Multifunctional climbing wall painting robot

Abstract

The invention discloses a multifunctional climbing wall painting robot, comprising a paint spraying device and elastic wheels. The paint spraying device comprises a main rotary cylinder, a mechanical arm, an auxiliary rotary cylinder, a main spray nozzle, a telescopic cylinder and an auxiliary spray nozzle. The elastic wheel comprises a wheel body, a connecting plate, a spring connecting rod and a support seat. The climbing wall painting robot is not only able to protect all the driving wheels effectively attached to the irregular work surface, and avoid the driving force and the adhesion from being affected, but also able to finish painting work effectively in a large area of working condition or a complex working environment, and doesn't need artificial paint repair again.

Problems solved by technology

[0004] As known, the wall-climbing robot is also called the wall mobile robot, which is an automated robot that can climb on the vertical wall and complete related operations. Since the vertical wall operation belongs to the category of extreme operations, the wall-climbing robot is also called the extreme Operating robots, which include wall-climbing painting robots for spraying the surfaces of objects such as large storage tanks or ships; At the front end of the mechanical arm of the wall-climbing painting robot, the corresponding painting operation is carried out by controlling the walking of the wall-climbing painting robot; however, in long-term practical applications, it is found that the existing wall-climbing painting robot has the following deficiencies: 1 1. Under the working condition of large-scale painting operation, not only the painting efficiency is relatively low, but also the thickness and uniformity of the painting cannot be effectively guaranteed, and it may be necessary to manually touch up the painting to meet the operation requirements; 2. In complex working conditions When carrying out wall-climbing painting operations in an environment, some unconventional curved surface parts cannot be effectively painted, and these parts have to be manually repainted to fully complete the painting operation;

[0005] In addition, the car body structure adopted by the existing wall-climbing painting robot is a rigid car body structure driven by four wheels, that is, the four driving wheels connected to the car body are rigidly fixedly connected, so the wall-climbing painting robot There is no problem with stable walking operations on the working surface, but once it is spraying on the surface of oil storage tanks and large ships, it will be affected by the irregular outer surface of the storage tanks, ships and the rigid body of the wall-climbing painting robot. The four driving wheels of the wall-climbing painting robot will have different adhesion forces, so it is very easy for a certain driving wheel of the wall-climbing painting robot to be unable to attach to the working surface stably, which will not only affect the driving of the wall-climbing painting robot Force, as well as its overall adhesion on the work surface, and in severe cases, it will also cause deviations between the route of the wall-climbing painting robot during the operation and the planned route, and ultimately cause the application party to suffer corresponding economic losses; in summary As mentioned above, due to the fact that the existing wall-climbing painting robots not only have a single function in the application, but also need manual repainting relief, and they are also prone to deviations, resulting in labor and material costs and high costs, so it is very unfavorable for promotion. and application
