The coal unstacking line process of Qinhuangdao Port Coal Phase 5 has a total of 27 belt conveyors.Due to long-term operation,their belts are severely worn due to aging,and problems such as belt edge pulling and surface wire leakage often occur.If they cannot be effectively detected,the damage degree of the belt will be ex-panded,and in severe cases,the entire belt will be completely damaged.In response to this issue,Coal Phase 5 inde-pendently designs and develops a new protection device to prevent the expansion of the longitudinal tear degree of the belt based on multi-point detection,which fundamentally solves the defects in the original design that the alarm from the protective device is delayed or absent when the belt is longitudinally torn,and the protective device mis-takenly alarms when the belt is not actually longitudinally torn,and lays a solid equipment foundation for the com-pany's safe and stable production.
