一种混凝土布料杆 本申请要求于 2012 年 9 月 18 日提交中国专利局、 申请号为 201220477087.8、 发明名称为 "一种混凝土布料杆" 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
本发明涉及混凝土泵送技术领域, 尤其涉及一种混凝土布料杆。 背景技术
混凝土布料杆是一种常见的混凝土布料设备, 小型移动式布料杆因其 结构筒单、 可移动等特点, 应用越来越广泛。 如图 1和图 2所示, 小型移 动式布料杆一般包括底座 3a、 设于底座上的布料臂 1、 布料管 2, 底座下方 设有支腿 32a和支腿座 33a。 在布料时, 支腿 32a通过支腿座 33a支撑在施 工场地上, 以确保布料臂 1 离开施工场地的地面一定高度, 方便布料臂 1 和布料管 2的转动, 进而将混凝土料输送至需要的地方。 通过支腿的作用, 一方面可以确保布料臂 1和布料管 2离地一定高度; 另一方面, 支腿可以 确保混凝土布料杆具有一定的支撑面积, 保证了整个混凝土布料杆的工作 稳定性。
根据图 1可以看出来, 已有的小型移动式布料杆中, 布料管 2末端的 离地高度只能通过调节末节布料管 21的倾斜角度来调整, 其调整的范围偏 小, 导致其适用场地受到限制, 严重影响其适应能力。 比如, 在布料点高 度不一的施工场地上, 布料管 2 的末端无法够到某些高度的布料点, 这给 正常施工带来不利影响。 另一方面, 这种混凝土布料杆的布料臂 1 的离地 高度是不能调节的, 在某些具有障碍物的施工场地上, 布料臂 1 的离地高 度不够时, 其无法越过障碍物, 会导致布料管 2 的末端无法顺利转动到布 料点上, 最终影响顺利施工。

所述可伸缩支腿 32包括: 用于限定所述第一支腿臂 321与所述第二支 腿臂 322相对位置的插销、 以及开设于所述第一支腿臂 321和第二支腿臂 322上的通孔 6。 其中, 所述通孔 6沿可伸缩支腿 32的长度方向设置, 所 述插销插接于所述通孔 6。 也就是说, 所述插销插接于所述通孔 6, 且所述 插销和所述通孔 6具有沿可伸缩支腿 32长度方向设置的配合位置。
例如: 为方便第一支腿臂 321与第二支腿臂 322的定位, 在这两个支 腿臂上设置通孔 6, 可以是在第一支腿臂 321上设置多个通孔 6, 而在第二 支腿臂 322上只设置一个通孔 6,也可以是在第一支腿臂 321上设置一个通 孔 6,而在第二支腿臂 322上只设置多个通孔 6,还可以是在第一支腿臂 321 和第二支腿臂 322上均设置多个通孔 6, 这里, 本实施例对此不作限定。 其 中, 所述多个通孔 6可沿第一支腿臂 321、 和 /或第二支腿臂 322的长度方 向设置。 当所述第一支腿臂 321相对于所述第二支腿臂 322伸缩到合适的 或需要的位置时, 利用插销插入第一支腿臂 321和第二支腿臂 322相对应 的通孔 6, 以限定第一支腿臂 321与第二支腿臂 322的相对位置,从而实现 通过调节二者相对位置来实现调节可伸缩支腿 32的长度。 当然,在实践中, 某些部位的通孔 6也可以用槽来代替, 本实施例对此不作限定。
本实施例中, 通过设置插销和通孔的方式来限定第一支腿臂与第二支 腿臂的相对位置, 以便使支腿能够在确定的长度下稳定工作。 并且, 通过 设置多个沿支腿臂长度方向的配合位置, 使得支腿具有多个明确的长度, 方便施工时选取适宜的长度, 这样做的优点在于支腿结构筒单、 成本低、 可靠性好。
2 )伸缩调节方式二
与上述销轴、 通孔的调节方式可替换的是, 在一优选实施例中, 可采 用伸缩油缸实现上述可伸缩支腿 32的长度调节。 因此, 所述可伸缩支腿 32 可包括用于驱动所述第二支腿臂 322相对所述第一支腿臂 321伸缩的伸缩 油缸, 所述伸缩油缸一端连接于所述第一支腿臂 321 , 另一端连接于所述第 二支腿臂 322。 例如: 所述第一支腿臂 321与第二支腿臂 322的伸缩可以通过在支腿 臂内设置伸缩油缸来实现, 比如将伸缩油缸的缸筒固定设置于第一支腿臂 321内, 将伸缩油缸的活塞杆固接至第二支腿臂 322。
3 )伸缩调节方式三
当然, 另一优选实施例中, 还可以通过齿轮齿条机构来实现两个支腿 臂之间的伸缩, 所述可伸缩支腿 32包括用于驱动所述第二支腿臂 322相对 所述第一支腿臂 321伸缩的齿轮齿条机构, 所述齿轮齿条机构包括: 设于 所述第一支腿臂 321和所述第二支腿臂 322两者之一上的齿轮、 及设于另 一者上的齿条、 以及用于控制所述齿轮、 所述齿条的驱动电机和控制器件。
例如, 在一实施例中, 可将齿轮及齿轮驱动机构设置于第一支腿臂 321 上, 将齿条设置于第二支腿臂 322的适当位置, 这样, 第二支腿臂 322即 可相对第一支腿臂 321运动。
在上述技术方案中, 通过第一支腿臂和第二支腿臂的可伸缩结构使得 整个支腿的长度可以根据需要进行调节, 通过支腿长度的调节可以实现底 架离地高度的调节, 进而实现布料臂和布料管离地高度的可调, 因此, 在 施工场地存在障碍物或者不同高度的布料点时, 该混凝土布料杆可以通过 增加支腿长度的方式来进行调整, 避免或降低布料臂和布料管离地高度不 够给施工所带来的不便, 有效增强其适应能力。
需要指出的是, 除了上述各实施例所述的自动伸缩调节方式外, 第一 支腿臂 321和第二支腿臂 322之间的相对运动还可以通过人工手动推拉来 实现。
例如, 通过调节所述可伸缩支腿 32与所述底架 31之间的夹角大小, 实现对混凝土布料杆的布料臂 1或布料管 2离地高度的调节。 这里, 可结 合上述各实施例中的所述可伸缩支腿 32的伸缩调节方式, 对所述可伸缩支 腿 32与所述底架 31的夹角调节方式进行说明: 在一优选实施例中, 所述混凝土布料杆还包括: 设置于所述底架 31上 的连杆座 4。 所述第一支腿臂 321通过辅助连杆 5与所述连杆座 4铰接; 或 者, 所述第一支腿臂 321通过液压油缸与所述连杆座 4连接。 其中, 所述 连杆座 4上设有一个以上的铰接孔 7,所述辅助连杆 5通过所述铰接孔 7与 所述连杆座 4铰接。
例如, 在进一步的技术方案中, 该混凝土布料杆可以包括辅助连杆 5 和连杆座 4, 第一支腿臂 321与底架 31铰接, 连杆座 4固定于底架 31上, 连杆的两端分别与第一支腿臂 321、 连杆座 4铰接。 这样的话, 可以方便布 料杆的拆卸和装运。还可以在连杆座上设置多个铰接孔 7, 这些铰接孔 7呈 "一" 字排列, 且沿着所述第一支腿臂 321与所述底架 31的铰接点至所述 底架 31中心的方向设置。
需要说明的是, 本实施例可与前述各实施例结合使用, 当然, 本领域 技术人员应当理解的是, 本实施例也可以单独实现对混凝土布料杆的布料 臂 1或布料管 2离地高度的调节。 例如: 当混凝土布料杆需要调整布料臂 1 或布料管 2的离地高度时, 将辅助连杆 5铰接于适当的铰接孔 7上。 如此, 便能够实现对混凝土布料杆的布料臂 1或布料管 2离地高度的调节。
本实施例中, 通过在连杆座上设置多个铰接孔, 使得辅助连杆的铰接 位置可以根据需要进行改变, 进而调整支腿的倾斜角度, 这样可以更大范 围的调整底架和布料臂的离地高度
上述各实施例中, 所述布料管 2包括末节布料管 21 , 所述末节布料管 21在竖直平面和 /或水平面内可转动。 在本实施例中, 通过设置可灵活转动 的末节布料管, 使得布料管的末端可以方便的移动到各布料点上。
因此, 本发明通过调节可伸缩支腿结构, 使得整个支腿的长度能够根 据需要进行调节, 进而调节布料臂和布料管的离地高度, 能够避免或降低 布料管和布料臂离地高度不够所带来的不便, 有效增强其适应能力。 以上所述仅为本发明的优选实施例而已, 凡在本发明的精神和原则之 内, 所作的任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围 之内。
工业实用性
本发明提供的混凝土布料杆通过设置长度可调的支腿, 使得混凝土布 料杆的布料管和布料臂离地高度可以根据施工场地进行调整, 提升了混凝 土布料杆的适应能力, 为稳定的、 顺利的完成作业提供了极大便利。 因此, 本发明具有工业实用性。
