The invention discloses a self-propelled road pavement lancing device for municipal
engineering. The self-propelled road pavement lancing device comprises a support seat, wherein a U-shaped frame is arranged in the middle of the upper end of the support seat, an S-shaped bent
pipe is mounted at the upper end in the U-shaped frame, a rotating shaft is mounted in the middle of the U-shaped frame, acam is mounted in the middle of the upper end of the rotating shaft, a limiting ball is mounted at the left end of the
cam, a limiting rod is connected to the left end of the limiting ball, a limitingplate is mounted at the left end of the limiting rod, a telescopic rod is mounted in the middle of the left end of the limiting plate, a telescopic plate is connected to the left end of the telescopic rod, and a water guiding cylinder is
mount outside the telescopic plate; and a
cutting frame is mounted in the middle of the lower end of the support seat, a
cutting wheel is mounted in the middle of the
cutting frame, a driving shaft is mounted in the middle of the cutting wheel, a driving gear is connected to the other end of the driving shaft, a rotating gear is meshed to the upper end of thedriving gear, and a dust-removal cover is mounted outside the top end of the cutting frame. According to the self-propelled road pavement lancing device, a pavement can be
cut, meanwhile, dust produced during the lancing can be removed, and the cutting wheel can be cooled.
