Study On The Straining Chain And Monitoring Chain System Of Scraper Conveyor

The scraper conveyor's main working places are production face, driving face and coal washery etc. It has many merits, for example, because the scraper conveyor's body is low, its floor space is small; it can bend flatly and vertically; its structure strength is high and so on. So far the scraper conveyor is unique transport equipment of working space, for its special construction and the good adaptability in formidable work environment. The flight link is a haul component of scraper conveyor. In working process, the flight link will generate elastic distortion with the continuous effect of dynamic load and steady load acting on it. The pitch of chain is longer the chain is looser. The chain may be stack at the chain pulley or be jammed. Once the flight link is wore excessively, the accident of chain damage will happen. In working face, when the working face is impelled, the scraper conveyor is also lengthened. It is a hard work to lengthen chain continually, not only waste physical strength...
