Abstract
The utility model discloses steel wire rope groove hopping preventing protecting equipment for logging which comprises a support, a pulley, a pair of lifting rings, a pair of clamping plates, a pair of sliding sleeves, a rotating shaft, a rope pressing block, a plurality of waist holes, a pair of fasten bolts and a limiting limit stop. The pulley is arranged between the pair of clamping plates. The rotating shaft is arranged in the center of pulley and the clamping plates. The pulley rotates with the rotating shaft as a center. A steel wire is coiled on the pulley. The clamping plates are movably connected with the support through the sliding sleeves. The clamping plates and the pulley slide vertically along the support. The lifting rings are respectively arranged at the top and the bottom of the clamping plates. The rope pressing block is arranged at the top of the pulley. The two ends of the rope pressing block are connected with the waist holes through the fasten bolts. The limit stops are arranged on the clamping plates and are connected with the rotating shaft. The steel wire rope groove hopping preventing protecting equipment can control the rotating speed and the rotation turns of the pulley so as to control the descending distance and the descending speed of the steel wire rope and balance the stress received by the steel wire rope. The rope pressing block is used for pressing the steel wire rope, so that the steel wire rope is prevented from fracturing or groove-hopping.
