The invention relates to an anti-rollover monitoring device and method for operation of pipe hoisting equipment of a hydraulic excavator. The device comprises an angle sensor A, an angle sensor B, a horizontal tilt angle sensor and an alarm which are respectively connected with a controller, wherein the angle sensor A is arranged between a movable arm and a bucket rod; the angle sensor B is arranged at the hinging part of the movable arm and a rotary platform; and the horizontal tilt angle sensor is mounted on the rotary platform. The method comprises the following steps of measuring an angle signal A between a movable arm and a bucket rod, an angle signal B between the movable arm and a rotary platform and an inclination angle signal of the rotary platform relative to a reference ground plane; calculating the tipping moment generated by the hoisted object, the tipping moment generated by the bucket rod, the tipping moment generated by the movable arm and the anti-tipping moment; and calculating the total tipping moment and the safety moment of the hydraulic excavator, and controlling an alarm to give an alarm. According to the device and the method, the angle of the working face during operation can be monitored in real time, early warning can be given in time when the tipping risk occurs, and potential safety hazards in the operation process can be effectively eliminated.
