The invention provides a hoisting rope loosening detecting device which comprises a foundation, rotating shafts, swing parts, inductive heads and proximity switches. The rotating shafts are hinged to the foundation. One end of each swing part is fixed to the corresponding rotating shaft, and the other end of each swing part is a free end. The free ends are used for being attached to traction ropes of a hoisting material conveying system and can swing along with loose-tight switching of the traction ropes. The proximity switches are arranged on the foundation, and the inductive heads are arranged at the free ends and can swing in the vertical plane along with the free ends. When the traction ropes are in the tight state, the inductive heads overcome the gravity of the free ends under the driving of pull force of the traction ropes to ascend to the parts outside the inductive areas of the proximity switches; and when the traction ropes are in a rope loosening state, the inductive heads fall back to the inductive areas under the driving of the gravity of the free ends, and thus the proximity switches are made to send out rope loosening signals. By means of the scheme, the problem that an exiting detection switch is likely to be crushed by the traction ropes, and consequently, a rope loosening detection result is not accurate can be solved. The invention further provides a hoisting material conveying system.
