Drilling tool with forcible entry function

Abstract

The invention discloses a drilling tool with a forcible entry function. The drilling tool comprises a power source, a drill rod, a positioning disc, a drill bit body and an impact rod body, the drill rod is installed at the output end of the power source, the positioning disc is installed at the tail of the drill rod, a positioning column is installed at the center of the lower surface of the positioning disc in a locking mode, a bearing assembly is installed at the bottom of the side wall of the periphery of the positioning column, and a positioning assembly is installed in the middle of the peripheral side wall of the positioning column. The drill bit body and the impact rod body can be quickly mounted and dismounted through the bearing assembly and the positioning assembly, subsequent quick dismounting is facilitated while stable operation of the drill bit body and the impact rod body is guaranteed, the overall machining range of equipment is enlarged, when forcible entry is needed, the impact rod body can be quickly replaced, auxiliary operation can be conducted without the help of external tools, meanwhile, under the cooperation of a diameter expanding assembly, the drilling diameter can be expanded later, the rapid diameter expanding effect is achieved, and the drilling efficiency of the drilling tool is improved.

Description

technical field [0001] The invention relates to the related technical field of drilling tools, in particular to a drilling tool with a rescue function. Background technique [0002] Drilling tools refer to tools related to drilling and drilling, mainly including drilling tools and metallurgical furnace drilling tools. When drilling in a specific situation, when it needs to be demolished, it is necessary to use other tools to assist, the function is single, and the practicability of the drilling tool is reduced. [0003] The traditional device has the following disadvantages: the existing drilling tools have some shortcomings in the use process, and can only drill for specific situations. Single, which reduces the practicability of the drilling tool. At the same time, the installation and disassembly of the drill bit is more cumbersome, prolonging the installation and disassembly cycle, and the current drilling tool has a small range of use, and the drill bit cannot be expan...

[0003] The traditional device has the following disadvantages: the existing drilling tools have some shortcomings in the use process, and can only drill for specific situations. Single, which reduces the practicability of the drilling tool. At the same time, the installation and disassembly of the drill bit is more cumbersome, prolonging the installation and disassembly cycle, and the current drilling tool has a small range of use, and the drill bit cannot be expanded during drilling. The range is dynamically adjusted, which reduces the drilling efficiency of the drill bit and increases the difficulty of the operation of the staff
