Description

Technical Field

[0002] Asphalt pavement occupies a vital position in modern transportation infrastructure. It is widely used in highways, urban roads, airport runways and other places. Due to its good driving comfort, sufficient mechanical strength and durability, it can withstand repeated loads from vehicles.

[0003] The flatness of the road surface will also affect the comfort of passengers in the car. If the road surface is significantly uneven or irregular, the vehicle will experience bumps when driving, affecting the riding experience, and long-term bumps may also cause damage to vehicle components.

[0004] The method of testing asphalt pavement mainly relies on manual testing using simple tools, such as a three-meter ruler. The tester places the three-meter ruler on the road surface and evaluates the flatness of the road surface by measuring the gap between the ruler and the road surface. This method is simple to operate, but the efficiency is extremely low, and it can only detect local areas. The data is poorly representative and cannot be accurately tested through multiple methods.

[0050] A detection method for an asphalt pavement engineering detection device comprises the following steps:

[0051] S1. First, push the handlebar 4, cooperate with the moving part 2, the controller 3 and the remote control panel 5, so that the frame 1 can move forward, that is, the device body can move forward;

[0052] S2, cooperate with the rectangular plate 61, the slide bar 62 and the bottom plate 63, when the stepper motor 64 is started, the rotating shaft 65 rotates, thereby driving the cross 66 and the moving frame 67 to rotate synchronously, and the servo electric push rod 69 is started, so that its piston end enters the limit hole 610, so that multiple groups of rollers 68 alternately contact the ground, to avoid the wear and damage of a single roller 68, which needs to be replaced, and delay the overall detection progress efficiency. When encountering an uneven asphalt road surface, the slide bar 62 will move up and down on the inner side of the rectangular plate 61 (upward when encountering a protrusion, and downward when encountering a depression), so that the magnetic block 614 moves synchronously, cooperate with the N-shaped frame 611, the vertical plate 612 and the proximity sensor switch 613, so that the magnetic block 614 approaches or moves away from the proximity sensor switch 613 at different heights, so that the flatness of the asphalt road surface is judged by the controller 3 according to whether the corresponding proximity sensor switch 613 is started or the frequency of starting;

[0053] S3, when the frame 1 moves forward, the servo linear module 73 is started, so that the square plate 74 with the animation board 75 can move forward and backward, and when the slide bar 62 moves up and down, the clamping rod 71 and the brush 72 are driven to move up and down synchronously, so that the brush 72 will paint a wavy mark on the drawing board 75 on the square plate 74, and the flatness of the asphalt road surface can be observed with the naked eye in conjunction with the horizontal schematic line 76, thereby increasing the detection method and making the detection result more accurate (the higher the road surface flatness, the closer the wave crest and trough endpoints of the wavy mark are to the horizontal schematic line 76, and the wave crest and trough endpoints of the wavy mark are to the horizontal schematic line 76, and the wave shape is wavy);

[0054] S4. When the slide bar 62 moves up and down, it will drive the hinge sleeve 81 to move synchronously, so that the hinge seat 84 can move synchronously inside the slide rail 83 in cooperation with the hinge bar 82, so that the movement of the slide bar 62 is more stable, and the detection result is more accurate;

[0055] S5, when the servo hydraulic cylinder 85 is started, the push plate 86 synchronously pushes the hinge seat 84 to slide, so that when the flatness detection is not performed, multiple groups of slide bars 62 are lifted at the same time, and their bottoms are away from the ground, so as to better protect the parts;

[0056] S6. In combination with the rectangular cover 91, the rectangular cover 92, the through hole 93 and the laser smoothness meter 94, a detection method is added. The transmitter of the laser smoothness meter 94 can emit a laser beam to the road surface, and the receiver receives the reflected light. The distance between the road surface and the laser smoothness meter 94 is determined by calculating the time difference of the laser's round trip, so as to obtain the longitudinal elevation data of the road surface, so as to analyze the smoothness of the road surface. In combination with the side plate 96, the servo motor 97 is started to rotate the driving sprocket 98, and in combination with the transmission of the driven sprocket 99 and the transmission chain 910, multiple groups of conical covers 95 are rotated synchronously to avoid the accumulation of impurities inside the conical covers 95. At the same time, in combination with the baffle 911, the laser smoothness meter 94 can be better protected.

[0057] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
