Description

多板式下降器 技术领域
本实用新型涉及一种下降器， 尤其涉及一种以人体自身重量为重力、 通过手工控制的下降器。
背景技术
在《建筑物外墙清洗作业座板式单人吊具安全技术规范》 中， 现今下降器的种类包括： 棒式、 排线式 (多板式） 、 8字环式和卸扣式。 采用 8字环式下降器或卸扣式下降器时， 操作人员在降落时必须将自由 端的绳子往上提起； 当绳子长度很长时重力很大， 有时甚至出现提不动绳子的问题， 给施工和操作带来 很大的麻烦。 另外， 卸扣式下降器由于存在一些安全问题， 目前已不提倡使用。
排线式 （多板式） 下降器应用比较广泛， 但存在控制结构复杂、 加工制造成本高等诸多缺点。
实用新型内容
为了解决现今排线式 （多板式） 下降器存在控制结构比较复杂、 加工制造成本高的缺点， 本实用新型 提出一种排线式下降器， 通过设置软性控制绳， 当悬吊时， 工作绳受力， 排杆向上收拢， 工作绳摩擦力增 大， 人体停止下降； 当用手向下牵拉软性控制绳时， 排杆向下释放展开， 工作绳摩擦力降低， 人体下降。 而且， 为了解决排杆的开口滑孔可能对工作绳产生损伤， 还设置有绕绳定位挡杆， 通过定位档杆对工作绳 的缠绕位置进行限制。 本实用新型提出的下降器， 不但可以作为建筑物外墙清洁、 装修等施工时的悬吊工 具， 还可以作为建筑物消防救生、 抢险或高空救生、 作业时悬吊工具， 还可作为人员空降时的专用设备。
本实用新型解决技术问题采用的技术方案是， 一种下降器， 由本体和若干排杆构成， 所述本体具有 两条竖杆， 所述排杆一端设置有闭口滑孔， 排杆通过闭口滑孔安装在本体的竖杆上， 排杆的另一端设置 有另一个滑孔且至少在每隔一根排杆时滑孔为开口滑孔， 所述开口滑孔作为绕绳活门， 工作绳一端固定 在高处、 经过排杆的绕绳活门绕压在排杆上、 另一端自由悬垂至低处， 人体与本体连接固定， 设置有软 性控制绳， 所述控制绳上对应于各个排杆的上侧位置设置有对应的结点， 用手向下牵拉控制绳时， 所述 对应结点带动对应排杆向下展开， 其特征是， 还设置有绕绳定位挡杆， 绕绳定位档杆设置在排杆上并且工 作绳从定位档杆中绕过。
进行悬吊时， 首先将工作绳通过固定端固定在高处、 经过排杆的开口滑孔绕压在排杆上、 然后由自 由端自由悬垂至低处， 在弹性件的作用下， 排杆向上收拢； 然后将人体与本体连接固定； 由于排杆呈向 上收拢状态， 排杆之间的距离缩小， 工作绳摩擦力增大， 人体停止下降； 当用手向下牵拉控制绳时， 排 杆逐渐向下展开， 排杆之间的距离扩大， 工作绳摩擦力降低， 人体下降； 由此， 通过操作控制绳， 人体 可以实现下降或悬停。
本实用新型的优选方案为： 最下端的绕绳排杆是下降器最下端的排杆， 在最下端的绕绳排杆上设置 有朝向下侧的绕绳定位档杆。
本实用新型的优选方案为： 最下端的绕绳排杆不是下降器最下端的排杆， 在最下端的绕绳排杆上设置 有绕绳定位档杆， 并且在最下端的绕绳排杆的相邻排杆上设置有容纳定位档杆的插孔。
本实用新型的优选方案为： 最上端的绕绳排杆上设置有绕绳定位档杆， 与最上端的绕绳排杆相邻的 排杆设置有容纳定位档杆的插孔。
本实用新型的优选方案为： 在所述竖杆上还设置有支撑杆， 所述支撑杆设置在排杆的最下端， 人体 与支撑杆连接固定。
本实用新型的有益效果是， 使用者只需用手操控控制绳就可以实现下降或悬停， 通过设置工作绳定 位档杆， 使工作绳在滑行过程中位置得到限制， 避免排杆的开口滑孔可能对工作绳产生的损伤， 设备制 造成本低， 使用时操作简单， 安全实用。
