Description

Technical Field

[0001] This utility model relates to the field of making holes at the bottom of a parallel surface, and more specifically to a portable auxiliary hole-making device for making holes at the bottom of a parallel surface. Background Technology

[0002] During the construction of expansion bolt holes for fixing cable hanger bases in the main control building cable interlayer of power system substations and thermal power step-up substations, as well as in the turbine hall cable interlayer of thermal power plants, it is necessary to drill holes in the ceiling to facilitate the subsequent installation of expansion bolts. However, the traditional method of drilling holes involves manually climbing a ladder and using an electric drill. Users need to hold the electric drill from below and drill upwards, which is physically demanding. Dust can easily enter the eyes during drilling, and users inhale a lot of dust, affecting their health. This method is inconvenient.

[0003] Therefore, those skilled in the art have provided a portable auxiliary hole-opening device for expansion bolt holes in ceilings to solve the problems mentioned in the background art. Summary of the Invention

The electric drill body is placed on the support plate, and the drill bit is parallel to the extension line of the lifting rod.

[0015] The advantages of this portable auxiliary drilling device for drilling holes at the bottom of a parallel plane are as follows: By setting an adjustment mechanism, pressing down on the pressure rod and cooperating with the limiting rod and the movable rod, the lifting rod can be raised and lowered, thereby raising and lowering the electric drill mechanism for convenient drilling. The mounting mechanism can be disassembled by cooperating with the mounting screw and mounting screw groove, facilitating disassembly and transportation. The support plate facilitates positioning of the electric drill body. Wrapping the strap around the outside of the electric drill body and hanging the hook on the hanging ring can fix the electric drill body, making it stable. By using a guide block and guide groove, the guide block slides within the guide groove, guiding the limiting rod and preventing it from shaking during movement. By setting a sliding groove on the mounting mechanism, the height of the drilling mechanism can be adjusted in the vertical direction, facilitating operation. For some precision operations, the drilling mechanism can be directly adjusted under the support of the adjustment mechanism. Attached Figure Description
