The invention discloses lifting equipment, a safety device and a limiting mechanism. The limiting mechanism comprises a mounting piece, a limiting piece and a transmission piece; the limiting piece ismovably arranged on the mounting piece, and is provided with a first limiting part for limiting the rotation or reverse rotation of a rope wheel; the transmission piece is provided with a connectingpart for transmission connection with a limiter, and a matching body arranged at intervals the connecting part; when the transmission piece is located in a first position, the matching body is matchedwith the limiting piece, so that the first limiting part is staggered with the rope wheel; and when the transmission piece is located in a second position, the matching body is staggered with the limiting piece, and the first limiting part is in stop fit with the rope wheel. The limiting mechanism can prevent the rotation or reverse rotation of the rope wheel to prevent abnormal reset of the limiter. The safety device adopts the limiting mechanism to prevent abnormal reset of the limiter, so that the operation safety of the lifting equipment is improved. The lifting equipment adopts the safety device to achieve higher safety and to improve the operation reliability of the lifting equipment.

    本发明公开了一种升降设备、安全装置及限位机构,该限位机构包括:安装件、限位件及传动件,限位件可动设置于安装件上,限位件设有用于限制绳轮转动或反转的第一限位部,传动件设有用于与限位器传动连接的连接部、以及与连接部间隔设置的配合体;当传动件处于第一位置时,配合体与限位件相配合,使得第一限位部与绳轮相错开;当传动件处于第二位置时,配合体与限位件相错开,第一限位部与绳轮止动配合。该限位机构能够防止绳轮转动或反转,进而可避免限速器异常复位。该安全装置采用了限位机构,能够避免限速器异常复位,有利于提高升降设备运行的安全性。该升降设备采用了该安全装置,安全性更高,有利于提高升降设备运行的可靠性。
