The elevator rope unwinding device comprises a winding rope, a retaining device, a second support, a first rope winding wheel, a second rope winding wheel and a driving device, the retaining device comprises a first support and a plurality of rope pressing wheels, each rope pressing wheel is arranged on the first support, and a gap allowing the winding rope to penetrate out is reserved between every two rope pressing wheels; the first rope winding wheel is arranged on the second bracket; the second rope winding wheel can be rotationally arranged on the second bracket around the axis of the second rope winding wheel; the driving device is used for driving the first rope winding wheel and the second rope winding wheel to rotate; one end of the winding rope is connected with the rope storage reel, and the other end of the winding rope penetrates through the gap and repeatedly winds around the first rope winding wheel and the second rope winding wheel by at least two circles. Therefore, the rope pressing wheel in the retaining device presses the winding rope to generate certain positive pressure, the winding rope is repeatedly rewound through the first rope winding wheel and the second rope winding wheel to increase the wrap angle, the stress ratio of the two ends of the winding rope is increased, and the winding rope can be better released.

    本申请涉及一种电梯放绳器及电梯,本申请的电梯放绳器包括:绕绳、保持装置、第二支架、第一绕绳轮、第二绕绳轮和驱动装置,保持装置包括第一支架以及多个压绳轮,每个压绳轮设于第一支架上,每两个压绳轮之间留有供绕绳穿出的间隙;第一绕绳轮设于第二支架上;第二绕绳轮能绕自身轴线转动地设于第二支架上;驱动装置用于驱动第一绕绳轮和第二绕绳轮转动;其中,绕绳一端连接储绳卷盘,另一端穿过间隙且重复绕过第一绕绳轮和第二绕绳轮至少两圈。故本申请通过保持装置中压绳轮对绕绳压紧产生一定的正压力,并通过第一绕绳轮和第二绕绳轮对绕绳进行重复复绕以增大包角,增大绕绳两端的受力比值,从而能够更好地释放绕绳。
