实施例1
高层逃生背包100与传统的安全带相比,更加舒适、安全,并且使用的时候简单,直接将高层逃生背包100通过背包本体200背在背上,即可进行逃生。图1为本实施例提供的高层逃生背包100第一结构示意图;图2为本实施例提供的高层逃生背包100第二结构示意图。请一并参阅图1和图2,本实施例中,高层逃生背包100包括背包本体200和高层逃生缓降器300,背包本体200内设置高层逃生缓降器300。背包本体200背在用户身上,背包本体200的设置使用户身上没有勒缚感,使高层逃生背包100的使用更加舒适。
背包本体200包括背包主体220和背包安全带210,背包安全带210连接于背包主体220,背包主体220内设置高层逃生缓降器300。用户将背包安全带210绑缚在用户身上,背包安全带210的设置使用户身上没有勒缚感,使高层逃生背包100的使用更加舒适。
详细地,请参阅图2,背包安全带210包括连接带211,两根肩部绑带212、两根腰部绑带213和两根裆部绑带214,连接带211具有第一端215和第二端216,每根肩部绑带212的一端与背包主体220连接,另一端设置于第一端215,每根腰部绑带213的一端与背包主体220连接,另一端设置于第一端215,每根裆部绑带214的一端与背包主体220连接,另一端设置于第二端216,且肩部绑带212、腰部绑带213和裆部绑带214从上到下依次设置。
即肩部绑带212用于固定用户肩部,裆部绑带214用于固定用户裆部,腰部绑带213用于固定用户的腰部。用户在高层逃生的时候,由于重力作用拉动背包主体220, 背包主体220会朝上运动到用户的上方,会对用户造成束缚感,并且,造成高层逃生背包100不能安全稳定的下降,所以,背包安全带210具有裆部绑带214,裆部绑带214的设置,可以对用户的裆部进行捆绑,避免高层逃生背包100在使用的过程中朝上运动,用户的使用更加舒适,使高层逃生背包100能够安全稳定的下降。
第一端215设置有卡扣217,第二端216设置有绑扣。即为了使背包主体220均匀承受用户的重力,肩部绑带212与腰部绑带213通过卡扣217与第一端215连接,裆部绑带214通过绑扣与第二端216连接。同时,卡扣217和绑扣的设置还可以调节连接带211的长度,不同身高、体重的用户都能够进行使用。
图3为本实施例提供的高层逃生缓降器300的第一剖视图;图4为本实施例提供的高层逃生缓降器300的第二剖视图;图5为本实施例提供的高层逃生缓降器300的结构示意图。请一并参阅图3-图5,本实施例中,高层逃生缓降器300设置在背包主体220内,包括绳索320、绕绳机构340和变速机构360,绳索320设置于绕绳机构340,通过变速机构360的作用,达到制动的作用。
绕绳机构340包括架体350以及转动设置于架体350的绕绳盘,架体350是高层逃生缓降器300的其他部件安装的基础。请参阅图3,架体350包括相对设置的第一安装板351和第二安装板352以及端盖353,绕绳盘转动设置于第一安装板351和第二安装板352之间,即绕绳盘可以相对于第一安装板351和第二安装板352发生转动,端盖353设置于第二安装板352的远离第一安装板351的一侧,即第一安装板351、第二安装板352以及端盖353依次设置。
第一安装板351可以是背板,第二安装板352可以是面板,端盖353设置在面板的远离背板的一侧,即当用户使用高层逃生缓降器300的时候,靠近背部的第一安装板351为背板,远离背部的第二安装板352为面板,端盖353设置在面板的远离背板的一侧,不会对用户造成挤压,用户能够舒适、安全平稳的下降。
第一安装板351和第二安装板352之间设置多根连接杆,连接杆的两端分别与第一安装板351和第二安装板352连接,增加高层逃生缓降器300的强度,方便对其进行安装。
在第一安装板351和第二安装板352之间进行绕绳盘的设置,绳索320绕设于绕绳盘且一端固定于绕绳盘,另一端与固定件310连接。使用高层逃生缓降器300的时候,将固定件310挂在事先安装的挂钩上进行逃生。
请参阅图3和图4,绕绳盘包括第一挡板342、第二挡板343、中空的绕绳环341和转动轴344,第一挡板342、绕绳环341和第二挡板343均设置在第一安装板351和第二安装板352之间,第一挡板342和第二挡板343分别设置于绕绳环341的两侧, 且第一挡板342与第一安装板351接触,第二挡板343与第二安装板352接触,当绳索320缠绕在绕绳环341上的时候,第一挡板342和第二挡板343阻隔绳索320与第一安装板351和第二安装板352接触,避免绳索320与第一安装板351和第二安装板352之间产生摩擦力。
本实施例中,转动轴344穿过第一挡板342和第二挡板343转动设置于第一安装板351和第二安装板352,且转动轴344设置于绕绳盘内,用户从高层跳下的时候,绳索320不断拉伸出来,使饶设绳索320的绕绳盘不断转动,绕绳盘内的转动轴344发生转动。
第一安装板351和第二安装板352均设置有轴槽,轴槽内设置轴套,两个轴套与转动轴344同轴设置,转动轴344设置在两个轴套内。方便转动轴344的设置,使转动轴344更加容易转动。
变速机构360设置于端盖353内,使整个高层逃生缓降器300的结构更加紧凑、合理,且不会影响高层逃生缓降器300的外观,使高层逃生缓降器300能够安全稳定的下降。
图6为本实施例提供的变速机构360的结构示意图;图7为本实施例提供的端盖353的结构示意图。请参阅图6和图7,本实施例中,变速机构360包括与绕绳盘同步运动的主动轮361和至少一个减速机构370,即主动轮361设置于转动轴344的远离绕绳环341的一端,绕绳环341转动的时候,与绕绳环341连接的第一挡板342和第二挡板343发生转动,则与第一挡板342和第二挡板343连接的转动轴344发生转动,从而使传动轴上的主动轮361转动。
每个减速机构370均包括与主动轮361啮合的从动轮371、设置于从动轮371的连接轴372、摩擦轮373和用于与架体350产生摩擦力的摩擦部374,主动轮361的直径大于从动轮371的直径,摩擦轮373套设于连接轴372的远离从动轮371的一侧,摩擦部374位于摩擦轮373与架体350之间,即摩擦部374位于摩擦轮373与端盖353之间,即从内到外依次设置连接轴372、摩擦轮373、摩擦部374和端盖353。
将固定件310挂在事先安装的挂钩上,用户从高层跳下的时候,绳索320不断拉伸出来,使饶设绳索320的绕绳盘不断转动,从而带动与绕绳盘同步运动的主动轮361转动,由于主动轮361的直径大于从动轮371的直径,与主动轮361啮合的从动轮371就会更加快速的转动,从而使连接轴372快速转动,套设在连接轴372上的摩擦轮373也快速转动,由于离心力的作用,摩擦部374高速转动时,摩擦部374会朝向远离摩擦轮373的径向方向即朝向远离摩擦轮373的方向运动,从而使摩擦部374与端盖353接触,使摩擦部374与端盖353之间产生摩擦力,从而达到减缓下降速度的目的。通 过摩擦部374与端盖353之间的摩擦,用户能够安全稳定地下降,达到高层逃生的目的。
优选地,主动轮361的直径是从动轮371直径的5-8倍,在能够有效安装的基础上,尽可能成倍提高从动轮371的转动速度,以便能够达到制动,使用户能够安全稳定的降落。
请参阅图4和图5,本实施例中,端盖353包括盖板354以及围设在盖板354外周的侧壁板355,侧壁板355的远离盖板354的一侧设置于第二安装板352,摩擦部374沿摩擦轮373的径向方向运动的时候与侧壁板355的内壁摩擦,使摩擦部374与侧壁板355之间产生摩擦力,从而对高层逃生缓降器300进行制动。
本实施例中,侧壁板355上与摩擦部374接触的内壁设置有多条圆环形的槽壁381,即侧壁板355上与摩擦部374接触的内壁不光滑,可以增大摩擦部374与侧壁板355之间的摩擦力;同时,如果不设置圆环形的槽壁381,则摩擦部374长时间与侧壁板355摩擦的时候,则会使摩擦部374表面上由于摩擦而产生的粉末粘在侧壁板355的内壁,使其打滑,所以,在侧壁板355的内壁设置圆环形的槽壁381,由于摩擦而产生的粉末掉入圆环形的槽壁381,不会影响摩擦部374与侧壁板355内壁之间的摩擦,达到匀速下降的目的。
优选地,减速机构370设置有两个,两个减速机构370分别设置于主动轮361的两侧。即从动轮371、摩擦轮373和摩擦部374均设置两个,每个减速机构370的从动轮371、摩擦轮373以及摩擦部374的连接方式相同,两个从动轮371的轴线通过主动轮361的轴线对称设置,进一步提高高层逃生缓降器300的使用安全性,用户在使用高层逃生缓降器300的时候,能够更加安全稳定的下降,避免用户在使用的时候造成恐慌。
与减速机构370配合的是:侧壁板355为两个环形的侧板,一个减速机构370的摩擦部374沿相应的摩擦轮373的径向方向运动的时候与一个侧板的内壁摩擦。则在制动的时候,两个减速机构370的摩擦部374都能够与侧板进行摩擦,进一步提高高层逃生缓降器300制动的效果,进一步提高高层逃生缓降器300的使用安全性,达到更加平稳的下降的效果。
优选地,每个减速机构370的摩擦部374设置有两个,两个摩擦部374间隔设置并通过弹簧378连接。在摩擦轮373高速转动的时候,两个摩擦部374都朝向远离摩擦轮373的方向运动,如果摩擦轮373的转动速度过快,则摩擦部374的离心力则会过大,那么摩擦部374就会与侧壁板355紧密接触,从而容易发生抱死现象,而不能使摩擦部374与侧壁板355之间产生摩擦力,所以,在两个摩擦部374之间设置弹簧 378,即两个摩擦部374之间设置两个弹簧378,每个弹簧378的两端分别连接一个摩擦部374,当摩擦部374与侧壁板355之间的接触过于紧密的时候,由于弹簧378的作用,会对摩擦部374产生拉力,将摩擦部374往回拉,保持摩擦部374与侧壁板355之间位于合适的位置,使其能够相互摩擦,达到制动的目的。
优选地,摩擦轮373的外轮面设置有两个安装槽377,一个摩擦块375分别设置于一个安装槽377内,通过安装槽377的设置,可以限制摩擦部374朝向主动轮361或盖板354的方向运动,使摩擦部374由于离心力的作用下,只能朝向远离摩擦轮373的径向方向运动,与端盖353的侧壁板355的摩擦力更大,缓降效果更好,从而达到安全稳定的下降的目的。
更佳地,摩擦部374包括摩擦块375和摩擦片376,摩擦块375设置于安装槽377内并位于摩擦轮373外,摩擦片376设置于摩擦块375外并位于侧壁板355内。摩擦块375是金属摩擦块,摩擦片376为石棉摩擦片。金属摩擦块的重力较大,在摩擦轮373高速转动的情况下,摩擦块375的离心力更大,摩擦块375朝向远离摩擦轮373的方向运动的效果更好;而石棉摩擦片的设置,可以增大摩擦片376与侧壁板355之间的摩擦力,进一步提高高层逃生缓降器300的下降平稳性,同时,石棉摩擦片有很好的耐高温效果,能够承受由于摩擦力产生的高温,增加摩擦片376的使用寿命。
优选地,在每个摩擦部374的摩擦块375的两端均设置固定环379,弹簧378的两端分别安装在两个摩擦块375的固定环379内,对弹簧378进行安装,也使两个摩擦块375之间的弹力分布更加均匀。本实施例中,摩擦片376和摩擦块375之间通过螺钉连接,也可以通过粘接的方式进行连接,能够将其结合在一起,并且方便拆卸和更换。
图8为本实施例提供的绳索限位装置400的第一结构示意图;图9为本实施例提供的绳索限位装置400的第二结构示意图。请一并参阅图8和图9,本实施例中,绕绳机构340还包括绳索限位装置400,绳索限位装置400的两端均固定于第一安装板351和第二安装板352,绳索限位装置400上设置有限位孔410,绳索320穿过限位孔410与固定件310连接。通过绳索限位装置400的设置来改变绳索320的方向,保证绳索320位于高层逃生缓降器300的中心。
优选地,绳索限位装置400包括滑动辊组件420和绳索挡板430,滑动辊组件420和绳索挡板430的两端均固定于第一安装板351和第二安装板352,绳索挡板430位于滑动辊组件420的上方,绳索挡板430上设置有限位孔410,绳索320依次穿过滑动辊和限位孔410与固定件310连接。通过滑动辊组件420和绳索挡板430的设置来改变绳索320的方向,保证绳索320处于高层逃生缓降器300的中心,同时,滑动辊组件 420的设置,可以减小绳索320与绳索挡板430的摩擦力,避免绳索320磨损,延长高层逃生缓降器300的使用寿命。
更佳地,滑动辊组件420包括两个第一滑动辊421和两个第二滑动辊422,第一滑动辊421设置相对于第二滑动辊422更加靠近行星减速机构370,即在使用高层逃生背包100的时候,第二滑动辊422、第一滑动辊421和行星减速机构370从上到下依次设置,两个第二滑动辊422的两端均设置于绳索挡板430,两个第一滑动辊421的两端分别设置于第一安装板351和第二安装板352,两个第一滑动辊421的轴线与两个第二滑动辊422的轴线相交,绳索320的一端安装在绕绳盘上,另一端先穿过两个第一滑动辊421的中间,再穿过两个第二滑动辊422的中间,从限位孔410穿出,穿过背包主体220与固定件310连接。
通过两个第一滑动辊421和两个第二滑动辊422的设置,优选两个第一滑动辊421的轴线与两个第二滑动辊422的轴线垂直,可以使绳索320在两个第一滑动辊421和两个第二滑动辊422之间穿梭,对绳索320的运动方向具有一定的限制作用,在使用单减速高楼逃生背包的时候,避免绳索320卡死,滑动顺畅,避免绳索320大幅度摆动,减小绳索320受到的摩擦力,增加绳索320的使用寿命,提高高层逃生背包100的使用安全性。
优选地,两个第一滑动辊421中,其分别为一大一小,绳索320从较大的第一滑动辊421上绕设,穿过两个第二滑动辊422之间,进一步避免绳索320的晃动,提高高层逃生背包100的使用安全性与舒适性。
本实施例中,绳索320为钢丝绳,其不会被烧坏,而且强度高,使用寿命长。或其他能够进行高层缓降的绳索320也属于本申请保护的范围。
