Conduit support T-shaped connector automatic welding running device

The utility model relates to a conduit support T-shaped connector automatic welding running device, which is applicable to the field of automatic welding equipment technology. Two semicircular metal rings form an annular track; hinges are fixed to an outer surface of one joint end of the two semicircular metal rings and eccentric wheel lock catches are fixed to an inner surface of the other joint end of the two semicircular metal rings; three to six track supporting brackets are fixed to the inner wall of the track uniformly; two ends of the inner wall of the track are provided with circular conical surfaces; a gear ring is disposed in the middle of the outer wall of the track; and a running gear of an automatic welding running trolley is meshed with the gear ring on the outer wall of the track. The automatic welding running trolley is clamped to the track; the eccentric wheel lock catches realize locating and locking of the track; with a two-section structure, the track can be installed to a T-shaped conduit support easily during welding; with inner sides of cylindrical surfaces on two ends being the conical surfaces, the track enables the locating of the automatic welding running trolley; and a running motor can drive the automatic welding running trolley to run along the track.
