Description

Technical Field

[0001] The utility model relates to the technical field of cold oil pump auxiliary tools, and particularly relates to a replacement tool dedicated to an oil-cooled oil pump of a high-voltage rectifier transformer. Background Art

[0002] The oil pump bearing of the oil-cooling device of the rectifier transformer is a vulnerable part with a certain service life, and it needs to be disassembled and repaired after being used for a certain period of time. Since the oil pump is installed in a hanging manner, during the disassembly and assembly process, there are many handling problems such as moving the position of the oil pump and raising it into place. Especially when the site is paved with cobblestones and the installation position is narrow and not easy to exert force, there are many potential safety hazards in the replacement and repair work. For example, in Chinese patent, the authorized announcement number is CN208235919U, which discloses a lifting platform with good stability and easy to move for indoor decoration. By unfolding the fixed rod and lowering the universal wheels by using the foot-operated hydraulic cylinder, the lifting platform is more stable during use, and the phenomenon of the lifting platform tipping can be effectively avoided. However, this solution does not have a special tilting and lifting mechanism for the needs of oil pump replacement, resulting in inconvenient operation and possible impact on safety when replacing the oil pump; for the replacement operation of this specific equipment of the oil-cooled oil pump of the high-voltage rectifier transformer, it cannot provide sufficient support and guarantee.
