Core drilling machine for energy-saving exterior wall detection

Abstract

The invention discloses a core drilling machine for energy-saving exterior wall detection. The core drilling machine comprises a core drilling bit, a drill bit assembly joint, an extension joint, a drill hole transmission cylinder, a drill hole transmission body, a motor, a control handle and an auxiliary holder, wherein the control handle is locked at the bottom end of the motor; the motor is electrically connected with the control handle; the drill hole transmission body is locked at the left end of the motor; the motor is fastened with the drill hole transmission body; the middle of the left end of the drill hole transmission body is fastened with the middle of the right end of the extension joint by virtue of the drill hole transmission cylinder; the extension joint is a cuboid; the auxiliary holder is locked on the right side of the bottom end of the extension joint; the drill bit assembly joint is fastened to the upper side of the left end of the extension joint; and the core drilling bit is locked through the drill bit assembly joint. When the core drilling machine disclosed by the invention is used, due to a mechanism composed of a gear, a rack, a spring, an ejector rod andthe like on the equipment, upper and lower protection plates are automatically unfolded during equipment drilling, so that the user can be protected in use, and the user is well prevented from splashinjury during drilling.

Description

technical field [0001] The invention is a core drilling machine for external wall energy-saving detection, which belongs to the field of core drilling machines for external wall energy-saving detection. Background technique [0002] Exterior wall section detection is a process carried out after the construction of the exterior wall is completed and before the acceptance of the energy-saving sub-project. Its main purpose is to test whether the energy-saving structure of the exterior wall of the building with insulation layer meets the design requirements. The testing equipment used includes core drilling machines, digital cameras and steel rulers. The core drilling machine is used to drill the insulation layer samples of the outer wall. The depth of drilling core samples is to drill through the insulation layer to reach the surface of the structural layer or the base layer, and can drill through the wall if necessary. [0003] When the prior art is used, it is easy to cause ...
