Abstract

防坠落天梯,用于高层设施的工作梯,为了解决已有梯存在的坠落危险性问题,本发明采取的技术方案是:已有的梯增加框状围栏,围栏内每上4米设置一个门,若人上梯,可以边上梯边把身下门关上;若人下梯,边下梯边把门逐个打开。如此,这梯等于由大高度的高梯分割成了小高度的梯子,大大降低了上下梯的危险性。

Description

防坠落天梯
(一)技术领域:本发明涉及一种用于高层设施防坠落的工作梯,如用于塔吊、手机信号塔等。
(二)背景技术:目前所见到的塔吊等高层设施,其工作梯无防坠落设计,操作工上、下操作室,尤其是在天气不好的情况下,更有一定的危险性。
(三)发明内容:为了提高操作工上、下操作室安全性,本发明采取的技术方案是:以原已有梯为一边,以已有梯的左右和对面为另边做成有封闭的围护栏的工作梯,在围护栏内从上到下间设置可开关的门,如此,操作工上下操作室过程中,若要上去,可以在爬梯中把脚下的门一个一个关上;若要下去,可以把脚下的门一个一个打开,关上了门,等于把危险性大的梯大高度分割成多个危险性较小的小高度,这样能确保操作工上下操作室爬梯即使脚踩空掉下也不会造成重大事故。
(四)附图说明:附图为天梯中间部分示意图,图中:
1、与用梯设施结合端口,2、铁框,3、踏脚梯杠,4、粗直栏杆,5、细直栏杆,6、防坠门,7、门铰链,8、关门杠,9、踏脚梯杠。
(五)具体实施方式:实施例
以直径1.5cm钢筋作各边为70cm的,开口的正三边框,三边框两个角和两边距开口15cm处垂直固定四根直径1cm的大直栏杆,在框近端的两和大直栏杆固定处之间连接直径1.5cm的踏脚杠——其它铁框、栏杆,杠的连接皆是如此。各个相邻框间距40cm,在每对相邻两框踏脚杠之间再平行安一踏脚杠,使各相邻脚杠间距变成20cm。在梯三边(不包括踏脚杠边)从上到下垂直设置直径0.6cm的小直栏杆,间隔为13cm左右,以人不掉出为准,结合在框上。在梯每4米高度处设一个可向上开防坠的门,门用木板或铁板制成,长50cm,宽60cm,用铰链固定在踏脚梯杠对面框边上,铰链对面的踏脚杠和两框边的两个角设门杠,用于关门。把天梯与用梯设施结合端口结合于用梯设施。使用:操作工从地面上梯,每通过一个门,随即把门关好,直到操作室;操作工要下去,每到一个门,随即把门打开,直到地面。

Claims (1)

1.一种防坠落天梯,其特征是:有踏脚梯杠,踏脚梯杠左右和对面设置围护栏,围护栏和踏脚梯杠内设置关门后与上下方向垂直的防坠门。
