Description

一种海洋钻井平台用自动翻板机构
技术领域
本发明涉及深水海洋石油钻井设备， 尤其涉及多种设备配合作业时设备 运行轨迹与行走通道存在干涉的情况下， 一种翻转钻井平台的自动翻板机构。 背景技术
在钻井平台和钻井船上， 需要多个设备配合完成各项任务， 每个设备都 需要操作、 保养和维护等人工操作， 这就需要设置供操作人员和维修人员行 走的行走通道。 然而由于钻井平台和钻井船上的空间有限， 经常会出现设备 运行轨迹与行走通道相互干涉的情况。 例如在下放和回收隔水管时， 需要隔 水管吊机和隔水管猫道配合完成作业。 由于空间的限制， 隔水管吊机与隔水 管猫道的轨道有交叉， 隔水管吊机的运行轨道会与隔水管猫道的走道发生干 涉。
为了避免这种干涉情况的发生， 现有技术中通常会将行走通道与设备运 行轨迹干涉部分的行走通道设计为可翻转平台， 在设备运行到该处时， 将干 涉处的翻转平台翻转， 待设备通过后， 再将翻转平台放下， 从而保证行走通 道的顺畅。
目前的可翻转平台通常设计为以下两种：
第一种： 平时采用翻转状态， 行人需要通过时， 由通过者手动放下可翻 转平台， 通过后再将平台翻转， 这样增加了通过者的劳动强度， 而且万一出 现通过者通过后忘记翻转平台的情况， 就会出现设备运行时撞击平台的事故; 此外， 在危机情况下通过翻转平台处时， 需要花费时间放下平台， 增加了人 员逃生的时间； 而且行走通道的不顺畅也存在安全隐患。
第二种： 采用液缸等其它控制原件控制可翻转平台的翻转和下放， 通过 与运行设备的配合， 实现自动控制翻转平台的翻转和下放， 使可翻转平台在 设备不通过时处于畅通状态。 该设计虽然降低了劳动强度， 但是这样增加了 液压、 电气等控制原件及其相关线路， 同时使控制系统变得复杂， 亦增加了 较多的故障点； 若系统或者控制原件出现故障， 可能会出现可翻转平台处无 法通过的情况； 而且这种方法也很大程度上增加了生产使用成本。
发明内容
为了解决现有技术中的问题， 本发明的目的是提供一种无需液压、 电气 控制元件， 劳动强度低， 可靠性能高的海洋钻井平台用自动翻板机构。 该自 动翻板机构利用独特的机械结构设计满足自动翻板的要求， 同时无需液压、 电气等控制元件。
为实现上述目的， 本发明采用以下技术方案： 一种海洋钻井平台用自动 翻板机构沿隔水管吊机运行轨道方向安装在隔水管吊机靠近可翻转平台一 侧， 所述自动翻板机构由钢管悍接成梯形结构组成， 且该梯形自动翻板机构 的下底端低于可翻转平台的最下端。
采用以上结构， 当隔水管吊机运行至与行走通道干涉处（可翻转平台处) 时， 自动翻板机构的下底端前部伸入可翻转平台下方， 随着隔水管吊机的继 续前进， 可翻转平台沿着梯形自动翻板机构的腰被缓慢抬起， 且该可翻转平 台被翻开后由自动翻板机构支撑， 由于梯形自动翻板机构的高度满足翻转后 的可翻转平台不干涉隔水管吊机 （通常梯形的高度大于隔水管吊机可能与可 翻转平台发生干涉部分的隔水管吊机的高度）， 保证了隔水管吊机顺利通过行 走通道干涉处。 隔水管吊机通过后， 可翻转平台沿着自动翻板机构的曲线， 顺着梯形的另一条腰被缓慢放下至可翻转平台处于水平位置 （即恢复到初始 状态） ，随着隔水管吊机的行走， 自动翻板机构的下底端后部自动脱离可翻转 平台， 保证行走通道的畅通。 当隔水管吊机反向运行时， 其运行到行走通道 干涉处 （可翻转平台） 的运动过程与前述雷同， 在此不再赘述。 本发明不但 能够保证行走通道和隔水管吊机的运行轨迹不发生干涉， 避免设备运行过程 中出现撞击平台的事故， 消除安全隐患， 保证紧急情况下逃生安全， 而且不 需要人工手动掀起或者放下可翻转平台， 降低了劳动强度。 同时由于本发明 采用纯机械结构， 无需液压和电气等控制原件， 节约了制造和使用成本， 且 可靠性高。
所述梯形自动翻板机构的高度为可翻转平台长度的 0. 5〜0. 86倍。 采用 此种结构， 自动翻板机构在打开和放下可翻转平台的时候， 不但不会干涉隔 水管吊机， 而且可翻转平台也不会产生 "过翻的现象"（翻转超过了 90度， 无法自动下放回来）。
优选方案为， 所述自动翻板机构通过连接板与隔水管吊机连接， 连接板 与自动翻板机构悍接连接， 连接板与隔水管吊机采用螺栓连接。 通过增加的 连接板连接， 增强了自动翻板机构与隔水管吊机的连接刚性， 使本发明的自 动翻板机构更加牢固。
进一歩的优选方案， 所述梯形自动翻板机构为等腰梯形结构， 且梯形的 两条腰与梯形的上底之间均采用弧形圆滑过渡。 采用此种结构， 使自动翻板 机构在打开或者放下可翻转平台的过程中， 运动平稳， 不会出现跳动等冲击 现象。
所述等腰梯形自动翻板机构的腰与下底之间的夹角 α为 30〜50度。 采用 此种结构， 当需要打开可翻转平台时， 自动翻板机构与可翻转平台相抵后， 能够轻易使可翻转平台抬起， 避免因为出现抵死而掀翻不了可翻转平台的情 况出现。
附图说明
以下结合附图和具体实施方式来进一歩详细说明本发明：
图 1为本发明的自动翻版机构未打开可翻转平台前的立体结构示意图； 图 2为图 1中 Α部分的放大结构示意图；
图 3为本发明的自动翻版机构打开可翻转平台过程中的立体结构示意图; 图 4为本发明的自动翻版机构放下可翻转平台后的立体结构示意图； 图 5为本发明的自动翻板机构安装在隔水管吊机上的正视结构示意图。 具体实施方式 如图 1至图 5之一所示， 本发明一种海洋钻井平台用自动翻板机构 1沿 隔水管吊机 2的运行轨道 3的方向安装在隔水管吊机 2靠近可翻转平台 4一 侧， 所述自动翻板机构 1由钢管悍接成梯形结构组成， 且该梯形自动翻板机 构 1的下底端 12低于可翻转平台 4的最下端， 所述梯形自动翻板机构 1的高 度满足翻转开可翻转平台 4时， 可翻转平台 4不会与隔水管吊机 2发生干涉。 在本实施例中，所述梯形自动翻板机构 1的高度为可翻转平台 4长度 L的 0.5〜 0.86倍。所述自动翻板机构 1还通过连接板 5与隔水管吊机 2连接， 连接板 5 与自动翻板机构 1悍接连接， 连接板 5与隔水管吊机 2采用螺栓连接。 其中， 虽然术语 "连接板"， "连接耳板"， "连接杆"和 "连接件"通常是可交换的 并且可以交替使用， 且使用这些术语中任何一个也就涵盖了其他。 通过增加 的连接板 5连接， 增强了自动翻板机构 1与隔水管吊机 2的连接刚性， 使本 发明的自动翻板机构 1更加牢固。 所述梯形自动翻板机构 1为等腰梯形结构， 且梯形的两条腰 61、 62与梯形的上底 7之间均采用弧形圆滑过渡。 所述等腰 梯形自动翻板机构 1的腰与下底之间的夹角 α为 30〜50度。 本实施例中该夹 角 α为 40度。 采用此种结构， 使自动翻板机构 1在打开或者放下可翻转平台 4的过程中， 运动平稳， 不会出现跳动等冲击现象。
本发明的工作过程如下： 当隔水管吊机 2沿着运行轨道 3运行至与行走 通道 8的干涉处 （也就是设计的可翻转平台 4处） 时， 自动翻板机构 1的下 底端 12前部伸入可翻转平台 4下方， 随着隔水管吊机 2的继续前进， 可翻转 平台 4沿着梯形自动翻板机构的腰 61被缓慢抬起， 且该可翻转平台 4被翻开 后由自动翻板机构 1支撑， 由于梯形自动翻板机构 1的高度满足翻转后的可 翻转平台 4不干涉隔水管吊机 2 (通常梯形的高度大于隔水管吊机 2可能与可 翻转平台 4发生干涉部分的隔水管吊机 2的高度）， 保证了隔水管吊机 2顺利 通过与行走通道 8的干涉处。 隔水管吊机 2通过后， 可翻转平台 4沿着自动 翻板机构 1的曲线， 顺着梯形的另一条腰 62被缓慢放下至可翻转平台 4处于 水平位置 （即恢复到初始状态） ，随着隔水管吊机 2的行走， 自动翻板机构 1 的下底端 12后部自动脱离可翻转平台 4， 保证行走通道 8的畅通。 当隔水管 吊机 2反向运行时， 其运行到行走通道 8干涉处 （可翻转平台） 的运动过程 与前述雷同， 在此不再赘述。
