Abstract

The invention relates to a six-degree-of-freedom underwater moving platform. An open frame type structure is employed, so that the weight and the size of the platform are reduced and the platform is suitable for more kinds of working areas; various structure of the platform are controlled via cables and the bottom of the platform is provided with a welding control box, so that the function of real-time welding tracking of the platform is guaranteed and the welding quality is improved; the platform can be turned simply via air bags, so that the cost is reduced and the posture control of the platform is simplified; via two vertical propelling devices and four horizontal propelling devices, six-degree-of-freedom movement can be realized; by combining the platform movement posture control mode and universal wheels, a wall climbing function is fulfilled, and the platform can move freely on any working planes. With the platform structure and with the functions of wall climbing and real-time welding tracking, an open frame type underwater working robot which is novel and stable and is low in cost is realized.

Description

Technical field [0001] The invention relates to the technical field of underwater robots, in particular to a six-degree-of-freedom underwater mobile platform with six degrees of freedom and a stable welding function. Background technique [0002] Underwater welding robots can be widely used in underwater maintenance of large ships, marine exploration platforms, marine drilling platforms, etc., maintenance of nuclear power facilities, underwater welding operations in harsh environments and other fields, and have broad application prospects. The underwater welding robot should meet the requirements of adapting to multiple environments, long-term stable operation, sufficient structural strength, and easy maintenance. The current underwater welding robots are mostly large-sized underwater crawlers that lack flexibility, and the multi-degree-of-freedom underwater mobile platform with welding function needs to be further developed. An existing underwater welding experiment platform ca...
