The invention provides a safety tongs system of an elevator speed governor. The safety tongs system comprises a speed governor steel wire rope; the lift car safety tongs are arranged on a lift car of the elevator and connected with the first end of the speed limiter steel wire rope; the counterweight safety tongs are arranged on a counterweight of the elevator and are connected with the second end of the speed limiter steel wire rope; the bidirectional speed governor is combined with the speed governor steel wire rope so as to detect the moving speed of the speed governor steel wire rope; the telescopic mechanism is mounted on the fixed structure; and the floating wheel set is rotatably installed on the telescopic mechanism, and the floating wheel set is suitable for tensioning the speed limiter steel wire rope through the elastic force of the telescopic mechanism so as to compensate the influence of the length extension of the speed limiter steel wire rope on the tensioning force. The bidirectional speed governor is arranged between the lift car and the counterweight to control the safety tongs on the lift car and the counterweight, so that part of parts are omitted, the total occupied space of a shaft is reduced, the tensioning force can be automatically adjusted according to the length of a rope, and the overall stability is improved.

    本公开提供了一种电梯限速器安全钳系统,包括:限速器钢丝绳;轿厢安全钳,设置在电梯的轿厢上,并连接所述限速器钢丝绳的第一端;对重安全钳,设置在电梯的对重上,并连接所述限速器钢丝绳的第二端;双向限速器,与所述限速器钢丝绳结合,以检测所述限速器钢丝绳的移动速度;伸缩机构,安装在固定结构上;以及浮动轮组,可转动地安装在所述伸缩机构上,所述浮动轮组适用于利用所述伸缩机构的弹力张紧所述限速器钢丝绳,以补偿所述限速器钢丝绳的长度伸长对张紧力的影响。通过在轿厢和对重之间设置一个双向限速器对轿厢和对重上的安全钳进行控制,省去了部分零部件,减少了井道的总占用空间,能够根据绳长自动调节张紧力,提高了总体稳定性。
