Provided in the present application is an intelligent tunnel drilling device, comprising: a six-axis robotic arm, a drilling machine mounting foundation, a drilling machine, limiting structures, a pressure sensor and an intelligent analysis host, wherein the intelligent analysis host has a data processing module and a control module; the data processing module is in data communication with the pressure sensor; the data processing module determines, by means of comparison, whether a drilling pressure is greater than a threshold value; and the control module cuts off a power source of the drilling machine in response to pressure data being greater than the threshold value. By means of the intelligent tunnel drilling device in the present application, when a drilling pressure is greater than a threshold value, a power source of a drilling machine is cut off, so as to prevent a shield plate from being destroyed and the drilling machine from being damaged due to the drilling machine drilling holes in a fixed bolt and structural reinforcement, ensure to the greatest extent that a drilling procedure is reliably performed, and prolong the service life of the drilling machine.
