Description

Technical Field

[0001] The utility model relates to the technical field of pressure storage cylinder manufacturing, in particular to a pressure storage cylinder outer surface processing device. Background Art

[0002] The pressure storage cylinder of the hydraulic operating mechanism of the high-voltage circuit breaker in the power system belongs to the energy storage component of the operating mechanism. It is equipped with a piston inside, which divides the inner cavity of the pressure storage cylinder into two parts, one part is filled with hydraulic oil, and the other part is filled with high-pressure inert gas. When the mechanism is working, it is first pressurized to make the hydraulic oil in the oil tank fill into the pressure storage cylinder. The piston moves to the gas side under the push of the hydraulic oil to realize energy storage.

[0003] The pressure storage cylinder is usually made of seamless steel pipe, which is inconvenient to rotate during surface processing. For example, the process steps for spraying paint for anti-corrosion treatment on its surface are usually to place the pressure storage cylinder statically on a work platform and perform manual cleaning or painting operations. During the operation, the pressure storage cylinder is static and needs to be flipped over an angle after completing the surface treatment work on the upper part of the platform, and then the untreated surface of the bottom is treated. Due to the large weight and volume of the pressure storage cylinder, it usually takes several people to flip it over, resulting in low efficiency of the surface anti-corrosion treatment of the pressure storage cylinder and high labor consumption, resulting in high production costs. In addition, the flipping method in the existing surface anti-corrosion treatment process causes the pressure storage cylinder to be unable to flip continuously, which easily leads to the problem of uneven spraying on the surface of the pressure storage cylinder.

[0004] Therefore, it is necessary to design an anti-corrosion treatment system that can be rotated during the cleaning and painting process of the pressure storage cylinder to improve work efficiency, save labor costs, optimize the uniformity of surface spraying, and improve the quality of surface anti-corrosion treatment.
