摘要: A movable belt breakage prevention and catching system for a belt conveyor includes a detection device, two tracks, a plurality of catching devices, and a control system. The detection device is mounted on the belt conveyor, and is configured to detect whether a belt of the belt conveyor has a crack. The two tracks are symmetrically arranged on both sides of the belt conveyor, and the plurality of catching devices are symmetrically arranged on the two tracks. The control system is configured to control the plurality of catching devices to simultaneously catch the belt firmly when the detection device detects that the belt has a crack; and after firmly catching the belt, each catching device is able to unidirectionally move along with the belt along the track where the catching device is positioned.

摘要: 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.
