The utility model discloses a searching protection device capable of reducing electrical faults of an adhesive tape. The device comprises an electrical control branch box and an electrical control main box, the electric control branch box is connected with the electric control main box through a wire, a detection circuit is installed on the inner side of the electric control branch box, and the detection circuit comprises a pull rope relay KL1, a pull rope indicator lamp HL1, a pull rope coil KL1, a deviation switch KF1, a deviation indicator lamp HF1 and a deviation coil KF1. The utility model discloses a searching and protecting device capable of reducing adhesive tape electrical faults. the electric control sub-box is mounted in the center of the maintenance line; an intermittent faultjudgment method is adopted; the electrical control length is shortened; when a fault signal is detected, the whole rubber belt can be shut down, and meanwhile, the pull rope indicator lamp HL1 gives an alarm and the red lamp is turned on, so that an electrical maintainer can quickly and timely check a faulted area, the time for checking a fault point of the rubber belt is greatly shortened, the transportation volume of the rubber belt is increased, and the production cost is reduced.
