| description | The utility model provides a crack repairing device for highway pavement maintenance, which belongs to the technical field of pavement maintenance and comprises a first traction arm. The second traction arm is rotationally connected to one side end of the first traction arm through a rotating shaft; the limiting assembly comprises a limiting sleeve, a limiting sliding rod, a limiting sliding groove and a limiting spring, the limiting sleeve is rotationally connected to one side end of the second traction arm through a rotating shaft, the limiting sliding groove is formed in one side end of the limiting sleeve, and the limiting sliding rod is rotationally connected to one side end of the first traction arm through a rotating shaft and slides in the limiting sliding groove; and the distance between the discharge port and the pavement is always fixed through the movement of the second traction arm, so that the repair asphalt can be accurately poured into the cracked road seam.
