说 明 书 一种悬吊下降系统
技术领域
本发明涉及一种悬吊下降系统, 尤其涉及一种以体自身重量为重力、 通过手工控制的悬吊下降系统。 背景技术
在日常中, 清洁外墙用座板式单人用吊具, 先在楼顶处选一个拴绳子的固定地方,将所有绳子搭角、 搭棱、 搭檐的地方用橡胶垫底,以防磨擦磨损吊绳; 再将吊绳在座式吊板上的下降器里打好一个特殊的结。 因为有这样一特殊的结,所以在工作中,吊板不会往下滑,人控制绳索,可以自由操作, 简单的说 , 当往上 一提绳子、 吊板就往下滑一点,提多少滑多少,提多快滑多快,一直到工作结束。 高空外墙粉刷工程也可以 使用这种工具。 由于使用吊具时, 使用人员除了操作绳索进行下降之外, 还要同地进行施工操作, 由于是 高空作业, 因此工作有一定的危险性。 使用座板式单个吊具高空操作者必须是年满 18周岁的男性公民, 并经过身体检查和安全技术培训, 经考试合格方可作业, 工人上崗前不得饮酒, 有感冒等身体不适症状就 暂停高空作业。 座板式单人用吊具的优点是结构简单, 操作方便, 如果安全措施做得周到, 使用起来安全 性很高。
由于座板式单人用吊具是在下降器里打好一个特殊的结, 并利用下端绳子自身的重量将结拉紧, 将座 板和人体固定并吊在空中, 当需要下降时, 操作人中必须将下端绳子往上提, 使所述的特殊的结不被拉紧, 此时, 人体下降, 绳子提多少, 人体下滑多少,绳子提多快, 人体下滑多快。 随着人体的不断下降, 当人 体离地面越近时, 所述特殊结以下的绳子的重量越来越小, 因此对特殊结的拉紧力也就越来越小, 此时无 需向上提绳子, 人体就可能快速下降, 容易发生意外。
发明内容
现今座板式单人用吊具当离地面越近时, 特殊结以下的绳子的重量越来越小, 对特殊结的拉紧力也 就越来越小, 容易发生意外, 为了克服这个问题, 本发明提出一种悬吊下降系统, 它是利用手动葫芦驱动 一个绕绳轮, 绕绳轮上缠绕绳子, 绕绳轮上设置有容纳绳子的绳槽使绳子与绕绳轮之间具有摩擦力, 防止 绳子在轮上打滑; 当手工控制手动葫芦, 手动葫芦转动时, 绕绳轮转动, 人体下降; 当手动葫芦停止转动 时, 绕绳轮也停止转动, 人体停止下降; 通过手工操作, 人体可逐渐下降; 由于手动葫芦带有反向逆止刹 车功能, 即使在人体重力的作用下, 绕绳轮也不能主动转动, 因此, 可确保下降过程不会发生失控。
本发明解决技术问题采用的技术方案是, 本发明提出的一种悬吊下降系统, 主要包括绳子、 绕绳轮和 固定装置, 所述绕绳轮具有容纳绳子的绳槽, 绳子过绳式地缠绕在所述绳槽上, 所述固定装置主要包括支 座、 绕绳轮轮轴、 安装绕绳轮轮轴的轴座, 轴座固定在支座上, 绕绳轮安装在绕绳轮轮轴上, 绕绳轮轮轴 转动时带动绕绳轮转动, 其特征是,还设置手动葫芦,所述手动葫芦的花键孔齿轮与绕绳轮轮轴安装连接, 花键孔齿轮转动时带动绕绳轮轮轴与绕绳轮一起转动。 通过曳动手动葫芦的手链条驱动花键孔齿轮转动, 说 明 书 由于手动葫芦的花键孔齿轮与绕绳轮轮轴安装连接在一起, 因此, 花键孔齿轮转动时带动绕绳轮轮轴和绕 绳轮一起转动。 由于手动葫芦带有反向逆止刹车功能, 即使在人体重力的作用下,绕绳轮也不能主动转动, 由此确保下降过程不会发生失控, 可有效防止发生意外。
本发明提示, 所述绕绳轮上的绳槽优选 V形结构。
本发明提示, 绕绳轮安装在绕绳轮轮轴上, 是为了实现绕绳轮轮轴带动绕绳轮转动的目的, 其连接方 式可以采用螺栓连接或键连接, 也可以采用其它公知的连接方式, 只要其连接能够使绕绳轮轮轴带动绕绳 轮转动就可以满足要求。
本发明提示, 花键孔齿轮与绕绳轮轮轴之间的机械连接是为了实现花键孔齿轮带动绕绳轮轮轴的目 的, 其连接方式可以采用螺栓连接或键连接, 也可以采用其它公知的连接方式, 只要其连接能够使花键孔 齿轮带动绕绳轮轮轴就可以满足要求。
本发明提示, 在现有的手动葫芦中, 起重链轮是安装在花键孔齿轮上, 因此, 当手链条带动手链轮转 动时, 将摩擦片棘轮、 制动器座压成一体共同旋转, 齿长轴带动片齿轮、 齿短轴和花键孔齿轮一起转动, 最终使花键孔齿轮带动起重链轮一起转动, 最后通过起重链将重物得升; 在本发明中, 手动葫芦没有设置 起重链轮和起重链; 手动萌芦驱动的不是起重链轮而是绕绳轮轮轴。
本发明的优选方案: 在绕绳轮的入口和出口处还设置有导绳装置, 导绳装置主要包括固定板和固定在 固定板上 u形钢丝线。
本发明的有益效果是, 本发明提出一种悬吊下降系统, 通过设置手动葫芦驱动绕绳轮转动, 降落者可 通过手工操作使自身逐渐下降, 由于手动葫芦带有反向逆止刹车功能, 即使在人体重力的作用下, 绕绳轮 也不能主动转动, 由此确保下降过程不会发生失控, 可有效防止发生意外。
