Method for monitoring tension balance and offset adjustment conditions of steel wire ropes of a multi-rope conveyor

摘要

A method for monitoring the tension equalization and offset adjustment states of steel wire ropes of a multi-rope conveyor using a device for monitoring tension equalization and offset adjustment conditions of steel wire ropes of a multi-rope conveyor, the apparatus comprising a wireless receiving and processing system (6) on the ground, tension equalizing devices (1) , several conveyor steel wire ropes (5) for conveying a conveyor container (3), and a conveyor container tension plate (3-1), which is provided on the top of the conveyor container (3), several tension compensation devices (1), which are at a distance on the conveyor container -Tension plate (3-1) arranged and respectively attached to the conveyor wire steel cables (5), each of the tension compensation devices (1) being provided with an offset sensor (2) thereon; a barometric altimeter (8) and a signal detection transmitter (4) which is connected to the barometric altimeter (8), both of which are arranged on a side wall of the conveying container (3), and wherein each displacement sensor (2) with the signal detection Transmitter (4) is connected by conductive cables; wherein the displacement sensors (2) are provided as drawbar displacement sensors, and wherein the expansion rod (2-1) of each displacement sensor (2) is hinged to a wedge-shaped cable ring (1-1) of the respective tension compensation device (1) via a bo the housing (2-2) of each displacement sensor (2) being fastened to a side plate (1-2) of the respective tension compensation device (1) via screws respective voltage compensation device (1) is measured via the offset sensor (2), the signal is transmitted to the signal acquisition transmitter (4), the signal acquisition transmitter (4) transmits the acquired signal to the wireless receiving and processing system (6), and the wireless receiving and processing system (6) sets an adjustment limit value for the respective voltage balancing device (1) according to the initial adjustment amount of the respective voltage balancing device (1); during the upward and downward process and the loading and unloading process of the conveying container (3) in the mine shaft (7), since the tensions on different conveyor steel wire ropes (5) are different, d The amounts of an offset adjustment to be adjusted differ between the conveyor steel wire ropes (5); wherein the respective tension compensation device (1), which is fixed to each conveyor steel wire rope (5), adjusts the tension on the conveyor steel wire rope (5) according to the tension on the conveyor steel wire rope (5), and the expansion rod (2-1) of the displacement sensor (2) on each tension compensation device (1) moves up and down together with the wedge-shaped rope ring (1-1) connected to the conveyor steel wire rope (5), thereby transmitting the offset signal to the signal acquisition transmitter; meanwhile the barometric altimeter ( 8) measures the depth of the conveying container in the mine shaft (7) and transmits the measured data to the signal detection transmitter (4); the signal acquisition transmitter (4) acquires the data from the barometric altimeter (8) and the displacement sensors in real time and stores the displacement adjustment amounts of the voltage compensation devices (1) and the corresponding depth of the conveying container (3) in the mine shaft (7) and then stores the acquired Transmits data to the wireless receiving and processing system (6); wherein the wireless receiving and processing system (6) processes the received data, the offset adjustment amount of the respective tension compensation device (1) connected to each conveyor steel wire rope (5), and the corresponding depth data of the conveyor container in the mine shaft (7) during the upward and outputs downward travel operation and the loading and unloading operation of the conveyance container (3), and judges the maximum amount of offset adjustment adjusted during the entire conveyance process and the depth of the respective tension equalizing device corresponding to the maximum amount of offset adjustment; wherein if the maximum amount of offset adjustment is greater than a preset offset limit, the wireless receiving and processing system (6) will issue an alarm.
