The invention discloses an elevator landing door system which comprises a landing door, an upper sill frame, a landing door sill and a heating device, the heating device is installed on the lower portion of a landing door sill groove, and the elevator landing door system further comprises a door closing in-place switch; when the door closing in-place switch does not detect that the landing door is closed in place, the heating device is controlled to heat; and when the door closing in-place switch detects that the landing door is closed in place, the heating device is controlled to stop heating. According to the invention, the moist environment of a local space near the door sliding block is improved, and an adhesion state is avoided; the heating time can be ingeniously controlled, and aging of the door sliding block caused by long-time overhigh local temperature is avoided; meanwhile, invalid heating when the door sliding block does not work can be avoided, and energy consumption is greatly reduced.
本发明公开了一种电梯层门系统,包括层门、上坎架、层门地坎和加热装置,所述加热装置安装在层门地坎槽的下部,所述电梯层门系统还包括关门到位开关;当所述关门到位开关未检测到层门关门到位,控制加热装置进行加热;当所述关门到位开关检测到层门关门到位后,控制加热装置停止加热。本发明既实现了对门滑块附近局部空间潮湿环境的改善,避免引起黏着态;又能巧妙的控制加热时间,避免局部温度长时间过高,引起门滑块老化;同时能避免门滑块不工作时的无效加热,大大降低能耗。
