Description

一种臂架装置及混凝土泵车 本申请要求于 2012 年 02 月 24 日提交中国专利局、 申请号为 201210044355.1、发明名称为"一种臂架装置及混凝土泵车 "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 本发明涉及泵送技术, 特别是涉及混凝土泵送技术, 尤其涉及一种臂 架装置。 本发明还涉及一种具有上述臂架装置的泵车。 背景技术
随着我国经济建设的快速发展, 市场对于建筑用泵送机械尤其是混凝 土泵车的需求日益增大。
混凝土泵车中的臂架一般为多节, 且各节臂架之间能够折叠。 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、 折叠 以及旋转等动作。
如图 1 所示, 为一种典型的混凝土泵车的结构示意图。 该混凝土泵车 的臂架装置包括第一节臂架 201、 第二节臂架 202、 第三节臂架 203、 第四 节臂架 204; 其中, 混凝土泵车的转台 100通过回转支承安装于混凝土泵车 的底盘上, 转台 100可相对于底盘转动, 第一节臂架 201铰接于转台 100 上, 且上述各节臂架依次铰接, 相邻两臂架之间设置驱动油缸以驱动相邻 两臂架转动, 从而实现臂架的打开和折叠。
参照图 1 , 转台 100—般布置于底盘靠近驾驶室的位置, 也即底盘的前 部, 第一节臂架 201与转台 100铰接并向混凝土泵车的尾部折叠, 在转台 100与第一节臂架 201之间设置第一臂架油缸 300, 第一臂架油缸 300的两 端分别与转台 100和第一节臂架 201铰接, 且第一节臂架 201正置, 即第 一节臂架 201与转台 100的铰接轴线 A高于第一臂架油缸 201与转台 100 的铰接轴线 B; 在臂架装置处于折叠状态下时, 第一臂架油缸 300伸出以 推动第一节臂架 201进行展开动作。
根据臂架装置常用的 R型、 Z型或 RZ型折叠方式,在臂架装置处于折 叠状态下, 上述第二节臂架 202、 第三节臂架 203、 第四节臂架 204—般均 布置在第一节臂架 201的下方的布置空间中, 第二节臂架 202、 第三节臂架 203和第四节臂架 204的长度一般也小于第一节臂架 201的长度。 因此, 上 述臂架布置形式中, 除第一节臂架外的其他各节臂架的长度会受到第一节 臂架 201 长度局限; 因此, 为了增大臂架装置的展开长度, 通常需要增加 臂架的节数; 但是, 由于第一节臂架 201 下方的布置空间有限, 臂架节数 的增加数量也非常有限。
在当前混凝土泵车向超高泵送高度、 超宽布料范围的发展趋势下, 现 有技术中的臂架布置形式不能满足超长臂架的布置。 因此, 如何改进臂架 装置的折叠方式, 为超长臂架提供布置空间, 提高整个臂架装置的布料范 围, 成为本领域技术人员亟待解决的技术难题。 发明内容
基于背景技术中第一节臂架正置的技术方案, 本发明提出的臂架装置 中第一节臂架倒置, 即第一节臂架与转台的铰接点低于第一臂架油缸与转 台的铰接点。 据此, 本发明的第一个目的是提供一种臂架装置, 能够实现 超长臂架的布置, 进而提高整个臂架装置的布料范围。
本发明的第二个目的是提供一种具有上述臂架装置的泵车。
为了实现上述第一个目的, 本发明提供了一种臂架装置, 用于泵送机 械, 包括依次铰接的多节臂架, 第一节臂架能够与泵送机械的转台铰接, 转台位于泵送机械的中部, 所述第一节臂架与转台之间设有第一臂架油缸; 第一节臂架倒置, 即所述第一节臂架与转台的铰接点低于所述第一臂架油 缸与转台的铰接点; 第二节臂架与第一节臂架铰接并折叠于第一节臂架的 上方; 第二节臂架至最末节臂架均贯穿泵送机械的车体。
优选地, 所述臂架装置至少包括依次铰接的四节臂架, 第二节臂架、 第三节臂架和第四节臂架均包括两个臂节。
本发明提供的臂架装置包括依次铰接的多节臂架, 第一节臂架与泵送 机械的转台铰接, 转台位于泵送机械的中部, 第一节臂架倒置, 第二节臂 架与第一节臂架铰接并折叠于第一节臂架的上方; 第二节臂架至最末节臂 架均贯穿泵送机械的车体。 将转台设置在泵送机械的中部, 第一节臂架倒 置并向泵送机械的尾部或驾驶室方向延伸, 这样, 第二节臂架至最末节臂 架便可贯穿整个泵送机械的车体, 即沿着泵送机械的长度方向从泵送机械 的驾驶室贯穿至其尾部, 从而能够实现超长臂架的布置, 进一步提高整个 臂架装置的展开高度以扩大其布料范围。
优选方案中, 至少一节臂架由至少两个臂节铰接而成, 相邻两个臂节 之间铰接有伸缩油缸; 或者, 至少一节臂架由至少两个臂节可拆装连接而 成。 将单节较长的臂架截断为两节以上较短的臂节, 短臂节便于在臂架生 产过程中进行加工制作、 运输、 拆卸、 装配操作, 并且在布料过程中相对 于单节超长臂架, 多节短臂节可增加臂架布料的灵活性, 扩大臂架装置的 布料范围。
为了实现上述第二个目的, 本发明还提供了一种混凝土泵车, 包括位 于泵送机械的中部的转台, 该混凝土泵车具有上述的臂架装置, 所述第一 节臂架与泵送机械的转台铰接相连。 由于上述的臂架装置具有上述技术效 果, 具有该臂架装置的混凝土泵车也应具有相应的技术效果。 附图说明 图 1为现有技术中一种典型的混凝土泵车的结构示意图; 图 2为本发明一种具体实施方式所提供的臂架装置的结构示意图; 图 3为图 2中转台与第一节臂架布置的结构示意图;

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。
请参看图 2、 图 3、 图 4。 为便于公众理解, 图中还示出与臂架相连的 转台; 但应当说明的是: 本发明提供的臂装置可以不包括转台。
如图 2、 图 3、 图 4所示, 本发明实施例提供了一种臂架装置, 用于泵 送机械, 该臂架装置包括依次铰接的多节臂架; 泵送机械的转台 2设置在 底盘上并位于泵送机械的中部, 第一节臂架 11的根部与转台 2铰接; 第一 节臂架 11与转台 2之间设有第一臂架油缸 3,且第一节臂架 11与转台 2的 铰接点低于第一臂架油缸 3与转台 2的铰接点, 即第一节臂架 11倒置; 这 样, 在第一臂架油缸 3的作用下可带动第一节臂架 11翻转约 90度后进行 正常布料; 在第一节臂架 11倒置的情况下, 第一节臂架 11可向泵送机械 的尾部或驾驶室方向延伸; 第二节臂架 12与第一节臂架 11铰接并折叠于 第一节臂架 11的上方; 第二节臂架 12至最末节臂架均贯穿泵送机械的车 体, 即沿着泵送机械的长度方向从泵送机械的驾驶室贯穿至其尾部。
本发明实施例提供的臂架装置中, 应用该臂架装置的泵送机械中, 转 台 2设置在泵送机械的中部, 第一节臂架 11倒置并向泵送机械的尾部或驾 驶室方向延伸; 这样, 第二节臂架 12至最末节臂架便可贯穿整个泵送机械 的车体, 从而能够实现超长臂架的布置, 进一步提高整个臂架装置的展开 高度以扩大其布料范围。
具体的方案中, 如图 3所示, 第一节臂架 11可向车尾方向倒置。 优选方案中, 臂架装置中至少一节臂架由至少两个臂节铰接而成, 并 在相邻两个臂节之间铰接有伸缩油缸, 在伸缩油缸的作用下两个臂节能够 相互转动。 将单节较长的臂架截断为两节以上由伸缩油缸驱动的较短臂节 的情况下, 短臂节便于在臂架生产过程中进行加工制作、 运输、 拆卸、 装 配操作, 并且在布料过程中, 相对于单节超长臂架, 多节短臂节可增加臂 架布料的灵活性, 扩大臂架装置的布料范围。 另一方面, 还可以将臂架装 中至少一节臂架设置成由至少两个臂节可拆装连接而成的结构, 在该结构 中, 相邻两个臂节之间虽然不能具有相对运动, 但在臂架生产过程中, 同 样可以便于超长臂架的加工制作、 运输、 拆卸、 装配操作。
需要说明的是, 至少一节臂架由至少两个臂节铰接而成, 并在相邻两 个臂节之间铰接有伸缩油缸时, 在伸缩油缸的作用下可带动相邻两个臂节 转动。 在多节臂架均为跨越整个车体的超长臂架时, 这会降低臂架装置的 布料灵活性; 但通过上述设置方式, 使至少一节臂架包括至少两个臂节铰 接的结构, 可在一定程度上提高其布料灵活性。
优选方案中, 伸缩油缸可收容于臂节内; 这种方案中, 臂架处于折叠 状态时, 伸缩油缸不会占用臂架布置空间; 进而可避免臂架在动作过程中 的干涉现象, 并且伸缩油缸不会影响输送管的安装和布置。 当然, 伸缩油 缸也不局限于收容于臂节内, 还可以位于臂节外部。
具体的方案中, 如图 3所示, 第一节臂架 11可以包括第一臂节 111和 第二臂节 112, 第一臂节 111和第二臂节 112铰接而成, 即第一臂节 111和 第二臂节 112铰接相连;并在第一臂节 111和第二臂节 112之间铰接有伸缩 油缸 113; 即伸缩油缸 113的两端分别与第一臂节 111和第二臂节 112铰接 相连; 这样, 在伸缩油缸 113 的作用下, 两个臂节能够相互转动。 优选的 方案中, 伸缩油缸 113收容于第一臂节 111内和 /或第二臂节 112内。
具体的方案中, 如图 4所示, 第二节臂架 12可以包括第三臂节 121和 第四臂节 122; 第三臂节 121和第四臂节 122铰接而成, 即第三臂节 121和 第四臂节 122相连, 并在两个臂节之间设置伸缩油缸以驱动两个臂节实现 转动动作, 即使该伸缩油缸的两端分别与第三臂节 121和第四臂节 122铰 接。
具体的方案中, 臂架装置至少包括依次铰接的四节臂架; 其中, 第三 节臂架 13为折弯臂架; 即该第三节臂架 13 包括第一直臂段、 拐弯段和第 二直臂段; 第一直臂段与第二节臂架 12铰接并折叠于第二节臂架 12的下 方, 拐弯段优选设置在转台 2所在的位置, 第四节臂架 14与第二直臂段铰 接并折叠于第二直臂段的上方。 在臂架装置 1折叠时, 第一直臂段与第二 臂架 12 占据同一列布置空间, 第二直臂段与第四臂架 14 占据另一列布置 空间, 且拐弯段布置在两列布置空间之间。 这种臂架布置方式, 使得整套 臂架装置 1结构紧凑, 并充分利用了第二节臂架 12下方位于转台 2前端的 布置空间, 使得空间利用比较合理。
在优选方案中, 第三节臂架 13可以由两个臂节通过可拆装方式实现连 接。 如图 8、 图 9所示, 图 8为第三节臂架 13可拆装连接的结构示意图, 图 9为图 8中 A处的放大图。 参照附图, 第三节臂架 13包括第五臂节 131 和第六臂节 132; 第五臂节 131和第六臂节 132之间可拆装连接, 且两个臂 节之间的可拆装连接位置设于第二直臂段。 具体的, 在第五臂节 131 和第 六臂节 132上之间通过销轴 133连接, 然后还设置连接板 134, 并分别通过 螺栓 135分别将连接板 134固定在第五臂节 131和第六臂节 132上; 即使 第五臂节 131和第六臂节 132均与连接板 134固定, 从而实现两个臂节的 可拆装连接。 可拆装连接操作筒单, 可便捷地实现两个臂节的装配和拆下, 两个臂节可拆装的连接能够方便超长臂架的加工制作、 运输、 拆卸、 装配 操作。
具体的方案中, 臂架装置至少包括依次铰接的五节臂架; 第五节臂架 15可与第四节臂架 14铰接并折叠于第四节臂架 14的上方。
进一步的方案中, 第五节臂架 15为臂架装置的最末节臂架, 即该臂架 装置包括五节臂架。 如图 3至图 7所示, 第一节臂架 11包括第一臂节 111、 第二臂节 112; 第二节臂架 12包括第三臂节 121、 第四臂节 122; 第三节臂 架 13包括第五臂节 131、 第六臂节 132; 第四节臂架 14包括第七臂节 141、 第八臂节 142; 第五节臂架 15包括前端臂节 151、 中部臂节 152和末端臂 节 153。 第五节臂架 15中, 前端臂节 151与中部臂节 152可拆装连接而成; 中部臂节 152和末端臂节 153铰接而成, 并在该两个臂节之间铰接有伸缩 油缸, 即在中部臂节 152与末端臂节 153之间铰接有伸缩油缸; 或者, 三 个臂节依次铰接而成, 并在相邻两个臂节之间铰接有伸缩油缸, 即前端臂 节 151、 中部臂节 152和末端臂节 153依次铰接相连, 且在前端臂节 151和 中部臂节 152之间、 中部臂节 152和末端臂节 153之间均铰接有伸缩油缸。 具体的方案中,臂架装置至少包括依次铰接的六节臂架, 该臂架装置 1 包括第一节臂架 11、 第二节臂架 12、 第三节臂架 13、 第四节臂架 14、 第 五节臂架 15及第六节臂架;六节臂架中至少一节臂架包括不少于两个臂节。
本发明对臂架装置 1 的臂架的数量、 布置方式不作限定, 凡转台位于 泵送机械的中部, 第一节臂架与泵送机械的转台铰接, 第一节臂架倒置, 第二节臂架与第一节臂架铰接并折叠于第一节臂架的上方; 第二节臂架至 最末节臂架均贯穿泵送机械的车体均应在本发明的保护范围内。
上述实施例中,第一节臂架 11向车尾方向倒置,本发明并不局限于此, 第一节臂架 11还可向车头方向倒置, 如图 10、 图 11所示; 这两种方案均 应在本发明的保护范围内, 即第一节臂架 11 向车尾方向倒置和第一节臂 架 11向车头方向倒置的方案应在本发明的保护范围内。
本发明还提供了一种混凝土泵车, 该混凝土泵车具有上述的臂架装置。 由于上述的臂架装置具有上述技术效果, 具有该臂架装置的混凝土泵车也 应具有相应的技术效果, 在此不再做详细介绍。
