The invention relates to a steel
pipe automatic rotating and spraying
system and a steel
pipe rotating and spraying process. The steel
pipe automatic rotating and spraying
system comprises a supporting plate and a spraying device; mounting holes are uniformly formed in the supporting plate; through the mounting holes of the supporting plates, the steel pipe automatic rotating and spraying
system is mounted on external mobile equipment; the spraying device is mounted at the top of the left end of the supporting plate; and the spraying device comprises an
electric arc spraying
machine, a fixingframe, a rotating frame, a rotating motor, a rotating connecting plate, a rotating mechanism, a rotating shaft, a clamping mechanism, a guiding mechanism, a rotating telescopic column, a follow-up connecting plate, an angle adjusting rod and a buffering spring. According to the steel pipe automatic rotating and spraying system, difficult problems that a
user needs to hold spraying gun to perform spraying operation on an existing blow-off pipe during performing
electric arc spraying on the existing blow-off pipe, potential safety hazards are available in manual operation, a spraying gun power supply wire is easy to wind during
electric arc spraying, breakage can be caused during spraying a
welding wire and so on can be solved.
