Abstract: Disclosed is a method for estimating tension of a chain of a scraper conveyor, belonging to a method for estimating chain tension. The method comprises the following steps: embedding strain sensors in a plurality of scrapers of a scraper conveyor to measure the tension of weak coupling points between the scrapers and chains, converting acquired sensor signals into data signals through an A/D conversion unit, transmitting the data signals to a data control center using a wireless transmission module, further processing the tension data information of the weak coupling points through the data control center, establishing a chain tension distribution model, and determining an the estimated tension of the chain of the scraper conveyor. The method provided by the present invention is simple, efficient and practical, and the estimation of tension of the whole continuous moving chain is completed by the tension measurement at limited positions of the chain. The chain of the scraper conveyor is meshed with a sprocket and continuously moves in a middle trough and its tension also changes in real time along with the load; the strain sensors are arranged on the scrapers to measure the tension of the weak coupling points between the scrapers and the chains, and the estimation of tension of the whole chain is completed by tension measurement at limited positions on the chain.

Abstract: Systems and methods for detecting a layer-to-layer transition of a lifting steel wire rope on a reel are described. The system includes a reel assembly for winding a steel wire rope on a reel and a tensioning assembly for tensioning a segment of said steel wire rope. The system further includes a loading assembly and a lead screw sliding assembly. The loading assembly provides a vertical loading to the tensioning assembly so as to generate a loading force between the tensioned steel wire rope and the steel wire rope wound around the reel. The lead screw sliding assembly drives the tensioning assembly so as to move on a horizontal guide rail to generate a relative displacement between the tensioned steel wire rope and the steel wire rope wound around the reel. The tensioning assembly is connected to the loading assembly via a first threaded rod and a static torque sensor.

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.
