Abstract: The disclosure discloses a system for controlling a multi-point synchronous braking of a monorail hoist and a utilization method thereof. The system comprises a contact detection unit, a common end roller unit, a hydraulic unit, a synchronous control unit and connection cables. The contact detection unit is installed on a brake shoe of a monorail hoist. The common end roller unit is installed on a travelling track and connected with a frame of the monorail hoist. The contact detection unit includes a tube in connection with the brake shoe. A metal probe corresponding to the travelling track is arranged inside the tube. A circular boss is formed on the metal probe. A limiting bolt corresponding to the circular boss is formed on an inner side wall of the tube. The metal probe is contactable with the travelling track or the limiting bolt when the brake shoe brakes.

Abstract: The present disclosure provides a system for monitoring a scraper chain based on a measurement on transmittance of a torsion spring and a method thereof. The system includes a sprocket-wheel torsion detection device, a fixing device, a wireless receiver, an A/D converter and an industrial computer. In the method, the relative torsion of the two sprocket wheels is converted into the density change of the torsion spring, the light transmission area is converted into the current value by the laser sensing panel, a varying range of the torsion spring is calculated by the industrial computer through the preset threshold and its own program to monitor the operating conditions of the chain. The method has a novel concept, a stable and reliable system, and a high promotion value.

Abstract: The disclosure discloses a device for detecting idling time of a brake shoe of a monorail hoist and a detection method thereof. The device includes a contact detection unit, a common end roller unit, an idling time detection unit and detection lines. The contact detection unit installed on a brake of the monorail hoist includes a tube in connection with the brake shoe. The common end roller unit is installed on a frame of the monorail hoist and corresponds to a travelling track. A metal probe corresponding to the travelling track is arranged inside the tube. A limiting bolt corresponding to a raised cylindrical block formed on the metal probe is formed on an inner side wall of the tube. The metal probe is contactable with the travelling track or the limiting bolt when the brake shoe brakes.
