Device for monitoring levelness of machine body of heading machine

The utility model provides a device for monitoring the levelness of a machine body of the heading machine. The device for monitoring the levelness of the machine body of the heading machine comprises a double-shaft type inclination angle sensor, a programmable logic controller (PLC) and a displayer, wherein the double-shaft type inclination angle sensor is connected with the PLC through a cable, and the PLC is connected with the displayer through a cable. The device guarantees the pitching angle and the toll angle of the heading machine when the heading machine works in a roadway, is capable of monitoring the levelness of the machine body in real time, and avoids serious errors in the heading direction of the roadway, thereby avoiding repeated work of correction after errors occur. The device is simple in structure, is achieved by adding the double-shaft type inclination angle sensor to an existing common electric system, is obvious in effect, and is capable of monitoring the levelness of the machine body, th
