The invention discloses an elevator rope extension detection device and method and an elevator. The elevator rope is connected with a rope head device and an operation device in an elevator, and the elevator rope elongation detection device comprises one or more supports connected with an elastic reset component in the rope head device; the connecting piece is connected with at least one support in the supports, and the connecting piece is arranged to be driven by the at least one support to enter a triggering position when the displacement of the elastic reset component exceeds a threshold value due to reduction of the compression amount; and the triggering piece is connected with the connecting piece and is arranged to be triggered to generate a triggering signal when the connecting piece enters the triggering position. The method can be widely applied to detection of elevator rope extension conditions in a plurality of elevator devices.

    本发明公开了电梯绳索伸长检测装置和检测方法以及电梯。所述电梯绳索与电梯中的绳头装置和运行装置相连,所述电梯绳索伸长检测装置包括:一个或多个支架,其与所述绳头装置中的弹性复位部件相连;联接件,其与所述支架中的至少一个支架相连,并设置成在所述弹性复位部件由于压缩量减小而发生位移超过阈值时,所述联接件被所述至少一个支架带动进入触发位置;触发件,其与所述联接件相连,并设置成在所述联接件进入所述触发位置时被触发而产生触发信号。本发明可以广泛应用于检测众多电梯设备中的电梯绳索伸长状况。
