[0042] In order to solve the problem that the prior art cannot effectively gouge the two sides of cracks with different widths, so that the adhesion of grouting material and original pavement will be affected, thereby causing poor adhesion after grouting, leading to the problem that the repaired cracks are easy to crack again. Figures 1-5 As shown in the figure, an asphalt pavement maintenance device is provided, which comprises a handheld moving frame 1 and a gouging mechanism 2 arranged on the handheld moving frame. The handheld moving frame 1 comprises two supporting rods 3, a connecting rod 4 connecting the two supporting rods 3, and a handle 5 arranged on the connecting rod. Universal wheels 6 are arranged on the supporting rods 3. The gouging mechanism 2 comprises a connecting structure 7 movably arranged on the supporting rod 3, and a gouging structure 8 arranged on the connecting structure 7 for gouging cracks. The gouging structure 8 comprises a rotating shaft 9 rotatably arranged on the connecting structure 7, a gouging disc 10 arranged on the rotating shaft 9, and gouging teeth 11 arranged on both sides of the gouging disc 10. The gouging teeth 11 on both sides are arranged on the two semicircular structures of the gouging disc 10, respectively. A motor 12 is arranged on the connecting structure 7 and connected with the rotating shaft 9.
[0043] In practice, when the crack of the asphalt pavement needs to be repaired and maintained, the chiseling disc provided with the chiseling teeth 11 on one side in the device is placed at any position or one end of the crack, the motor is started to drive the rotating shaft and the chiseling disc to rotate, the construction personnel control the universal wheel 6 to drive the chiseling disc 10 in the chiseling mechanism on the supporting rod 3 to move back and forth along the width direction of the crack through the handle 5, the chiseling teeth 11 on both sides of the chiseling disc are in contact with the side wall or both side walls of the crack at the same time to chisel, after the chiseling of both sides of the crack at the current position is completed, the chiseling disc 10 is moved to the direction of the crack path, and then is moved back and forth along the width direction, so that the crack is chiseled quickly. In the embodiment, the chiseling mechanism is arranged on the handheld moving frame, the chiseling disc and the chiseling teeth on one side are placed in the crack before the crack of the asphalt pavement is filled, the rotating shaft drives the chiseling disc to rotate by starting the motor, the chiseling teeth on one side are chiseled in contact with the crack, and the chiseling mechanism is moved along the length direction of the crack by the construction personnel holding the handheld moving frame, and at the same time, the chiseling mechanism is moved in the width direction of the crack. Since the chiseling teeth are arranged on the two half-circular structures of the chiseling disc, the distance between the two chiseling teeth arranged on the chiseling disc can be avoided to be too large, the chiseling disc cannot be placed in a relatively narrow crack for chiseling, and meanwhile, the chiseling teeth can chisel the side edge of the crack from the upper part of the crack edge downward when the chiseling disc moves along the width direction of the crack, so that the two side edges of the crack with different widths are effectively chiseled quickly, the bonding force between the grouting material and the original pavement is good, and the problem that the repaired crack is prone to cracking again is effectively avoided.
