Abstract

The invention discloses a subsea pipeline maintenance pipe-lifting frame. The subsea pipeline maintenance pipe-lifting frame comprises two supporting seats, two supporting legs, a cross beam and a jawmechanism, wherein the two supporting seats are arranged at intervals in an opposite mode, the two supporting legs are separately installed on the two supporting seats, the cross beam is connected between the two supporting legs and can move back and forth along the supporting legs in the vertical direction, and the jaw mechanism is installed on the cross beam. The jaw mechanism comprises a vertical axis unit connected with the cross beam, a horizontal axis unit connected with the vertical axis unit and a pipe-gripping claw unit arranged on the horizontal axis unit, facing downwards and capable of clamping a subsea pipeline in opening and closing modes. According to the subsea pipeline maintenance pipe-lifting frame, the subsea pipeline can be lifted to the design height from the seabed so as to perform maintenance on the damaged section of the subsea pipeline. The subsea pipeline maintenance pipe-lifting frame can be operated by an underwater robot and is suitable for deep sea subseapipeline maintenance.

本发明公开了一种海管维修提管架，包括相对间隔设置的两个支座、分别安装在两个所述支座上的两个支腿、连接在两个所述支腿之间并可沿所述支腿在垂直方式上来回移动的横梁、安装在所述横梁上的卡爪机构；所述卡爪机构包括连接所述横梁的竖轴单元，连接所述竖轴单元的横轴单元，设置在所述横轴单元上且朝下设置、可开合夹持海管的抱管爪单元。本发明的海管维修提管架，实现水下将海管从海床上提起至设计高度，以便开展对海管破损段进行维修。该海管维修提管架可通过水下机器人操作，适用于深水海管维修。
