双层罐笼提升摆折式安全门的设计

Design of Hoisting Pendulum Folding Safety Door of Double Cage

根据双层罐笼提升系统中井口高度空间较低的状况,研究设计了一种摆折式新型安全门,介绍了摆折式新型安全门的结构特点、工作原理及主要技术参数,对安全门的强度进行计算,该安全门经现场使用表明,动作灵活,安全可靠,符合《煤矿安全规程》的具体要求,效果良好。

According to the status of the low wellhead height space in the double cage hoisting system, this paper researches and designs a new pendulum folding safety door, introduces structural characteristics ,working principle and main technical parameters of the new pendulum folding safety door,and calculates the strength of the door, the field use shows that the door has such characteristics as flexible movement, safe and reliable,complies with the specific requirements of the ＂Coal Mine safety Regulations＂, and the effect is good.
