图 1、 图 2、 图 3为现有 8字环式悬吊器的结构示意图; 其中图 1为立体结构示意图、 图 2平面结构 示意图, 图 3为使用时的结构示意图。
图 1、 图 2中显示, 现有 8字环式悬吊器由具有穿绳孔 1. 1、 吊孔 1. 2的吊体 1构成。
图 3为使用时的结构示意图,图 3中显示,使用时,工作绳从穿绳孔 1. 1中穿过并套接在吊体腰部 1. 3 上, 工作绳固定端 3. 1经穿绳孔 1. 1固定在高处, 工作绳自由端 3. 2经穿绳孔 1. 1下垂至低处, 人体 5通 过连接件 4与吊孔 1. 2连接固定。 使用时, 由于现有 8字环式悬吊器自锁有困难, 因此使用者在下降过程 中, 必须对工作绳自由端 3. 2施加持续的拉力才能控制下降速度, 如果需要长时间悬停, 必须将工作绳自 由端进行固定处理, 因此, 由于操作上的不方便, 对于没有受过专业训练的人员来讲, 使用时存在一定的 安全隐患。
图 4、 图 5、 图 6、 图 7、 图 8、 图 9为变截面绕绳轮第一个实施例的结构示意图; 其中图 4为主视图, 图 5为左视图, 图 6为 I-I位置的剖视图 (槽底剖面图), 图 9为立体图; 图 7、 图 8为绳索缠绕在绕绳轮 上的结构示意图, 其中图 8为图 7在绕绳轮转过一个角度后的结构示意图。

在本实施例中, 沿一个圆周方向只出现一个最深处凹槽 6. 1AA、 一个最浅处凹槽 6. 1AB。 本发明提示, 在其它实施例中, 沿一个圆周方向可以出现多个最深处凹槽和多个最浅处凹槽。
在本实施例中, 轮体为圆形结构, 本发明提示, 在其它实施例中, 也可以将轮体改进为椭圆形结构, 前提是确保轮体的转动不受影响。
图 10、 图 11、 图 12、 图 13为变截面绕绳轮第二个实施例的结构示意图; 其中图 10为主视图、 图 11 为左视图, 图 12为 K-K位置的剖视图 (槽底剖面图), 图 13为立体图。 图中显示, 与第一个实施例不同 的是, 在本实施例中, 最浅处凹槽 6. 1AB深度为 0, 夹角为 180度, 也就是说, 绕绳轮在此处呈光滑圆柱 面结构 (不存在凹槽)。 在本实施例中, 变截面绕绳轮沿一个圆周方向只在一个点处呈光滑圆柱面 (不存 在凹槽); 本发明提示, 在其它实施例中, 变截面绕绳轮沿一个圆周方向可以在一定的角度范围内呈光滑 圆柱面 (不存在凹槽)。

图 17为变截面绕绳轮第六个实施例的结构示意图。 图中显示, 与第一个实施例不同的是, 在本实施 例中, 所述绳索凹槽的两个侧面设置有护绳板 6. 4A、 6. 4B, 护绳板 6. 4A、 6. 4B的作用是将绳索限制在绳 索凹槽中。
图 18为变截面绕绳轮第七个实施例的结构示意图。 图中显示, 与第一个实施例不同的是, 在本实施 例中, 所述轮体 6. 1由左轮片 6-1、 右轮片 6-2贴合固定而成的给合式结构, 左轮片 6-1、 右轮片 6-2贴 合固定之后构成变截面绳索凹槽, 在本实施例中, 所构成的绳索凹槽为 V形凹槽 6. 1A。
图 19、 图 20、 图 21、 图 22为变截面绕绳轮第八个实施例的结构示意图, 其中图 19为主视图、 图 20 为左视图, 图 21为 L-L位置的剖视图 (槽底剖面图), 图 22为立体图。 图中显示, 与第一个实施例不同 的是, 在本实施例中, 轮体 6. 1呈椭圆形结构; 在图 21 的剖视图中显示, 绳索凹槽的槽底剖面呈圆形结 构, 绳索凹槽 6. 1A的截面沿圆周方向变化, 绳索凹槽 6. 1A在一个圆周里出现两个最深处凹槽 6. 1AA、 两 个最浅处凹槽 6. 1AB。
图 23、 图 24、 图 25、 图 26为变截面绕绳轮第九个实施例的结构示意图, 其中图 23为主视图、 图 24 为左视图, 图 25为 M-M位置的剖视图 (槽底剖面图), 图 26为立体图。 图中显示, 与第一个实施例不同 的是, 在本实施例中, 轮体 6. 1呈圆形结构; 在图 25的剖视图中显示, 绳索凹槽的槽底剖面呈椭圆形结 构, 绳索凹槽 6. 1A的截面沿圆周方向变化, 绳索凹槽 6. 1A在一个圆周里出现两个最深处凹槽 6. 1AA、 两 个最浅处凹槽 6. 1AB。
本发明提示, 在其它实施例中, 所述绳索凹槽的截面可以呈其它弧形结构并且凹槽的深度和 /或宽度沿 圆周方向发生变化。
图 27、 图 28、 图 29、 图 30、 图 31、 图 32、 图 33、 图 34为采用变截面绕绳轮的悬吊器一个实施例的 结构示意图。 其中图 27、 图 28、 图 29、 图 30为局部零件图; 图 31、 图 32为整体结构示意图; 图 33、 图 34为使用时的结构示意图, 其中 33为悬停时的结构示意图, 图 34为下降时的结构示意图。 在图 31、 图 32中显示, 在本实施例中, 悬吊器由具有吊孔 1. 2的吊体 1以及设置在吊体上的 U形穿 绳件 2构成, U形穿绳件 2为圆形钢材弯曲而成, 吊体上设置有固定插孔 1. 5. 1、 1. 5. 2, U形穿绳件的两 个插脚 2. 1、 2. 2分别插入固定插孔 1. 5. 1、 1. 5. 2当中并焊接固定在吊体 1上, U形穿绳件 2的 U形口与 吊体之间构成穿绳孔 1. 1 ; 吊孔 1. 2设置在偏向一侧的位置, 在吊体 1的另一侧还设置有控制悬吊器偏转 的操控手柄 1. 4。 在图 29、 图 30中显示, 在吊体 1上设置一根固定轴 7并在轴上设置单向轴承 8, 变截面 绕绳轮轮体 6. 1的安装孔 6. 2与单向轴承 8配合将变截面绕绳轮轮体 6. 1安装在固定轴 7上, 变截面绕绳 轮轮体 6. 1可以绕轴做单向转动。
在图 27、 图 28中显示, 在本实施例中, 变截面绕绳轮轮体 6. 1还设置有操控件 6. 3, 人手通过操作 操控件 6. 3可以使变截面绕绳轮轮体 6. 1做单方向转动。
图 33、 图 34为使用时的结构示意图, 33为悬停时的结构示意图, 图 34为下降时的结构示意图。 图 33显示, 使用时, 工作绳 3从穿绳孔穿过并绕过变截面绕绳轮轮体 6. 1缠绕在绳索凹槽上, 工作绳固定端 3. 1经穿绳孔 1. 1固定在高处, 工作绳自由端 3. 2经穿绳孔 1. 1下垂至低处, 人体 5通过连接件 4与吊孔 1. 2连接固定; 当人体 5单独由吊孔 1. 2承吊时, 穿绳孔中的工作绳固定端 3. 1与工作绳自由端 3. 2两者 之间互相接触并压紧, 阻止工作绳滑行, 使人体 5处于悬停状态。
图 34显示, 当需要下降时, 人体通过操控手柄 1. 4对悬吊器施加拉力时悬吊器将发生偏转, 使穿绳 孔 1. 1中的工作绳固定端 3. 1与工作绳自由端 3. 2两者之间的压力减小、 或使两者分离, 绳子开始滑行、 人体下降。 由于单向轴承 8只能做单向转动, 在下降过程中, 变截面绕绳轮轮体 6. 1即使在绳索摩擦力的 作用下也不能转动。但当人手通过操作操控件 6. 3时可以使变截面绕绳轮轮体 6. 1沿绳索运行的相反方向 转动, 绕绳轮转动时, 由于与绳索接触的凹槽深度和角度发生改变, 使绳索与绕绳轮之间的摩擦力也发生 变化, 由此调节人体下降速度。
