以下参照附图对本发明的结构做进一步描述。
图 1、 2、 3、 4示出了一种液压顶推装置的结构图。 图中, 对于滑道移位系 统, 液压顶推装置安放在下滑道 1上, 下滑道 1与地面基础固定连接, 上滑板 10与平移的物体 (船舶与海洋结构物)连接,采用液压顶推装置让上滑板 10在下 滑道 1上移动。 液压顶推装置包括一个液压站 6、 后座 7、 前座 9、 引撬机构、 自动纠偏机构和无扭矩顶推机构, 液压站 6和后座 7共同设置在一个后座平台 17上, 后座平台 17的下放两侧各设有 3个滚轮 4, 前座 9经连接法兰 10a与上 滑板 10成固定连接。
无扭矩顶推机构采用二个液压缸 8, 液压缸 8的一端通过第三销轴 8b与后 座 7成铰链连接, 另一端通过第二销轴 8a与前座 9成铰链连接。 无扭矩机构设
用点和棘爪 5与挡块 2间的力作用点共线。 棘爪轴 13与前圆块 14接触面的母 线垂直上述三个作用点的连线。
自动纠偏机构采用一个自动纠偏控制杆 11和二个纠偏定位块 12,自动纠偏 控制杆 11的一端与前座 9成固定连接, 另一端夹在固定于后座 7上的二个纠偏 定位块 12的中间。 自动纠偏控制杆 11的两侧各设有一个与前座 9成固定连接 的斜支撑杆 lla。当上滑板 10有小角度偏移时,因前座 9与上滑板 10固定连接, 使得前座 9也偏移一定的角度, 这样带动自动纠偏控制杆 11偏移, 而自动纠偏 控制杆 11偏移拨动纠偏定位块 12,使得顶推装置也跟着偏移。在顶推时因有小 角度偏移, 通过棘爪 5—边抓紧另一边放松, 就可以顶上滑板 10的一边, 从而 恢复上滑板 10的小角度偏移, 也起到纠偏作用。
引撬机构采用二个棘爪 5、 一个棘爪轴 13、 二个引撬 3和二排等距离布置 的档块 2, 棘爪轴 13设置在档板 18与紧靠后座 7的前圆块 14之间。 档块 2固 定设置在下滑道 1上, 并与棘爪 5的位置相对应。 棘爪轴 13接触前圆块 14的 下部设有一个下压块 15, 上部设有一个上压块 16。 棘爪 5套装在棘爪轴 13的 两端, 并采用棘爪轴套 13a固定。 每个棘爪 5中部通过第一销轴 3a与骑跨在档 块 2上的引撬 3成铰链连接, 引撬 3采用放置在挡块 2两侧的板构成,在引撬 3 上设有一个供第一销轴 3a用的长销轴孔。棘爪抓钩前下端面与挡块 2后上端面 相配合, 且没有顶角, 可以使得棘爪 5顺利地沿挡块 2上沿向前移动。 棘爪抓 钩后端面与挡块 2前端面紧密配合, 可以阻挡棘爪 5向后移动。 在引撬 3上开 一个特殊的长销轴孔, 这个长销轴孔在前后方向上可以让引撬 3和棘爪 5一起 联动, 而在上下方向上只能让棘爪 5上下运动, 而引撬 3是不能联动的, 也就 是说引撬 3只能前后动, 棘爪 5可以上下前后动。 这样就可以让棘爪 5沿着挡 块 2布置的方向运动。
当液压缸 8顶升时, 棘爪 5抓紧挡块 2, 液压缸 8推着上滑板 10前行。 当 液压缸 8收缩时, 因前座 9与负有重载的上滑板 10固定, 使得后座平台 17与 液压装置前移,棘爪轴 13带动棘爪 5,棘爪 5连同棘爪 5上的第一销轴 3a顶着 引撬 3前移, 引撬 3在公差范围内贴着挡块 2前行; 当棘爪 5前端接触到挡块 2 时, 棘爪 5沿着挡块 2的上表面, 一边向上移动一边向前移动, 棘爪 5连同第 一销轴 3a—边在引撬 3上开的长销轴孔上移, 〜边顶着引撬 3前移。 当棘爪 5 移过挡块 2时, 棘爪 5连同第一销轴 3a沿着引撬上开的长销轴孔下落。 当液压 缸 8再次顶升时, 将重复上属顶推过程。
