The invention discloses a sling lengthening device of hoisting machinery and a lengthening method of the sling lengthening device. The sling lengthening device comprises a supporting box; the fixed pulley is rotatably mounted in the supporting box; the cable winding shaft is rotatably mounted in the supporting box and is arranged below the fixed pulley; the movable pulley is movably arranged below the cable winding shaft, and a wheel shaft of the movable pulley is connected with a lower lifting lug; one end of the adjusting cable is wound on the cable winding shaft, the middle of the adjusting cable is wound on the fixed pulley and the movable pulley, and the other end of the adjusting cable is wound on the cable winding shaft; the driving structure comprises a driven gear, a driving gear and retaining teeth, the driven gear is coaxially connected to the cable winding shaft, the driving gear is rotatably installed outside the supporting box and meshed with the driven gear, the tooth root end of the retaining teeth is connected with a pivot, the pivot is rotatably installed outside the supporting box, and the pivot is provided with a torsional spring. The problems that in the construction process of super high-rise and tall buildings, the length of a steel wire rope of hoisting equipment needs to be adjusted through cooperation of multiple types of work, and the hoisting efficiency is low are solved.

    本发明公开了一种吊装机械的吊索加长装置及其加长方法,包括:支承箱;定滑轮,可转动安装于支承箱内;卷索轴,可转动地安装于支承箱内且设置于定滑轮的下方;动滑轮,可活动地设置于卷索轴的下方,动滑轮的轮轴连接有下吊耳;调节索,调节索的一端缠绕于卷索轴,调节索的中部缠绕于定滑轮和动滑轮,调节索的另一端缠绕于卷索轴;驱动结构,包括从动齿轮、主动齿轮和止退齿,从动齿轮同轴连接于卷索轴,主动齿轮可转动地安装于支承箱的外部且啮合于从动齿轮,止退齿的齿根端连接有枢轴,枢轴可转动地安装于支承箱的外部,枢轴安装有扭簧。本发明解决了在超高层和高大建筑施工过程中,吊装设备的钢丝绳调节长度需要多工种配合,吊装效率低的问题。
