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.

Abstract: A chain fault diagnosis system and a chain fault diagnosis method for a scraper conveyor are provided. The diagnosis system includes a strain rosette attached on a top end surface of each sprocket tooth of the scraper conveyor. The strain rosette is connected to a signal gathering unit fixed on a scraper conveyor roller through a shielded conductor, the signal gathering unit sends a gathered signal to a wireless receiving device by means of wireless transmission, and the wireless receiving device transmits the gathered signal obtained thereby to an industrial control computer through a USB interface. The diagnosis method includes the following three steps: chain dislocation/skip fault judgment, chain breakage fault judgment and chain seizure fault judgment. A comprehensive monitoring of the chain state of the scraper conveyor is performed by measuring strain magnitudes in different directions of the sprocket tooth in real-time, transmitting the gathered signal to the industrial control computer via a wireless transmission method and dynamically diagnosing the faults of seizure, dislocation, skip and breakage of the scraper conveyor chain based on the obtained strain data.

Abstract: A gear-track-detachable driving device in a monorail crane for a steep slope includes a driving mechanism, a traveling mechanism, a four-bar linkage mechanism, a connection mechanism, a meshing track plate and transition track plates. The driving mechanism includes driving motors, meshing gears, a bearing rod, and a bearing plate. The traveling mechanism includes traveling wheels, clamping wheels, a shell and telescopic struts. The linkage mechanism includes first and second rockers, a linkage, and a cylinder. The connection mechanism includes fixation plates, a connection plate and connection bolts. When the crane travels to the slope front, the cylinder drives the linkage mechanism to send the meshing gears onto the transition track and adjusts the linkage mechanism into a dead point state, and the telescopic struts are locked. After the crane enters the slope, the meshing gears cooperate with the meshing track plate to provide an auxiliary drive for the crane.
