The invention discloses lifting equipment, a speed limiting device and a triggering mechanism. The triggering mechanism comprises a first magnetic pole, a second magnetic pole, a conductive part, a transmission unit and a coil, the second magnetic pole and the first magnetic pole are separated and arranged to form a magnetic field, the conductive part is movably arranged, and the conductive part comprises a first end and a second end; the transmission unit comprises a connecting part used for being in fixed transmission connection with a rotating shaft and is used for driving the conductive part to cut the magnetic field, or the transmission unit is used for driving the first magnetic pole and the second magnetic pole to move and cutting the magnetic field by the conductive part; and the coil comprises a first wiring end electrically connected with the first end and a second wiring end electrically connected with the second end. The triggering mechanism can directly utilize the runningspeed of a lift car to carry out triggering control, and the sensitivity is higher. The triggering mechanism is adopted in the speed limiting device, the number of transmission parts is small, and the sensitivity is further improved under the condition that the reliability is guaranteed. A speed limiter is applied to the lifting equipment, so that the operation safety of the lift car is favorablyimproved.

    本发明公开了一种升降设备、限速装置及触发机构,该触发机构包括:第一磁极、第二磁极、导电件、传动单元及线圈,第二磁极与第一磁极间隔设置形成磁场,导电件可动设置,导电件包括第一端及第二端;传动单元包括用于与转轴固定传动连接的连接部,传动单元用于带动导电件切割磁场,或传动单元用于带动第一磁极及第二磁极运动、并使磁场被导电件切割;线圈包括与第一端电连接的第一接线端、以及与第二端电连接的第二接线端。该触发机构能够直接利用轿厢运行速度来进行触发控制,灵敏性更高。该限速装置采用了该触发机构,传动零件少,有利于保证可靠性的情况下,进一步提高灵敏性。该升降设备应用了该限速器,有利于提高轿厢运行的安全性。
