The invention provides a method and apparatus for monitoring Spannungsausgleichs- and offset adjustment states of steel wire ropes of a multi-piece conveying device. The apparatus mainly includes a displacement sensor which is mounted on a steel wire rope-voltage compensation device, a signal acquisition transmitter which is adapted to store signals of the displacement sensor, and to transmit, a barometric altimeter, which is adapted to detect the depth of a mine shaft where a delivery tank is located, and a wireless receiving and processing system that is disposed at the shaft mouth of a mountain Bausch at night. The method comprises the steps of: collecting the offset adjustment amounts of the stress-balancing devices which are connected to all the hoisting ropes of the conveyor vessel and the corresponding depth position of the feed container during the upwards and downwards driving operation of the conveying container by means of the signal detection channel; Overall maximum offset adjustment amount, which is measured during the entire conveying operation, and the corresponding voltage adjusting device and corresponding depth of a receiving and processing data about said wireless receiving and processing system; and, sounding an alarm if the maximum adjusted offset fails is greater than a predetermined adaptation threshold. The detection method is simple and convenient to implement. The device has a simple structure, provides accurate results ready and has a high reliability. Therefore, the problem is that manual measurement methods are time consuming and labor intensive, effectively solved.
