Description

Technical Field

[0001] The present application relates to the technical field of wall punching, and in particular to a wall punching device. Background Art

[0002] Most existing building structures are reinforced concrete structures. During the later construction and decoration of the building, it is necessary to drill holes in the building to accommodate the installation of subsequent equipment, etc. However, since concrete buildings are too hard, drilling holes is an extremely physically demanding task.

[0003] A patent document with publication number CN219618181U in the prior art provides a building wall punching device, which is equipped with a punching device body, a groove, a second screw rod, a second rotating drive mechanism, a movable plate, a third rotating drive mechanism, a drill bit, an arch frame, a strip hole and a fastener. The third rotating drive mechanism drives the drill bit to rotate, and at the same time, the second rotating drive mechanism drives the second screw rod to rotate, so that the drive block and the movable plate move along the second screw rod, driving the drill bit to move toward the direction close to the building wall and drill a hole. No manual operation is required, which saves time and effort. At the same time, the position of the arch frame can be adjusted according to the required drilling depth, so that the movable plate moves to the arch frame and is blocked, and the forward drilling is stopped.

[0004] Although the above-mentioned prior art solution can achieve no manual operation through the automatic movement of the drill bit, it still has the following defects: since drilling will generate a huge reaction force, and the base of the device cannot provide sufficient support, the prior art has safety hazards such as drill bit shaking and breaking during drilling.

[0005] In view of this, we propose a wall punching device. Utility Model Content

At this time, the limit frame will drive the movable plate to move under the limit of the installation frame, and finally the movable plate can drive the drilling machine to automatically drill holes through the fastening plate.
