一种用于杂物电梯的防剪切保护装置的设计

Design of Anti-shearing Protection Device for Service Lift

杂物电梯广泛应用于饭店的食物运送和医院、图书馆、银行等部门的小件货物运送,而杂物电梯导致的人员伤亡事故也时有发生,且大多与门系统有关。为确保杂物电梯即使在层门开启情况下依然不会发生剪切事故,开发了一套防剪切保护装置。该保护装置能够在杂物电梯层门安全装置失灵的情况下,有效地保护人员安全;具有故障锁定功能,消除了杂物电梯发生剪切事件后继续运行的安全隐患;结构简单可靠,不仅适合作为新安装杂物电梯的标准配置,也适合在已使用的杂物电梯上进行加装。该防剪切保护装置对提升杂物电梯安全运行、保障使用人员安全具有积极的推动作用。

The service lifts are widely used in food transportation of hotels and small goods transportation of hospitals,libraries,banks and other departments.Accidents caused by service lifts also occur from time to time,and most of them are related to the door system.In order to ensure that the service lift will not shear the user even when the hall door is opening,a set of anti-shearing protection device is developed.The protection device can effectively protect the safety of users when the door safety device of the service lift is out of order.The device has the function of fault locking,which eliminates the potential safety hazard of the service lift after the shearing event.The structure of the device is simple and reliable,which is not only suitable for the standard configuration of the new service lift,but also can be installed on the old service lift.The anti-shearing protection device has a positive role in promoting the safety of both service lifts and users.
