Automatic two-component coating spraying robot for steel bridge deck and spraying method

Abstract

The automatic spraying robot comprises a movable base, Mecanum wheels are installed at the bottom of the movable base, and the Mecanum wheels are in transmission connection with a power system of the movable base; a translation track is arranged on the movable base, a translation platform is arranged on the translation track, a lifting device is installed on the translation platform, a horizontally-arranged telescopic rod is installed at the lifting end of the lifting device, a first spray head and a second spray head are installed on the telescopic rod, and the first spray head communicates with a first paint spraying box through a pump body; the second spray head communicates with the second paint spraying box through the pump body. The omni-directional moving wheel platform is adopted to drive the spraying arm to automatically walk in the direction perpendicular to the moving direction of the bridge floor, and the spraying efficiency and uniformity can be greatly improved. When the movable platform moves, the spraying arm automatically moves along the track on the platform at the same time, and efficient walking of the spraying arm is achieved.

Description

technical field [0001] The invention relates to spraying equipment, in particular to an automatic spraying robot and a spraying method for two-component paints for steel bridge decks. Background technique [0002] At present, the two-component spraying operation of steel bridge deck mostly adopts manual construction, and there are also semi-automatic equipment that uses truss manipulator spraying and manual dragging construction. Due to the high quality requirements of spraying, the efficiency of manual operation is low, and protective masks are required, which is labor-intensive; and during the construction of semi-mechanized equipment, there is also uneven manual dragging, and the equipment as a whole is large, and the construction operation is affected by the site. The limitations are very large and the application area is narrow. At the same time, due to the two-component construction, due to the reaction between the components, the solidification is fast, and clogging ...

AI Technical Summary

Problems solved by technology

Due to the high quality requirements of spraying, the efficiency of manual work is low, and protective masks need to be worn, and the labor intensity is high; while semi-mechanized equipment construction, there is also the phenomenon of manual dragging unevenness, and the overall size of the equipment is large, and the construction work is limited by the site. Very limited, narrow application

At the same time, due to the two-component construction, due to the reaction between the components, the solidification is faster and the clogging phenomenon is prone to occur.
