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。 因为有这样一个特殊的结,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。
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
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, 它是利用皮带传动装置, 使特殊结下端的绳子过绳式地缠绕在皮带轮之后受压固 定、 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也就越来越小的问题, 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, 还设置一个皮带传动装 说 明 书
置和用于安装皮带传动装置的支座、 连接件, 所述皮带传动装置主要包括轴、 皮带轮、 皮带, 所述皮带传 动装置至少有一个皮带轮设置有用于容纳工作绳的绳槽, 特殊结之后的工作绳过绳式地缠绕在所述绳槽 上并且在皮带的压力下受压固定, 所述绳槽的入口侧和出口侧均设置有固定在支座上的导绳件。
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: 所导绳件是由钢丝线弯曲之后呈开口的环形件。
本发明的优选方案之三: 在皮带传动装置的一个皮带轮上还设置有用于驱动皮带传动装置转动的手柄 组件, 所述手柄组件主要包括: 手柄、 插头、 套筒、 弹性件、 用于固定套筒及弹性件的卡件, 并且在支座 上还设置有用于固定皮带轮并且与手柄插头相配合的插孔, 在皮带轮上还设置有用于安装手柄组件的手柄 安装孔。
本发明的优选方案之三: 所述乘载装置为安全带, 采用此方案时人体取直立悬吊姿势。
本发明的优选方案之四: 所述乘载装置主要由吊带、 衬带和座板构成的座板装置。 采用此方案时人体 取坐式姿势。
本发明的有益效果是, 本发明提出一种悬吊下降系统, 它是利用皮带传动装置, 使特殊结下端的绳子 在绕过皮带轮之后受压固定、 对特殊结产生拉力, 克服了人体离地面越来越近时导致绳子对特殊结的拉紧 力也就越来越小的问题, 可以有效防止发生意外。
