Abstract

This invention relates to the field of hydraulic cylinder disassembly technology, and discloses a hydraulically assisted precision disassembly device and method for hydraulic cylinders of emergency doors. The device includes a disassembly frame, on which a clamping assembly, a winding assembly, a fixing assembly, and a moving assembly are mounted. The clamping assembly includes a fixed first clamping plate and a movable second clamping plate. The clamping distance between the clamping plate and the first clamping plate is adjusted by a drive mechanism to accommodate hydraulic cylinders of different specifications. The fixing assembly is suspended below the disassembly frame by the winding assembly and is used to support and fix the bottom of the hydraulic cylinder. The moving assembly is located at the bottom of the disassembly frame and is used to move the device. This invention, by integrating adjustable clamping, bottom fixing, lifting adjustment, and moving functions, achieves precise and stable disassembly of hydraulic cylinders of different specifications, improving the efficiency and safety of maintenance operations.
