Perforating device for constructional engineering

Abstract

The utility model discloses a perforating device for constructional engineering, which belongs to the technical field of perforating devices and comprises a placement bottom plate, an inverted U-shaped upper cover is connected to the upper end of the placement bottom plate, a sliding plate capable of sliding up and down is mounted in the inverted U-shaped upper cover, and a second driving motor is mounted at the upper end of the sliding plate. The rotating end of the second driving motor penetrates through the sliding plate and is connected with a drill bit, when the arranged sliding plate is pressed downwards, the sleeve and the mounting plates on the two sides make contact with a plate to tightly press the plate, the sliding rods on the two sides are pressed downwards to slide upwards along the through holes and compress the first springs, and the drill bit makes contact with the plate and drills the plate; the air inlet end of an air suction pump is connected with an air hole in one side, and the air suction pump sucks air, so that external air enters the sleeve through an air hole in the other side and enters a collecting box through an air inlet pipe to be filtered; cleaning can be completed by cleaning the filter element in the collecting box, so that cleaning is more convenient.
