The invention discloses a pneumatic lifting upender
system for dismounting and mounting a high-pressure
oil pump. The pneumatic lifting upender
system comprises a console, a
plunger carrying platform, a mechanical arm
assembly I and a mechanical arm
assembly II, the first mechanical arm
assembly comprises a first mechanical arm and a first assembly used for driving the first mechanical arm to move front, back, left and right. The second mechanical arm assembly comprises a second mechanical arm and a second assembly used for driving the second mechanical arm to move front, back, left and right. The
plunger carrying platform is used for placing a high-pressure
oil pump plunger; the console is used for controlling the first mechanical arm to grab, rotate and lift the high-pressure
oil pump and controlling the second mechanical arm to disassemble and extract the plunger. The high-pressure oil pump can be lifted and rotated accurately and efficiently, the plunger of the high-pressure oil pump can be disassembled accurately and efficiently,
mechanization is improved, and meanwhile the hidden danger that potential threats are caused to the life of workers is reduced.
