Aerial ropeway steel wire rope anti-off device

An aerial ropeway steel wire rope anti-off device comprises a support rope wheel hanger and a support rope wheel fixed to the support rope wheel hanger. A steel wire rope of a rope clip is supported and fixed by the support rope wheel. A mandrel is perpendicularly fixed and connected to the transverse rod of the support rope wheel hanger and supported by a rotating roller. According to the aerial ropeway steel wire rope anti-off device, the mandrel and the rotating roller are mounted on the inside of the support rope wheel to effectively prevent the steel wire rope from falling off on the inside of the support rope wheel. The device is not in contact with the steel wire rope or the rope clip to avoid producing abrasion, collision and noise during the normal operation of the steel wire rope. The rotating roller in rotation can protect the steel wire rope to the most extent to avoid the pope clip from shifting due to friction even if the steel wire rope jumps upwards and in friction with the device during operation, so that the safety of people taking an aerial ropeway and the safe operation of the aerial ropeway are ensured. The device is simple in overall structure and very easy to mount and fix, does not need to change an original aerial ropeway and saves costs.
