and reversed to cause the test barrel (41) to descend and reset. The spring (58) pushes the spacer (57) through elastic extension and drives the slide frame (52) to be close to the guide plate (25) for reset. Step 5: After the test barrel (41) and the support ring (21) are reset on the test plate (1), no new concrete is added. The infrared sensor (26) contacts the light-blocking surface (54) again to cause the test barrel (41) to rotate, and the scraper (23) is used to scrape the residual concrete on the inner wall of the test barrel (41). At the same time, the six electric push rods (83) repeatedly hit the scraper (23) to generate vibration, thereby shaking off the residual concrete. The above steps are performed once or more without any work, and the residual concrete in the test barrel (41) can be completely cleaned and recycled.
