Under normal circumstances, the first motor 18 drives the mounting sleeve 20 to rotate by driving the prism 19 to rotate, so that the mounting sleeve 20 drives the fan gear 9 and the incomplete gear 8 to rotate.

[0040] In one case of this embodiment, the counterweight rolling structure 14 includes two groups of guide rods 21 fixedly connected to the frame 1, the two groups of guide rods 21 are arranged in parallel, and the two groups of guide rods 21 are slidably connected to a group of hollow frames 22, a counterweight bucket 23 is fixedly installed on the top of the hollow frame 22, and a slope 24 is provided on the side of the counterweight bucket 23 facing the displacement pressure lifting structure 15, the hollow frame 22 is slidably connected to a wheel frame 25, and the wheel frame 25 is rotatably connected to a pressure wheel 26, the wheel frame 25 is fixedly connected to a vertical plate 27 slidably connected to the frame 11, the wheel frame 25 is connected to the displacement pressure lifting structure 15, the relative sliding direction of the wheel frame 25 and the hollow frame 22 is horizontal, and the relative sliding direction of the vertical plate 27 and the frame 11 is vertical. The counterweight bucket 23 is used to load the counterweight block to adjust the pressure of the hollow frame 22 on the wheel frame 25, thereby adjusting the pressure applied by the pressure wheel 26 on the pavement sample block 4. When the frame 11 drives the vertical plate 27 to move laterally, the vertical plate 27 drives the wheel frame 25 to move, and the wheel frame 25 and the hollow frame 22 move laterally relative to each other, so that the wheel frame 25 drives the pressure wheel 26 to move.

[0041] In one case of this embodiment, the displacement pressure-lifting structure 15 includes a guide frame 28 slidably connected to the wheel frame 25, the direction in which the wheel frame 25 and the guide frame 28 slide relative to each other is vertical, the guide frame 28 is fixedly connected to two groups of elastic telescopic rods 29, the movable end of the elastic telescopic rod 29 is fixedly connected to a ball 30, the guide frame 28 is slidably connected to a card frame 31 movably connected to the ball 30, the card frame 31 is fixedly connected to two groups of trapezoidal bars 32, the card frame 31 is fixedly connected to an extrusion shaft 33, and the frame 1 is fixedly connected to a suspension 34, the suspension 34 is fixedly connected with a first extrusion block 35, and the suspension 34 is fixedly connected with a second extrusion block 36. The first extrusion block 35 and the second extrusion block 36 have the same structure. The notch of the first extrusion block 35 is directly opposite to the notch of the second extrusion block 36 and is arranged in the opposite direction. The notch of the first extrusion block 35 and the notch of the second extrusion block 36 are both oblique bucket-shaped structures. The notch of the first extrusion block 35 and the notch of the second extrusion block 36 are both used to press the extrusion shaft 33.

As the extrusion shaft 33 moves into the notch of the first extrusion block 35, the notch of the first extrusion block 35 presses the extrusion shaft 33, so that the extrusion shaft 33 drives the bracket 31 to disengage from the existing clamped spheres 30 and move toward another group of spheres 30. The bracket 31 drives the trapezoidal bar 32 to disengage from the counterweight bucket 23, so that under the action of gravity, the counterweight bucket 23 descends, the counterweight bucket 23 drives the hollow frame 22 to descend, and the hollow frame 22 drives the wheel frame 25 to descend, so that the wheel frame 25 drives the pressing wheel 26 to descend. When the extrusion shaft 33 moves from the first extrusion block 35 to the second extrusion block 36, the pressing wheel 26 continues to press on the top of the road surface block 4, so that the pressing wheel 26 performs a linear rolling operation on the road surface block 4.

[0043] In one aspect of this embodiment, a weighing platform 40 is fixed to the arch frame 5 . The weighing platform 40 is used to measure the pressure applied by the pressure wheel 26 .

Under the top pressure of the elastic telescopic rod 29 on the sphere 30, the bracket 31 is separated from the originally clamped sphere 30 and clamped with another group of spheres 30. At this time, the belt of the bracket 31 Under the action, the trapezoidal bar 32 and the inclined surface 24 squeeze each other, thereby lifting the counterweight bucket 23, and the counterweight bucket 23 drives the hollow frame 22 to rise, and the hollow frame 22 drives the wheel frame 25 to rise, so that the wheel frame 25 drives the pressure wheel 26 to rise, and the wheel frame 25 and the guide frame 28 slide vertically relative to each other, and the vertical plate 27 and the frame 11 slide vertically relative to each other. At this time, the pressure wheel 26 and the road surface block 4 move away from each other. In the process of the extrusion shaft 33 moving from the second extrusion block 36 to the first extrusion block 35, the pressure wheel 26 and the road surface block 4 continue to separate. As the extrusion shaft 33 moves into the notch of the first extrusion block 35, the notch of the first extrusion block 35 presses the extrusion shaft 33, so that the extrusion shaft 33 drives the bracket 31 to break away from the existing Some of the clamped spheres 30 move toward another group of spheres 30, and the clamping frame 31 drives the trapezoidal bar 32 to separate from the counterweight bucket 23, so that under the action of gravity, the counterweight bucket 23 descends, the counterweight bucket 23 drives the hollow frame 22 to descend, and the hollow frame 22 drives the wheel frame 25 to descend, so that the wheel frame 25 drives the pressure wheel 26 to descend. In the process of the extrusion shaft 33 moving from the first extrusion block 35 to the second extrusion block 36, the pressure wheel 26 continues to press on the top of the pavement sample block 4, so that the pressure wheel 26 performs a linear rolling operation on the pavement sample block 4. After the counterweight rolling structure 14 stops rolling the pavement sample block 4, the scanning structure 16 scans the pavement sample block 4 again to obtain the deformation data of the rolled pavement sample block 4.
