Description

Technical Field

[0001] The utility model belongs to the technical field of drilling devices at construction sites, in particular to a small drilling device. Background Art

[0002] A construction site refers to a specific place where construction activities are carried out. It is the place where buildings are transformed from design drawings to physical structures. A series of construction operations will be carried out on the construction site. The construction content of the construction site covers the entire process from site preparation to the completion of the main structure of the building, internal and external decoration, installation of facilities, and final acceptance. Drilling construction on the construction site is one of the common basic construction processes in construction projects, mainly including various types of drilling operations required in the stages of foundation treatment, foundation engineering, structural engineering, and installation engineering. The different drilling areas and the size of the drilling holes on the construction site determine the different drilling equipment used. Some small drilling devices are often used in some drilling construction on the construction site to adapt to the complex construction site and facilitate the movement of the drilling device to improve the construction efficiency. However, most of the small drilling devices commonly used in construction sites cannot be adjusted to a certain angle, and the actual hole position required for drilling operations in the shock-absorbing construction site is often not fixed. Sometimes the hole position needs to be tilted to achieve a better construction effect.

[0003] Secondly, small drilling devices that cannot be adjusted in angle may require the operator to raise the device and perform other operations such as tilting the drill rod to achieve the corresponding drilling purpose when the hole position needs to be tilted. This operation method has certain safety hazards and may cause certain safety injuries to the operator.

[0004] In summary, the small drilling device used in construction sites cannot adjust the drilling angle and there are some problems in use, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
