Abstract
The invention discloses an intelligent pneumatic jacking anchor drilling rig capable of automatically adjusting jacking push force. The drilling rig comprises a drill bit, a drill stem, a transmission device, a drill stem pneumatic motor and a telescopic air leg. An operating arm, a pneumatic valve, an air intake pipe communicated with the pneumatic valve, an indicator light and a control button are further arranged on the side face of the intelligent pneumatic jacking anchor drilling rig capable of automatically adjusting jacking push force, wherein the indicator light and the control button are installed on the operating arm. A sensor and a central controller are arranged on the front face of the intelligent pneumatic jacking anchor drilling rig capable of automatically adjusting jacking push force, wherein the sensor is arranged on a connecting sleeve, making contact with the jacking anchor drilling rig body, of the drill stem.
