具体实施方式
下面结合附图和实施例对本发明的技术方案进一步说明。
如图1-图3所示，一种用于核聚变环境下大型重载部件的吊装机构，包括基架1、一对吊臂5、一对圆弧臂2。在基架1的顶部四角位置分别设有吊耳6，在基架1内的前部位置设有顶部电机7，在基架1内的后部位置设有一对旋转电机8。上述一对吊臂5分列于基架1的左右两侧并彼此相对，在各吊臂5的上部固定安装有与第一连接件5-2固定连接的第二连接件5-3，各吊臂5的下部向下延伸至超过基架1的底部，且各吊臂5的下端彼此相对的侧面分别成型为凸面，在凸面分别转动安装有滚轮4。此外，顶部电机7的输出轴传动连接有第一齿轮11-1，在基架1的底部且在第一齿轮11-1的前后两侧分别设有沿基架1的左右方向延伸的卡槽9，上述第一连接件5-2卡装于该卡槽9中，在卡槽9内能够滑动。即，吊臂5、第一连接件5-2、第二连接件5-3三者固定连接为一体，且因为卡槽9分别位于第一齿轮11-1的前后两侧，所以滑动卡装于各卡槽9内的上述第一连接件5-2实际上也位于第一齿轮11-1的前后两侧。换句话说，卡装于卡槽9中的第一连接件5-2隔着第一齿轮11-1彼此相对。此外，在各第一连接件5-2的相对面分别 设置有第一齿条5-1，上述第一齿轮11-1能够同时与该第一齿条5-1传动啮合。由此，顶部电机7的动力经由第一齿轮11-1被传递至第一齿条5-1，并带动第一连接件5-2在各自的卡槽9内相对地往复滑动，从而实现两个吊臂5相对地进行反向运动。换句话说，两个吊臂5能够沿基架1的左右方向彼此接近或远离，以实现利用下端的滚轮4对偏滤器13进行的夹持和释放。两个圆弧臂2分列于基架1的左右两侧，每个圆弧臂2的外弧面朝上，每个圆弧臂2中分别设有随圆弧臂形状的弧形槽2-2，弧形槽2-2分别左右贯通所在圆弧臂2，每个圆弧臂2的外弧面上分别设有随圆弧臂2形状的第二齿条2-1，第二齿条2-1的弧向长度小于圆弧臂2外弧面的弧向长度，在基架1的两侧，圆弧臂2的中心线上分别各自设有两个支撑点3，每侧圆弧臂2分别通过其弧形槽2-2滑动装配于对应侧各个支撑点3，圆弧臂2的一端向前上方延伸，圆弧臂2的另一端向后下方延伸至超过基架1底部，且在两个圆弧臂2的另一端分别安装有连接件2-3，吊臂5下端的滚轮4的中心与对应侧圆弧臂2所在圆同心。基架1的左右两侧对应旋转电机8位置还分别转动安装有第二齿轮10，第二齿轮10分别与对应侧圆弧臂2的外弧面上的第二齿条2-1传动啮合，两个旋转电机8的输出轴分别与两个第二齿轮10一一对应而传动连接。
支撑点3为转动安装于基架1对应侧的转轮，转轮分别位于对应侧圆弧臂2的弧形槽2-2中，由此形成对圆弧臂2的支撑。
顶部电机7的输出轴与一个90度转角第一减速机11的输入轴连接，90度转角减速机11的输出轴固定安装第一齿轮11-1。由第一齿轮11-1驱动两侧的第一齿条5-1而带动第一连接件5-2的滑动，通过第一连接件5-2的滑动，经过第二连接件5-3使吊臂5完成伸出和缩回(两个吊臂5相对地进行反向运动，能够沿基架1的左右方向彼此接近或远离)，每个旋转电机8的输出轴分别各自与90度转角减速机12的输入轴连接，两个90度转角第二减速机12的输出轴与两个第二齿轮10一一对应地同轴连接。
如图5所示，转运时，通过两个吊臂5、两个圆弧臂2共同夹持偏滤器13。如图6所示，当需要偏滤器13转动时，使圆弧臂2伸长，即可实现偏滤器13转动。
本发明所述的实施例仅仅是对本发明的优选实施方式进行的描述，并非对本发明构思和范围进行限定，在不脱离本发明设计思想的前提下，本领域中工程技术人员对本发明的技术方案作出的各种变型和改进，均应落入本发明的保护范围，本发明请求保护的技术内容，已经全部记载在权利要求书中。
