Description
支脚盘及包含该支脚盘的工程机械 技术领域 本发明属于工程机械辅助支撑领域, 具体而言, 涉及一种支脚盘及包含该支脚盘 的工程机械。 背景技术 现有大吨位、 超大吨位轮式起重机因吊载较重, 支腿的支反力很大, 支腿的支脚 盘需要承受大载荷, 以满足接地比压的要求, 因而结构尺寸设计较大, 重量也随之增 大。 而如何使支脚盘快速就位就成了急需解决的问题。 现有国内外超大吨位起重机的 支脚盘基本是采用人工和辅助吊车移位对正, 因而效率低, 劳动强度大。 现有的支脚盘在定位时,当垂直油缸向下即将接触到支脚盘的垂直缸球头支座时, 因初始摆放支脚盘不可能非常精确地使垂直缸球头与支脚盘球座中心对齐, 致使支脚 盘球座受到水平和竖直两个方向的载荷。 传统的支脚盘受到这两个载荷后, 支脚盘底 平面与垫板发生克服面面摩擦的滑移, 但当面面摩擦力大于支脚盘所受到的水平方向 载荷后, 支脚盘停止移动, 而此时支脚盘与垂直油缸之间并未安装到位, 这样就使得 支脚盘与垫板之间存在内部水平方向载荷。 当起重机回转时, 会产生回转力矩, 增大 此内部水平方向载荷, 进而导致发生支脚盘滑移。 此时支脚盘滑移则容易造成整个起 重机的晃动, 因而非常危险。 发明内容 本发明旨在提供一种支脚盘及包含该支脚盘的工程机械, 结构简单, 能够使支脚 盘快速准确定位, 提高工程机械工作过程中的安全性。 为了实现上述目的, 根据本发明的一个方面, 提供了一种支脚盘, 包括支脚盘主 体以及设置在支脚盘主体的底板上的弹性可回缩的弹性滚动支承装置, 弹性滚动支承 装置具有缩入支脚盘主体内的缩回位置。 进一步地, 弹性滚动支承装置包括: 安装座, 安装座固定设置在底板上, 安装座 的顶部固定设置有止挡件; 滚动支承座, 上下可滑动地设置在安装座内, 滚动支承座 的底部设置有滚动体; 弹性机构, 弹性机构设置在止挡件和滚动支承座之间。
进一步地, 安装座还包括固定设置在底板上的套筒, 套筒上沿轴向方向开设有滑 槽, 滚动支承座上设置有与滑槽配合的凸块, 止挡件可拆卸地设置在安装座的顶部。 进一步地, 弹性机构为弹簧, 弹簧的一端固定连接在止挡件上, 弹簧的另一端固 定连接在滚动支承座上。 进一步地, 支脚盘主体的底板上设置有开口, 底板上对应开口的位置固定设置有 安装座, 安装座竖直向上延伸, 并形成滑动空间, 安装座的顶部设置有止挡件, 弹性 滚动支承装置可滑动地设置在安装座内。 进一步地, 弹性滚动支承装置包括滚动支承座和弹性机构, 滚动支承座可滑动地 设置在安装座内, 滚动支承座的底部固定设置有滚动体, 弹性机构设置在止挡件和滚 动支承座之间。 进一步地, 安装座包括两块相对设置的安装板, 两个安装板分别设置在开口的两 相对侧, 止挡件可拆卸地连接在两个安装板之间, 安装板上沿竖直方向设置有滑槽, 滚动支承座的两侧对应设置有与滑槽配合的凸块。 进一步地, 滚动体为万向轮。 进一步地, 支脚盘主体的顶部设置有多个吊耳。 根据本发明的另一方面, 提供了一种工程机械, 包括支脚盘, 该支脚盘为上述的 支脚盘。 应用本发明的技术方案, 支脚盘包括支脚盘主体以及设置在支脚盘主体的底板上 的弹性可回缩的弹性滚动支承装置, 弹性滚动支承装置可缩入支脚盘主体内。 在进行 垂直油缸的安装时, 如果支脚盘受力较小, 弹性滚动支承装置会根据垂直油缸的施力 情况 (水平方向载荷) 移动, 由于弹性滚动支承装置与支撑面之间为滚动摩擦, 因此 摩擦力较小, 使得弹性滚动支承装置对垂直油缸的水平方向载荷的反应更加快速, 从 而对支脚盘快速定位, 使其到达与垂直油缸配合的合适位置。 当垂直油缸施加压力过 大, 超过弹性滚动支承装置所能承受的压力时, 弹性滚动支承装置就会缩入支脚盘主 体内, 使得支脚盘主体承受垂直油缸的压力, 此时经过之前的调整, 能够有效保证垂 直油缸与支脚盘之间安装到位, 消除垂直油缸与支脚盘之间的水平载荷, 保证工程机 械的安全操作。
附图说明 构成本发明的一部分的附图用来提供对本发明的进一步理解, 本发明的示意性实 施例及其说明用于解释本发明, 并不构成对本发明的不当限定。 在附图中: 图 1示出了根据本发明的实施例的支脚盘的结构示意图; 图 2示出了根据图 1的实施例的支脚盘的俯视结构示意图; 图 3 输出了根据本发明的实施例的支脚盘的弹性滚动支承装置的剖视结构示意 图; 以及 图 4示出了根据本发明的实施例的支脚盘与垂直油缸配合时的结构示意图。 具体实施方式 下文中将参考附图并结合实施例来详细说明本发明。 需要说明的是, 在不冲突的 情况下, 本申请中的实施例及实施例中的特征可以相互组合。 如图 1和图 2所示,根据本发明的实施例, 一种支脚盘包括支脚盘主体 10以及设 置在支脚盘主体 10的底板 11上的弹性可回缩的弹性滚动支承装置 20, 弹性滚动支承 装置 20具有缩回支脚盘主体 10内的缩回位置, 可在外力的作用下通过弹性收缩作用 缩入支脚盘主体 10内。 在支脚盘的顶部设置有弧形凹槽 14, 可以与垂直油缸 30的连 接端相配合, 使支脚盘与垂直油缸 30之间实现定位支撑。 结合参见图 4所示,在进行垂直油缸 30的安装时, 由于支脚盘在竖直方向上受力 较小, 弹性滚动支承装置 20的弹性作用将支脚盘本体撑离支撑面,支脚盘主要靠弹性 滚动支承装置 20实现位置的移动。 而在垂直油缸 30与支脚盘的安装初始阶段, 由于 初始位置摆放的不准确性, 垂直油缸 30的中心与支脚盘的中心存在偏差,支脚盘会受 到竖直方向和水平方向两个方向的压力。 弹性滚动支承装置 20会根据垂直油缸 30的 施力情况移动,由于弹性滚动支承装置 20与支撑面之间为滚动摩擦,因此摩擦力较小, 使得弹性滚动支承装置 20对垂直油缸 30的水平方向载荷的反应更加灵敏快速, 能够 快速调整支脚盘与垂直油缸 30的相对位置关系,减小或者消除支脚盘所受到的水平方 向的载荷, 从而使支脚盘可以快速定位, 使其到达与垂直油缸 30配合的合适位置, 也 即垂直油缸 30的球头正好落入弧形凹槽 14内。当垂直油缸 30施加压力过大,超过弹 性滚动支承装置 20所能承受的压力时, 弹性滚动支承装置 20就会缩入支脚盘主体 10 内, 使得支脚盘主体 10承受垂直油缸 30的压力, 此时经过之前的调整, 能够有效保
证垂直油缸 30与支脚盘之间安装到位, 消除垂直油缸 30与支脚盘之间的水平载荷, 保证工程机械的安全操作。 结合参见图 3所示,在一个优选的实施例当中, 弹性滚动支承装置 20包括安装座 21、 滚动支承座 22和弹性机构 24, 在底板 11上设置有开口 12, 弹性滚动支承装置 20对应该开口 12设置。 其中安装座 21固定设置在底板 11上, 安装座 21的顶部固定 设置有止挡件 211。 安装座 21还包括固定设置在底板 11上的套筒。 滚动支承座 22上 下可滑动地设置在安装座 21的套筒内, 且在滚动支承座 22的底部设置有滚动体 23, 优选地, 滚动体 23为滚轮, 更有选地, 滚轮为万向轮, 万向轮可以保证弹性滚动支承 装置 20的位置调整更加灵活快速。 优选地, 止挡件 211可拆卸地设置在安装座 21的 套筒的顶部。 止挡件 211例如为挡板, 滚动体 23例如为滚轮。 支脚盘还可以在套筒上沿轴向方向开设滑槽 212, 滚动支承座 22上设置有与滑槽 212配合的凸块 221, 滚动支承座 22通过凸块 221沿套筒上的滑槽 212滑动, 从而对 滚动支承座 22形成导向作用。 此种结构下, 滑槽 212延伸至套筒的顶端, 在安装时, 首先将滚动支承座 22安装在套筒内后, 再将止挡件 211固定连接在安装座 21的套筒 的顶部。 弹性机构 24设置在止挡件 211和滚动支承座 22之间, 在正常状态下, 弹性机构 24将滚动支承座 22的滚动体 23顶出支脚盘本体的底板 11夕卜, 从而使支脚盘本体通 过弹性滚动支承机构来进行支撑, 当支脚盘所受到的垂直方向的压力过大并超过弹性 机构 24的弹性作用力时, 弹性滚动支承装置 20则缩回支脚盘主体 10内,整个支脚盘 通过支脚盘底板 11进行支撑。 优选地, 弹性机构 24为弹簧, 弹簧的一端固定连接在 止挡件 211上, 弹簧的另一端固定连接在滚动支承座 22上。 该弹性机构 24还可以为 其它的具有弹性回复功能的弹性结构, 例如橡胶等。 在另一个优选的实施例当中, 支脚盘主体 10的底板 11上设置有开口 12, 底板 11 上对应开口 12的位置固定设置有安装座 21, 安装座 21竖直向上延伸, 并形成滑动空 间, 安装座 21的顶部设置有止挡件 211, 弹性滚动支承装置 20可滑动地设置在安装 座 21内。 弹性滚动支承装置 20包括滚动支承座 22和弹性机构 24, 滚动支承座 22可滑动 地设置在安装座 21 内, 滚动支承座 22的底部固定设置有滚动体 23, 弹性机构 24设 置在止挡件 211和滚动支承座 22之间。
安装座 21包括两块相对设置的安装板, 两个安装板分别设置在开口 12的两相对 侧,止挡件 211可拆卸地连接在两个安装板之间,安装板上沿竖直方向设置有滑槽 212, 滚动支承座 22的两侧对应设置有与滑槽 212配合的凸块 221。 安装座 21还可以为其它的结构, 例如安装座 21可以包括套筒, 止挡件 211可拆 卸地设置在套筒的顶部, 在套筒上沿长度方向可以设置滑槽 212, 弹性滚动支承装置 20沿该滑槽 212可滑动地设置在安装座 21上。 在支脚盘主体 10上还可以设置多个吊耳 13, 以便于对支脚盘进行转运或者位置 调整。 根据本发明的实施例, 一种工程机械包括支脚盘, 该支脚盘为上述任一种支脚盘。 从以上的描述中, 可以看出, 本发明上述的实施例实现了如下技术效果: 支脚盘 包括支脚盘主体以及设置在支脚盘主体的底板上的弹性滚动支承装置, 弹性滚动支承 装置可缩入支脚盘主体内。 在进行垂直油缸的安装时, 如果支脚盘受力较小, 弹性滚 动支承装置会根据垂直油缸的施力情况 (水平方向载荷) 移动, 由于弹性滚动支承装 置与支撑面之间为滚动摩擦, 因此摩擦力较小, 使得弹性滚动支承装置对垂直油缸的 水平方向载荷的反应更加快速, 从而对支脚盘快速定位, 使其到达与垂直油缸配合的 合适位置。 当垂直油缸施加压力过大, 超过弹性滚动支承装置所能承受的压力时, 弹 性滚动支承装置就会所如支脚盘主体内, 使得支脚盘主体承受垂直油缸的压力, 此时 经过之前的调整, 能够有效保证垂直油缸与支脚盘之间安装到位, 消除垂直油缸与支 脚盘之间的水平载荷, 保证工程机械的安全操作。 以上仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本领域的技术人 员来说, 本发明可以有各种更改和变化。 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。
