Abstract
A device for monitoring tension equalization and displacement adjustment states of steel wire ropes of a multi-rope hoister includes a displacement sensor mounted on a steel wire rope tension equalization device, a signal acquisition transmitter designed to store and transmit signals of the displacement sensor, a barometric altimeter designed to detect the depth of a mine shaft where a hoisting container is located, and a wireless receiving and processing system arranged at the well mouth of the mine shaft. A method for use includes collecting the displacement adjustment amounts of the tension equalization devices connected with all the hoisting ropes of the hoisting container and the corresponding depth position of the hoisting container during the up-down running process of the hoisting container by means of the signal acquisition transmitter; judging the maximum displacement adjustment amount measured in the entire hoisting process and the corresponding tension adjustment device and corresponding depth, by receiving and processing data via the wireless receiving and processing system; and, giving an alarm when the maximum adjusted displacement is greater than a preset adjustment threshold.
