The depth of the crack is measured through the detection rope 60 and the detection cone 62, when the detection cone 62 touches the ground, the value of the tension sensor is reduced, and the release distance of the detection rope 60 is controlled according to the change of the value of the sensor, so that the depth of the crack is obtained; the width of the slit is obtained by the distance the slide bar 610 and the roller 611 move within the rotating frame 65. In the moving process of the frame 1, if the crack is curved as shown in fig. 9, the angle of the rotating frame 65 relative to the hollow tube 61 needs to be adjusted in time, otherwise, the phenomenon of the left side of fig. 9 occurs, the calculated crack width is larger than the actual width, because the rotating disk 64 contacts one side of the crack, when the crack turns, the contact position between the rotating disk 64 and the crack changes, at the moment, the contact position between the upper hollow tube 61 and the lower hollow tube 61 due to the change of the direction of the acting force changes, so that the electric signal intensity is changed, the driving motor 68 on the bottom rotating frame 65 is controlled according to different electric signal intensities, so that the rotating frame 65 is controlled to rotate relative to the hollow tube 61, the width measuring assembly is adjusted from the left side state of fig. 9 to the right side state, and the accuracy of crack width calculation is ensured. Because the idle pipe can change in position relative to the first horizontal frame 52 when the crack is bent, in order to provide the horizontal adjustment allowance of the crack detection mechanism, the first horizontal frame 52 and the horizontal sliding block 55 are arranged, the crack detection mechanism 6 is installed, and the frame 1 is ensured to accurately measure the width and the depth of the crack under the condition of not changing the moving direction. The conveying quantity of the asphalt concrete needs to be slightly larger than the required quantity of the crack point positions, so that the compression roller 72 is convenient to compress the asphalt concrete, the redundant asphalt concrete is recovered through the cleaning shovel 738 and the receiving hopper 739, and the flatness of the repaired part is ensured.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention. Any reference sign in a claim should not be construed as limiting the claim concerned.
