Design and Research of Hoisting Safety Door Opening and Closing Device

安全门是防空、防灾设施出入口的一种安全防护设施,当出现水灾、毒气等灾害时,安全门关闭,保护人民的生命财产安全。因此,设计了一种双出绳双吊点电动葫芦式提升安全门启闭装置。这种装置便于检测维修,在断电情况下可以关闭和开启安全门,使安全门具有安全应急处理功能。

The safety door is a kind of safety protection facility at the entrance and exit of air defense and disaster prevention facilities.In case of flood,gas and other disasters,the safety door is closed to protect people’s life and property.In this paper,a double rope and double lifting point electric hoist type safety door opening and closing device is designed.This device is convenient for inspection and maintenance.It can close and open the safety door in case of power failure,so that the safety door has safety emergency treatment measures.
