Description

Swing arm type rust removal polishing robot adaptive to surface of ship rib Technical Field The invention relates to the technical field of swing arm type rust removal polishing robots, in particular to a self-adaptive swing arm type rust removal polishing robot for ship rib surfaces. Background The ship rib is used as a core bearing part of a ship body structure, is used in a marine environment for a long time, and the surface of the ship rib is easy to be corroded by seawater, attached by marine organisms and oxidized by the atmosphere, so that a thick corrosion layer and an old coating are formed, if rust removal polishing treatment is not performed in time, the structural strength and corrosion resistance of the rib can be obviously reduced, the service life of the ship is shortened, and even potential safety hazards of sailing are caused. Therefore, the regular rust removal and polishing of the ship ribs is a key process in the maintenance of the ship, and is directly related to the navigation safety and the operation benefit of the ship. At present, the ship rib derusting and polishing operation is mainly divided into three modes of manual polishing, traditional mechanical polishing and preliminary automatic polishing, but the three modes all have the problem of more outstanding dust pollution, and the efficient, environment-friendly and accurate polishing operation is difficult to realize, and the specific defects are as follows: The traditional manual polishing mode relies on tools such as an angle grinder, a grinder and the like to operate, a large amount of metal dust is generated in the operation process, the dust is mainly metal oxides such as iron, manganese, nickel and the like, inhalable particles with the particle size smaller than 10 mu m occupy higher proportion, are easily inhaled by operators, cause serious occupational diseases such as pneumoconiosis and the like after long-term exposure, and seriously threaten the body health of the operators. Meanwhile, dust generated by manual polishing does not float in an organization manner, the dust can be attached to the surface of a ship body and operation equipment, abrasion of the equipment is accelerated, the subsequent coating quality is influenced, the dust can be diffused into the surrounding atmosphere environment, air pollution is caused, the development requirements of the modern ship industry on environmental protection are not met, the manual polishing efficiency is low, the polishing quality is uneven, the complex curved surface structure of the ship ribs is difficult to adapt, and the large-scale and standardized maintenance requirements cannot be met. In order to improve the operation efficiency, some enterprises adopt traditional mechanical polishing equipment to carry out rib derusting and polishing, and although the manual investment is reduced to a certain extent, the problem of dust pollution is not effectively solved. The traditional mechanical polishing equipment lacks a targeted dust collection structure, dust generated by polishing is directly diffused into an operation environment, and especially when the ship cabin and other closed spaces are operated, the dust concentration can be rapidly increased, so that the health hazard to operators is aggravated, and potential safety hazards such as explosion and the like can be caused by dust accumulation. In addition, the rigid structure of traditional mechanical polishing equipment can not adapt to the curved surface radian and size difference of ship ribs, the problems of incomplete polishing, surface scratch and the like easily occur in the polishing process, meanwhile, dust is attached to the surface of a polishing head, the polishing efficiency and the polishing precision can be reduced, and the operation quality is further influenced. Therefore, the application provides the swing arm type rust removal polishing robot adaptive to the surface of the ship rib.
