本发明要解决的技术问题在于， 针对现有技术的不足， 提供一种钢包滑动水口装 置， 滑块与支架的相对运动过程中， 其压力的波动性明显降低， 提高了系统的整体稳 定性。
本发明所解决的上述问题， 是通过如下技术方案实现的：
一种钢包滑动水口装置， 包括固定在钢包上的安装板， 该安装板上固设有底座， 底座的顶端与滑动水口驱动机构相连， 该底座上设有支架， 支架上设有用于产生压力 的弹性元件， 支架上设有滑块， 在底座与滑块的相对表面上开设凹槽， 凹槽内分别嵌 设上、 下滑板砖， 所述的支架上设有滚动机构， 滑块上对应设置导向机构， 滑块上对 应设置的导向机构相对于支架上设置的滚动机构往复运动， 以控制钢包滑动水口的打 开或关闭。 . 滚动机构可以为对称设置在支架上的滚轮， 导向机构可以为设置于滑块边缘的导 轨。 在支架一端内侧和滑块一端外侧对应设置定位枢接部， 使滑块以其为转轴按照一 定的方式绕支架转动而不会自行脱离。 定位枢接部为设置在支架一端内侧的弧形凹槽 和对应设置在滑块一端外侧的凸柱， 或设置在支架一端内侧的凸柱和对应设置在滑块 一端外侧的弧形凹槽， 该凸柱嵌设在弧形凹槽中。 该弧形凹槽为侧壁开设有开口的套 筒形状， 该开口的宽度与滑块底部外侧设置的凸柱的直径大小相应， 装配时将凸柱沿 弧形凹槽的开口嵌入。 弹性元件为内置有弹簧组的弹簧盒， 该弹簧盒的上、 下两端通 过彼此连接的两根横梁构成一框架， 该框架铰接在底座上。
综上所述， 本发明将滚动机构对称设置在支架上， 导向机构对应设置在滑块上， 在滑块与支架的相对运动过程中， 其压力的波动性明显降低， 提高了系统的整体稳定 性。
下面结合附图和具体实施例对本发明的技术方案进行详细地说明。 附图说明

实施例一
如图 1所示， 为本发明实施例一的整体结构示意图之一。 从图 1中可知， 本发明 提供了一种钢包滑动水口装置， 该装置包括固定在钢包上的安装板 1上， 该安装板 1 上固设有底座 2， 底座 2的一端与滑动水口驱动机构 3相连， 该底座 2上设有支架 4， 支架 4上设有用于产生压力的弹性元件， 支架 4上还枢设有滑块 5， 在底座 2与滑块 5 的相对表面上开设凹槽 21、 凹槽 51 (图中未示出）， 凹槽 21和凹槽 51内分别嵌设上 滑板砖 22、 下滑板砖 52, 支架 4上设有滚动机构， 滑块 5上对应设置导向机构， 滑块 上对应设置的导向机构相对于支架上设置的滚动机构往复运动， 以控制钢包滑动水口 的打开或关闭。 滚动机构为设置在支架上的滚轮 41。 如图 2所示， 为本发明滚动机构 半轴滚轮的局部结构示意图。从图 2中可知， 所述的滚轮 41可以根据需要设置成半轴 滚轮， 半轴 42的结构如图 2所示， 滚轮 41穿设在半轴 42上并可以半轴 42为轴转动， 半轴 42固定在支架 4上。 如图 3所示， 为本发明滑块的结构示意图之一。 从图 3中可 知， 导向机构为设置于滑块 5边缘的导轨 51， 该导轨 51 固定在滑块 5上。 由于该导 轨 51为易损部件， 采用与滑块 5的分体设置， 便于导轨 51的更换。 如图 4所示， 为本发明实施例一的整体结构示意图之二。 从图 4中可知， 支架 4 一端底部内侧和滑块 5—端底部外侧对应设置定位枢接部， 使滑块 5以其为转轴绕支 架 4转动， 以便于滑块 5在安装到支架 4过程中的定位。 图 5为本发明滑块的结构示 意图之二。 图 4结合图 5可知， 定位枢接部为设置在支架一端底部内侧的弧形凹槽 44 和对应设置在滑块一端底部外侧的凸柱 52， 该凸柱 52嵌设在弧形凹槽 44中。 弧形凹 槽 44为侧壁开设有开口的套筒形状， 该开口 441 (如图 1中所示） 的宽度与滑块底部 外侧设置的凸柱 52的直径大小相应，装配时将凸柱 52延弧形凹槽 44的开口 441嵌入 即可。 从图 1中可知， 弹性元件为弹簧组 6， 支架 4上开设有容置空间 45 , 用于容纳 该弹簧组 6。 结合图 3可知， 支架 4底部内侧和滑块 5底部外侧对应设置定位枢接部， 还可以为设置在支架底部内侧的凸块 （图中未示出） 和对应设置在滑块底部外侧凹槽 53， 该凸柱嵌设在凹槽 53中。
如图 1所示， 底座 2的顶端设有滑动水口驱动机构托座 31， 滑动水口驱动机构 3 套设在该托座 31内驱动滑块 5运动。 支架 4外部还设有用于隔热的外护板 7。
本实施例中所提供的钢包滑动水口装置， 其安装过程是这样的：'先将底座 2固定 在钢包的安装板 1上， 在底座 2顶端固定滑动水口驱动机构托座 31， 将带有外护板 7 的支架 4固定在底座 2上，将弹簧组 6置入支架 4内的容置空间 45 ,并将该空间封闭。 将滑块 5上的凸柱 52嵌入支架 4上的弧形凹槽 44内， 向下翻转滑块 5， 将驱动机构 3 装入托座 31并固定。 安装座砖 8和上水口 9， 置入上滑板砖 22、 下滑板砖 52， 将驱 动机构 3与滑块 5头部的槽 （图中未示出） 连接， 顶紧机构与上滑板砖 22、 下滑板砖 52内部连接并向上翻转滑块 5， 使其在支架 4内与底座 2扣合。 安装下水口 10， 且下 水口 10应在驱动机构 3收缩前安装好。 驱动机构 3收缩， 将滑块 5从支架 4拉起， 此 时弹性元件建立压力。 关闭外护板 7并将其锁定， 即完成整体装置的安装。 实施例二
如图 6所示， 为本发明实施例二的整体结构示意图。 从图 6中可知， 本实施例与 实施例一的区别在于弹性元件的结构有所不同， 本实施例中的弹性元件为内置有弹簧 组的弹簧盒 100， 该弹簧盒 100的上、 下两端通过彼此连接的两根横梁 101、 102构成 一框架 103 , 该框架 103铰接在底座 2上。
在本实施例中， 弹簧盒 100自身的安装可以是， 弹簧拉杆 104通过弹簧盒 100低 部的孔穿过弹簧盒 100， 长槽 （图中未示出） 内放入弹簧组 105后， 压板 106通过自 身上的孔与弹簧拉杆 104装配， 并通过螺母与弹簧拉杆的作用将压板 106压紧。 本实施例的其他技术特征与实施例一相同， 详细内容请参阅上文所述， 在此不再 赘述。
上述两种实施例的内部结构尽管存在差异， 但其浇注的工作过程是相同的， 都是 在驱动机构 3的作用下，滚动机构在导向机构上运动以控制上水口 9和下水口 10的错 开和对正， 实现钢包滑动水口的打开或关闭， 来控制浇注过程中的流量和浇注动作。 最后所应说明的是： 以上实施例仅用以说明本发明而非限制， 尽管参照较佳实施 例对本发明进行了详细说明， 本领域的普通技术人员应当理解， 可以对本发明进行修 改或者等同替换， 而不脱离本发明的精神和范围， 其均应涵盖在本发明的权利要求范 围当中。
