Description

输送管道、 臂架系统及作业设备 本申请要求于 2013 年 1 月 14 日提交中国专利局、 申请号为 201310012739.X, 发明名称为 "一种输送管道、 臂架系统及作业设备" 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。 技术领域
本发明涉及工程机械领域, 特别涉及一种输送管道, 还涉及一种臂架 系统及具有该臂架系统的作业设备。 背景技术
目前, 带有臂架系统的作业设备在工程作业中的应用越来越广泛, 比 如混凝土泵车、 布料杆、 带臂架的消防车等, 它们为作业或施工带来了极 大便利。 臂架系统通常包括臂架及设于臂架上的输送管, 臂架包括多个依 次铰接的首节臂、 中间臂(根据实际需要, 一般设置多个中间臂)和末节 臂。 与臂架相适应的, 输送管包括首节管、 与中间臂相对应的中间管 (与 多个中间臂相对应, 可以设置多个中间管)和末节管。 首节管安装在首节 臂上, 中间管安装在相应的中间臂上, 末节管安装在末节臂上, 多处管道 通过现有技术首尾相通。 该臂架系统可用于输送物料, 其工作原理是: 在 非工作状态, 臂架系统可折叠起来, 在工作状态, 臂架系统展开, 将输送 管的出口置于预定位置; 此时, 物料可从输送管进口进入, 经输送管后输 送至预定位置。
对于这类作业设备而言, 其臂架的长度是衡量其工作能力的重要指标 之一。 臂架越长, 其越能满足大型工程的需要。 随着大型工程(如摩天大 楼) 的增多及规模(如高度) 的增加, 越来越多的、 具有长臂架(一般指 臂架的长度超过 35米)的作业设备在施工中得到应用。 这些具有长臂架的 作业设备的使用, 给工程施工带来了极大方便。
然而, 在施工过程中, 这类作业设备真正需要将其臂架的长度全部用 上的时间或施工作业量只占整个工程施工的有限部分。 以 66米(在臂架竖 直展开状态下, 整车的高度) 混凝土泵车为例, 在摩天大楼的施工中, 通 常混凝土泵车在每一个工位可以完成作业半径 0到 60米左右范围以内的作 业量, 能够有效使用全部臂架系统长度的作业量所占比重低于 40%。 换而 言之, 在这类作业设备作业过程中, 臂架系统在很多情况下拥有长度盈余。 将长臂架的作业设备应用于短距离的作业场合时, 为将输送管的出口置于 预定位置, 不得不将臂架弯折起来, 输送管跟随臂架弯折, 这相当于物料 经过一段非常曲折的路径从作业设备的进口再到达预定位置。 因此, 这种 情况容易造成物料在输送管内的 "绕行" 的局面; 这种局面会导致燃油被 无意义的消耗, 易损件被无意义的磨损, 使得单个作业设备使用成本较高。 另外, 物料需要克服 "绕行" 带来的阻力, 很多能量被消耗在此过程中, 由此导致该类作业设备的作业效率并不理想。
优选地, 为了降低单个作业设备的使用成本, 在大型工程施工中也有 通过采用几款不同臂架长度的作业设备来满足各种工况下的施工需要。 但 这种方式需要客户需要足够的资金购买或租赁多款不同的此类作业设备, 对于客户而言经济性不高。 另外, 对于经济条件有限的客户来讲, 会使其 资金压力更大。
因此, 在工程施工过程中, 如何降低单个作业设备的使用成本是当前 本领域技术人亟待解决的技术问题。 发明内容
有鉴于此, 本发明提供一种臂架系统、 用于臂架系统的输送管道, 以 降低具有臂架系统的单个作业设备的使用成本。 另外, 本发明还提供一种 具有上述臂架系统的作业设备。 本发明提供了一种臂架系统, 包括臂架和输送管, 所述臂架包括依次 铰接的首节臂、 中间臂和末节臂, 所述输送管包括分别与所述首节臂、 中 间臂和末节臂对应设置的首节管、 中间管和末节管, 所述首节管、 中间管 和末节管依次连接。 所述中间管包括第一管道、 第二管道和管道切换装置。 所述第一管道的进口与所述首节管连通, 所述第二管道的出口与所述末节 管连通。 所述管道切换装置至少包括转换管道, 所述转换管道的进口与所 述第一管道的出口连通, 所述转换管道具有第一工作位置和第二工作位置, 在第一工作位置, 所述转换管道的出口与所述第二管道的进口连通, 在第 二工作位置, 所述转换管道的出口与所述第二管道的进口断开连接。
优选地, 上述系统中, 所述转换管道为旋转管。 所述旋转管的进口与 所述第一管道的出口可转动连接, 所述旋转管可转动至所述第一工作位置 和所述第二工作位置。
优选地, 上述系统中, 所述管道切换装置还包括固设于所述中间臂上 的定位板, 所述定位板上设有导向面和第一通孔及第二通孔, 所述旋转管 的出口端面与所述定位板的导向面滑动配合, 所述第二管道的进口端与所 述定位板上的第一通孔连通。 在所述第一工作位置, 所述旋转管出口通过 所述第一通孔与所述第二管道连通。 在所述第二工作位置, 所述旋转管的 出口与第二通孔连通。
优选地, 上述臂架系统还包括分叉管道, 所述分叉管道进口端固接于 所述定位板上。 在所述旋转管处于第二工作位置时, 所述分叉管道通过所 述第二通孔与所述旋转管连通。
优选地, 上述系统中, 所述管道切换装置还包括旋转轴, 所述旋转轴 的一端可转动连接于所述定位板上, 另一端固接于所述旋转管上, 且所述 旋转轴的轴线与所述旋转管的旋转轴线在同一直线上。
优选地, 上述系统中, 所述管道切换装置还包括伸缩油缸, 所述伸缩 油缸的一端铰接于所述定位板上, 另一端铰接于所述旋转管上。 所述伸缩 油缸的伸缩方向与所述旋转轴的旋转轴线垂直, 且伸缩油缸和所述旋转管 之间的铰接点与所述旋转轴的旋转轴线之间具有预定距离。
优选地, 上述系统中, 所述管道切换装置还包括伸缩油缸和连杆。 所 述连杆与所述旋转轴的轴线垂直, 并与所述旋转轴和 /或旋转管固接。 所述 伸缩油缸的一端铰接于所述定位板上, 另一端铰接于所述连杆上。 所述伸 缩油缸的伸缩方向与所述旋转轴的旋转轴线垂直。
优选地, 上述系统中, 所述定位板的导向面上设有限位台阶。 所述限 位台阶圏绕所述旋转管出口端面从第一工作位置转动至第二工作位置时在 导向面上滑动的区域边缘设置。
优选地, 上述系统中, 所述旋转管的出口端设有沿径向向外凸出的环 形凸台, 所述限位台阶内壁面上设有向内延伸的卡板, 所述环形凸台卡设 于所述卡板的内壁面。
本发明提出的臂架系统通过在中间臂上设置管道切换装置, 使得该臂 架系统能够在长距离布料和短距离布料时均具有较好的适应能力。 其工作 原理是: 在长距离布料时, 通过管道切换装置的转换管道将第一管道与第 二管道连通, 物料可通过末节管被输送至远距离的布料点。 在短距离布料 时, 管道切换装置的转换管道断开与第二管道的连接, 物料直接从转换管 道出口输出至短距离的布料点。 从上述原理可以看出, 该臂架系统既保留 了原有的长距离作业能力, 又减轻了短距离作业时的物料的 "绕行" 程度。 "绕行" 程度的减轻可有效降低作业过程中的燃油、 易损件的消耗, 并且, "绕行" 程度的减轻可使更多的能量用于做有用功, 进而为提高作业设备 的作业效率提供基础。 因此, 与现有技术相比, 利用该臂架系统可有效降 低单个作业设备的使用成本。
另一方面, 本发明还提供一种作业设备, 包括整机本体及设于整机本 体上的回转机构, 该作业设备还配设有上述任一种所述的臂架系统, 所述 臂架系统设于所述回转机构上。 优选地, 该作业设备可以为混凝土泵车或 布料杆。
与现有作业设备相比, 因该作业设备的臂架系统在长距离布料和短距 离布料时均具有相当的作业效率, 该作业设备在大型工程施工中整体作业 效率更高, 油料和易损件损耗更少, 因此, 其使用成本更低、 经济性更好。
又一方面, 本发明还提供了一种输送管道, 用于臂架系统, 该输送管 道包括第一管道、 第二管道和旋转管。 所述第一管道和第二管道相对固定 设置。 所述旋转管的进口与第一管道的出口相通并可转动连接, 所述旋转 管至少可转动至第一工作位置和第二工作位置, 在所述第一工作位置, 所 述旋转管的出口与所述第二管道的进口连通, 在所述第二工作位置, 所述 旋转管的出口与所述第二管道断开连接。
进一步地, 上述输送管道还包括定位板和分叉管道。 所述定位板和所 述第二管道、 所述第一管道三者相对固定设置。 所述定位板具有第一通孔 和第二通孔。 所述第二管道的进口与所述第一通孔相通。 所述旋转管的出 口端面与所述定位板滑动配合。 在所述第一工作位置, 所述旋转管的出口 通过所述第一通孔与所述第二管道的进口连通, 在所述第二工作位置, 所 述旋转管的出口与所述第二通孔连通。
进一步地, 上述输送管道还包括分叉管道, 所述分叉管道的进口与所 述第二通孔相通; 在所述第二工作位置, 所述旋转管的出口通过所述第二 通孔与所述分叉管道的进口连通。
与现有技术相比, 通过在第一管道和第二管道之间设置旋转管, 使得 该输送管具备远端和近端两个可选的出料端口, 并能够在这两个出料端口 间便捷地、 灵活地切换。 其工作原理是: 利用该输送管道进行长距离输送 物料时, 将旋转管出口与第二管道进口连通, 物料经第一管道、 旋转管和 第二管道输送至远端出料口。 利用该输送管道近距离输送物料时, 可转动 旋转管, 使选旋转与第二管道断开, 物料经第一管道和旋转管输送至相对 较近的近端出料口。 从上述工作原理可以看出, 该类型的输送管道即可满 足长距离输送的需要也可满足短距离输送的需要。 并且利用该输送管道短 距离输送时, 可緩解物料在输送管内的 "绕行", 进而可降低利用该输送管 道进行短距离物料输送所需的能量, 换而言之, 该输送管道可以为降低与 其配套使用的作业设备的能量消耗提供基础。 附图说明

为避免或降低长臂架系统在短距离作业时效率低、 易损件被无价值消 耗的问题, 本发明实施例提出了一种臂架系统。
参照图 1 ,其示出了本实施例提出的臂架系统的结构,该臂架系统包括: 臂架 1和输送管 2, 臂架 1包括依次铰接的首节臂 11、 中间臂 13和末节臂 12, 输送管 2包括分别与首节臂 11、 中间臂 13和末节臂 12对应设置的首 节管 21、 中间管 23和末节管 22。 例如, 固设于首节臂 11、 中间臂 13和末 节臂 12上的首节管 21、 中间管 23和末节管 22。 其中, 首节管 21、 中间管 23和末节管 22依次连接, 中间管 23包括第一管道 231、 第二管道 233和 管道切换装置 3。 第一管道 231的进口与首节管 21连通, 第二管道 233的 出口与末节管 22连通。 管道切换装置 3至少包括转换管道, 转换管道的进 口与第一管道 231 的出口连通。 转换管道具有第一工作位置和第二工作位 置: 在第一工作位置, 转换管道的出口与第二管道 233 的进口连通; 在第 二工作位置, 转换管道的出口与第二管道 233 的进口断开连接, 其结构示 例可参考图 1和图 2所示。
该臂架系统的工作原理是: 在长距离布料时, 通过管道切换装置 3 的 转换管道将第一管道 231与第二管道 233连通, 物料可通过末节管 22被输 送至远距离的布料点。 在短距离布料时, 管道切换装置 3 的转换管道断开 与第二管道 233的连接, 物料直接从转换管道出口输出至短距离的布料点。
从上述原理可以看出, 本实施例的臂架系统既保留了原有的长距离作 业能力, 又减轻了短距离作业时的物料的 "绕行" 程度, 而 "绕行" 程度 的减轻可有效降低作业过程中的燃油、 易损件的消耗, 并且 "绕行" 程度 的减轻可使更多的能量用于做有用功, 进而为提高作业设备的作业效率提 供基础。 因此, 与现有技术相比, 利用本实施例的臂架系统可有效降低单 个作业设备的使用成本。
上述臂架系统通过在中间臂 13上设置管道切换装置 3 , 使得该臂架系 统能够在长距离布料和短距离布料时均具有较好的适应能力。
需要说明的是, 中间臂 13可以包括一个臂节或多个臂节。 转换管道可 以为任意的管道, 只要其进口与第一管道连通, 其出口可选择性地与第二 管道连通或断开即可。
为方便管道切换, 上述实施例中的转换管道可以为旋转管 31。 参照图 2至图 3 , 其示出了本实施例臂架系统中管道切换装置与其它管道的连接结 构, 其中, 旋转管 31的进口与第一管道 231的出口可转动连接, 旋转管 31 可转动至第一工作位置和第二工作位置。
需要指出的是, 旋转管 31可为 S形弯管, 其示例结构及设置方式还可 参考图 3、 图 4、 图 5、 图 6和图 9。 优选地, 旋转管 31还可以为反 Z形管, 示例结构可参考图 10。
根据上述描述, 可以理解, 旋转管 31可以有多种示例结构, 只要能够 通过旋转在第一工作位置和第二工作位置进行切换即可。
为使改善该臂架系统的受力及更加顺畅的切换管道, 可对管道切换装 置 3做进一步改进, 例如, 管道切换装置 3还包括固设于中间臂 13上的定 位板 33 , 其示例设置可参考图 2至图 8。 定位板 33的一侧面形成导向面, 旋转管 31的出口端面与定位板 33的导向面滑动配合。 需要说明的是, 这 里所说的导向面是指定位板 33上与旋转管 31的出口端面相对的侧面。
该导向面与旋转管 31的出口端面贴合, 形成可滑动配合, 这样使旋转 管 31可相对于定位板 33滑动, 在第一工作位置和第二工作位置之间切换。
定位板 33上可以设有两个通孔——第一通孔 331、 第二通孔 332, 第 二管道 233的进口端与两个通孔之一连通。 在第一工作位置, 旋转管 31出 口通过其中一个通孔与第二管道 233连通, 在第二工作位置, 旋转管 31的 出口与另一个通孔连通。 例如: 在第一工作位置时, 旋转管 31通过第一通 孔 331与第二管道 233连通;在第二工作位置时,旋转管 31与第二通孔 332 连通。
另外, 定位板 33可以固定于中间臂 13上, 它可以作为一个支点, 为 第二管道 233和旋转管 31提供一定的支撑力,改善它们的受力。优选的是, 为控制物料从第二通孔 332输出时的流动方向, 可考虑在第二通孔 332出 口侧设置分叉管道 234。同时,分叉管道 234可根据需要设置成硬管或软管。
为进一步改善旋转管 31的受力, 使其转动更顺畅, 还可以设置旋转轴
32, 旋转轴 32的一端可转动地连接于定位板 33上, 另一端固接于旋转管 31上, 且旋转轴 32与旋转管 31的进口同轴设置,旋转轴 32的示例设置可 参考图 2至图 6。
为实现管道切换的自动化,还可以设置伸缩油缸 34,伸缩油缸 34的一 端可以通过油缸座 38铰接于定位板 33上, 另一端铰接于旋转管 31上, 伸 缩油缸 34的伸缩方向与旋转轴 32的旋转轴线垂直, 且伸缩油缸 34与旋转 管 31之间的铰接点与旋转轴 32的轴线之间具有预定距离。 这里, 设置预 定距离是为了使伸缩油缸 34的端部与油缸座 38、 旋转轴 32之间的位置关 系满足驱动旋转管 31旋转运动的需要。
需要说明的是, 并非一定要将伸缩油缸 34设置成与旋转轴 32的旋转 轴线垂直设置才能实现。 实际上的要求是, 伸缩油缸 34能够提供一个平行 于导向面的分力以驱动旋转管 31转动。 如果伸缩油缸 34与旋转轴 32的旋 转轴线不垂直设置, 那么伸缩油缸 34的端部与油缸座 38、 旋转管 31的连 接关系应能满足驱动旋转管 31旋转运动的需要。 通过伸缩油缸 34驱动旋 转管 31转动, 从而实现位置切换, 可有效降低人工的工作量, 并提高工作 效率。
优选地, 为方便生产, 伸缩油缸 34可不直接与旋转管 31铰接, 可再 增加与旋转轴 32垂直并固接的连 4干 35 , 将伸缩油缸 34的一端通过油缸座 38铰接于定位板 33上, 另一端铰接于连杆 35上, 伸缩油缸 34通过连杆 35驱动旋转管 31转动, 这样做可以改善旋转管 31的受力。 优选地, 如果 需要进一步改善管道切换装置的受力,可将连杆 35的一端固设于旋转管 31 的出口端, 在连杆 35受到伸缩油缸 34的作用力时,旋转管 31和旋转轴 32 可同时分担部分作用力, 避免将所有作用力集中在一个部件上。
为限定旋转管 31 的转动范围, 方便旋转管 31 的出口与第一通孔 331 或第二通孔 332对准, 可在定位板 33导向面上设置限位台阶 36, 限位台阶 36圏绕旋转管 31出口端面从第一工作位置转动至第二工作位置时在导向面 上滑动的区域边缘设置。 换言之, 限位台阶 36圏绕住旋转管 31 出口端面 从第一工作位置转动至第二工作位置时在定位板 33上所滑过的面积。
为使旋转管 31的出口与定位板 33的接触始终保持紧密, 还可以在旋 转管 31的出口设置沿其径向向外凸出的环形凸台 39, 限位台阶 36上设有 卡板 37, 环形凸台 39卡设于定位板 33的导向面和卡板 37的内壁面之间, 环形凸台 39和卡板 37的示例设置可参考图 4和图 7。
另一方面, 本发明实施例还提供了一种作业设备, 该作业设备包括整 机本体 10及设于整机本体 10上的回转机构 30 , 该作业设备还包括上述任 一实施例所述的臂架系统 20, 臂架系统 20设于回转机构 30上。 这里的作 业设备可以为混凝土泵车或者布料杆或者带臂架的消防车。
根据图 11-1和 11-2可以看出来(图 11-1为现有作业设备在短距离作业 时的情形, 图 11-2 为本发明实施例提供的作业设备在短距离作业时的情 形), 与现有作业设备相比, 在短距离作业时, 该作业设备减少了物料在输 送管内的 "绕行", 因此其在短距离作业时效率更高, 油料消耗更少, 易损 件损耗更少, 使用寿命更长。
又一方面, 本发明实施例还提供了一种输送管道, 该输送管道包括第 一管道 231、 第二管道 233和旋转管 31。 第一管道和第二管道相对固定设 置, 可以固定在臂架系统的预定中间臂、 首节臂或末节臂上。 旋转管 31的 进口与第一管道 231的出口相通并可转动连接, 旋转管 31至少可转动至第 一工作位置和第二工作位置, 在第一工作位置, 旋转管 31的出口与第二管 道 233的进口连通, 在第二工作位置, 旋转管 31的出口与第二管道 233断 开连接。 该输送管道在第一工作位置可满足长距离输送的需要, 在第二工 作位置可满足短距离输送的需要。 并且, 利用该输送管道短距离输送时, 可緩解物料在输送管内的 "绕行", 进而可降低利用该输送管道进行短距离 物料输送所需的能量, 换而言之, 该输送管道可以为降低与其配套使用的 作业设备的能量消耗提供基础。
需要指出的是,旋转管 31可以与上述臂架系统中的旋转管相同,进而, 也可以有多种选择, 在此不再赘述。
上述实施例中, 输送管道还可包括定位板 33 , 定位板 33 和第二管道
233、 第一管道 231三者相对固定设置。 定位板 33具有第一通孔 331和第 二通孔 332; 第二管道 233的进口与第一通孔 331相通。 其中, 旋转管 31 的出口端面与定位板 33滑动配合。 在第一工作位置, 旋转管 31的出口通 过第一通孔 331与第二管道 233的进口连通; 在第二工作位置, 旋转管 31 的出口与第二通孔 332连通。
在一优选实施例中, 该输送管道还可包括定位板 33和分叉管道 234; 第二管道 233、 定位板 33和第一管道 231三者相对固定设置。 定位板 33具 有第一通孔 331和第二通孔 332。第二管道 233的进口与第一通孔 331相通, 分叉管道 234的进口与第二通孔 332相通。 旋转管 31的出口端面与定位板 33滑动配合。在第一工作位置,旋转管 31的出口通过第一通孔 331与第二 管道 233的进口连通,在第二工作位置,旋转管 31的出口通过第二通孔 332 与分叉管道 234的进口连通。 这样, 通过设置定位板 33 , 切换工作位置时, 旋转管 31的出口端面在定位板 33的表面滑动, 这样可使工作位置的切换 更顺畅、 更方便。
另外, 通过设置分叉管道 234可以根据需要调节物料经第二通孔 332 后流出的方向。
优选地, 根据该输送管道的上述优点, 可以理解的是, 在臂架系统上 设置该输送管道能够为提升臂架系统近距离作业时的效率提供基础。
以上所述仅为本发明的较佳实施例而已, 并不用以限制本发明, 凡在 本发明的精神和原则之内, 所作的任何修改、 等同替换、 改进等, 均应包 含在本发明的保护范围之内。
工业实用性
本发明提供的用于臂架系统的输送管道具有两个出料口, 能够分别用 于长距离布料和短距离布料, 可避免短距离布料时混凝土在输送管内 "绕 行" 而产生的危害, 从而降低具有臂架系统的单个作业设备的使用成本。 因此, 本发明的输送管道、 设置该输送管道的臂架系统、 以及设置有该臂 架系统的作业设备具有工业实用性。
