Robot for installing groove-type large-caliber pipeline connector in deepwater complex environment

Abstract

The invention discloses a robot for installing a groove-type large-caliber pipeline connector in a deepwater complex environment. The robot is integrally shaped similarly as a portal crane; fixing side wings of the robot adopt openable and closable structures, open and close through clamping parts and clamp two pipelines to be connected around a connection point; mechanical arms of the robot form reciprocable movable connection with a screw sliding table. Due to adoption of a series of technical measures, the robot can connect horizontal pipelines and inclined or even vertical pipelines; the mechanical arms and the fixing devices of the robot can be flexibly adjusted according to pipe diameters of the specific connected pipelines, so that needs of connection construction of different models of connectors can be met; through coordination of an airbag and a driving propeller, adjustment on an underwater posture of the robot is achieved, so that the robot has relatively high mobility and flexibility; a main control device of the robot is arranged on a mother ship, so that the structure of an underwater working part is simplified.

Description

technical field [0001] The invention relates to an installation operation robot in a deep water complex environment, in particular to an installation operation robot for a large-diameter pipeline groove type connector in a deep water complex environment. Background technique [0002] The connection and installation operation of deep-sea oil and gas pipelines has a harsh working environment, which has high technical requirements for pipeline connection construction. In particular, there are strict requirements for the automatic operation and installation quality of pipeline connections. [0003] Groove connector is currently a relatively advanced connector for large-diameter pipelines in deep-water complex environments. It has high reliability and good sealing performance, and is especially suitable for the connection of large-diameter pipelines in deep-water complex environments. [0004] With the vigorous development of my country's offshore oil and gas fields, the number ...

Problems solved by technology

[0007] However, its price is relatively expensive, and it is mainly suitable for pipe connections with small diameters. Currently, the largest specification and model range on the market is 4-168mm, and there is no suitable for large-diameter pipe connections.

[0008] In recent years, grooved connectors for large-diameter pipelines have been successfully developed and have been widely used. Due to the lag in the development of the installation robot for the matching grooved connectors in deep water operations, the degree of automation is low, reliability, and There are many deficiencies in handling performance and operating flexibility, which limit the scope of application of grooved connectors.
