Description

technical field

[0001] The invention relates to a positioning and drilling device for multi-standard expansion bolts of columns, belonging to the technical field of construction devices, in particular to a positioning and drilling device for multi-standard expansion bolts of columns. Background technique

[0002] Columns are widely used in the fields of construction and mechanical equipment as support rods, and columns are generally fixed with expansion bolts. Before installing the columns, it is necessary to drill holes in the ground according to the distance between the four expansion bolt installation holes at the bottom of the column, and then use expansion bolts to fix them. Bolts fix the column, but when drilling holes on the ground, the arm is easily impacted by the impact drill, causing the hole position to be deviated and skewed, which will cause inconvenience to the installation of the column. Therefore, a The multi-standard expansion bolt positioning and drilling ...
