技术领域
本发明涉及一种输送粘稠物料的输送机械, 特别涉及一种轮式布料机 械。
背景技术
由于泵车使用方便, 功能强大, 已经成为应用广泛的轮式布料机械。 请参考图 1 , 该图是现有技术一种泵车的整体结构示意图, 该图示出泵车 处于预定的工作状态时的结构。泵车一般包括行驶系统 100、泵送系统 300, 和臂架系统 200。 行驶系统 100为汽车底盘, 汽车底盘包括车架和安装在 车架上的多个车轮总成; 汽车底盘可以保证泵车行驶的安全, 满足泵车转 场需要。泵送系统 300,和臂架系统 200均安装在汽车底盘上。泵送系统 300, 包括驱动油缸、 输送缸、 换向阀和料斗, 能够将物料以一定的压力泵出。 臂架系统 200包括多节臂杆和输送管道, 多节臂杆包括根端臂、 末端臂和 位于二者之间的其他臂杆, 各臂杆通过水平铰接轴顺序铰接相连; 根端臂 的内端通过回转机构与汽车底盘底架相连; 输送管道的内端与泵送系统 300,的泵送口相通, 外端沿臂杆延伸到末端臂外端。
泵车通常还会设置与底盘相连的支腿机构。 支腿机构包括基本横向延 伸的悬臂及能够基本在竖向延伸的支撑臂, 悬臂和支撑臂还可以分别进行 伸缩, 以实现支撑状态和非支撑状态的转换。
泵车具有行驶状态和工作状态两种状态。 在行 ^史状态, 泵送系统 300, 停止泵送物料, 臂架系统 200收拢在汽车底盘上方; 支腿机构的支撑臂收 缩, 支腿机构与地面分离, 行驶系统 100支撑在地面上; 此时, 利用行马史 系统 100 (汽车底盘) 能够进行转场操作, 使泵车从一个施工场地到达另 一个施工场地。 在预定的工作状态, 汽车底盘水平放置, 支腿机构的支撑 臂伸出, 支腿机构支撑在地面上, 使行驶系统 100的车轮与地面分离; 支 腿机构可以为泵车提供较大的支撑跨度, 以提高泵车的工作稳定性。 使臂 架系统 200展开, 根端臂与汽车底盘相连, 末端臂的外端向外伸出。 泵送 系统 300,通过泵送口、输送管道将混凝土或其他物料输送到末端臂的外端。 通过改变相邻臂杆之间的夹角, 可以改变末端臂外端的位置, 使物料到达 预定的位置, 在预定的范围进行布料。
如图 1所示, 在泵车处于预定的工作状态, 进行布料操作时, 汽车底 盘水平放置, 占用了施工场地的相应空间。 在当前施工要求不断提高, 施 工场地日益紧凑的情况下, 汽车底盘占用空间增加了泵车的使用场地, 降 低了泵车的适应能力; 在^艮多情形, 由于施工场地无法容纳汽车底盘, 不 得不改变施工方式, 甚至改用其他机械实现预定施工操作。 不仅泵车存在 该问题, 具有行驶系统的轮式布料架或其他轮式布料机械也存在相同的问 题。 因此, 如何提高轮式布料机械的适应能力是当前本领域技术人员需要 解决的技术问题。

该轮式布料机械还包括四个支腿机构 600。 支腿机构 600本身可以为 现有技术, 可以根据实际情况选择伸缩式、 垂直轴铰接、 水平轴铰接中的 一种或多种的结合。 支腿机构 600的内端与布料机架 400相连; 本例中, 各支腿机构 600的悬臂内端与布料机架 400的固定部件 402通过竖向铰接 轴铰接相连; 这样, 各支腿机构 600均可以绕回转机构的回转中心线相对 于布料机架 400进行摆动。 本例中, 在行驶状态, 向前延伸的两个支腿机 构 600的悬臂为固定式结构, 向后延伸的两个支腿机构 600的悬臂包括两 节, 形成伸缩式结构。
主行 3史系统 100包括多个车桥总成。 多个车桥总成直接安装在向前延 伸的两个支腿机构 600上; 为了区别起见, 安装有车轿总成的两个支腿机 构 600分别称为驱动支腿机构, 并用标记 601表示。 本例中, 主行驶系统 100 的多个车轿总成分成两组, 形成第一车桥总成组和第二车桥总成组; 第一车桥总成组的车桥总成安装在一个驱动支腿机构 601的悬臂上, 第二 车桥总成组的车桥总成安装在另一个驱动支腿机构 601的悬臂上。 多个车 桥总成可以根据现有汽车底盘的车桥布局方式设置, 也可以根据轮式布料 机械负载分布设置; 位于前部的车桥总成可以设置为具有转向功能的车桥 总成。 可以理解, 只要至少一个车桥总为具有转向功能的车桥总成, 适当 设置车桥总成的布局, 就可以实现主行驶系统 100的转向操作, 保证或提 高主行驶系统 100的灵活性。
臂架系统 200的根端臂 210的内端与布料机架 400的旋转部件 401相 连。 这样, 臂架系统 200就可以相对于支腿机构 600绕回转机构的回转中 心线旋转。 回转机构可以设置现有的驱动机构, 以驱动旋转部件 401相对 于固定部件 402旋转, 改变臂架系统 200的位置。 本例中, 根端臂 210内 端通过根端铰接轴 211与回转机构的旋转部件 401铰接相连, 形成铰接连 接结构。 该铰接连接结构相对应, 还可以设置翻转液压缸作为臂架驱动机 构, 并使翻转液压缸两端分别与根端臂 210和旋转部件 401铰接相连; 使 翻转液压缸进行伸缩动作, 可以使根端臂 210相对于旋转部件 401绕根端 铰接轴 211的轴线旋转,改变根端臂 210和布料机架 400之间的相对位置。
为了便于泵送系统 320的转场, 本实施例中, 泵送总成 300还设置有 泵机辅助行驶系统 310, 泵机辅助行驶系统 310与泵送系统 320相连; 泵 机辅助行驶系统 310也由多个车桥总成组成, 各车桥总成可以安装在泵送 系统 320的输送缸上。 在行驶状态, 泵送系统 320通过拖挂方式与布料机 架 400相连, 泵机辅助行驶系统 310支撑在路面上, 泵送系统 320的重量 作用在泵机辅助行驶系统 310上。 为了合理分配轮式布料机械的负载, 保 证行驶状态的稳定性, 实施例一中, 还设置了机架辅助行驶系统 420, 机 架辅助行驶系统 420的车桥总成安装在布料机架 400上。 在行驶状态, 布 料机架 400的重量基本作用在机架辅助行驶系统 420上。
如图 2所示, 在行驶状态, 各支腿机构 600的支撑臂收缩, 与地面分 离; 两个驱动支腿机构 601并拢, 二者的延伸方向保持平行, 并通过主行 驶系统 100支撑在路面上。 收拢后的所述臂架系统 200位于两个驱动支腿 机构 601的上方,臂架系统 200的形成的负载作用在驱动支腿机构 601上, 进而其重量作用在两个驱动支腿机构 601上。 其他两个支腿机构 602向后 延伸并拢, 二者的延伸方向也保持平行, 且分别支撑在泵送总成 300的泵 机辅助行驶系统 310的两侧上, 与路面保持分离。
这样, 在行驶状态下, 各支腿机构 600与地面保持分离, 通过主行驶 系统 100、 泵机辅助行马史系统 310和机架辅助行马史系统 420与地面接触, 可以方便地实现轮式布料机械的转场操作。
参考图 3和图 4, 在该轮式布料机械从行驶状态转换到预定的工作状 态时, 通过翻转液压缸、 起重机或其他辅助机械, 可以使臂架系统 200抬 高,使臂架系统 200与驱动支腿机构 602分离;再使两个驱动支腿机构 601 分别向两侧摆动适当角度, 再使其支撑臂伸长, 并支撑在地面上; 同时, 可以使两个支腿机构 602悬臂伸长, 再使其支撑臂伸长, 支撑在地面上, 进而使支腿机构 600支撑在地面上。 然后, 通过翻转液压缸、 起重机或其 他辅助机械, 可以使臂架系统 200相对于布料机架 400翻转适当的角度; 再通过现有的方式, 可以使臂架系统 200相对于布料机架 400绕回转机构 的回转中心旋转, 也可以通过现有方式, 使臂架系统 200的各臂杆展开, 以支腿机构 600及布料机架 400为基础, 进行布料作业。
在预定的工作状态, 支腿机构 600可以提供预定的支撑力, 保证轮式 布料机械的支撑跨度, 提高布料作业的稳定性。 由于主行驶系统 100位于 驱动支腿机构 601的悬臂的下方, 主行驶系统 100占用的空间与驱动支腿 机构 601 占用的空间重叠, 进而可以减小预定的工作状态下轮式布料机械 占用的场地; 在施工空间较小的场地也能够进行布料作业, 进而能够提高 轮式布料机械的适应性。
可以理解, 布料机架 400与根端臂 210的内端也可以固定相连, 以提 高轮式布料机械的整体钢性; 此时, 可以使驱动支腿机构 601通过一个横 向铰接轴与布料机架 400相连(要实现支腿机构的支撑功能,布料机架 400 需要根据现有技术设置卡止结构, 以在工作状态, 使支腿机构的内端卡在 布料机架 400的适当位置); 这样, 在驱动支腿机构 601支撑在地面上, 可 以使布料机架 400绕横向铰接轴相地于驱动支腿机构 601旋转, 进而在翻 转臂架系统 200时, 使臂架系统 200与布料机架 400同时翻转。 进而, 在 行驶状态下, 布料机架 400回转机构的回转中心线与水平面之间的关系不 限于保持垂直, 回转中心线可以与水平面之间形成预定的锐夹角, 也可以 保持平行, 还可以根据实际需要确定。
在行驶状态, 主行驶系统 100的多个车桥总成与路面接触, 支撑在路 面上。 主行驶系统 100可以采用现有的动力系统, 通过现有的方式分配动 力; 也可以使至少一个车桥总具有独立的驱动机构; 另外, 也可以通过其 他动力装置或机械拖动主行驶系统 100。
本实施例中, 主行驶系统 100包括多个车桥总成, 多个所述车桥总成 分别安装在驱动支腿机构 601的悬臂上; 多个所述车桥总成中至少有一个 转向车桥总成。 在行驶状态, 多个车桥总成通过驱动支腿机构 601相连, 驱动支腿机构 601承担主行驶系统车架的功能, 转向车桥总成可以实现主 行驶系统 100的转向, 方便轮式布料机械的转场; 在预定的工作状态, 驱 动支腿机构 601承担支撑功能。 现有技术中, 主行驶系统 100的车架仅能 够在行驶状态发挥相应作用, 各支腿机构均仅能够在预定的工作状态发挥 支撑作用。 该轮式布料机械中, 支腿机构 600的驱动支腿机构 601能够分 别在两种状态发挥不同的作用, 具有两种功能; 进而能够更好地利用驱动 支腿机构 601 ; 由于可以省略现有汽车底盘的车架, 进而能够在保持布料 能力不变的情况下, 降低轮式布料机械的重量和制造成本, 减小转场过程 中的能量消耗, 降低使用成本。 重要是: 利用该技术方案获得的轮式布料 机械, 通过降低其设计时速, 可以形成《机动车运行安全技术条件》 中所 称的轮式专用机械车辆, 在保证安全运行的前提下, 该轮式专用机械车辆 可以具有更大的外轮廓尺寸; 这就能够突破现有技术中汽车底盘对现有泵 车等轮式布料机械布料半径的限制; 进而,可以使臂架系统具有更大尺寸, 使布料半径增加, 提高其布料能力; 在轮式布料机械包括泵送系统 320的 情况下, 该技术方案还能够使泵送系统 320具有更大尺寸, 进而为提高其 泵送能力提供前提。 进而能够为提高泵送能力和布料半径提供前提。
另外, 主行驶系统 100也可以使用现有的汽车底盘结构, 可以使主行 驶系统 100包括车架和安装在车架上的多个车桥总成, 并使车架安装在至 少一个支腿机构 600的悬臂上(该支腿机构形成上述驱动支腿机构 601 ); 这样, 在预定的工作状态, 也可以使整个汽车底盘与驱动支腿机构 601保 持一定程度的重叠, 减小预定的工作状态轮式布料机械占用的场地, 实现 本发明的目的。
另外, 也可以使主行驶系统 100 (汽车底盘或各车桥总成)通过可拆 卸机构安装在驱动支腿机构 601的悬臂上; 这样, 在轮式布料机械转换到 工作状态时, 可以使主行驶系统 100与驱动支腿机构 601分离, 将主行马史 系统移动到其他位置; 这不仅能够进一步减小主行驶系统 100占用空间, 也能够为轮式布料机械的操作提供便利。
本例中, 各支腿机构 600的内端均通过竖向铰接轴与布料机架 400铰 接相连; 同时, 使车桥总成与驱动支腿机构 601的悬臂之间通过竖向铰接 轴相连; 这样,可以更好地调整车桥总成与驱动支腿机构 601之间的角度, 使两个驱动支腿机构 601上的车桥总成的行驶方向保持平行, 进而方便轮 式布料机械的转场操作。
本实施例中, 包括泵送系统, 进而, 工作状态为能够进行泵送和布料 的状态。 本实施例提供轮式布料机械不限于以上述工作状态进行工作, 可 以根据实际需要以另一种工作状态进行泵送和布料。如: 在布料范围较小, 不需要臂架系统 200全部展开时, 也可以使轮式布料机械以另一种工作状 态进行施工作业; 此时, 可以使主行驶系统 100与地面接触 (或通过适当 的辅助支腿机构与地面接触), 仅使二臂 220、 三臂 230、 四臂 240和五臂 250展开, 通过改变二臂 220、 三臂 230、 四臂 240和五臂 250的位置, 能 够在预定的范围内进行布料。
根据上述描述,布料机架 400不限于包括回转机构,在保证根端臂 210 与布料机架 400相连的情况下, 也可以实现本发明的目的。 另外, 为了使 两个驱动支腿机构 601上的车桥总成的行驶方向保持平行, 也可以所述驱 动支腿机构 601的延伸方向之间保持平行; 此时, 驱动支腿机构 601内端 可以与布料机架 400固定相连, 也可以通过其他方式保持相连。
当然, 根据实际需要, 可以对相关部件进行相应布置, 比如: 也可以 使泵送系统 320与布料机架 400或臂架系统 200通过现有的其他方式相连; 在行 3史状态,可以使泵送系统 320的至少部分重量作用在驱动支腿机构 601 上, 进而省去泵机辅助行驶系统 310; 支腿机构 600不限于上述布置, 在 保持至少三个支腿机构 600 的前提下, 也可以省去向后延伸的支腿机构 600; 主行驶系统 100不限于安装在两个支腿机构 600上,可以安装在至少 一个支腿机构 600,形成至少一个驱动支腿机构 601 ,就可以实现本发明的 目的。 如: 可以使车架安装在第一个支腿机构 600的悬臂上; 此时, 可以 使第二个支腿机构 600通过竖向铰接轴与布料机架 400相连;在工作状态, 可以使第二支腿机构 600相对于第一个支腿机构绕该竖向铰接轴摆动适当 的角度; 在从工作状态转换到行驶状态时, 可以使第二个支腿机构 600向 第一个支腿机构 600摆动适当的角度, 与第一个支腿机构 600并拢, 使第 二个支腿机构 600支撑在车架上; 进而,在行驶状态,可以使臂架系统 200 支承在两个支腿机构 600的悬臂上方, 以有利于保持收拢后臂架系统 200 的稳定。 另外, 在行 3史状态下, 收拢后的臂架系统 200不限于支撑在两个 驱动支腿机构 601上, 只要收拢后的臂架系统 200至少一部分重量作用在 至少一个所述驱动支腿机构 601上, 就可以实现本发明的目的 (当然, 根 据实际需要, 可以通过上述的机架辅助行驶系统 420承受臂架系统 200的 部分重量)。
为了便于轮式布料机械进行状态转换, 该轮式布料机械还可以设置检 测系统, 检测系统可以包括状态检测传感器和控制器; 状态检测传感器用 于检测根端臂 210的状态; 控制器根据状态检测传感器的检测信号输出位 置信号, 进而使操作人员可以根据控制器输出的位置信号确定根端臂 210 的状态。 状态检测传感器可以直接检测根端臂 210的重心高度, 也可以通 过检测主行驶系统 100是否与工作面 (路面 )接触, 确定根端臂 210的状 态, 也可以通过检测根端臂 210与布料机架 400之间的位置关系确定根端 臂 210的状态。 本例中, 状态检测传感器为倾角传感器, 通过该倾角传感 器检测根端臂 210的倾斜角; 控制器根据倾角传感器的检测结果确定根端 臂 210是否与工作面垂直, 或是否与工作面平行; 进而判断是否完成状态 转换, 在判断完成状态转换时, 发送预定位置信号。 可以在轮式布料机械 从相应的工作状态转换到行驶状态时, 控制器发送一种位置信号, 在轮式 布料机械从行驶状态转换到相应的工作状态时, 使控制器发送另一种位置 信号; 进而根据位置信号的不同, 操作人员可以确定状态转换是否完成。
为了保证轮式布料机械的工作稳定性, 还包括在相关部分设置的配重 块, 比如可以设置与布料机架和 /或支腿机构相连的配重块, 以平衡整机受 力。
请参考图 2至图 4, 本发明实施例一提供的轮式布料机械还包括位于 所述臂架系统 200的根端臂 210外端的操作室 800; 操作室 800内可以包 括行驶控制机构和泵送控制机构, 通过行驶控制机构可以控制主行驶系统 100的运转, 通过泵送控制机构能够控制泵送系统 320的运转。 这样, 在 行驶状态, 操作人员可以在操作室 800内控制主行驶系统 100的运转, 方 便轮式布料机械的转场; 在相应的工作状态, 操作人员可以在操作室 800 内控制泵送系统 320的运转。 当然, 操作室 800还可以位于臂架系统 200 的根端臂 210或臂架系统 200的其他臂杆上。
为了方便轮式布料机械, 减小对其他辅助机械设备的依赖性, 还可以 单独设置翻转驱动机构。 比如: 轮式布料机械还可以包括设置一端与臂架 系统 200的相应臂杆相连的翻转油缸; 在轮式布料机械从行驶状态转换到 相应的工作状态时, 使翻转油缸的另一端支撑在地面, 使翻转油缸伸长, 就可以驱动臂架系统 200翻转。 在行马史状态下, 布料机架的回转中心线不 与水平面垂直时, 也可以使翻转油缸与布料机架 400相连, 即通过布料机 架 400与臂架系统 200相连; 在轮式布料机械从行驶状态转换到相应的工 作状态时, 使翻转油缸一端支撑在地面, 再使其伸长, 就可以驱动布料机 架 400进行翻转,或者驱动臂架系统 200和布料机架 400—同翻转。 当然, 翻转驱动机构不限于通过翻转油缸实现, 也可以通过其他现有的其他机构 实现, 如杠杆机构、 滑轮机构, 等等。
为了保证泵送总成 300与布料机架 400之间的位置,方便泵送系统 320 泵送口与臂架系统 200的输送管道之间连接, 还可以使泵送总成 300与布 料机架 400之间形成适当的连接机构。 请参考图 5 , 该图是本发明实施例 二提供的轮式布料机械, 该图示出了该轮式布料机械处于行驶状态的结构 示意图。
与实施例一提供的轮式布料机械相比,实施例二提供轮式布料机械中, 泵机辅助行驶系统 310包括泵送支架 311和与泵送支架 311相连的车桥总 成。 泵送支架 311与布料机架 400通过中间铰接轴 301铰接相连, 中间铰 接轴 301与水平面垂直(在布料机架 400包括回转机构时, 泵送支架 311 具体与固定部件 402相连)。这样, 泵送系统 320与布料机架 400之间的相 对位置就可以通过中间铰接轴 301确定, 进而能够为泵送系统 320的泵送 口与臂架系统 200的输送管道之间连接提供方便,提高物料输送的稳定性。 可以理解, 此时, 泵送系统 320的重量通过铰接连接部分地传递到布料机 架 400上, 泵送系统 320的部分重量作用在泵机辅助行驶系统 310上; 这 样有利于合理分配轮式布料机械的负载分布。 当然, 在其他情况下, 也可 以通过相应的结构, 使泵送系统 320的部分重量传递到其他部分。
为了保证泵送系统 320的工作稳定性, 本实施例中, 还设置有与泵送 支架 311铰接相连的支腿机构 600 (为了区别起见, 该支腿机构 600标记 为 603 )。 支腿机构 603的内端与所述泵送支架 311通过支腿铰接轴铰接相 连, 该支腿铰接轴的轴线与中间铰接轴 301的轴线平行。 在相应的工作状 态, 支腿机构 603的外端支撑在工作面上, 可以为泵送支架 311提供支撑 力, 进而可以提高泵送系统 320的稳定性。
上述技术方案中包括的技术内容, 可以根据实际需要进行结合, 以形 成相应的技术方案, 解决实际遇到的相应技术问题, 满足实际需要。 施例的说明只是用于帮助理解本发明提供的技术方案。 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; 比如: 由于布料机架 400承载较大, 可以根 据实际需要设置内端与布料机架 400相连的支腿机构 600; 操作室 800不 限于设置在向上伸出的支腿机构 600上, 也可以根据实际控制需要, 设置 在相应支腿机构 600的外端, 或支腿机构 600的其他部分; 这些改进和修 饰也落入本发明权利要求的保护范围内。
