【技术实现步骤摘要】
一种用于高速消防梯的轿顶安全窗
本专利技术属于电梯
,涉及一种用于高速消防梯的轿顶安全窗。
技术介绍
消防电梯需要在轿顶开设安全窗口,而高速消防电梯为了降低风阻和实现轿顶双层隔音,一般采用双层轿顶,分上下两层。为了满足国标要求,上下两层都应开安全窗口,尺寸必须满足国标最小要求。如图1所示,因上下层轿顶之间空间限制,现有的轿顶安全窗只能安装在上层轿顶上,下层轿顶上的安全窗口无法关闭,且不美观。同时,双层轿顶结构失去隔音作用:上层轿顶传来的噪音直接进入轿厢,轿厢内噪音较大,舒适感较低。
技术实现思路
本专利技术所要解决的技术问题是提供一种结构简单、可同时关闭双层轿顶上下层安全窗口的轿顶安全窗。为解决上述问题,本专利技术是通过以下技术方案实现的:一种用于高速消防梯的轿顶安全窗,所述高速消防梯的上层轿顶和下层轿顶均开有安全窗口,上层轿顶上方沿其安全窗口设有一圈向上凸起的安装方框;所述轿顶安全窗包括:与所述安装方框铰接并可绕铰接点翻转的窗框、与所述窗框固定连接并与所述上层轿顶的安全窗口匹配的上窗盖、以及与所述上窗盖固定连接并与所述下层轿顶的安全窗口匹配的下窗盖。进一步地, ...
