Description
一种建筑机械的爬升装置和布料杆 本申请要求于 2011 年 4 月 19 日提交中国专利局、 申请号为 201110098573.9、发明名称为"一种建筑机械的爬升装置和布料杆"的中国专 利申请的优先权, 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及一种建筑机械的爬升技术, 特别是涉及一种建筑机械的爬 升装置, 还涉及一种包括该爬升装置的布料杆。
背景技术
布料杆是应用广泛的建筑机械之一。 布料杆一般包括底架和杆臂, 杆 臂下端通过适当的回转机构与底架相连。 杆臂由多个节臂通过横向轴顺序 变杆臂末端的位置, 以将混凝土输送到预定的浇注位置。
随着多层或高层建筑物施工技术的发展, 可爬升的布料杆在建筑工程 中得到广泛应用。在普通布料杆基础上,可爬升的布料杆还包括爬升装置, 爬升装置包括一个具有预定长度的立柱,布料杆的底架与立柱的上端固定。 借助于预定楼层, 爬升装置可以使底架及杆臂(为了描述的方便, 下称布 料杆本体)相对于建筑物向上移动, 从而实现布料杆的爬升。
中国专利文献 CN10153428A公开了一种布料杆爬升装置。 该爬升装 置包括导轨、 上导向座、 下导向座、 顶升油缸和支撑机构和立柱。 导轨设 置相应的槽, 并与立柱固定。 上导向座、 下导向座分别与顶升油缸的上端 和下端相连; 支撑机构与位于顶升油缸下端的下导向座相连; 上导向座、 下导向座、 顶升油缸和支撑机构形成爬升装置的驱动机构。 上导向座和下 导向座均具有棘爪式的锁止件, 该锁止件可以卡入导轨的槽中; 在上导向 座或下导向座向上移动时, 该锁止件可以将相应的导向座与导轨锁止, 使 上导向座或下导向座与导轨保持相对固定; 在上导向座或下导向座向下移 动时, 该锁止件可以解除相应导向座与导轨锁止关系, 使上导向座或下导 向座与导轨保持相互独立, 导向座可以相对于导轨向下移动。 在布料杆爬
升时, 下导向座通过支撑机构支撑在建筑物的低楼层的上表面上, 上导向 座的锁止件卡入导轨的槽中; 顶升油缸伸出, 驱动上导向座、 导轨和立柱 同时上升; 当顶升油缸伸长到预定长度后, 下导向座的锁止件卡入导轨的 槽中, 使立柱和导轨不会相对于建筑物向下移动; 顶升油缸缩回, 上导向 座随顶升油缸向下移动, 移动到预定位置, 上导向座的锁止件卡入导轨的 下方的槽中, 再使顶升油缸伸出, 驱动立柱向上移动; 反复进行上述过程, 可以使布料杆本体逐步向上爬升预定的高度, 到达上一层楼层, 以在上一 层楼层进行混凝土施工作业。 在布料杆本体完成一定高度爬升后, 需要将 爬升装置的驱动机构移动到上楼层时, 可以将上导向座和下导向座上的解 锁把手拉到解锁状态, 使上导向座和下导向座的锁止件无法卡入导轨的槽 中, 再通过定滑轮和钢链将爬升机构的驱动机构提升到上一楼层。
上述爬升装置虽然可以实现布料杆本体爬升的目的, 但在需要提升爬 升装置, 将爬升装置的驱动机构向上一楼层转移时, 需要对爬升装置的驱 动机构单独进行操作。 由于布料杆的操作位置一般具有很高的高度, 向上 移动该驱动机构时, 很难通过自动化大型机械实现, 这就需要通过滑轮和 钢链才能实现爬升装置的驱动机构的上移。 因此, 由于需要对爬升装置的 驱动机构进行单独操作, 使得该布料杆爬升过程非常烦瑣, 操作非常不方 便, 爬升效率还很低, 劳动强很大。
上述技术问题不仅存在于布料杆中, 也存在在于具有爬升装置的塔吊 或其他建筑机械中。

请参考图 1 , 该图为本发明实施例一提供的布料杆爬升装置的结构示 意图。 实施例一提供的布料杆爬升装置包括立柱(图中未示出)、 第一框架 100、 第二框架 200和驱动机构。 其中, 第一框架 100高度为一个楼层的高 度 H (图 2a所示)), 第二框架 200高度大于一个楼层的高度 H; 第一框 架 100和第二框架 200在竖向方向上滑动配合。 本例中, 第一框架 100和 第二框架 200均为筒状结构, 第一框架 100套在第二框架 200外侧, 且第 二框架 200与立柱固定; 另外, 第一框架 100和第二框架 200分别设置有 与预定楼层固定的结构。 驱动机构包括相对于第一框架 100中心线径向对 称分布的两个驱动油缸 310, 且驱动油缸 310具有适当长度的缸体和活塞, 以使其伸长状态的长度和收缩状态的长度之差为一个楼层的高度。 当然, 驱动油缸 310不限于为驱动油缸 310, 也可以包括其他动力力的缸类结构 或通过齿轮、 电磁或其他方式实际的驱动部件。
请参考图 2a, 图 2a-2c是实施例一提供的布料杆爬升装置的工作原理 示意图。 实施例一提供的布料杆爬升装置的工作原理如下:
在需要布料杆爬升时, 通过以下步骤实现:
第一步,可以使第二框架 200下端支撑在第一楼层 01的上表面,上端 伸出第二楼层 02的预留口, 可以与第二楼层 02的预留口的支撑托架相配 合; 驱动油缸 310处于收缩状态, 使第一框架 100上端伸入第二楼层 02 的预留口, 如图 2a所示。
第二步, 使驱动油缸 310伸长, 使第一框架 100相对于第二框架 200 向上移动一个楼层的高度;如图 2b所示,使第一框架 100的下端支撑在第 二楼层 02的上表面; 由于第二框架 200高度大于一个楼层的高度 H, 此时 仍然能够保证第一框架 100和第二框架 200之间的滑动配合, 保持第一框 架 100与第二框架 200之间的相互导向作用。
第三步, 如图 2c所示, 再使第一框架 100支撑在第二楼层 02的上表
面, 保持不动, 使驱动油缸 310收缩, 使第二框架 200向上移动一个楼层 的高度。 然后, 可以使第二框架 200下端支撑在第二楼层 02上表面, 上端 伸出第三楼层 03的预留口。
通过上述过程的反复循环, 使布料杆爬升装置在展开状态与缩回状态 之间转换, 可以实现布料杆的逐步爬升。 通过反向移动, 可以实现布料杆 的逐步下降。
利用该布料杆爬升装置能够保证布料杆自动向上爬升, 同时作为驱动 机构的驱动油缸 310本身也随着布料杆的爬升而上升, 因此, 不需要对布 料杆爬升装置的驱动机构进行单独操作, 进而可以筒化布料杆爬升过程, 提高爬升效率, 降低操作人员的劳动强度。
根据上述描述, 可以理解, 第一框架 100不限于套在第二框架 200之 夕卜, 也可以使第一框架 100套在第二框架 200之内; 当然, 第一框架 100 和第二框架 200不限于筒状结构,也可以为其他框架式结构。 实施例一中, 第一框架 100高度等于一个楼层的高度, 第二框架 200高度大于一个楼层 的高度, 这样不仅能够保证第一框架 100和第二框架 200之间的配合, 还 能够保证驱动油缸 310伸长状态下, 缸体与活塞之间的配合的可靠性。 为 了保证第一框架 100和第二框架 200之间滑动配合的可靠性, 保证二者之 间的导向功能,同时保证驱动油缸 310工作的可靠性,可以使第一框架 100 和第二框架 200高度更大, 驱动油缸 310伸长状态的长度和收缩状态的长 度之差也可以更大, 以根据实际需要使第一框架 100或第二框架 200上移 或下移预定的距离。
适当设置第一框架 100和第二框架 200的高度及驱动油缸 310的伸长 状态的长度和收缩状态的长度, 在展开状态下, 使第一框架 100和第二框 架 200形成的框架体的高度大于一个楼层的高度; 此时, 可以使第二框架 200 与立柱固定, 并使布料杆爬升装置以展开状态为起点。 布料杆爬升装 置可以通过下述方式实际爬升: 使第一框架 100相对于建筑物的预定楼层 固定(通过第一框架 100本身的结构), 通过驱动油缸 310的伸缩, 使第二 框架 200相对于第一框架向上移动或向下移动, 使布料杆爬升装置从展开 状态转换到缩回状态;再使第二框架 200相对于建筑物的预定楼层固定(第
二框架 200通过立柱与预定楼层固定); 适当设置驱动油缸 310, 使第二框 架 200位于两个楼层之间的位置; 再通过驱动油缸 310的伸缩, 使第一框 架 100相对于第二框架 200向上或向下移动, 使布料杆爬升装置从缩回状 态转换到展开状态; 由于第一框架 100和第二框架 200形成的框架体的高 度大于一个楼层的高度, 可以使第一框架 100至少能够与一个预定楼层固 定。 这样就能够使第一框架 100和第二框架 200互为基础, 通过驱动油缸 310的伸缩, 反复进行上述过程可以使第一框架 100和第二框架 200逐步 地相对于建筑物的预定楼层向上移动和向下移动, 进而可以使与第一框架 100或第二框架 200固定的立柱上升或下降, 实现布料杆的逐步爬升和下 降。
实施例一中, 驱动机构包括两个位于第一框架 100外的驱动油缸 310, 这样可以保证第一框架 100相对于第二框架 200向上或向下移动时的稳定 性, 进而保证布料杆爬升装置的稳定性。 驱动机构的驱动油缸 310也可以 设置在第二框架 200内。 请参考图 3 , 该图是本发明实施例二提供的布料 杆爬升装置的结构示意图。 实施例提供的布料杆爬升装置中, 驱动机构包 括一个同时位于第一框架 100和第二框架内 200内的驱动油缸 310, 驱动 油缸 310两端分别与第一框架 100和第二框架 200相连。
上述实施例中, 为了保证布料杆的爬升的可靠性, 驱动油缸 310伸长 状态的长度和收缩状态下的长度之差应当不小于一个楼层的高度, 这样对 驱动油缸 310提出的很高的要求, 导致驱动油缸 310的制造成本增加, 还 降低了驱动油缸 310的工作可靠性。
为了减小驱动油缸 310的长度, 本发明实施例三提供了另一种结构的 驱动机构。 请参考图 4和图 5 , 图 4是本发明实施例三提供的布料杆爬升 装置的结构示意图; 图 5是实施例三中, 布料杆爬升装置的驱动机构的立 体结构示意图。
实施例三提供的布料杆爬升装置包括第一框架 100、 第二框架 200和 驱动机构; 第一框架 100和第二框架 200高度均大于一个楼层的高度。 本 例中, 第一框架 100和第二框架 200均为筒状结构, 还设置有相配合的齿 轮与齿条, 齿轮与第一框架 100的内壁可旋转相连; 齿条竖向延伸, 并与
第二框架 200外壁面固定相连, 以保证第一框架 100和第二框架 200相互 的导向作用。
与实施例一中的驱动机构不同, 本实施例中, 驱动机构包括驱动油缸 310、 爬升框架 320和状态转换机构。 驱动油缸 310两端分别与第一框架 100和爬升框架 320相连; 爬升框架 320与第二框架 200在竖向方向上滑 动配合; 状态转换机构位于爬升框架 320与第二框架 200之间; 状态转换 机构能够通过锁止结构改变爬升框架 320与第一框架 100之间的关系, 使 爬升框架 320能够相对于第二框架 200向上移动、 向下移动或与第二框架 200保持固定。 即状态转换机构(状态转换机构的具体实施方式将以后述) 能够通过锁止结构使爬升框架 320和第二框架 200之间形成三种状态。 在 第一种状态下, 使爬升框架 320能够相对于第二框架 200向上移动; 在第 二种状态下, 使爬升框架 320能够相对于第二框架 200向下移动; 在第一 种状态和第二种状态下; 使驱动油缸 310伸缩, 可以改变爬升框架 320与 第二框架 200之间的相对位置; 在第三种状态下时, 使爬升框架 320与第 二框架 200保持固定,进而以第二框架 200为基础,使驱动油缸 310伸缩, 可以使第一框架 100相对于第二框架 200向上或向下移动, 实现布料杆的 爬升或下降。
与实施例一中的驱动机构相比, 实施例三中, 该驱动机构能够将第一 框架 100或第二框架 200移动一个楼层高度(或其他预定的高度) 的过程 分成多个移动距离较小的步骤。 比如: 在需要第一框架 100相对于第二框 架 200向上移动一个楼层高度时,可以通过状态转换机构,使爬升框架 320 和第二框架 200处于第三种状态, 爬升框架 320支撑在第二框架 200上, 使驱动油缸 310伸长, 带动第一框架 100相对于第二框架 200向上移动预 定距离 (比如说, 可以是 0.2个楼层高度); 然后, 再使爬升框架 320和第 二框架 200之间的关系处于第一种状态, 并第一框架 100和第二框架 200 保持不动 (可以通过现有技术, 使第一框架 100和第二框架 200支撑在预 定楼层上 ),使驱动油缸 310收缩,爬升框架 310相对于第二框架 200向上 移动预定的距离; 再使爬升框架 320和第二框架 200之间的关系处于第三 种状态, 使爬升框架 320支撑在第一框架 100, 使驱动油缸 310伸长, 使
第一框架 100再相对于第二框架 200向上移动预定距离,再使爬升框架 320 和第二框架 200处于第一种状态; 反复进行上述过程, 使爬升框架 320和 第二框架 200之间的关系在第一种状态和第三种状态之间转换, 可以使爬 升框架 320相对于第二框架 200逐步地向上移动, 进而使第一框架 100相 对于第二框架 200向上移动一个楼层的高度。 同样, 使爬升框架 320和第 二框架 200之间的关系在第二种状态和第三种状态转换, 可以使爬升框架 320相对于第二框架 200逐步地向下移动, 使第一框架 100相对于第二框 架 200上降, 或使第二框架 200上移。
在对爬升装置工作原理描述的基础上, 以下对状态转换机构的结构及 工作原理进行描述; 为了节省篇幅, 以下仅对状态转换机构的相应状态及 状态转换原理进行描述, 对于爬升装置的工作原理不再展开说明。
请参考图 6, 该图是图 5中 I-I部分的放大结构示意图, 该图示出了实 施例三中驱动机构的结构示意图。
实施例三中, 驱动机构还包括齿条 301和与齿条 301配合的齿轮 302, 齿条 301竖向延伸, 并与第二框架 200固定, 该齿条可以是上述保证第一 框架 100和第二框架 200之间滑动配合的齿条; 与竖向延伸的齿条 301相 对应, 齿轮 302可以为圓柱齿轮, 并可旋转地安装在爬升框架 320上。 状 态转换机构包括第一棘轮机构 331、 第二棘轮机构 332、 第一转换手柄 333 和第二转换手柄 334; 棘轮机构形成状态转换机构的锁止结构。 第一棘轮 机构 331和第二棘轮机构 332均包括棘轮和与棘轮的棘齿相配合的棘爪, 形成锁止结构; 棘轮可旋转地安装在爬升框架 320上, 棘爪也可旋转在安 装在爬升框架 320上。 本例中, 第一棘轮机构 331的棘轮和第二棘轮机构 332的棘轮分别位于齿轮 302两端, 且均与齿轮 302同轴, 两个棘轮和齿 轮 302同步旋转; 第一转换手柄 333和第二转换手柄 334分别与第一棘轮 机构 331的棘爪和第二棘轮机构 332的棘爪相连, 通过第一转换手柄 333 可以改变第一棘轮机构 331中棘轮与棘爪的啮合状态, 通过第二转换手柄 334可以改变第二棘轮机构 332的棘轮与棘爪的啮合状态。 第一棘轮机构 331和锁止方向和第二棘轮机构 332的锁止方向相反。
该驱动机构中, 状态转换机构的工作原理如下:
在需要爬升框架 320相对于第二框架 200向上移动时, 通过改变第一 转换手柄 333和第二转换手柄 334的位置, 使第一棘轮机构 331的棘轮与 棘爪保持非啮合状态, 使第二棘轮机构 332的棘轮与棘爪保持啮合状态。 此时, 在驱动油缸 310收缩时, 第二棘轮机构 332允许齿轮 302旋转, 进 而使爬升框架 320和第二框架 200之间的关系为上述的第一种状态, 爬升 框架 320能够相对于第二框架 200向上移动; 在驱动油缸 310伸长时, 第 二棘轮机构 332能够阻止齿轮 302旋转, 进而使爬升框架 320和第二框架 200保持固定,使二者之间的关系为上述的第三种状态;通过驱动油缸 310 伸缩的转换, 能够使爬升框架 320和第二框架 200之间的关系在第一种状 态和第三种状态之间转换,使爬升框架 320能够逐步地相对于第二框架 200 向上移动。
在需要爬升框架 320相对于第二框架 200向下移动时, 通过改变第一 转换手柄 333和第二转换手柄 334的位置, 使第一棘轮机构 331的棘轮与 棘爪保持啮合状态, 使第二棘轮机构 332的棘轮与棘爪保持非啮合状态。 此时,在驱动油缸 310收缩时, 第一棘轮机构 331能够阻止齿轮 302旋转, 进而, 可以使爬升框架 320和第二框架 200之间的关系为上述的第三种状 态, 爬升框架 320与第二框架 200保持固定; 在驱动油缸 310伸长时, 第 一棘轮机构 331允许齿轮 302旋转, 进而使爬升框架 320能够相对于第二 框架 200向下移动, 使二者之间的关系为上述的第二种状态; 通过驱动油 缸 310伸缩的转换, 能够使爬升框架 320和第二框架 200之间的关系在第 二种状态和第三种状态之间转换, 使爬升框架 320能够逐步地相对于第二 框架 200向下移动。
根据上述描述, 本领域技术人中可以理解, 棘轮机构不限于通过转换 手柄控制棘爪与棘轮的啮合状态, 也可以通过其他方式改变棘爪与棘轮的 啮合状态; 比如, 可以通过改变棘爪与爬升框架 320之间弹性件的连接关 系改变改变棘爪与棘轮的啮合状态, 等等。 另外, 状态转换机构可以包括 向上方向锁止的第一棘条机构和向上方向锁止的第二棘条机构 , 并使第一 棘条机构和第二棘条机构均包括棘条和与棘条的棘齿相配合的棘爪, 形成 锁止结构; 棘条与第一框架固定, 也能够实现上述状态转换机构的功能;
还可以设置一个双向锁止(卡止) 的棘条机构, 实现上述状态转换机构的 功能。
请参考图 7, 该图是本发明提供的第二种状态转换机构的结构示意图。 状态转换机构包括座体 341、 销轴 342和锁止条(图中未示出)。 锁止条与 第二框架 200固定, 且竖向延伸; 同时, 锁止条设置多个竖向布置、 具有 适当间距的锁止孔; 座体 341形成容纳销轴 342的空腔; 销轴 342的周面 与该空腔内壁相配合, 在销轴 342与座体 341之间形成在水平方向上的可 滑动配合、 同时形成旋转轴线水平延伸的可旋转配合。 如图 7所示, 销轴 342相对于座体 341的滑动方向如箭头所示; 销轴 342与座体 341之间的 可旋转配合的旋转轴线为 0-0; 销轴 342相对于座体 341的滑动方向与旋 转轴线 0-0平行。 销轴 342具有与外端面和周面相交的斜面 345 , 在外端 形成一个楔形结构。 销轴 342内端部通过弹性部件 343支撑在座体 341空 腔底部。 销轴 342外端能够与锁止条的、 适当位置的锁止孔相配合, 形成 锁止结构。
上述状态转换机构的工作原理如下:
在需要爬升框架 320相对于第二框架 200向上移动时, 使销轴 342的 斜面 345朝向上方; 在弹性部件 343作用下, 销轴 342的外端伸入锁止条 的一个锁止孔中; 此时, 在驱动油缸 310收缩时, 销轴 342外端的楔形结 构能够使销轴 342克服弹性部件 343的弹力缩回, 使爬升框架 320和第二 框架 200之间的关系为上述的第一种状态, 使爬升框架 320能够相对于第 二框架向上移动; 在驱动油缸 310伸长时, 销轴 342在弹性部件 343作用 下, 向外伸出,销轴 343的外端与适当位置的锁止孔卡止,使爬升框架 320 和第二框架 200之间的关系为上述的第三种状态。 通过驱动油缸 310伸缩 的转换, 能够使爬升框架 320和第二框架 200之间的关系在第一种状态和 第三种状态之间转换, 使爬升框架 320能够逐步地相对于第二框架 200向 上移动。
在需要爬升框架 320相对于第二框架 200向下移动时, 使销轴 342的 斜面 345朝向下方; 同样, 在弹性部件 343作用下, 销轴 342的外端伸入 锁止条的一个锁止孔中; 此时, 在驱动油缸 310伸长时, 销轴 342外端的
楔形结构能够使销轴 342克服弹性部件 343的弹力缩回, 使爬升框架 320 和第二框架 200之间的关系为上述的第二种状态, 使爬升框架 320能够相 对于第二框架 200向下移动; 在驱动油缸 310收缩时, 销轴 342在弹性部 件 343作用下, 向外伸出, 销轴 343外端与适当位置的锁止孔卡止, 使爬 升框架 320和第二框架 200之间的关系为上述的第三种状态; 通过驱动油 缸 310伸缩的转换, 能够使爬升框架 320和第二框架 200之间的关系在第 二种状态和第三种状态之间转换,使爬升框架 320能够相对于第二框架 200 向下移动。
根据上述描述,可以通过适当的结构旋转该销轴 342,使爬升框架 320 可以仅在选定的方向相对于第二框架 200移动, 在相反的方向上, 使爬升 框架 320与第二框架 200保持锁止。 旋转销轴 342的方式可以根据实际需 要选择, 可以选择电控、 液压气动等方式旋转销轴。 还可以在销轴 342外 端面设置相应的孔、 凸台或其他具体结构, 并通过其他辅助工具旋转销轴 342。
销轴 342的外端不限于为楔形结构, 也可以采用适当的驱动元件在预 定的时刻使销轴 342伸出, 使销轴 342外端与锁止孔相配合, 使爬升框架 320与第二框架 200保持为上述的第三种状态; 在预定的另一时刻, 使销 轴 342缩回时, 使爬升框架 320与第二框架 200保持为上述第一种状态或 第二种状态。 驱动机构可以是液压元件, 比如液压缸, 并使液压缸一端与 座体 341相连, 另一端与销轴 342相连, 液压缸的伸缩可以控制销轴 342 的伸缩。
在爬升框架 320上设置液压缸虽然可以实现对销轴 342状态的主动控 制, 但考虑到爬升框架 320空间及销轴 342负载, 在实际应用中, 设置单 独的液压缸的难度非常大。 为了实现对销轴 342状态的主动控制, 本发明 还提供了另一种结构的状态转换机构。
请参考图 8, 该图是本发明提供的第三种状态转换机构的剖视结构示 意图。 该状态转换机构同样包括座体 341、 销轴 342和锁止条。 锁止条与 第二框架 200固定, 且竖向延伸; 同时, 锁止条设置多个竖向布置、 具有 适当间距的锁止孔; 其中, 座体 341包括导向筒体 3411、 底板 3412和外
定位筒 3413。
导向筒体 3411可以为圓筒状结构。底板 3412套装在导向筒体 3411内 壁, 外定位筒 3413套装在导向筒体 3411 内壁的外端部分, 在底板 3412 一端面与外定位筒 3413的内端面之间分别形成滑动空腔。 外定位筒 3413 也为筒状结构, 销轴 342周面与外定位筒 3413的内壁面滑动配合。 销轴 342外端为柱形结构, 并从座体 341向外伸出; 销轴 342内端包括径向向 外延伸的驱动板 3421。 同时, 外定位筒 3413中形成缩回柱塞液压缸, 缩 回柱塞液压缸的柱塞 82的外端(图 8中的右端)与驱动板 3421外端面(图 8中的左端面)相 4氏触; 底板 3412中形成外伸柱塞液压缸, 外伸柱塞液压 缸的柱塞 81的外端(图 8中的左端)与销轴 342的内端面(图 8中的右端 面)相抵触; 销轴 342外端与锁止条的锁止孔相配合。 通过控制缩回柱塞 液压缸和外伸柱塞液压缸的可以改变销轴 342的状态, 控制销轴 342的伸 缩,进而使状态转换机构进行状态转换,改变爬升框架 320与第二框架 200 之间的关系。
为了保证状态转换机构工作的可靠性, 还可以设置复位弹簧, 并使复 位弹簧的两端分别支撑在销轴 342的内端面和底板 3412上;复位弹簧不仅 可以加速销轴 342的伸出动作, 还能够在缩回柱塞液压缸和外伸柱塞液压 缸失效时, 使销轴 342保持伸出状态, 进而保证爬升装置的可靠性和安全 性。
根据上述描述, 本领域技术人员还可以通过其他结构实现改变爬升框 架 320与第二框架 200之间的关系, 使爬升框架 320能够相对于第二框架 200向上移动、 向下移动或与第二框架 200保持固定; 比如: 还可以设置 相应的单向离合机构、 凸轮机构等等, 只要能够在预定的时刻使爬升框架 320与第二框架 200保持锁止或固定, 在预定的时刻使爬升框架 320能够 相对于第二框架 200向上移动或向下移动, 就可以实现本发明的目的。
在提供上述布料杆爬升装置的基础上, 还提供了一种布料杆, 该布料 杆包括底架、杆臂和上述任一种爬升装置,所述底架与所述立柱上端固定。 由于布料杆爬升装置具有上述技术效果, 包括该爬升装置的布料杆也具有 相对应的技术效果。
以上所述仅是本发明的优选实施方式, 应当指出, 对于本技术领域的 普通技术人员来说, 在不脱离本发明原理的前提下, 还可以做出若干改进 和润饰, 这些改进和润饰也应视为本发明的保护范围。
