Description

混凝土泵送单元的安装结构和混凝土泵送设备
技术领域
本发明涉及混凝土输送领域, 具体地, 涉及一种混凝土泵送单元的安 装结构和包括该混凝土泵送单元的安装结构的混凝土泵送设备。 背景技术
通常情况下, 混凝土泵送单元的作业参数需要适应于其所应用的工况。 然而, 在实际作业过程中, 工况不是一成不变的, 而是会受到各种因素的 影响从而产生变化。 如果工况的变化仍然处于混凝土泵送单元的适用范围 之内, 则该混凝土泵送单元仍然适用; 但是, 如果工况的变化已经超出混 凝土泵送单元的适用范围, 则会影响工程作业的质量。
具体来说, 如果待泵送的混凝土的粘性过大 (例如需要泵送高强度混 凝土时), 则混凝土泵送单元难以很好地完成混凝土的泵送作业。 或者, 如 果工况要求混凝土泵送单元具有较高的泵送效率, 除非更换更大功率的混 凝土泵送单元之外, 相对小功率的混凝土泵送单元面对该工况时勉为其难。
例如, 在预制管桩的浇筑作业工程中, 如果先将管桩模具的上下模事 先合好, 然后利用混凝土泵, 通过混凝土输送管道将混凝土输送入已合好 的管桩模型腔中, 可实现预制管桩的自动化生产。 然而, 由于 PHC管桩采 用了 (如 C80) 高强混凝土, 该高强混凝土的粘性较大且流动性较差, 因 此对现有的混凝土泵送单元的泵送效率提出较高的要求。
因此, 如何使混凝土泵送单元获得较高的泵送效率成为本领域需要解 决的技术问题。 发明内容
本发明的目的是提供一种混凝土泵送单元的安装结构, 利用该混凝土 泵送单元的安装结构能够使该混凝土泵送单元获得相对较高的泵送效率。 本发明的另一目的提供一种包括该混凝土泵送单元的安装结构的混凝土泵 送设备。
为了实现上述目的, 本发明提供一种混凝土泵送单元的安装结构, 该 混凝土泵送单元包括: 一对液压缸、 与该对液压缸连接的一对砼缸以及位 于所述一对砼缸的出料端的料斗, 所述安装结构包括用于安装所述混凝土 泵送单元的机架, 所述混凝土泵送单元的设置方式为从所述一对液压缸到 所述一对砼缸的出料端逐渐升高。
优选地, 所述一对砼缸的中心轴线所形成的平面 M与所述机架的纵向 方向 S之间的夹角 α为 2度至 45度。
优选地, 所述一对砼缸的中心轴线所形成的平面 Μ与所述机架的纵向 方向 S之间的夹角 α为 5度至 20度。
优选地, 该安装结构还包括角度调节机构, 所述混凝土泵送单元通过 该角度调节机构安装在所述机架上, 以能够调节所述一对砼缸的中心轴线 所形成的平面 M与所述机架的纵向方向 S之间的夹角 α 。
优选地, 所述角度调节机构包括铰接销轴和限位装置, 所述一对砼缸 的出料端通过所述铰接销轴铰接于所述机架, 所述限位装置连接在所述混 凝土泵送单元与机架之间, 以限定所述混凝土泵送单元与机架的相对位置。
优选地, 所述限位装置包括铰接于所述机架的调节缸, 该调节缸具有 活塞杆, 该活塞杆的端部铰接于所述混凝土泵送单元。
优选地, 该混凝土泵送单元包括位于所述一对液压缸和所述一对砼缸 之间的水箱; 所述限位装置包括固定于所述机架上的安装板, 所述混凝土 泵送单元穿过所述安装板延伸并且所述水箱位于与所述安装板相邻的位 置, 所述安装板具有沿高度方向设置的多个安装位置, 所述混凝土泵送单 元的水箱可选择地固定安装于所述安装板的多个安装位置中的一个。
优选地, 所述安装板所在的平面 N与所述一对砼缸的中心轴线所形成 的平面 M之间的夹角 β为 65度到 85度。
优选地, 所述安装板为弹性板。
优选地, 在所述安装板与所述混凝土泵送单元的水箱之间设置有缓冲 衬垫。
本发明还提供了一种混凝土泵送设备, 该混凝土输送泵车包括本发明 所提供的上述混凝土泵送单元的安装结构。
对于混凝土粘性过大的工况, 为了提高混凝土泵送单元的泵送效率, 本发明的发明人进行了大量的理论研究和现场试验, 在此基础上本发明的 发明人发现: 在混凝土粘性过大的工况中, 之所以混凝土泵送单元的泵送 效率受到限制, 其根本原因在于混凝土泵送单元在进行泵送过程中, 由于 混凝土的粘性较大导致混凝土不能充分地进入砼缸。 换句话说, 混凝土进 入砼缸的吸入效率受到其较大粘性的不利影响。
传统上, 混凝土泵送单元的设置方式为水平设置方式或所谓的 "正斜 置"方式。
水平设置方式为混凝土泵送单元的纵向方向与水平方向平行的设置方 式。 对于这种设置方式的混凝土泵送单元来说, 当混凝土进入对应的砼缸 时, 主要是利用砼缸的吸力而被吸入砼缸中。
所谓的 "正斜置"方式为混凝土泵送单元的设置有料斗的端部位于相 对较低的位置而相对的另一端部位于相对较高的位置的设置方式。 对于这 种设置方式的混凝土泵送单元来说, 当混凝土进入对应的砼缸时, 需要使 砼缸的吸力克服部分的混凝土的重力而被吸入砼缸中。
正是基于上述发现, 本发明的发明人主要针对混凝土泵送单元的设置 方式提出了本发明的技术方案以及优选的各种方式。
根据本发明的技术方案, 由于所述混凝土泵送单元在机架上的设置方 式为: 从所述一对液压缸到所述一对砼缸的出料端逐渐升高, 因此当料斗 中的混凝土物料从料斗进入对应的砼缸时, 既会受到该砼缸的吸力的作用, 还能够利用上述设置方式而带来的自身重力的势能, 从而更为有利于混凝 土进入对应的砼缸中, 进而提高了混凝土进入砼缸时的吸入效率, 实现本 发明的目的。 显然, 本发明的技术方案在提高所述吸入效率方面比上述水 平设置方式和 "正斜置"方式具有较大的优势。
本发明的其他特征和优点将在随后的具体实施方式部分予以详细说 明。 附图说明
附图是用来提供对本发明的进一步理解, 并且构成说明书的一部分, 与下面的具体实施方式一起用于解释本发明, 但并不构成对本发明的限制。 在附图中:
图 1 是根据本发明优选实施方式的混凝土泵送单元的安装结构的示意 图;
图 2是图 1中 I区域的局部放大示意图;
图 3是表示水箱与机架连接关系的示意图。 具体实施方式
以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是, 此处所描述的具体实施方式仅用于说明和解释本发明, 并不用于限制本发 明。
如图 1所示, 本发明所提供了一种混凝土泵送单元的安装结构, 其中, 混凝土泵送单元包括: 一对液压缸 100、与该对液压缸 100连接的一对砼缸 200以及位于所述一对砼缸 200的出料端的料斗 300, 所述安装结构包括用 于安装所述混凝土泵送单元的机架 400, 其中, 所述混凝土泵送单元的设置 方式为从所述一对液压缸 100到所述一对砼缸 200的出料端逐渐升高。 这 里的 "高"是以 (混凝土输送泵车的) 混凝土泵送单元在工作状态时相对 于地面的方位来说的。
混凝土泵送单元可以为普遍采用的液压活塞式双缸混凝土泵。 该种液 压活塞式双缸混凝土泵的结构形式以及工作原理可以参考《工程机械》(李 启月主编, 中南大学出版社, 2009年 10月第 1版第 5次印刷)第 9章中关 于混凝土输送泵的描述。
在本发明的技术方案中, 主要是对混凝土泵送单元的布置方式和 /或安 装结构进行了改进, 因此将简略或省略对混凝土泵送单元本身的描述, 而 是着重描述与混凝土泵送单元的布置方式和 /或安装结构关系密切的技术特 征。
机架 400为混凝土泵送单元提供安装基础。机架 400可以有多种形式。 例如机架 400可以为固定在地面上的基座; 还可以是具有行走轮的基座; 还可以设置在车辆上。
利用本发明的技术方案, 由于所述混凝土泵送单元在机架上的设置方 式为: 从所述一对液压缸到所述一对砼缸的出料端逐渐升高, 因此当料斗 中的混凝土物料从料斗进入对应的砼缸时, 既会受到该砼缸的吸力的作用, 还能够利用上述设置方式而带来的自身重力的势能, 从而更有利于混凝土 进入对应的砼缸中, 进而提高了混凝土进入砼缸时的吸入效率。
通常, 一对液压缸分别与一对砼缸同轴设置, 因此, 一个液压缸与对 应的一个砼缸具有相同的中心轴线, 另一液压缸与另一砼缸具有相同的中 心轴线, 该两条中心轴线彼此平行。 因而, 一对砼缸 200 的中心轴线形成 一个平面 M, 如图 1所示。
由于本发明的混凝土泵送单元的设置方式, 如图 1 所示, 所述一对砼 缸 200的中心轴线所形成的平面 M与所述机架 400的纵向方向 S (通常, 在完成安装的状态下, 机架 400的纵向方向 S与水平方向为平行的) 之间 的夹角 α为 2度至 45度, 以适应于不同的工况要求以及混凝土泵送单元自 身的工作参数的适应性。
进一步优选地, 所述一对砼缸 200的中心轴线所形成的平面 Μ与所述 机架 400的纵向方向 S之间的夹角 α为 5度至 20度。
如上所述, 混凝土泵送单元安装在机架 400上, 并具有上述设置方式。 混凝土泵送单元相对于机架 400的相对位置关系可以是保持固定不变的 (例 如, 混凝土泵送单元可以通过螺栓连接的方式固定连接于所述机架, 从而 使上述夹角 α为固定不变的)。 但优选地, 为了针对不同的工况要求, 从而 使得混凝土泵送单元相对于机架 400具有相适应的相对位置关系, 混凝土 泵送单元的安装结构还包括角度调节机构, 所述混凝土泵送单元通过该角 度调节机构安装在所述机架 400上, 以能够调节所述一对砼缸 200的中心 轴线所形成的平面 Μ与所述机架 400的纵向方向 S之间的夹角 α, 从而适 应于不同的工况要求。 具体来说, 上述夹角 α越大, 则吸入效率提高得越 角度调节机构可以具有多种形式, 例如可以将混凝土泵送单元设置在 可相对于机架 400转动的基座上, 或者混凝土泵送单元直接与机架 400铰 接连接。
为了更准确地确保混凝土泵送单元相对于机架 400 的相对位置, 优选 地, 所述角度调节机构包括铰接销轴 401 (如图 2所示)和限位装置, 所述 一对砼缸 200的出料端通过所述铰接销轴 401铰接于所述机架 400,所述限 位装置连接在所述混凝土泵送单元与机架 400之间, 以限定所述混凝土泵 送单元与机架 400的相对位置。
所述混凝土泵送单元在其一对砼缸 200的出料端通过铰接销轴 401铰 接于机架 400, 因而整个混凝土泵送单元能够围绕铰接销轴 401转动, 从而 使混凝土泵送单元相对于机架 400调整位置, 进而调整上述角度 α。 限位 装置则连接在机架 400与混凝土泵送单元之间, 以限定 (和保持) 混凝土 泵送单元与机架 400 的相对位置, 使混凝土泵送单元在工作过程中保持稳 定。
因此, 针对具体的工况, 可以先使混凝土泵送单元相对于机架 400进 行旋转, 达到预定的相对位置时 (即上述角度 α达到预定值时), 再利用限 位装置将混凝土泵送单元限定于该相对位置, 然后进行泵送作业。
限位装置可以具有多种形式。 例如, 限位装置可以包括设置在机架上 的多个固定环和设置在混凝土泵送单元上的连接钩, 根据混凝土泵送单元 相对于机架 400 的不同位置, 可以将连接钩挂在多个固定环中的对应的固 定环上, 从而起到限位作用。
再如, 所述限位装置可以包括铰接于所述机架 400 的调节缸, 该调节 缸具有活塞杆, 该活塞杆的端部铰接于所述混凝土泵送单元。 所述调节缸 可以为液压缸或气缸。
还如, 如图 1和图 3所示, 该混凝土泵送单元包括位于所述一对液压 缸 100和所述一对砼缸 200之间的水箱 500;所述限位装置包括固定于所述 机架 400上的安装板 402,所述混凝土泵送单元穿过所述安装板 402延伸并 且所述水箱 500位于与所述安装板 402相邻的位置, 所述安装板 402具有 沿高度方向设置的多个安装位置 (即该多个安装位置分别位于不同的高度 水平上), 所述混凝土泵送单元的水箱 500可选择地固定安装于所述安装板 402的多个安装位置中的一个。
通过将水箱 500固定安装于安装板 402上的多个安装位置中不同的安 装位置, 能够使混凝土泵送单元相对于机架 400具有不同的相对位置。 安 装板 402与水箱 500之间可以通过多种方式安装, 如通过螺栓、 销钉连接 等方式。
当混凝土泵送单元进行作业时, 噪声和振动都相对较大, 因而为了减 少混凝土泵送单元的振动冲击, 从而降低噪声并保护混凝土泵送单元, 尤 其是缓冲沿混凝土泵送单元纵向方向上往复运动的冲击, 优选地, 所述安 装板 402所在的平面 N与所述一对砼缸 200的中心轴线所形成的平面 M之 间的夹角 β为 65度到 85度, 如图 1所示。
通过将安装板 402所在的平面 Ν与所述一对砼缸 200的中心轴线所形 成的平面 Μ之间的夹角 β设计为 65度到 85度, 从而使上述安装板 402能 够适应于混凝土泵送单元在机架 400上的安装方位的要求, 同时也能够抵 抗混凝土泵送单元在泵送时沿纵向方向往复运动所产生的振动和 /或冲击 (例如, 安装板 402可以利用自身的挠性而随混凝土泵送单元的泵送作业 而动作 (如颤动), 从而起到缓冲或抵抗上述振动和 /或冲击)。
进一步优选地, 所述安装板 402所在的平面 Ν与所述一对砼缸 200的 中心轴线所形成的平面 Μ之间的夹角 β为 70度到 80度。
优选地, 为了使安装板 402具有较好的挠性, 安装板 402的厚度相对 较薄, 从而使安装板 402便于实现缓冲作用。
此外, 为了更好地实现缓冲作用, 所述安装板 402可以优选为弹性板。 例如, 安装板 402可以由具有弹性的材料制成, 如安装板 402可以为橡胶 板或其他具有弹性的塑料板。 当然, 安装板 402在具有缓冲冲击的功能的 同时, 也需要能够承载混凝土泵送单元作用在安装板 402上的载荷的结构 强度。 针对安装板 402 的具体结构和材料选择, 本领域技术人员可以根据 具体的工况而加以设计选择。
此外, 优选地, 在所述安装板 402与所述混凝土泵送单元的水箱 500 之间设置有缓冲衬垫, 也同样能够起到缓冲冲击的作用。 缓冲衬垫可以为 橡胶垫或塑料垫等。
以上详细描述了本发明所提供的混凝土泵送单元的安装结构的技术特 征。 此外, 本发明还提供了一种混凝土泵送设备, 该混凝土泵送设备包括 本发明所提供的上述混凝土泵送单元的安装结构。
例如, 所述混凝土泵送设备可以为固定式混凝土泵 (机架 400为固定 的)、 车载式混凝土泵 (机架 400固定安装在泵车的车架上, 或者直接利用 泵车的车架作为上述安装结构的机架 400) 或混凝土输送泵车。 以上结合附图详细描述了本发明的优选实施方式, 但是, 本发明并不 限于上述实施方式中的具体细节, 在本发明的技术构思范围内, 可以对本 发明的技术方案进行多种简单变型, 这些简单变型均属于本发明的保护范 围。
另外需要说明的是, 在上述具体实施方式中所描述的各个具体技术特 征, 在不矛盾的情况下, 可以通过任何合适的方式进行组合, 而不限于权 利要求书中各项权利要求的引用关系。 为了避免不必要的重复, 本发明对 各种可能的组合方式不再另行说明。
此外, 本发明的各种不同的实施方式之间也可以进行任意组合, 只要 其不违背本发明的思想, 其同样应当视为本发明所公开的内容。
