一种移动式混凝土搅拌站及其配料机 本申请要求于 2010 年 05 月 31 日提交中国专利局、 申请号为 201010193094.0、 发明名称为"一种移动式混凝土搅拌站及其配料机,,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
本发明涉及混凝土制备机械, 特别是涉及一种移动式混凝土搅拌站的 配料机, 还涉及包括该配料机的移动式混凝土搅拌站。
背景技术
混凝土搅拌站是用来制备混凝土的联合装置。 因其具有机械化和自动 化程度高、 制备效率高等特点而广泛应用于混凝土工程量大、施工周期长、 施工集中的公路路面、 桥梁工程、 大中型水利电力工程、 建筑施工以及混 凝土制品工厂中。 根据是否可以转场运输, 混凝土搅拌站可以分为固定式 混凝土搅拌站和移动式混凝土搅拌站。 由于移动式混凝土搅拌站可以根据 施工场地的位置进行转场运输, 能够满足工程建设的多样化需求, 具有很 强的适应性能, 因此得到了广泛应用。
移动式混凝土搅拌站一般包括配料机和搅拌机。 配料机用于存储和计 量碎石、 砂子、 水泥等骨料, 并将经计量的骨料供给到搅拌机。 搅拌机用 于搅拌水和预定配料比的骨料形成混凝土, 然后向外供给。 运输设备可以 将混凝土运输到预定地点进行混凝土施工。
移动式混凝土搅拌站的配料机主要包括配料机主体和输送机。 根据配 料机主体和输送机之间的关系, 配料机有两种具体结构: 一种是分体式结 构的配料机。 这种配合料包括配料机主体和输送机; 配料机主体和输送机 分别通过支腿安装在不同的基础上。 配料机主体包括储料箱, 计量装置; 储料箱用于存储预定量的骨料, 计量装置用于在称量预定骨料后, 将预定 量的骨料投送到输送机的计量斗中。 输送机用于将投送于计量斗中的骨料 向外输送。 另一种是整体式结构的配料机。 这种配料机的配料机主体和输 送机为一个整体, 配料机主体通过支腿安装在预定的基础上, 输送机悬挂 在配料机主体下方。 配料机用于存储骨料, 皮带输送机用于对骨料进行计 量, 并在计量后将预定量的骨料直接或间接输送到搅拌机。
为了满足工程施工的需要, 保证移动式混凝土搅拌站制备混凝土的效 率, 配料机一般要具有较大容积的储料箱、 较大计量能力的计量装置和输 送机, 以向搅拌机输送骨料。 为了满足这些要求, 当前配料机主体和输送 机均具有较大的外形轮廓尺寸; 因此, 在配料机转场运输时, 分体式结构 和整体式结构的配料机均需要先将配料机主体和输送机分离, 再分别将配 料机主体和输送机运输到预定的地点; 到达预定地点后, 再将配料机主体 和输送机安装在一起。 上述转场运输操作不仅具有运输过程复杂、 转场运 输周期长等不足, 还使得配料机的转场运输成本非常高。
因此。 如何在满足移动式混凝土搅拌站工作需要的同时, 提高配料机 的转场运输性能, 成为是当前本领域技术人员面临的一个技术难题。
发明内容
针对上述技术难题, 本发明的第一个目的在于, 提供一种状态可变的 移动式混凝土搅拌站的配料机, 使其在工作状态下的具有较大的外形轮 廓, 在运输状态下具有较小的外形轮廓, 进而在满足移动式混凝土搅拌站 工作需要的同时, 提高配料机的转场运输性能。
在提供上述配料机的基础上, 本发明的第二个目的在于, 提供一种包 括上述配料机的移动式混凝土搅拌站, 以使移动式混凝土搅拌站具有良好 的转场运输性能。
为了实现上述第一个目的, 本发明提供的移动式混凝土搅拌站的配料 机包括配料机主体、 输送机和多个支腿; 所述配料机主体通过支腿支撑在 预定的基础上, 与现有技术的区别在于, 所述配料机具有工作状态和运输 状态, 在所述工作状态和运输状态, 所述输送机均通过悬挂部件悬挂于配 料机主体下方; 所述支腿包括顺序相连的至少两节节臂, 并能够通过改变 节臂之间的位置改变该支腿的垂向高度。
可选的, 所述支腿包括套接在一起的至少两节节臂。
可选的, 所述支腿还包括用于驱动支腿在伸展状态和收缩状态之间转 换的伸缩油缸。
可选的, 所述支腿包括至少在垂向方向上叠加的两节节臂。

可选的, 配料机还包括位于输送机与配料机主体之间的计量斗, 所述 计量斗包括下斗体和与下斗体通过可拆卸机构相连的上斗体, 所述下斗体 与输送机固定, 所述上斗体前端垂向高度小于其后端垂向高度。
优选的, 在运输状态, 所述配料机整体的外形轮廓尺寸不大于 11.8m X 2.13m X 2.18m或 11.8m x 2.13m x 2.72m或 13.58m x 2.34m x 2.71m或 12.01m x 2.33m x 2.15m或 12.05m x 2.12m x 1.96m。
为了实现上述第二个目的, 本发明提供的移动式混凝土搅拌站包括配 料机和搅拌机, 与现有技术的区别在于, 所述配料机为上述任一种移动式 混凝土搅拌站的配料机。
与现有的配料机相比, 本发明提供的配料机具有两种状态, 既工作状 态和运输状态, 在所述工作状态和运输状态, 所述输送机均通过悬挂部件 悬挂于配料机主体下方; 所述支腿包括顺序相连的至少两节节臂, 在从所 述工作状态转换到运输状态时, 所述支腿能够通过改变节臂之间的位置改 变该支腿的垂向高度, 使支腿的垂向高度减少, 进而使配料机的外形轮廓 减小。 由于配料机在运输状态的外形轮廓小于其在工作状态下的外形轮 廓。 在转场运输之前, 不需要将配料机主体和输送机分离; 在运输时, 不 需要分别运输; 在安装时, 也不需要再通过吊装将配料机主体和输送机安 装在一起; 因此, 本发明提供的配料机具有更好的转场运输性能。 同时, 在工作状态下, 由于支腿具有较大的垂向高度, 配料机也具有较大的外形 轮廓尺寸, 使得配料机能够储存较大量的骨料, 进而能够以比较高的速度 计量骨料和输送骨料, 满足移动式混凝土搅拌站制备混凝土的需要。
在进一步的技术方案中, 支腿包括套接在一起的至少两节节臂, 形成 伸缩式支腿, 该技术方案利用伸缩结构可以方便地实现支腿状态的转换, 进一步地改变配料机的外形轮廓, 实现本发明的目的。 优选的, 通过伸缩 油缸驱动支腿进行状态转换, 可以提高转场运输的自动操作性。
在进一步的技术方案中, 支腿包括至少在垂向方向上叠加两节节臂, 在从所述工作状态转换到运输状态时, 能够通过减少支撑在配料机主体和 预定基础之间节臂的数量减小支腿的垂向高度。 这样一方面可以提高支腿 的支撑能力, 保证工作状态下配料机的工作可靠性; 另一方面, 可以使支 腿状态变化与移动式混凝土搅拌站比较恶劣的工作场景相适应, 满足状态 变换的需要。 进一步的, 节臂之间通过横向铰接轴铰接相连, 可以方便支 腿状态转换, 进一步地提高配料机的转场运输性能。
在进一步的技术方案中, 储料箱的挡板与配料机主体进行可拆卸机构 或铰接轴相连; 在从工作状态转换到运输状态时, 通过改变挡板与配料机 主体之间的位置关系减小配料机的总高度; 这样可以满足工作状态储存骨 料的需要; 同时, 可以很方便地使配料机状态的转换, 使运输状态下的配 料机具有较小的外形轮廓。
在进一步的技术方案中, 所述输送机通过可拆卸的悬挂部件悬挂于配 料机主体下方, 在从所述工作状态转换到运输状态时, 可以通过更换或调 整悬挂部件与输送机或 /配料机主体之间的连接点调整输送机的高度, 使输 送机的最低点与配料机主体的下支架之间的垂向距离减小; 该技术方案能 够避免由于输送机而使配料机的外形轮廓增大, 进而为进一步减小运输状 态下配料机的外形轮廓提供良好前提。
在进一步的技术方案中, 在所述工作状态, 所述计量斗通过可拆卸机 构与输送机上表面相连; 这样, 在需要进行状态转换时, 可以将计量斗拆 下, 为输送机向上运动提供足够空间; 同样, 在计量斗包括与输送机固定 要进行状态转换时, 也能够通过将上斗体拆下为输送机向上运动提供相应 的空间。
在优选的技术方案中, 所述配料机整体的外形轮廓具有预定的、 与集 装箱内容积相匹配的规格。 在运输转场时, 该技术方案提供的配料机可以 整体地装入预定规格的集装箱内, 再通过适当的运输工具进行转场运输, 这样能够更进一步地提高配料机的转场运输性能, 还有利于远距离转场运 输。

具体实施方式
下面结合附图对本发明进行详细描述, 本部分的描述仅是示范性和解 释性, 不应对本发明的保护范围有任何的限制作用。
请参考图 1 , 图 1为本发明提供配料机在工作状态下的侧面结构示意 图。 所述工作状态为移动式混凝土搅拌站在预定位置制备混凝土时, 配料 机向搅拌机供给骨料时的状态。
配料机包括配料机主体 100、 储料箱 200、 支腿 300和输送机 400。 配 料机主体 100具有上支架 110和下支架 120。
储料箱 200为储存骨料提供预定的空间。 在工作状态下, 储料箱 200 至少部分位于上支架 110上方, 其上方部分包括多个挡板 210, 每个挡板 210均向上伸展, 相邻的挡板 210之间相互配合, 在上支架 110上方围成 预定的空间, 使储料箱 200能够储存预定量的骨料。 本例中, 每个挡板 210 下侧边分别通过适当的可拆卸的铰接轴与上支架 110铰接。
在工作状态下, 支腿 300上端与配料机主体 100的下支架 120相连, 下端支撑在预定的基础上, 工作状态下的基础称为工作基础 510。 请参考 图 2, 该图为图 1中 I-I部分放大图。 为了使配料机能够从工作状态向运输 状态转换, 本例中, 支腿包括上节臂 301和下节臂 302; 在工作状态, 上 节臂 301上端与配料机主体 100固定, 上节臂 301下端与下节臂 302上端 配合, 下节臂 302支撑在工作基础 510上。 为了方便配料机状态的转换, 上节臂 301和下节臂 302之间通过横向铰接轴 303铰接相连在上节臂 301 上还设置有卡板 304, 在下节臂 302向上旋转后, 可以将下节臂 302通过 紧固件固定在卡板 304上。 为了提高支腿 300的整体强度, 在配料机两侧 还分别设置支腿横梁 310, 每个支腿横梁 310将一侧的四个支腿 300的上 节臂 301连接起来。
请参考图 3和图 4 , 图 3是图 1中的 A向视图, 图 4是在图 1的基础 上, 去掉挡板和前侧的支腿后形成的视图; 该图的目的是为了清楚地显示 输送机与配料机主体之间的连接结构。
输送机 400通过适当的悬挂部件悬挂在配料机主体 100下方, 悬挂部 件有多种选择; 本例中, 输送机 400通过四个拉板 121分别吊装在四个称 重组件 122上, 四个称重组件 122分别套在四个称重传感器 123 , 四个称 重传感器 123通过紧固件分别固定在配料机主体 100的下支架 120的四个 角上, 前端和后端两个, 左右两侧的拉板 121、 称重组件 122和称重传感 器 123对称分布。
本例中,输送机 400前端与下支架 120之间的垂向距离小于输送机 400 后端与下支架 120之间的垂向距离, 这样就使输送机 400前端向上抬起, 使输送机 400具有预定的倾斜角; 所述倾斜角为输送机 400的前端与后端 形成的倾斜面与水平面形成的角度。 设置倾斜角的意义在于: 提高输送机 前端的高度, 进而减小配料机前端出料位置与提升机接料位置之间的高度 差, 降低移动式混凝土搅拌站基础建设的成本, 方便移动式混凝土搅拌站 运行。 优选的技术方案是, 使输送机 400的倾斜角可调, 以根据实际情况 调节配料机的出料位置的高度。 本例中, 四个拉板 121相同, 可以互换, 且每个拉板 121两端分别与输送机 400和称重组件 122铰接, 以减 d、输送 机 400前后摇摆时产生的计量误差, 提高骨料计量的准确性; 同时, 为了 方便调节输送机 400的倾斜角, 拉板 121下部可以设置有多个铰接孔, 输 送机 400前端与后端分别与拉板 121不同位置的铰接孔铰接, 可以调节输 送机 400前端向上抬起的高度, 获得预定的倾斜角。 同时, 选择拉板 121 预定位置的铰接孔与输送机 400铰接相连, 还可以调节输送机 400的前端 和 /或后端的高度, 适应配料机工作场景的需要。 可以理解, 也可以在拉板 121 上部设置垂向布置的多个铰接孔, 选择不同的铰接孔与称重组件 122 铰接, 也可以实现调整输送机 400高度及其倾斜角的目的。
称重传感器 123优选压式称重传感器, 相对于拉式称重传感器而言, 压力传感器具有更高的可靠性。
请参考图 5 , 该图是图 3中 Π-Π部分放大图。 为了防止输送机 400在 工作状态下左右晃动幅度过大, 在拉板 121与邻近的支腿 300之间还设置 有横向延伸的拉紧装置 124; 优选的, 拉紧装置 124可以为普通弹簧、 空 气弹簧、 弹性材料等制作的柔性结构, 以使其具有预定伸缩性能, 实现拉 板 121与邻近支腿 300之间的柔性连接; 在输送机 400左右晃动时, 具有 伸缩性能的拉紧装置可以緩冲输送机 400晃动对支腿 300及拉板 121的冲 击。
请参考图 6, 该图是图 4中 ΠΙ-ΠΙ部分放大图, 图中用双点划线示出 支腿横梁。 本例中, 为了防止输送机 400前后晃动, 在配料机的四个角位 置还设置拉杆组件 125 , 拉杆组件 125两端分别与输送机 400和支腿横梁 310相连, 在前后方向上使输送机 400与支腿 300相对固定。 优选的技术 方案是, 使拉杆组件 125两端分别与输送机 400和支腿横梁 310铰接, 以 适应输送机 400位置的变化; 与拉板 121相同, 进一步地, 也可以使拉杆 组件 125具有预定的伸缩性 以适应输送机 400高度调整及倾斜角调整时, 输送机 400的位置变化。
可以理解, 还可以在拉板 121与配料机主体 100之间、 拉杆组件 125 与配料机主体 100之间、 在输送机 400与支腿 300之间及在其他固定的机 构设备与输送机 400之间设置适当的连接结构, 以防止输送机 400晃动幅 度过大, 保持输送机 400的稳定。
参考图 1和图 4, 本例中, 输送机 400上方还设有计量斗 410, 计量斗 410包括下斗体 411和上斗体 412 下斗体 411固定在输送机 400的上表面, 上斗体 412下端面可拆卸地安装在下斗体 411下端面, 优选的, 使上斗体 412包括可拆分的多个部分, 以方便上斗体 412的拆卸。 本例中, 由于输 送机 400具有倾斜角, 下斗体 411的下端面与上端面保持平行, 为了使计 量斗 410上端面与储料箱 200的出料口相对应, 上斗体 412为倾斜结构。 请参考图 7 , 该图是图 1所示配料机中, 计量斗的上斗体的立体结构示意 图。 上斗体 412前端垂向高度小于其后端垂向高度, 形成一个前端低, 后 端高的倾斜结构, 且上斗体 412下端面与上端面所在平面之间的夹角与输 送机 400的倾斜角相对应, 并相互补充。 在工作状态下, 倾斜结构的上斗 体 412使计量斗 410上端面保持与水平面平行, 并使计量斗 410的上端面 与储料箱 200的出料口相对应, 不仅使配料机的结构更加紧凑, 还能够保 证从储料箱 200流出的骨料顺利地进入计量斗 410中。
请参考图 8和图 9, 图 8是本发明提供的配料机在运输状态下的侧面 结构示意图, 图 9是在图 8的基础上去掉防护网和支腿下节臂后的侧面结 构示意图。 所述运输状态为转场运输时配料机所处的状态。
在运输状态下, 配料机依赖于支腿 300支撑于预定的基础上, 在运输 状态, 该预定基础称为运输基础 520。 结合图 1和图 8, 在工作状态下, 配 料机的总体高度为 H, 在运输状态下, 配料机的总体高度为 h, 本例中, h=H/2。 在从工作状态转换到运输状态时, 配料机的总体高度减小为原来的 一半, 使得该配料机在运输状态的外形轮廓远小于其在工作状态下的外形 轮廓。 这样, 在进行转场操作时, 可以方便地将配料机主体 100和输送机 400 —起运输, 提高配料机转场运输的方便性。 同时, 在工作状态, 配料 机也具有较大的外形轮廓尺寸, 使得配料机能够储存较大量的骨料, 以比 较高的速度计量骨料和输送骨料, 满足搅拌机搅拌、 制备混凝土的需要。
为了实现减小配料机外形轮廓的目的, 在从工作状态转换到运输状态 时, 对本实施例提供的配料机进行了如下操作:
第一、 使每个支腿的下节臂 302相对于上节臂 301绕横向铰接轴 303 向上旋转, 从而使支腿 300上节臂 301的下端支撑在运输基础 520上, 下 节臂 302到达图 8所示的位置, 并用卡板 304使下节臂 302保持固定, 进 而使支腿 300最上端和最小端之间的垂向距离减小, 减小配料机的总体高 度。
第二、 将输送机 400向上提升, 使输送机 400的最低点与配料机主体 100的下支架 120之间的垂向距离减小。 本例中, 为了使输送机 400能够 向上提升, 首先通过拆卸上斗体 412与下斗体 411之间的可拆卸连接, 将 上斗体 412与下斗体 411分离, 使输送机 400的下斗体 411与配料机主体 100之间具有预定的空间。 然后, 再使输送机 400连同下斗体 411一同上 升, 在上升到预定位置后, 将输送机 400用预定的悬挂部件悬挂在配料机 主体 100下方, 以进行转场运输, 本例中, 将拉杆组件 125作为运输状态 下的悬挂部件。 具体过程是: 将拉板 121和拉紧装置 124拆下, 将拉杆组 件 125与支腿横梁 310连接一端拆开, 并将该端与配料机主体 100的下支 架 120相连。 请参考图 10, 该图是图 9中 IV-IV部分放大图。 在运输状态, 输送机 400依靠位于四个角上的拉杆组件 125悬挂在配料机主体 100的下 支架 120下方; 由于拉杆组件 125短于拉板 121 , 从而使输送机整体向上 升高了预定的距离; 同时, 由于四个拉杆 125长度相等, 在运输状态, 输 送机 400前端和后端基本保持在一个平面内,输送机 400前端与下支架 120 之间的垂向距离不小于输送机 400后端与下支架 120之间的垂向距离。
可以理解, 还可以将计量斗 400做成整体结构, 在工作状态下, 将计 量斗 400通过可拆卸机构安装在输送机 400上表面; 在从工作状态转换为 运输状态时, 可以将计量斗 410从输送机 400上整体拆下。 在计量斗 410 不影响输送机 400上升时, 也可以直接使输送机 400上升预定的距离, 以 减小配料机运输状态下的总体高度。 在运输状态下, 也可以拉板 121作为 悬挂部件悬挂输送机 400, 此时, 可以在拉板 121上选择适当的铰接孔或 其他连接孔, 并使其两端分别与配料机主体 100和输送机 400相连, 以实 现提升输送机 400高度的目的。
第三、 将储料箱 200的挡板 210分别从配料机主体 100上拆下或向下 翻转, 使挡板 210不再占用配料机主体 100上支架 110上方的空间, 减小 储料箱 200对运输状态下配料机的总体高度的影响。 如图 8和 9所示, 在 将挡板 210拆下时, 配料机主体 100的上支架 110上端形成配料机轮廓的 最上端, 从而大大减小了运输状态配料机的总体高度。
正是釆用上述多项措施, 使配料机运输状态下的总体高度远小于其工 作状态下的总体高度, 使其外形轮廓尺寸大幅度减小, 为转场运输提供便 利; 由于运输时, 输送机 400通过拉杆组件 125悬挂于配料机主体 100下 方, 并不需要将配料机主体 100和输送机 400分别运输, 还可以方便配料 机的安装和调试。 可以理解, 根据配料机实际情况, 可以选择上述的一种 措施和多种措施实现上述减小配料机外形轮廓的目的。 优选的, 还可以根 据集装箱的规格, 使运输状态下配料机具有预定的外形轮廓尺寸, 以能够 在运输状态下, 将其放入预定的集装箱内运输。 比如: 在运输状态, 可以 使配料机的外形轮廓尺寸不大于 11.8m 2.13m 2.18m, 11.8m 2.13m 2.72m 13.58m 2.34m 2.71m、 12.01m 2.33m 2.15m或 12.05m 2.12m 1.96m, 等等。
根据上述描述, 本领域技术人员还可以使支腿 300包括更多节节臂, 并使各节臂之间通过预定的横向铰接轴铰接相连, 这样可以使配料机在工 作状态具有更大的尺寸, 以满足混凝土制备需要; 在从工作状态转换到运 输状态时, 通过旋转至少一节节臂, 就可以减小支腿 300在垂向方向上高 度。 在支腿 300具有更多节节臂时, 还可以根据实际需要, 使预定数量的 节臂支撑配料机主体 100, 以获得不同的预定高度, 满足实际工作的需要。 当然, 也可以使节臂之间直接叠加; 优选的, 还可以在相邻的节臂之间设 置相配合的结构, 比如说: 可以在一节节臂上端设置定位凸起, 在与其相 邻的上方节臂的下端设置与定位凸起配合的定位^^ 这样, 在实际应用中, 可以以根据状态的需要, 使预定数量的节臂相配合, 支撑配料机主体 100 , 使配料机主体 100与预定基础之间具有预定的距离。 另外, 还可以使支腿 300 包括套接在一起的至少两节节臂, 形成可沿垂向方向伸缩的伸缩式支 腿; 在从所述工作状态转换到运输状态时, 使该支腿从伸展状态转换到缩 回状态; 还可以设置驱动支腿在伸展状态和收缩状态之间转换的伸缩油 缸, 以方便支腿的伸展和回缩。 为了保证支腿 100的可靠性, 还可以在相 邻的节臂之间设置相配合的锁止销和锁止孔, 或其他锁止机构, 以在预定 的状态下, 使支腿保持预定的垂向高度。 根据上述描述, 本领域技术人员 还可以设置其他具体的结构, 使支腿能够通过改变节臂之间的位置关系改 变支腿本身的垂向高度。
在提供上述配料机的基础上, 本发明还提供了一种包括上述配料机的 移动式混凝土搅拌站, 由于配料机能够在满足移动式混凝土搅拌站工作需 要的同时, 提高配料机的转场运输性能, 具有该配料机的移动式混凝土搅 拌站也具有制备效率高, 转场运输方便的技术效果。
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, 比如说: 拉板与拉杆组件不限于上述具体结构, 也可以是其他能 够实现悬挂输送机的悬挂部件, 拉板与称重组件、 拉板与输送机之间, 可 以为销轴连接, 也可以是心轴连接, 这些改进和润饰也应视为本发明的保 护范围。
