Steel pipe mounting device

The utility model relates to a steel pipe installation device capable of avoiding steel pipe butt joint deflection, in particular to a steel pipe installation device which comprises a containing plate, the front side and the rear side of the upper surface of the containing plate are connected with the lower surfaces of two fixing frames in a sliding mode respectively, conveying assemblies are arranged in the fixing frames, and a worm is driven by a stepping motor c to rotate. The worm rotates to drive the worm wheel to rotate, the worm wheel rotates to drive the placing plate to rotate, the placing plate rotates to drive the steel pipe to conduct angle adjustment, the stepping motor d drives the screw rod d to rotate, the screw rod d rotates to enable the screw rod d to move upwards from the interior of the threaded barrel, then the height of the lifting plate and the steel pipe is increased, and deflection during butt welding of the steel pipes is avoided. The problems that an existing device cannot adjust t
