An underwater foundation pile obstacle avoidance maintenance robot

Abstract

The invention discloses an obstacle avoiding maintenance robot for underwater foundation piles, and applied to maintenance of underwater column-shaped foundation piles. The robot comprises a rotating platform used for being fixed on the foundation piles and a working platform connected with the rotating platform, wherein the working platform comprises an upper mounting part and a lower mounting part in rotating connection with the upper mounting part; an avoiding hole is formed in each of the upper mounting part and the lower mounting part; an upper locking mechanism is arranged on the upper mounting part; a lower locking mechanism is arranged on the lower mounting part; the upper locking mechanism or the lower locking mechanism is used for locking the working platform on the foundation piles; at least one lifting device is mounted on the rotating platform; the lifting device is connected with the working platform and drives the working platform to move along the foundation piles; the lifting device further enables the rotating platform to rotate along with the rotation of the working platform. The obstacle avoiding maintenance robot for underwater foundation piles has the characteristics of automatic obstacle avoidance and high cleaning efficiency.

Description

technical field [0001] The invention relates to the technical field of cleaning and detection, in particular to an underwater foundation pile obstacle avoidance maintenance robot. Background technique [0002] With the development of road traffic and bridge technology, more and more bridges are used on oceans and rivers, such as sea-crossing bridges and viaducts. Bridge foundation piles are the key supports that affect the safety of bridges. Since some bridge foundation piles need to be below the water surface for a long time, such as the foundation piles of cross-sea bridges, they are affected by harsh marine meteorological conditions and complex beach geological environments, resulting in foundation piles. Factors such as material variation and tidal construction difficulties cause corrosion and damage to foundation piles. In addition, the biochemical process caused by marine microorganisms attached to marine foundation piles also accelerates the corrosion of foundation pi...

AI Technical Summary

Problems solved by technology

Due to the existence of the cathodic protection block, the conventional method of maintenance along the foundation pile will hit the cathodic protection fast, which will hinder the movement of the foundation pile maintenance robot and cannot work effectively

However, the use of large-scale foundation pile maintenance equipment is costly and difficult to maintain. Therefore, it is necessary to improve the obstacle avoidance ability of existing underwater foundation pile maintenance robots.
