以下结合附图对本发明进行详细描述。
如图1所示，本发明公开一种双辊薄带连铸侧封板安装装置，用于将侧封板1固定贴附在两铸辊12位于同一侧的端面上，使侧封板1及铸辊12能够共同形成四周封闭的钢水熔池。该侧封板1安装装置包括：
具有一容置空间以用于容置、定位侧封板1的定位装置3；
用于驱动定位装置3在铸辊靠近和背离铸辊12端部的方向上直线移动的驱动装置2；
以及通过驱动装置2调控定位装置3的移动位置以使侧封板1能够与铸辊12的端部相贴合或分离的控制系统。
进一步地，控制系统包括处理器10和用于监测定位装置3的移动位置的位置传感器9。该位置传感器9与处理器10电连接，以使其能够向处理器10实时或定时反馈定位装置3的位置信息。例如，使用者根据侧封板1的装设点位置在处理器10中预设定位装置3的安装位，使定位装置3在驱动装置2的驱动下移动至安装位时向处理器10发送信号，以使处理器10通过调控驱动装置2令定位装置3停止移动并保持在该位置。
优选地，控制系统还包括用于在侧封板1与铸辊12的端部相贴合时检测二者间压力的压力传感器8。该压力传感器8与处理器10电连接，以使其能够向处理器10实时或定时反馈压力值，使处理器10可根据接收到的压力值判定侧封板1与铸辊12间是否紧密贴合。使用者具体可根据实际情况在处理器10中预设侧封板1与铸辊12的端面之间紧密贴合时的压力值，使处理器10可通过比对压力传感器8实时检测到的侧封板1与铸辊12的端面之间的压力值与预设压力值是否一致来判定侧封板1与铸辊12的端面是否紧密贴合。若压力传感器8检测到的压力值小于预设压力值，处理器10则判定侧封板1与铸辊12的
端面之间未紧密贴合，故调控驱动装置2继续驱动定位装置3向铸辊12的端面运动，或令驱动装置2增加驱动力继续驱动定位装置3运动使其与铸辊12的端面紧密贴合，直至检测到侧封板1与铸辊12的端面之间的压力值达到预设压力值。若压力传感器8检测到的压力值与预设压力值相同，处理器10则判定侧封板1与铸辊12间已紧密贴合，便调控驱动装置2使其保持现有的驱动力以持续驱动定位装置3从而定位定位装置3，也就是驱动装置2持续向定位装置3施加驱动力使侧封板1和铸辊12保持紧密贴合，这样定位装置3便时刻受到铸辊12的端面向其施加的与上述驱动力数值相等的反推力进而达到定位的效果。
本实施例中的驱动装置2为驱动油缸(当然，驱动装置2也可为其他直线驱动机构)。位置传感器9设于驱动油缸的缸体上，压力传感器8设于驱动油缸的活塞杆朝向铸辊12的一端并与定位装置3固定连接。处理器10为外设件，其通过与其电连接并同时与驱动油缸相连的伺服阀11调控驱动油缸。也就是处理器10通过调控伺服阀11的开度控制流入驱动油缸内的液压油，进而控制活塞杆的运动速度，以达到调节驱动油缸的驱动力的效果。
结合图2至图4所示，定位装置3为支撑座，其包括多个限位件和与铸辊12的端面相平行的安装板4。上述驱动油缸的活塞杆设有压力传感器8的一端与安装板4背离铸辊12的一侧连接。该多个限位件围设于安装板4上以与安装板4配合形成上述用于容置、定位侧封板1的容置空间。也就是侧封板1通过各限位件固定贴靠在安装板4上，以使其保持在与铸辊12的端面相平行的位置上。采用上述结构的支撑座安装定位侧封板1时操作简单快捷，安装侧封板1时仅通过机械手将其垂直插入上述容置空间内即可实现侧封板1的安装及定位，无需设置额外的固定件，如陶瓷螺栓等；更换或移取侧封板1时，同样通过机械手将其抽拔出上述容置空间便可，十分快捷方便，有效改善了侧封板1由于定位时间较长而大量温降的弊端。(机械手以及其他外设固定件本文不涉及，因此未作展开说明。)
优选地，该安装板4与侧封板1外形匹配，以使二者能够较好的贴合在一起，也就是在节省材料的同时最大限度的增加二者的接触面
积，使在驱动油缸活塞杆向安装板4施加顶推力(即驱动力)时安装板4能够近乎完全的将该顶推力传至侧封板1上，减少力的流失，从而保证该顶推力能够使侧封板1与铸辊12紧密贴合，即，使侧封板1与铸辊12的端面间的压力值满足预定要求。
继续结合图2所示，本实施例中的侧封板1的形状近似为倒置的三角形，其中三角形的两条侧边(即分别与该三角形的底边相连的两条边)均相向内凹形成圆弧形。
限位件包括托块5、两个抱爪6和两个弧形限位板7。其中，托块5设于侧封板1的底部用于撑托侧封板1；两个抱爪6分别设于侧封板1的两侧的顶部以用于限制侧封板1，其主要是限制侧封板1在垂直安装板4板面的方向上的位置，而为了方便侧封板1吊装至支撑座中，该抱爪6与安装板4之间的距离应稍大于侧封板1的厚度，使侧封板1位于支撑座内时，侧封板1与抱爪6间需留有一定间隙，本实施例中侧封板1与抱爪6间的间隙至少为1mm；两个弧形限位板7分别设于侧封板1的两侧的中部，也就是托块5与每一个抱爪6间均设有一弧形限位板7，该弧形限位板7的圆弧半径要稍大于侧封板1的弧形侧边的圆弧半径，如两半径差为0.5mm-1mm，以方便侧封板1的装设。进一步地，该弧形限位板7的设置主要是用于限制侧封板1在平行安装板4板面的方向上的位置，防止其偏移。本实施例中的两个抱爪6和两个弧形限位板7均对称设置，以更好的限位侧封板1。本实施例中，当侧封板1装设于支撑座内时，两个弧形限位板7与侧封板1间保持不小于0.5mm的间隙。另外，托块5、抱爪6和弧形限位板7的材料均为耐高温材料，如为陶瓷或耐高温合金。
为了使侧封板1能够与铸辊12的端面相贴合，侧封板1需在其装设于支撑座中时保证其朝向铸辊12的一面凸出弧形限位板7及托块5，本实施例中侧封板1在朝向铸辊12的方向凸出托块20mm。同时，如图8所示，在侧封板1与铸辊12的端面贴合时，两抱爪6均位于铸辊12的辊面上部(该上部即为图中的上部)，避免抱爪6接触到铸辊12，影响侧封板1的密封效果。
本发明同时公开一种采用上述双辊薄带连铸侧封板安装装置安装侧封板的方法，也就是通过上述安装装置将侧封板1装设在铸辊12的
端面上并投入浇铸使用的方法，其具体包括步骤：
1)将控制系统中的处理器10的处理模式调整为主要根据对比位置传感器9实时监测到的定位装置3的位置是否为预定位置从而判定是否需要调控驱动装置2(本实施例中的驱动装置2为驱动油缸，以下称驱动装置为驱动油缸)的位置控制模式，接着在处理器10中预设作为安装位的第一预定位置和作为调整位的第二预定位置，以在定位装置3移动至安装位和调整位时，处理器10可根据位置传感器9向其反馈的位置信号迅速调节伺服阀11以控制驱动油缸使其停止驱动，即，使定位装置3停止在安装位或调整位上；本实施例中调整位的位置为侧封板1与铸辊12的端面间的距离为2mm-10mm处；
2)如图5所示，待定位装置3定位在安装位时，操作者将侧封板1通过机械手或其他设备将其装设在定位装置3中；
3)如图6所示，侧封板1被装设在定位装置3中以后，处理器10继续调控驱动油缸使其驱动定位装置3由安装位移动至邻近铸辊12的端部的调整位处停止；
4)调整处理器10的处理模式使其同时处于位置控制模式和可根据比对检测到的侧封板1与铸辊12端面间的接触压力值是否为预定压力值从而判定是否对驱动油缸进行调控的压力控制模式(也就是此时处理器10兼容位置控制模式和压力控制模式)，接着在处理器10中预设在侧封板1与铸辊12端面贴合时定位装置3所处位置的位置数据(本实施例将该位置定义为作为浇铸位的第三预定位置)，并在处理器10中预设当定位装置3移动至浇铸位时侧封板1与铸辊12间的第一压力值F1以及压力值大于F1的第二压力值F2，以使处理器10可根据压力值F1和F2的大小通过调节伺服阀11的开度而相应调节驱动油缸的驱动力；该步骤的设置是为了使侧封板1与铸辊12的端面之间距离较小时再以与预设压力(即第一压力值F1和第二压力值F2)相适配的驱动力驱动定位装置3移动以使侧封板1与铸辊12的端面间对应贴合，该种方式相比自定位装置3于安装位时起便以上述驱动力驱动定位装置3移动更能够精确控制驱动力，有效避免侧封板1因与铸辊12间产生较大的碰撞力而损坏的状况发生；另外，为了避免侧封板1的温度降低，定位装置3在调整位停留的时间通常为5s-10s；
5)待处理器10完成模式调节后，且浇铸准备工作完成时，浇铸系统向处理器10发出动作命令，此时处理器10迅速调节伺服阀11，使驱动油缸按对应压力值F1预设的驱动力驱动定位装置3，使其移动至与铸辊12相贴靠的浇铸位；
如图7所示，当位置传感器9检测到定位装置3移动至浇铸位，且压力传感器8检测到侧封板1与铸辊12端面间的压力值为F1时，处理器10根据预设的第二压力值F2调节伺服阀11，使驱动油缸施加在定位装置3上的驱动力逐渐加大从而增加侧封板1与铸辊12的端面间的接触压力，待压力传感器8检测到侧封板1与铸辊12端面间的压力值为F2时，处理器10调控驱动油缸使其保持该顶推力恒定并持续顶推定位装置3，此时侧封板1便紧密且稳定的贴附于铸辊12的端面上了。
进一步地，当侧封板1与铸辊12的端面紧密贴合时，也就是两者间的压力值为F2时，为了定位侧封板1的位置，驱动油缸需向定位装置3提供持久的顶推力以使侧封板1时刻与铸辊12的端面紧密贴合，具体可采取以下两种方式：
1)令处理器10通过比对压力传感器8实时反馈的压力值与第二压力值F2间的数量关系而相应调节伺服阀11的开启角度，以使驱动油缸向定位装置3提供能够使侧封板1与铸辊12端面间的压力值恒为F2的顶推力(或至少为F2的顶推力)，进而定位侧封板1；
2)操作者将侧封板1与铸辊12间的压力值为F2时定位装置3的精确位置(该位置可能与浇铸位存在些许位置误差，但是该位置误差在正常的误差范围内)预先存储在位置传感器9和处理器10中，使处理器10通过比对位置传感器9实时反馈的检测数据与预定位置间的位置关系而相应调节伺服阀11，以使驱动油缸可根据定位装置3的实际位置向定位装置3提供相适配的驱动力，进而使定位装置3恒处于铸辊12与侧封板1间压力值为F2时的位置。
优选地，由于铸辊12在工作时会周期性的产生一定结构变化，为了配合铸辊12的结构变化，操作者可根据铸辊12的变化周期在处理器10中预设一时间段(当然，也可选择通过其它机构进行时间控制，本实施例中预设的一时间段为1min-5min)，接着通过上述两种方式使
侧封板1与铸辊12的端面之间的压力值在该时间段内恒为F2，待该时间段期满时，处理器10便调控驱动油缸2使其施加在定位装置3上的顶推力逐渐减小，以使侧封板1与铸辊12的端面间的压力值逐渐减小，待二者间的压力值减小为F1时，处理器10调控驱动油缸2以与压力值F2相对应的驱动力驱动定位装置3以使侧封板1紧密贴附于铸辊12的端面上，待二者间的压力值为F2时，处理器10继续调控驱动油缸2以使侧封板1与定位装置3间的压力值在上述时间段内继续保持在F2，周而复始，以使侧封板1与铸辊12的端面间的压力值在F1与F2之间周期性变换。
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。
