Problems solved by technology

[0004] At present, the submarine pipeline installation project requires staff to dive into the seabed for a long time for manual observation and inspection. Due to the harsh working environment on the seabed, the inspectors have a high risk of work, it is difficult to guarantee the detection accuracy, and the detection efficiency is low.

Abstract

The invention discloses a subsea pipeline installation servo robot, which is suitable for the socket and socket of the submarine large-tonnage pipeline, and is mainly composed of a socket and socket mechanism, an insertion mechanism, a feeding mechanism and a monitoring system. The insertion mechanism and the socket mechanism of the present invention can make it in close contact with the insertion pipe and the socket pipe, the axis between the pipes is adjusted to be collinear by the hybrid servo control of the force and position of the hydraulic cylinder, and the feeding mechanism is controlled by the position servo of the hydraulic cylinder. The control enables the two pipes to complete the socket and socket action, and the monitoring system can monitor the underwater operation site, the position control of the pipe axis, and the position accuracy of the socket and socket during the operation of the robot. Compared with the prior art, which relies on manual diving into the seabed for operation, which cannot guarantee personnel safety, socket and socket accuracy, and work efficiency, the present invention can accurately, efficiently and continuously complete the operation of multiple pipelines in the harsh working environment of the seabed. The connection is safe, convenient, reliable and widely applicable.

Description

technical field [0001] The invention relates to the technical field of subsea pipeline installation, in particular to a subsea pipeline installation servo robot, which is mainly used for sockets and sockets of large-tonnage submarine pipelines. Background technique [0002] With the continuous increase of energy demand and the continuous advancement of marine engineering technology, various types and diameters of submarine pipelines have been successfully laid all over the world, with a total length of tens of thousands of kilometers, and submarine pipelines are increasingly important for energy transmission. [0003] There are many types of submarine pipelines. For pipelines that are not easy to weld, such as fiberglass steel pipes, when the pipeline socket is carried out on the seabed, it is difficult to ensure the coaxiality of the insertion pipe and the socket pipe and the angle of the pipeline interface due to the influence of seawater fluctuations and poor visibility. ...
