Description

Technical Field

[0001] The utility model belongs to the technical field of intelligent monitoring of asphalt pavement paving, and in particular relates to a multi-directional intelligent monitoring system for asphalt pavement paving temperature. Background Art

[0002] During asphalt pavement construction, temperature control is a critical factor in ensuring pavement quality and performance. Temperature fluctuations during the spreading, compaction, and curing of the asphalt mixture can affect the viscosity and bonding properties of the asphalt, which in turn impacts the pavement's compactness, durability, and overall performance. During the asphalt pavement construction process, paver spreaders and rollers are deployed. Pavers typically have a hopper that accommodates dump trucks.

[0003] In the prior art, temperature monitoring is usually involved in the process of paving asphalt pavement. The conventional practice is for workers to hold a thermometer to monitor the mixture entering the receiving hopper or discharged by the paver. This is time-consuming and labor-intensive, and has low efficiency and large errors. In addition, there is also a method of using a temperature monitoring and early warning device, such as the patent number: 202221429025.X; the patent name is: A paving temperature monitoring and early warning device for road engineering construction. This temperature monitoring and early warning device is independently set and also requires corresponding staff to use it. It is not convenient to move, data collection is not timely, and it cannot ensure multi-directional rapid monitoring, resulting in low monitoring efficiency. Utility Model Content

DETAILED DESCRIPTION

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0032] See also Figure 1 , the multi-directional intelligent monitoring system for asphalt pavement paving temperature provided by the present invention is now described. The multi-directional intelligent monitoring system for asphalt pavement paving temperature includes a first temperature monitoring unit 1, a second temperature monitoring unit 7 and a control unit. The first temperature monitoring unit 1 is arranged on the paver 4, and has a plurality of first temperature sensing parts that can be extended into the receiving hopper of the paver 4. Each first temperature sensing part can monitor the temperature of the mixture entering the receiving hopper of the paver 4 in real time. The second temperature monitoring unit 7 is arranged on the roller 5, and has a plurality of second temperature sensing parts, and each second temperature sensing part can monitor the temperature of the asphalt pavement under the roller 5. The control unit is wirelessly connected to the first temperature monitoring unit 1 and the second temperature monitoring unit 7, and can obtain temperature parameters in real time to adjust the working parameters of the paver 4 and the roller 5.

[0033] Compared with the prior art, the multi-faceted intelligent monitoring system for asphalt pavement paving temperature provided by this embodiment has a first temperature monitoring unit 1 provided on the paver 4, and each first temperature sensing portion located in the receiving hopper can ensure real-time monitoring of the temperature of the mixture poured into the receiving hopper by the dump truck. At the same time, when the roller 5 is working, the temperature of the mixture derived from the paver 4 can also be monitored in real time through each second temperature sensing portion. The data is then analyzed by the control unit to ensure that the working parameters of the paver 4 and the roller 5 are adjusted to ensure the paving effect of the road surface. This monitoring system can ensure real-time monitoring of the temperature of the mixture, can ensure timely and rapid data collection, and by setting up multiple temperature collection points, can further ensure the accuracy of temperature collection, and does not require the configuration of additional staff, saving time and effort, high monitoring efficiency, and strong practicality.

[0034] It should be noted that the control unit may include a remote monitoring center 6 and a wireless receiving module 3. This technology is conventional and will not be described in detail here. Regarding the control unit's adjustment of the paver 4 and roller 5, the control unit can analyze and process temperature parameters to set operating parameters such as the speed of the paver 4, the distance between rollers 5, and the travel speed of the roller 5. This can then be implemented by on-site staff.

[0035] In some embodiments, the first temperature monitoring unit 1 may be configured as follows: Figure 2 The structure shown. Figure 2The first temperature monitoring unit 1 includes multiple first temperature monitoring assemblies, each spaced apart along the width of the paver 4's receiving hopper. Each first temperature monitoring assembly comprises a fixed housing 11, guide rods 12, a movable cylinder 13, a first temperature sensor 14, and a telescopic structure 15. The fixed housing 11 is mounted on the paver 4's receiving hopper and has a receiving cavity. Two guide rods 12 are provided, spaced apart along the width of the paver 4's receiving hopper, and each guide rod 12 is positioned in the direction of travel of the paver 4. The movable cylinder 13 is positioned within the receiving cavity. One end of the movable cylinder 13 is slidably connected to the two guide rods 12, and the other end can extend through a through-hole provided in the fixed housing 11. The movable cylinder 13 has a cylindrical cavity with one end open, the opening of which is located away from the paver 4's receiving hopper. The first temperature sensor 14 is positioned within the cylindrical cavity and is electrically connected to the wireless transmitter module 2 disposed within the fixed housing 11. The first temperature sensor 14 is combined with the movable cylinder 13 to form a first temperature sensing portion. The telescopic structure 15 is fixed in the fixed box 11 and connected to the movable cylinder 13 to drive the guide rod 12 to move.

[0036] First, multiple first temperature monitoring components can realize multi-point and multi-directional temperature monitoring, ensuring the temperature monitoring accuracy and temperature monitoring effect.

[0037] The movable cylinder 13 needs to carry the first temperature sensor 14 into the receiving hopper and come into contact with the mixed material, which will inevitably cause sticky substances such as asphalt to adhere to the outer wall of the movable cylinder 13. Long-term accumulation will affect the temperature monitoring effect. Therefore, the movable cylinder 13 is driven by the telescopic structure 15 to move. During the process of the movable cylinder 13 being stored in the fixed box 11, the holes in the fixed box 11 will scrape off the sticky substances attached to the outer wall of the movable cylinder 13, thereby ensuring that the outer wall of the movable cylinder 13 is relatively clean and the temperature monitoring effect is guaranteed during long-term use.

[0038] The arrangement of the two guide rods 12 can ensure the sliding stability of the movable cylinder 13. The wireless transmitting module 2 can form a wireless connection with the control unit. Specifically, the wireless transmitting module 2 needs to be equipped with a power supply. This technology is existing technology and will not be described in detail here.

[0039] In addition, the movable cylinder 13 is retracted into the fixed box 11 by the telescopic structure 15, which can also protect the movable cylinder 13 and the first temperature sensor 14. Two telescopic structures 15 can be provided, and the two telescopic structures 15 correspond to the two guide rods 12 respectively.

[0040] In some embodiments, the fixing box 11 may be Figure 2 See the structure shown. Figure 2 The receiving hopper of the paver 4 has a vertical side wall for the fixed box 11 to be fixedly connected.

[0041] The fixing box 11 is located outside the receiving hopper. A through hole corresponding to the through hole is provided on the vertical side wall.

[0042] This structure can prevent the mixed material entering the hopper from adhering to the fixed box 11, ensuring the cleanliness of the fixed box 11, and also prevent the fixed box 11 from affecting the material receiving effect of the hopper. In addition, the through holes provided in the vertical side walls of the hopper ensure that when the movable cylinder 13 is moved out, the material adhering to the outer wall of the movable cylinder 13 is scraped off, thereby ensuring that the scraped material remains in the hopper.

[0043] In some embodiments, the movable cylinder 13 may be Figure 2 The structure shown. Figure 2 One end of the movable cylinder 13 is provided with a sliding plate that is slidably connected to the two guide rods 12, and the sliding plate is provided with two sliding holes through which the two guide rods 12 pass.

[0044] The telescopic structure 15 is connected to the sliding plate.

[0045] The provision of the sliding plate can ensure that the movable cylinder 13 is conveniently fixedly connected to the two guide rods 12, and also facilitates the fixed connection between the movable cylinder 13 and the telescopic structure 15, with a simple structure and strong practicality.

[0046] In some embodiments, the telescopic structure 15 may be configured as follows: Figure 2 The structure shown. Figure 2 The telescopic structure 15 is an electric push rod, which has small size, high precision, easy control, and convenient installation.

[0047] In some embodiments, the movable cylinder 13 may be Figure 2 The structure shown. Figure 2 The movable cylinder 13 is made of heat-conducting metal material to ensure that the temperature is quickly transferred to the first temperature sensor 14 after contacting the mixture. The monitoring end of the first temperature sensor 14 can be close to the inner wall of the cylinder cavity.

[0048] Specifically, the movable cylinder 13 can be made of copper, which has good thermal conductivity.

[0049] In some embodiments, the first temperature sensor 14 may be a Figure 2 The structure shown. Figure 2 There are multiple first temperature sensors 14, and each first temperature sensor 14 is evenly distributed in the cylinder cavity. The multiple first temperature sensors 14 can further ensure the accuracy of temperature monitoring of each mobile cylinder 13 and ensure the temperature monitoring effect.

[0050] In some embodiments, the second temperature monitoring unit 7 may be configured as follows: Figure 3 See the structure shown. Figure 3 The second temperature monitoring unit 7 includes a plurality of second temperature monitoring assemblies, each of which is arranged in a horizontal annular pattern outside the roller at the front of the roller 5. Each second temperature monitoring assembly includes a telescopic rod 71 and a second temperature sensor 72. The telescopic rod 71 has a telescopic end that can move in the vertical direction. The second temperature sensor 72 is fixed to the telescopic end and is electrically connected to a wireless transmitter provided on the roller 5. The second temperature sensor 72 is a second temperature sensing unit.

[0051] Each second temperature monitoring component can realize multi-point and multi-directional temperature monitoring, ensuring the temperature monitoring accuracy and temperature monitoring effect.

[0052] The telescopic rod 71 may be an electric telescopic rod 71 , and the telescopic end may be adjusted to ensure that the distance from the second temperature sensor 72 to the bottom surface is adjusted, thereby further ensuring the temperature monitoring effect.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
