The invention provides a method and device for rapidly detecting traction force of a steel wire rope traction driving elevator, and belongs to the technical field of elevators. Under the no-load condition, whether the traction force is insufficient or not is judged according to the slippage distance of the steel wire rope under the elevator running condition and the elevator running height difference, if the traction force exceeds the preset threshold value, the traction force is insufficient, and if the traction force is smaller than or equal to the preset threshold value, the traction force is reliable. The method can be carried out under the normal operation condition of the elevator, and the elevator does not have the top rushing or bottom heading risk; the device is not limited by the height of the elevator and is also suitable for elevators in low-layer stations; extra tools are not needed, a large number of weights do not need to be prepared, and manpower and time are saved.
本发明提供了一种钢丝绳曳引驱动电梯曳引力快速检测方法及装置,属于电梯技术领域。本发明在空载情况下,通过电梯运行下的钢丝绳滑移距离和电梯运行高度差判断曳引力是否不足,如果超过预设阈值,则曳引力不足,如果小于等于预设阈值,则曳引力可靠。本发明能够在电梯正常运行情况下进行的,电梯没有冲顶或墩底风险;不受电梯高度限制,对于低层站的电梯同样适用;不需要额外的工具,更不需要准备大量砝码,节省人力和时间。
