The utility model relates to the field of mining mechanical traction equipment. The utility model relates to a rope blocking device, in particular to a steel wire rope traction pedestrian booster. Thedevice comprises a fixing frame, the fixing frame is fixed to a roadway through a plurality of pre-buried bolts. a coaxial screw rod is arranged in the middle of the fixed frame; the inner end of thecoaxial screw rod is fixed on the fixing frame; wherein the outer side wall of the middle section of the coaxial screw rod is sequentially and movably sleeved with a rope supporting wheel and a ratchet wheel from inside to outside, the rope supporting wheel and the ratchet wheel can rotate around the coaxial screw rod, an anti-disengaging nut is arranged at the outer end of the coaxial screw rodin a fastened and screwed mode, a traction steel wire rope is arranged above the rope supporting wheel, and a rope clamping handle is movably connected to the traction steel wire rope in a clamped mode. The device is simple in structure and reasonable in design, the steel wire rope can be well prevented from falling off and drooping through the anti-falling structure, the steel wire rope is effectively prevented from deviating from the rope supporting wheel and deviating from the operation direction, and safe operation is kept.
