Description

Technical Field

[0001] This utility model belongs to the field of cement moisture content monitoring technology, and in particular relates to a device for monitoring the moisture content of cement stabilized materials. Background Technology

[0002] Cement stabilized materials are a commonly used road construction material. They are mixtures made by mixing cement with various aggregates, such as graded crushed stone, graded gravel, and unscreened crushed stone, and adding water. Cement plays a key role in this process, binding the aggregate particles together to give them a certain strength and stability.

[0003] In the construction of cement-stabilized materials, a suitable moisture content is crucial for achieving good compaction results. If the moisture content is too low, the friction between material particles is too large, making it difficult for them to come close together during rolling, resulting in insufficient compaction. When the moisture content is too high, the material is prone to the "spring" phenomenon during rolling, that is, the material undergoes elastic deformation under the action of the roller, making it impossible to form a stable structural layer. During testing, a capacitive moisture content monitoring device can detect the moisture content of cement-stabilized materials. The capacitive moisture content monitoring device mainly includes a capacitive sensor probe, a signal processing unit, and a display unit.

[0004] Currently, existing capacitive moisture content monitoring devices are typically fixed installations. The probe position of these devices is determined during installation, which may result in blind spots in the mixing unit or material storage area. In large cement stabilizer mixing drums, fixed probes may only be able to monitor a small area nearby, and cannot effectively monitor moisture content changes at the edges and bottom corners of the mixing drum or near the feed inlet.

[0005] To address the aforementioned issues, this application proposes a device for monitoring the moisture content of cement-stabilized materials. Utility Model Content

[0006] The purpose of this invention is to provide a device for monitoring the moisture content of cement-stabilized materials, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a moisture content monitoring device for cement-stabilized materials, comprising a monitoring body. A display and a controller are respectively installed on the left side of the monitoring body. A storage battery is installed inside the monitoring body. Two support frames are fixedly connected to the upper surface of the monitoring body. A telescopic rod is rotatably connected to the inner wall of each support frame. A gear is fixedly connected to the telescopic end of each telescopic rod, and the outer surface of each gear contacts the inner wall of the support frame. An electric push rod and a sensing probe are respectively installed above the monitoring body. The ends of the two telescopic rods that are close to each other are fixedly connected to the outer surface of the electric push rod. A telescopic flexible cable is fixedly connected to the input end of the monitoring body, and the top end of the telescopic flexible cable is fixedly connected to the output end of the sensing probe.

[0009] Furthermore, a fixing plate is fixedly connected to the right side of both the display and the controller, and the right side of the fixing plate is fixedly connected to the left side of the monitoring body.

[0010] Furthermore, two fixing frames are fixedly connected to both the front and back of the monitoring subject, and a handle is fixedly connected to the inner wall of each set of fixing frames.

[0011] Furthermore, the right side of the monitoring body is hinged to an opening and closing door, and the right side of the opening and closing door is fixedly connected to a handle.

[0012] Furthermore, a connecting rod is fixedly connected to each of the two gears on their opposite sides, and a turning ring is fixedly connected to each of the opposite ends of the two connecting rods.

[0013] Furthermore, a reinforcing ring is fixedly connected to the telescopic end of the electric push rod, and the inner wall of the reinforcing ring is fixedly connected to the outer surface of the sensing probe.

[0014] Furthermore, the outer surface of the electric push rod is fixedly connected with equidistant limit frames, each of which is sleeved on the outside of the telescopic flexible cord.

[0015] This utility model has the following beneficial effects:

[0016] This utility model, through the sensing of the sensor probe, can transmit information to the monitoring body via a retractable cord. The monitoring body can then analyze the information and transmit the data to the display, thereby monitoring the moisture content of cement stabilizing materials. Simultaneously, through the storage battery, the power can be stored and installed in the monitoring body to provide power for the equipment, further facilitating the mobile monitoring use of the equipment.

[0017] This utility model is equipped with a controller that can turn the device on and off or adjust its direction. At the same time, the extension and retraction of the electric push rod can drive the sensing probe and the monitoring body to move away from or closer to each other. The extension and retraction of the telescopic rod can drive the gear to contact or disengage from the support frame. The rotation of the telescopic rod on the support frame can adjust and limit the angle of the electric push rod, thereby allowing the sensing probe to be used by adjusting the angle and distance. The extension and retraction of the telescopic cable can keep the monitoring body and the sensing probe connected at all times as the sensing probe moves, and further allows the sensing probe to be easily moved to different positions for monitoring.

[0018] In summary, by installing a sensor probe, information can be transmitted to the monitoring unit via a telescopic cable. The monitoring unit, in conjunction with a display, can show the moisture content of the cement stabilizing material. A battery, in conjunction with a controller, provides power and controls the equipment. The telescopic rod's rotation on the support frame and its own extension / retraction can cause gears to engage or disengage with the support frame, allowing the telescopic rod to drive an electric push rod to adjust its angle or limit its movement. The extension / retraction of the electric push rod, in turn, moves the sensor probe. Furthermore, the telescopic cable ensures constant communication between the sensor probe and the monitoring unit, facilitating mobile monitoring and preventing situations where the equipment can only monitor from a single location.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A gear 13 is fixedly connected to the telescopic end of each telescopic rod 12. The outer surface of each gear 13 is in contact with the inner wall of the support frame 5. An electric push rod 4 and a sensing probe 16 are respectively arranged above the monitoring body 1. The ends of the two telescopic rods 12 that are close to each other are fixedly connected to the outer surface of the electric push rod 4. A telescopic flexible cable 19 is fixedly connected to the input end of the monitoring body 1. The top end of the telescopic flexible cable 19 is fixedly connected to the output end of the sensing probe 16. In this embodiment, the telescopic flexible cable 19 can move with the sensing probe 16 through its own extension and contraction and its soft material, and keep the sensing probe 16 and the monitoring body 1 in constant communication.

[0031] In this embodiment, the right side of the display 2 and the controller 3 are fixedly connected to the fixing plate 6. The right side of the fixing plate 6 is fixedly connected to the left side of the monitoring body 1. In this embodiment, the fixing plate 6 can fix the display 2 and the controller 3 to the monitoring body 1. The display 2 is a display tool that displays certain electronic documents on the screen through a specific transmission device and then reflects them to the human eye. The controller 3 is a master control device that controls the starting, speed adjustment, braking and reversing of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence.

[0032] The monitoring body 1 has two fixed brackets 9 fixedly connected to its front and back sides. Each set of fixed brackets 9 has a handle 10 fixedly connected to its inner wall. In this embodiment, the fixed brackets 9 can fix the handle 10 to the monitoring body 1, and the handle 10 can be used to move the monitoring body 1.

[0033] The monitoring body 1 is movably hinged to the right side of the door 8, and the right side of the door 8 is fixedly connected to the handle 7. In this embodiment, the monitoring body 1 can be easily opened or closed through the door 8, and the door 8 can be easily opened or closed using the handle 7.

[0034] In this embodiment, the connecting rods 14 are fixedly connected to the two gears 13 on their opposite sides, and the rotating rings 15 are fixedly connected to the opposite ends of the two connecting rods 14. In this embodiment, the rotating rings 15 can be fixed to the gears 13 by the connecting rods 14, and the gears 13 can be moved easily by the rotating rings 15.

[0035] The telescopic end of the electric push rod 4 is fixedly connected to a reinforcing ring 17. The inner wall of the reinforcing ring 17 is fixedly connected to the outer surface of the sensing probe 16. In this embodiment, the sensing probe 16 can be fixed on the electric push rod 4 through the reinforcing ring 17, thereby improving the stability of the sensing probe 16.

[0036] Among them, the outer surface of the electric push rod 4 is fixedly connected with equidistant limit frames 18, each of which is sleeved on the outside of the telescopic cord 19. In this embodiment, the telescopic cord 19 can be limited by the limit frames 18, thereby improving the stability of the telescopic cord 19 during use.

[0037] Understandably, the battery 11, in conjunction with the controller 3, enables the monitoring body 1 to be used for mobile monitoring. The sensor 16, along with the telescopic cable 19, the monitoring body 1, and the display 2, allows for monitoring of the moisture content of the cement stabilized material. Simultaneously, the extension and retraction of the telescopic rod 12, and its rotation on the support frame 5, allow the gear 13 to contact or disengage from the support frame 5. This enables the telescopic rod 12 to rotate the electric push rod 4 and limit its movement. The extension and retraction of the electric push rod 4 extends the monitoring distance of the sensor 16. Furthermore, the extension and retraction of the telescopic cable 19 ensures that the sensor 16, the monitoring body 1, and the display 2 remain connected at all times, thus improving the convenience of mobile monitoring and allowing for convenient monitoring of multiple locations of the cement stabilized material.

[0038] A specific application of this embodiment is as follows: In use, firstly, connect the battery 11 to the power supply. When it is necessary to monitor the moisture content of the cement stabilized material, open the door 8 using the handle 7, and simultaneously install the battery 11 into the monitoring body 1. Connect the monitoring body 1, display 2, sensor probe 16, controller 3, and electric push rod 4 to the battery 11 via wires. Simultaneously, connect the electric push rod 4 to the controller 3 via wires. Then, the operator uses the lever 10 in conjunction with the fixing frame 9 to move the monitoring body 1 to a suitable position. Simultaneously, the controller 3 opens and extends the electric push rod 4, causing the sensor probe 16 to move. When the sensor probe 16 moves, the retractable cable 19 follows, maintaining constant communication between the sensor probe 16 and the monitoring body 1. When the sensor probe 16 comes into contact with the cement stabilized material, the sensor probe... Information 16 is transmitted to the monitoring body 1 for analysis via the telescopic flexible cable 19. The analysis by the monitoring body 1 transmits the values ​​to the display 2 for display, allowing staff to monitor the moisture content of the cement stabilized material. Then, by turning the ring 15 in conjunction with the connecting rod 14, the gear 13 is pulled, causing the gear 13 to move out of the support frame 5 through the extension and retraction of the telescopic rod 12. Simultaneously, rotating the ring 15 and the connecting rod 14 causes the gear 13 and the telescopic rod 12 to rotate on the support frame 5, thereby causing the telescopic rod 12 to drive the electric push rod 4 and the sensing probe 16 to adjust their positions. After adjustment, the gear 13 is pressed again, causing the gear 13 to move into the support frame 5 through the extension and retraction of the telescopic rod 12, thereby limiting the angle between the electric push rod 4 and the sensing probe 16. When the sensing probe 16 moves, it can monitor different positions of the cement stabilized material, further improving the comprehensiveness of the moisture content monitoring of the cement stabilized material.
