The invention discloses a tail rope twist removing state monitoring device which comprises a long-acting battery, an eddy current sensor, a sensor fixing device, a sensor front-end device, a wireless receiving and transmitting module, an antenna, a state monitoring system and an anti-explosion protection box. According to the monitoring technology, a signal generated by a tail rope suspension device rotating table bolt is monitored through the eddy current sensor, the signal is processed by the sensor front-end device and fed back to the state monitoring system, and the signal is compared with a built-in rotating parameter and then sent out by the wireless receiving and transmitting module through the antenna, so that communication with a mine hoisting system is achieved in real time, real-time feedback is achieved when abnormality occurs, and normal operation of the mine hoisting system is ensured. The long-acting battery supplies power to the whole device, the sensor fixing device is used for installing the eddy current sensor, and the anti-explosion protection box is used for installing the module, so that the tail rope twist removing state monitoring device provided by the invention achieves a safety isolation effect. According to the tail rope twist removing state monitoring device provided by the invention, an external power supply and a communication cable are not needed, so that the installation technology difficulty is small, the state of a tail rope can be monitored, self-monitoring can be achieved at the same time, and stability and reliability are achieved.
