| 2.非人为因素引起的顶闸事故 2. Head Gate Accident Caused by Non-Human Factors 闸门在运行过程中，树木等漂浮物或石块等障碍物被高速水流带到闸底或冲到闸槽中卡住，若此时关闭闸门，当闸门下缘在未接触到闸底之前已被障碍物阻挡产生反力，但螺杆上的限位标志或限位开关还没有到位，不起限位停机或提醒操作人员停机的作用，故操作人员不会停机，启闭机将带动闸门继续下压，当反力超过启闭机或启闭台的承受耐力时，也必将发生顶闸事故。 During the operation of the gate, obstacles such as floating objects or stones, such as trees, are carried to the bottom of the gate by high-speed water flow or are blocked in the gate slot. If the gate is closed at this time, when the lower edge of the gate is blocked by obstacles before it touches the bottom of the gate, the reaction force is produced. However, the limit sign or limit switch on the screw has not been put in place, and the limit stop is not allowed. Operators will not stop because of the function of the machine or reminding the operator to stop. The hoist will drive the gate down. When the reaction force exceeds the endurance of the hoist or the hoist, the jacking accident will also occur. 在使用过程中，要尤为注意到螺杆式启闭机的顶闸事故问题，如果出现这种事故，要及时进行处理，以免导致更严重的事故发生。 In the course of using, we should pay special attention to the problem of the top brake accident of screw hoist. If this accident occurs, we should deal with it in time so as to avoid more serious accidents. |
