Abstract: In order to avoid the secondary damage caused by the mine steel wire for rope slot liner wear, this article introduces the coal mine lift locomotive tank device. According to the site usage make the installation plan and the support, the coal mine based on PLC design pulley turning device control, set the pulley deflection and vibration performance test device and radial feature detection device, experimental platform is established. Pulley for experiment study found: pulley from the most to the left of the fourth pulley to the right on the first day of the wheel, the diameter of the pulley of the most prominent position is more and more big, the concave of the diameter of the location from the fourth pulley to gradually reduce, the next day to the first day when the wheel increases slightly, but the wear of head sheave present the trend that more and more serious. According to this, the cutting mechanism based on the turning device, eliminates the wear of the wheel liner, and guarantees the safety of mine hoist.
