The invention discloses an elevator retention working condition detection device which comprises a lift car side displacement detection device, a counterweight side displacement detection device, a traction sheave rotation displacement device and a retention working condition judgment unit. The retention working condition judging unit is used for collecting the lift car displacement, the counterweight displacement and the rotation displacement of the traction wheel; the retention working condition judging unit converts the rotation displacement of the traction wheel into a lift car displacement calculation value, the lift car displacement calculation value is compared with the lift car displacement and the counterweight displacement, and when the difference value of the lift car displacement and the lift car displacement calculation value is larger than a first threshold value, it is judged that the lift car is retained; and when the difference value between the calculated value of the counterweight displacement and the calculated value of the lift car displacement is larger than a second threshold value, it is judged that the counterweight is detained, and the operation stopping instruction is sent to the elevator control system. The device can effectively detect the retention working condition of the lift car or the counterweight, saves materials, and reduces the energy consumption of the elevator.
本发明公开了一种电梯滞留工况检测装置,包括:轿厢侧位移检测装置,对重侧位移检测装置、曳引轮旋转位移装置和滞留工况判断单元;所述滞留工况判断单元采集所述轿厢位移、所述对重位移和所述曳引轮的旋转位移;所述滞留工况判断单元将所述曳引轮的旋转位移折算成轿厢位移计算值,将所述轿厢位移计算值分别和所述轿厢位移与所述对重位移进行比较,当所述轿厢位移和所述轿厢位移计算值的差值大于第一阈值时判定轿厢滞留,向电梯控制系统发出停止运行的指令,当所述对重位移和所述轿厢位移计算值的差值大于第二阈值时判定对重滞留,向电梯控制系统发出停止运行的指令。本发明能有效检测轿厢或对重的滞留工况,节约材料,降低电梯能耗。
