The invention relates to an elevator 125% load test method. The method comprises the following steps that 1) a distance and speed measurement radar sensor is mounted at the top of an elevator shaft, and an incremental rotary encoder is mounted on a traction sheave of an elevator; the distance and speed measurement radar sensor, the incremental rotary encoder and a red-green double-color prompt lamp are respectively connected with an upper computer; 2) a weight block is arranged in an elevator car; 3) a distance parameter S0 between the top of the elevator car and the distance and speed measurement radar sensor is detected; 4) when the elevator car descends to the rated speed V0, the power supply of a motor and a brake of an elevator is cut off; 5) after the elevator car is stopped, a distance parameter S1 between the bottom of the elevator car and the distance and speed measurement radar sensor is detected; the upper computer calculates the descending distance S of the elevator car and the unwinding length L of a steel wire rope on the traction wheel; and 6) if the upper computer calculates that the sliding distance delta L of the steel wire rope on the traction wheel is greater than 0, the steel wire rope on the traction wheel slides. Whether the steel wire rope slips on the traction wheel or not can be detected.

    本发明涉及一种电梯125%载荷试验方法,包括以下步骤:1)在电梯井顶部安装测距测速雷达传感器,在电梯的曳引轮上设置增量式旋转编码器;速雷达传感器、增量式旋转编码器及红绿双色提示灯分别与上位机连接;2)在电梯轿厢内配置重量块;3)检测电梯轿厢顶部与测速测距雷达传感器的距离参数S0;4)当电梯轿厢下降达到额定速度V0,切断电梯的电动机和制动器供电;5)电梯轿厢停止后,检测电梯轿厢底部与测速测距雷达传感器的距离参数S1;上位机计算电梯轿厢的下降距离S和曳引轮上钢丝绳放出的长度L;6)上位机计算曳引轮上钢丝绳的滑行距离ΔL>0,则曳引轮上钢丝绳发生滑行。本发明可检测钢丝绳有无在曳引轮上发生打滑。
