具体实鮮式
下面结合附图和具体实施例对本发明作进一步详细描述， 但不作 为对本发明的限定。
图 1为本发明的高炉炉顶溜槽布料器的整体结构示意图； 图 2为 本发明的高炉炉顶溜槽布料器的另一个方向的整体结构示意图； 图 3 为图 2的俯视图； 图 4为本发明的高炉炉顶溜槽布料器的万向框架与 下回转支承内圈、 溜槽托架的连接结构示意图； 如图 1至图 4所示， 本发明的高炉炉顶溜槽布料器， 包括气密箱体 1、 顶盖 2、 喉管 3、 旋 转套筒 4、 上回转支承 5、 下回转支承 6、 溜槽 7、 万向框架 8、 平动托 圈 9、 溜槽水平传动装置 10和三个油缸 11。 顶盖 2中部具有容许喉管 3穿过的通孔 （图中未示出）， 顶盖 2盖在气密箱体 1的上端， 顶盖 2 的外缘的大法兰与气密箱体 1 固定连接。 在本发明中， 上回转支承 5 和下回转支承 6均采用常用的结构， gp， 均包括可相对旋转但不可相 对上下移动的内圈和外圈。 顶盖 2内缘的小法兰与上回转支承 5的内 圈固定连接。 喉管 3穿过顶盖 2的通孔设置在气密箱体 1内。
如图 1、 图 2和图 4所示， 旋转套筒 4位于气密箱体 1内， 并且旋 转套筒 4的上部套设在喉管 3外， 旋转套筒 4的上端与上回转支承 5 的外圈固定连接， 而且上回转支承 5的内圈与顶盖 2固定连接， 因此 旋转套筒 4与顶盖 2在竖直方向上成相互静止状态。 上回转支承 5的 外圈的旋转由设置在顶盖 2上的溜槽水平传动装置 10驱动， 并带动旋 转套筒 4一起绕顶盖 2的中心线作 360度的旋转。 旋转套筒 4内设置 有可随其一起旋转的溜槽 7， 旋转套筒 4与溜槽 7的连接关系具体为： 旋转套筒 4的筒壁上开设有两个直径上对置的耳轴孔 （图中未示出）， 每个耳轴孔内均设置有耳轴套 13，耳轴套 13内分别安装有能在耳轴套 13内旋转的耳轴 12。溜槽 7的外侧固定连接有溜槽托架 71， 溜槽托架 71的上部两端通过花键分别连接耳轴 12的一端，从而使溜槽 7挂在两 个耳轴 12上， 耳轴 12的穿过耳轴套 13， 也就是溜槽 7通过耳轴挂在 了旋转套筒 4上。 溜槽托架 71与溜槽 7始终处于相对静止状态， 并随 旋转套筒 4一起旋转。
继续结合图 1至图 3， 三个油缸 11相对于溜槽 7的水平旋转中心 线轴向均布于顶盖 2上， 三个油缸 11分别通过过渡连杆 15与平动托 圈 9连接， 带动平动托圈 9上下运动。 平动托圈 9套设于旋转套筒 4 外， 平动托圈 9的内缘的下部与下回转支承 6的外圈采用螺栓固定连 接成一体， 因此平动托圈 9可带动下回转支承 6的外圈和内圈上下运 动。 平动托圈 9的外缘设置导轮 91， 气密箱体 1的内壁上设置与导轮 91对应的导轨 16， 导轮 91设置在导轨 16上并在油缸 11的带动下沿 导轨 16上下滚动， 以保证平动托圈 9和下回转支承 6的外圈和内圈的 精确的运动方向。 万向框架 8套设在旋转套筒 4外， 万向框架 8与下 回转支承 6的内圈固定连接，平动托圈 9的上下运动带动下回转支承 6 的内圈上下运动， 从而带动万向框架 8上下运动。 耳轴 12的另一端穿 过耳轴套 13后通过花键与一曲柄 14连接， 曲柄 14的另一端的曲柄尾 轮 34位于万向框架 8的滑槽 81内。 由于旋转套筒 4不能上下运动， 当万向框架 8上下运动时， 滑槽 81带动曲柄尾轮 34上下运动的同时 沿滑槽 81运动， 从而使曲柄 14带动耳轴 12在耳轴套 13内转动， 耳 轴 12的转动带动溜槽 7和溜槽托架 71摆动。
下回转支承 6的内圈固定连接有拨轮组件 37，拨轮组件 37的拨轮 位于旋转套筒 4上开设的上下方向的滑动槽 （图中未示出） 内， 油缸 11通过平动托圈 9带动下回转支承 6上下运动，从而使溜槽 Ί摆动时， 拨轮在旋转套筒 4的滑动槽内相对于旋转套筒 4上下滑动， 当旋转套 筒 4旋转时，拨轮在旋转套筒 4的滑动槽上下滑动的同时随旋转套筒 4 一起旋转， 带动下回转支承 6的内圈和万向框架 8—起旋转， 从而完 成溜槽 7在布料时边旋转边摆动的动作。
作为本实施例的一种优选方案， 如图 1所示， 三个油缸 11分别包 括缸体 94和油缸杆 36， 缸体 94通过油缸支座 93固定在顶盖 2上， 油 缸杆 36的下端通过抱套 92与过渡连杆 15固定连接， 过渡连杆 15的 下端穿过油缸支座 93和顶盖 2伸入到气密箱体 1内， 与气密箱体 1内 的可调连杆 35连接， 可调连杆 35与平动托圈 9连接。 因此， 油缸杆 36的上下运动将带动平动托圈 9上下运动。本实施例的油缸 11的设置 方式为油缸外置式， 也就是油缸杆 36位于气密箱体 1的外部， 或称为 油缸杆 36位于本发明的高炉炉顶溜槽布料器的外部， 从而改变了原有 油缸的油缸杆要伸入到气密箱体内的内置的方式。 当油缸 11出现问题 需要进行拆卸， 以进行检修或更换时， 不需打开布料器本体， 只需将 油缸 11从油缸支座 93上拆下， 然后解开抱套 92， 使油缸杆 36与过渡 连杆 15分开即可， 而无需像内置油缸拆卸时还需要打开布料器那样复 杂， 因此拆卸方便、 快捷， 提高了生产效率。
作为进一步的优选方案， 如图 8和图 9所示， 抱套 92为由对扣在 一起的两瓣抱套本体 95形成的具有中心通孔 96的圆柱状， 两瓣抱套 本体 95通过连接螺栓 97固定在一起， 中心通孔 96的两端的孔径小于 中间部分的孔径， 而在中心通孔 96的变径处形成台阶 100， 油缸杆 36 与过渡连杆 15的相对端分别形成一段细部 101，油缸杆 36与过渡连杆 15的细部 101分别位于中心通孔 96的两端内，两个细部 101的一端分 别连接头 98， 连接头 98均位于中心通孔 96的中间部分并抵靠在台阶 100上， 油缸杆 36与过渡连杆 15的相对端均抵靠在抱套 92的两端。 通过抱套 92将油缸杆 36与过渡连杆 15固定连接在一起。
为了克服现有技术中导轨直接焊接于气密箱体 1 的内壁上， 存在 加工难度大， 导轨热处理难度大， 导轨磨损严重， 寿命变短且当导轨 失效后不可更换等缺点。 作为本实施例的另一种优选方案， 如图 10所 示， 本发明采用可拆卸式的导轨 16， 即在气密箱体 1对应于平动托圈 9的导轮 91的内壁上沿纵向固定连接有槽口朝向导轮 91的定位槽 17， 定位槽 17可以通过焊接的方式固定在气密箱体 1 的内壁上， 导轨 16 (由方钢构成）沿纵向通过多个间隔设置的固定螺栓 18可拆卸式的固 定在定位槽 17内， 当导轨 16磨损严重时， 可以将导轨 16从定位槽 17 上拆卸下来， 换上另一个新的导轨即可， 从而提高了导轨的使用寿命。
作为本实施例的又一种优选方案， 如图 4至图 7所示， 万向框架 8 为铸造成型的异形框架， 万向框架 8包括两个相对且平行的第一边框 82和两个相对且平行的第二边框 83， 且第一边框 82与第二边框 83相 垂直， 相邻的第一边框 82和第二边框 83相对端分别连接第三边框 84 的两端， 即， 第一边框 82、 第二边框 83和第三边框 84依次首尾循环 相接围成封闭的环形， 两个第二边框 83 的中部均向外拱起形成凸台 85， 凸台 85设置的目的在于防止下回转支承 6在水平方向上伸出万向 框架 8，同时凸台 85的设置也为在下面将要描述的连接在耳轴 12上的 端部盖板 20、 外部水管 24的下端以及供油管 30提供设置空间 两个 第二边框 83在凸台 85的同一侧开设两相对的滑槽 81，滑槽 81沿第二 边框 83的长度方向的长度大于滑槽沿第二边框 83宽度的长度， 也即 是滑槽 81为一个长形孔， 曲柄尾轮 34设置于滑槽 81内， 并能在滑槽 81内发生在第一边框 82长度方向的运动。 两个第一边框 82的中部均 设置连接架 86，万向框架 6通过两个对称设置的连接架 86与下回转支 承 6的内圈连接。
由于耳轴 12—直处于高温环境下运行， 为了保证耳轴 12的顺利 运行及使用寿命， 作为本实施例的再一种优选方案， 本实施例针对耳 轴 12 自身进行强制冷却， 以更好的满足耳轴 12在高温环境下顺利运 行的功能需求。 如图 11所示， 从耳轴 12朝向旋转套筒 4外部的一端 向耳轴 12内开设有中心腔室 19 (中心腔室 19未开通至耳轴 12的另一 端） ， 耳轴 12的该一端形成为开口端， 耳轴 12的开口端设置用于盖 住中心腔室 19 的开口的端部盖板 20， 端部盖板 20通过连接螺栓 26 与耳轴 12可拆卸式连接， 并且端部盖板 20与耳轴 12之间设置密封圈 27。 端部盖板 20的中部开设有通孔 （图中未示出） ， 通孔内穿设用于 向中心腔室 19内通入冷却水的进水管， 端部盖板 20上还开设有多个 与中心腔室 19连通的溢流孔 22。 进水管分为位于中心腔室 19内部的 内部水管 23和位于中心腔室 19外部与冷却水源连接的外部水管 24， 内部水管 23的一端一直延伸至靠近中心腔室 19的端部， 以使冷却水 布满整个中心腔室 19。 中心腔室 19内的冷却水对耳轴 12进行冷却后 通过端部盖板 20上设置的溢流孔 22流出， 流出的冷却水最后进入到 如图 1所示的水冷底盘 25上， 并在水冷底盘 25上汇流到布料器的冷 却水系统。 冷却水在中心腔室 19内的具体流动情况如图 11 中箭头所 针对现有技术中耳轴 12与耳轴套 13之间的干磨损无润滑的情况， 作为本实施例的进一步的优选， 向耳轴 12与耳轴套 13之间的摩擦面 注入润滑油， 以有效降低摩擦系数， 进而提高耳轴 12的使用寿命。 具 体结构如图 12所示： 从耳轴 12朝向旋转套筒 4外部的一端向耳轴 12 内开设有过油孔 28， 套设有耳轴套 13处的耳轴 12外壁上开设有连通 至过油孔 28的至少一个油脂出孔 29，过油孔 28与为过油孔 28内提供 润滑油的供油管 30连接。
作为再进一步的优选，如图 12所示，考虑到润滑油注入的均匀性， 油脂出孔 29设置了三个， 三个油脂出孔 29呈一条直线均布在套设有 耳轴套 13处的耳轴 12的外壁上。 而且， 过油孔 28最好靠近耳轴 12 的外壁开设， 最好不要开设在耳轴 12的中部， 而且油脂出孔 29也向 离耳轴 12的外壁较近的一侧开设， 以减少加工难度， 减少油脂流动的 距离。另外，设置油脂出孔 29处的耳轴 12与耳轴套 13为大间隙配合， 故耳轴 12与耳轴套 13的初始状态为线接触， 在运行一段时间后， 耳 轴 12与耳轴套 13之间的线接触转换为窄面接触， 针对此处进行润滑 处理即可有效降低摩擦系数， 进而提高使用寿命。
作为更进一步的优选， 如图 12所示由于上述耳轴 12的润滑无法 通过外部润滑装置提供润滑油， 因此在曲柄 14上固定设置加油器 31， 在旋转套筒 4的外壁上设置碰块 32， 曲柄 14的转动带动加油器 31上 下运动而实现与碰块 32的接触和分离。 为了控制加油量， 在布料器运 行期间采用定周期润滑， 在非润滑周期内， 加油器 31与碰块 32无接 触， 溜槽 81的运行角度控制在 7度到 45度之间。 当进入润滑周期内 时， 溜槽 81的运行角度控制范围发生变化。 针对耳轴 12的润滑实施 在设备运行期间采用定周期润滑， 即布料器布料每十个批次进行润滑 一次， 非润滑时间加油器 31与碰块 32无接触， 当耳轴 12进行到润滑 周期时， 在曲柄 14旋转的过程中， 当溜槽 81的运行角度在 4度时， 加油器 31会与碰块 32发生碰撞， 开始加油， 如图 13所示。 如图 15 所示， 当溜槽 81达到 1度时， 加油器 31加油完毕。 然后碰块 32与加 油器 31分离， 加油器 31停止加油， 即如图 14所示的状态。 溜槽 81 进入下一个加油周期。 通过调节可调连杆 35的长度， 以控制万向框架 8的高度， 从而改变溜槽 81摆动的角度。
下面结合图 1至图 4对本发明的高炉炉顶溜槽布料器的工作原理 和工作过程进行介绍：
要完成布料器的布料， 需要溜槽 7旋转的同时摆动， 以实现均匀 布料。
溜槽摆动的实现方式： 三个油缸 11分别通过过渡连杆 15、可调连 杆 35与平动托圈 9连接， 下回转支承 6的外圈同平动托圈 9通过螺栓 连接在一起， 下回转支承 6的内圈与万向框架 8连接， 当三个油缸 11 的油缸杆 36上下运动时， 带动平动托圈 9、 下回转支承 6和万向框架 8随着做上下运动。 平动托圈 9上下运动过程中靠导轮 91与气密箱体 1的导轨 16配合， 形成滚动摩擦， 气密箱体 1的导轨 16对导轮 91的 运动起到限位作用。 装配到万向框架 8的滑槽 81 内的曲柄尾轮 34随 万向框架 8—同动作， 装在耳轴 12外侧的曲柄 14带动耳轴 12在旋转 套筒 4的耳轴套 13内做相应幅值的转动动作。 而耳轴 12的另外一端 通过花键与溜槽托架 71配合， 至此， 溜槽 7与溜槽托架 71在耳轴 12 的花键传递的动力作用下随曲柄 14作同步摆动。
溜槽 7旋转的实现方式： 顶盖 2的大法兰与气密箱体 1固定连接， 顶盖 2下部的小法兰与上回转支承 5的内圈连接， 上回转支承 5的外 圈与旋转套筒 4固定连接， 两个耳轴 12安装在开设在旋转套筒 4上的 耳轴孔的耳轴套 13内， 耳轴 12—端花键与曲柄 14连接， 另一端花键 与溜槽托架 71连接， 也就是说溜槽托架 71通过耳轴 12挂在了旋转套 筒 4上。溜槽水平传动装置 10安装在顶盖 2上， 溜槽水平传动装置 10 的动力由减速电机 99提供， 当溜槽水平传动装置 10通过小齿轮驱动 上回转支承 5的外圈旋转时， 旋转套筒 4随上回转支承 5的外圈旋转， 溜槽托架 71也就随旋转套筒 4转动， 安装在溜槽托架 71上的溜槽 7 随之转动。
溜槽 7旋转和摆动同时进行的实现方式： 由图 1所示， 拨轮组件 37安装在下回转支承 6的内圈上， 所以拨轮组件 37可以随平动托圈 9 上下运动，拨轮组件 37的拨轮可以在旋转套筒 4的滑动槽内上下滚动， 而当旋转套筒 4旋转时， 拨轮组件 37随同旋转套筒 4一同旋转， 从而 拖动万向框架 8随动， 此时下回转支承 6的内圈同做周向旋转运动。 由于油缸 11通过可调连杆 35拖动平动托圈 9上下运行，下回转支承 6 的外圈与平动托圈 9 固定连接而保持相对静止， 又由于下回转支承 6 的内圈、 外圈在竖直方向相对无运动， 所以使得万向框架 8做上下运 行， 曲柄尾轮 34在万向框架 8的滑槽 81 内随万向框架 8向上运动， 由于旋转套筒 4不能上下运动， 使得曲柄 14带动耳轴 12在耳轴套 13 内转动， 耳轴 12的转动带动溜槽 7及溜槽托架 71作定幅值摆动。 至 此溜槽 7随溜槽托架 71完成了旋转与摆动动作的有机合成。
以上实施例仅为本发明的示例性实施例， 不用于限制本发明， 本 发明的保护范围由权利要求书限定。 本领域技术人员可以在本发明的 实质和保护范围内， 对本发明做出各种修改或等同替换， 这种修改或 等同替换也应视为落在本发明的保护范围内。
