技木领域 Technical field
本发明涉及一种下降器, 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。 The present invention relates to a descender, and more particularly to a descender that is manually controlled by gravity of the human body.
背景技术 Background technique
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、 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 夕卜, 卸扣式下降器由于存在一些安全问题,说目前已不提倡使用。 In the "Technical Specifications for Safety of Seat Type Single Slings for Building Exterior Wall Cleaning", the types of descenders today include: rod type, multi-plate type, 8-word ring type and shackle type. When using the 8-word ring lowering device or the shackle type lowering device, the operator must lift the free end rope up when landing; when the rope length is long, the gravity is very large, and sometimes even the problem of lifting the rope is given. Construction and operation bring a lot of trouble. In addition, due to some safety issues, the shackle-type descender is currently not recommended for use.
棒式虽然很安全, 但在实际使用中, 操作人员在下降时操作也很不方便; 使用时, 操作人员将工作绳 自由端绕在下滑绳口中可以锁定下降器, 将工作绳从下书滑绳口中解开则可实现下降, 但在解开时应注意向 下拉住工作绳以防止突然下降; 这样的操作给使用者带来了很大的不便。 因此, 即使 8字环式下降器在操 作上也存在不方便的问题, 人们还是愿意选择它。 Although the stick type is very safe, in actual use, the operator is also inconvenient to operate when descending; when using, the operator can wind the free end of the working rope around the sliding rope mouth to lock the lowering device, and slide the working rope from the lower book. The unwinding of the rope mouth can achieve a drop, but when unwinding, care should be taken to pull down the working rope to prevent sudden drop; such an operation causes great inconvenience to the user. Therefore, even if the 8-word loop downer is inconvenient in operation, people are still willing to choose it.
发明内容 Summary of the invention
为了解决棒式下降器存在使用不方便的问题, 本发明提出一种棒式下降器, 通过设置由人手控制上、 下滑行的压绳件, 当压绳件向上滑行后对芯轴上的绕绳进行挤压, 绕绳摩擦力增大, 人体停止下降; 当压 绳件向下滑行时绕绳不再被压紧, 绕绳摩擦力降低, 人体下降。 本发明提出的下降器, 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。 In order to solve the problem of inconvenient use of the bar type reducer, the present invention proposes a bar type descender, which is provided with a pressure rope member which is controlled by a human hand to slide up and down, and when the pressure rope member slides upward, the winding on the mandrel When the rope is squeezed, the friction of the rope is increased, and the human body stops falling; when the pressure rope member slides downward, the rope is no longer pressed, the friction of the rope is lowered, and the human body is lowered.

图 1、 图 2、 图 3、 图 4、 图 5、 图 6、 图 7为现有棒式下降器的结构示意图; 其中图 1、 图 2、 图 7为 平面图结构示意图, 图 3、 图 4、 图 5为局部结构示意图, 图 6为外部立体图, 图 2、 图 7为使用时工作绳 的绕绳图。图中显示,现有棒式下降器, 由芯轴 1和外套筒 2组合而成, 所述芯轴 1上设置有上端头 l. la、 下端头 Ub, 芯轴 1两端设置有上吊钩口 1.2a、 下吊钩口 1.2b, 上端头 Ua、 下端头 Ub上分别设置有上 滑绳口 l.lal、 下滑绳口 l. lbl , 在上端头 1.1a上还设置有外套筒 2的定位件 l. la2, 所述外套筒 2上设置 有套口 2.1、 固定口 2.2, 工作绳 3通过固定端 3.1固定在高处、 经芯轴 1上端头 1.1a的上滑绳口 Ual进 入缠绕在芯轴 1上形成绕绳 3.2然后从下端头 1.1b的下滑绳口 l. lbl下垂至低处, 外套筒 2套接在芯轴的 上、下端头上并通过定位件 Ua2与固定口 2.2之间的配合固定, 人体 4固定在芯轴 1的下吊钩口 1.2b上。 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, FIG. 6, and FIG. 7 are schematic structural views of a conventional rod type lowering device; wherein FIG. 1, FIG. 2, and FIG. 7 are schematic structural views, FIG. 3 and FIG. 5 is a partial structural view, FIG. 6 is an external perspective view, and FIG. 2 and FIG. 7 are a roping diagram of the working rope in use. The figure shows that the conventional rod type descender is composed of a combination of a mandrel 1 and an outer sleeve 2, and the mandrel 1 is provided with an upper end l. la and a lower end Ub, and the ends of the mandrel 1 are provided with a hanging The upper end head Ua and the lower end head Ub are respectively provided with an upper sliding rope opening l.lal, a sliding rope opening l. lbl, and an outer sleeve is also arranged on the upper end head 1.1a. 2, the positioning member l. la2, the outer sleeve 2 is provided with a sleeve 2.1, a fixed port 2.2, the working rope 3 is fixed at a high position through the fixed end 3.1, through the upper sliding shaft of the upper end 1.1a of the mandrel 1 Ual enters the mandrel 1 to form a roping 3.2 and then hangs down from the lower rope end l. lb of the lower end 1.1b to the lower part. The outer sleeve 2 is sleeved on the upper and lower ends of the mandrel and passes through the positioning member Ua2. Fixed with the fixing port 2.2, the human body 4 is fixed on the lower hook opening 1.2b of the mandrel 1.
图 2为现有棒式下降器的一种绕绳图, 图中显示, 绳子通过固定端 3.1固定在高处, 然后直接进入上 滑绳口 l. lal缠绕在芯轴 1上。 图 7为现有棒式下降器的另一种绕绳图, 图中显示, 绳子通过固定端 3.1 固定在高处, 然后穿过上吊钩口 1.2a、 进入上滑绳口 l. lal再缠绕在芯轴 1上。 图 2的缠绳方法很方便, 由于工作绳不穿过上吊钩口 1.2a而是直接进入上滑绳口 l. lal , 因此下降器可以在工作绳的任何位置上缠 绕工作绳, 给抢险救生或高空作业带来方便。 图 7的缠绕方法给绕绳造成一定的麻烦, 因为绳子的另一个 端头必须从上吊钩口 1.2a中穿过。 Fig. 2 is a roping diagram of a conventional rod type lowering device, the figure shows that the rope is fixed at a high position through the fixed end 3.1, and then directly enters the upper sliding rope opening. l. lal is wound on the mandrel 1. Figure 7 is another roping diagram of the conventional rod type lowering device, the figure shows that the rope is fixed at a high place through the fixed end 3.1, and then passes through the upper hook opening 1.2a, enters the upper sliding rope opening l. lal and then entangles On the mandrel 1. The winding method of Figure 2 is very convenient. Since the working rope does not pass through the upper hook opening 1.2a but directly enters the upper sliding rope opening l. lal, the lowering device can wrap the working rope at any position of the working rope for the rescue lifesaving Or work at heights for convenience. The winding method of Figure 7 causes some trouble for the roping because the other end of the rope must pass through the upper hook opening 1.2a.
图中显示, 在现有技术中, 棒式下降器的芯轴 1与上端头 l. la、 下端头 1.1b是一体式地浇铸或焊接固 定在一起的。 其工作原理是利用缠绕在下降器芯轴 1上的绕绳 3.2所产生的摩擦力来控制下降器的下降速 度, 可根据人体 4重量的大小来选择绕绳 3.2的圈数, 在芯轴 1上缠绕工作绳之后再套上外套筒 2, 即可 悬吊进行消防逃生、 抢险、 建筑物外墙清洗或由上向下运送物件等工作。 使用时, 操作人员将工作绳自由 端 3. 3绕在下滑绳口 l. lbl中可以锁定下降器, 将工作绳 3. 3从下滑绳口 1. Ibl中解开则可实现下降, 但 在解开时应注意向下拉住工作绳以防止突然下降; 这样的操作给使用者带来了很大的不便。 因此, 即使 8
字环式下降器在操作上也存在不方便的问题, 人们还是愿意选择它。 The figure shows that in the prior art, the mandrel 1 of the rod lowering device is integrally cast or welded together with the upper end l. la and the lower end 1.1b.

When in use, the operator can lock the free end of the working rope 3. 3 around the sliding rope mouth l. lbl can lock the lowering device, the working rope 3. 3 can be lowered from the sliding rope opening 1. Ibl can be lowered, but in When unwinding, care should be taken to pull down the working rope to prevent sudden drop; such an operation causes great inconvenience to the user. So even 8 The word loop downer also has inconvenient problems in operation, and people are still willing to choose it.
