Abstract: In view of problem that drill pipe transportation depends on manual operation in vane welding process of spiral drill pipe, travelling bogie was applied to vane welding station of spiral drill pipe, which realized transportation of drill pipes between loading and unloading stations and two welding stations. Control program of the travelling bogie was programmed by PLC-FX3U to achieve joint coordination between the travelling bogie and welding station. Application results show that transport time of the entire drill pipe transport process was shortened by nearly half and the efficiency was increased by about 43% after use of the travelling bogie.
