Perforating device for concrete wall surface

Abstract

The invention discloses a perforating device for a concrete wall surface, relates to the technical field of perforating equipment, and solves the problems that an opened circular hole is not perfectly-circular because internal-external staggering is caused due to the irregularity of manual adjustment for a surrounding track of an electric drill, and high physical power consumption is caused because a worker generally needs to stand and violently pushes the electric drill with a hand during drilling. The perforating device for the concrete wall surface comprises an installation plate, a supportrotary shaft, a pushing frame and a base, wherein an electric drill is installed on a top end section of the installation plate in a manner of being locked forwards; the rear half section of the support rotary shaft is rotationally installed on a location shaft sleeve in a penetrating manner, and a worm gear is installed at the rear end of the support rotary shaft in a sleeved manner; and a saddle is installed on the rear half section of the base in a supporting manner, a location shaft sleeve is supported and welded to the middle part of the base, and two bevel gears are rotationally installed on a vertical supporting plate at the bottom of the location shaft sleeve in the form of left-right correspondence. According to the perforating device for the concrete wall surface, two guide wheels are capable of ensuring that a rotary ring can still be rotationally connected with two pushing frames during normal self-rotation.

Description

Technical field [0001] The invention relates to the technical field of punching equipment, in particular to a concrete wall punching device. Background technique [0002] Nowadays, some houses or construction sites will make round holes in the concrete due to their needs. Workers need to place the electric drill on the concrete first. After the worker fixes the electric drill on the concrete, the worker needs to start the electric drill to rotate. The electric drill rotates to drill the concrete. When a worker uses an electric drill to drill concrete, the worker generally needs to push the electric drill forward intermittently so that the electric drill can drill different thicknesses of concrete. When the worker uses the electric drill to drill a hole, the worker needs to replace the electric drill on the concrete After the worker repeats the above operation again, he can drill another hole in the concrete. When the worker uses an electric drill to drill a circle of holes in the...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a concrete wall punching device to solve the problem that when opening a large-diameter round hole in the above-mentioned background technology, the worker needs to manually rotate and adjust the drilling position of the electric drill on the wall for many times, so that the electric drill can Circumferential drilling, the operation process is cumbersome and inconvenient, and the manual adjustment of the electric drill's orbit is irregular, and the inside and outside will be uneven, resulting in a round hole that is not a perfect circle, and the worker usually needs to stand and push the electric drill with his hands when drilling, which consumes a lot of physical strength , Poor comfort when standing for a long time, easy to fatigue
