DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0029] Example 1:

[0030] See also Figure 1-5 , a roller assembly for detecting the flatness of an asphalt concrete surface layer, comprising a main body 1, a detection mechanism and a quick connection mechanism, the detection mechanism comprising a roller 2, a sliding frame 3, a first spring 4, a detector 5, a data collector 6 and a balancing assembly, the roller 2 being mounted on the sliding frame 3 and being rotatably connected to the sliding frame 3, the sliding frame 3 being mounted inside the main body 1 and being slidably connected to the main body 1, the first spring 4 being mounted inside the main body 1 and the other end being fixedly connected to the sliding frame 3, the detector 5 being fixedly mounted on the main body 1, the data collector 6 being fixedly mounted on the main body 1, the balancing assembly comprising an outrigger 7, a balancing roller 8 and a shock absorber 9, the outrigger 7 being mounted on the main body 1 and being rotatably connected to the main body 1, the balancing roller 8 being mounted on the outrigger 7 and being rotatably connected to the outrigger 7, the shock absorber 9 being fixedly mounted on the main body 1, and its output end being rotatably connected to the outrigger 7.

[0031] In this embodiment, the detection mechanism includes a roller 2, a sliding frame 3, a first spring 4, a detector 5, a data collector 6 and a balancing component. When in use, after the main body 1 is connected to the driven vehicle, the main body 1 is placed on the road surface. Under the influence of gravity, the main body 1 descends and begins to compress the first spring 4, and the sliding frame 3 also enters the main body 1. The first protrusion 19 on the sliding frame 3 slides in the first limiting slide groove 18 in the main body 1. At this time, the first spring 4 reaches a balanced state due to the gravity of the main body 1. The sliding frame 3 in the figure is in a balanced state and the detector 5 installed on the main body 1 monitors the sliding frame 3. When the driving vehicle starts to run, the balancing roller 8 installed on the outrigger 7 begins to rotate as it contacts the ground, and the roller 2 inside the sliding frame 3 also rotates accordingly. When encountering a low-lying area, When the road surface is bumpy, the balancing roller 8 will rise and fall accordingly, causing the outrigger 7 to rise and fall accordingly. When the outrigger 7 rises and falls, the output end of the shock absorber 9, which is rotatably connected to the outrigger 7, slides in the compression groove 22 of the connecting plate 21, thereby applying force to the output end of the shock absorber 9 and starting to absorb vibration, reducing the impact of the road surface fluctuations on the balancing roller 8 and the outrigger 7, thereby ensuring the balance of the main body 1. When the roller 2 in the main body 1 encounters a pothole, it directly enters the pothole, and the sliding frame 3 also slides accordingly. The through rod 17 on the main body 1 slides in the through hole 20 of the sliding frame 3, and the detector 5 records the changes of the sliding frame 3 at this time, and transmits the data to the data collector 6. The data collector 6 summarizes the data received by multiple detectors 5 to obtain data on the flatness of the road surface.

[0032] In this embodiment, the quick connection mechanism includes a mounting plate 10, a mounting bolt 11, a fixing rod 12, a second spring 13 and a positioning assembly. When in use, the mounting plate 10 is placed on the driving vehicle, and then the mounting bolt 11 is used to fix the mounting plate 10 and the driving vehicle. After the mounting plate 10 is installed, the connecting groove 24 on the connecting plate 23 is aligned with the connecting groove 24 on the mounting plate 10, and the fixing rod 12 is placed in the connecting groove 24 to fix the connection between the mounting plate 10 and the connecting plate 23. At this time, the fixing block 25 at the bottom end of the fixing rod 12 is placed in the connecting groove 24, and the fixing rod 12 is slid to the two ends of the connecting groove 24. In the process, the sliding block 1 is pulled 6 slides on the fixing rod 12 and begins to compress the second spring 13. At this time, the sliding block 16 is placed on the connecting disk 23. After the connecting disk 23 contacts the positioning rod 15 installed inside the sliding block 16, the positioning rod 15 at this time begins to enter the sliding block 16 and compress the third spring 14 under the pressure of the second spring 13. During this process, the second protrusion 28 on the positioning rod 15 slides in the second limiting groove 27 inside the sliding block 16. When the fixing rod 12 moves to one end of the connecting groove 24, the positioning rod 15 contacts the positioning hole 26. When there is no obstruction from the connecting disk 23, the positioning rod 15 enters the positioning hole 26, thereby connecting and fixing the mounting plate 10 and the connecting disk 23.

[0033] Example 2:

[0034] To sum up, when in use, first quickly connect the main body 1 and the driving vehicle, then place the mounting plate 10 on the driving vehicle, and then use the mounting bolts 11 to fix the mounting plate 10 and the driving vehicle. After the mounting plate 10 is installed, align the connecting groove 24 on the connecting plate 23 with the connecting groove 24 on the mounting plate 10, and start to place the fixing rod 12 in the connecting groove 24, so that the connection between the mounting plate 10 and the connecting plate 23 is fixed. At this time, place the fixing block 25 at the bottom end of the fixing rod 12 into the connecting groove 24, slide the fixing rod 12 to both ends of the connecting groove 24, pull the sliding block 16 to slide on the fixing rod 12 in the process and start to compress the second spring 13. At this time, When the sliding block 16 is placed on the connecting plate 23, the connecting plate 23 contacts the positioning rod 15 installed inside the sliding block 16. At this time, the positioning rod 15 begins to enter the sliding block 16 and compress the third spring 14 under the pressure of the second spring 13. In this process, the second protrusion 28 on the positioning rod 15 slides in the second limiting slot 27 inside the sliding block 16. When the fixing rod 12 moves to one end of the connecting slot 24, the positioning rod 15 contacts the positioning hole 26. When there is no obstruction from the connecting plate 23, the positioning rod 15 enters the positioning hole 26, thereby fixing the connection between the mounting plate 10 and the connecting plate 23. When the main body 1 is connected to the driven vehicle, the main body 1 is placed On the road surface, affected by gravity, the main body 1 descends and begins to compress the first spring 4, and the sliding frame 3 also enters the main body 1. The first protrusion 19 on the sliding frame 3 slides in the first limiting slide groove 18 in the main body 1. At this time, the first spring 4 is subjected to the gravity of the main body 1 and reaches a balanced state. The sliding frame 3 in the figure is in a balanced state and the detector 5 installed on the main body 1 monitors the sliding frame 3. When the driving vehicle starts to run, the balancing roller 8 installed on the outrigger 7 begins to rotate as it contacts the ground, and the roller 2 inside the sliding frame 3 also rotates accordingly. When encountering a low and undulating road surface, the balancing roller 8 at this time will fluctuate accordingly, causing the outrigger 7 to fluctuate accordingly. When the outrigger 7 rises and falls, the output end of the shock absorber 9, which is rotatably connected to the outrigger 7, slides in the compression groove 22 of the connecting plate 21, thereby applying force to the output end of the shock absorber 9 and starting to reduce vibration, reducing the impact of road surface fluctuations on the balance roller 8 and the outrigger 7, thereby ensuring the balance of the main body 1. When the roller 2 in the main body 1 encounters a pothole, it directly enters the pothole, and the sliding frame 3 also slides accordingly. The through rod 17 on the main body 1 slides in the through hole 20 of the sliding frame 3, and the detector 5 records the changes in the sliding frame 3 at this time, and transmits the data to the data collector 6. The data collector 6 summarizes the data received by multiple detectors 5 to obtain data on the flatness of the road surface.

[0035] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded.
