DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-5 The present embodiment provides a technical solution: an intelligent 3D asphalt pavement paving and compaction precision control device that is easy to position, comprising a cross bar 1, a slide groove 4 is provided on the lower surface of the cross bar 1 along the center line, a rotating shaft 25 is provided inside the slide groove 4 for rotation, a bearing block 26 is installed on the outer circumferential surface of the rotating shaft 25, an outer body 27 is fixedly connected to the outer circumferential surface of the bearing block 26, an air inlet net 28 is provided on the outer side surface of the outer body 27, a fan 29 is installed at the center position of the lower surface of the outer body 27, an air duct 30 is connected to the inside of the fan 29, a compression head 31 is connected to the lower end of the air duct 30, and an air outlet 32 is installed on the lower surface of the compression head 31.

[0026] A right base 6 is provided in the vertical plane of the cross bar 1, i.e., the yz plane, along the positive direction of the x-axis. A screw hole 7 is provided at the edge of the circumferential surface of the front surface of the right base 6. A first right connecting rod 8 is connected to the center position of the rear surface of the right base 6. A first right joint 9 is rotatably provided at the end of the first right connecting rod 8. The lower surface of the first right joint 9 is rotatably connected to the second right connecting rod 10. The lower end of the second right connecting rod 10 is fixedly connected to the second right joint 11 at the center position of the lateral surface. A third right connecting rod 12 is installed at the end of the second right joint 11. A third right joint 14 is provided at the lower end of the third right connecting rod 12. A first fixed block 15 is welded to the lower surface of the third right joint 14.

[0027] A left base 5 is provided on the vertical plane of the crossbar 1, i.e., the yz plane, along the negative direction of the x-axis. A first left link 17 is connected to the center position of the rear surface of the left base 5. A first left joint 18 is rotatably provided at the end of the first left link 17. The lower surface of the first left joint 18 is rotatably connected to a second left link 19. A second left joint 20 is fixedly connected to the center position of the lateral surface of the lower end of the second left link 19. A third left link 21 is installed at the end of the second left joint 20. A third left joint 22 is provided at the lower end of the third left link 21. A second fixed block 24 is welded to the lower surface of the third left joint 22. Two robotic arms are set at the left and right ends of the equipment for combined use to adapt to more complex road sections and detect road bumps of different sizes.

[0028] The upper surface of the crossbar 1 is fixedly connected to a connecting column 3, the upper end of the connecting column 3 is connected to an air blowing platform plate 2, and a radar 16 is fixedly installed on the lower surface of the air blowing platform plate 2 near the front edge. Installing a laser radar to scan potholes on the paving equipment can quickly scan out the depth and shape of the ground depression. The data is transmitted to the control system in real time, and the amount of asphalt that needs to be filled is automatically calculated, which is convenient for construction workers to repeatedly compact the potholes.

[0029] An infrared transmitter 13 is installed on the front surface of the first fixed block 15, and an infrared receiver 23 is installed on the front surface of the second fixed block 24. An infrared detection device is installed on the equipment, which can scan the ground at any time. The data is transmitted to the system to adjust the discharge thickness, speed up the construction progress, and no rework is required later.

[0030] The infrared transmitter 13 and the infrared receiver 23 detect the range of ground protrusions through uninterrupted transmission and reception. By adding an infrared detection device to the equipment, the ground protrusions can be detected in real time. Regardless of the construction environment day or night, the construction team can carry out construction without worrying about errors.

[0031] Radar 16 emits a short pulse laser beam to the road surface, and calculates the distance by combining the time difference between emission and reception with the speed of light. Using laser pulse ranging, the depth of potholes on the ground can be accurately calculated. The data is transmitted to the control system in real time, and the gaps are automatically filled when paving asphalt, and the roller adjusts the number of rolling times synchronously.

[0032] The infrared transmitter 13 and the infrared receiver 23 are manually calibrated initially. Adding an initial manual calibration step to the infrared device and manually adjusting the baseline before starting work can offset errors caused by equipment jitter or temperature differences. When constructing on complex terrain, the data is more reliable and the trouble of repeated debugging is eliminated.

[0033] The infrared transmitter 13 and the infrared receiver 23 are respectively installed on the same horizontal line at the left and right ends of the asphalt paving and compacting equipment. The infrared device is installed at the same height on the left and right sides of the equipment to scan the ground synchronously on the left and right sides. The blind spots of the shoulder can be evenly covered and detected to ensure that the paved road surface is flush on both sides.

[0034] The horizontal field of view of radar 16 is 120 degrees and the scanning frequency is 10Hz. The radar is set to a 120-degree wide angle plus 10 scans per second, which is equivalent to fast data refresh. The ground height can be updated immediately when the car is slightly bumpy. Regardless of any road conditions, work efficiency can be guaranteed.

[0035] In summary, the present invention adds a compressed air cleaning structure to the intelligent paving equipment. The high-pressure airflow can thoroughly clean the debris and accumulated water in the pit, and the dust in the corners and gaps can also be cleaned, which is better than manual cleaning. It can also quickly dry the working surface to avoid moisture residue on the asphalt contact surface, so that the new and old asphalt are bonded faster. The entire cleaning process does not require stopping to change tools. The equipment can pave while blowing, saving working time. The working effect is better on continuous potholes and road sections, ensuring the durability of the repaired road surface while improving the construction efficiency of the team; a flexible twisting robotic arm is installed in the paving equipment to control the infrared calibration structure. The six-degree-of-freedom robotic arm can adjust the angle in all directions. When constructing in complex terrain, it can achieve the same automatic leveling effect as the human eye, and the calibration space is wider and in place. Secondly, the infrared scans the height difference of the ground in real time, and the robotic arm immediately fine-tunes the paving thickness to reduce errors. In addition, the construction process does not require manual repeated measurement and adjustment, saving construction workers' working time, improving efficiency and not easy to rework.

[0036] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs a structure and embodiment similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
