Abstract

The invention discloses a method for replacing a steel wire rope of a crane. The method comprises: preparing a new steel wire rope, the length of which is equal to the sum of the lengths of two old steel wire ropes; placing the moving pulley block in the work area, and removing the limit switch on the reel; Cut off the old steel wire rope; connect the cut two rope ends on the side of the movable pulley block to the two rope ends of the new steel wire rope respectively; remove the pressure plate on the drum, and turn the drum until the joints of the old and new steel wire rope ends are wound on the drum. and the new wire rope is wound around the reel at least once; disconnect the two ends of the old and new wire ropes, and press and fix the two ends of the new wire rope with two pressure plates; cut off the new wire rope, and the cutting position is located center; connect the two new rope ends formed after cutting with the two connectors respectively; arrange the new steel wire rope and install the drum limit switch. The crane wire rope replacement method of the invention has high synchronization, improves work efficiency and reduces labor consumption.

Description

technical field [0001] The invention relates to the technical field of crane equipment installation, in particular to a method for replacing steel wire ropes of a crane. Background technique [0002] In crane equipment, the wire ropes connecting the drum and the balance beam are two independent wire ropes. In the prior art, the crane wire rope is used in the following conditions: figure 1 As shown, the wire rope winding is usually that the first wire rope head is fixed on the drum by the pressure plate, a part of the wire rope is wound on the drum, and then passes through the first movable pulley of the movable pulley block on the same side as the pressure plate, and the fixed pulley on the same side. A fixed pulley of the pulley block and the second movable pulley of the movable pulley block, and then the other rope end of the steel wire rope is fixed on the balance beam through the connecting piece. The second steel wire rope is arranged symmetrically with the first one....
