Provided are a pulley mechanism having a self-protection function for an elevator and an elevator, the pulley mechanism having a self-protection function for an elevator comprising: an axle mechanism comprising a pulley and a central shaft assembled coaxially with each other; the pulley and the central shaft are movably assembled through the first-stage bearing, and the first-stage bearing enables the pulley and the central shaft to have relative rotational degrees of freedom; the central shaft is assembled with the beam frame through the second-stage bearing, and the second-stage bearing enables the central shaft and the beam frame to have relative rotational degrees of freedom; the brake mechanism can limit the rotational degree of freedom between the central shaft and the beam frame; and when the relative rotational degree of freedom between the pulley and the central shaft cannot be realized by means of the first-stage bearing, the brake mechanism is separated from the central shaft, and the central shaft has the relative rotational degree of freedom with the beam frame by means of the second-stage bearing. In this way, the second-stage bearing can participate in rotation when necessary, and safety is guaranteed.
提供了电梯用具备自我保护功能的滑轮机构及电梯,电梯用具备自我保护功能的滑轮机构包括:轮轴机构,包括相互同轴装配的滑轮和中心轴;一级轴承,滑轮与中心轴之间通过一级轴承活动装配,一级轴承使滑轮与中心轴之间具备相对的旋转自由度;二级轴承,中心轴通过二级轴承与梁架装配,二级轴承使中心轴与梁架之间具备相对的旋转自由度;刹车机构,刹车机构能够限制中心轴与梁架之间的旋转自由度;其中,当滑轮与中心轴之间无法借助一级轴承实现相对的旋转自由度时,刹车机构与中心轴脱离,并使中心轴借助二级轴承与梁架之间具备相对的旋转自由度。这样必要时二级轴承可以参与旋转,保证安全性。
