Crane wire rope replacement method

Abstract

The invention discloses a replacement method of a steel wire rope of a crane. The replacement method comprises the steps that an old steel wire rope is cut off, and the distance between the cutoff position and the center of the old steel wire rope is X; two rope ends of a new steel wire rope are connected with two rope ends obtained after cutoff correspondingly, and the length of the new steel wire rope is equal to the sum of the length of the old steel wire rope and 2X; press plates on a winding drum are dismounted, the winding drum is rotated, and the old steel wire rope is driven to move; when X=0, two joints rotate to the winding drum at the same time, and the winding drum stops rotating at this moment; when X is not equal to 0, when the front joint arrives at the winding drum, the winding drum continues to rotate, and the winding drum stops rotating till the back joint arrives at the winding drum; the two synchronously-arriving joints are cut off; or, the back joint is cut off, and the new steel wire rope is cut off at the same position of the other end of the winding drum; the press plates are adopted for fixing the cutoff rope ends to the winding drum; and the winding drum continues to rotate till the preset number of circles of winding is achieved. According to the replacement method of the steel wire rope of the crane, the time used for replacement is short, labor intensity is reduced, and work efficiency is improved.

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] After the steel wire rope of the crane has been used for a period of time, due to various reasons, the steel wire rope is prone to torsional force. The use of cranes is safe. Therefore, the steel wire rope needs to be replaced after a period of use. [0003] In the prior art, when the steel wire rope of a crane is installed, the steel wire rope is an independent steel wire rope. When the steel wire rope is wound, one end of the steel wire rope is fixed on the reel by the first pressure plate, and the steel wire rope is wound on the reel, and then passes through the moving Set the first movable pulley on the same side as the first pressure plate in the pulley block, the first fixed pulley on the same side of the fixed pulley block and the second movable pulley in the movable pu...

Problems solved by technology

Since the wire rope is relatively thick, more than four people are required to pull it out, which is labor intensive and inefficient.
