Drive the second hydraulic cylinder 14 to move the insert plate 6. The insert plate 6 is inserted through the gap between the curbstone and the ground. As the insert plate 6 is inserted, it lifts the curbstone. After the curbstone is lifted, drive the first hydraulic cylinder 4 to raise the U-shaped frame 5. The traction device is connected to the traction frame 10. The mounting frame 7 and the traveling wheels 8 support the device. The traction device applies a pulling force to the device, driving the device to move and realize the traction of the curbstone.
[0026] Please see Figure 3 , Figure 4 and Figure 5 The mounting groove 13 is equipped with a slider 15, which is fixedly connected to the U-shaped frame 5. The upper end of the insert plate 6 is equipped with a sliding groove 16. The slider 15 is correspondingly set with the sliding groove 16, and the slider 15 is slidably connected to the insert plate 6.

The vibration damping plate 21 falls and contacts the ground, fixing the device and preventing it from sliding.
[0029] Working principle: The U-shaped frame 5 is placed on top of the curbstone. The first hydraulic cylinder 4 is driven to lower the U-shaped frame 5, and the insert plate 6 falls to contact the ground.
