Description

Technical Field

[0001] The utility model relates to the technical field of engineering technology detection, in particular to a ground hollow drum knocking device for engineering technology detection. Background Art

[0002] Hollowing is caused by the presence of air in the original masonry and plaster layers. During testing, a thumping sound is heard when lightly tapping the plaster and leveling layers with a hollowing hammer or a hard object. "Hollowing" in housing quality generally refers to the hollowing phenomenon that occurs between the floor, wall, and ceiling finishing layers (plastering or tiled) and the structural layer (concrete or brick walls) due to loose bonding and adhesion. This phenomenon is commonly known as "two layers of skin."

[0003] Chinese patent number CN217484255U discloses a ground hollow drum knocking device for engineering technical detection. When the driving plate in the device rotates in the clockwise direction, it will drive the driven plate to move upward, thereby driving the lifting rod to move upward. At this time, the spring is compressed. When the driving plate disengages from the driven plate during continuous rotation, the spring extends, thereby driving the lifting rod to move downward, so that the knocking hammer at the bottom end of the lifting rod hits the ground, realizing the mechanization of ground hollow drum detection, high efficiency, time saving and labor saving. However, the knocking range of the device is small, and it needs to be constantly pushed to change the knocking position, which wastes manpower. For this reason, we provide a ground hollow drum knocking device for engineering technical detection. Utility Model Content
