Abstract

深窄井救生捞具，包括主杆、摇杆、护网以及弹性铰链、滚轮和锁扣，摇杆用弹性铰链连接在主杆的头部四周，摇杆之间用护网连接，使用时先将摇杆合拢紧靠主杆，用锁扣锁定在主杆的锁孔中，摇杆与主杆成平行状态，把捞具的头部伸入落井者的下方，释放锁扣，摇杆打开与主杆成直角，同时护网张开形成一个网架式的救援平台，然后向上慢慢提升主杆，就能将落井者救出，从而为施救人员提供一种方便、快捷的简易施救工具。

Description

深窄井救生捞具
技术领域
本发明涉及一种井下救生装置，具体地说是一种抢救落入深窄井人员的救援工具。
背景技术
现今，马路窨井和农民浇地用的水井众多，经常有人掉人井中，在电视里常见消防人员前去抢救，由于这种井口径较小，只能容一个人上下，在抢救那些老小和神志迷糊的人员时，救生索工具下去后，他们不知道如何捆绑，救援人员下去后又由于井口太小，不能在同一个平面去帮助他，只好通过无数次地大声讲解，才能勉强帮扎，有时候帮扎不正确或者捆绑不实，在起吊过程中又有掉下去的危险，这样不但浪费时间，还会给被救者造成巨大的心理压力，对继续施救及为不利。
发明内容
为了克服现有的救生索具不适用救援落入深窄井者的不足，本发明提供一种深窄井救生捞具，该捞具不需专业的捆绑技术，也不用施救人员下井，只要将该捞具伸入被救者的下方，打开头部的网架结构，就能将落井者救出井中。
本发明解决其技术问题所采取的技术措施是，捞具由主杆、摇杆、护网以及滚轮和锁扣拉绳等组成，主杆制成中空多节，用螺纹连接，其头部制成球状，球状的直径大于主杆直径，头部与主杆的接头处形成一个圆周形的平台，在所述的平台上的四周用弹性铰链连接摇杆，摇杆制成弹性伸缩节，其头部安装滚轮，各摇杆之间用护网连接，所述摇杆的前端固定一个具有弹性的锁扣，主杆上与锁扣相对应的位置开锁孔，当锁扣插入锁孔时，能克服弹性铰链的力将摇杆与主杆固定在平行状态。在主杆内锁孔的下方设置一滑块，滑块下面连接拉簧，滑块上面的中心连接拉绳，拉绳向上伸出主杆，拉绳上端连接小金属球，接杆时便于引导拉绳穿过主杆内孔，在自由状态下，滑块在主杆锁扣的下方，当拉动拉绳时，滑块向上，同时顶起锁扣使其释放，在摇杆弹性铰链的作用下，摇杆打开与主杆成直角状态，同时带动护网张开，形成一个网架结构的施救平台。使用时，把摇杆收拢的捞具伸入落井者的下方，向上拉拉绳，使摇杆打开，当确认落井者已处在捞具的施救平台上时，就可以向上提升主杆，如果向上提主杆时碰到井壁，安装在摇杆头部的滚轮能起导向作用，以防卡死。有的井口向上逐小，摇杆的弹性伸缩会随着井口直径的变化而伸缩，这样就能达到快捷、安全地救出落井者的目的。
本发明的有益效果是，为施救人员抢救落入深窄井人员提供一种方便、安全的施救工具，结构简单。
附图说明
下面结合附图对发明作进一步说明。
图1是深窄井救生捞具的结构示意图。
图2深窄井救生捞具的锁扣装置示意图。
图3深窄井救生捞具打开时的状态图。
图中，1、头部，2、弹性铰链，3、摇杆，4、滚轮，5、主杆，6、拉绳，7、护网，8、锁孔，9、锁扣，10、滑块，11、拉簧，12、金属球。
具体实施方式
在图1和图2中，主杆5制成多节用螺纹连接，其头部1制成球形，头部的直径大于主杆直径，连接处形成一个圆周形平台，在所述平台上用弹性铰链2连接摇杆3，摇杆制弹性伸缩节，其头部安装滚轮4和锁扣9，主杆与锁扣相对应的位置开锁孔8，拉绳6伸入主杆内连接主杆内的滑块，当摇杆向主杆靠拢时锁扣9插入主杆的锁孔8中，锁住摇杆，使摇杆与主杆平行，在锁孔的下方设置滑块10，滑块的下面连接拉簧11，滑块的上面连接拉绳6，当向上提升拉绳时，滑块向上顶起锁扣，使锁扣释放，摇杆在弹性铰链的作用下打开，通常拉绳上端连接金属球12，该金属球小于主杆内孔，便于接杆时引导拉绳穿过主杆内孔。
图3中，锁扣9释放后，摇杆打开与主杆成直角状态，连接在摇杆之间的护网7同时张开，形成一个网架式的施救平台。
