The invention discloses an unhooking rope clip which comprises a main shaft, an inner clip, an outer clip and an elastic component. A first operation wheel is arranged at one end of the main shaft, and a damping component used for being connected with a lifting compartment is arranged between the two ends of the main shaft. And the inner holding clamp is connected to the other end of the main shaft. One end of the outer holding clamp is rotatably connected with the inner holding clamp so as to clamp or release the steel wire rope, and the other end of the outer holding clamp is provided with a second operation wheel. The elastic component is arranged between the outer holding clamp and the inner holding clamp, the two ends of the elastic component abut against the outer holding clamp and the inner holding clamp respectively, the elastic component comprises at least two spiral springs with different inner diameters, and the spiral springs are arranged in an inner-outer nested mode. The elastic component of the unhooking rope clip is formed by nesting the at least two spiral springs inside and outside, the spiral springs jointly bear loads, the stress of a single spring is reduced to about 60% of that of the previous spring, domestic materials meet the service life requirement, and cost is effectively reduced.

    本发明公开一种脱挂抱索器,包括主轴、内抱卡、外抱卡和弹性部件。所述主轴的一端设有第一操作轮,所述主轴的两端之间设有用于连接吊厢的减震部件。所述内抱卡连接在所述主轴的另一端。所述外抱卡的一端和所述内抱卡可转动地连接,以夹持或释放钢丝绳索,所述外抱卡的另一端设有第二操作轮。所述弹性部件设置在所述外抱卡和所述内抱卡之间,所述弹性部件两端分别抵顶在所述外抱卡和所述所述内抱卡上,所述弹性部件包括至少两个内径不同的螺旋弹簧,各所述螺旋弹簧内外嵌套设置。本发明的脱挂抱索器的弹性部件为至少两个螺旋弹簧内外嵌套形成,各螺旋弹簧共同承担负载,单根弹簧受力减小为先前的百分之六十左右,使得国内材料满足寿命要求,有效地降低了成本。
