The invention belongs to the technical field of rail transit, and relates to a subway civil air defense moving contact net which comprises a first fixing frame, a second fixing frame and a supportingframe connected to the first fixing frame and the second fixing frame in a sliding mode, the first fixing frame and the second fixing frame are spaced, a busbar is arranged on one side of the supporting frame, and a walking mechanism is arranged on the other side of the supporting frame. The walking mechanism can drive the supporting frame to move front and back, so that the supporting frame is connected with the first fixing frame and the second fixing frame or disconnected with the first fixing frame and the second fixing frame, and the walking mechanism comprises at least two driving motorsinstalled on the supporting frame. And a gear engaged with a rack on the first fixing frame is arranged on an output shaft of the driving motor. The subway civil air defense moving contact net has the advantages of being simple in structure, convenient to operate, stable, reliable, high in positioning precision and the like, the contact net can be temporarily disconnected before a civil air defense door is emergently closed, the contact net can be rapidly connected after recovery, personnel do not need to enter a tunnel in an adventure mode, and the safety performance is greatly improved.
本发明属于轨道交通技术领域,涉及一种地铁人防移动接触网,包括间隔设置的第一固定架和第二固定架,以及滑动连接在第一固定架和第二固定架上的支撑架,所述支撑架一侧设有汇流排,另一侧设有行走机构,所述行走机构能够驱动支撑架进行前后移动,从而实现支撑架连接第一固定架和第二固定架,或断开第一固定架和第二固定架之间的连接,所述行走机构包括安装在支撑架上的至少两个驱动电机,所述驱动电机输出轴上设有与第一固定架上齿条相啮合的齿轮。本发明具有结构简单,操作方便,稳定可靠,定位精度高等优点,能够在人防门紧急关闭前将接触网临时断开,并能够在恢复后快速将接触网连接上,无需人员冒险进入隧道内,大大提高了安全性能。
