Problems solved by technology

[0012] Furthermore, if only two anchor points are used, such as in existing systems, there is a substantial risk of the device swinging and causing one of the cables to break, and one of the consequences of such a break is to overload the remaining anchor points, causing the device to drop

Embodiment Construction

[0034] The purpose of the present invention is to use a cable construction to suspend a mobile platform developed to couple the oscillating mechanism that performs the painting process and also move quickly and precisely to ensure the quality of the painting on the hull of the ship, but Not limited to this application.

[0035] For a better understanding of the invention, we shall illustrate it by means of the following description, which is a preferred embodiment of the invention. However, it will be apparent to those skilled in the art that the present invention is not limited to this particular embodiment.

[0036] The present invention relates to the arrangement of cables for suspending a mobile platform (3), novel because the platform is positioned by four cables, where its suspension system is placed on a free "Mecanum" wheel that behaves like a sphere (21) on. In this case it has two fixed pivots at deck level and four moving pivots at the ends of the mobile platform ...

Abstract

The present invention relates to an automated painting system for oil tankers, which includes a mobile platform and an oscillating arm. The assembly only works by controlling cables, reels and wheels. This approach is aimed at painting large vertical walls. The painting platform is suspended by four cables, each cable being attached to a pivot on the mobile platform and two fixed pivots in addition to four winders. The winders contain a servomotor in a synchronous serial system. The cables are made of low-weight polyethylene. Each cable is attached to its own winder. Suspension is carried out with the aid of two tailored cranes and initiated by a further giraffe crane.

Description

technical field [0001] The present invention relates to techniques for ship and oil platform equipment and building maintenance. More specifically, the present invention relates to robotic automated painting techniques. Background technique [0002] Regardless of the manner in which the painting is done, the state-of-the-art techniques for painting vertical surfaces use devices that generally follow the same principles of traction and suspension using cables. [0003] Typically, two motorized cable pullers, using counterweights to balance the weight of the suspended system; there are many publications in this field. Author and inventor Patricio Gonzalez Vivo developed a painting device suspended by two cables, each pulled by a motor located on the side of the upper part of the system. The cable uses a counterweight as it passes through the motor. The disclosed device is controlled via software by scripting and allows images to be drawn onto the vertical wall on which the ...
