The invention relates to the technical field of elevator car safety protection, in particular to a car accidental movement protection device which comprises at least two side plates, a fixing plate, an ascending braking mechanism, a descending braking mechanism, a transmission component and a sensing component, and the two ends of the fixing plate are fixedly connected with the side plates correspondingly; the ascending braking mechanism and the descending braking mechanism are rotationally installed on the side plates correspondingly, and one end of the ascending braking mechanism and one end of the descending braking mechanism abut against the fixing plate correspondingly. The steel wire rope is located between the fixing plate and the ascending braking mechanism and/or the descending braking mechanism. One end of the transmission part is rotationally connected with the side plate, one end of the transmission part abuts against the ascending braking mechanism and/or the descending braking mechanism, and one end of the sensing part is close to the transmission part. By the adoption of the scheme, the problem that the braking speed is low due to the fact that the deceleration stroke of a brake of an existing lift car accidental movement protection device is long can be solved.

    本申请涉及电梯轿厢安全防护技术领域,尤其涉及一种轿厢意外移动保护装置,包括侧板、固定板、上行刹停机构、下行刹停机构、传动部件和感应部件,侧板至少设置有两块,固定板的两端分别与一块侧板固定连接;上行刹停机构和下行刹停机构分别转动安装于侧板上,上行刹停机构和下行刹停机构的一端分别与固定板抵接;钢丝绳位于固定板与上行刹停机构之间,和/或下行刹停机构之间;传动部件的一端与侧板转动连接,传动部件的一端与上行刹停机构抵接,和/或下行刹停机构抵接,感应部件的一端贴近传动部件。采用上述方案,能够改善现有的轿厢意外移动保护装置,其制动器的减速行程较长,导致其制动速度较慢的问题。
