AUTOMATIC CLIMBING DEVICE FOR GATE STEEL WIRE ROPE

The invention relates to an automatic climbing device for a gate steel wire rope, and solves the problems of low working efficiency, high labor intensity and potential safety hazards caused by manualcleaning and maintenance of the gate steel wire rope. The device comprises an outer frame and an inner frame which are slidably arranged on a gate steel wire rope in a sleeving mode. The outer frame and the inner frame can slide relatively; the outer frame and the inner frame are respectively provided with a rack and a gear which are mutually meshed; the rack extends in the axis direction of the gate steel wire rope. The gear is driven by a positive and negative rotation motor, an outer clamping device capable of loosening/holding a gate steel wire rope is arranged on the outer frame, an innerclamping device capable of loosening/holding the gate steel wire rope is arranged on the inner frame, and an upper carrying plate and a lower carrying plate are arranged at the two ends, in the axialdirection of the gate steel wire rope, of the outer frame respectively. Axial relative sliding is achieved through the gear and the rack, the gate steel wire rope is alternately clamped through cooperation of the inner clamping device and the outer clamping device of the inner frame and the outer frame, and stepping climbing of the device along the gate steel wire rope is achieved.
