用于海底跨接管道下放安装的装置
摘要：
本发明提出一种用于海底跨接管道下放安装的装置，用于对接海底管道与跨接管道，所述用于海底跨接管道下放安装的装置包括：支撑底架(3)；初步对中海底管道的管道卡箍(1)，设置在所述支撑底架(3)上，所述管道卡箍(1)具有容纳所述海底管道的空腔(10)；上部支撑框架(2)，连接在所述支撑底架(3)的上方；管道夹持机构(4)，包括夹持所述跨接管道的管道夹(48)和与所述管道夹(48)连接的夹持液压缸(46)，所述管道夹持机构(4)可上下移动的连接在所述上部支撑框架(2)上，并且所述管道夹(48)可前后移动和左右移动的设置在所述上部支撑框架(2)上。本发明确保了下放安装跨接管道中的精确性。
摘要（英）：

The invention provides a device for lowering and mounting a submarine pipeline and a crossing pipeline. The device for lowering and mounting the submarine pipeline and the crossing pipeline is used for butting a submarine pipeline and a crossing pipeline, and comprises a support underframe (3), a pipeline clamp (1) for preliminarily centering the submarine pipeline, an upper support frame (2) and a pipeline clamping mechanism (4), wherein the pipeline clamp (1) is arranged on the support underframe (3) and is provided with a cavity (10) for accommodating the submarine pipeline; the upper support frame (2) is connected above the support underframe (3); the pipeline clamping mechanism (4) comprises a pipeline clamp (48) for clamping the crossing pipeline and a clamping hydraulic cylinder (46) which is connected with the pipeline clamp (48); the pipeline clamping mechanism (4) can move up and down and is connected to the upper support frame (2); and the pipeline clamp (48) can move back and forth and from side to side and is arranged on the upper support frame (2). By the device, the accuracy of lowering and mounting the submarine pipeline and the crossing pipeline is ensured.
