Furthermore, the device features a rotation function. A pair of rotary drive motors on the U-shaped support drive a rotating gearbox, which in turn drives the rotating shaft tube and U-shaped set block to rotate, easily rotating the vertical drill pipe to a horizontal position, meeting the requirements of various operating angles. It is worth mentioning that the disassembly process is also efficient and convenient. The disassembly screw module drives the disassembly robot arm to stably extend and retract horizontally.
