Abstract

本实用新型公开了一种矿井防爆破冲击波风门,使用它可以防止被冲击波损坏。本实用新型有门框(2)、门扇(7),在门框(2)中设有凸形横梁(3),在凸形横梁(3)的上部空间设有正泄压窗(4)和反泄压窗(6),并用折页(5)将二者与门框(2)活动连接。这种风门主要用于矿井的通风系统。

Description

矿井防爆破冲击波风门
技术领域
本实用新型涉及一种矿井防爆破冲击波风门。
背景技术
目前,煤矿矿井的岩石掘进大多采用钻爆法施工,爆破时产生的冲击波对风门有很大损伤,有时导致风门变形,甚至损坏,严重影响矿井通风系统的正常运行。
发明内容
本实用新型要解决的技术问题是,提供一种矿井防爆破冲击波风门,它不会被爆破时产生的冲击波所损坏。
为解决上述技术问题,本实用新型有门框、门扇,在门框中设有凸形横梁,在凸形横梁的上部空间设有正泄压窗和反泄压窗,并用折页将二者与门框活动连接。
由于本实用新型自身设有泄压装置,爆破时产生的冲击波不会将其损坏,延长了风门的使用寿命,有效地保障了矿井通风系统的正常运行。
附图说明
图1是本实用新型的结构示意图;
图2是图1的A-A剖视图。
图中:门轴1、门框2、凸形横梁3、正泄压窗4、折页5、反泄压窗6、门扇7。
具体实施方式
由图1、图2可知:本实用新型有门框2、门扇7,在门框2中设有凸形横梁3,在凸形横梁3的上部空间设有正泄压窗4和反泄压窗6,并用折页5将二者与门框2活动连接,在门框2和门扇7之间设有门轴1。
使用本实用新型,由于正泄压窗4和反泄压窗6从图2中看有一定的垂直角度,它们是依靠自身的重力来关闭的,保证在正常时不漏风,当巷道施工爆破时,冲击波的压力大于泄压窗的重力分力时,自动将其打开泄压,如果来自门前的冲击波,则正泄压窗4打开泄压,反之,反泄压窗6打开泄压。
