本申请要求于 2010 年 02 月 05 日提交中国专利局、 申请号为 201010111843.0、发明名称为"一种混凝土泵车及其臂架装置"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
本发明涉及工程机械领域，特别涉及一种用于混凝土泵车的臂架装置。 本发明还涉及一种包括上述臂架装置的混凝土泵车。 背景技术
随着我国经济建设的快速发展， 市场对于建筑工程机械尤其是混凝土 泵车的需求日益增大。
在混凝土泵车的工作过程中， 需要通过固定于臂架上的输送管将混凝 土输送至指定位置， 并且随着输送位置的变化， 臂架需要带动输送管实现 展开、 收拢以及旋转等动作， 因此， 混凝土泵送设备中的臂架一般为多节， 且各节臂架之间能够折叠。
请参考图 1和图 2, 图 1为一种典型的混凝土泵车的臂架装置展开时 的结构示意图； 图 2为一种典型的混凝土泵车在臂架装置折叠时的结构示 意图。
在一种典型的混凝土泵车中， 其臂架包括第一臂架 11、 第二臂架 12、 第三臂架 13、 第四臂架 14以及第五臂架 15 , 各相邻两臂架分别通过铰接 轴铰接； 在上述各相邻两臂架之间均安装有折叠油缸 16和连杆 17 , 并通 过折叠油缸 16和连杆 17驱动一节臂架相对于与其相邻的另一臂架折叠， 以实现向不同高度位置输送混凝土； 同时， 在需要转场时， 可以将各节臂 架折叠收拢后运输。
在施工过程中需要通过臂架的伸展将混凝土输送至指定位置， 因此， 增加臂架的总长度就成为本领域的技术人员长期追求的目标。 目前， 臂架 的折叠方式通常为 R型、 RZ型或者 Z型等， 由于交通法规对于混凝土泵 车的长度和高度都有限制， 以上各种折叠方式使得臂架节数较多时， 其在 折叠后具有较长的运输长度和较高的运输高度， 从而限制了臂架总长度的 进一步提高。 因此， 如何在满足臂架折叠后的长度和高度满足运输要求的条件下， 改善混凝土泵车的车体空间布置， 提高臂架的总长度就成为本领域技术人 员亟须解决的问题。 发明内容
本发明的目的是提供一种混凝土泵车的臂架装置， 其折叠后在满足长 度和高度运输要求的条件下， 有效地提高臂架的总长度。 本发明的另一目 的是提供一种包括上述臂架装置的混凝土泵车，其车体空间布置较为合理。
为解决上述技术问题， 本发明提供一种混凝土泵车的臂架装置， 包括 多节相铰接的臂架， 任一臂架在驱动部件的作用下相对于与其相邻的臂架 转动； 还包括至少一节短臂， 所述短臂通过第一铰接轴铰接于末节臂架的 末端， 且所述短臂与所述末节臂架之间安装有第一动力部件； 所述短臂在 所述第一动力部件的作用下，相对于所述末节臂架绕所述第一铰接轴转动， 以便当所述短臂折叠时， 所述短臂位于所述末节臂架的下方， 且其轴线与 竖直平面的夹角小于或者等于 45。 。
优选地， 当所述短臂展开时， 其轴线与所述末节臂架的轴线延长线的 夹角小于或者等于 45。 。
优选地， 在折叠时所述短臂沿竖直方向位于所述混凝土泵车的尾部。 展开油缸。
优选地， 所述展开油缸的一端铰接于所述末节臂架， 且其另一端铰接 于所述短臂。
优选地， 所述展开油缸的两端分别通过铰接座铰接于所述末节臂架和 所述短臂。
优选地， 所述第一动力部件包括展开油缸， 以及分别以其第一端铰接 于所述末节臂架和所述短臂的第一连杆和第二连杆； 所述第一连杆的第二 端与所述第二连杆的第二端相互铰接， 所述展开油缸的一端固定于所述末 节臂架或者所述短臂，且其另一端与所述第一连杆或者第二连杆固定连接。
优选地， 还包括定位部件； 所述定位部件安装于所述末节臂架与所述 短臂之间， 以便可选择地固定所述短臂相对于所述末节臂架的位置。 优选地， 所述短臂包括第一短臂和第二短臂； 所述第一短臂的一端通 过第一铰接轴铰接于所述末节臂架， 且其第二端通过平行于所述第一铰接 轴的第二铰接轴与所述第二短臂铰接； 所述第一短臂与所述末节臂架之间 安装有第一动力部件， 以便所述第一短臂相对于所述末节臂架绕所述第一 铰接轴向下转动，所述第一短臂与所述第二短臂之间安装有第二动力部件， 以便所述第二短臂相对于所述第一短臂绕所述第二铰接轴向上转动。
本发明还提供一种混凝土泵车， 包括上述任一项所述的臂架装置。 本发明所提供的混凝土泵车的臂架装置， 包括多节相铰接的臂架以及 至少一节短臂， 短臂通过第一铰接轴铰接于末节臂架的末端； 短臂与末节 臂架之间安装有第一动力部件且短臂在第一动力部件的作用下相对于末节 臂架绕第一铰接轴转动。 当臂架装置处于工作状态时， 通过短臂与末节臂 架之间的第一动力部件， 驱动短臂绕第一铰接轴向远离末节臂架的方向转 动， 此时， 短臂与末节臂架的轴线延长线形成小于或者等于 45。 的夹角， 从而能够在现有臂架总长度的基础上增加其伸出部分的长度； 而当臂架装 置需要转移、 转场时， 通过第一动力部件驱动短臂绕第一铰接轴向靠近末 节臂架的方向向下转动， 使得短臂位于末节臂架的下方， 并使其轴线与竖 直平面之间的夹角小于或者等于 45。 ，从而有效降低了臂架装置折叠后的 高度和长度， 进而实现了在满足长度和高度运输要求的条件下， 有效地提 高臂架的总长度的目的。
在一种优选的实施方式中， 展开油缸的一端铰接于末节臂架， 且其另 一端铰接于短臂。 当展开油缸的缸杆自缸筒中伸出时， 驱动短臂相对于末 节臂架展开， 由于展开油缸的两端与短臂或者末节臂架的连接方式均为铰 接， 则在短臂的展开过程中展开油缸能够相对于短臂和末节臂架转动。 这 样， 当展开油缸的缸杆伸出至某一位置时， 短臂的轴线与末节臂架的轴线 呈 180。 夹角， 此时， 短臂完全展开至最长工作长度， 从而进一步提高了 臂架装置的有效总长度。 同时， 当展开油缸的缸杆缩回缸筒时， 由于展开 油缸的两端铰接， 也即其两端均能够具有一定角度的转动， 则当展开油缸 缩回至某一位置时， 短臂的轴线能够大体位于竖直平面内， 从而使得短臂 在折叠后能够最大限度地缩小臂架装置的总长度。 在另一种优选的实施方式中， 上述臂架装置还可以包括定位部件； 该 定位部件安装于末节臂架与短臂之间， 以便可选择地固定末节臂架与短臂 的位置。 当短臂展开或者折叠至某一适当的角度时， 可以通过定位部件固 定臂架和末节臂架之间的位置， 从而提高了装置展开和折叠的可靠性。 附图说明

为了使本技术领域的人员更好地理解本发明的技术方案， 下面结合附 图和具体实施方式对本发明作进一步的详细说明。
请参考图 3 , 图 3为本发明所提供混凝土泵车在臂架装置折叠时一种 具体实施方式的结构示意图。
在一种具体实施方式中，本发明所提供的臂架装置，用于混凝土泵车， 其包括多节相互铰接的臂架， 其中首节臂架铰接于混凝土泵车的平台上， 并能够在外力的作用下自混凝土泵车的平台上竖起， 且各节臂架均能够在 驱动部件的作用下相对于与其相邻的臂架转动， 从而使得末节臂架达到相 应的工作高度。 末节臂架的末端铰接有至少一节短臂 1 , 短臂 1通过第一 铰接轴 2与末节臂架铰接， 且两者之间安装有第一动力部件， 短臂 1在该 第一动力部件的作用下， 能够绕第一铰接轴 2转动。
当短臂 1展开时， 短臂 1的轴线与上述末节臂架的轴线延长线的夹角 需小于或者等于 45。 。 优选地， 该夹角可以为 0。 ， 也即短臂 1的轴线与 末节臂架的轴线延长线重合， 此时， 短臂与末节臂架的轴线呈 180。 夹角。 当短臂 1展开而处于该种状态时， 臂架装置的有效总长度最大， 从而显著 增加了臂架装置的工作总长度。
在某些工况中， 可能要求短臂 1沿水平方向展开， 此时， 短臂 1与末 节臂架呈特定夹角。 当短臂 1折叠时， 短臂 1位于末节臂架的下方， 且短 臂 1的轴线与竖直平面的夹角小于或者等于 45。 。 优选地， 该夹角可以为 0。 ， 也即短臂 1刚好位于竖直平面。 这样， 短臂 1在折叠时沿混凝土泵车 的车体长度方向所占空间最小， 从而有效降低了短臂 1 占用的长度空间。
显然地， 上述短臂 1的长度应满足， 在短臂 1折叠后应不与地面或者 泵车的其他部分发生干涉。 。 应理解为， 短臂 1位于末节臂架的两侧中的任一侧并与末节臂架的轴线 延长线呈小于或者等于 45。 的夹角。 相应地， 上述短臂 1折叠时与竖直平 面的夹角小于或者等于 45。 应理解为，短臂 1位于竖直平面的两侧中的任 一侧， 并与竖直平面呈小于或者等于 45。 的夹角。
上述各节臂架之间的连接方式可以通过竖直平面上的铰接轴铰接， 也 可以通过水平面上的铰接轴铰接， 当然也可以通过其他可折叠的连接方式 实现各相邻臂架之间的连接。 各节相邻的臂架之间应安装有驱动部件， 以 便驱动任一臂架相对于与其相邻的臂架转动。 该驱动部件可以为油缸、 油 缸连杆配合的方式， 也可以为本领域中常规使用的其他驱动方式。
上述各节臂架和短臂 1均可以为空心的钢架结构， 由于臂架装置在工 作过程中承受较大冲击力， 因此各节臂架以及短臂 1的材料应具有足够的 刚度和强度， 以保证工作可靠性。 显然地， 各节臂架以及短臂 1的材料也 不局限于钢材， 也可以为其他本领域中常规使用的金属材料， 其结构也不 局限于空心结构， 也可以为实心钢件或者桁架等。
上述第一铰接轴 2由于在臂架装置的工作过程中需要承受载荷， 则第 一铰接轴 2应具有足够的强度和刚度， 以保证臂架装置在施工中具有好高 的可靠性。
具体地， 上述各相邻两臂架之间以及末节臂架与短臂 1之间均可以通 过销轴连接。
显然地， 上述各节臂架和短臂 1上均安装有混凝土输送管， 搅拌后的 混凝土通过输送管输送至指定施工位置。 该输送管可以为耐磨材料制成的 柔性管， 在混凝土泵车的工作过程中， 不断有混凝土自输送管输送至指定 位置， 混凝土会对输送管的内壁造成较大的磨损， 使用耐磨材料制成的输 送管使用寿命较长， 从而节约了臂架装置的维护成本。
上述耐磨材料可以为橡胶材料， 其成本较低， 且使用性能稳定。 当然 也不局限于橡胶， 任何具有一定柔性， 能够在一定程度上弯折的耐磨材料 均可作为输送管的材料。
上述输送管可以为整体式结构， 也即各节臂架上安装的输送管为同一 根长度较长的输送管， 而不需将多根输送管通过接头连通， 从而避免了输 送管在工作过程中发生脱节， 进而提高了臂架装置的工作可靠性。
当臂架装置处于工作状态时， 通过短臂 1与末节臂架之间的第一动力 部件， 驱动短臂 1绕第一铰接轴 2向远离末节臂架的方向转动， 此时， 短 臂 1与末节臂架的轴线延长线形成小于或者等于 45° 的夹角，从而能够在 现有臂架总长度的基础上增加其伸出部分的长度；而当臂架装置需要转移、 转场时， 通过第一动力部件驱动短臂绕第一铰接轴 2向靠近末节臂架的方 向转动， 使得短臂 1位于末节臂架的下方， 且其轴线与竖直平面之间的夹 角小于或者等于 45。 ， 从而有效降低了臂架装置折叠后的高度和长度， 进 而实现了在满足长度和高度运输要求的条件下， 有效地提高臂架的总长度 的目的。
上述臂架装置可以具体包括依次铰接的第一臂架 31、第二臂架 32、第 三臂架 33、第四臂架 34以及第五臂架 35 ,所述第五臂架 35的末端通过所 述第一铰接轴 2与所述短臂 1铰接。 则前文中所述的末节臂架为此处的第 五臂架 35 , 以上所述末节臂架的所有结构性质均适用于第五臂架 35。 由于 结构中已包括了五节臂架， 臂架的总长度已基本处于极限状态， 在此种状 态下将短臂 1通过第一铰接轴 2铰接于第五臂架 35的末端，从而使得臂架 装置在伸展的总长度得到进一步的提高， 具有较大的实际使用意义。
显然地， 本发明所提供的臂架装置不局限于包括五节臂架， 根据实际 工作中的使用要求以及加工制造等方面的技术水平， 臂架节数可以少于五 节， 臂架装置中的臂架节数不应受到本发明的限制。
请参考图 4至图 7 , 图 4为本发明所提供混凝土泵车的臂架装置展开 时一种实施方式的局部结构示意图； 图 5为图 4中 A部分的放大图； 图 6 为本发明所提供混凝土泵车的臂架装置折叠时一种具体实施方式的局部结 构示意图； 图 7为图 6中 B部分的放大图。
在另一种具体实施方式中， 以上述五节臂架的臂架装置为例， 上述第 一动力部件为安装于第五臂架 35与短臂 1之间的展开油缸 4。 油缸为本领 域中较为常规的动力装置， 其输出动力平稳， 且成本较低。
上述展开油缸 4的一端铰接于第五臂架 35 ,且其另一端铰接于短臂 1。 当展开油缸 4的缸杆 42 自缸筒 41中伸出时， 驱动短臂 1相对于第五臂架 35展开， 由于展开油缸 4的两端与短臂 1或者第五臂架 35的连接方式均 为铰接， 则在短臂 1的展开过程中展开油缸 4能够相对于短臂 1和第五臂 架 35转动。 这样， 当展开油缸 4的缸杆 42伸出至某一位置时， 短臂 1的 轴线与第五臂架 35的轴先可以呈 180。 夹角， 此时， 短臂 1完全展开至最 长工作长度， 从而进一步提高了臂架装置的有效总长度。 同时， 当展开油 缸 4的缸杆 42缩回缸筒 41时， 由于展开油缸 4的两端铰接， 也即其两端 均能够具有一定角度的转动， 则当展开油缸 4缩回至某一位置时， 短臂 1 的轴向能够大体位于竖直平面内， 从而使得短臂 1在折叠后能够最大限度 地缩小臂架装置折叠后的长度。
上述展开油缸 4可以通过缸杆 42铰接于短臂 1 , 此时， 通过缸筒 41 铰接于第五臂架 35; 也可以通过其缸杆 42铰接于第五臂架 35 , 此时， 通 过缸筒 41铰接于短臂 1。
上述展开油缸 4的缸杆 42和缸筒 41可以分别通过设置于短臂 1和第 五臂架 35上的铰接座 5与短臂 1和第五臂架 35铰接， 以便提高安装可靠 性， 并简化安装过程。 上述展开油缸 4可以通过连杆机构与短臂 1和第五臂架 35铰接。具体 地， 上述连杆机构可以包括第一连杆和第二连杆， 第一连杆的一端铰接于 短臂 1 , 其另一端与第二连杆的一端铰接， 第二连杆的另一端铰接于第五 臂架 35。
通过展开油缸 4和连杆机构的共同作用， 以实现短臂 1相对于第五臂 架 35的转动， 连杆机构动力传递稳定， 且展开油缸 4传动的动力较大， 从 而保证了臂架装置的工作可靠性。 上述动力部件还可以包括液压马达， 该 液压马达的输出轴通过联轴器与第一铰接轴 2连接， 此时， 第一铰接轴 2 固定于短臂 1。 当液压马达工作时， 其输出轴将动力通过联轴器传递给第 一铰接轴 2, 并通过第一铰接轴 2带动短臂 1转动， 该种结构的结构紧凑， 空间占用小。
在本发明所提供的臂架装置中还可以包括定位部件； 该定位部件安装 于所述第五臂架 35与短臂 1之间， 以便可选择地固定短臂 1与第五臂架 35的相对位置。
该定位部件也不局限于安装于第五臂架 35和短臂 1之间，理论上来讲， 也可以安装于第五臂架 35上的适当位置或者臂架 1上的适当位置。
还可以对本发明所提供的臂架装置进行进一步的改进。
在另一种具体实施方式中， 本发明所提供的短臂 1还可以进一步包括 第一短臂和第二短臂， 该第一短臂的一端通过第一铰接轴 2铰接于第五臂 架 35 , 第一短臂的第二端通过大体平行于第一铰接轴 2的第二铰接轴与第 二短臂铰接； 第一短臂与末节臂架之间安装有第一动力部件， 并在第一动 力部件的作用下绕第一铰接轴 2向下运动， 第一短臂与第二短臂之间安装 有第二动力部件， 第二短臂在第二动力装置的作用下相对于第一短臂绕第 二铰接轴向上转动。
显然地， 上述第一短臂和第二短臂在折叠时均位于末节臂架的下方。 将短臂设置成相互铰接并能够相对转动的两部分， 有助于进一步在保 证折叠后高度要求的条件下提高臂架装置的有效总长度。
从理论上讲， 在满足折叠后高度和长度要求的条件下， 上述短臂 1也 可以包括相互铰接的多节。 上述第二动力部件可以为两端分别铰接于第一短臂和第二短臂的油 缸。 显然地， 上述第二动力部件也不局限于油缸， 只要能够实现第二短臂 相对于第一短臂摆动，第二动力部件的具体形式不应受到本说明书的限制。
除了上述臂架装置， 本发明还提供一种包括上述臂架装置的混凝土泵 车， 该混凝土泵车其他各部分的结构请参考现有技术， 在此不再赘述。
以上对本发明所提供的一种混凝土泵车及其臂架装置进行了详细介 实施例的说明只是用于帮助理解本发明的方法及其核心思想。 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 可以对本发明进行若干改进和修饰， 这些改进和修饰也落入本发明权利要 求的保护范围内。
