An underwater structure maintenance robot for offshore engineering drilling platform

Abstract

The invention discloses a robot for overhauling an underwater structure of an ocean engineering drilling platform. A supporting plate is horizontally arranged at the top of the walking ship body. Sliding rails are arranged on the two sides of the plate face of the supporting plate in the horizontal direction. A base is connected to the sliding rail in a sliding manner; a manipulator fixing base isfixedly arranged on the surface of the base; the propeller is driven by the four blade vertical driving devices to realize the adjustment of the underwater height of the walking ship body; the propellers are driven by the blade transverse driving devices on the two sides of the bow of the walking ship body to drive the walking ship body; the walking ship body can advance in water; through the synergistic effect of the blade vertical driving device and the blade transverse driving device; the robot body can be prevented from shaking and deviating due to the fact that the walking ship body is disturbed by water flow in water, the mechanical arm is arranged at the top of the walking ship body, the inspection robot can complete grabbing and taking actions, and welding operation on a drillingplatform is achieved through the welding gun at the bottom of the walking ship body.

Description

technical field [0001] The invention belongs to the technical field of ocean engineering applications, and in particular relates to an underwater structure maintenance robot of an ocean engineering drilling platform. Background technique [0002] Marine engineering refers to new construction, reconstruction and expansion projects aimed at the development, utilization, protection and restoration of marine resources, and the main body of the project is located on the seaward side of the coastline. It is generally believed that the main content of marine engineering can be divided into two parts: resource development technology and equipment and facility technology, specifically including: sea reclamation, offshore dam engineering, artificial islands, offshore and submarine material storage facilities, cross-sea bridges, and submarine tunnel projects. Submarine pipelines, submarine electric (optical) cable projects, exploration and development of marine mineral resources and it...

AI Technical Summary

Problems solved by technology

[0004] 1. Existing underwater maintenance robots are easily disturbed by water flow during operation, prone to body shaking and offset, and cannot navigate normally in narrow spaces, and a single underwater robot has limited payload and layout space, and cannot carry multiple operating tools , can not complete grasping, fetching, welding and other operations at the same time;

[0005] 2. Existing underwater maintenance robots usually do not have a platform to build a multi-axis manipulator, so that the manipulator cannot be adjusted in multiple dimensions when operating underwater, so that the manipulator has certain limitations during maintenance, and it is not easy to overhaul the robot Maintenance of drilling platform equipment
