Elevator landing unlocking device
The invention discloses an elevator landing unlocking device. The elevator landing unlocking device comprises a pull rope, an unlocking lever, a middle linkage mechanism, a reset spring and a lock cylinder mechanism, wherein the upper end of the pull rope is located above a landing door, and the lower end of the pull rope is located in the middle or the lower portion of the side face of the landing door; one end of the unlocking lever is installed on a rotating latch hook, the other end of the unlocking lever is suspended and fixed to the upper end of the pull rope, and the two ends of the unlocking lever are located on the two sides of the rotating center of the rotating latch hook correspondingly; the middle linkage mechanism comprises a middle connecting seat and a rotary deflector rod,the middle connecting seat is installed on the side face of the landing door, the rotary deflector rod is rotatably installed on the middle connecting seat, and the lower end of the pull rope is fixed to the rotary deflector rod; one end of the reset spring is installed on the middle connecting seat, and the other end of the reset spring is installed on the rotary deflector rod; the lock cylindermechanism is installed on a side sleeve on the side edge of a door pocket and is used for driving the rotary deflector rod to rotate. According to the elevator landing unlocking device, the middle linkage mechanism is additionally arranged in the middle or the lower portion of the side face of the landing door and provided with the spring for resetting, so that a movable landing door lock can beunlocked through the lock cylinder arranged on the static door pocket, and the accident that the landing door lock is prone to falling into a shaftway during maintenance is avoided.
本发明公开了一种电梯层站解锁装置，包括：拉绳，上端位于层门上方，下端位于层门的侧面中部或下部；解锁杠杆，一端安装在转动锁钩上，另一端悬空并与拉绳上端固定，解锁杠杆的两端分别位于转动锁钩的旋转中心的两侧；中间联动机构，包括中间连接座和旋转拨杆，中间连接座安装在层门的侧面上，旋转拨杆转动安装在中间连接座上，拉绳的下端与旋转拨杆固定；复位弹簧，一端安装在中间连接座上，另一端安装在旋转拨杆上；锁芯机构，安装在门套的侧边旁套上，用于驱使所述旋转拨杆转动。本发明在层门侧面中部或下部增加了中间联动机构且带弹簧复位，使移动的层门锁可以设于静止的门套上的锁芯解锁，避免了维修时容易发生跌落井道的事故。
