The two sets of sprockets 4 are connected by a chain 5, so the first motor 3 drives the two sets of sprockets 4 to rotate at the same time, the lower end of the sprocket 4 is connected to the first threaded rod 6, the rotation of the sprocket 4 drives the first threaded rod 6 to rotate, the lower end of the first threaded rod 6 is threadedly connected to the first threaded sleeve 7, the lower end of the first threaded sleeve 7 is fixedly connected to the sliding block 8, and a telescopic rod 9 is connected between the workbench 1 and the sliding block 8, the telescopic rod 9 limits the rotation of the sliding block 8, so the telescopic rod 9 plays a limiting role on the first threaded sleeve 7, when the first threaded rod 6 rotates, it drives the first threaded sleeve 7 to rise and fall, and at the same time makes the sliding block 8 move vertically along the support frame 2. There are three groups of support rods 10 equidistantly connected on 8, and the middle ends of the support rods 10 are rotatably connected to the connecting rods 11, and the connecting rods 11 are rotatably connected to the fixed blocks 12, and the fixed blocks 12 are fixedly connected to the support frame 2. Therefore, when the sliding block 8 descends, the angle between the sliding block 8 and the support rods 10 becomes larger, and the angle between the support rods 10 and the connecting rods 11 increases. Therefore, the three groups of support rods 10 improve the stability of the support frame 2, and the support frame 2 and the support rods 10 support the workbench 1, which can enhance the stability of the device and prevent the device from tipping over during the detection process, affecting the measurement accuracy of the device, and at the same time play a protective role for the device.

Since the upper right end of the pressure plate 16 is fixedly connected with a vertical rod 17, and the vertical rod 17 passes through the workbench 1, the vertical rod 17 prevents the pressure plate 16 from rotating, and plays a limiting role on the second threaded sleeve 15, preventing the second threaded sleeve 15 from rotating. Therefore, when the second threaded rod 14 rotates, it drives the second threaded sleeve 15 to rise and fall, and can drive the pressure plate 16 and the vertical rod 17 to rise and fall. A scale line 18 is provided on the upper end of the vertical rod 17. When the second motor 13 drives the pressure plate 16 to press down for measurement, the road surface compaction height can be known by the change of the scale line 18 on the vertical rod 17, thereby improving the convenience of the device and making the device usable multiple times. It is also convenient to intuitively understand the road surface compaction height for easy recording.

[0031] Working principle: When using the road surface compaction height detection device for highway construction, the detection device is placed on the road surface, and the first motor 3 is used to drive the sprocket 4 to rotate. The sprocket 4 is provided with two groups, and the two groups of sprockets 4 are connected by a chain 5. Therefore, the first motor 3 can drive the two groups of sprockets 4 to rotate at the same time. The rotation of the two groups of sprockets 4 drives the first threaded rod 6 at the lower end to rotate. The lower end of the first threaded rod 6 is connected to the first threaded sleeve 7, and the lower end of the first threaded sleeve 7 is connected to the sliding block 8. The workbench 1 and the sliding block 8 are connected by a telescopic rod 9. The telescopic rod 9 plays a limiting role on the first threaded sleeve 7. Therefore, the rotation of the first threaded rod 6 drives the first threaded sleeve 7 to rise and fall, and at the same time drives the sliding block 8 to rise and fall. The sliding block 8 is rotatably connected to the support rod 10, and the middle end of the support rod 10 is rotatably connected to the connecting rod 11, and the connecting rod 11 is rotatably connected to the fixed block 12. Therefore, when the sliding block 8 descends, the angle between the support rod 10 and the support frame 2 increases. The second threaded rod 14 is driven by the second motor 13 to rotate, and the lower end of the second threaded rod 14 is threadedly connected to the second threaded sleeve 15, and the lower end of the second threaded sleeve 15 is connected to the pressure plate 16, and the upper end of the pressure plate 16 is fixedly connected to the vertical rod 17. The vertical rod 17 passes through the workbench 1 and is slidably connected to the workbench 1. Therefore, the vertical rod 17 limits the rotation of the pressure plate 16 and also limits the rotation of the second threaded sleeve 15, which plays a limiting role on the second threaded sleeve 15. Therefore, when the second threaded rod 14 rotates, the second threaded sleeve 15 can be driven to rise and fall, and the pressure plate 16 can be driven to rise and fall, and the road surface compaction height can be detected. The upper end of the vertical rod 17 is provided with a scale line 18, and the specific value of the road surface compaction height can be determined by the change of the scale line 18.
