the hardness detection mechanism comprises a pressure cone 5, a hardness tester 6, a displacement sensor 7 and a hydraulic cylinder 8, wherein the pressure cone 5, the hardness tester 6 and the displacement sensor 7 are arranged on the sliding plate 3, the hydraulic cylinder 8 is arranged on the detection vehicle 1, the hardness tester 6 is fixed on the pressure cone 5, the lower end of a piston rod of the hydraulic cylinder 8 is provided with a bearing plate 9, the lower surface of the bearing plate 9 is abutted against the upper end of the pressure cone 5, the lower end of the pressure cone 5 penetrates through a hardness detection through hole 10 on the detection vehicle 1, and the displacement sensor;
the distance detector 4, the control system of the hydraulic cylinder 8, the hardness meter 6 and the displacement sensor 7 are all electrically connected with the control host 2.
It should be noted that, the distance detector 4 detects the distance between the detection probe and the road surface, and after the detection of one measurement point is finished, the distance detector 4 is moved to the left or right by the sliding plate 3, so that the detection of the next measurement point can be performed. After the detection of one detection line is completed (the detection line is a set of a plurality of measurement points when the slide board 3 moves from left to right or from right to left), the detection vehicle 1 is moved forward so that the detection of the next detection line can be performed. After the detected distance information is calculated by the control host 2, the dot matrix of the highway pavement can be obtained, so that the convex or concave position and the depth of the highway pavement can be calculated, and the simulated three-dimensional map of the highway pavement can be seen.
The hydraulic cylinder 8 applies force to the pressure cone 5 through the piston rod, the pressure cone 5 moves downwards, and when the lower end of the pressure cone 5 is in contact with the road surface, the hardness detection mechanism starts to detect the hardness of the road surface. The hardness tester 6 monitors the pressure applied by the hydraulic cylinder 8 in real time, and when the pressure reaches the hardness standard of the road surface, the next measuring point can be detected. After the detection of one detection line is completed, the detection vehicle 1 is moved forward to perform the detection of the next detection line. When the applied pressure breaks the road surface, the lower end of the pressure cone 5 is inserted into the ground. At the moment, the reading of the hardness tester 6 is suddenly reduced, and meanwhile, the control host 2 calculates the flatness information of the measuring point and the downward movement amount of the pressure bearing plate 9 measured by the displacement sensor 7 according to the flatness detection mechanism (the downward movement amount of the pressure bearing plate 9 is equal to that of the pressure cone 5, the downward movement amount exceeds a set value, namely the pressure cone 5 is considered to be inserted into the road surface to damage the road surface, when the road surface is convex or concave or flat, the deviation of the downward movement amount error of the pressure cone 5 can be corrected through the flatness information obtained through calculation), so that the fact that the road surface is damaged is determined, and the hardness standard that the measuring point does not reach the road surface is obtained.
During actual detection, the hardness measuring points are far less than the flatness measuring points, so that the operation or the closing of the hardness detecting mechanism is controlled by controlling the opening and the closing of the hydraulic cylinder 8.
By arranging the sliding plate 3, the flatness detection and the hardness detection of the measuring points in the width direction of the road pavement can be completed without moving the detection vehicle 1, so that the detection is convenient and efficient.
