Beschreibung
Zusammenfassung:	The utility model discloses a mechanical arm for tunnel construction, which is used for moving drilling equipment and comprises a mounting seat, a rotary arm, a telescopic arm, a variable-amplitude oil cylinder and an integrated mounting mechanism. A slewing mechanism is arranged at the top of the mounting seat; the bottom of the rotary arm is installed on the rotary mechanism, and the rotary mechanism can drive the rotary arm to rotate relative to the vertical axis direction of the rotary arm. The telescopic arm comprises a reference section and a telescopic section connected to one end of the reference section through a telescopic mechanism; one end of the reference section deviating from the telescopic section is rotationally connected to the top end of the rotary arm; the fixed end of the variable-amplitude oil cylinder is connected to the rotary arm, and the telescopic end is hinged to the reference section; the integrated mounting mechanism is arranged at the end, away from the reference section, of the
