Large-deflection-angle groove-disengaging-preventing mechanism for steel wire rope of crane

The invention discloses a crane steel wire rope large-deflection-angle groove-disengaging-preventing mechanism, and relates to the technical field of cranes, the crane steel wire rope large-deflection-angle groove-disengaging-preventing mechanism comprises a supporting frame, a steel wire rope is arranged on the tops of clamping mechanisms, cleaning mechanisms are arranged on the opposite sides of the two clamping mechanisms, and clamping mechanisms are arranged on the tops of the cleaning mechanisms. According to the crane steel wire rope large-deflection-angle groove-disengaging-preventing mechanism, in the steel wire rope limiting process, friction between the top in a chuck and a steel wire rope is prevented, so that the service life of the steel wire rope is shortened, and the situation that in the moving process of the steel wire rope, dust adhering to the outside falls into a sliding frame, and consequently a large amount of dust is stored in the sliding frame is prevented; dust increases abrasion betw
