A waterproof and dustproof ice-scraping cylinder for sanitation vehicles

Abstract

The invention discloses a special waterproof and dustproof ice scraping air cylinder for an environmental sanitation vehicle. The special waterproof and dustproof ice scraping air cylinder comprises a stainless steel cylinder body, a piston rod, a positioning body and a protection cover. The stainless steel cylinder body is of a cylindrical structure with openings in the front portion and the rear portion. A front end cover and a rear end cover are arranged in the front opening and the rear opening of the stainless steel cylinder body in a sealing manner correspondingly. The piston rod penetrates the opening of the front end cover and is arranged in the stainless steel cylinder body. A piston rod sealing ring and an oil bearing are arranged between the interior of the opening of the front end cover and the piston rod. The end, located in the stainless steel cylinder body, of the piston rod is further provided with a piston. The positioning body is arranged on the outer surface of a cover opening of the front cover. The protection cover is fixedly matched with the positioning body and meanwhile penetrates the piston rod to be connected to the front end cover in a sleeving manner. The problem that an existing environmental sanitation vehicle air cylinder is prone to being affected by the outside environment is solved, the structure is simple, and water and dust can be efficiently prevented. Meanwhile, an ice layer formed on the piston rod of the air cylinder through temperature difference changes can be effectively scrapped away, and the service life of the environmental sanitation vehicle air cylinder is prolonged.

Description

technical field [0001] The invention relates to the technical field of cylinder protection, in particular to a special waterproof, dustproof and ice-scraping cylinder for sanitation vehicles. Background technique [0002] At present, urban environmental governance can effectively beautify the city and reduce pollution. Sanitation vehicles play an important role in the process of environmental governance, which greatly reduces manpower and material resources. In the prior art, since sanitation vehicles are mostly used in workplaces with large dust, large temperature differences, and harsh environments, the cylinder of the vehicle is used as the core component. It is easily affected by the external environment, the service life is reduced, and it is not easy to replace the cylinder when it fails, which is very inconvenient for environmental management personnel. Therefore, we are in urgent need of a special cylinder for sanitation vehicles with simple structure, low cost, eff...
