Abstract: The present disclosure relates to a rope traction type grinding, cleaning, and coating integrated operation robot. The operation robot includes a hanging basket, a first traction mechanism connected to the hanging basket, a grinding mechanism arranged in front of the hanging basket, and a cleaning and spraying mechanism and a spring reaction force regulation mechanism arranged in the hanging basket. The first traction mechanism includes first ropes for connecting the hanging basket and first rope winding mechanisms. The cleaning and spraying mechanism includes a first vertical plate and a second vertical plate that are arranged in parallel in a vertical direction. A cleaning nozzle and a spraying nozzle are mounted on the first vertical plate. From the above technical solution, it can be seen that the operation robot adopts a rope traction manner, and has the advantages of large work space, low mechanism inertia, and accurate and reliable location.

Abstract: A flexible-rope-driven hybrid spray painting robot mechanism includes a static platform framework, a flexible-rope-guided pulley train, flexible transmission ropes, a moving platform, and drive mechanisms. A moving platform casing is driven by eight flexible ropes in parallel, to realize three degrees of freedom of translation thereof. A spray gun is connected in series to the moving platform casing via a universal joint cross, and is driven by four flexible ropes in parallel, to realize two degrees of freedom of rotation thereof. Beneficial technical effect of the present invention: The flexible ropes are used in parallel to control three degrees of freedom of translation and two degrees of freedom of rotation of the end spray gun, achieving advantages of a small movement inertia and flexible movement. Electric drive devices are placed together in a bottom layer of the static platform framework and are isolated from a spraying space.
