Abstract
Combined with Jinfeng Reservoir Project of the Wudu Water Diversion Phase Ⅱ,this paper introduces the situation where the lifting mechanism of the 1 X 400 kN-35 m two-way gantry crane reverses the rotation direction of the winding rope groove,resulting in the interference between steel wire rope and the edge of hy-draulic lifting hole when the movable pulley was lowered due to the winding of the wire rope,for which the steel wire rope roller device under the drum was added to reduce the distance between upper and lower steel wire ropes.After the on-site treatment was carried out according to the remediation plan,the distance between the steel wire rope on the opening and closing motorized pulley was forcibly reduced,and the steel wire rope no longer interfered with the edge of the lifting hole after the moving pulley entered the lifting hole,the lifting load capacity of the lifting mechanism was not affected,and the lifting operated normally.It has been proved by op-eration that the steel wire rope roller with guide wheels can limit the space opening of steel wire rope.This de-sign principle can be used as reference in engineering construction where the position of steel wire rope needs to be adjusted or controlled.关键词
