Description

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, 并经过身体检査和安全技术培训, 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。
为了规范用语, 本文中各类零部件的名称引用 《建筑物外墙清洗作业座板式单人吊具安全技术规范》 的有关资料。 悬吊下降系统主要由工作绳、 下降器、 连接器、 座板装置组成。 下降器: 安装在工作绳上, 以作业人员自身重量为动力、 通过手工控制的装置; 现今下降器的种类包括: 棒式、 多板式、 八字环式和 卸扣式, 其中卸扣式下降器俗称 U型蟹扣。 连接器: 可将系统内部零件连接在一起, 具有常闭活门的环类 零件。 座板装置: 乘载作业人员的装置, 由吊带、 衬带和座板组成。
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, 操作人必须将特殊结下端绳子往上提, 使所述特殊的结不被 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
为了克服现今座板式单人用吊具当离地面越近时, 特殊结可能发生打滑而导致意外的问题, 本发明 提出一种悬吊下降系统, 它增设手动葫芦并通过手动葫芦控制一个绕绳轮, 所述绕绳轮上设置有容纳绳子 的绳槽,将特殊结之后的绳子过绳式地缠绕在绕绳轮上,绕绳轮上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, 绳子被提升, 人体下降, 绳 子被提升多少, 人体下降多少; 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, 确保了特殊结之后的绳子对特殊结产生拉力, 克服了人体离地面越来越近导致绳子对特殊结的拉 紧力越来越小的问题, 可确保下降过程不会发生失控; 可以有效的防止发生意外。
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, 主要包括工作绳、 下降 器、 连接器、 乘载装置, 所述工作绳在下降器上打上一个特殊的结, 其特征是, 还设置手动葫芦、 绕绳 轮、用于安装固定的固定装置,所述手动葫芦控制所述绕绳轮转动,所述绕绳轮上设置有容纳绳子的绳槽, 特殊结之后的工作绳过绳式地缠绕在所述绕绳轮的绳槽上; 所述固定装置主要包括连接件、 支座、 绕绳轮 轮轴、 安装绕绳轮轮轴的轴座, 所述轴座固定在支座上, 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; 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。
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; 手动葫芦驱动的不是起重链轮而是绕绳轮轮轴。
本发明的优选方案之一: 所述连接件将支座固定在下降器上, 所述乘载装置通过连接器将人体固定在 所述支座上。
本发明的优选方案之二: 所述绕绳轮上的绳槽优选 V形结构。
