The specific embodiment
A kind of method of rotating the thick steel pipe of walking rails assembly unit welding manufacturing large diameter and extra comprises the steps:
(1) carries out site clearing, smooth at the construction field (site), lay track in smooth solid place.Assembling place in scene is carried out cure process, guaranteed that flatness, foundation capability satisfy the enabling capabilities of the thick steel pipe assembling of large diameter and extra, welding, avoid differential settlement in the welding procedure to influence spelling, the welding quality of steel pipe.
Track is measured setting-out to the place before installing, the superelevation part is measured, cut to elevation to the track installation site, low-lying location is mended and is filled out levelling, smooth-going degree and rail top face elevation that the control track is installed, take a mode of pad to be adjusted in case of necessity, to guarantee the installation flatness of track.The smooth-going degree of described track be the track upper surface at grade.
Described track length equals the length summation of the thick steel pipe of large diameter and extra that need weld in orbit at least, can carry the thick steel pipe total length of large diameter and extra that need weld to guarantee track.
(2) track of laying is carried out smooth-going degree, elevation detection, adjusts.On smooth solid ground parallel orbit 6 is installed, is guaranteed the top absolute altitude unanimity of parallel orbit.
(3) walking flatcar by computer-controlled carrying, operation, rotation steel pipe to be welded is set in orbit, on the track limit operating platform that can extend to steel pipe outer upper ends to be welded is set, establish on the operating platform by computer-controlled automatic welder(welding machine).At least establish four walking flatcars on the described track, carry with two walking flatcars that are distributed in interval distance the bottom of each steel pipe to be welded.For guaranteeing that the walking flatcar can adapt to the different diameter steel pipe of carrying, two supporting frame group that support rotation driving wheel and rotation driven pulley adopt the adjustable distance design, and the maximum spacing 130cm~200cm that adjusts can adapt to different-diameter steel pipe assembling construction.The supporting frame group spacing determines that the back adopts bolt to connect mode and vehicle frame is fixed.
(4) two steel pipes to be welded are carried with two walking flatcars respectively, on every section lifting steel pipes to two to be welded walking flatcar, open the pipe end butt joint that the walking flatcar makes steel pipe to be welded.Finish adjustment, and the fixing walking flatcar of the butt joint of these two steel pipes and docking site weld spacing by computer-controlled walking flatcar, will be put in the butt weld of these two steel duct to be welded by computer-controlled automatic welding tractor.
Automatic welder(welding machine) is installed in operating platform, is debugged automatic installation for welding, set automatic welder(welding machine) 2,23 arc welding gun head 1,10 welding wire feeding speed, be symmetrically welded the ectonexine weld seam with the welding procedure of approval.
(5) finish the rotation of steel pipe to be welded on the walking flatcar by computer control, simultaneously adjusting speed that electric rotating machine drives the rotation driving wheel by computer control reaches with speed of welding and is complementary, also should be reached by the speed of the motor-driven trailing wheel of tending to act of the automatic welding tractor of computer control adjustment and being complementary of speed of welding and rotation driving wheel speed, realize the inside and outside position of this butt weld is welded with automatic welder(welding machine) and automatic welding tractor simultaneously, finish the welding of two steel pipes to be welded.
(6) repeating step (4) to (5) to the welding procedure of whole steel pipes to be welded is finished.
(7) to the welded still pipe of finishing detect, evaluation quality.Comprise detection and the evaluation of butt welded seam.
