Novel rope-separation prevention device of aerial ropeway

The utility model discloses a novel rope-separation prevention device of an aerial ropeway and belongs to the field of mine conveying equipment. The novel rope-separation prevention device comprises rope pulleys. Coaxial auxiliary wheels are fixedly connected with the side of the rope pulleys. Diameter of the coaxial auxiliary wheels is smaller than that of the rope pulleys. The coaxial auxiliary wheels are provided with alarm contact switches. A limit switch is arranged on one side of each coaxial auxiliary wheel. The novel rope-separation prevention device can accurately drop in wheel grooves of the coaxial auxiliary wheels to ensure the aerial ropeway to normally run, and maintenance staffs timely reset steel ropes when hearing alarms to reduce unsafe factors, improve safety and reliability of the aerial ropeway and effectively prevent accidental injury accidents caused by rope separation in a large area during running of the aerial ropeway.
