Broken belt catcher interlocking alarm device for belt conveyor

A broken belt capturing device interlocking alarm device for a belt conveyor comprises a belt conveyor PLC (programmable logic controller) control cabinet and a mechanical broken belt capturing device, and a PLC input terminal and a power terminal are arranged in the belt conveyor PLC control cabinet. The mechanical broken belt capturing device comprises a capturing beam and two mining intrinsic safety type magnetic proximity switches arranged at the two ends of the capturing beam, and one mining intrinsic safety type magnetic proximity switch is connected with a power terminal through a mining explosive-proof and intrinsic safety type audible and visual alarm and a control transformer. And the other mining intrinsic safety type magnetic proximity switch is directly connected with the PLC input terminal. By means of the interlocking alarm function between the broken belt capturing device and the belt conveyor control system after a broken belt fault occurs in the operation process, the belt conveyor can be st
