Concrete structure opening device

Abstract

This utility model belongs to the field of concrete structure construction technology, and particularly relates to a concrete structure drilling device. The concrete structure drilling device includes a driving mechanism; a connecting rod connected to the driving mechanism; and a drilling barrel mechanism, which includes an upper drilling barrel and a lower drilling barrel connected thereto. The end of the connecting rod away from the driving mechanism is connected to the upper end of the upper drilling barrel, and the lower end of the lower drilling barrel is provided with drill teeth. The lower end of the upper drilling barrel and the upper end of the lower drilling barrel are provided with mutually cooperating detachable connection structures, which allow for detachable connection between the lower end of the upper drilling barrel and the upper end of the lower drilling barrel.
