[0039] like Figure 1 to Figure 7 As shown, the moving wheel 102 is a universal wheel.

[0040] When in use, first adjust the lifting screw 105 to lift the lifting slide column 101 to adjust the height of the moving wheel 102, and synchronously adjust the height of the push rod 127 and the brake rod 125 through the lifting synchronization plate 103 to make the height of the entire device adapt to the height of the curb, and adjust the adjusting screw 110 to control the lifting of the threaded lifting cylinder 109. During the lifting process of the threaded lifting cylinder 109, the adjusting swing rod 110 is driven to swing. When the threaded lifting cylinder 109 rises, the angle between the adjusting swing rods 110 on both sides becomes smaller. At this time, the distance between a pair of alignment clamps 111 becomes smaller. By adjusting the distance between a pair of alignment clamps 111 to meet the needs of curbs of different thicknesses, before paving begins, first clamp part of the curb in the alignment clamp 111, and fix this part of the curb at the position to be laid, and after the subsequent curb is roughly arranged on the completed curb, the moving wheel 102 rotates, and the device moves to the paved curb and behind it The distance between the adjacent curbstones is shortened until the distance between the alignment clamps 111 is clamped at the contact position between the two adjacent curbstones. At this time, the curbstone behind is clamped in the alignment clamps 111 together with the previous curbstone and the alignment is completed. This step is repeated until all the curbstones are aligned. During the movement of the device, if the collision touch plate 114 touches an obstacle, the collision touch plate 114 will be pushed to the pressure sensor 122 and released from the pressure sensor 122. At this time, the alarm 121 sounds an alarm, and the push rod 127 is pushed synchronously. The second inclined surface on the push rod 127 contacts the first inclined surface at the top of the brake rod 125 to press the brake rod 12 downward. The brake rod 125 moves downward until the brake head at its top contacts the ground, and the brake head generates friction with the ground to stop the device from moving. After removing the obstacle, under the reset action of the buffer spring 115 and the reset spring 128, the collision contact plate 114 and the brake rod 125 return to their original positions, and construction can continue.
