The invention discloses a building wall
punching device and an application method thereof, which belong to the technical field of construction machinery. A device for
punching holes in a building wall, comprising a
machine base, three fixed pipes are movably connected to the outer wall of the
machine base, a casing is fixedly connected to the inner wall of each fixed
pipe, the inner wall of the casing is connected to a fixing mechanism, and the outer wall of the
machine base is connected to a second Motor, the output end of the second motor is connected with a rotating rod, the outer wall of the rotating rod is connected with a second gear, the second gear is connected with the inner wall of the machine base in rotation, the outer wall of the second gear is engaged with the first gear, and the first gear is connected with the The outer wall of the fixed
pipe is connected with a
threaded rod on the outer wall of the first gear; the present invention can artificially assist the drilling of a wall with a small
outer space, so that the three fixed pipes are fixed on the wall and relatively retracted into the machine base, ensuring that the
drill bit Stable feed during drilling, avoiding
drill bit deviation during the drilling process, thereby ensuring the drilling quality.
