Description

Technical Field

[0001] This application relates to the field of material performance monitoring technology, and in particular to a device for monitoring the volume stability of base mixtures. Background Technology

[0002] With technological advancements, new types of eco-friendly cement derived from recycled solid waste are increasingly emerging, with industrial solid waste playing a crucial role as a cementing material in meeting usage requirements. The emergence of these new cements has positively impacted resource recycling and environmental protection, propelling the building materials industry towards a greener and more sustainable direction. However, industrial solid waste, as a cementing material, is accompanied by uncertainties in volume changes, and current standards for base course materials lack provisions regarding volume stability. The impact of volume changes in base course mixtures on roads in practical applications is significant, and the lack of suitable monitoring equipment hinders the widespread application of these materials. In monitoring the volume stability of base course mixtures, the conventional approach is to use unrestricted monitoring methods. Specifically, conventional volume stability monitoring specimens are unrestricted in all directions, allowing volume changes to occur in any direction. This monitoring method was widely used in the past because it is relatively simple to operate and does not require complex equipment and technology. In practice, monitoring personnel typically place the specimen in an open environment, allowing it to deform freely, and then record the volume changes using simple measuring tools. This method can reflect the volume change of materials to some extent, but because it lacks consideration of practical application scenarios, the monitoring results may differ significantly from the actual conditions of the materials in use. Therefore, in view of the above situation, there is an urgent need to develop a volume stability monitoring device for base course mixtures to overcome the shortcomings in current practical applications. Utility Model Content

[0003] To address the deficiencies in the aforementioned technologies, this application provides a device for monitoring the volume stability of base mixtures.

[0004] This application provides a device for monitoring the volume stability of a base course mixture, which adopts the following technical solution: A device for monitoring the volume stability of a base mixture includes an adjusting mechanism, a limiting mechanism, and a monitoring mechanism, wherein the limiting mechanism is disposed on the adjusting mechanism and the monitoring mechanism is disposed on the limiting mechanism.

[0005] Beneficial effects: The limiting mechanism, mounted on the adjusting mechanism, primarily functions to precisely fix and accommodate the base mixture and mold to be monitored, ensuring the specimen remains in a fixed position without shifting during monitoring. The monitoring mechanism, then mounted on the limiting mechanism, directly collects and monitors volume change data of the specimen fixed by the limiting mechanism. This modularizes the complex monitoring function into three main modules: adjusting, limiting, and monitoring. This results in a clear device structure, well-defined functions, and high integration, facilitating manufacturing, installation, and use, thus laying the foundation for accurate monitoring.

[0006] In one optional embodiment, the adjusting mechanism includes a base frame, on which a driving lifting screw, a first driven lifting screw, a second driven lifting screw, and a third driven lifting screw are vertically rotatably mounted respectively. The driving lifting screw, the first driven lifting screw, the second driven lifting screw, and the third driven lifting screw have the same dimensions. A placement cavity is formed in the base frame, and a driving component is disposed in the placement cavity. The driving component is drivenly connected to the driving lifting screw. The first driven lifting screw, the second driven lifting screw, and the third driven lifting screw are drivenly connected to the driving lifting screw through a transmission assembly.

[0007] Beneficial effects: The four-corner synchronous lead screw lifting design ensures that the adjustment mechanism is extremely stable during the lifting process and will not tilt, providing a stable reference plane for the upper mechanism. The design of the built-in drive component and transmission components makes the structure compact and the power transmission efficient and reliable.

[0008] In one optional embodiment, the driving end of the driving member is provided with a first bevel gear, the lower part of the active lifting screw is fixedly provided with a second bevel gear, the first bevel gear meshes with the second bevel gear for transmission, the lower part of the first driven lifting screw is fixedly provided with a third bevel gear, the lower part of the second driven lifting screw is fixedly provided with a fourth bevel gear, and the lower part of the third driven lifting screw is fixedly provided with a fifth bevel gear.

[0009] Beneficial effects: Through the transmission of the third, fourth, and fifth bevel gears with the transmission components, the power is transmitted laterally to the other lead screws, thereby realizing the synchronous movement of the first driven lifting lead screw, the second driven lifting lead screw, and the third driven lifting lead screw driven by the active lead screw.

[0010] In one optional embodiment, limit plates are respectively provided on the top of the active lifting screw, the first driven lifting screw, the second driven lifting screw, and the third driven lifting screw.

[0011] Beneficial effect: The limiting plate, as a mechanical stop block, is fixed to the top of the lead screw. When the lead screw rotates and drives the limiting plate on it to rise, the limiting plate will come into contact with the limiting plate after rising to the top of the lead screw, thus being physically blocked and preventing it from accidentally falling off the lead screw.

[0012] In one optional embodiment, the transmission assembly includes three limiting plates, which are fixedly disposed on the bottom surface of the placement cavity. A first rotating rod, a second rotating rod, and a third rotating rod are respectively horizontally rotatably disposed on the three limiting plates. The first rotating rod is disposed between the active lifting screw and the first driven lifting screw; the second rotating rod is disposed between the first driven lifting screw and the second driven lifting screw; and the third rotating rod is disposed between the second driven lifting screw and the third driven lifting screw. A sixth bevel gear is disposed at each end of the first, second, and third rotating rods. At one end of the first rotating rod, the sixth bevel gear meshes with the second bevel gear, and at the other end, the sixth bevel gear meshes with the third bevel gear. At one end of the second rotating rod, the sixth bevel gear meshes with the third bevel gear, and at the other end, the sixth bevel gear meshes with the fourth bevel gear. At one end of the third rotating rod, the sixth bevel gear meshes with the fourth bevel gear, and at the other end, the sixth bevel gear meshes with the fifth bevel gear.

[0013] Beneficial effects: The sixth bevel gears at both ends of the first rotating rod mesh with the second bevel gear of the driving lead screw and the third bevel gear of the first driven lead screw, respectively, transmitting power from the driving lead screw to the first driven lead screw. Similarly, the second rotating rod transmits power from the first driven lead screw to the second driven lead screw, and the third rotating rod transmits power from the second driven lead screw to the third driven lead screw. Through the meshing of the multi-stage bevel gear set, synchronous drive of the four corner lead screws by a single power source is achieved.

[0014] The clearly defined power transmission chain makes synchronous drive more precise, and the limit plate ensures the stability of the rotating rod, allowing it to rotate but not move, thus improving the smoothness and accuracy of the transmission.

[0015] In one optional embodiment, the limiting mechanism includes a limiting plate, which is horizontally disposed on the active lifting screw, the first driven lifting screw, the second driven lifting screw, and the third driven lifting screw. The limiting plate is threadedly connected to the lifting screw. The limiting plate has a placement groove, and each end of the placement groove has a locking slot. A locking block is slidably disposed in the locking slot. Multiple connecting slots are provided in the locking slot, and the connecting slots are bolted to the locking blocks.

[0016] Beneficial effects: The limiting mechanism achieves dual functions: firstly, it moves up and down as a whole with the adjustment mechanism; secondly, it can flexibly fix specimen molds of different sizes, greatly improving the versatility and applicability of the device. The adjustment method of the locking block and the connecting groove is simple and reliable, and the fixing effect is good.

[0017] In one optional embodiment, the placement groove is provided with a mold for placing the base mixture, and test ports are opened at both ends of the mold.

[0018] Beneficial effects: Standardized specimen shape and size ensure consistent testing conditions, making experimental results comparable. Different molds can be used to hold different specimens if needed. Dedicated testing ports ensure that the monitoring agency can accurately and directly align with the test area, reducing interference and improving the accuracy and reliability of monitoring data.

[0019] In one optional embodiment, the monitoring mechanism includes a moving groove, a plurality of moving grooves are provided on the limiting plate, a moving block is slidably disposed in the moving groove, an adjusting screw is disposed on the moving block, and a monitoring component is disposed on the adjusting screw.

[0020] Beneficial effects: This structure allows the operator to first roughly adjust the approximate horizontal position of the monitoring component by sliding the moving block, and then fine-tune it by rotating the adjusting screw, so that the measuring head of the monitoring component (such as a displacement sensor) is precisely aligned with the test port on the mold.

[0021] In one optional embodiment, the monitoring component includes a processing unit for processing monitoring information, a plurality of displacement sensors for monitoring the base mixture in the mold, and a storage unit for storing information, wherein the processing unit, the monitoring head, and the storage unit are electrically connected.

[0022] Beneficial effects: The displacement sensor monitors the displacement change (i.e., volume deformation) of the base mixture in the mold in the direction of the test port in real time, and converts the displacement data into an electrical signal and transmits it to the processing unit (such as a microprocessor). The processing unit collects, calculates and analyzes the data, while the storage unit is responsible for storing the processed data and time information for subsequent query, export or further analysis.

[0023] In summary, this application includes at least one of the following beneficial technical effects: The limiting mechanism is installed on the adjusting mechanism. Its main function is to precisely fix and accommodate the base mixture and mold to be monitored, ensuring that the specimen remains in a fixed position without shifting during the monitoring process. The monitoring mechanism is then installed on the limiting mechanism to directly collect and monitor the volume change data of the specimen fixed by the limiting mechanism. The three mechanisms are interconnected and work together to monitor the volume stability of the specimen. Attached Figure Description

[0026] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0029] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0030] The present invention provides the following embodiments. Example 1 This application discloses a device for monitoring the volume stability of a base mixture, referring to... Figure 1 It includes an adjustment mechanism 1, a limiting mechanism 2 and a monitoring mechanism 3, wherein the limiting mechanism 2 is disposed on the adjustment mechanism 1 and the monitoring mechanism 3 is disposed on the limiting mechanism 2.

[0031] The working principle and beneficial effects of the above technical solution are as follows: The device provides overall height and level adjustment functions through the adjustment mechanism 1, providing a stable and adaptable reference platform for the monitoring mechanism 3. The limiting mechanism 2 is installed on the adjustment mechanism 1, and its main function is to accurately fix and accommodate the base mixture 4 and the mold 26 to be monitored, ensuring that the specimen is fixed in position and does not shift during the monitoring process. The monitoring mechanism 3 is then installed on the limiting mechanism 2, directly collecting and monitoring the volume change data of the specimen fixed by the limiting mechanism 2. The three mechanisms are interconnected and work together to jointly complete the monitoring of the volume stability of the specimen.

[0032] By modularizing the complex monitoring functions into three main modules—adjustment, limit, and monitoring—the device has a clear structure, well-defined functions, and high integration, making it easy to manufacture, install, and use, thus laying the foundation for accurate monitoring.

[0033] like Figures 1-3As shown, the adjustment mechanism 1 includes a base frame 11. At the four corners of the base frame 11, a driving lifting screw 12, a first driven lifting screw 13, a second driven lifting screw 14, and a third driven lifting screw 15 are vertically rotatably mounted. The driving lifting screw 12, the first driven lifting screw 13, the second driven lifting screw 14, and the third driven lifting screw 15 have the same dimensions. A placement cavity 111 is formed inside the base frame 11, and a driving component 16 is disposed within the placement cavity 111. The driving component 16 is driveably connected to the driving lifting screw 12. The first driven lifting screw 13, the second driven lifting screw 14, and the third driven lifting screw 15 are driveably connected to the driving lifting screw 12 through a transmission assembly.

[0034] The working principle and beneficial effects of the above technical solution are as follows: the drive component 16 drives the active lifting screw 12 connected to it to rotate. The active lifting screw 12 then transmits power synchronously to the first driven lifting screw 13, the second driven lifting screw 14, and the third driven lifting screw 15 through the transmission component. Since the active lifting screw 12, the first driven lifting screw 13, the second driven lifting screw 14, and the third driven lifting screw 15 are the same size and are driven synchronously, they will rotate at the same speed and direction. The limiting mechanism 2, which is connected to the active lifting screw 12, the first driven lifting screw 13, the second driven lifting screw 14, and the third driven lifting screw 15 through threads, can achieve smooth vertical lifting, thereby completing the height adjustment and leveling of the entire device.

[0035] The design of four-corner synchronous lead screw lifting ensures that the adjustment mechanism 1 is extremely stable during the lifting process and will not tilt, providing a stable reference plane for the upper mechanism. The design of the built-in drive component 16 and transmission components makes the structure compact and the power transmission efficient and reliable.

[0036] like Figures 1-3 As shown, the driving end of the driving component 16 is provided with a first bevel gear 161, the lower part of the active lifting screw 12 is fixedly provided with a second bevel gear 121, the first bevel gear 161 and the second bevel gear 121 mesh and drive each other, the lower part of the first driven lifting screw 13 is fixedly provided with a third bevel gear 131, the lower part of the second driven lifting screw 14 is fixedly provided with a fourth bevel gear 141, and the lower part of the third driven lifting screw 15 is fixedly provided with a fifth bevel gear 151.

[0037] The working principle and beneficial effects of the above technical solution are as follows: the horizontal rotational power output by the drive component 16 is converted into the vertical rotation of the active lifting screw 12 through the meshing of the first bevel gear 161 and the second bevel gear 121. At the same time, through the transmission of the third bevel gear 131, the fourth bevel gear 141 and the fifth bevel gear 151 with the transmission component, the power is transmitted laterally to other screws, thereby realizing the synchronous movement of the active screw driving the first driven lifting screw 13, the second driven lifting screw 14 and the third driven lifting screw 15.

[0038] The bevel gear meshing method is a reliable mechanical structure for realizing the change of power direction and lateral transmission. This design has high transmission efficiency, a robust structure, and can withstand large loads, ensuring the accuracy and reliability of the synchronous movement of the active lifting screw 12, the first driven lifting screw 13, the second driven lifting screw 14, and the third driven lifting screw 15.

[0039] like Figures 1-3 As shown, limit plates 17 are respectively provided on the top of the active lifting screw 12, the first driven lifting screw 13, the second driven lifting screw 14, and the third driven lifting screw 15.

[0040] The working principle and beneficial effects of the above technical solution are as follows: The limiting plate 17, as a mechanical stop block, is fixed on the top of the active lifting screw 12, the first driven lifting screw 13, the second driven lifting screw 14, and the third driven lifting screw 15. When the active lifting screw 12, the first driven lifting screw 13, the second driven lifting screw 14, and the third driven lifting screw 15 rotate and drive the limiting plate 21 on them to rise, the limiting plate 21 will contact the limiting plate 17 after rising to the top of the four screws, thus being physically blocked and preventing it from accidentally falling off the active lifting screw 12, the first driven lifting screw 13, the second driven lifting screw 14, and the third driven lifting screw 15.

[0041] like Figures 1-3As shown, the transmission assembly includes three limiting plates 21, which are fixedly disposed on the bottom surface of the placement cavity 111. A first rotating rod 112, a second rotating rod 113, and a third rotating rod 114 are respectively horizontally rotatably disposed on the three limiting plates 21. The first rotating rod 112 is disposed between the active lifting screw 12 and the first driven lifting screw 13; the second rotating rod 113 is disposed between the first driven lifting screw 13 and the second driven lifting screw 14; and the third rotating rod 114 is disposed between the second driven lifting screw 14 and the third driven lifting screw 15. The ends of the first rotating rod 112, the second rotating rod 113, and the third rotating rod 114 are respectively... A sixth bevel gear 115 is provided. One end of the first rotating rod 112 is connected to the second bevel gear 121 via the sixth bevel gear 115, and the other end of the first rotating rod 112 is connected to the third bevel gear 131 via the sixth bevel gear 115. One end of the second rotating rod 113 is connected to the third bevel gear 131 via the sixth bevel gear 115, and the other end of the second rotating rod 113 is connected to the fourth bevel gear 141 via the sixth bevel gear 115. One end of the third rotating rod 114 is connected to the fourth bevel gear 141 via the sixth bevel gear 115, and the other end of the second rotating rod 113 is connected to the fifth bevel gear 151 via the sixth bevel gear 115.

[0042] The working principle and beneficial effects of the above technical solution are as follows: The sixth bevel gears 115 at both ends of the first rotating rod 112 mesh with the second bevel gear 121 of the driving lead screw and the third bevel gear 131 of the first driven lifting lead screw 13, respectively, to transmit power from the driving lifting lead screw 12 to the first driven lifting lead screw 13. Similarly, the second rotating rod 113 transmits power from the first driven lifting lead screw 13 to the second driven lifting lead screw 14, and the third rotating rod 114 transmits power from the second driven lifting lead screw 14 to the third driven lifting lead screw 15. Through the meshing of the multi-stage bevel gear set, the synchronous drive of the four corner lead screws by a single power source is realized.

[0043] The power transmission chain is clearly defined, making synchronous drive more precise. The limiting plate 21 ensures the stability of the first rotating rod 112, the second rotating rod 113, and the third rotating rod 114, so that they can only rotate and cannot move, thereby improving the smoothness and accuracy of the transmission.

[0044] like Figures 1-3As shown, the limiting mechanism 2 includes a limiting plate 21, which is horizontally disposed on the active lifting screw 12, the first driven lifting screw 13, the second driven lifting screw 14, and the third driven lifting screw 15. The limiting plate 21 is threadedly connected to the lifting screw. The limiting plate 21 has a placement groove 22, and each end of the placement groove 22 has a locking groove 23. A locking block 24 is slidably disposed in the locking groove 23. Multiple connecting grooves 25 are provided in the locking groove 23, and the connecting grooves 25 are bolted to the locking blocks 24.

[0045] The working principle and beneficial effects of the above technical solution are as follows: The limiting plate 21 is screwed onto the active lifting screw 12, the first driven lifting screw 13, the second driven lifting screw 14, and the third driven lifting screw 15 through its threaded hole. When the active lifting screw 12, the first driven lifting screw 13, the second driven lifting screw 14, and the third driven lifting screw 15 rotate synchronously, the limiting plate 21 will perform a vertical lifting movement. The placement groove 22 is used to hold the mold 26 of the base mixture 4. By sliding the locking block 24 and fixing it with bolts at different positions of the connecting groove 25, the distance between the two locking blocks 24 can be changed, thereby adapting and clamping molds 26 of different sizes and preventing them from moving horizontally.

[0046] The limiting mechanism 2 achieves a dual function: firstly, it moves up and down as a whole with the adjusting mechanism 1; secondly, it can flexibly fix specimen molds 26 of different sizes, greatly improving the versatility and applicability of the device. The adjustment method of the locking block 24 and the connecting groove 25 is simple and reliable, and the fixing effect is good.

[0047] like Figures 1-3 As shown, the placement groove 22 is provided with a mold 26 for placing the base mixture 4, and test ports are opened at both ends of the mold 26.

[0048] The working principle and beneficial effects of the above technical solution are as follows: the mold 26 is a container that directly holds the base mixture 4, and the test ports at both ends provide a direct access channel for the measuring head of the monitoring mechanism 3 (such as displacement sensor 34), allowing the measuring head to contact the surface of the specimen or approach the specimen to monitor its deformation in this direction.

[0049] The standardized shape and size of the specimens ensure the consistency of the test conditions and make the experimental results comparable. Different molds 26 can be used to hold different samples if needed. The dedicated test port ensures that the monitoring mechanism 3 can accurately and directly align with the area to be tested, reducing interference and improving the accuracy and reliability of the monitoring data.

[0050] like Figures 1-3As shown, the monitoring mechanism 3 includes a moving groove 31, and a plurality of moving grooves 31 are provided on the limiting plate 21. A moving block 32 is slidably arranged in the moving groove 31, and an adjusting screw 33 is provided on the moving block 32. A monitoring component is provided on the adjusting screw 33. The monitoring component includes a processing unit 35 for processing monitoring information, multiple displacement sensors 34 for monitoring the base mixture 4 inside the mold 26, and a storage unit 36 ​​for storing information. The processing unit 35, the monitoring head, and the storage unit 36 ​​are electrically connected.

[0051] The working principle and beneficial effects of the above technical solution are as follows: the monitoring component is mounted on the moving block 32 by adjusting screw 33, and the moving block 32 can slide in the moving groove 31. This structure allows the operator to first roughly adjust the approximate horizontal position of the monitoring component by sliding the moving block 32, and then make fine adjustments by rotating the adjusting screw 33, so that the measuring head of the monitoring component (such as displacement sensor 34) is accurately aligned with the test port on the mold 26.

[0052] It provides a dual adjustment mechanism of coarse and fine adjustment, which makes the alignment operation of the monitoring mechanism 3 very flexible and precise. This ensures that no matter how the mold 26 is placed, the monitoring head can be precisely adjusted to the optimal measurement position, which greatly improves the accuracy and repeatability of the measurement.

[0053] The displacement sensor 34 monitors the displacement change (i.e., volume deformation) of the base mixture 4 in the test port direction in real time within the mold 26, and converts the displacement data into an electrical signal to be transmitted to the processing unit 35 (such as a microprocessor). The processing unit 35 collects, calculates and analyzes the data, while the storage unit 36 ​​is responsible for storing the processed data and time information for subsequent querying, export or further analysis.

[0054] This system automates, intelligentizes, and digitizes the monitoring process, enabling real-time, continuous, and accurate recording of specimen deformation data, thus avoiding errors and discontinuities inherent in manual measurements. The stored data facilitates subsequent in-depth analysis, report generation, and traceability of the experimental process, significantly improving the efficiency and scientific rigor of monitoring.

[0055] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
