[0024] A connecting mounting cylinder 11 is fixedly installed on the outer wall of one end of the sliding adjustment rod 10. A measuring component is provided on one side of the connecting mounting cylinder 11 and the fixed mounting cylinder 7. The two measuring components are configured as component one and component two. Component one is connected to the fixed mounting cylinder 7 and is used to measure the road surface height before the asphalt mixture is paved. Component two is connected to the connecting mounting cylinder 11 and is used to measure the road surface height after the asphalt mixture is paved. The measurement value of component one minus the measurement value of component two is the paving thickness of the asphalt mixture.

[0025] Component 1 and Component 2 are set with a horizontal spacing, and the size of the horizontal spacing changes according to the length of the asphalt paving machine; assuming that the distance between Component 1 and Component 2 is set to ten meters, the paving speed of the asphalt mixture is one meter per minute, and the time difference between the measurement values ​​of Component 1 and Component 2 at the same point is ten minutes; for example, the instantaneous measurement value of Point A by Component 2 is twelve centimeters, and Component 1 measured Point A ten minutes ago and the measurement value was two centimeters, then the paving thickness of the asphalt mixture at Point A is ten centimeters.

[0026] The measuring assembly includes a guide connecting frame 12 and a measuring connecting rod 13. A linear bearing is sleeved on the middle part of the outer wall of the measuring connecting rod 13. The linear bearing is fixedly installed inside the guide connecting frame 12, and a limit clamp 17 is provided at the top end of the linear bearing. The limit clamp 17 is fixedly sleeved on the outside of the measuring connecting rod 13 through a fixing pin.

[0027] The bottom end of the measuring connecting rod 13 passes through the guide connecting frame 12 and extends downward. The outside of its extended end is sleeved with a support spring 14. The bottom end of the guide connecting frame 12 is provided with a positioning groove, and the top end of the support spring 14 is clamped inside the positioning groove; and a limited connecting seat 15 is fixedly installed at the bottom of the extended end of the measuring connecting rod 13, and a measuring roller 16 is rotatably installed on one side of the limited connecting seat 15.

[0028] The top of the measuring connecting rod 13 is fixedly installed with a connecting cartridge 18 through a fixing pin, the top of the connecting cartridge 18 is fixedly connected to a fixed connecting arm 19, the bottom of one end of the fixed connecting arm 19 is fixedly connected to a sliding protective sleeve 20, and the inner wall of the top of the sliding protective sleeve 20 is fixedly installed with an infrared reflective sheet 21.

[0029] A positioning mounting cylinder 22 is slidably mounted inside the sliding protection sleeve 20, and an infrared rangefinder 23 is fixedly mounted on the inner wall of the bottom end of the positioning mounting cylinder 22. The infrared rangefinder 23 is used to measure the distance of the infrared reflective sheet 21; Figure 1 As shown, the infrared rangefinders 23 of component one and component two are at the same height, and the infrared reflective sheet 21 is also at the same height when not measuring.

[0030] A counterweight box 8 is fixedly installed on the top of the end of the fixed installation tube 7 away from component 2, and a counterweight block 9 is fixedly installed inside the counterweight box 8. When the distance between component 1 and component 2 is large, the stability of the overall device is improved.

[0031] A lifting connecting frame 6 is fixedly installed on one end of the fixed installation cylinder 7 close to component 2, and a limiting slide arm 5 is fixedly connected to one side of the lifting connecting frame 6. One end of the limiting slide arm 5 is slidably engaged with the limiting slide rail 4, and one side of the limiting slide rail 4 is fixedly connected to the installation connecting frame 1. A cylinder fixing frame 2 is fixedly installed on the top of one side of the installation connecting frame 1, and a lifting cylinder 3 is fixedly installed inside the cylinder fixing frame 2. The telescopic end of the lifting cylinder 3 is fixedly installed on the top of the lifting connecting frame 6, and the installation connecting frame 1 is connected to the asphalt paving machinery.

[0032] Working principle:

[0033] Please refer to Figures 1 to 3 , assemble the device as shown in the figure;

[0034] The device is connected to the asphalt paving machine by installing the connecting frame 1, and then the asphalt paving machine is moved to the specified position. The lifting cylinder 3 is then started, and the lifting cylinder 3 drives the entire device to descend through the lifting connecting frame 6, so that the measuring roller 16 of the measuring component contacts the ground, and then the asphalt mixture is started to be paved. The infrared rangefinder 23 and the infrared reflective sheet 21 of component one start working. During the asphalt mixture paving process, the measurement data of the base road surface is continuously recorded; for example, the initial recording point of component one is A, and the time when the measuring roller 16 of component two moves to point A is recorded synchronously. The measurement data of the asphalt paving material pavement is recorded from the time component two arrives at point A. At the same point, the data recorded by component two is subtracted from the data recorded by component one to obtain the thickness of the asphalt paving material at that point.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
