Abstract: A multiple-state health monitoring apparatus for critical components in a hoisting system includes a frame. The frame is a square structure formed by welding a plurality of rectangular steels. A steel wire rope is arranged around a periphery of the square structure. A power system, a friction-and-wear apparatus, a brake-and-wear apparatus, and a tensioning apparatus are sequentially mounted from left to right on a bottom layer of the square structure. A bearing signal collection system, a tension sensor, an excitation apparatus, and a steel-wire-rope image collection system are sequentially mounted from left to right on a top layer of the square structure. The steel wire rope sequentially passes through all the apparatuses or systems and is driven by the power system to perform circling. All the apparatuses or systems are used to monitor an operation status of the steel wire rope.

Abstract: The present disclosure discloses a method for collaboratively controlling a multi-channel braking system of a mine hoist, including obtaining the abrasion loss of the brake shoe by detecting position information of the brake shoe of each of disc brakes in real time, dividing abrasion loss levels by determining different abrasion degrees of the brake shoe, formulating three braking force distributing modes: an average distribution, a proportional distribution, and an index distribution according to the abrasion loss levels, thereby dynamically adjusting a set braking pressure of each of the disc brakes, tracking and controlling the set braking pressure through the disc brakes by adopting a pressure closed-loop control method by utilizing a pressure signal feedback from an oil pressure sensor, implementing a collaborative braking control of the multi-channel braking system of the mine hoist based on the abrasion loss of the brake shoe.
