The invention discloses a freight elevator door opening releveling protection method, which is characterized in that a weighing sensor is additionally arranged at the bottom of a lift car, the weighing sensor is in signal connection with a first signal input end of an elevator control cabinet, the weighing sensor is used for collecting the load capacity of the lift car and judging whether the lift car is overloaded or not according to a signal of the weighing sensor, and an encoder is arranged on a traction machine and is used for detecting whether the lift car is overloaded or not. The encoder is in signal connection with the second signal input end of the elevator control cabinet, whether the running direction of the lift car is ascending or descending is judged according to signals of the encoder, and the signal output end of the elevator control cabinet is in signal connection with the upper leveling switch, the upper releveling switch, the lower releveling switch, the lower leveling switch and the light curtain sensor. The weighing sensor is additionally arranged at the bottom of the lift car to collect the load capacity of the lift car, and the encoder is arranged on the traction machine to judge the state of the lift car, so that door-opening releveling operation is performed, and door-opening releveling protection of the freight elevator is realized.
本发明公开一种载货电梯开门再平层保护方法,在轿厢的底部增设称重传感器,该称重传感器与电梯控制柜的第一信号输入端信号连接,所述称重传感器用于采集轿厢载重量,根据称重传感器的信号判断是否超载,在曳引机上设置编码器,该编码器与电梯控制柜的第二信号输入端信号连接,根据编码器的信号判断轿厢的运行方向为上行还是下行,所述电梯控制柜的信号输出端分别与上平层开关、上再平层开关、下再平层开关、下平层开关、光幕传感器信号连接。本发明通过在轿厢的底部增加称重传感器来采集轿厢载重量,在曳引机上设置编码器来判定轿厢的状态,从而进行开门再平层运行,实现了对载货电梯的开门再平层保护。
