Description

Technical Field

[0001] This utility model relates to the field of asphalt pavement, and in particular to an asphalt pavement temperature monitoring and early warning device. Background Technology

[0002] The safety impact of highway subsidence on high-speed vehicles has gradually gained attention. Currently, highway subsidence is usually measured manually by professional surveyors using civil engineering surveying instruments such as theodolites and levels. This allows for the determination and monitoring of subsidence conditions and values ​​in various road sections.

[0003] Chinese patent CN206556640U discloses a highway subsidence measuring device. This device uses LED beads to effectively compensate for the light intensity in the measurement environment, making the measurement results clearer and reducing measurement errors. The solar panel enables solar charging, ensuring a reliable power supply for the LED beads, making the power supply more low-carbon and environmentally friendly. The cooperation between the measuring rod and the measuring mark can effectively measure the depth of road subsidence, making the measurement method more convenient.

[0004] While the aforementioned utility model can achieve low-carbon and environmentally friendly detection through the use of measuring rods and measuring markers, it requires manual recording after monitoring. Subsequently, engineers need to remind road maintenance personnel to maintain and repair the road surface. However, due to changes in light intensity over time, some defects may not be clearly visible, leading to the problem of missed defects. Therefore, it is necessary to design an asphalt pavement temperature monitoring and early warning device to assist engineers in laying an appropriate amount of asphalt. Utility Model Content

[0005] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides an asphalt pavement temperature monitoring and early warning device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an asphalt pavement temperature monitoring and early warning device, comprising a mounting base, a traction component, a road tester, a power supply board, a marking device, an early warning device, and a monitoring sensor. The traction component is mounted on the right end of the mounting base. The road tester is fixed to the top of the mounting base. A power supply board is mounted on the top of the road tester. The marking device is mounted on the left end of the road tester. The early warning device is electrically connected to the outside of the marking device and is fixed to the front end of the road tester. The monitoring sensor is mounted on the road tester. At the right end of the device, the marking device includes an installation cylinder, a liquid injection hole, a drive motor, a refining shaft, a liquid pump, a liquid injection plate, and a marking mechanism. The installation cylinder is fixed to the left end of the mounting base. The liquid injection hole is located at the top of the installation cylinder. The drive motor is connected to the top of the installation cylinder via a drive connection. The drive motor is connected to the top of the refining shaft via a coupling. The refining shaft is rotatably connected to the inside of the installation cylinder. The liquid pump is installed inside the installation cylinder. The liquid injection plate is mounted on the left end of the liquid pump. The marking mechanism is slidably connected to the inside of the liquid injection plate.

[0007] As an improvement to the asphalt pavement temperature monitoring and early warning device, the marking device includes an installation cylinder, an injection hole, a drive motor, a refining shaft, a pump, an injection plate, and a marking mechanism. The installation cylinder is fixed to the left end of the mounting base. The injection hole is located at the top of the installation cylinder. The drive motor is connected to the top of the installation cylinder via a coupling. The refining shaft is rotatably connected to the inside of the installation cylinder. The pump is installed inside the installation cylinder. The injection plate is mounted on the left end of the pump. The marking mechanism is slidably connected to the inside of the injection plate.

[0008] As an improvement to the asphalt pavement temperature monitoring and early warning device, the installation cylinder is equipped with a partition, and the liquid pump and marking mechanism are vertically arranged inside the installation cylinder.

[0009] As an improvement to the asphalt pavement temperature monitoring and early warning device, the overall structure of the injection plate is a hollow disc structure, and the inside of the injection plate is provided with square injection holes.

[0010] As an improvement to the asphalt pavement temperature monitoring and early warning device, the left end of the mounting slider is provided with a groove that slides in cooperation with the inside of the guide frame, which ensures that the mounting slider can slide vertically under the guidance of the right end of the guide frame.

[0011] As an improvement to the asphalt pavement temperature monitoring and early warning device, the internal size of the pressure plate matches the internal size of the injection plate, and the pressure plate can be incorporated into the injection plate, so that the suction cotton set below the pressure plate can absorb the paint liquid.

[0012] As an improvement to the asphalt pavement temperature monitoring and early warning device, the suction cotton is vertically installed at the bottom of the pressure plate.

[0013] As an improvement to the asphalt pavement temperature monitoring and early warning device, the road tester can use a TH-type pavement condition detector, and the early warning device and monitoring sensor utilize the monitoring equipment in the pavement defect detection system.

[0014] Compared with the prior art, this utility model provides an asphalt pavement temperature monitoring and early warning device, which has the following beneficial effects:

[0015] Advantage 1: This utility model incorporates a marking device. Pigment and water are pre-injected into the mounting cylinder through the injection hole. The drive motor rotates the refining shaft, allowing the pigment and water to mix thoroughly inside the mounting cylinder. A pump then draws the pigment into the injection pan, ensuring it can store pigment and supply it to the marking mechanism. The marking mechanism then marks problematic road sections, enabling workers to quickly locate defects and avoid omissions due to insufficient light. By working in conjunction with a road tester, the marking device can provide real-time, prominent maintenance markings, preventing road maintenance personnel from missing sections during repairs. This also addresses the problem in the original equipment where light intensity changes over time, leading to less visible defects and missed defects.

[0016] Advantage 2: This utility model incorporates a marking mechanism. A servo motor drives a transmission linkage to rotate, which in turn pushes a mounting slider. The slider moves up and down along a guide frame, causing the pressure plate to slide downwards with the suction cotton. This allows the suction cotton to contact the road surface, and under pressure, the paint markings are printed onto the road surface. This prevents road maintenance personnel from missing sections due to insufficient light during inspections, facilitating subsequent maintenance of the affected section. Ultimately, the marking mechanism marks problematic road sections, enabling workers to quickly locate defective sections and preventing omissions due to insufficient light.

The power supply board 4 is built on the top of the road tester 3. The marking device 5 is installed at the left end of the road tester 3. The early warning device 6 is electrically connected to the outside of the marking device 5 and is fixed to the front end of the road tester 3. The monitoring sensor 7 is installed at the right end of the road tester 3.

[0025] Please see Figure 3 and Figure 4 This utility model provides an improved asphalt pavement temperature monitoring and early warning device. The marking device 5 includes an installation cylinder 51, an injection hole 52, a drive motor 53, a refining shaft 54, a pump 55, an injection plate 56, and a marking mechanism 57. The installation cylinder 51 is fixed to the left end of the installation base 1. The injection hole 52 is located at the top of the installation cylinder 51. The drive motor 53 is connected to the top of the installation cylinder 51. The drive motor 53 is connected to the top of the refining shaft 54 ​​via a coupling. The refining shaft 54 ​​is rotatably connected to the inside of the installation cylinder 51. The pump 55 is installed inside the installation cylinder 51. The injection plate 56 is assembled at the left end of the pump 55. The marking mechanism 57 is slidably connected to the inside of the injection plate 56.

[0026] In this embodiment, the installation cylinder 51 is equipped with a partition, the liquid pump 55 and the marking mechanism 57 are vertically arranged inside the installation cylinder 51, the overall structure of the liquid injection plate 56 is a hollow disc structure, and the inside of the liquid injection plate 56 is provided with square-shaped liquid injection holes.

[0027] Please see Figure 5 This utility model provides an improved asphalt pavement temperature monitoring and early warning device. The marking mechanism 57 includes a servo motor 571, a transmission link 572, a mounting slider 573, a guide frame 574, a pressure plate 575, and a suction cotton 576. The servo motor 571 is installed inside the mounting cylinder 51. The servo motor 571 is connected to the right end of the transmission link 572 by a coupling. The transmission link 572 is nested with the left end of the mounting slider 573. The mounting slider 573 is slidably connected to the right end of the guide frame 574. The guide frame 574 is located inside the left end of the mounting cylinder 51. The pressure plate 575 is fixed to the bottom of the mounting slider 573. The bottom of the pressure plate 575 is covered with suction cotton 576.

[0028] In this embodiment, the left end of the mounting slider 573 is provided with a groove that slides in cooperation with the inside of the guide frame 574, ensuring that the mounting slider 573 can slide vertically under the guidance of the right end of the guide frame 574. The internal size of the pressure plate 575 matches the internal size of the liquid injection plate 56, and the pressure plate 575 can be incorporated into the liquid injection plate 56, so that the suction cotton 576 provided below the pressure plate 575 can absorb the paint liquid. The suction cotton 576 is vertically arranged at the bottom of the pressure plate 575.

[0029] refer to Figures 1-5 In use, the towing component 2 is mounted at the rear end of the transport vehicle, allowing it to move horizontally along with the mounting base 1. This ensures that the road sensor 3 can move horizontally with the mounting base 1, facilitating the monitoring of the sensor 7 to detect road surface temperature and defects.

[0030] When a road defect is detected, the warning device 6 can send a warning signal to the cloud platform and the marking device, so that staff can view the defective road section through the cloud platform.

[0031] Meanwhile, the pigment and water are injected into the installation cylinder 51 through the injection hole 52 in advance. The drive motor 53 is started to drive the refining shaft 54 ​​to rotate, so that the pigment and water can be fully mixed inside the installation cylinder 51 to form pigment. The pump 55 is started to pump the pigment into the injection tray 56, so that the injection tray 56 can store pigment and ensure that the injection tray 56 can provide pigment to the marking mechanism 57.

[0032] Subsequently, the servo motor 571 drives the transmission linkage 572 to rotate, causing the linkage 572 to push the mounting slider 573. The mounting slider 573 slides up and down along the guide frame 574, thereby pushing the pressure plate 575 to slide downwards with the suction cotton 576. This allows the suction cotton 576 to come into contact with the road surface, and under pressure, the paint markings are printed on the road surface. This prevents road maintenance personnel from missing sections due to insufficient light during inspections, facilitating subsequent maintenance of the road section. Furthermore, the marking mechanism 57 marks problematic road sections, enabling workers to quickly locate defective sections and avoid omissions due to insufficient light.

[0033] This allows the marking device 5 to work in conjunction with the road tester 3, enabling the marking device 5 to mark conspicuous maintenance signs in real time. This prevents road maintenance personnel from missing road sections during subsequent maintenance, and solves the problem in the original equipment where the intensity of light changes over time, resulting in some defects not being conspicuous enough and defects being missed.
